Landlord of the Tang Dynasty

Chapter 401
"Master Xu's words are true," Feng Li turned to Li Jiancheng and said, "His Royal Highness, these two plans are feasible."

Li Jiancheng nodded, recruited twelve people, each took a token painted with gold lacquer, and sent them all out.The Twelve Golden Orders not only reflected urgency, but also prevented the messenger from being captured by the enemy.After doing this, Li Jiancheng found another tall man. Xu Qing saw that he was about the same size as Zhenzhu Khan.And Xu Qing happened to have a few sets of prairie costumes. Although it was not as luxurious as Zhenzhu Khan, it was understandable that "Zhenzhu Khan" was already a prisoner.

After finishing these two things, Li Jiancheng looked at Xu Qing and said, "These two methods of yours are just that you haven't found a city wall to stop Xue Yantuo's cavalry. If you can't think of that, Gu will kill you."

Xu Qing wiped the sweat from his forehead, grabbed a handful of sand on the ground and said, "The city wall His Royal Highness wants is here!"

"Sand?" Everyone looked at Xu Qing with puzzled expressions.

Xu Qing threw down the sand and said, "That's right, besides sand, what else is there in the vast grassland?"

"But how to build a city wall with this sand?" Everyone asked again: "Master Xu, could it be that you use sand to pile up a small slope? Sigh, this method is good, but the effect of blocking the cavalry is very poor."

Xu Qing smiled and said, "Everyone, this sand pile slope is too huge, and it will definitely not be completed in one day. However, I have a way to gather sand to form a wall."

"Aggregate sand into a wall, how to make it?"

After everyone asked, they lowered their heads to think, and Li Jiancheng also stared at Xu Qing.

Xu Qing lowered his head, held a handful of sand and said, "Look, everyone, this sand is not pure sand, but half sand and half soil. There is soil in it, so it has a certain viscosity, and we can make it into cubes."

After hearing this, Xie Shufang seemed to have thought of what Xu Qing's method was, but there was still a layer of gauze between him, and he felt itchy in his heart, and said anxiously: "Master Xu, although this is half sand and half soil, it is still not sticky enough. One foot, you can't go up any further. A horse can directly cross a one-foot city wall."

Xu Qing said with a smile: "Of course I know that, besides the sand, there is no snow water on this grassland? Well, well, the military situation is urgent, so I won't be a fool. My solution is to use the sand to make cubes , and then build a city wall. Burn a fire, melt part of the snow, and pour it on the sand and soil, because of the severe cold, the water will freeze again, thus freezing the sand."

After Xu Qing finished speaking, all the people present were overjoyed, even a little too excited to speak, intermittently said: "Xu, Mr. Xu, what a genius!" Li Jiancheng also breathed a sigh of relief at this time, and said to the rest of the generals: What are you doing in a daze, not doing something?"

"Here!" All the generals left one after another to find their soldiers.They got together again and discussed how many and wide walls they wanted to build, and then they all started to move.At this moment, Li Jiancheng smiled at Xu Qing and said, "Okay, yes, Governor Gaolan is yours now. However, your life cannot be returned to you, it is still in the hands of the widow."

What else can Xu Qing do, thunder, rain and dew are all the grace of the king, so he can only bow his hands and say: "I thank the prince."

Li Jiancheng laughed and waved Xu Qing to instruct the generals to build the city wall.Xu Qing looked at the scorching scene of sweeping snow and digging sand, walked up to Uncle Xie and said, "General Xie, the sand you dug can be taken outside the city wall, so that a moat can be dug outside the city wall by the way." , and avoid lowering the terrain inside.”

Xie Shufang hurriedly patted his head and said: "General Xu is right, I will give orders to the general." After finishing speaking, Xie Shufang went to the soldiers and horses of his headquarters and said: "You idiots who came without heads, idiots , What are you digging inside! Go! Dig outside the wall."

But where is Xie Shufang scolding his subordinates? He looked around at Feng Li and the others with his hips on his hips and drank, "Haha, you don't know, digging outside the wall can dig out a moat by the way." , without harming the terrain inside!"

After hearing this, Feng Li and the others desperately drove his subordinates to dig outside the wall. With 1 people, it is enough to build a wall with a length of [-] and a width of [-].Xu Qing took three hundred and seventy eighty steps and asked the generals to build according to this length.As for the thickness, in order to ensure the frozen city wall, Xu Qing asked everyone to make it much wider.In this way, it can not only resist the cavalry attack, but also stand on the city wall to counterattack the enemy.

The progress is much slower than expected.Because the temperature during the day is not too low, it looks like a few degrees below zero, and after the water melts, it is relatively slow to refreeze.If you spread an inch of sand, you have to wait a few minutes for watering on the spot.In the evening, the one-foot-high city wall was built, and the thickness was only half of the expected thickness.

Can you think of any way to speed up the progress?

Xu Qing turned around on the "construction site" again, turned to Feng Li's side of the city wall, and Xu Qing discovered the problem.When those soldiers melted the snow, they melted all the snow into water and poured it on the city wall. What a surprise.The ice-water mixture is at zero degrees, and all of it melts. Although it is only a few degrees, it takes a long time to recrystallize.

Xu Qing found Feng Li and said, "General Feng, don't melt all the snow water, as long as it can barely seep into the sand, please tell your subordinates to melt about [-]% of it."

When the melted snow falls on the ground, other snow crystals will be washed away, so it seeps into the sand and can quickly recondense.At this time, Feng Li smiled and brows opened, and suddenly he raised his face and shouted at his subordinates: "How stupid are you guys? Ah! Can't you just melt the snow to [-]% to [-]%?"

He also imitated Xie Shufang, looking around with his hips on his hips and drinking: "It can be melted to sixty percent, it can freeze the city wall and save firewood!"

Seeing this, Xu Qing couldn't help being gratified. Although these people are on this battlefield, they can still maintain such an optimistic attitude and enjoy themselves while suffering.Morale is available!In addition, Xu Qing also realized that the problem of firewood seemed to be a really big problem. If there was no firewood, the snow would not be able to melt.But I saw that each soldier had two bags full of them, the left one was for dry food, the right one was for charcoal, and the charcoal specially brought by the auxiliary soldiers. After the city wall was built, it might last for a day or two.

At this time, Xu Qing also discovered that there was an army that was not moving from the beginning to the end. About 3000 people were sitting in place with a stern expression.

With Xu Qing's method, coupled with the fact that the sky is getting darker and the temperature has dropped a lot, the speed of building the city wall is getting faster and faster.But at this moment, a scout flew in from a distance, hurried to Li Jiancheng and said, "His Royal Highness, Xue, Xue Yantuo is already ten miles away!"

"What? How did it come so fast!"
