Doomsday: Humanity shrinks 100 times

Chapter 232 Night Action
"Nitric acid, I have the impression that this kind of laboratory supplies are difficult to buy. It also requires some certification and official registration. I guess it's hard to find in residential areas."

Zhang Song nodded and said, "Yes, we did have some in the lab before, but we've used it all up. These dangerous reagents are strictly controlled and can't be bought in ordinary stores. However, the good news is that I know of a manufacturer that specializes in selling chemical reagents. The bad news is that their factory is five kilometers away from us."

Lu Yuning breathed a sigh of relief. Although five kilometers was indeed a long distance for them, it was acceptable compared to other completely unsolvable problems.

But five kilometers is indeed a very long distance for them, and it is not just a simple trip there, but they also need to transport a large amount of nitric acid back, which is the biggest problem for them.

Lu Yuning pondered for a while, and finally decided to go back and discuss it with everyone.

In addition to the nitric acid problem, another tricky issue is that the production process of gunpowder is still very difficult. It’s not that the process is complicated. After all, the most difficult part of producing nitric acid has been replaced by other methods.

The main difficulty lies in the fact that the experimental reagents are very harmful to humans. Whether it is strong acid or strong alkali, it is difficult for humans to withstand it. Regarding this point, it may be necessary to eventually develop a set of experimental equipment suitable for use by shrunken humans. This can only be solved by Lu Yuning.

After the two things were confirmed, Lu Yuning said hello to Zhang Song and returned to the physics laboratory, where everyone from Weiguang was waiting.

Lu Yuning told everyone about the reagent factory and the issues of nitric acid collection.

Zhang Xinyue seemed to be thinking about something and then said, "I do have an idea."

Everyone's eyes were focused.

She paused and continued, "Since this factory has plenty of chemical raw materials, why don't we just get everything done there and come back later?"

Everyone looked at each other, and apparently realized that this idea seemed to be a good one.

However, Lu Yuning finally shook his head and said, "Assuming that we have enough other raw materials, we should ship the nitric acid back. This will be a good solution. Otherwise, we might need more people to go, and the transportation cost won't actually decrease. In the end, we still need to ship all the gunpowder back."

Gu Yu had already thought of what he was going to say, and asked, "Do you need me to fly over?"

"Well, this is the best method I can think of right now. You take Old Wu and me over there, and then we can process the nitric acid and put it into the space. The only problem is the upper limit of the space. I don't know if one trip will be enough. If it doesn't work, we may have to go again, and Gu Yu may have to work hard."

Gu Yu quickly shook his head and said, "It doesn't matter. For me, flying one kilometer or five kilometers makes no difference. What I'm using is not my physical strength but my supernatural power."

Zhang Muyan suddenly said, "Wait a minute, would it be better if I could go with you?"

"Well, I've considered that. But then, when we walk back, we'll have to drag the goods on the ground. I'm mainly worried about running into animals, which would be dangerous. Also, the goods on the ground are too conspicuous. If they're spotted by other survivors with bad intentions, it would be troublesome."

Zhang Muyan thought for a long time, and finally nodded and said, "Okay, that's right. The more streamlined the staff, the better."

"Well, let's make it a deal. Old Wu, Gu Yu, and I will go to the reagent factory. The others will stay in the laboratory for the time being. It may not be so peaceful here. The Bloody Hands might come again, so you should be careful."

Everyone nodded to show their understanding.

The action was confirmed, and Lu Yuning also had to make some preparations. The other two were not very strong in combat, so they had to rely on him.

Lu Yuning had two new sets of armor ready for them both to wear in case of danger. However, Gu Yu was a bit special, and the full body armor was too much of a problem for him. They needed to consider making him a separate set of armor. Also, without Zou Yunxin, their bombs were useless, and Wu Xiao's combat effectiveness plummeted.

However, Wu Xiao's spatial ability can still play an unexpected role as long as it is used well.

The first thing he thought of was to ask Wu Shumei and others to get some powerful chemical reagents. Although there was no strong acid now, the power of a strong alkaline liquid like sodium hydroxide should not be underestimated.

However, this sodium hydroxide is only effective against shrunken humans, but it is not as powerful against large animals. However, it is enough. Compared with animals, Lu Yuning is actually more worried about the threat from humans.

In addition to these chemical reagents, to be on the safe side, Lu Yuning also made a few sharp projectiles for Wu Xiao. These projectiles were covered with spikes and could be used as hidden weapons.

Combined with Gu Yu's movement speed, as long as he can throw it accurately on the enemy's face, the enemy will be skinned alive even if he doesn't die.

As for Gu Yu, he really couldn't think of any good weapons. The best way was to cooperate with Wu Xiao, so that the effect of one plus one would be far greater than two.

Lu Yuning spent half a day preparing food for several days, and the sky gradually darkened.

However, the three of them planned to set off.

That's right, operate at night.

This may seem dangerous, but it is the safest option.

Unlike before, the biggest problem with moving at night is that it will attract the attention of nocturnal animals, and the terrain is rugged and difficult to move.

Now that they are flying, the biggest threat actually comes from birds in the sky.

However, there are very few birds that are active at night, and now it is winter, so many creatures hibernate, such as bats.

Overall, walking on the road at night is actually safer, and Lu Yuning's strong perception ability is also a guarantee.

The only problem is the flying vision and direction. If you fly too fast and accidentally crash into a tall building, or get lost, it will be troublesome.

But they were lucky, the moon was very bright that night.

It is not used for lighting, but can be used as a direction sign.

As for the problem of car collision, it is also easy to solve. Just fly higher than the nearby buildings.

Lu Yuning and Wu Xiao were a bit nervous on this trip. After all, this was their first time traveling such a long distance. Furthermore, it was so high up! Although it was pitch dark and they couldn't see anything, they could still clearly feel the wind blowing past their feet.

After imagining some more scenes, Lu Yuning's palms suddenly started sweating while flying in the air, and Wu Xiao didn't dare to breathe.

As for Gu Yu, he was extremely excited. In his words, I have wanted to fly like this for a long time!
