Doomsday: Humanity shrinks 100 times

Chapter 160 Hot Air Balloon

Lu Yuning was stunned for a moment and said, "The indoor lighting we use now is actually made of pine oil."

"I heard from you that pine oil should produce some smoke when it is ignited. The smoke can be quite dangerous if it is not handled properly indoors. Be careful," Chen Hong reminded.

Lu Yuning breathed a sigh of relief. She hadn't paid any attention to this matter at that time. Fortunately, they had made a ventilation hole. The smoke should have flown out along the ventilation pipe along with the hot air. She should check it again when she gets back.

"It seems that we need to get more rosin. Now a lot of rosin is wasted just for lighting purposes," Lu Yuning pondered.

“Also be careful when experimenting.”

"Why don't Brother Chen come and help us?" Lu Yuning said what was in his heart.

After several exchanges, it was clear that Chen Hong was much more professional in these things. If he could be invited to come over for research and development, it would probably save a lot of time.

"Haha, that's possible, but I actually have a lot of things to do. I'm the main force in the facilities and construction here. I don't have any other skills except strength." Chen Hong smiled heartily and explained the current situation.

"Brother Chen is too modest, but I can also come and help with the construction of Lingang," Lu Yuning said quickly.

Chen Hong thought for a moment, then nodded and said, "If that's the case, then let's do it. I'll go with you. The protection construction over there is more urgent."

Lu Yuning was immediately very happy. With Chen Hong's help, things became much easier. However, she felt a little sorry for Xu Qi and the others. As soon as Chen Hong left, the construction here progressed slowly. However, she would come over to help later.

The two of them discussed it and informed Xu Qi.

Xu Qi naturally had no objection. After all, Lu Yuning had already promised to come and help. In her opinion, they were the ones who made a profit. At present, Lu Yuning's construction ability alone could replace everyone here.
Xu Qi sent the two of them back.

This was actually Chen Hong’s first time to come to the Weiguang Shelter. Although he had heard of it before, he was still surprised when he actually saw their living environment.

No wonder Xu Ting and Xu Qi like to come here when they have nothing to do. No one would want to go back to the gloomy residential area in the forest, he thought silently in his heart.

Lu Yuning took Chen Hong on a tour and introduced him to everyone in Weiguang. Naturally, everyone showed enthusiasm and Chen Hong responded politely.

After they had almost finished their tour, Lu Yuning remembered something and quickly asked:
"By the way, Brother Chen, there is actually one more thing."

"Well, little brother Yu Ning, you say..."

"We're planning to build a steam engine later. See if we can use it to upgrade our weapons."

"I don't know much about the steam system," Chen Hong scratched his head.

"In short, we now have the ability to generate a large amount of kinetic energy. Some tasks that human labor cannot do can be accomplished through steam engines. We originally planned to use this thing as a lifting platform," Lu Yuning explained.

"Well, you could make a slingshot. It should have a longer range than your catapult, at least it could reach the trap."

"Well, I've actually thought about this before. I can use a steam engine to add potential energy to the catapult. But I actually have another idea. I want to build this weapon on a ship."

"On the ship?"

"right"

Lu Yuning roughly told Chen Hong about his idea of ​​the water base.

Chen Hong was stunned, and it took him a while to recover. It wasn't his fault. It was mainly because Chen Hong didn't know Lu Yuning's abilities well enough. Given their own construction capabilities, this idea was really unrealistic. Lu Yuning actually wanted to replicate this new weapon directly onto a giant ship after it was built, so that the base would be like a mobile artillery platform.

Although the catapult is acceptable, the destructive power it produces is still too small, and Lu Yuning is not very satisfied.

Of course, this is also an alternative plan. I just want to see if Chen Hong has any good methods. If a real artillery effect can be achieved, it would be quite impressive to think about it.

Chen Hong pondered for a long time, and finally smiled bitterly: "I'm sorry, with my ability, I haven't come up with any good ideas. I'm not as proficient as you in the field of mechanics. If you have gunpowder now, I can think of a way to make a cannon with long-range strikes. Let me use this steam system to make a weapon, and my role is limited."

Although Lu Yuning was a little disappointed, he quickly nodded to show his understanding.

However, as for gunpowder, they obviously do not have the ability to manufacture it now. The material restrictions are too strict. For something like saltpeter, you can't find a single piece even if you dig three feet deep in the park. They can only think of a way after leaving the park.

"I can't help you with this mobile cannon, but I did think of something else."

Lu Yuning immediately became interested and looked at him expectantly.

Seeing this, Chen Hong chuckled and said, "I understand your idea. You want to replicate all these things on land and use them on ships in the future, so you want to research many things in this direction. Have you ever thought about making an aerial patrol device, such as a hot air balloon?"

Lu Yuning opened his mouth and his expression gradually became excited.

He nodded and said, "It seems that we can give it a try. The materials for this thing are not difficult to obtain."

"It's called a hot air balloon, but it can actually be made by referring to a Kongming lantern. However, it's easy to get off the balloon, but it's not so easy to control its direction. This is just a suggestion. No matter what, safety comes first," Chen Hong suggested.

Lu Yuning nodded slightly.

I have to say that this is a very good idea. If they have the ability to fly in the air, as long as they lock onto targets on land and use the various bombs they have developed, the enemy will basically be doomed.

Before leaving the park, this thing can be said to be their ultimate goal, and they can also put one on the boat in the future. It will be very useful whether for exploration or defending against enemies.

The more Lu Yuning thought about it, the more excited he became. Finally, he slowly exhaled and gradually calmed down. It was not easy to make this thing, so he should first make the more practical protective facilities in front of him.

"Thank you, Brother Chen," Lu Yuning thanked him sincerely.

"You're welcome. But can I make a request?" Chen Hong looked a little embarrassed, as if he had something to hide.

Lu Yuning was stunned for a moment, then quickly said, "Brother Chen, what do you say?"

"You saw my ability last time, my body multiplication. Honestly, that size isn't my limit, but I have to maintain it, mainly."

After he said that, he looked at his trousers. The 1.80 meter tall strong man looked a little at a loss.

Chen Hong’s meaning was quite clear, his pants restricted his multiplication ability.

If you force it to double, it will be more than just an embarrassing problem if your pants are stretched.

Lu Yuning understood instantly and laughed inwardly, but her face remained calm and she didn't dare show it at all.

It seems that this problem has been bothering Chen Hong for a long time.
