The rumbling sound was deafening, and a large cloud of smoke gushed out, swallowing Shi Zhuang and You Yong. The two of them were buzzing in their ears, but they could not hear anything for a moment. The two looked at Zhu Yi beside them in horror, but found that the other party had already stuffed two balls of cotton into their ears, and were holding a monocular telescope looking into the distance.

The two looked at each other and both smiled bitterly.

It seems that the conversation between the two just now offended Fatty Zhu, and this guy never thought about reminding them.

"Hehe, let you be proud, now you know it's amazing, right?" The thick smoke in front of Fatty Zhu's eyes was quickly curled by the cold wind, and what appeared in front of him was a terrible scene.

Hearing Zhu Yi's proud voice, Shi Zhuang and You Yong immediately rushed forward and raised the monocular lens in their hands.

Cao Zhen never expected that the Tang army would have weapons to siege the city across such a long distance to Jindou Pass.

Today, the Tang army went out to camp to form an array, but did not see a catapult or a powerful crossbow. Originally, he thought that today was just a threat from the other party. So he placed all the elite support Cao Huan had just brought on the city wall. He wanted to demonstrate. He wanted the other party's Tang army general to see if they could gain advantage on themselves.

But what Tang Jun appeared today was a brand new weapon.

It can easily attack the city walls by crossing several distances.

And it is incredibly powerful.

He lay on the ground, his ears still buzzing, and waves of dizziness kept coming, his face was wet and licking. When he reached out to touch it, his hands were covered with blood.

Only then did he realize that there was still someone pressing on his body, his head hanging softly on his shoulders, and it was Cao Huan standing beside him.

It was not until this time that he realized that just now, there was a loud noise from the opposite side, and bursts of thick smoke gushed out. Ten black things flew out in the air and came towards Jindou Pass. Cao Huan beside him suddenly pressed him to the ground and leaned on him.

"Uncle, uncle!" He suddenly turned over and hugged Cao Huan in his arms.

Cao Huan's armor was inlaid with a good piece of iron sheet, and the best armor was easily torn by these iron sheets. The most fatal one was a big wound on his head, with blood gushing like a spring.

With his hand pressed the wound, Cao Zhen called out loudly.

Cao Huan slowly opened his eyes and glanced at Cao Zhen weakly: "Retreat, retreat, retreat to Tongguan, tell Cao Shuai, go, go immediately!"

"Uncle!" Cao Zhen looked at the blood that kept gushing out of his fingers, "You will be fine, doctor, doctor!"

Cao Huan suddenly reached out, grabbed Cao Zhen's arm, used all his strength, and shouted, "Let's go quickly!" He roared his last sentence with his last sentence. Cao Huan's head tilted to the side, and the spirit in his eyes quickly disappeared.

Cao Zhen slowly put Cao Huan on the ground and stood up in a daze.

Above the city wall, there has been a Shura hell.

Ten flowering bullets all fell on the left and right of the city tower, but this place was the place where the soldiers were most concentrated. There were no more soldiers standing there, some of them losing their heads, some without arms, and some without any scars, but their mouths and noses kept gushing out with blood.

Even the rest were still standing there in a daze at this moment, and some even panickedly shouted and ran around on the city wall.

There was another loud noise from afar. Cao Zhen was so excited that he rolled on the ground, squatted down against the wall, picked up a large shield on the ground, and covered himself tightly.

"Rise the shield, raise the shield!" He yelled loudly, hiding behind the shield.

The loud sound kept ringing above the city wall. This time, it was no longer shooting at the place that had just been bombed, but began to shoot at both sides.

After Cao Zhen walked out of the shield, he saw his soldiers falling down one after another. He saw some people flying up like birds and falling heavily under the city. With a bang, something hit his shield. Cao Zhen moved the shield away and stared at the broken hand that fell in front of him.

In that hand, a knife was still tightly held.

Not only Cao Zhen on the city, but also Shi Zhuang and You Yong under the city. They saw the Liang soldiers who were knocked down like a destruction on the top of the city from the monocular telescope. They saw the city tower of Jindou Pass that was razed to the ground in a very short time, and saw the battlements that were shaken.

Is this something that Li Xiang said slightly better than garbage?

The two looked at each other, and Shi Zhuang didn't say a word, turned around and walked backwards.

You Yong took a look at Zhu Yi's fat figure again, a flattering smile appeared on his face, and he leaned over.

"Brother Zhu, Deputy Supervisor Zhu."

"What's the matter?" Zhu Yiheng glanced at him.

"This cannon is very good! Can you have a few more rounds? Shi Zhuang will launch an attack soon." You Yong said. "It would be even better if you can lower the city wall a little longer. This damn Jindou Pass was completely made of stones. The catapult has not had much effect on him, but this cannon has a very good effect!"

"Replace solid bullets! Bang the wall! Aim at a distance of about twenty feet and hit me with three rounds!" Zhu Yi shouted loudly.

"Abide by the order!"

You Yong looked at Shi Zhuang, who was already rectifying the formation behind him, turned around and watched the gunners start to control the artillery with concentration. This time, he did not forget to block his ears with his fingers.

"Is the effect okay?" Zhu Yi was a little proud.

"It's so good." You Yong nodded repeatedly: "Such a good thing should be distributed to the army earlier."

After hearing what You Yong said, Zhu Yi sighed: "Li Xiang said that the cannons are too heavy and not easy to carry. If we cannot reduce the weight of the cannons to less than 2,000 kilograms, we will not consider distributing them to the army for the time being. We will prepare to distribute them to the navy first and let the navy officers and soldiers practice."

"We don't think it's heavy, we don't think it's heavy!" You Yong shook his head repeatedly. What a joke. Such a fierce thing is not bad, even if it's heavier, it's nothing more than a few mules and horses, and more manpower. In the future, whether it's to attack Chang'an or to the south, there are cities everywhere, and dangerous passes everywhere. With this thing, all the cities that are as solid as a city will be blown into pieces. "Li Xiang cannot be too partial. The navy has always been the flesh of Li Xiang's heart, but it's up to us to the land to attack the city and plunder the land! I'll give Li Xiang a letter, we want to be more equipment. I also want to write a letter to the generals of other guards, so that everyone can write a letter to Li Xiang together."

"It may not be possible." Zhu Yi poured cold water on him, "Li Xiang said that the south is not as difficult as the north, the roads are more difficult to walk, and the water nets are denser. Such a heavy thing is not suitable for field battles, and it is only suitable for siege. Therefore, General You wanted to distribute a large amount to the army, but Li Xiang would never agree."

Amid the discussion between the two, rounds of artillery sounded continuously, and the siege troops commanded by Shi Zhuang also began to carry the ladder and rush towards Jindou Pass with shouts.

The Jin Dang Pass was broken.

Cao Zhen, with the remnants of defeated soldiers, retreated back to Tongguan City in a panic.

After a full month of troops entering Tongguan, the Tang army finally began to face the city of Tongguan.

"New weapon?" Cao Xuan looked at the armor taken off Cao Huan, and looked at the broken iron pieces embedded on the iron armor, and was speechless for a long time.

"The latest iron balls that fell had exploded violently after they landed, and the whole iron ball exploded." Cao Zhen, who was covered in dirt and covered in blood, still did not come back to his senses until this time. He was still scared and said with a trembling voice, "This caused great damage to our soldiers. Moreover, these things were shot from two miles away, and we had no room for fighting back. The iron balls shot from behind no longer exploded, but our city walls were like tofu in front of these iron balls, and Tang Jun followed behind and rushed in through these gaps."

Cao Xuan's eyes fell on the iron ball the size of a sea bowl brought back by Cao Zhen. The round iron ball was quietly staying on the table at this time, without any threat.

He reached out his hands and moved the iron ball up. It was extremely heavy and was cast from all iron.

"Ten days, I'm afraid we can't hold on for ten days." Cao Xuan sighed. "You go down and rest for one night. Tomorrow, take your subordinates to escort the supplies first!"

"Father, I'll stay here to help you!"

Cao Xuan shook his head: "Your subordinates can no longer go to the battlefield in a short period of time, and we must first remove a large amount of supplies."

"Return to Chang'an?"

"No, Your Majesty has given up Chang'an. At this moment, Your Majesty is already in the Qinling Mountains. After we give up Tongguan, we can only escape into the Qinling Mountains. However, when entering the Qinling Mountains at this time, materials are absolutely indispensable. So you go first, I will block for a few days, and then come."

"Master, can you block it?" Looking at the dark iron ball on the table, Cao Zhen's eyes showed fear.

"Since you know the other party's secret weapon, you can always come up with some solutions." Cao Xuan said: "It can still be blocked in a few days."

After winning the Jindou Pass, You Yong and Shi Zhuang were very happy. The most important reason why Tongguan was difficult to fight was because of the existence of Jindou Pass. Now that Jindou Pass has fallen, it can be said that the difficulty of attacking Tongguan has immediately decreased by several levels.

"Continue to bombard them with guns." You Yong looked at Zhu Yi and said relaxedly.

"This time, I'm afraid it's not that easy." Shi Zhuang smiled and shook his head; "Jindu Pass is small, the place is narrow, and the function of artillery is very obvious, but Tongguan is a big city, with all kinds of Wengcheng and other facilities. If the opponent has learned the lessons from Jindu Pass, he will definitely be able to come up with some solutions."

"So what? I'll hit him for a while. Even if the two sides fight together, are we afraid of him?" You Yong said with a smile.

As he was about to discuss it, an officer walked in and said, "The two generals and the inner guards have sent emergency information, which is about Chang'an."
