Rebirth: Join the Army with a System

After hearing this, Wang Zhen continued:

"Then you can use flour to make bombs, but don't underestimate flour, it is called a dust bomb.

Its explosive power is not even inferior to that of a gunpowder bomb.

To make a flour bomb, we must first understand its principle. The reason why flour explodes is because the flour particles encounter open flames, resulting in an explosion.

Of course, there is a ratio. When there is 9.71g of flour in every cubic meter of air.

Once it encounters flames, sparks, electric arcs or appropriate temperatures, it will instantly burn and cause a violent explosion.

Of course, under normal circumstances, flour will not explode even if it encounters an open flame.

However, when it diffuses into the air, compared with bulk materials, dust has stronger chemical activity, a larger area of ​​contact with air, more oxygen molecules adsorbed, and a faster oxidation and heat release process. It burns violently in a limited space, forming an explosion.

The production principle is very simple. We first need to make a container..."

As Wang Zhen explained the production method, Li Tianhua's eyes lit up as he listened. He had never thought that such an inconspicuous daily necessities could be made into bombs.

After Wang Zhen finished speaking these things, he looked at Li Tianhua and asked:

"Do you understand? There is still time. Is there anything else you want to know?"

Li Tianhua nodded and said:

"Yes, are there any bombs that sound loud but don't have much explosive power?"

Wang Zhen smiled and said:

"Yes, there are even bombs that only produce smoke and bright light after the explosion. If you slightly adjust it, it will make a loud noise, but it will not have any killing power."

Hearing this, Li Tianhua's face lit up, he nodded quickly and said:

"Yes, this is what I need. Please teach me."

Wang Zhen smiled and didn't ask Li Tianhua what he was going to do.

“For example, there are many ways to make a smoke bomb, and there are many materials. You need to prepare potassium nitrate, sugar, aluminum foil, etc.

Mix potassium nitrate and sugar in a 3:1 ratio and heat over a small flame.

Stir well during the heating process and it is done when the color turns to dark brown.

Of course, if it starts to smoke while you're stirring, turn down the heat.

Then, use some charcoal, sulfur, and other materials to make homemade explosives.

After being evenly mixed in a ratio of 1:3:5, this gunpowder will produce an explosion sound, but in fact the explosion power is very small.

Of course, these materials are hard to find, you can also use plastic, sawdust and other materials..."

After hearing this, Li Tianhua was greatly inspired and he really wanted to try it now.

However, he knew that he could experiment with this later. Time was pressing now, and every minute and every second was equivalent to what he gained with energy.

He couldn't bear to waste it like this.

After explaining the knowledge that Li Tianhua needed, Wang Zhen asked again:

"Do you have any questions?"

Hearing this, Li Tianhua did not answer directly but began to ponder.

Only a little over an hour has passed since I started studying.

There is still a lot of time left. It is impossible for him to waste all this time!

You know, he spent 500 points of energy to gain this time.

If it is really wasted, I will be heartbroken.

Thinking of this, Li Tianhua asked directly:

"Can you please pass on all your knowledge to me?"

When Wang Zhen heard this, he couldn't help laughing. What a greedy guy.

Then, Wang Zhen said:

“It’s not impossible, but I find that your foundation is very weak. A lot of the knowledge involves advanced physics and chemistry.

Even if I tell you, you probably won't understand.

There are many bombs that require sophisticated instruments to make. Because there are no tools here, I tell you, you don’t understand how to operate these instruments.

The most important point is that you only have less than 24 hours. There is a lot of profound knowledge that I cannot finish explaining to you in such a short time even if I were to explain it to you."

After hearing this, Li Tianhua frowned.

"How about you try to tell as much as you can?"

After listening to what Wang Zhen said, Li Tianhua also realized that relying solely on explanations has many limitations.

But he still wanted to learn more knowledge. After all, this opportunity was rare.

Seeing that Li Tianhua wanted to learn more so much, Wang Zhen did not agree to Li Tianhua's plan.

“How about this, I will just give you the notebook that I have kept of all these years.

Try to learn as much as you can during this time.

what do you think? "

When Li Tianhua heard this, his eyes lit up instantly.

This is good!

Reading is much faster than listening, and even if he doesn't understand, he can memorize the content with his strong memory.

I can study it slowly when I have time.

"Okay, thank you, Teacher Wang!"

This was the first time Li Tianhua called him teacher sincerely.

Even though he was a virtual person, Li Tianhua called out without hesitation.

Wang Zhen smiled with relief after hearing this, and took out a thick notebook from his arms and said:

"Okay, I won't waste your time. I'll give you this notebook. How much you can learn from it depends on your luck."

After taking the notebook, Li Tianhua thanked him again.

"Thank you, I will remember you!"

Then, Li Tianhua opened his notebook and looked at it.

This notebook records things in a very regular pattern.

It covers everything from the simple beginning to the advanced knowledge later on.

Not only that, it is also recorded in great detail, including various experimental reports, conclusions, etc.

Even those high-tech precision instruments have detailed instructions for use.

Li Tianhua looked at the introductions to the instruments. He didn’t know whether these instruments existed in Daxia, but he still wrote them down.

Although there is no method for making these instruments, at least we can understand what they do and what the principles are.

With this limited knowledge, maybe it can be restored through other people.

Over the years, the development of the Great Xia Kingdom has been quite good.

Although many areas are not as developed as those in Western countries, some of our individual technologies are at the forefront of the world.

With these theoretical inspirations, maybe we can create it!

After all, thought inspiration and direction are very important.

With these, it is much easier than to study it all over again by yourself.

Because even in scientific experiments, many of them end up in vain due to the wrong direction.

And what he did was to determine the general direction of the plan.
