After another three days, the little tree people finally opened their minds, and it was obvious that the tree people instinctively paid attention to the growth of the plants around them, and then took care of them with the knowledge that they had accumulated for many years. They do this completely out of instinct, just like Qi Jiashi, who is an elegant handsome guy when he is in human form, but when he sees a bone to gnaw on the dinner table, he will immediately uncontrollably let the dog genes in his body do the trick, and immediately the image will be completely destroyed, and his mouth and face will be full of grease stains. What Gwen couldn't stand the most was that sometimes he would dig out half-gnawed bones from the bed or cupboard. How did you get here, of course, you have to ask Chigashi. As for how he got to Gwen, it's hard to say...... As long as everyone understands.

This made Xu Zheng breathe a sigh of relief, although the little tigers were obviously keen to follow Aosen's foolishness, the enthusiasm of the little tree people had diminished a lot, showing their interest in the surrounding flowers and plants. Fortunately, otherwise, I don't know how to explain to Old George in the future, and I actually taught a group of violent tree people to come out, which is too different from the original temperament of the tree people. However, there are still sequelae left by Aosen, and the little trees sometimes don't know which nerve is suddenly in the wrong line, and they will wave their arms and legs for a while while while walking, and there are obvious traces of Aosen's sword skills......

In short, the little tree people are still prodigal sons, and they have not been completely harmed by Orson, and are now qualified for the position of gardeners. Xu Zheng gave them the rice and glutinous rice seeds brought by Ling Meimei and let them play on their own. Anyway, now that the manor land is large and scarce, they can plant wherever they like, and they will talk about it when they make a comprehensive plan in the future. Don't worry about the ability of the tree people, in the entire Aris Continent, there is no gardener stronger than them, and in the matter of planting, even the natural magic of the elves has to stand aside.

Let's be honest. The little tree people are cute, but they shake in front of you with green leaves all day long. Especially the seventy-three guys dangling together, it's always dazzling to look at it for a long time. Now that these little tree people have found something to do on their own, their eyes are suddenly much clearer, and everyone except Ao Sen breathes a sigh of relief. The bearded Orson has some gains and losses. trained the little tigers more and more, and let them stretch out their pink and tender little paws to make trouble all day long.

Two days ago, the first team of four leopards and seven tigers led by Baghdad, the leopard tribe, had arrived, and eleven more people had been added to the manor to consume food, and the food was even more scarce, and the urgent need for feasible means of transportation to carry out trade and trade had been put on the first agenda, and it had become the most urgent problem to be solved.

Xu Zheng had to turn around and urge the members of the Starlight Song and Dance Troupe to step up their training. He even began to build the first Terran flying machine by himself.

The rest of the mature plans Xu Zheng already has, and the design drawings of the entire aircraft have been completed in his spare time, and the main difficulties at present are the lack of materials and the problem of the engine plan.

I can't make any materials, so I have to wait for the little gnomes to make it up. The problem with the engine is also due to the limitations of the current level of technological development of the gnomes. I couldn't find a suitable plan so I kept putting it away. Based on the craftsmanship of the gnomes, they can only make steam engines, not stronger ones. It's simple. If you give you the most primitive tools and materials, you can't build a nuclear-powered one with the most advanced technology, plasma propulsion or relying on interstellar particle streams, like stellar sails, that's a joke.

The steam piston engine is ridiculously backward, and the gnomes can rely on it to fly out of the planet's gravity. It's pretty remarkable. Before the human flight technology could fully use the piston steam engine, it had been completely eliminated, and the gnomes insisted on using it for so long, and there was only one possibility, that is, it had not yet developed a better one.

In the afternoon, Ling Meimei and the other three dwarfs once again transported parts and food, and after the handling was completed, they stayed in Xu Zheng's temporary flight garage to watch Xu Zheng splicing materials.

Xu Zheng's entire aircraft has not yet been fully formed, but the tail and two wings are almost spliced, and some rudiments can be seen.

At this time, it has been seen that the whole aircraft adopts a single-wing structure, because in order to greatly improve the climb force at low speed, a flat-stretch structure is adopted, unlike most aircraft whose wings have some backswept angles. On the wingtips, in order to resist air turbulence and fly smoothly, duck-like fins were also added, which attracted the attention of the gnomes, and they asked Xu Zheng about the role of this structure.

After Ling Meimei understood, she continued to look at Xu Zheng's one-winged wings, and asked worriedly: "Can a layer of wings fly?"

Xu Zheng was looking at the drawings, thinking about the structure of the engine, and replied without raising his head: "There is no problem." Just a little bit more on your speed. Now what needs to be improved is the structure of the engine, the power of the steam piston type is too low, not only can not meet the requirements, but also too much waste, and it is true that it needs to be replaced urgently. Especially for long-distance flight, it is necessary to have a more reliable engine. ”

Ling Meimei nodded: "I think so too, the entire power room takes up a lot of space and weight, and in order to fly, most of the energy is consumed on it." ”

"That...... Xu Zheng ......" Sang Keke looked at Xu Zheng and stopped talking.

Xu Zheng looked up at him and asked, "What's the matter?"

Sankike hesitated, and finally said, "Uh...... It's okay. ”

Xu Zheng looked at him strangely for a long time, and continued to hang his head to study the drawings.

Silunlun and Sankike looked at each other, and Silenlun whispered, "Why don't you ask him to take a look?"

Sang Keke shook his head: "It's not that you don't know my crazy brother, maybe it's a joke in Xu Zheng's eyes." ”

Si Lunlun said: "It doesn't matter if you look at it. Xu Zheng is also not the kind of person who likes to laugh at others. ”

Ling Meimei nodded: "It's true, the humans in this manor are very different from the people outside." If it were another human, I would have been caught exchanging things for the clan in the first place, let alone flying here every day. Show him, I don't know why, but he knows obviously more than we do. ”

Xu Zheng put down the sheepskin drawings in frustration and sighed: "Okay, you've been muttering for a long time, what do you want me to see?"

Sankike said embarrassedly, "My brother, uh...... His name is Sandodo, and he is a notoriously madman in the clan who likes to be whimsical and design things that are completely unrealistic. You know, he can't even pass the junior technician exam. Almost 10 out of 10 of the things he designed had no practical value, either the materials were super exaggerated, or there was no feasible technical support at all. For example, the last time he whimsically wanted to use the power of the three suns to drive the mechanical work......"

It's not impossible to use solar energy, and the dwarf named Sandodo wants to get this, but he really has the ability to think in a pioneering way. Xu Zheng suddenly became a little curious about this dwarf.

Sankike continued: "This time he heard that Ling Meimei was designing a new type of transport aircraft that needed more powerful engine support, so he designed a new engine, which was claimed to be much better than the original, and it was an epoch-making new engine. The three of us didn't understand it for a long time, and we thought that it was all a fantasy, just like his other designs. ”

Xu Zheng looked at Ling Meimei: "You added them to your group?"

Ling Meimei nodded: "I wanted to do it alone." Later, I thought that it was better for everyone to be together than to be alone, and the three of us were good friends, and the two of them also wanted to take this opportunity to challenge the position of senior technician, so they were together. Anyway, dwarfs are used to cooperating, and my original idea of doing it independently was just to impress my father. You can also achieve this goal by doing it together, not to mention having good friends to do it together, which will make people happier. ”

Xu Zheng liked them even more, and said with a smile: "Take it to me to see, what kind of epoch-making thing it is." ”

"Do you really want to see it?" Sankike hesitated, he was very protective of this brother, although too many of his ideas were unrealistic, but this did not affect his respect for his brother, and he didn't want him to suffer another blow in front of Xu Zheng.

"It doesn't matter if you see. Xu Zheng smiled and raised his finger above his head: "I swear in the name of the Star Alliance Scouts that I will never laugh at your brother's masterpiece." Believe me, sometimes unrealistic fantasies are the beginning of all great inventions. ”

"Oh well. Sankike took out a roll of sheepskin from his arms, handed it to Xu Zheng slowly, and said: "My brother is actually very smart, he was better than me in everything when he was a child, and I made the first dwarf spinner with his help." Who knew what was going on later, he always liked to think about something that he didn't have, and the people in the clan always liked to laugh at him...... It's excessive. No matter what other people laugh at, I always think my brother is a terrible dwarf. Here you go, no matter what, please don't laugh at him!"

Xu Zheng nodded, unfolded the parchment roll, and stared at it with only one glance.

Seeing that Xu Zheng's face changed slightly, the three little ones all asked, "What's wrong?" Sang Keke was even more worried, and said, "If it doesn't work, forget it." I'll keep it as a keepsake. ”

There were three parchment rolls, and Xu Zheng continued to look at the second one, sighing: "Your brother is really amazing, he can actually come up with such a thing in the current engine structure." ”

Listening to Xu Zheng's words, which obviously meant a tone of praise, Sankike asked in surprise and joy: "What is painted? I can't understand anything except that it is still steam as the driving force." ”

Xu Zheng stretched out his fingers and flicked the parchment scroll, and said, "This is indeed an epoch-making thing for your current level of science and technology. It's crudely designed, but it's a steam turbine engine!"
