The catapult is far from being able to accurately control landing like the cannons in later generations. It is definitely not easy to accurately land on the city two feet wide at a distance of 250 steps. Only 30% of the 100 thunders fell on the city, and other thunderstorms either hit the city wall, or crossed the city and fell into the city.

The thunder on the city wall that lands on the city wall did not explode in time. There is no technology to control the explosion point. It is determined entirely by the experience of the gunpowder. The fuse used by the thunder created by the Song army is three feet standard, of which about one foot is inside the thunder body and the other two feet outside. On the eve of the decision of a certain battle, the gunpowder will make a launch scale mark on the fuse. When it is burned to this scale, it can be fired, which can basically ensure that it will not explode in advance or delay the explosion for too long.

But this trick is the patent of the Song army. Currently, only five gunpowder craftsmen in the Song army can make accurate judgments. These five gunpowder craftsmen are currently in the Jingzhao army, and the Jin soldiers are completely decided by the launcher themselves and have no precise control. The result can be imagined that all the thirty thunders that hit the city did not fall to the ground and explode, but rushed down the city and fell into the deep pit in the city, and exploded in the deep pit.

An explosion sound broke out outside and inside the city at the same time, like thunder, bursting smoke filled the air, and before the smoke was dissipated, the second round of thunder was launched again. The Song army on the top of the city covered his ears tightly, lay under the battlements, waiting for the Jin soldiers to end their power.

This time, the Jin soldiers brought 800 captured Song army thunders, plus the original 200 more than 200. The Jin soldiers had more than 1,000 sky-shaking thunders in their hands, but they could not withstand the Jin soldiers' squandering. One round of launching was consumed, and one thousand sky-shaking thunders were only enough to launch five rounds.

Wanyan Chang also understood this, so after two rounds of explosion, he ordered two thousand soldiers to push the siege cars to attack the city gate, preparing to take advantage of the opportunity to suppress the Song army and use the siege ram to break the city gate.

A siege car was pushed and pulled by the soldiers and rumbled towards the city gate. The siege car had eight wheels, four on both sides, and a ceiling above. A huge siege hammer was hung with iron chains on the thick wooden frame. The hammer body was three meters long and was made of a thousand-year-old giant wood. The hammer head was filled with pig iron, and the impact force was particularly strong. If it hit the door, it would have tens of thousands of pounds of force. Even the strongest city gate would be knocked open.

At this time, the Jin soldiers launched a third attack on the city head, and the siege vehicles also advanced rapidly, only thirty steps away from the city gate. The suspension bridge in front had been blown up, and the moat was formed with a thick ice layer. The siege vehicles accelerated and drove upwards to the ice layer of the moat.

At this moment, the Song soldiers on the top of the city threw a few torches in front of the city gate. The moat was ignited within fifty steps, and the flames soared into the air, and the fire burned rapidly. In order to prevent the Jin soldiers from taking the opportunity to hit the city gate with a siege ram, the Song army buried the turbulent oil in advance. The siege cars and the surrounding Jin soldiers immediately fell into the sea of ​​fire.

‘Boom! Boom!’ Two giant thunders buried underground exploded. The huge shock wave blew the siege cars into two pieces and flew several feet away. Before the two thousand soldiers around had broken free from the flames, they all died in the violent explosion of the giant thunders.

Just then, the Jin soldiers launched the fourth round of thunder attacks. After a series of explosions in the city, the battlefield became completely quiet, and only thick smoke was floating above the city.

The smoke of gunpowder had dissipated, and a large pit appeared about seventy steps in front of the city gate. Both sides of the pit were covered with broken bodies, blood stained the soil, and the base of the huge siege car was blown to pieces, facing the sky, and the siege hammer was thrown aside, crushing dozens of soldiers into meat pie.

Although there were four rounds of bombardment of the sky-death thunder, Wei Ran still stood in Taiyuan City, with eight hundred sky-death thunders throwing at the top of the city, but less than ten exploded on the top of the city, and dozens of Song soldiers were injured.

But the Jin soldiers also gained something, that is, almost half of the trenchers on the top of the city were damaged and needed to be repaired before they could be used. The two towers were blown to pieces and disappeared on the tower. The city was riddled with holes within a hundred steps from the city wall, and the soil was blown everywhere, and the deep pit was covered with iron sheets of shells.

The Jin soldiers did not launch the fifth round of thunder projection, and he only had less than 300 thunders left, so he did not dare to waste it any longer.

At this time, the Jin soldiers replaced them with huge rocks to attack, and the huge rocks were loaded into the catapult, and the black stones were smashed toward the city wall.

Wanyan Chang and Wanyan Zongbi invested 10,000 troops at almost the same time and launched an attack on the city head. The overwhelming soldiers rushed towards the city wall. Wanyan Chang threw in 10,000 Han soldiers mobilized from the south of Hedong Road, and ordered two thousand Jurchen cavalry to be the war-supervising soldiers. Anyone who retreated would be killed immediately.

Wanyan Zongbi invested 10,000 Xi infantrymen. The Xi was fierce and brave, and had a strong combat power. Wanyan Zongbi held his anger and must rush into Taiyuan City before Wanyan Chang.

Without the threat of thunder, the Song army on the city also began to become active. A large number of Song soldiers began to return from Xicheng and Nancheng. The fire cannon and bed crossbow were also pushed back to the city. Li Yanqing ordered the use of the catapult temporarily to stop the use of the stone scattering machine. Before the inspection and repair, he did not allow the soldiers to take risks.

The first to launch the Song army's crossbows, four-foot-long crossbows, shot strongly at the enemy's catapult. The large crossbow was bandaged with gunpowder tubes and constantly exploded around the catapult. Although this gunpowder tube was only equivalent to a large firecracker, it was mixed with a lot of sharp iron sheets. The belt or throwing rod of the catapult was hit by the iron sheet and broke, which could easily lead to the destruction of the catapult.

On the head of Dongcheng, two hundred large crossbow arrows were shot out from the bed crossbow, and shot at one hundred huge catapults. After a round of arrows, the results began to appear. Five catapults collapsed, and then the second round of large crossbow arrows were shot out again.

Li Yanqing was standing in the north city at this time, staring at the 10,000 Jin soldiers who were coming from the sky with cold eyes. He turned around and shouted, "Arrow ready!"

Five thousand archers squatted on the city wall, pulled out their big bow, and the cold arrow tip was slightly tilted upward at a thirty-degree angle. Li Yanqing gave the order, "Shoot!"

The sound of clappers sounded, and five thousand soldiers and arrows rose into the air, drawing a beautiful parabola, shooting towards the Jin soldiers below like locusts, and the Jin soldiers raised their shields to greet them, but the powerful penetrating arrows also shot through the shields of countless soldiers. The soldiers in front screamed and fell down, but the soldiers behind did not stop and continued to rush forward.

"Prepare to put it!"

The second round of soldiers' arrows fell like raindrops, and the soldiers once again fell on their backs.

At the same time, the situation also occurred in Dongcheng, but the soldiers' reactions were very different. Ten thousand Han troops were unwilling to go to the battlefield, and their morale was very low. They were also poor in equipment. Most of the soldiers were not equipped with shields. When the arrows on the top of the city fell like hail raindrops, rows of soldiers fell to the ground. The soldiers behind were frightened and fled.

Wanyan Chang had long known that the morale of the Han soldiers was sluggish, but he needed this army to attract the firepower of the Song army as a vanguard to cover his real actions. He was more experienced than Wanyan Zongbing and knew the difficulty of siege. His purpose was to take the opportunity to use the thunder to explode the city gate in the fierce battle.

After he rushed to the army, he sent two thousand Jurchen cavalry to supervise the battle behind. At this time, the first group of soldiers turned around and fled back. They encountered the supervising army that was ten times more fierce than the Rain of Arrow. The two thousand supervising cavalry shouted loudly, and the sword in their hands slashed at the fleeing soldiers without hesitation. In a moment, hundreds of people were killed. The Han soldiers were so scared that they had to turn around and continue to rush towards the city wall.

On the top of the city, Wang Gui also cursed softly. These soldiers were willing to be alien hawks and dogs, and they deserved to die. At this time, the Jin soldiers who were sieging the city had already reached the city, and the catapults in the distance also stopped attacking. Wang Gui immediately ordered: "Fire artillery!"

The yellow flag waved, and the soldiers lit the fuse. When it burned to the red scale, the two hundred artillery on the top of the city fired almost at the same time, shooting two hundred thunders down the city. The thunders exploded above their heads without falling to the ground. These Han soldiers did not undergo training to prevent thunders. After the thunders exploded, dense shrapnel burst into all directions, and there were countless poisoned iron sheets inside. They screamed in a row. Almost none of the soldiers who had 50 steps to within a hundred steps under the city wall were spared, and they were more or less hit by the iron sheets, with more than two thousand casualties.

Wanyan Chang was furious and threw in another five thousand Han soldiers, shouting: "Beat the drums and urge the battle!"

‘Dong!Dong!Dong!’

The drums were loud, and the Han soldiers on the battlefield were forced to go to the top of the city, and they were greeted by the ruthless soldiers and arrows and the killing of thunder.

During the chaos, thirty Khitan soldiers were running towards the city gate with the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder are immediately discovered by Wang Gui's suggestion. According to Wang Gui, Li Yanqing set up a thousand thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder are not to shoot arrows to attack the enemy, nor to stand on the top of the city to fight with the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder and the thunder are responsible for observing and preventing

Not only are there hundreds of thunder-viewing players in the East City, but also in the North City. The city gate is their key target for defense. Thirty enemy troops under the city run wildly towards the city gate abnormally, holding black thunder like winter melon in their arms, of course they can't escape the gaze of those who are interested.

Before the thirty people approached the city gate, hundreds of soldiers raised crossbow arrows and shot them. The thirty enemy troops were caught off guard and were shot down by arrows. A few thunders also escaped and rolled onto the ice of the moat. Five soldiers behind rushed forward and picked up the thunder and continued to rush forward.

Just as a few people ran to the city, hundreds of barrels of water poured down the city, several soldiers were immediately poured like chickens, and the thunder in their hands was soaked, and the fuse could not be ignited anymore. Several soldiers threw away the thunder in despair, turned around and ran away, but they ran for a few steps, and arrows shot from behind. Five soldiers screamed and were shot down and killed immediately.
