What a tough bone.

Why can the Qin army maintain such a dense rain of arrows under the attack of two hundred stone casters? The Qin army on the city did not seem to be suppressed at all, and the strangest thing is that there are still some reasons for the few counterattacks of the Qin army's Longwu Thunderbolt Fire General cannons. However, according to common sense, in such a fierce siege, the attack of the flying thunder cannons on the top of the Qin army's city should have stronger effect. The flying thunder cannon is a reduced version of the general cannon, which can shoot a twenty-pound bomb bag of 100 steps away. The amount of bombs is one fifteenth of the general cannon and the range is one sixth of the general cannon.

However, this kind of flying thunder cannon is small and flexible, and it can be carried away at will at will. It is loaded and launched quickly, and has the ability to continuously fire. It can project at least twenty explosive packs in one hour. If the Qin army lined up their flying thunder cannons in a row, the fierce firepower could instantly clear all the siege troops.

But in fact, although the Qin army has been using thunder cannons to help defend the city, according to his observation, the Qin army's thunder cannons maintained at the same time, no more than ten thunder cannons were attacked. It seems that the Qin army has set a limit, with a maximum of no more than ten thunder cannons shooting.

According to the hardship he suffered in the past few days, he was quite clear about the Qin army equipment on the city. This kind of flying thunder cannon is actually the best weapon to deal with ants attacking the city. It kills a large piece, especially when it is loaded with a shotgun bag, the gunpowder inside is mixed with iron nails and broken porcelain pieces, which is extremely fierce. Although this shell directly kills not many, the destructive effect is very great. On such a battlefield, a wounded soldier is sometimes equal to a dead person.

The heavy crossbows on the top of their city were definitely the most effective weapons to destroy their stone-capping cannon formation. Their two hundred stone-capping tools were all small stone-capping tools. The range was actually far below the Qin army. Although Yelu Shilu built a short-wall shield array in front of the stone-capping array and immediately transferred after bombardment for a while, every time he shot, the position was still unquestionably exposed. Moreover, in order to maintain the artillery array, Yelu Shilu had to set up an infantry shield array in front of his three artillery arrays that often changed positions.

If the Qin army in the city used their cannons and heavy crossbows to fight back and focus on bombarding their cannon formations, it would cause heavy losses to the coalition forces. But why did the Qin army just use a few big cannons to bombard them, but never use their catapults and crossbows formations?

Could it be that the Qin army was deliberately conserving their strength, or that they had giant cannons, flying thunder cannons, eight-ox crossbows, but there were not enough ordinary catapult cars and heavy crossbows?

Yelu Shilu's eyes narrowed into a slit.

"There is something strange here!" Yelu Shilu turned to Yelu Fenggu and said.

Deputy Commander Yelu Fenggu nodded but said nothing. Yelu Shilu saw it and frowned even more. Fengguzhi's meaning was very clear, and he was also confused like him.

"I heard that the Qin army is very good at building cities. They built a large number of castles in Liaodong, most of which are prism-shaped multi-faceted city walls, allowing the defenders to defend against more enemies with a smaller number. The siege side was hit by multiple faces at the same time. The concave and undulating ridge walls made their firepower cover completely without dead corners. It is said that they can attack with seven times one defense, and insist on the enemy blocking and attacking for at least seven months." Yelu Shilu thoughtfully revealed some of the information collected these days, "It is said that the Qin people's city surface will deliberately tilt inward at some angles."

"Why?"

Yelu Shilu waved and took a shield from the guard behind him. It was a steel shield, a standard Qin army knight shield, which was round and not big, with tiger head patterns on it. The most important thing is that the shield surface was not flat, but was raised outward in a cone shape, and it was not cone-shaped, but divided into eighteen uneven surfaces.

"Did you see this shield? The eighteen sides of this shield surface and this cone shape are not only good-looking. In fact, the biggest advantage of this shield is to defend against arrows. I have tried it. When the arrows shoot on this shield, most of the force can be removed because of the inclination angle and edge surface on this shield surface, causing the arrows to slide away. Even if our strongest warriors hold the best bow and encounter this shield, at most half of them may be able to nail into the shield. The Qinren City surface is designed with an inclination angle, which is the same as this shield, but it is specially designed for preventing the projection.

The stone bombs of stone tools were bombarded. I heard that the walls and the surface of the Qin army in Liaodong were inclined. The Datong city wall was very correct and there was no wall of the tomb-shaped city. But I guess they might have transformed the city surface into an inclination angle. After all, it is not difficult. When defending the city, as long as their soldiers defended against battlements, our stone bombs would have a very small threat to them. After all, it would be nice to throw three of ten stone bombs into the city. If their city surface really had a certain inclination, the effect these three stone bombs would have been less."

Yangu was just a warrior of the Diela tribe, but he was a little stubborn about these civil engineering and other things. Yelu Shilu talked for a long time, and he just understood it a little. But if he had to come up with a solution, it was a bit too extravagant.

"Bang!"

A long battlement arrow hit Yelu Abaoji's birch cowhide shield. The person who shot the archer was obviously a person with great strength. After the arrow was inserted into the shield, the tail of the arrow still shook, which made Abaoji's hand feel sore. At this time, he had no idea who shot the arrow. The soldiers hiding in the rushing car covered with thick sand and raw cowhide had already passed the defensive formations of the city, such as the moat, pits, and pickets that were filled with countless lives in the past few days, rushed to the city. The soldiers lifted the ladder out of the rushing car and leaned against the city wall of Datong. The ladders rose one by one and were directly on the female wall of the urn.

"kill!"

"rush!"

The sound of war drums behind him became more and more anxious. Several officers from Abaoji's guards held a shield, held a knife in their mouths, stared at them with huge eyes, jumped onto the cloud ladder, and climbed towards Yunzhou City. A group of warriors behind them followed closely and followed one after another.

Yelu Abaoji clenched his fists and punched his chest several times, let out a loud roar, and rushed forward with a shield. As soon as he stepped forward, the warriors of various tribes in the guards behind him also rushed up with a scream.

At this time, the city walls of Yunzhou City were full of rising ladders, rows of black gray and white leather robes, as well as rope armor, iron armor, and even half-body armor that had just been peeled off from the Qin army's corpse. The tribal warriors in steel armor held their shields, like a huge colony of ants, approaching Yunzhou City ants.

At the same time, three coalition catapults clusters that had moved their positions again, and once again launched long-range stone bomb covering and suppression on the city.

Under the command of the flag soldiers on the Yunche not far away, the Hu people's two hundred stone casters shot stone bombs on Yunzhou City like crazy, and they risked the exposure of their positions, which attracted the risk of heavy artillery bombardment by the Qin army. In addition, Yelu Shilu also concentrated the Hu people of up to 30,000 people to form a dense array of bows and arrows, and advanced to within 60 steps under the city. They launched a rushing shot towards the city regardless of casualties, and suppressed the city with arrow rain.

Tens of thousands of Hu cavalry dismounted and gathered into formations, shooting bows and arrows all over the sky towards the Qin army on the top of the city.

Immediately afterwards, hundreds of rushing cars, tower cars, cloud cars, and arrow tower cars seemed to spring up like mushrooms after the rain. Suddenly, they emerged from the rear and moved wildly on the battlefield. On these various tower cars that were taller than Yunzhou City, there were dozens of soldiers on each of them, and on the tall arrow tower cars, there were rows of crossbowmen standing, and Yelu Shilu gathered all the crossbowmen.

This was a thunder attack that Yelu Shilu planned for a long time, and concentrated his efforts to build many chariots, and then suddenly exploded at this time, intending to use these chariot equipment and the spirit of the soldiers to defend themselves to break through the Yunzhou city wall in one fell swoop.

The city of Yunzhou is getting closer and closer.

"The Hulu is going to kill himself!" On the city tower, General Song Xi spat out a thick phlegm and cursed. He turned around and looked at his clan brother Song Jirong and other generals, and said in a deep voice: "Hu Gou is not careful of casualties. If you want to break through in one fell swoop, we have to come out with the real guy."

Song Jirong, the chief general of Yunzhou, was once the military envoy of the Yanei Du, the governor of Ziqing. He was not only Song Wei's nephew, but also a general from the Shence Army who had followed him for many years. In terms of seniority, he can be regarded as the righteous brother of Li Jing, who once became the adopted father of Song Wei. After Song Wei's death, when Li Jing conquered the Liaodong Peninsula and was named the Prince of Andong, he joined Cui Yunqing and others to join Li Jing's command. In recent years, he has been serving military positions in various provinces with a high rank, but he has never had any real power and has no ability.

Entering Li Jing's core circle. This time Zhang Zimian went west, he volunteered. Li Jing agreed to his request for battle, but after the Daibei Dynasty, Zhang Zimian sent Song Jirong, Song Xi, Chang Bao, Yang Lin, Liu Heng, Han Zhong, Liu Jian, Xu Cheng, Cui Decheng, and other military generals under the names of Li Jing's superiors to the city of Yunzhou, and only brought Li Jing's three disciples to the south. Among their people, only Song Wen, who had a good relationship with Li Jing, followed him.

Thinking back to the time when Li Jing was just a united army, which one of them was not a military commander or a general? Just like Cui Decheng, he was just a small custodian under his command, which almost took Li Jing's life. But in time, Li Jing has become the most powerful person in the world, and they are almost on the spot. To put it, Li Jing is actually quite good at them. Now the generals are either a defense envoy or a governor of a province, and they are all commanding the commander. However, if they compare with young people such as Liu Xun, Wang Yanzhang, etc., they will appear to be nothing.
