Rebirth: Join the Army with a System

The various things that happened later are basically the same as the two people above.

Either they are some outdated antiques, or they are some modern people.

The energy they require ranges from 1000 points to 100 points.

After seeing these, Li Tianhua felt that they were a bit expensive. Is this the result of fixed-point selection?

He remembered that medical copies were not so expensive before.

"System, why did the medical dungeon I visited last time only require 10 energy points, but this one requires 100 energy points?"

The system responded in a very human way:

"One is taught by someone, and the other is taught by no one, so you have to rely on yourself. So they are different."

Hearing this, Li Tianhua frowned.

To be honest, he had learned a little bit of basic knowledge before he could start studying medicine.

Bombs require a lot of professional knowledge, and he has never learned the relevant knowledge at all.

Is it possible for him to figure it out with his high school level knowledge?

If we really want to figure it out, we don’t know when it will take.

Although the time in the system is infinite, his energy is limited. He doesn't know what will happen if he goes to a copy at random. It is still unclear whether he has time to study the bomb.

It seems that this still requires professionals to teach.

Then, Li Tianhua asked again:

"Do these people have the technology to remotely control bombs?"

system:

"Host, please rest assured. Whether it is a contact bomb, a remote-controlled bomb, or a time bomb, these are the most basic ones. Anyone who chooses them can learn them."

Li Tianhua looked at the people on the panel and hesitated. He couldn't make up his mind for a moment.

Those who know a lot need several hundred energies, and those who know less need at least 100 energies.

The cost-effectiveness is too uneconomical, the cost is several times or even dozens of times higher than random chance.

If he chooses the cheapest one, he doesn't know whether he can achieve his desired goal.

You know, he only has 710 energy left now, which is not enough to deal with here.

If he chooses less and fails to achieve his desired goal, it is equivalent to wasting one-seventh of his energy.

If he chooses too much and fails to learn all the person's knowledge within the limited time, it would be a waste.

Li Tianhua stared at the energy panel, scanning it back and forth.

After a moment, he gritted his teeth and decided to be safe.

"I choose Wang Zhen!"

"Okay, host, please input the energy into the panel, and you will then receive 24 hours of time instruction from Wang Zhen.

How much one can learn depends entirely on the host.

Of course, you can also extend the time by spending energy.”

After hearing this, Li Tianhua complained, "You're still trying to trick him into spending energy? No way!"

After making his selection, Li Tianhua no longer hesitated and reached out to the panel, transmitting energy.

Li Tianhua felt so distressed watching the energy gradually decreasing!

It’s so heartbreaking!

He worked very hard to earn this energy.

Just like that, more than half of it is gone!

No, Li Tianhua decided that he would never give up until he got his energy back from these drug dealers!

After a short while, the energy was transferred.

There was a change in the space, and Wang Zhen appeared.

When Li Tianhua saw Wang Zhen, he no longer cared about the energy and hurried forward and said:

"Master Wang, thank you for your help!"

Wang Zhen smiled and waved his hand, saying:

“No trouble, very fair deal.

Tell me what you want to learn.

But you have to remember, you only have one day."

Seeing Wang Zhen like this, Li Tianhua was very surprised. This was the first time he found that the person simulated by the system was so real.

Of course, the characters simulated in the past cannot be said to be unreal.

But Li Tianhua rarely has in-depth communication with those people.

That's why it gave him a feeling that it was not real.

Then, Li Tianhua said without hesitation:

"I need to learn how to make remote-controlled bombs now, is that okay?"

Hearing this, Wang Zhen nodded and said with a smile:

"This is simple."

“Whether it’s a time bomb or a remote-controlled bomb, you first need to learn some knowledge about circuits.

Secondly, to remotely control bombs, you also need to learn some knowledge about signal transmission.

After learning these, it will be easy to decide what material to use as the core of the bomb.

For example, cesium is the most active metal in the world and is flammable and explosive.

In the air, it will burn automatically.

It will also explode violently in water.

Cesium is very common and can be extracted even from mineral water with sufficient equipment.

Cesium was discovered by a scientist named Benson. He used a spectrometer to analyze mineral water and found that in addition to the common elements such as potassium, calcium, and scale, there was also an unknown metal, which they named cesium.

When using cesium, we must be careful that it cannot come into direct contact with air.

Because it has a very low melting point, its melting point is only 28.44C, and it will explode after a slight contact with air.

If you want to increase the explosive power of cesium, you can put it together with sulfur. When the two substances come into contact, a chemical reaction will occur and it will turn into cesium sulfide.

Its explosive power is several times, or even dozens of times, that of pure cesium.

The best effect can be achieved according to the ratio of 3:7.

Of course, when handling cesium, we must be careful not to let it come into contact with the air. So what should we do?

To this end, through experiments we found that cesium can be placed in kerosene first.

Because kerosene contains water and oxygen as impurities, cesium will form a gray oxide film when it comes into contact with it.

With this oxide film, we can change cesium from a liquid form to a solid form.

Moreover, its hardness is very low, and it can be said to be the softest solid metal. At this time, it can be easily..."

Wang Zhen spoke incessantly, and Li Tianhua listened very attentively in the audience.

As expected of an instructor who was created through hundreds of energy simulations, he had not expected that such a substance could exist in common water.

In a short while, Wang Zhen learned the methods of circuit manufacturing and signal transmission.

Of course, the production method of bomb materials is also introduced.

"Do you understand these? Is there anything else you want to ask?"

Li Tianhua nodded and asked:

"How can we make a simple bomb when conditions are limited and there is no equipment?"

Wang Zhen smiled and said:

"This is very simple. If you have common flour, this should be available!"

Hearing this, Li Tianhua thought for a moment, nodded, and said:

"some!"
