The Song army is no stranger to Chaoche, whether it is the Taiyuan Defensive Battle or the first Tokyo Defensive Battle, the Chaoche has brought a huge threat to the soldiers defending the city, and the Jin soldiers have attacked the city several times are the achievements of the Chaoche.

Li Yanqing also attaches great importance to Jin Bing's nest car, and he knows very well that when the flying fire and thunder become a sharp weapon to deal with the siege ladder, the nest car will become the greatest hope and sharpest weapon for Jin soldiers to capture the capital.

But just as a spear is bound to have a strong shield, Li Yanqing has suffered a lot of losses from the nest car several times, and he also attaches great importance to the method of defending the nest car, for this reason, he offered a reward of 500 taels of silver in the Firearms Bureau to develop an effective means of defending the nest car.

Just three days after Li Yanqing put out the reward, a firearms craftsman surnamed Kong thought of a wonderful way to deal with the nest car.

The firearms craftsman's idea came from the Tribulus Thorn, which was an effective means of dealing with enemy cavalry, long spikes pierced into the horse's hooves, causing the horse to suffer so much pain that it lost the ability to run, and the Sky Shaking Thunder could easily blow up the nest car, but the nest car was fully enclosed when it was traveling, and only when the bridge was lowered and put up on the city, the nest car would show a large opening, but by then it was often too late.

Therefore, as long as the sky-shaking thunder can be attached to the nest car and explode, it can cause heavy damage to the nest car, which is the consensus of all firearmsmen, but how to make the sky-shaking thunder can be attached to the nest car and explode, has become the key to the development of the special sky-shaking thunder for breaking the nest.

The firesmith surnamed Kong designed a kind of tribulus terrestris thunderbolt, mounted the tribulus terrestris thorn on the shell of the earth-shaking thunder, and launched it with a cannon, within fifty steps, the tribulus terrestris thunder could hit the nest car, and at the same time, a few inches long tribulus terrestris thorn was nailed to the giant wood outside the nest car, and the earth-shaking thunder could be close to the nest car and exploded.

This plan was simple and reliable, and was approved by the military, and the firesmith surnamed Kong won a reward of five hundred taels of silver, and at the same time was promoted to become a first-class firearms craftsman of the Firearms Bureau.

Li Yanqing gave an order, hundreds of militiamen carried hundreds of boxes of tribulus terrestris earth-shaking thunder from the city, and the earth-shaking thunder is now placed in a wooden box, two earth-shaking thunders are placed in a wooden box, and a layer of fireproof oilcloth is wrapped outside the wooden box, so that even if the earth-shaking thunder is placed at the head of the city, it is not afraid of enemy fire.

Thirteen nest carts were getting closer and closer to the city walls, each propelled by two hundred soldiers and pulled by ten oxen, which were blindfolded and deaf and unaffected by the fighting outside.

The Song army's earth-shattering thunder continued to explode around the nest car, and one sky-shaking rolled into the lower end of the nest car, and exploded violently, two huge wheels were blown away, the nest car overturned to the side, and twenty heads were affected by the shock wave and iron plates, all of them were killed, and nearly half of the two hundred soldiers were killed and wounded.

At this time, the other two were also blown up by the earth-shattering lightning, but there were still ten nest carts within fifty paces, close to the moat, the moat had been put on the plank, the nest cart of the healthy ox had been taken away, and the soldiers pushed it from behind, so that the nest cart began to approach the moat little by little.

The forty fire cannons on the head of the city began to change the tribulus terrestris thunder, the fire cannon is a giant crossbow, about one zhang three feet long, four feet wide, before the Song Dynasty called the stone cannon, used to launch boulders, after the large-scale appearance of firearms in the Song Dynasty, the stone cannon was renamed the fire cannon, became a powerful weapon for launching thunderbolts, and now the thunderbolt mines are upgraded to earth-shaking thunder, but the fire cannons have not changed.

Three soldiers pushed the winch to wind up, loaded the launch slot with tribulus terrestris thunder, one soldier lit the fire rope, and when the fire rope burned to the red line, one knocked down the hanging knife, only to hear 'Bang! With a bang, the Tribulus Terrestris Earthquake Thunder was ejected out, and it shot strongly towards the nest car fifty steps away, and the Sky Shaking Thunder accurately smashed on the nest car, with the help of a strong impact, a row of three sharp thistle thorns were nailed into the wood, and the city soldiers covered their ears and squatted down.

Hearing an earth-shattering explosion, debris was scattered, thick smoke was filled, mixed with terrible screams, and when the explosion gradually subsided, the soldiers slowly raised their heads, only to see that only half of the nest car fifty paces away was left, and the ground was full of broken wood and mutilated corpses, and the soldiers suddenly jumped up and cheered loudly.

Tribulus terrestris thunderbolts are indeed very practical and effective, and the other nine nest cars have also been severely damaged, or blown up, or overturned, and none of them can cross the moat.

There was no nest car, Wanyan Lou Room once again invested 30,000 soldiers, ordered to attack the city at all costs, the golden soldiers on the battlefield have reached 70,000, more than 1,400 siege ladders have all been put into battle, Li Yanqing also ordered all the soldiers of the New Northern Army to participate in the battle, the soldiers who participated in the battle in the north city reached 30,000, and the earth-shaking thunder, iron fire thunder, and flying fire thunder were used in turn.

The two sides killed the red eyes, the battlefield was filled with gunsmoke, the blood flowed like a river, the casualties on both sides were very heavy, the city was full of corpses, the Bohai Navy 20,000 gold soldiers had been killed, there was still a steady stream of Jurchens, Khitans bravely attacked the city, and the Song army on the city was desperately resisting, the forbidden army was killed on the top of the box army, the box army was killed by the reserve militia and then on top, the Jin soldiers attacked the city seven times before and after, and were killed by the Song army seven times.

The battle lasted from early morning to dusk, and the two sides fought in the dark, with huge casualties, but the walls of Tokyo still stood and were never captured by the Jin soldiers.

When twilight fell, the bell of the Jin soldiers' retreat finally rang, and the exhausted Jin soldiers finally had to retreat, they withdrew like a tide, leaving behind the corpses all over the ground, the second battle of Tokyo, the Jin soldiers lost more than 40,000 people, and the Song army also killed more than 23,000 people, the New Taipei Army was killed and wounded nearly half, and the militia and the forbidden army in front of the palace were also killed and wounded.

When the Jin soldiers were forced to withdraw, the soldiers at the head of the city hugged each other excitedly, their voices were hoarse and could not shout, but they shed tears of victory, and hundreds of thousands of people waiting in the city heard that the Jin soldiers were defeated, and the whole city cheered, and the cheers suddenly resounded in the sky.

..........

But the war is not over, the 30,000 cavalry led by Wanyan Zonghan are still waiting outside the Xicheng, the wall of the Xicheng has not yet been demolished, and the wall of more than ten miles long covers their tracks, and they are patiently waiting for the success of the last secret operation of the Jin soldiers.

The soldiers at the head of the city were extremely busy, carrying corpses, bandaging wounded soldiers, cleaning up sediment, and transporting supplies, Li Yanqing listened to Zhang Hu's report in the old Fengqiumen tower, and when Zhang Hu led 500 soldiers down to the city to clean up the wounded soldiers on the battlefield, he received an important piece of information, and when a wounded and unable to evacuate the Yandi Han Jin soldiers begged them to spare their lives, he revealed an extremely important news to them.

"I think the news should be accurate, the plague has broken out in the Golden Soldier Battalion!"

Of course, Li Yanqing also knew about Yan Qing's plan, but the stakes were very high, and Li Yanqing could not draw conclusions based on the confessions of just one or two soldiers.

He pondered for a moment and said: "I also believe that the information about the plague in the Jin camp is true, which is in line with our plan, and now I am more concerned about the severity of the plague, which is the key to whether the Jin soldiers withdraw or not!" ”

"Qi Yu is all in charge, and more than 20 lightly injured Jin soldiers have been arrested, and the lowly position can be interrogated separately, if the confessions of more than 20 people are consistent, it can basically be judged."

Li Yanqing nodded, "This method is okay, where are they now?" ”

"Currently in Wengcheng, I heard that there was a plague outbreak in Jinying, and I didn't dare to take them into the city."

"Go and interrogate! After the interrogation, all the brothers who came into contact with Jin Bing were to be quarantined for a few days, including you, just in case, understand? ”

"Humble duty understands!"

Li Yanqing sent someone to find Cao Sheng again and said to him: "You go to the city to collect quicklime and fire oil, as many as you want, gather them all, I have a great use, and go to tell the people of the city that there is a plague outbreak in Jinying, and ask the people of the city to pay attention to prevention." ”

"Obey the order!"

Cao Sheng hurriedly went with a salute, Li Yanqing walked out of the city tower with his hands in his hand, and at this time, Zhang Qing hurriedly came, "Dutong, there is a strange thing." ”

"What's weird?" Li Yanqing asked.

"Suddenly the water to the north and east of the moat disappeared, and there was still a little to the west and south."

Li Yanqing was stunned, "When did it happen?" ”

"I asked, it should be that the water level began to drop in the afternoon, and the water disappeared just now, and it seems to have been led away."

Li Yanqing frowned, the inner city moat is connected to the Bianhe River, is the Bianhe River cut off?

"What is the situation in Bianhe?"

"The water level of the Bianhe River has also dropped a lot, and it is only half of the morning, and it is no longer possible to return to the northern moat."

The topography of Bianliang is high in the northwest and low in the southeast, and if the Bianhe River is cut off, the water to the north and west of the moat will indeed flow away quickly.

"General Zhang, do you think that in addition to the Bianhe River being cut off, are there any other aspects that cause the moat to run out of water?"

Zhang Qing shook his head, "I can't think of any other possibility, even if it is a subsidence, the water of the Bianhe River will still flow continuously, and it will not lead to a break." ”

Li Yanqing thinks the same, but what does it mean that Jin Bing cut off the Bianhe River?

Flooded Bianliang? Li Yanqing shook his head secretly, it is impossible in the terrain, Bianliang is in a high place, not in a depression, and it can't flood the city at all.

Is it trying to cover something? What are the consequences of the absence of water in the moat, along the moat canal into the city? It's a joke.

"Into the city?"

A thought flashed through Li Yanqing's mind like lightning, and he suddenly understood.
