Zhang Feng led his men and horses to garrison the territory of Yaohun, neither counterattacking nor sending troops out to ask for help, which really surprised Yu Fuluo.

"Hu Chuquan, what the hell is this damn Zhang Feng doing? I've been flustered lately, and I've had nightmares a lot. ”

Hu Chuquan replied: "King, there is a way that things must be reversed, this is a good sign." ”

"It is a place of death, Zhang Feng and others are trapped here, and if they can survive this winter, they will be considered his ability, and when the spring comes, the ice and snow will melt, and those soldiers under him who can survive will already be exhausted from hunger, yellow and thin, how to lift weapons, we only need to send a fine horseman, and we can completely annihilate these horses."

When Yu Fuluo heard it, it seemed to be really reasonable, and he didn't look into it at the moment, so he handed over the matter to Hu Chuquan to take care of.

A few days later, heavy snow fell in the northwest, and the whole land was covered with snow, and it was cold, and it was winter.

Zhang Feng knelt in the barracks, and the firewood pile erected inside was full of warmth.

"Strategist, have you built the camp tent?"

Li Tao, a military advisor, can be described as a full-time nanny, who not only has to give advice and go into battle to kill the enemy, but also take care of logistics and manage internal affairs.

"Lord, the military tents have been built, but I have been sleeping in the snow for a long time, I am afraid that the tent will not be able to hold up, and sooner or later it will be crushed by the heavy snow."

Zhang Feng nodded, this is indeed a big deal, there are few houses and sparsely populated in the territory, and now it is too late to build wooden houses, but no matter what, the soldiers can't freeze to death.

"Military advisor, it's better to divide the troops and go to Jilusai, where can more than a thousand people live in the wooden house."

Li Tao shook his head and sighed: "This is not the best policy......

Before Li Tao finished speaking, Dian Wei broke in from the outside, patted the snow on his body, and said in distress: "In this northwest place, the wind and snow are too big, and my tent is windy, it's really fucking unlucky." ”

Zhang Feng said with a smile: "The tent is blown away, but you are looking for someone to repair it, what are you doing here?" ”

Dian Wei then smiled honestly: "I came to find the military division, the tent was broken into several pieces, and I had to find a sheepskin to sew it again, and I couldn't get it tonight, so I wanted to go to the military division's tent to sleep for one night." ”

"Oh!"

Zhang Feng responded, but he didn't feel right at the moment, and hurriedly replied: "You go to sleep in the military camp, what about your woman, is it difficult to ......"

"No, no!"

Dian Wei hurriedly explained: "The lord misunderstood, I just came to discuss with the military advisor and asked him to go to Zilong's tent to squeeze around." ”

"You guy, you think it's quite beautiful, and you know that you feel sorry for your woman."

Zhang Feng teased.

At this point, what else could Li Tao say, he could only smile and agree, and exclaimed: "My small tent will be given to you, so that you can be romantic, romantic!" After that, I made do with this Chinese army camp, there is a lot of space here, and it is warm, not bad, not bad. ”

Dian Wei's old face turned red, and he smiled hehehe: "The military advisor will make fun of me, I will go down first and help you get the things." ”

After saying that, Dian Wei patted his ass and ran out in a blink of an eye, which was really funny.

"My lord, the current situation is indeed not very good, if there is no favorable place to shelter from the cold, I am afraid that these soldiers will suffer again."

Zhang Feng frowned, walked back and forth, and suddenly his mind flashed, and he said with great joy: "We might as well build an ice city and build an igloo." ”

Now the snow under Shuofang is similar to the snow in the three eastern provinces that Zhang Feng saw, the weather is cold and the ground is freezing, ice sculptures can be built, and a simple ice city should not be a problem.

"Ice City?"

Li Tao looked at Zhang Feng in surprise, this is too unbelievable, it will be broken when you poke it, and the ice water will melt when you see the light, and you can also build a city?

Zhang Feng said with a smile: "The military advisor is very smart, but he would never have imagined the benefits of splashing water into ice." ”

"If we build mud into clods of earth and sprinkle boiling water on them, we can solidify quickly, and in less than ten days, we will be able to build an ice city."

Li Tao looked at Zhang Feng suspiciously, and immediately followed Zhang Feng out of the camp to gather people and start preparations.

"Zhou Cang, blow the trumpet, and gather all the brethren together."

"Woo ......"

The horn sounded, and the soldiers who were hiding in the tent to protect themselves from the cold came out one after another, looking at Zhang Feng with their hands and feet restrained, what do you want to do in this cold weather?

Zhang Feng shouted and shouted: "Brothers, I know that everyone is cold, and I shouldn't have called everyone out, but in order for everyone to survive this winter, I can only work hard." ”

"Zhou Cang, bring the guy here."

"No!"

After a while, Zhou Cang brought an adobe wooden frame and a hoe that was flat on the ground.

Zhang Feng took matters into his own hands, threw away the ice and snow with a hoe, put the wet mud below into the adobe frame, and after filling it in, he laughed loudly: "Do you want to see a magic show?" ”

"Magic show?"

Dian Wei Mu looked at Zhang Feng, touched the door of his brain and asked, "Lord, what is a magic show?" ”

Come on, make up a new word.

Zhang Feng knew that he had made a mistake again, and hurriedly explained: "It's just a trick, I can make this mud extremely hard in less than a pillar of incense." ”

It is said that the mud can't support the wall, so the ghost believes it.

Dian Wei smiled: "Lord, it's not that I Dian Wei doesn't know, but it's impossible, and I still know the truth that the mud can't support the wall." ”

Slush?

"It's not mud, it's a wall brick, it's enough to build a city, if you don't believe it, you have to look carefully."

Zhang Feng turned around and said to Zhou Cang: "Go get hot water." ”

Zhou Cang got the order, and immediately turned around and went to the camp tent to get a pot of boiling water, and the hot water was misting.

"Everybody's looked at it carefully."

Zhang Feng took the kettle and poured boiling water directly into the adobe frame, and the boiling water quickly invaded the inside along the gap.

When Zhang Feng poured the water, he said with a smile: "The next thing is to witness the miracle, don't blink!" ”

Time passed, and the inner surface of the adobe quickly condensed into ice, and after a while, Zhang Feng ordered Dian Wei to open the wooden frame and found that the original pile of thin mud had really become an adobe brick, and it was extremely smooth.

Dian Wei was stunned, this trick is too magical.

"Lord, teach me quickly, do you need to recite any incantations!"

Zhang Feng slapped Dian Wei's head one by one, and scolded with a smile: "Curse your head, this is science, forget it, I won't tell you, according to what I do, lead people to build adobe, I want to build a city, build a big city." ”

"No!"

Zhang Feng really couldn't explain the reason to them, after the dilute mud is heated, due to the high temperature, a large number of solute particles such as magnesium silica will be generated in it, and these solute particles will act as nucleation points in the crystallization process.

And compared to the water surface, the size of these solute particles will be closer to the critical nucleation size, so that nucleation is easier to carry out, so that it can quickly freeze and form frozen soil.
