Establish diplomatic relations with another world

The class starts at 07:30 in the morning, and the first class is the exam...

Do you feel familiar?

When Shen Yannian was a student, he scolded her for this, but now that he is a teacher, he feels that he just needs to take advantage of the day when his mind is clearest to test out their level!

Half an hour of exam time, very simple content, you can basically get a 56-point paper in an hour!

When they saw the test paper with the red tick mark on it on the podium, the trio plus the little tree man, who had become the most scumbags among the tribe, shivered in the corner.

"Now I can come and get the papers when I call my name." Shen Yannian smiled and sent the papers to the old priest Bai Ye and the others: "You learn so fast, you are all right!"

Full score!

The scumbag group felt a pain in their necks, and their heads shrank back an inch.

"I haven't left the camp for three days, and I just want to read and study when I open my eyes!" Bai Yan's voice began to tremble, trying to recall what he wrote just now.

What are you writing?

Ta Shan was like a dreamer: "Bai Qing roasted full marks, and always eats fried pork ribs in the cafeteria, bringing back full of fragrance!" And his meals are all coarse grains!No meat at all!

Ah Ying was already in despair: "My lord asked me to bring back a box yesterday. I peeked at it, and it was full of exercise books..."

"squeak!"

The three of them looked back, and the little tree man accidentally scratched the stylus on the tablet, tears came from his distressed eyes, and they all showed sympathy.

Poor baby, recently he has been eating Shen Yannian's special nutrient solution, just by looking at his expression of pain every time he eats, you can tell what kind of torture it is.

"I heard that the TV series has been updated, the game has been upgraded, and there are ten new dishes in the cafeteria..."

The three of them looked at each other and drooped their shoulders at the same time!

Ugh!

"Bai Yan!"

"Here!" The one who was shouted swiped and stood up, meeting Shen Yannian's eyes, Bai Yan shuddered, his heart almost jumped into his throat, and he felt that even breathing was so difficult...

"Not bad, I passed!" The cold expression softened a bit, Shen Yannian looked at Bai Yan's unbelievable expression, tried his best to restrain himself, but couldn't help showing a little smile, "There is progress, keep it up! "

"Eh!"

After nearly a week, Bai Yan finally dared to answer loudly in class.

Kazuki and the rest of the scumbag looked at him with envious eyes!

"A Ying, 61, Tashan, [-]!" Shen Yannian went on to report, and the two big men who were still envious and jealous jumped up excitedly, almost falling off their chairs, rushing up to get back the paper at a hunting speed, hehe , really passed!

Now the little tree man became nervous, several roots were rolled together, and he looked in Shen Yannian's direction without blinking, waiting for his sentence.

Bai Yan is still very loyal: "Don't worry, if you don't pass this time, I will go to the kitchen to pick up the firewood for you later. The adults said last time that it is also good for your growth."

Before the little tree man had time to speak, Shen Yannian finally announced his final results.

"Shen Xiaohe, 62! Pass!"

Wow!

The branches on the little tree man's head are brushing and growing, and the eyes are about to shine. Has he passed the exam?He passed?

The quartet of scumbags held the papers and wept with joy.

"Everyone has worked hard during this period of time, and finally the whole class passed this time. To celebrate, today is a day off from class. Let's go to other things!" It can be regarded as a holiday for these people, especially those who were studied. Almost insane.

If you really get tired of studying, it's not good.

Shen Yannian also specially praised: "This time the progress is very great, you have put your heart into it, it is very good!"

Group of four: Your Excellency is so kind, so happy!

"To celebrate, let's go to the kitchen and have a big meal!" Bai Yan suggested with sparkling eyes, and of course he patted the little tree man with loyalty, "Go get you the nutrient solution first!"

These days, I'm so hungry for them!

As soon as they hit it off, the three of them grabbed their schoolbags and rushed out.

Shen Yannian rolled his eyes, why didn't he look so happy while studying?

I have to do things in the afternoon, and there is not much time to play freely. The scumbag group didn't delay at all, and rushed directly to the cafeteria.

There was too much wind and snow outside, and the little tree man shivered as soon as he came out of the heating room. A Ying simply carried him and ran, but fortunately, there was not much way to go.

There was no one in the cafeteria, but fortunately, the ingredients in the freezer were all pre-processed. When Bai Yan went to bring back the little tree man's nutrient solution, Tashan had already prepared a table of hot pot.

However, the little tree man's nutrient solution is quite strange this time. Unlike before, it is mixed with water. This time it is a hanging water bag.

Bai Yan first took two slices of beef and stuffed it into his mouth, then he opened the packaging bag and said to the little tree man, "My lord just got this. It is said to have high nutritional content and is good for your body!" Then According to the operation guide, stick a needle on the little tree man, "how is it?"

The little tree man looked at the water bag curiously, and the nutrient solution water was directly injected into the body through the tube and needle without being absorbed by the roots: "It feels cool and sweet." His eyes narrowed happily, obviously liking it.

"I've been curious for a long time." A Ying asked while eating, "You just eat the nutrient soil nutrient solution, can you also feel the taste?"

The little tree man nodded his head as a matter of course: "That's for sure, they are all nutrient solution and nutrient soil, and the tastes are very different."

The little tree man studied with his elders for a short time, and he divided it according to the various soils he encountered since he could remember. The soil where he lived when he was a child was slightly sweet.

"It's very comfortable to take root in this kind of soil, and it's not easy to be hungry." However, when he went out to wander later, he never encountered such soil again. "Some soil has no taste at all, and the land is full of grains. Sand, no matter how wide the root cover I have, I just don't get hungry and don't absorb much energy at all. Some soil is very sticky and feels disgusting to absorb, and the water is nasty, but it is difficult to filter out. And some soil It is bitter, although I will not be hungry after absorbing it, but I will feel uncomfortable, and I will not be able to grow leaves, I must absorb a lot of water to slowly relieve this feeling!"

The little tree man has never felt that he has had a hard life before, and he feels lucky if he can find soil that can absorb nutrients for him. More often than not, he can't find soil that can absorb water. energy barely alive.

It's not like the fertile nutrient soil now, but the different proportions specially prepared by agricultural experts according to various plants on the earth. The little tree man has tried several kinds, and he especially likes the loose black soil, and he likes the nutrient solution even more. The kind with higher nutritional content.

If we use human food as an analogy, what he ate was weight-loss meals when he was wandering, what he ate was home-cooked dishes when he was a child, and what he ate now is a full banquet...

Tashan likes his metaphor very much: "It's not just a full banquet. Anyway, I see that the noodles in the video are similar to what we eat now. There are so many foods in the freezer. You can choose. How have we seen these before? I'll tell you Said, before we met the adults, we had a meal without a meal. When we came to the Northland, many injured people ran out secretly by themselves, just thinking of dying outside to save us some food..."

Suddenly talking about this sad past, the other two were silent for a moment, and Ta Shan paused for a long time before wiping his face and saying, "Look at my bad mouth, what are you talking about, what we eat now, Even the city lords of the central capital may not have eaten it! Everyone hurry up to eat, Bai Qing also said yesterday that the passage outside the boundary needs to be expanded and strengthened, and there is a shortage of manpower, so we will go over to help after eating."

Aying Baiyan naturally did not refuse.

But the little tree man was a little anxious: "Are you guys going to do something? What about me?" Before, the little tree man was used to being alone, and the little tree man never thought of being alone, but now he is used to everyone sitting together to talk and study. Leave him alone, and the little tree man quits.

Bai Yan scratched his head: "That can't be helped, aren't you afraid of the cold? Besides, we are going to work, and you can't do much!"

The little tree man was not convinced: "How do you know I can't do it?"

He just followed Bai Yan and came to the construction site. He said it was a construction site, but he was actually planning to build a big shed, including all the boundaries to the camp.

The small passage made before was obviously not safe when the beasts attacked. For Shen Yannian's safety, after the snow wall was built, Bai Ye asked someone to arrange to build a shed.

Build a shelf with steel, and then cover it with concrete cloth, which can basically achieve a defensive effect after being poured with water.The concrete cloth is fire-resistant, and when the time comes, an oil drum will be installed on the top. If it is in danger and burns, it will be enough to resist for a while.

Now what everyone is doing in full swing is putting on airs.

It's so easy!

The little tree man stood there watching for a while, waving the rhizome and rolling up the steel to serve as a porter for others.

Bai Qing was standing on the shelf and was about to put it up. Just now, when he touched it with his hand, the steel pipe was gone, and he shouted: "This side needs a steel pipe." The next second, a thick root rolled over the steel pipe.

Diagonally across from him, Jiang Liang also started to shout: "There's no more steel here..." Before he finished speaking, the root of the little tree man wrapped around the steel pipe was in front of him.

The little tree man waved his thick rhizome, and stabilized the audience by himself!

"Yes!" Bai Yan's eyes lit up.

Ah Ying was amazed.

The little tree man raised his chest proudly!

Bai Qing turned to Uncle Shui next to him: "Isn't the construction team always short of manpower? I think he is quite suitable. Let him be included in the construction team and let him be responsible for the delivery!"

Uncle Shui thought of the little tree man who was working harder and harder, and wanted to beat his insane grades, so he bowed his head silently.

It seems that he likes playing games?Now, adults can finally stop worrying.

In addition to learning to sleep in the future, he seems to have no time to do anything else...

In the research institute, the samples in the tunnel brought back by Bai Ye and the others were tested one by one. The ones that could be seen inside already contained more than [-] different kinds of creatures, and the types of ores reached as many as [-] kinds. Most are iron and coal.

This is surprising.

Everyone knows that coal is an extremely thick layer of black humus accumulated on the ground from the branches, leaves and rhizomes of plants for millions of years. Under high temperature and high pressure, after a series of complex physical and chemical changes and other factors, black combustible sedimentary rocks are formed.

But the problem is, this is the Northland, a world of ice and snow, and it doesn't mean that this planet has always had scarce soil. How did such a large coal mine support a large area of ​​trees to survive millions of years ago?

Could it be that these ore mountains were once covered with a lot of soil?

This is really confusing!

But there are also good things. The new materials made of the ore transported before have been used in aerospace engineering. The new satellites have been quietly sent into the sky, and the data sent back show that they are more suitable for space than the previous satellites.

And this material can be used to make space suits, which can effectively isolate substances that are not conducive to humans in a vacuum.

This represents a step closer to human exploration of space.

"It's really a jewel planet!"

At this time, several ferrets were running in the tunnel. They had been running like this for several days, but they did not find any clues of the target.

Suddenly, their eyes lit up, it was clearly Hey Yo's cave, but it was as bright as daylight.Several ferrets looked at each other in a humane way, and were about to turn around and leave. Suddenly, there was the sound of someone talking in front of them, and a ferret suddenly raised its head, sniffed the air, and screamed excitedly.

This person, this person has the smell of the object they are looking for!
