Due to the need to cool the barrel after the artillery was fired continuously for a period of time, and because the ammunition was too expensive, after destroying the siege weapons of the Mongol army, the Thunderbolt warships no longer concentrated fire in a salvo, but were fired by the warships of the six naval battalions in turn. Although this method of firepower firing is resource-saving and cost-effective, the firepower blockade formed is not violent, but only weakens the offensive of the Mongolian army, and does not prevent waves of Mongolian soldiers from rushing forward. Although the Banshu army was good at fighting and had plenty of grenades, after a long period of high-intensity fighting, their physical strength had greatly decreased, otherwise the soldiers were already tired. On the other hand, due to the large number of Mongolian troops, under the wheel tactics, the physical strength of its soldiers is much more abundant. As the battle continued, the physical disparity between the two sides became more and more wide, making the casualty ratio of the two sides closer and closer.

Under Liu Quan's supervision, the new annex army of Shenjian City attacked extremely fiercely, and once broke through more than ten meters into the camp, but was repelled by Yang Wen and his own army. To say that Yang Wen is also very brave in battle, he makes a long knife superb, and every time he swings it, he will reap a human life. Although there were only 100 people on his left and right, the pro-soldiers who were close to him were extremely elite, and they could often knock the Mongol troops back again and again with a single charge. It's just that Liu Quan is also brave and good at fighting, and his army management is also extremely strict, and the defenders of Shenjian City are also very strong under his training. At that moment, Liu Zhengzheng and his men gathered at the west gate of the camp, ready to launch a thunderous blow to crush the defense of the Banzhou soldiers in one fell swoop. At this moment, Yang Wen's armor and beard were covered with mud and blood—the blood of the Mongolian soldiers, and so were the soldiers who were tightly clustered around him.

Just when Liu Cheng was about to give the order to charge, a cronie next to him gently pulled his sleeve, and when he was about to burst out in anger, he saw the cronie's arm pointing to the east gate of the Divine Arm City behind. At this time, the battlefield was full of fires, explosions shook the sky, and shouts of killing came and went, but in this noisy environment, he saw the east gate of the Divine Arm City constantly flickering with firelight, and it seemed that he could faintly hear the sound of explosions and shouts of killing. Just as he was bewildering and hesitating, two lame soldiers were brought in front of him. Under the bright light of the torches, the two soldiers turned pale, and their speech was also slurred, and Liu Cheng finally heard clearly from their mouths: "The east gate is occupied, and the Divine Arm City has fallen."

Knowing that the lair was raided and the road was raided, Liu Cheng fell into an ice cellar, and his generals and soldiers were also like mourners, and many people even cried in public, because their property and families were in the city. Losing the Divine Arm City means that they have all become lost dogs. Hearing the crying of his subordinates, Liu Quan's heart was even more like a mess, his beloved concubine and the money he had collected over the years were also in the city. It is said that Liu Quan is also a person who has seen strong winds and waves, so he stabilized his mind at the moment, and ordered his subordinates not to cry so as not to disturb the morale of the army, and then sent people to report the news to Niu Lu, and ordered to give up the attack on the Banzhou military camp and prepare to recapture the Shenjian City. Although he had not yet received an order from Niu Xuan to change the direction of his attack, Liu Cheng predicted that he would definitely do so, because the Divine Arm City was too important.

Just as Liu Quan's judgment was, Niu Lin agreed to give up attacking the Banzhou military camp and instead made the recapture of Shenjian City a top priority. In addition to its strategic location, which can cut off the connection between eastern Sichuan and western Sichuan, Shenjian City can also lock the Thunderbolt army from developing from western Sichuan, and can also threaten Chongqing downstream. In addition, Shenjian City, as the governing land of Tongchuan Road Mansion and Luzhou Prefecture, also has a large number of official cadastrals and atlases. The Mongolian army wants to annex and govern Tongchuan Lufu, and these materials are extremely important. Judging from the current battle situation, if the core fortress of Shenjian City is lost, not only will the entire Luzhou Mansion be taken by the Thunderbolt army, but even the more than 10,000 Mongolian troops led by Niu Lin may not be able to retreat in their entirety. In fact, in the battle plan of the Mongolian army, Shenjian City is not only the key to repelling the Thunderbolt army, but also the key to occupying the entire Tongchuan Fu Road.

Knowing that the Divine Arm City was actually lost, Niu Ling's face became extremely distorted under his anger, and for a while he couldn't help but pick up the horsewhip and beat the captain who delivered the letter, causing the unlucky ghost to roll all over the ground. When he was tired of fighting, he put down his horsewhip and began to curse, scolding both the Thunderbolt Army and Liu Quan's incompetence. If it weren't for the fact that Liu Cheng was a general who Kublai Khan personally ordered to ask for help, Niu Lin would definitely kill him for the crime of losing the city to vent his hatred. Anger turned into anger, in the face of this drastic change in the battle situation, he had to adjust the deployment of troops, while Mingjin collected his troops, and ordered Liu Quan to atone for his sins and recapture Shenjian City, and the rest of the Mongolian army prevented the Banzhou army from taking the opportunity to attack; He also sent a messenger back to Jianzhou overnight, asking Liu Heima and Baijianu to continue to send additional troops and horses to support. When he finished giving the order and the Mongolian army began to carry out the order in the chaotic bombardment, the sky was already light and the light rain had stopped.

Another day later, Liu Cheng led his army to begin a counterattack on Shenjian City. As soon as the order to attack was given, hundreds of trebuchets and ballistae outside the east gate opened fire, and for a time stones the size of fists and crossbow arrows the thickness of children's arms flew towards the city wall, and although the momentum was not comparable to the collapse of artillery, it was also very terrifying. The siege weapons of Shenjian City were damaged a lot in the battle with Yu Xing, and later most of them were destroyed by the artillery on the Thunderbolt warships. In fact, these siege equipment and the equipment that was destroyed in the attack on Banzhou military camp last night were all left behind when Yu Xing was defeated and retreated. Because of the narrowness of the Shenarm City, and the fact that Liu Cheng was busy repairing the damaged city gates and city walls after defeating Yu Xing, he had not had time to move them into the city, but the crooked attack came in handy.

There are three city walls at the east gate of the Divine Arm City, and each wall is only forty or fifty meters apart. The Thunderbolt defenders did not guard the first wall, but after the second and third walls. They did not stand on the wall when the crossbow stones were flying, but hid at the base of the wall behind the wall, so they did not suffer many casualties. Except for the first city wall, the city defense facilities at the east gate were not seriously damaged. Although the most vulnerable gates were smashed, they were still unable to pass through because the Thunderbolts had blocked the gates with boulders and logs in advance. The dense ballistae flew in, and the Thunderbolt soldiers were so suppressed that they didn't dare to take the lead, and they could only be beaten but couldn't fight back, which was really too embarrassing. This is simply not very hurtful, and it is extremely insulting. At this moment, the Thunderbolt soldiers in the city began to miss the artillery again. If there were artillery in the city, there would be no chance for the siege equipment to be fired, and it could even be destroyed from a mile away.

Liu Quan's men rushed to the city wall with simple ropes and long ladders, shouting wildly, and they did not wait for the shields and siege vehicles that came slowly behind them. On the one hand, these new annexes are anxious to capture the city of Shenjian in order to save their families and regain their property. On the other hand, it is also because these siege machines will be blocked by the first wall, and they will be useless for capturing the second and third walls defended by the Perak army. Just as they were about to reach the wall, the trebuchets and ballistas finally stopped firing, and the Thunderbolt soldiers hiding at the base of the wall also ran to the defensive position. It is said that the accuracy of these two siege weapons is not high, and if you don't stop shooting, it is easy to accidentally injure friendly soldiers.
