The war drums were like thunder and the flags were like the sea. The attacking team of Xuzhou Army resisted countless simple flight ladders, pushed three large ladder trucks with key protection, shouting and moving forward quickly, like waves, surging towards the towering walls of Hangu Pass...

Under Hangu Pass, a large number of Xuzhou military commanders built dozens of simple fortifications with shields, covering their archers to shoot feather arrows on the wall, suppressing the Cao army guards on the wall, and covering the infantry team to charge and attack.

With the rain of arrows shot by Cao's army, they rushed to Hangu Pass for a lot of price. The most cruel battle of Ant-Environment in the era of cold weapons began. The Xuzhou army put hundreds of light flying ladders on the wall. The three-meter-long flight was magnificent and stomped upwards. The Cao army guards threw down countless gray bottles of wooden sheep-head stones, poured boiling gold juice, and carried a big wood to hit Xuzhou soldiers. The fierce shouts echoed in the Hanguan Valley Road, shocking the earth. From time to time, soldiers fell from the top of the towering wall. The shrill screams echoed on the battlefield of Ant-Environment, which was touching.

As I said, Hangu Pass, which has never been attacked by the enemy from the front since the construction of the pass, is too solid and the terrain is too favorable. The ten-mile valley road is narrow and difficult to move. The only open area under the pass is also rugged with rugged rocks and ravines, and large siege weapons are difficult to move. Even if the large siege weapon with the best attack effect is forced to be the most tightly defended by the offensive and defensive party, it cannot threaten the relatively weak siege wall built on the hillside. In the face of such unfavorable terrain, the most effective siege weapon of the attacker is left with a light staircase without any protection. It is impossible to effectively and quickly climb the city, and must pay a heavy price in the ants siege.

Even the Xuzhou Army, which is already the strongest in the world, is no exception. Although the soldiers of the Xuzhou Army have already taken out the courage of Superman to fight and still charge without hesitation with the single weapon of siege, the result of this is still meaningless. It can even be said that moths to the fire, and the Hangu Pass defenders, who are also in sufficient force and materials, fired thousands of arrows at one go, and the arrows are like rain. The Xuzhou Army has to pay a heavy price for every step forward. With courage and experience, it finally rushed to the wall, and then climbed up and charged on the ladder, and then rushed upwards.

By the head-on attack of stone wood and gold juice, countless soldiers in Xuzhou were seriously injured, and countless people were buried under the pass. Even if they tried hard to rush up the pass, they would be besieged and killed by enemies ten times more than their own, and they died even more tragic. The battle of Ant Attachment lasted for more than half an hour. There were less than twenty soldiers in Xuzhou who could rush up the pass, and no soldier could hold on until the follow-up companions rushed up the pass, and rescued him. The biggest attack was three ladder vehicles, and they were also burned by the rockets and swallowtail torches of Cao's army during the journey, and they failed to get on the pass, providing help to the Xuzhou soldiers.

The Xuzhou army was difficult to attack, and the Cao army was not easy to defend. Although the Cao army was in Guanzhong area before, in order to resist the harassment and invasion of Ma Teng, Han Sui rebels and Qiang tribes, they fought hard to defend the city and had rich experience. However, this was the first time that Cao army encountered such a fierce attack team against Xuzhou army. When there was almost no hope of breaking the pass, the enemy would charge without hesitation. When the ladder truck had already ignited a sky-high fire, the enemy was still pushing the ladder truck forward desperately, even if it was

The clothes and hair were already on fire and continued to move forward. The Xuzhou soldiers, who were covered with arrows and covered with blood, rushed to the wall. After being besieged by enemies ten times more than themselves, they still fought hard and swung their swords. They had to cut at least two or three Cao soldiers before being cut into pieces. One Xuzhou soldier still hugged a Cao army soldier and rolled down the wall and died together. Seeing such a brave and tenacious enemy, the Cao army was still frightened and his legs trembled when they had the advantage of the territory.

The three ladder trucks dispatched by the Xuzhou army for the second time were finally burned by the swift tail torch of Cao's army. In the end, the swift tail torch was completely burned by the swift tail torch thrown by Cao's army less than twenty steps away from the wall, making the Cao army's army escape a catastrophe by chance. Seeing that there was no hope of breaking the pass, Deputy Director Tao finally issued the order to withdraw the injured and injured Ant Attachment team, and the heavy casualties retreated to the rear to rest. After seeing the Xuzhou army retreat like a tide, a huge cheer sounded at Hangu Pass. Countless Cao's soldiers breathed a sigh of relief, glad that his army finally withstood the attack of the Xuzhou army and caused considerable losses to the Xuzhou army.

Cao, who came to the Guanlou to command the battle despite his serious illness, was relieved and quickly arranged to rescue the wounded soldiers, counted the casualties and replenished the guards of the walls. After all, Cao Cao's haggard face also rarely showed some smile on his haggard face and said to the civil and military officials on both sides: "Very good. The facts have proved that as long as we keep the pass tightly and do not come out, we can cause huge casualties to the team of Tao Ying annihilated thieves, and we have hope to persevere until the Tao thieves are forced to withdraw."

"What the lord said is that Hangu Pass has never been attacked head-on since ancient times. As long as our army does not reveal flaws elsewhere and does not give the Tao thieves the opportunity to break through the gate, we will definitely be able to defend Hangu Pass." Cheng Yu nodded and agreed, and then said carefully: "But lord, this attack of the Tao thieves is obviously just a test. They want to find our defense weaknesses in the wall of the gate, and the other is to test the strength of our army's defense. The real battle to attack the key points is still behind."

"It's okay, this is long before I expected." Boss Cao smiled happily: "So I didn't use too many main combat soldiers this time, and only let 30% of the main force and 70% of the auxiliary soldiers guard the pass. This gave the pottery thieves the first wave of siege to the city and the opportunity to rush up the pass wall. It was to let him betray our army's defense efforts, and hope to break the pass head-on and continue to attack the pass wall in the future."

Cheng Yu nodded and smiled, still admiring Boss Cao's courage, courage and scheming, and dared not to deliberately not mobilize too many main elites during the battle to defend the gate. At this time, Guo Jia, who had been observing the movements of the enemy, suddenly coughed and said, "Lord, please see, there are new moves on the pottery thief. It seems that many small cars are coming in the valley."

Boss Cao quickly looked up and looked at the valley road with the original telescope seized on the battlefield. When he saw the Xuzhou army pushing many unicycles from the valley road, he unloaded the cargo in front of the Xuzhou army. The truck was full of firewood and grass, and there was nothing else. Boss Cao couldn't help but wonder, "Why are the pottery thieves transporting so much firewood and grass? Do you want to set fire to the gate? Are the pottery thieves so stupid?"

Cheng Yu, Guo Jia and others also looked at each other, not understanding what Deputy Director Tao was going to do, so they had to continue to observe the enemy situation with Boss Cao to judge the next move of the Xuzhou army. The Xuzhou army had no other moves except using wheelbarrows to transport firewood to the front of the pass. Boss Cao and others just saw the firewood of Xuzhou army piled into a small hill outside Hangu Pass. The height of Firewood Mountain quickly exceeded the height of the wall of Hangu Pass. Boss Cao was even more confused and analyzed: "Does the Tao thieves want to accumulate grass into mountains and attack the city with Caoshan? But it is wrong. Caoshan is not only difficult to bear the load, but our army can burn Caoshan into a volcano as long as we pour some turbulent oil and throw some torches down?"

"No!" Guo Jia woke up and exclaimed: "The pottery thief wanted to create a lot of smoke. Hangu Pass is located in the canyon. The thick smoke is difficult to be blown away quickly by the wind. As long as the thick smoke covers the valley, it will be very difficult for us to guard the pass!"

"What?!" Boss Cao was shocked. After a little calculation, he agreed with Guo Jia's analysis and cursed: "Damn the annihilation thief, he is very good at using narrow terrain!"

Sure enough, when the firewood piled up to a certain extent and the wind direction turned to the west, the soldiers of Xuzhou army immediately took action. A large number of infantry carried the firewood to the front of the Guanlou Tower in Hangu Pass, and rushed directly to the next door to the closed door before throwing the firewood grass under the closed door. Although Cao army tried hard to stop it, the Xuzhou army used firewood grass to block the key points and continued to rush forward without hesitation. Soon, the firewood grass was transferred to Hangu Pass. When Caoshan was more than one meter high, the Xuzhou army released rockets and ignited the firewood piles piled up under the closed door. At the same time, they continued to transport firewood and grass to Hangu Pass, desperately increasing the fire. (This tactic is not fictional. During the Tang Dynasty, An Lushan used it to defeat Geshuhan in the Taolinsai Battle.)

The fire quickly ignited, and the fires of several feet high gradually rose several feet high. The flames floated up the walls of Hangu Guanguan, burning the Guankou area to make the Guanlou red. The Cao army soldiers could not stand at all, and forced Cao to leave Guanlou to avoid the fire. At the same time, the army was forced to force the army to strengthen the closing of the door to avoid the fire. However, compared with the fire, the biggest impact on the Cao army was the rolling smoke brought by the firewood pile. The blue-white smoke was blown by the mountain wind, and soon spread the entire east gate of Hangu Guanguan, making it difficult for Cao soldiers to reach out to see their hands, and also made the Cao army soldiers choke and tears flow together, making it difficult to breathe.

With the cover of thick smoke, another round of attack by the Xuzhou infantry began. After wrapping her mouth and nose with a soaked bupa, the Xuzhou infantry carried the ladder and rushed into the thick smoke, putting the ladder on the wall and climbing upwards. The Cao army soldiers lay their bows and crossbows into the thick smoke, wasting countless precious feather arrows in vain and were almost useless. They were also covered by the smoke, and they could not see the enemy clearly. Many Cao army soldiers even did not even notice that Xuzhou soldiers rushed to the wall and swung their swords and guns to fight with the Cao army to fight for the wall and positions.

The most dangerous moment for the Cao army was coming. Forced to helplessly, Boss Cao had to order Zhang He to dispatch an elite reserve team and rush up to the wall to fight fiercely with the Xuzhou army. The wall completely covered by thick smoke was soon shrouded by a sound of fighting. The soldiers on both sides sacrificed their lives to fight in the thick smoke. The swords and swords were red, and the guns were bloody, fighting with their lives, using flesh and blood to charge and defend, and the battle was in a mess. When the troops were absolutely weak, Boss Cao could only send more troops to the wall with tears in his eyes, and launched a military taboo battle with the soldiers who were coming to the gate.

The melee lasted for more than an hour, until the thick smoke slowly dissipated by the mountain wind. Boss Cao was forced to let Dian Wei lead the absolutely elite Hu Ben Camp to fight with injuries, and then he struggled to repel the Xuzhou army's attack. Fortunately, the Xuzhou army obviously did not expect that the heavy smoke in the valley would be so good before this. He did not prepare too much follow-up firewood. In the absence of firewood, he had to give up the third attack operation. Mingjin withdrew from the battlefield of Hangu Pass. However, when he retreated, Deputy Director Tao arranged for the soldiers to shout slogans in unison, "Cao Mengde, next time we will bring ten times the firewood, prepare the coffin!"

The Xuzhou army finally withdrew, and the pile of firewood under the pass was gradually extinguished, but Boss Cao's face was still dark, because Boss Cao was also very clear that the unworthy son-in-law was obviously not prepared this time, and he did not expect that the effect of smoke protection in the valley would be so good, so he did not seize the opportunity to attack Hangu Guanzhong. But next time, the unworthy son-in-law only brought ten times the firewood and grass to attack. The next time, the Xuzhou soldiers who killed the wall on the pass will definitely be the most elite in the Xuzhou army. Whether he can withstand the unworthy son-in-law's next attack will be a matter of two.

Sitting alone on the wall until evening, Cheng Yu, who had smoked marks on his face, returned to the front of Lao Da Cao and said to Lao Da with a hoarse voice: "Lord, the casualties have been counted. In this battle, more than 1,600 soldiers in our army were killed, and 318 people were seriously injured and lost their combat effectiveness, and more than 1,000 were slightly injured."

Boss Cao did not ask about the number of casualties of the Xuzhou army, because Boss Cao knew very well that even if the casualties of the Xuzhou army were more than three times that of the Cao army, Deputy Director Tao could afford to lose. Moreover, after the tactics of making smoke cover proved effective, the proportion of casualties between the Xuzhou army and the self-army would definitely drop significantly again. Therefore, Boss Cao never spoke, but looked at the east side in a depressed mood, staring at the direction where the damn son-in-law was.

Seeing that Mr. Cao was in a bad mood, Cheng Yu had to make excuses to comfort him: "Lord, when our army was cleaning the battlefield, we found that most of the corpses of the corpses were wrapped around their mouths and noses with wet cloth. I think this is a method used by the corpses of the corpses to avoid being choked by smoke. Our soldiers can follow the example next time, and many soldiers will not be choked by thick smoke."

Boss Cao nodded slowly and said weakly after a while: "The Taoist thief will do the same next time, how can our army resist?"

Cheng Yu was speechless, and Guo Jiaze next to him coughed and said, "Lord, Hangu Pass is located in the valley, and our army is passively defending it to the death. After all, it is not a long-term solution. The best way is to divide the troops to set up camp at the Gukou to provide buffer for Hangu Pass."

Cao thought silently that the reason why Cao had refused to leave the gate to set up camp was because Cao knew very well that, given the current situation of the army, camping in Gukou area where there was no barrier protection, would definitely be a severe blow to the Xuzhou army. Therefore, Cao could only hope for the natural danger of Hanguguan that had never been directly attacked by others, and wanted to drag the unfilial son-in-law into the attack and fight hard and then find opportunities to defeat the enemy. However, Cao did not expect that he could use the natural dangerous terrain of Hanguguan, but the unfilial son-in-law could use the canyon terrain and actually invented the tactics of the Long Smoke in the Valley to drag the geographical advantage into balance. If this continues, Hanguguan will sooner or later be defeated by the Xuzhou army. In the unstoppable situation, Cao had to reconsider the establishment of the Gukouguan and fight to the death with the unfilial son-in-law in the wild.

The night wind was getting colder, but Boss Cao's heart was colder than the night wind. He was so weak that he was as old as he was about to go. His expression was both depressed and helpless. However, at this moment, the sound of the routine war drum horns of the Xuzhou army in the valley road in Hangu Pass sounded again. Boss Cao couldn't help but move his lips slightly, revealing a bitter smile, and said to himself: "You are filial to your son-in-law, I really wish I could die early."

"Bitch! Come again!" Dian Wei's curse came from his ears. Then, Dian Wei, who had an injury in the sole of his foot, walked to Lao Da Cao with a lame leg and said, "Lord, our closing of the door is no longer possible. When the pottery thief set fire to the door, we kept splashing the door with water, but the iron sheet outside the door was still burned by fire, and the thick wooden board inside was almost burned, which could not be repaired in a hurry. Finally, I believe that we can only use sacks to block the closing of the door tonight. If more Tiger teams are sent to guard the door, please make an announcement. "

Boss Cao nodded silently, and suddenly asked Dian Wei again: "Junming, do you have the courage to follow me out of seclusion and go to the valley entrance to set up a camp, and fight against Tao Ying to the death?"

"Mo Jiang has long hoped to do this!" Dian Wei agreed happily, and quickly said, "But lord, just let Mo Jiang go. You can stay in Guancheng to rest, your body cannot come out of Guancheng."

"I'm fine, I won't die for a while. Without me, you are not the opponent of the Tao thief." Boss Cao shook his head, and then ordered Dian Wei: "Junming, I don't have the strength to speak loudly. Help me to the wall and summon all the soldiers of the army. I want to give a lecture to all the soldiers of the army. I will say something, you will repeat it for me."

Dian Wei agreed and helped Boss Cao to the wall. Boss Cao ordered the guards to sound the horn of assembly and summoned the soldiers of his own army to gather below the city. After a while, the Cao army soldiers came to the wall and looked at Boss Cao on the wall and waited for the order. Boss Cao didn't wait for the army to gather completely, so he asked Dian Wei to retell his words: "Soldiers, listen!"

"Soldiers, Hangu Pass is in danger. The pottery thieves seized the weakness of Hangu Pass in the valley and used thick smoke to cover his attack. Although we luckily blocked the attack of Tao Yingzhe, the next time, the pottery thieves will definitely do the same thing, bringing more firewood and arson to produce smoke to cover his attack. If this continues, Hangu Pass will sooner or later be attacked by the pottery thieves!"

"Soldiers, we only have one way, that is, go out of the customs, go to the Gukou to set up camp, and go to the Gukou to fight against Tao Ying to the death!"

"The soldiers of the Taoist thieves are more than seven times that of ours. When we go out of the seclusion, we will die for a lifetime! But if we continue to stick to Hangu Pass, we will die for ten deaths! For the last hope of our victory, for our relatives, and our homeland, we can only fight to the death!"

"Soldiers, tell me who was despicable and despicable provocation and provoking the war between us and Yuan Shao's army?"

"Soldiers, tell me who shamelessly preserves his strength, hides outside the battlefield and watches the fire, and wait until our vitality is severely damaged before sending troops to attack us?"

"Soldiers, tell me who brutally took away our Xuchang? Who robbed us of the fertile land of the Central Plains? Who forced us to famine everywhere in Runan, and who drove us to the decaying Guanzhong? He killed countless soldiers of our army who had been through many battles?"

"Tao Ying annihilated the thief! It's Tao Ying annihilated the thief!"

Dian Wei asked for a question for Boss Cao, and the Cao army soldiers under the wall answered neatly. After asking these questions, Boss Cao waved his thin hand and shouted in his greatest voice: "Yes, it's Tao Ying annihilated thieves! I have decided that tomorrow I will bring troops out of the gate, go to the valley entrance to set up camp, and fight to the death with the Tao Ying annihilated thieves! Avenge your revenge for our soldiers, our Xuchang, and all the suffering we suffered! Revenge--!"

"Revenge————!" Dian Wei roared wildly.

"Avenge! Revenge! Revenge!" Tens of thousands of Cao army soldiers roared angrily, roaring in rhythm and neatly. The loud voices were so loud that they also covered up the noise that Xuzhou sling drum team deliberately created.

"Take revenge! Revenge! Revenge--!"

Amid the heartfelt roars of tens of thousands of Cao soldiers, Boss Cao slowly raised his thin face, looked at the bright moon in the night sky, and murmured, "Yu Rang, Miaocai, Yu Jin, Li Dian, Le Jin, Li Tong, Gongda, Zihe, and countless soldiers of our army. Your spirit in the sky, please open your eyes, I will go and avenge you. This time, if I can't send Tao Yingji to vent my anger to you, I will come to you, reunite with you, apologize to you...."
