As Song Yong expected, when the sky here on the grassland gradually darkened, the sky changed rapidly along with the sky, and the weather fell in a straight line.

When the sun goes down, the temperature is still around -zero.

So tonight, when the crescent moon rose alone among the treetops, the temperature around them was already close to minus ten degrees.

Even after adding a thermal underwear and a cardigan to his thick winter suit.

Song Yong, who was already quite bloated, still felt that the cold wind blowing on his body brought a slight chill to his body under his clothes.

also made every time he spoke, he brought out a long haze.

And even in such a terrible temperature environment, on the entire hillock, at the edge of the surrounding mountains and forests, it is still a scene of hot labor.

"Attention! The tree is going to fall~"

Such a long voice came from the edge of the mountain forest from time to time.

In that position, there were hundreds of strong men among the primitive people, and the big trees that were suitable for use were about to be cut down, and the roar came out of their mouths.

In the process of wielding axes and saws, they soon became sweating profusely.

So much so that they took off the warm animal skin that had just been draped on their bodies for a short time.

At the same time, every time a big tree was cut down to the ground, several people hurriedly stepped forward and cut off the unused tips and redundant branches.

So that the other companions could carry it and send it to the top of the hill to pile it up as materials for later construction.

At the top of the hill, on the edge of the hill, hundreds of men with shovels and manuscripts were working hard to dig the foundations of the wall necessary for the outpost.

The sooner you build a working wall, you will have more protection for your life.

There is no need to emphasize this point more than Song Yong, the commander-in-chief, everyone knows such a point.

So, except for the fifty sentinels who were released from afar, everyone else, including Song Yong, bowed their heads and worked hard.

The only thing that is special is that Song Yong arranged a relatively easy job for his sister Gardenia:

It is to make specific statistics, how much food is concentrated, and how long it must be able to maintain the state of the army eating mountains and empty mountains like this.

And when the time comes, bring someone to prepare enough hot water for everyone, as well as food for the stomach.

And the reason for this is just that Song Yong doesn't want his sister to have a pair of rough and calloused hands under such heavy physical labor.

In that case, how inconvenient it is......

This continued until about eleven o'clock in the evening.

'Ding~' sounded, it was Song Yong who dug out a spark in the soil on the ground after going down with a pickaxe.

It's not like he's digging up some metal in the ground.

But as the temperature gradually decreases, at this time, the temperature of more than ten degrees below zero, the soil on the ground is as hard as an iron plate.

If you don't put in some effort to dig, the result of a pickaxe will only leave a white spot on the ground.

Even if you have enough strength, you can dig out a piece of dirt that is not too big, but if it takes a little longer, it will be too taxing on your hands and physical strength.

At least I have been busy until this time, and my physical fitness is under the good drama of many fire sacrifices.

Song Yong, who asked himself that he was no worse than those special * soldiers, still felt a tingling pain in the tiger's mouth, and his arms were sore.

By now, he didn't have any strength in his arms.

It was also at this time that Ling, who had been wielding a sapper shovel beside him, suddenly screamed out of his mouth after a shovel went down.

Song Yong turned his head to look over, and then could see what was happening through the distant firelight.

It turned out that Ling had enough strength and beckoned a shovel to the ground.

From the modern plane, the multi-functional sapper shovel with a high-quality steel mouth is nothing, but in the primitive era plane, the newly equipped wooden handle is unbearable, and it is broken in two.

depressedly, he threw out the half-cut wooden handle in his hand at once.

Ling turned her head to Song Yong, and said in her mouth:

"Brother Yong, it won't work like this anymore, the soil is getting harder and harder, and I'm afraid it will be more difficult to dig after a while, and everyone won't last long like this." ”

Because I already knew in my heart the necessity and urgency of building the wall.

Ling didn't say anything, such as tomorrow, when the weather is better during the day, let everyone work.

The problem is that he is now counting on Song Yong to come up with some good solutions, and in the face of the expectations of his generals, Song Yong is also in a dilemma for a while.

There are so many good ways to do it, and they come as soon as they are said.

According to the legend of the modern plane, there is such a classic legend.

It is said that during the Three Kingdoms period nearly 2,000 years ago, the famous historical figure Cao Apu and the fierce general Ma Mengqi had a great battle in Guanzhong.

Cao's army occupied the south bank of the Wei River and faced repeated attacks by the cavalry of the Ma army.

Because the camp was surrounded by soft sandy soil, it was impossible to build a city at all, and it was impossible to defeat Ma Mengqi.

At this critical juncture, one of his generals, Lou Bo, suggested that the city could be built with earth and sand, and then filled with water in the middle.

Because when the water freezes, it becomes hard like iron, so that the city can be built overnight.

So, Cao Agui followed the advice of his subordinates, and after successfully completing the construction of the city, he turned the danger into safety......

I have to say, this kind of story sounds pretty cool, and when it comes to doing so, I realize what a fucked thing it is.

At this moment, Song Yong faced Ling's inquiry and wanted to copy this method.

Only then did I know that there was such a good thing, at least it was not suitable for me.

Take sand and water to build a city, that is also a premise, you can first dig out the sand and soil on the ground?

Isn't he worried now because the ground is too hard to dig for?

In addition, according to his own observation in the evening, there was no beach on the edge of the lake, and the natives could not be allowed to go to the lake to fish for sand in such a cold temperature.

That's going to kill people.

Secondly, during this period of time, there is still a temperature above zero during the day, and the city wall that freezes at night will collapse after thawing during the day.

Regarding such a point, Song Yong also has very big worries and concerns.

In the end, under Song Yong's repeated consideration, he still came up with a solution that was not a solution:

Anyway, in the mountains and forests where logging is being done, there are redundant tree trunks and branches all over the ground, and people are dragged back to use them as firewood, and after the ground is heated and softened, they can hurry up and start their work.

In this way, while burning the fire and digging the soil, it can also warm everyone's body.

As for the continuous fire that was lit in such a night, it was possible that the wild people who were scattered outside could discover the consequences of their movements in advance, and now Song Yong was a little bit of a careless.

After getting Song Yong's instructions, Ling took people to work on this matter.

And Song Yong also stopped the fight with the frozen soil, raised his electric horn, and shouted at everyone:

"Rest for a while, I'll have hot soup and dried meat ready, and we'll work hard when we're done, and I'll treat you to a big meal on the day the outpost is built. ”

The name of the Gray Rabbit tribe's cuisine has also been spread in the southwest region for a long time.

Among the people present, most of them ate a meal of beef noodles from the Gray Rabbit tribe on the night they helped harvest the wheat.

It's such a noodle meal, and it is estimated that it is also the best memory of their lives.

Therefore, when Song Yong's promise sounded, the entire vicinity of the hill cheered loudly.
