Outside Qingzhou City, a huge dock fort appeared on the ground, the flag on the dock fort was fluttering, the blood dragon sword and shield flag was fluttering in the wind, and four war horses could drive side by side on the city wall.

Wu Jue and the others will stand on the city wall, with a smile on their faces, and beside Wu Jue, there is Liu Ming, a doctor from the School of Engineering and a waiter of the Ministry of Engineering, and everyone looks at the fortress in front of them from time to time, and they all show satisfaction.

"Before becoming a courtier of His Majesty, I once heard that there is an engineering college in Taiyuan Academy, specializing in the design of various siege weapons, more powerful than Bianjing's Guangbei siege city, I used to think that it was an exaggeration, but now it seems that the engineering college is more powerful than the legend, this bull crossbow was originally to be pulled by a cow, although the power is gone, but the rate of fire is much slower, now after the engineering college so a way, three people can fiddle with a bull crossbow, the rate of fire is much faster, the range is not short, amazing!" Wu Jue looked at the huge bullbow on the side, and his face suddenly showed a look of satisfaction.

"It's all Your Majesty's foresight, and now the College of Engineering and Zhao Song's Guangbei siege work are united, among which there are tens of thousands of craftsmen, not only in terms of production, but also in terms of research, which are far beyond before." Liu Ming said triumphantly.

With the relocation of the imperial court, the College of Engineering also moved to Bianjing, and merged the former Guangbei siege city to form the current College of Engineering, which has improved a lot in terms of scale and strength. At that time, he was just a small apprentice in the Guangbei siege work, but now he is the real power person who controls the engineering college, and has become a squire of the Ministry of Engineering.

"What I value more than these siege machines is this thing called cement. It is easy to carry, and the resulting wall is very strong. Liang Zhong patted the city wall and said. All the generals also nodded again and again.

The fact that the dock fort can be built so quickly and put into use so quickly is due to a building material called cement, which can be quickly formed and durable, and it is difficult for ordinary broken city cones, flying stones and other things to cause damage to it, and those bows and arrows are even more difficult to shoot into the city wall, unless it is a crossbow and other objects at close range, it will shoot into the city wall and cause damage to the soldiers behind the city wall. After everyone saw it, they were even more amazed.

"Hehe, this cement thing is also a suggestion given by His Majesty, the Institute of Engineering studied for a long time before it was made of the structure, composed of limestone and clay, and the College of Engineering experimented many times before it came out, and this time I got some to come to Qingzhou, also for experiments." Liu Ming said with a smile: "In the future, we will use these things when we build the city wall and lay the official road, but the cost is higher in a short period of time. ”

Liu Ming looked at the corpses under the city and the arrows occasionally visible on the city wall, and looked a little proud, this is the masterpiece of the engineering college. If in the past, Guangbei siege could only do something, bows and arrows, siege equipment, the highest is firearms, these things are the work of inferior talents, now it is different, every thing that comes out of the engineering college is a fine product, respected by the generals in the army. Even with his own status, he has risen a lot.

"With this cement, Wanyan Zonghan and Xia Quan are probably looking at the city and sighing." Wu Lan said with a smile. followed Wu Jue to become Li Jing's courtier, and Wu Ling also had to admit that it was still very promising to follow Li Jing, at least, sitting at home, and the war exploits came out of thin air.

"I believe that at this time, the news that His Majesty captured Han Shizhong alive and repelled Yue Fei has reached the ears of Wan Yan Zonghan, I don't know what kind of mood Wan Yan Zonghan will have." Wu Jue was a little proud in his heart, he was a subordinate, and was forcibly pressed by Li Jing in the position of the commander of the army, although Liang Zhong and others obeyed orders, but they may not be able to look down on themselves in their hearts, and now they can finally prove themselves with their own ability.

"Even if you know, what can you do? Can you still defeat us? Yang Zaixing said indifferently.

Wanyan Zonghan in the city has no way, the dock fort built with cement is far stronger than the ordinary camp, at the beginning, he was afraid that Li Jing was in the camp, Li Tang's army was innumerable, so that Wanyan Zonghan did not dare to attack Li Tang's camp, and when he knew that Li Jing had left the camp, the opponent's camp had been replaced by a dock fort, and after an attack, there were countless casualties, and the dock fort has not changed at all, and now the dock fort has been formed, Wanyan Zonghan and Xia Quan have forcibly attacked, and there is no effect.

"Li Jing is too treacherous, he has been playing us for so long, in fact, he has already led a large army to attack Han Shizhong and Yue Fei, this Zhao Gou is really incompetent, nearly 200,000 horses have not captured Jianghuai, if this is us, only 100,000 horses will do." Wanyan Zongbi looked depressed, and said to Wanyan Zonghan: "Li Jing defeated Han Shizhong, we have not made much progress in Ludi, you can tell the emperor about this, if we don't send troops and horses to support, once Li Jing returns to the division, we will not be able to resist." ”

Wanyan Zongbi didn't have this mind before, but in the past few days, he attacked Wubao to no avail, which made him see the strength of the Tang army, so Wanyan Zongbi had to suggest that Wanyan Zonghan ask Jinting for reinforcements.

"Wanyan Yan's mother is ready to lead 50,000 troops south to support Qingzhou." Wanyan Zonghan shook his head and said: "On the one hand, the imperial court is preparing to deal with the traitors in Hebei, and on the other hand, it is also unifying the grassland, at least let us have the same status as Li Jing on the grassland, only by occupying the grassland, can we get more cavalry, and compete with Li Jing for the world, and the future battle with Li Jing is no longer here, but in Hebei." Hebei is suitable for cavalry, Li Jing has occupied most of the grassland, and there are cavalry in the northwest, competing with Li Jing, and he doesn't care about one city or one place. What makes me very curious is that the materials that Li Jing used to build the Dock Fort, in just two or three days, the Dock Fort has taken shape and can withstand our large-scale attack, don't you feel strange? "In this regard, Wanyan Zonghan is more mature than Wanyan Zongbi, and he sees not only local wars, but also farther.

"You mean the Dock Fort? What can be strange, the Han people's favorite thing is this kind of strange and obscene skills, there is nothing strange. Wanyan Zongbi said indifferently.

"It's not that simple." Wanyan Zonghan shook his head and said, "Now a dock fort is so difficult to attack, what if it is a city in the future?" If the Central Plains is full of such cities, how will we attack, and conversely, if we all use such things to build cities, how will Li Jing attack? ”

"This?" Wanyan Zongbi's complexion changed, if it was really like Wanyan Zonghan said, how could Dajin defeat Li Jing and seize the Central Plains? For a while, Wanyan Zongbi didn't know what to do.
