In the Chengqing Hall, Li Shimin was playing chess with Changsun Wuji. Li Kuan came to spoil the fun, and even asked them to watch the city wall and fireworks. What's so good about the city wall, and it's just after the New Year, and it's still broad daylight, what are you watching?

Fireworks?

Besides, they are old, so I don’t see what the importance is. Just take Jinyang, Xincheng, Li Xiang, Li Jue and the others there. Children like to be lively, so I would be happy to let them go during the day!

"As for me, it would be nice to play chess with you, Lao Taishan, and look back on my time."

"Yes, Your Majesty, your Majesty will be accompanied by an old minister, so you can go and play with peace of mind!"

Play? Who is Changsun Wuji knocking?

I knew he was Lao Taishan from the East Palace, but I didn’t know he thought he was a political enemy! Isn’t it fun to give him some eye drops?

Ignoring Changsun Wuji, Li Kuan turned to Li Shimin and said: "Father, let's take a look. I even called the generals from the North and South Yamen to come together."

"If you want to chat, there are many people in the Craftsmanship Department of the Engineering Department, so it seems more suitable!"

Well?

Li Shimin frowned when he heard that Li Kuan called all the generals from the north and south. Is this going to be a cigarette or a fight?

After grabbing a handful of cement from the prince's mouth and looking at the new wall that Li Shimin smashed with a sledgehammer, Cheng Zhijie could hardly imagine what kind of magical material it was that could turn from ashes to stone.

"Nonsense! I just said to use a siege chisel. He is too lazy to do it!"

What's even more uninteresting is that the prince also asked people from the Ministry of Works to unload bags of sand and build a wall as low as one person, and ordered everyone to stick their heads out of the wall!

Mo Yiyi only saw the new wall glowing with fire, and then smoke rose up, and pieces of gravel shot out; until the smoke cleared, everyone looked at the wall with a blank expression, or rather

The ones are more wrong, they are pieces of broken stones.

Li Shimin knew that it was a small murder weapon, and my general was a fool. It was not because of the old gangster that he was slow to react. Speaking of friendship with the royal family, who did he have? Li Kuanshunde and others came from Jinyang.

Here!

Mo Yiyi also brought Fang Xuanling, Li Kuan Youji, and Li Jiba to leave. Mo Yi in front also came to introduce the specific situation to Yu Chang and Jiang Xingben, the ministers from the right and left of the Ministry of Industry.

Generals Gongsun Wuda, Liu Shili, and Suo Ting also had helpless expressions on their faces when they saluted, because Yu Chang gave eight hammers and asked the generals to take turns to check, but can the eight old gangsters give us that chance?<

/p>

The two city walls were built completely in accordance with the standards of Chang'an City. The right side used old materials, while the left side used new materials. The result is obvious. When it comes to the use of tools, people have their own methods.

Broken.

"My father is wise, and what my father said is absolutely true. It is not true to use the son's spear to attack the son's shield."

"Qianfan, what are you planning?"

Li Kuan sold a lawsuit and had to ask the emperor to move and see the things before he was willing to explain the reason. Li Shimin smiled helplessly. Among so many children, Li Kuan was the only one who dared to talk to him like this.

Cheng Zhijie and a group of ministers were invited to a far away place. They were all very cautious about setting off fireworks, so of course they had no problem with it. But seeing the serious look on the prince's face, everyone was trying to hurt the prince's face.<

/p>

Li Shimin grabbed his eldest grandson's arm: "Prince, our relationship is between father and son. He needs to take less care of you Zuo Wuwei!"

To say it is too different, Changsun is afraid that we will understand if we hear it. Here is a complicated point: from the perspective of sturdiness, the new material city wall is at least eight times stronger than the old material;

Before getting upset, Cheng Zhijie raised another question: Are economical and affordable materials bad? But if that kind of material is used to build a city, how can one capture such a city?

"But you forgot, I asked you to move here to watch the fireworks. Fireworks are not the solution."

In front of the new city wall, eight siege chisels bounced off in succession. Mo Yiyi's interest became low, and he ordered the trebuchet to be pushed away. The nearly 1,000 kilogram stone finally hit the surface layer, and it was thrown out in one go.

The old wall of Xiaokeng is getting better.

Sitting under the chair, seeing that there was only a few feet of opening behind him, Mo Yiyi asked curiously: "Qianfan, aren't those fireworks like that?"

In terms of cost, it eliminates the need for rock cutting and a small amount of transportation and labor costs. The cost of the same city is only 10% of the previous cost. In terms of the time and convenience of repairing the city, the time is shorter and the efficiency is lower.

Alas! Mo Yi, Yu Chang, and Jiang Xingben all shook their heads. Those old stubborns really wanted to die in the Yellow River. How could we understand "science"!

Mo Yi is also a general who has fought hundreds of battles. I should be clear that there are many ways to capture the city, such as taking the city, water attack, etc. If such a city falls into the enemy's hands, how much life will it take to pay for it?
p>

When I arrived at the Craftsmanship Department, I saw eight old gangsters, Yu Chigong, Li Shimin, and Liu Hongji, "researching" behind two 20-foot-long city walls. They also held a stick in their hands and banged it very seriously.<

/p>

Well, Cheng Zhijie has always followed what is good. Since it is a specific arrangement, we old guys are disgusted by this. I would like to see what kind of tricks the fireworks can do during the day.

Okay! Anyway, you have nothing to do, so just take a look and treat it like coaxing the children. Li Shimin also ordered Wang De to call the children down. It’s not good to be alone.

But Mo Yiyi sided with Li Shimin and the other seven: "I also want to know how long his new material can withstand!"

Changsun smiled and responded: "Yes, the entire wall is not made of bricks, iron bars or new materials."

Coming up from the stage and walking to the side, Cheng Zhijie revealed the trick: "Qianfan, there are no iron bars or masonry outside!"

The ratio of losses to the enemy during an siege is usually eight to one, or seven to one. To capture a city made of that kind of material, the actual losses would have to be doubled. No matter how bad things are, you must use restraint methods.

Otherwise, it is not flashy but solid waste.

"Alas! You were very naive that time. To be honest, I, Lao Cheng, am a real person and I can't rely on him."

Attacking a city couldn't be more unfamiliar to Cheng Zhijie. Since there are no new materials for building the city, I don't have the patience to wait. Okay, that's it. With a wave of Mo Yiyi's hand, the officials of the Ministry of Works can do whatever they want.

Broken leg.

But the eldest grandson stopped Wang De, and then said to Cheng Zhijie: "Father, the fireworks today are suitable for children to watch."

The danger is safety, you will know by looking at the effect! Changsun waved his hand, and immediately no soldiers lit the fuse, and the fuse burned the package on the wall. There was only a special sound like thunder, and there was no obvious earthquake. It was as bad as a god.

It’s like showing off your power.

We must strengthen the walls of the existing city. We cannot choose to fight on the surface, make slabs, and pour water. We must build roads, which is even more convenient. If we dig the foundation two feet deep, we cannot build a road that will last for decades.

The road.

Seeing his eldest grandson looking embarrassed and being surrounded by generals, Cheng Zhijie, who was in a bad mood, also joked with Li Kuan, Fang Xuanling and Li Ji: "It's really boring when the prince is not prepared either!"

......

But Xiao Tang's ability to obtain that kind of material just shows that Li is the chosen one by destiny, which makes me quite unhappy. Mo Yiyi was also extremely short-sighted and seized the opportunity to slap the emperor's horse badly.
Chapter completed!
