"It's a little cold." Zuo Nan didn't joke, the sky gradually lost its light, the warmth suddenly dissipated from the air, and the inexplicable coldness invaded everyone.

The faint light source reflected from the distant planet in the darkness made Yang Chong feel again that when the vitality index was not high or an ordinary person, he felt dark at night, and this faint feeling as if he was blind was very uncomfortable.

Yang Chong said: "Go back, it seems that this planet is not simple than we imagined." ”

When the night fell, the surrounding mountains and forests seemed to come alive, and from time to time there were the roars of various beasts, and Yang Chong and the three of them hid in the simple hut surrounded by tree stumps, and the wind blowing from the source around them was mixed with an inexplicable chill, which made people feel very uncomfortable.

Zuo Nan rubbed his hands, and said with a stunned face: "This is too fantastic, why did it suddenly cool down, but I have completed the visceral jump, and the vitality index has reached one hundred and fifty-seven percent!" ”

Yang Chong shook his head after hearing this, sat on the ground against the stump behind him, and clicked on the microcomputer on his left arm, maybe he could find the answer on it. After the internal organs are completed, the internal organs will provide heat when it is cold, maintaining the temperature of the body and the outside world to the point where people feel comfortable, but Yang Chong waited for more than ten minutes and became colder and colder, as if it was just a simple omen just now, and he was even more curious about the composition of this planet.

"Found it." Shen Yishu's voice trembled a little because of the cold: "There is a layer of ice belt that evolved hundreds of millions of years ago in the crust of this planet, and with the cold volcanoes will continue to erupt outward to wrap the cold air of the planet's ice, when there is no heat provided by the sun of this galaxy, these cold gases will invade the entire earth, bringing extreme cold, and the temperature is normally maintained at minus five degrees, the lowest ......."

"Wait, isn't the volcano spewing fire, how can it erupt cold? And how the planet is covered with ice, what is the structure of this planet. Zuo Nan moved his arms, very uncomfortable with the sudden cold.

"Saying that this is a cold volcano is just convenient for you to understand, as for the reason for the composition, this is even simpler, this is the result of natural selection, and it is the evolution of this planet in natural time......" Shen Yishu said more and more incomprehensible, Zuo Nan hurriedly waved his hand and said: "Stop, I think we should light a fire." ”

As Zuo Nan used an alloy war knife to split the firewood into strips, exposing the flammable tissue inside the wood, Shen Yishu took out the dry leaves he had picked up outside before, and the two alloy war knives rubbed hard, and the sparks that were born ignited the dry leaves, and the sparks slowly burned.

Zuo Nan protected his hands on both sides of the small flame, for fear that the cold wind outside would extinguish the fire that had been so hard to be born.

Yang Chong probably finished browsing the introduction about the climate, and his heart was suddenly in his heart.

The planet's surface is covered with ice, and there are volcano-like structures that spew cold water and cold air into the sea, and the cracks that connect to the ground spread cold air, and the sun does not shine on the earth for more than two-thirds of the more than forty hours a day, the ghostly weather is not so surprising.

It's no wonder that most of the creatures seen during the day are lazy, not full of food and drink at all, but take advantage of the warm day to sleep and rest, and wait for the night to start running and jumping to hunt.

Yang Chong felt that in addition to being cold now, the three of them could survive by relying on a small fire, so he began to click on a large number of video materials in the package, and the practical teaching videos and theories of various warship weapons made Yang Chong a little dizzy just when he saw the catalog. Fortunately, the first chapter of the purpose introduces those that are important, and those are all touchable, and Yang Chong was able to find what he needs and is interested in first.

Waiting for the sound of the fight humming Hai Yi in Zuo Nan's earbuds, Yang Chong found that his heart was relieved, and a few hours passed in a flash, and the firewood in the fire was completely burning, but unfortunately it was still one step behind the cold wind outside, Yang Chong felt that his physical fitness was a little sad, no wonder those people in the tribe were either wearing thick fur or holding a large pile of firewood and rushed home before dark, everything was for a reason.

"Smell it, is there something strange in this fire?" Zuo Nan was looking at Zhengxing, and followed the chivalrous man on the screen to talk and sniffed around, and really smelled a strange smell.

"It's nothing, it's a way for trees to protect themselves, and most of the wood secretes a liquid that repells insects, and when it burns, it produces an uncomfortable gas, which is a strange taste and smell to us." Shen Yishu patted the wood behind him as he spoke: "For example, this kind of tree is not very hard, the weight is ordinary, and the wood is not suitable for construction in the materials, and the wood is not as windproof as the stone wall." ”

"And you're going to let us cut down this kind of tree?" Zuo Nan couldn't help but say.

"I didn't have time to think about it so much." Yang Chong said and looked at Shen Yishu: "So you already had an idea just now." ”

"Yes, when this night is over, we'll start working." Shen Yishu even gave Yang Chong the plan for making entries, and introduced: "There is a four-step plan above, first we need a place to live. ”

"It's not already there." Zuo Nan patted the wood behind him.

"Just because you're willing to call this kind of place your home doesn't mean we're willing to do so, so listen to me." Shen Yishu said unceremoniously: "First of all, it is a place that can shelter from the wind and rain, today is okay, there is no rain on our side, if it rains cold, cold is a trivial matter, I am afraid that the raindrops falling in the air will condense into ice thorns because of the temperature, and even bring unexpected killing." So we need to make a temporary wall out of stone and mud, and then build a three-story roof with layers to keep out the rain, which is our first goal. ”

"The second isn't going to be perfecting these, is it?" Yang Chong saw Shen Yishu's face, thinking that the other party had a plan and order to do things, and he always felt that he was afraid that he would not be able to surpass his own ideas in the future.

"That's right." Shen Yishu's nod made Yang Chong really so: "The second step is to find hard stone, spend about a few days, and build a larger house on the periphery of the house, and the next step is to make the walls of this house to specifications, not the same as those people." ”

Speaking of these, Shen Yishu pointed to a few maps and said: "Look, this is the place where the rock formations exposed outside the ground around us can find suitable rocks, and we can get suitable and enough stones there, we don't need more, just build a big house." The wood of the roof is on this side, and after walking for half an hour from this tribe, there is a forest of stone trees, and the solid wood is not only very hard and wear-resistant, but also heavy, which is an excellent wood for cold and rainy weather, and can be used as a roof to solve temporary problems, but also to lay the foundation for later. ”

"Stop!" Hearing such a detailed plan to build a house, Zuo Nan asked: "This stone forest and stone are not light, right?" ”

"Of course, the walls of the house are heavy to block the attack of the beasts that may come later." Shen Yishu said as a matter of course: "This is just the prototype of the second step, there is a complete house, with a roof of solid wood and stone. ”

"This should already be considered a house with a bit of literacy, what is the third step?" Although Yang Chong thinks that it is good to think so, a comfortable and practical house is indeed in demand.

"Now that you have a durable house, why don't you tidy it up in your free time?" Shen Yishu's fingers slidied, and a projection appeared on his arm: "Look, there is another small room in the house where everyone stores some personal belongings, this side stores wood, and this side is the fireplace where we sit and rest." ”

"Now that we have all of them, of course we will go in a comfortable direction, this beast we can hunt, and the fur on both sides of our body is spread under our body, whether we sit or lie down, it is very comfortable. In addition to these seven or so kinds of fur bedding for us to choose from, we can go here and here every once in a while, and these places have tea leaves like the ones we grow on Mars that refresh the mind after drinking, and where the wood burns to bring a hint of fragrance. ”

"Look here, this beast can be used as a mount. This snake-like fur that lives in cold lakes like a python is used to make sleeping bags, and this kind of tent is used to temporarily camp on the road when we are on long journeys. And ......"

"Wait!" Stunned by Shen Yishu's detailed plan, Zuo Nan began to imagine how to live on this planet, but Yang Chong raised his hand to stop Shen Yishu: "What you said is all enjoyment and exploration, is there any practical value?" ”

"Actual value? What is actual value in your opinion? Shen Yishu said: "This is the third step, improve our lives, we live here for six months, six months is not the time of the earth but the time of this planet, there are fifty days in a month here, adding up to 12,000 hours, and the time of the earth is five hundred days, about a year and a half, is it so long, we are all hiding in this room?" ”

"We're not just hiding in this hut and traveling to other planets." Zuo Nan thought of the task of the space-time center, and then looked at Shen Yishu's plan Although it was beautiful, he thought about the troublesome good life, and sighed: "I support Yang Chong on this point, there is no need to make life more troublesome." ”

"That's not a problem." Seeing that Yang Chong and Zuo Nan didn't think their plans were good, Shen Yishu was a little unhappy: "Why do you all like to fight and kill, or else it's not good to nest here and enjoy this planet?" ”

"If it weren't for the Temporal Hub, I think your plan would be perfect, and I'll do it." Yang Chong spread his hands, but he still agreed with some of them: "But now we better know the urgency before the cosmic war, tomorrow we will build a decent house according to the first step, and then simply decorate it with some animal skins, and then seize the time to read each part of the data to deal with the space-time center and the cosmic war, what do you think?" ”

"There's no fun." Shen Yishu muttered and acquiesced.

"Fun?" Zuo Nan looked at the eyes between the two, a little strange.

"Joy of life!" Yang Chong glared at Zuo Nan and pointed to the microcomputer: "Look at more useful ones, and you won't be afraid of solo missions in the future, understand?" ”

"Yes." Zuo Nan waved his hand impatiently, and he didn't know whether he understood the first sentence or the second sentence.
