Natural disaster at the beginning: I will lead the system to build a safe zone

Developing gunpowder is not an easy task. Although Shi Anan has the detailed theoretical principles given by the system in his mind, he lacks relevant practical experience after all. Gunpowder is a high-risk product, which can cause casualties to R&D personnel if not handled with care. Therefore, they are very cautious during the production process.

As for the proportion of gunpowder, although everyone knows the formula of "one nitrate, two sulfur, three charcoal", the specific amount has to be mixed little by little. But when they tested it, it was almost impossible to ignite or the power was so small that it was almost gone.

Shi Anan led Li Changlin and others to study hard for more than half a month, and the best result they got was just firecrackers. Seeing the crackling firecrackers on the ground, everyone was a little puzzled. Is this the powerful gunpowder she mentioned?

This is certainly not gunpowder!

However, this time, Li Changlin and the others were a little skeptical: "Teacher, is this formula really correct? Does it really have the earth-shaking power you said?"

Shi Anan refused to admit defeat: "Of course it's true! How can research and development go so smoothly? There are still more than a dozen options. We will know after we try them one by one!"

Li Changlin and others had no choice but to continue following her experiment. However, it was normal to have accidents during an experiment.

It was a quiet morning when suddenly a loud "boom" was heard from the gunpowder research and development room. The roof was blown off and people in the distance kept looking over there from a distance.

For safety reasons, the gunpowder research and development laboratory was located in an open space far away from residential areas. This was not only to facilitate testing, but also to avoid unexpected situations like today.

Xiao Yi rushed to the scene as soon as he learned about the explosion in the gunpowder research and development laboratory. At this time, the black smoke in the house had not completely dissipated. The roof was blown away and a part of the wall collapsed. This demonstrated the power of the gunpowder.

However, Xiao Yi's attention was obviously not on the gunpowder. He rushed in and found Shi Anan and others. Fortunately, they had taken good safety measures and reacted quickly. They found a place to hide at the moment of the explosion, so no casualties were caused.

But not being injured doesn't mean not being embarrassed. Shi Anan stared at his messy hair and face covered in black ash, muttering to himself as if possessed by a demon: "No, how could this happen? The power is obviously enough, why did it suddenly explode?"

Not only her, Li Changlin and others were also muttering to themselves about the data in the experimental records. Seeing this scene, Xiao Yi held his forehead and walked forward to interrupt them.

"An An!"

Shi Anan was startled by Xiao Yi's shouting. She raised her face and looked at him with her big, bright eyes: "Little pretty, why are you here? Did the explosion scare you?"

Xiao Yi sighed and said helplessly: "What do you think? Such a big commotion must have scared mother and the others a lot. Are you injured?"

Shi Anan laughed a little embarrassedly and said, "It's okay, I'm fine. This was just an accident. There won't be such a big noise next time."

Xiao Yi obviously didn't believe her. Since he started developing gunpowder, he had been working day and night and forgetting to eat. "Go back and have a rest first. We need to clean up here too."

Shi Anan was about to refuse. Her research and development was almost complete. How could she take a break at this time?

But when she saw Xiao Yi's serious face, she felt a little scared for some reason. Shi Anan still nodded in agreement. She had no idea now, but maybe she could think of the reason for the failure after going back and resting.

She told Li Changlin and others to go back and rest first, and asked someone to clean up the messy scene. The house that was blown up had to be repaired. Fortunately, there was more than one house in the yard. Xiao Yi helped them move the experimental materials to another intact house, and then took Shi Anan home first.

After walking out of the R&D room, Shi Anan felt a little tired. She walked while leaning on Xiao Yi as if she had no bones. Except for a moment of stiffness in the beginning, Xiao Yi relaxed and let her lean on him and walk slowly.

At this time, Shi Anan suddenly thought: "Xiao Piaoliang, didn't you take people out to tap rubber? Have they all been harvested now?"

Xiao Yi was helpless: "I've been back for three days."

Shi Anan scratched her head and said, "Oh!" She was indeed a little confused now. "Now that the rubber has been harvested, we have to start making rubber."

Xiao Yi reached out and helped Shi Anan, who was about to trip because she didn't look at the road, and then said, "You don't have to worry about this. I have already asked someone to learn how to make the recipe you gave me."

Shi Anan nodded. She really didn't have the extra energy to pay attention to rubber. Compared to rubber, gunpowder was more important.

Xiao Yi sent Shi Anan home in silence all the way. Shi Anan then fell into a deep sleep. She indeed had not had a good rest during this period of time.

……

I don’t know if resting is really useful. Anyway, when An An woke up, she felt that her confused brain was much clearer, and she also had some ideas about the stability of gunpowder.

Another half a month has passed, and today is the day to officially experiment with gunpowder.

After solving the problem of gunpowder stability some time ago, they conducted several small-scale experiments in the laboratory, and there were no more accidents of blowing off the roof. Today's experiment is a field test.

The amount of gunpowder this time is different from that in the laboratory. It could really kill someone if it's not handled properly.

Therefore, the location they chose for the experiment was a flat open space far away from the people. The reason they did not choose a mountain was that they were afraid that the mountain would collapse due to an accidental explosion. After all, the place where they lived was not too far from the mountain, and a collapse of the mountain could easily cause a landslide.

In addition to the R&D personnel, those who came to view the experimental results today included Xiao Yi, and Mu Shan, Jiang the Butcher, Yan Fei and others from the security team.

When gunpowder is produced in the future, the people who will have the most contact with it are the security team, so letting them know the power of gunpowder will also help them understand this weapon.

In order to ensure the safety of the experiment, Li Changlin and others first buried the explosive package in the soil, and then connected a very long fuse. Except for the person who lit the fuse, Shi Anan asked them to keep a distance of at least 100 meters.

Yan Fei couldn't stop talking. Seeing Shi Anan asking them to stay so far away, he couldn't help but ask, "Miss Shi, how can we see the results of the experiment if we stand so far away? The explosive pack can't explode that far!"

Shi Anan glanced at Yan Fei with a meaningful look, and did not explain: "You will know in a while, I hope you won't cover your ears later."

Upon hearing this, Yan Fei patted his chest and said, "Don't worry, I definitely won't cover my ears. I didn't even cover my ears when the fireworks were so loud before. I'm not a child!"

Shi Anan listened to his boasting and gave a perfunctory smile, "Fireworks? Haha, this is just the beginning."
