To be honest, as a modern person, Tang Jin didn't realize for the first time how terrifying the things he took out were. But when he saw the excitement of Hanerduo and the others, Tang Jin suddenly understood.

The greenhouse is nothing to modern people. If you look for a rural area, you can see a lot of simple plastic greenhouses, and a few experienced farmers can build them by themselves. But here it is different, the greenhouse is enough to change the entire farming environment, they have never heard of it, they have never thought about it.

Crops are planted all year round, and no matter how much wind and snow outside, the greenhouse is still warm like spring, which is ...... Only an immortal can do this, right? Only the legendary formation can do it, right?

"This ...... That's right, and I'm not exaggerating. But can we keep our distance? If you are seen by outsiders, they will think that we are in a multiplayer sport. Tang Jin retreated a few steps back rather embarrassed, his face full of discomfort. Four old men and a middle-aged aunt came to him, he could see the flesh stuck in the other party's teeth, even if Tang Jin was strong in his heart, it was also against the enemy, usually he thought he was a normal person.

For what Tang Jin said "multi-person sports", the people obviously didn't understand what it meant, but they didn't worry too much, now they only have greenhouses in their eyes, and everything else is not important.

"Four elders, you take the drawings as soon as possible to gather the craftsmen and collect materials, be sure to build the greenhouse as quickly as possible, if necessary, no, directly mobilize the army, let those soldiers help as much as possible." Khan Erduo didn't care about his gaffe, so he turned his head and commanded the four elders.

"Wait a minute." At this moment, Tang Jin suddenly interrupted: "Although I have given you the drawings, there are still some places that need my personal guidance, otherwise you will not be able to make up for it yourself." ”

Hearing this, Han Erduo was slightly stunned, and immediately nodded in agreement, she didn't think that what Tang Jin said had any derogatory meaning, in fact, there was nothing wrong with what he said, such a magical thing, although it was not impossible to do it by relying on them alone, but having Tang Jin on the side to guide it could save a lot of time. Of course, the sooner something so important and useful is built, the better.

"Okay, then please Brother Jin bother more." Khan Erduo said immediately.

So, with Khan Erduo's order, the entire Khan Meng tribe started at full power, especially after hearing what they were building, both craftsmen and strong men were like crazy, working hard, thinking about picking up the greenhouse as soon as possible, so as to completely solve the problem that had plagued the entire tribe for nearly a hundred years.

Seeing this scene, Tang Jin couldn't smile bitterly for a while, and finally had to sigh, although the primitive tribe is backward in science and technology, but this person's heart still has character, it is really nothing to say, no one is for himself

Everyone's starting point is for the whole, for the whole tribe. Such a spirit of solidarity is rare in modern society.

The people of the Khan Meng tribe work so hard, as the "chief engineer", it is impossible for Tang Jin to be lazy, but fortunately, he was also a workaholic in his previous life, and this kind of high-intensity work is not a problem for him.

Of course, it can't be said how high the strength is, after all, the greenhouse itself is not very high-tech, and the only thing that is a little technical is the firing of glass and the production of aluminum alloy.

Speaking of which, I have to mention that the minerals in the north are really rich. Tang Jin originally only mentioned bauxite with a small hope, but someone took an ore that met his requirements and sent it over that day.

Tang Jin immediately asked Hanerduo to protect the mine, without explaining the reason, only mentioning that this thing will be useful in the future, and then he pounced on aluminum production, and finally designed a set of equipment for making aluminum under the existing conditions in two days.

With aluminum, then aluminum alloy with great use is naturally something that must be made, fortunately, the blacksmiths of the Khan and Meng tribes are really powerful, Tang Jin just gave an example in bronze, they understood what Tang Jin meant, and on the same day, according to the ratio given by Tang Jin, they successfully made aluminum alloy.

To be honest, at that moment, Tang Jin really suspected that these guys were a group of genetically mutated dwarves, otherwise, why were the forging skills so superb? Even the superb is unreasonable, in the end, Tang Jin can only convince himself with the theory of evolution, when forging becomes a necessary skill for survival, any race can become a forging master.

With glass and aluminum alloy, everything that should be there is basically complete, and the rest is to build. But contrary to the craftsmanship of the craftsmen of the Khan Meng tribe, the craftsmanship of the builders of the Khan Meng tribe can be said to be extremely poor. Breaking glass and installing anti-brackets are the norm, and even more so, the newly built brackets are directly completely deformed by one of them and can only be dismantled and rebuilt.

Because of this, the construction of the greenhouse was greatly affected, and the builders became the target of everyone in the tribe. Tang Jin didn't say anything about this, the construction skills were poor Tang Jin had long expected it, just looking at the houses of the Khan and Meng tribes, you can know that all the yurts are basically not seen in the houses, and the only thing that can be regarded as a building is the wooden fence outside, which is still done with carpentry. They have never built a large house, and it is not a big problem for them to come into contact with this kind of frame structure for the first time.

Fortunately, the psychological quality of the construction workers is strong enough, and they also understand what it means to be shameful and brave, and they have studied hard one by one. But the effect was obvious, and after only a week, they were able to build one out of leftovers

The model then began construction. This time they didn't go awry.

A month later, the Khan Mon tribe planted the area

A huge, transparent house stands halfway through the Crystal Palace, glowing in the sunlight. Opening the door of the greenhouse, Tang Jin smiled and made a gesture of invitation to the people waiting at the door.

Hanerduo and the others were already a little impatient, as soon as Tang Jin opened the door, they rushed in, and as soon as they entered the door, the group screamed in surprise.

"It's ...... It's so warm......" Feeling the temperature that was obviously much warmer than outside, Khan Erduo couldn't help but cry out.

Not only did the second elder and the others who came in with her also look around in surprise, the temperature here was not worse than the northern border in early spring, although this temperature was not enough to grow crops, it was also quite good for people to live in it.

"Don't worry, now that this greenhouse has just been built, you will need to wait a few more days to raise the temperature, and after a while, the temperature inside will be enough for crops to grow." Tang Jin saw that a few people didn't speak, and thought that they felt that the temperature was not enough, so he opened his mouth to explain.

The glass used in this greenhouse is a strengthened version of his special work, even if it is now minus twenty or thirty degrees Celsius, it can still keep the indoor temperature at about twenty-five degrees, but if you want to really reach this temperature, you still need to wait for a few days, without modern heating facilities, you can only rely on the sun a little bit.

When several elders heard this, they looked at Tang Jin in surprise, they were not dissatisfied. In fact, now they are very satisfied with this temperature, and the Khan Meng tribe is not short of food, although they need to save food, but it will not be to the point of starvation. On the contrary, the cold weather often causes some people who do not have extra firewood to keep warm, and with this greenhouse, even if it is not used to grow food, it is quite good to live in.

"Your Royal Highness, we want to ask, this greenhouse ...... Can it be inhabited? The second elder asked hesitantly.

"Resident?" Tang Jin glanced at the other party suspiciously, although he didn't understand why the other party asked, but he still said: "If you can get it, you can, but you can't plant things in it, otherwise people will be easily suffocated; Also, the humidity in the greenhouse is not good for people's health. It's okay to stay for a day or two, it's not good for your health for a long time. ”

"That's right......" The Second Elder's eyes darkened slightly when he heard this, and he couldn't help but sigh.

Seeing this, Tang Jin suddenly thought of something, and said suspiciously: "Second Elder is worried about those clansmen who can't keep warm in winter?" ”

The Second Elder nodded when he heard this, a smile tugged at the corner of Tang Jin's mouth, looked at the Second Elder and said, "Have the Second Elder ever heard of it...... Coal? ”

The second elder raised his head suspiciously, although he didn't know why Tang Jin asked this, he instinctively felt that his question seemed to be ...... Is there a possibility of a solution?
