Doomsday: Humanity shrinks 100 times

Chapter 241 Mysterious Organization
Zhang Song expressed his feelings, so Lu Yuning didn't say much. Although she wanted to invite him in, she couldn't say too much, otherwise it would make the other party less favorable towards her.

Since they have a good relationship now, it doesn’t matter whether the other party joins Weiguang or not. At least they can use this place as an outpost in the future.

The two chatted for a while, and the amount of sodium nitrate crystals they produced was far from enough, so they prepared to use up all the materials.

Zhang Song's subsequent operation still amazed Lu Yuning. Transporting liquid raw materials from the raw material cup to the reaction cup was actually a relatively complicated process.

However, with Zhang Song's flexible use of his special abilities, the liquid in the raw material cup would eventually draw an arc in the air and then fall steadily into the reaction cup in the middle, without a drop splashing out.

The nitric acid and sodium hydroxide placed in the reaction cup will eventually complete the final reaction according to the ratio.

The large bottle of nitric acid that Lu Yuning brought back was eventually used up, and the container containing sodium nitrate crystals was full.

The most critical part of the production of black powder has been completely completed, and the next step is to mix it with charcoal and sulfur in proportion.

Zhang Song and his colleagues were unable to produce charcoal in large quantities before. They had made some by carbonizing wood with concentrated sulfuric acid, but the amount was too small.

Fortunately, some coal was found in a factory one kilometer away, and a lot of it had been transported back earlier.

They also have professional transportation talents. Lu Yuning did not ask in detail. He only knew that it was probably a kinetic energy-type ability, which was nothing more than an ability given by the initial momentum, which could be translation or rotation.

So there is no need to worry about the storage capacity of charcoal, the last thing is sulfur.

The main role of sulfur in gunpowder is to promote combustion. Although it is not easy to burn itself, it has the effect of promoting oxidation and is also a key material.

The storage capacity of sulfur is not large, and it is mainly used for experiments in the laboratory.

However, the proportion of sulfur in black powder is not high, only 10%, so you don’t need too much. You can check whether there is any in the reagent factory later and then ship some back.

After the three materials were prepared, Lu Yuning called for help, mainly asking Wu Xiao to be responsible for transporting the materials and adjusting the proportions of the materials.

Sodium nitrate accounts for the largest proportion, and the other two are actually auxiliary materials.

According to the ratio, Wu Xiao quickly piled the three materials together.

All that was left was for Lu Yuning to break them down again and mix them back together.

He hadn't tried this method of recombining mixed materials before, but he thought it shouldn't be a big problem. He remembered that he could use his supernatural powers to deal with rust before, and rust was actually a mixture.

Under Lu Yuning's special ability, all three materials were crushed and finally mixed evenly.

Because of the charcoal in it, the overall color of the product is black, and it looks quite realistic.

Zhang Song walked forward, picked up some gunpowder, squeezed it in his hand, and then nodded and said, "It should be fine."

He seemed a little excited. After all, he made it with his own hands, and for a chemistry enthusiast like him, it was worth being happy about.

"Let me get some out to try." Wu Xiao also came over excitedly, ready to collect some and put them outside to try to light them.

Seeing this, Lu Yuning quickly pulled him back and said, "Wait a minute, I want to do an experiment."

Wu Xiao was stunned, somewhat confused.

Zhang Song also asked with some doubt: "Experimenting here?" Lu Yuning nodded and explained: "It's not a fire experiment, it's a method of using supernatural powers that I thought of before."

Wu Xiao finally reacted and understood what he meant.

Previously in the reagent factory, the three of them had wanted to experiment with Lu Yuning's other ability, the possibility of replicating objects. However, since Lu Yuning's ability was time-limited, they couldn't conduct the experiment that day.

He had always kept it in mind, and the reason he didn't come back to try it was mainly because he was afraid of wasting it.

After all, the cooldown time of his ability is too long. If he can really copy items, it would be better to copy some scarce items, such as the gunpowder he just made.

If successful, making one portion will be equivalent to making two portions, which can save a lot of materials.

Zhang Song obviously still didn't know what he was going to do, but he still stood aside, waiting to see what Lu Yuning wanted to do with some curiosity.

Lu Yuning hesitated for a moment. Zhang Muyan had said before that this time ability was a rather shocking ability. There had been people with this ability before, but they were eventually killed. He had also been reminded to use it with caution.

He had actually used it before when the two groups met, but it was just to freeze people, so it was hard to associate it with the time ability.

However, this ability to trace back is not easy to get away with, and I will definitely have to explain it to Zhang Song later.

He thought for a while and decided to confront Zhang Song directly. After all, Zhang Song was still thinking about taking care of his students in this end times. There was nothing wrong with his character. He was also smart and would not say anything nonsense.

Moreover, the two of them will have to work closely together in the future, and this ability will be exposed sooner or later, so it’s better to just make it clear.

Thinking of this, Lu Yuning said: "Teacher Zhang, in fact, crushing and reassembling is just one of my abilities."

Zhang Song was stunned for a moment, not quite understanding what he meant. Then he seemed to come to his senses, slowly widened his eyes, and looked at him in disbelief.

Lu Yuning continued, "Just as you thought, I actually have two special abilities. The other one is the ability to rewind time within a certain range."

Zhang Song was already a little surprised when he heard Lu Yuning say that he had two abilities, but when he heard that the second ability was related to time, he was stunned for a moment.

"Are you serious?"

Lu Yuning nodded in affirmation.

Zhang Song took a long time to come back to his senses. He then looked at him seriously and said, "You must not let anyone know about this ability. Otherwise, even if the world is big, someone will find you. As far as I know, there is a mysterious group out there who specializes in suppressing people with this kind of ability."

This time it was Lu Yuning who was stunned. Apparently, this was the first time he heard the news, and it seemed to be different from Zhang Muyan's version.

"A mysterious person? From the settlement?"

Zhang Song shook his head and said, "No, they are much more terrifying than Blood Hand and the others. I have also heard about them. However, since there are rumors, it is likely to be true. It is better to be cautious."

"Is it stronger than the organizational capabilities of large settlements?"

It seems that another strange force has appeared, and it is targeting his super-dimensional ability.

According to Zhang Song, they are incredibly capable and can track down a human being in this vast world.
