The three girls were woken up by Guyu.

Hearing Gu Yu's tone of anxiety and tension, the three girls ran out without even having time to rub their eyes.

"What's wrong with Guyu?"

"What happened?"

Guyu pointed to the fog that had not yet dissipated and said:

“It’s getting warmer again!”

Only then did the three girls realize that the previous stuffiness around them had returned to their previous sultry heat.

"Why is this happening? Why does the temperature change at a time?"

Xiaoqing looked confused.

Xiao Man'er thought of something, looked at Guyu, pointed to the sky, and said:

"Can they be them?"

Gu Yu nodded and said:

"It is very likely, at least it cannot be ruled out."

Xiaoqing and Tangtang didn't understand what Gu Yu and Xiao Man'er were saying, and they thought Xiao Man'er pointed at the sky and said to God.

Xiao Man'er came to Guyu and asked:

"Are they trying to save us?"

Gu Yu pondered:

"It should be, but there is another possibility."

Xiao Man'er:

“What is possible?”

Gu Yu climbed down the bamboo ladder and replied:

"Remind us for a while and a constant cold."

"ah?"

Gu Yu stood below and waved, saying:

"Don't "Ah", we have to be busy. Even if my guess is only 30% possible, we must solve these 30% of the worries."

The three girls didn't understand why Guyu did this, nor did they know what he guessed, but they saw Guyu's seriousness and seriousness.

They are already used to following Guyu's arrangements here.

The four people were under the tree and began to look for all the firewood that could burn according to the requirements of Guyu. They sent bundles to the tree house, placed close to the tree house, and kept it outward until it was hung on the five-fingered tree branches.

This can accumulate enough firewood to keep warm, and use this firewood to increase the thickness of the walls of the tree house and increase the warmth coefficient.

In addition to dry firewood, they also made more hay and spread the entire tree house more than half a meter thick, but Grain Rain was not satisfied and believed that the more they would be better.

During their busy time, the weather changes from warm to cold, and then the cold changes several times.

Guyu specifically counted the time and concluded that the alternating time of cold and warm is uniform.

"It seems that I'm right. The temperature and temperature are almost equal in several times. They thought of a way to save us by entropy and ten thousand tranquility."

Here he and Xiao Man'er are the only ones who are taking care of the hay, Xiaoqing and Tangtang pick up the dry branches.

Xiao Man'er asked while baleting the hay cut by Guyu:

"What entropy stops ten thousand quiet?"

Gu Yu continued to wave his saber without raising his head, saying:

"The second law of thermodynamics, they found the entropy of the operation of the incense burner landscape space, and now they are ready to stop this entropy and restore the most original order of this space, so that there is a chance to squeeze us out.

But in this process, they use the reverse operation of the principle of cosmic entropy increase, that is, the entropy reduction, so the temperature here will be very low and the duration will not be short."

Xiao Man'er sincerely exclaimed:

"Uncle, you know a lot."

Gu Yu threw the cut hay to Xiao Man'er and replied by the way:

"In the future, I will introduce the Nerve Knife to you. I know Entropy, which was what he taught me on an island. I used to think that he had a brain disease, but now I don't think so anymore. After going out, I must talk to him for a good chat."

As he said that, he climbed into the tree house with two large bundles of hay. Seeing the thick hay, enough for four people to come out of a grass hole in the house, he nodded with satisfaction.

He threw down the hay quickly and told Xiao Man'er:

"You guys continue to pick up firewood. I'll go to the bamboo forest to find out if there are any bamboo insects or other foods that can be eaten. You must also prepare some food to have the energy to resist the severe cold."

Xiao Man'er said anxiously:

"Then, will I come back from the river to get water?"

Gu Yu waved his hand and said:

"No need to fetch water. Our water is enough for the time being. When the temperature drops later, it will continue to snow. We will not lack drinking water."

He said that, he turned around and left in a hurry.

After walking two steps, he remembered something and turned around and told:

"Looking at the watch time, when the weather changes from cold to warm, the warm weather exceeds the previous time, stop working immediately and wait for me in the tree house. You must remember this clearly."

Xiao Man'er nodded vigorously and said:

"Don't worry! I'll be optimistic."

This little girl is not stupid, since Gu Yu guessed that this was a signal given by the outside world.

Then, once this rhythm changes, it proves that the continuous cold is coming.

With its infrasound power, Grain Rain is walking on flat ground in the mountains and forests under the moonlight.

He was extremely fast, and closed his eyes and distinguished everything around him about a hundred meters.

Soon, more than a dozen bird eggs were added to his backpack, but in the next half hour, he had no gains except some wild vegetables.

And this time the weather was warmer, which has reached twice the previous one.

"The rhythm has changed, it's about to begin!"

Guyu looked at the dozen or so bird eggs in his backpack, but he couldn't give him any sense of security.

Four people, this is not enough for a meal.

Seeing a hint of chill in the air, Gu Yu was even more anxious.

Just as he was anxiously stamping his feet, something underground caught his attention.

"Ha, there's this thing, I shouldn't starve to death now!"

He hurriedly ran a few steps, then squatted down on the spot, started digging with a saber, and dug out a few strokes, looking like a sweet potato. He was so big that he was afraid that he would not have three or four kilograms of rhizomes.

He kept digging, and he dug out several such rhizomes one after another, of varying sizes, and together, it was probably more than ten pounds.

It was too late to clean it. Seeing that the water vapor in the air around me had begun to condense, Guyu knew that he didn't have much time and had to hurry back to the tree house to hide from the cold.

"Do your best and leave your will. I hope these foods will keep us going for the next time!"

Thinking of this, Guyu did not hesitate, carried the backpacks containing the rhizomes and strode towards the tree house.

The temperature dropped faster than the Guyu project, just like the Mid-Autumn Festival in the season is coming, and the heat he exhaled instantly fell on his face, and his beard turned silvery white.

The grass under your feet became fragile. When you use your feet, it was not the previous sway, but was kicked into several sections, and it fell to the ground with a crisp sound.

Guyu's windbreaker was carried by a gust of cold wind and all the heat was gone. The cold was like a sharp steel needle, tingling his nerves.

"Oh no, in a few minutes, my toes were already frozen and numb. My strength was disappearing, and the cold plundered the heat in my body. There were less than fifty meters left. I want to speed up, and I must be quick!"

He was already trembling, and the coldness penetrated into his bones, making him tremble uncontrollably.

"Click!Click!Click!"

When Guyu was looking for food in the mountains and fields, his body was wet with the dew that was made from the cold and hot. At this moment, these clothes knew how hard they were as hard as iron.

This made Guyu spend every step he took to fight against these ice frozen on his clothes.

Several times such ice cracks and bent, his pants, clothes, and joints swayed, actually cracked their mouths fragilely.

The cold wind poured into the clothes through the gap, making Guyu scream in pain.

"Ten meters! I'll arrive in just ten meters!"

He thought, but his body did not obey the command and stopped in its original place, like a statue.

Seeing Tangtang and the three girls looking at him by the bonfire, they all stood up and were about to come down to save Guyu.

Gu Yu knew very well that at this time the three girls left the bonfire and lived for thirty seconds under such temperatures. Their clothes were too small, and thirty seconds were not enough for them to carry themselves up.

So he used his last strength to shake his head at the three girls beside the bonfire.
