Rebirth and stocking up in the apocalypse, I have tens of thousands of supplies for the world

"Well, leave these trees to me. I'm a bit bored."

Hua Ningyao smiled and nodded, with a gentle light in her eyes. She was very fond of the plants in the community, especially the old tree, which witnessed the passage of time and the continuation of life.

After saying that, she turned around and walked lightly back into the house, leaving the guy there. She ignored the man because he had been forced by her to be an NPC. Although he had changed, his personality remained the same.

Nowadays, he no longer complains all day long like he used to, but he has not gotten rid of his habit of meddling in other people's affairs.

"Hey, hey, you guys are ignoring me?"

Chen Hui felt a little dissatisfied, and his voice was filled with a hint of resentment. However, no one responded to him, as if he had been forgotten by the whole world.

A surge of anger surged in his heart and he wanted to curse, but when he remembered the warning from the game world, he had to hold it back.

[From now on, if you curse people for no reason again, I will pull you in once you curse ten times. You will only have ten chances to survive. In other words, you can curse as much as you want, but if you curse a hundred times, you will be dead.]

This warning frightened him, and since then he has indeed changed a lot and no longer curses people as recklessly as before.

But his nature did not completely change, he just transformed his way of cursing into staring at others every day.

Just like now, when she is watering the trees he will also make noises. He used to curse at her, but now he grumbles.

Sometimes he would curse people accidentally, but he would cover his mouth and stop talking halfway through.

. . . . . .

When Hua Ningyao went out, an official car was sent to pick her up, and it was Uncle Xie who sent someone to pick her up.

"Uncle Xie, what's wrong?"

"Xiaoyao, you are here. I have a problem here. I want to ask if you have any ideas for solving it?"

He pointed at the mecha and said to Hua Ningyao. Hua Ningyao walked around the mecha twice, then turned around and asked.

"What's wrong with it?"

“Not being able to take off is the biggest problem.”

"Oh? No wonder when I saw the mecha advertisements before, they all walked on the ground."

Hua Ningyao immediately understood what the previous advertisement was about. No wonder it looked a little weird.

"Is the takeoff logic of the plane unusable?"

She had learned the manufacturing method from this guy, but there was a problem: the current design, materials, and energy were all different.

"No way, not enough motivation."

Uncle Xie frowned and shook his head. He had also thought about using the rocket's take-off logic, but the mecha was not used as an aircraft.

If it is just a simple imitation, it won't work. It must conform to the actual situation. Hua Ningyao looked at the mecha in front of her. She had learned mecha manufacturing, but the materials and many structures were different, and she couldn't solve it all at once.

. . . . . .

Uncle Xie also wanted the mecha to be able to fight in the air. For some reason, he felt that the mecha should look like this.

If it was just a flying vehicle, he could just design a spaceship, why would he go through all the trouble of making a mecha?

"Well, let me think about it."

Hua Ningyao touched his chin, took the design drawings and schematics of the mecha from Uncle Xie, and personally entered the mecha to try driving it.

"Xiaoyao, you are amazing. You can actually drive a mecha without any adaptation. You should know that our pilots have trained for half a year before they can drive it."

Uncle Xie was surprised. Not everyone can operate a mecha. It requires a very strong physique.

Hua Ningyao sat in the cockpit, operating various buttons and joysticks skillfully, feeling every movement and reaction of the mecha.

She found that although the mecha already had basic flying functions, there were still many areas that needed improvement and optimization.

"Well, I know what the problem is."

Hua Ningyao muttered to herself. She felt that the driving experience of this mecha was similar to that of the most basic mecha, but with a few more cumbersome things.

These extra parts not only increase the weight of the mecha, but also affect its flexibility and maneuverability.

"Change this and that, and then there's the fuel issue."

Hua Ningyao pointed to the structural diagram of the mecha and said that she believed that the existing fuel system could not meet the needs of the mecha to fly in the air for a long time, and that it was necessary to find a more efficient and powerful fuel to replace it.

"Fuel? Energy cartridges won't work?"

Uncle Xie asked. He has always believed that the energy box is the most suitable fuel for mechas because it is small in size, has high energy density, and can provide continuous and stable power output.

“It’s not that it can’t, it’s that the energy box doesn’t have enough power to support it to fly in the air for a long time and conduct high-intensity combat.

We need a more powerful fuel, like a fusion engine or an antimatter reactor."

Hua Ningyao explained that she knew very well that only by solving the fuel problem could the dream of mechas flying freely in the air be truly realized.

One reason is that it is too heavy and cumbersome, and another reason is that it lacks energy. The instantaneous energy required to fly is huge.

But now even if the energy box is burned out, it can't provide the mecha with flight power. Uncle Xie looked at it for a while and his eyes lit up.

. . . . . .

"Yeah, why didn't I think of that? Thank you, Xiaoyao, you are really a genius."

"My uncle's praise makes me feel embarrassed."

"I'm telling the truth, you're amazing, why don't you come work for us?"

"No, I'm busy."

"That's right. Your talisman is very useful. I calculated before that according to the previous situation, the energy shield will have a window period every ten days. Now the calculation result shows that there will be many more days."

Uncle Xie said with a happy look on his face, and Hua Ningyao nodded.

"It would be nice to have help."

"Hey, can you use your talisman on this? Make it lighter?"

"..."

"let me see."

Hua Ningyao was silent for a while, then spoke slowly.

"I really didn't expect that the talisman could be used in this way."

After saying that, she looked at Uncle Xie, who said with a serious expression.

"Think quickly. We don't know how the current situation will develop, but I believe that mechas will play a key role in the future doomsday survival."

"Ok!"

Uncle Xie was very excited. If someone had told him that talisman paper could solve scientific research problems in the past, he would have slapped him. However, now he has become a loyal fan of Huaningyao Runes.

Not only that, he also applied runes to the energy box to maximize the utilization of energy. He didn't expect the effect to be so amazing.

His explanation for this phenomenon is that this symbol is also a kind of science, which can change the arrangement structure of molecules, protons and even smaller things.
