Xiong Jing did not understand the history of the development of infantry tactics. In the era of cold weapons, and even in the era of mixed use of cold and hot weapons, infantry was all square formation tactics, except for the Roman shield formation. After the Romans, line-type tactics commonly used by Roman legions appeared in the 17th and 18th century, and eventually became a queue and shot. Later, due to the too dense queue, it was changed to columns in the 19th century (especially during attack) and focused on scattering, but line-type tactics still existed. It was not until the beginning of the 20th century that the Boer people did not line up to fight in the Boer War, and scattering tactics gradually became the mainstream.

The tactics of the square formation are not as flexible as line tactics and straggler tactics. The phalanx can only move forward or backward, and must not go left or right at will. That is why Lian Po said, 'The formation is like playing chess, and you must not regret the move'. At this time, the left and right armies had already lined up. Now they had to transfer these large square formations to the central army and launch an attack. This is simply something that cannot be done. Lian Po originally wanted to answer: "It has been like this since ancient times." Unexpectedly, the sound of gongs suddenly came, and Xiang Yan ordered the central army to retreat immediately.

The sound of the gong surprised Xiong Jing on the chariot, and also surprised Gong Jia of the Chu army in the fight. The cavalry blades made of Juti were extremely sharp, with spears, beryllium spears, and wooden armor shields. They were all cut off. Gong Jia was slaughtering Qin army soldiers and crossbowmen like vegetables and melons, but he didn't expect that the general would actually retreat by himself.

"Retreat, retreat quickly! The spearman is in front, the spearman is in front." The last soldier, Chang Zhuang Quji, was stunned and ordered the Gong Jia to retreat. The only few remaining spearmen in the back row were adjusted up and began to retreat quickly. The Gong Jia was like this, and the sanitation soldiers immediately retreated when they heard the sound of the gong.

The Chu army retreated rapidly, and the Qin army's soldiers who had just arrived at the melee rushed forward. Under their leadership, they were disbanded, and the Rui soldiers who were fighting each other re-arrayed and advanced rapidly with the rear army.

The Chu army retreated and the Qin army advanced. The battle line between the two armies changed from arches to straight lines, and from straight lines to concave. After the previous battle, the Chu army, which had a twenty-row line in depth, was not only chaotic, but also extremely thin in depth. In order not to allow the Qin army to break through the array, even if the shogunate no longer beat the gong, they could only continue to retreat and relieve the Qin army's advance through distance.

Although we knew that we had to retreat to get the Qin army into our pockets, the Qin army rushed forward too hard, and under their attack, the retreat almost led to a collapse. The counterattack organized by each division was soon defeated by the Qin army, and the Qin army was pushed faster.

"Why don't you send Youque to reinforce?! Xiang Yan..." The Pi Zhou of Xiyang general Zeng Xia was already crooked. He also organized several retaliation, but he soon failed. He looked forward to the rear, but saw Youque Ji still, so he started to scold Xiang Yan while sending someone to ask for help.

Zeng Xia was like this, and even if the other divisions did not scold Xiang Yan, they were still full of anger. Their army had been fighting for a long time, and they still had some strength when they retaliated just now. Now the sound of the gongs, the energy they were holding dissipated, which could resist the Qin army's new force that had just come on the field.

"Quick! Quick! Very urgent, please send troops to rescue the general quickly." The messengers were sent to the shogunate. In addition to the words of asking for help, there were also words of breaking the formation. For a moment, the shogunate was full of calls from the people who were asking for help from each division.

"Our general asks the general to send troops quickly. If he doesn't send troops, his army will be defeated." Xiang Yan was not there, and there is only military Sima Peng Zong in the shogunate.

"The general has his own qualities." Peng Zongren here is to comfort the soldiers of each division. "Our army retreats and the enemy is in a vain. This matter has been discussed with the generals of each division, please wait..."

"Sima of the army, our army is retreating, but the Qin people chased me hard, and if they don't send troops, the army will collapse." Zeng Yin, who was able to speak and said, complained directly. Not only did the Xiyang army do this, but the other divisions were the same. After he said this, he echoed.

"If the army formation is defeated, the entire army will be destroyed!" Peng Zong was not in a hurry, but General Xiang Yan was not in a hurry. "You can go back quickly and tell each general that you must not collapse."

After Peng Zong finished speaking, he was about to leave the mansion to find Xiang Yan, but Zeng Yin grabbed him, "Sima of the Army, when will Youque send troops?"

"Youque needs to send troops to the general. How can I find the general to send troops?" He pulled hard and hurried out of the mansion. As soon as he left, the crowd stared at each other, and they were not going, and they were not going, and they finally returned to the divisions to report the news.

"General..." Xiang Yan was already above the Chaoche at this time. He had to see the situation of the two armies clearly before he could decide the final deployment of Youque. The Chaoche rose to the highest level, and stood at this height, and the battle line between the two armies was clear at a glance. Both left and right armies were not the main attack direction of the Qin army. The Qin army in these two places had weak forces, and although the battle was fierce, it could never break through its own array.

The danger is the central army. The 4,000-line wide central army was very thin after a long battle. The place where the fighting and the impact was fierce, now only three or five disciples were left. Many divisions had no array, and only the bloody disciples leaned on the last bravery to form a row to resist the Qin army. However, the mobs could not stop the Qin army with strict array. As long as the Qin army advanced slowly, they could force them to retreat repeatedly. This was a sign that the formation was about to break. In this case, not to mention others, Xiang Yan, who was familiar with his friend, was also worried.

"How many steps have our army retreated?" Xiang Yan turned his head and asked the lookout hand beside him. At this time, the two armies' fronts were blurred, and he could not see how many steps his array had retreated.

"Report to General, our army has retreated thirty-five steps." The lookout hand replied. He had long remembered the original array line.

"Thirty-five steps..." Xiang Yan felt her heart trembling, as if she was about to jump out of her chest.

"General, our army seems to be unable to support it." The status of the lookout hand, but his army was shaky, so he risked his life to remind him.

"It is difficult to support and must support it. You must retreat to forty steps before you can..." Xiang Yan murmured to himself, and the Lu Li mirror in his hand was aimed at the rear of the Qin army's array again. At this time, the Qin army reinforcements had already broken into the early array of the Chu army, and there was no dust behind them. Looking closely, the Qin army's rear army was still on standby, which immediately made him wonder: Could it be that the Qin army's rear army had not all been put into the battlefield?

"The Jing people have been exhausted and they are defeated step by step. If the formation breaks through in an instant, our army will be victorious!" Using the Lu Lijing of Meng Wu, the guard Sima Kong, saw that his flag was advancing, and the Chu army retreated in a hurry, and could not help but say this.

"The Sikong Guardian Army is wrong." Meng Wu swept away his previous gloomyness and said with a smile: "I think that Xiang Yan is also a famous general of the Jing people. He can just join the rear army to defeat our central army, but unfortunately he missed the opportunity. At this time, the Jing people's energy was discharged and their morale fell, and they could no longer defeat me. However, the subsequent army is still there, and it is not easy for our army to break the Jing people's formation."

His side had indeed passed a narrow pass. Sikong Ma knew this. He asked curiously: "The Jing people are brave, what should the general win?"

"Of course, it is to defeat the central army of the Jing people." Through the command just now, Meng Wu felt that Xiang Yan had no experience in commanding the war, so he was quite content. At this time, one by one, the military chariots of the army were heading towards the formation. According to past experience, any array could not resist the rapid chariots of the army. As soon as the military chariots came out, the Jing people were about to be defeated.

"General, the Qin army is coming in a team." The Qin army's chariots came out, and the lookout immediately reported it. At this time, Xiang Yan was still counting the retreat steps after his army lost its strength.

"Red chariot?" Xiang Yan also saw the Qin army's chariots. Unlike the normal chariot array, these chariots not only walked in groups, but were not soldiers but cavalry. There were about 200 chariots, and they formed an array to slowly advance towards the central army. This reminded him of the last warning from the Grand Sima: the Qin army had the skill of breaking the formation.

The peace lasted for decades, especially the Qin army had not fought for a long time, and the new tactics of the Chu army were completely unaware of. Fortunately, the Grand Sima Mansion came to warn him, otherwise Xiang Yan would not know what these chariots were going to do.

"Tell the artillery to immediately prepare to sprinkle thorns." Xiang Yan's order was written on the wooden tablet, and he threw it off the nest cart and quickly passed it to the trencher.

Yin Dao, who was already hoarse in his voice, was responsible for commanding the stone-tower army. Although he was a civil servant, many of the Chu officials from hundreds of years ago did not distinguish between civil and military affairs, so many of his ancestors died in the battlefield. In this battle, being able to command a weapon like a stone-tower was enough for him to record a record in his family's history, but the fire bomb that was shot just now shocked his soul. Fortunately, the king was fine, otherwise he would have to rely on his sword to apologize.

"General ordered our troops to shoot thorns?" Looking at the orders and talismans on the wooden tablet, Gong Yindao's face was full of disgrace.

"That's right. At dawn, the general sent me to inform Dr. Yin to prepare the thorns. Doctor Yin had forgotten?" The military officer came once in the morning, so he reminded Dr. Yin Dao.

"I will never forget." Gong Yindao certainly remembered what happened in the morning. "However, then..." Gong Yindao's hands and feet were cold when he thought of the fire bullet that had fired just now. "My unit is too close to the military formation, if it is shot missed..."

"Doctor Yin of Gong, thorns are not fire bombs, they are not bad even if they are scattered on our soldiers." The military officer of course knew Gong Yindao's concerns. He added: "The king is in a military chariot, and the chariot has a strong shield, so he should be bad."

When he heard about the king, Gong Yindao was shocked and even burped, which was frightened. He waved his hand and said, "It's not impossible to be too close. Please ask the general to go to me for two thousand people. You must also move out of the formation and the catapult can retreat."

"Retreat?" The military officer looked at the catapult that was firing fire bombs. The loaders were fine, but the strong men who were turning the disk were exhausted and panting. Although they changed people from time to time, they had been fighting until now. After every round they stepped, they could not get up after coming out.

"You need to retreat. Go quickly." Gong Yindao was impatient with him and sent him away. In addition to the longest range, the catapult also has the shortest range. The ten-ton configuration is equipped with a minimum range of about 80 steps. If it is short, the firing bullets will appear like the one just now. So now the firing bullets can only be fired outside the Chu army's array line. However, now the Chu army retreats and the Qin army follows up. Even if Gong Yindao ordered people to move the catapult direction to increase the range of the diagonal shooting, the firing bullets would not hurt the Qin army that broke into the his army's array.
