Doomsday: Humanity shrinks 100 times

Chapter 42 Physical Explosion
Several people were dumbfounded. When they realized what was happening, they were all scared and broke out in cold sweats, looking at each other in bewilderment.

"Wow, that's amazing, it can actually explode." Wu Xiao expressed shock.

"Fortunately, we threw it away in time, otherwise we would be in trouble," Zhang Xinyue said with lingering fear.

"Let's go and take a look." Lu Yuning took the lead and walked towards the place where the explosion occurred.

He stretched out his hand to signal the others to stay where they were, took out his shield, and slowly approached the explosion point.

Although Lu Yuning had a rough idea of the principle of explosion, it was still better to be cautious.

He took three steps and stopped three times, and finally stopped at the explosion point after confirming that there was no danger.

The pile of rust was scattered on the ground, but the plastic material that wrapped it was gone.

The four people behind him saw him squatting on the ground for a long time and ran over.

"It doesn't seem to be that powerful." Zhang Xinyue looked at the ground where the explosion occurred.

"Well... if it was before it shrunk, it would be true. However, for us at our current size, the power is still quite amazing. After all, it can even blow up the plastic shell." Lu Yuning reminded.

Zhang Xinyue suddenly realized that she had forgotten about this.

However, Lu Yuning was still confused about something and asked:

"Old Zou, I hope you didn't touch the rust inside just now. I remember it was sealed when I gave it to you."

"No, no, it started shaking as soon as I took it, but I did use my supernatural powers subconsciously." Zou Yunxin recalled what happened just now.

"In other words, iron products can react without being touched?" Lu Yuning paused and said.

"Is it possible that your supernatural powers don't require direct contact?" Zhang Xinyue said uncertainly.

Lu Yuning was stunned. Perhaps this was really possible.

When they first discovered their superpowers, they subconsciously thought that they had to touch objects with their limbs to activate them. Looking back, it seems that they had never experienced this situation.

With this idea in mind, Lu Yuning and Wu Xiao hurriedly tried it out.

Finally confirmed this conjecture.

Their powers can indeed be activated without contact with objects, but their effectiveness decreases exponentially as distance increases.

This discovery is extremely important to them, and it can be said that it has increased the operational space for supernatural powers.

Moreover, Lu Yuning guessed that as his supernatural powers improved, the controllable distance would also increase.

The specific application methods can be developed slowly in the future, but for now we still need to understand this explosive capability.

"This should be a physical explosion." Zhang Xinyue looked at the rust scattered on the ground.

"Yeah, I noticed it too. I didn't see the fire just now." Lu Yuning nodded.

"What is a physical explosion?" Zou Yunxin asked without understanding.

"You don't even know this, that's not good, Old Zou." Wu Xiao patted his shoulder with a smug look on his face.

"It's enough for Xinyue to know." Zou Yunxin said confidently.

Wu Xiao was suddenly speechless.

"Xinyue, you say it." Zou Yunxin was a little proud.

Zhang Xinyue rolled her eyes at him but still explained, "There are three types of explosions: chemical explosions, physical explosions, and nuclear explosions."

"Not to mention nuclear explosions, the energy of chemical explosions mainly comes from chemical reaction energy."

Hearing this, Zou Yunxin became even more confused and obviously still didn't understand.

"...Okay, let's take an example, like an explosion caused by gunpowder. Because the explosion is caused by the combustion of gunpowder, and combustion is the most common chemical reaction, it's a chemical explosion."

Zou Yunxin nodded slightly, seeming to understand. "What about a physical explosion?"

"The entire explosion process is simply caused by a physical change, such as a sudden change in the state or pressure of an object. The most common example is a balloon exploding."

"Oh... I think I understand now. This little device is like a balloon. The rust inside has burst the outer material."

"Of course, Lao Zou, you're not that stupid." Wu Xiao patted his shoulder.

"Bullshit, I just don't like studying, okay? It doesn't mean I'm not smart." Zou Yunxin glared at him.

Zhang Xinyue ignored them and continued to explain:

"The principle of this bomb is that the potential energy of the rust material inside is rapidly converted, exceeding the bearing capacity of the outer container, and then an explosion occurs."

Lu Yuning nodded, but he made a new discovery.

It seems that Zou Yun’s new ability not only works on iron materials themselves, but also on iron-containing oxides like this one, which can generate potential energy. Its application range is suddenly widened.

And if it is a mixture of aluminum and iron, I don't know what effect it will have.
In short, this thing is quite powerful, but its safety is questionable and needs further research.

The device just now started shaking in Zou Yunxin's hand, and it looked quite dangerous.

If you are not careful and the bomb is not thrown out, and your own people are killed first, that would be a bit funny.

"Old Zou, let's try it again." Thinking of this, Lu Yuning quickly pulled Zou Yunxin to try the principle of its explosion.

But how should I try it? I can't just hold it in my hand and see if it explodes...

Finally, he thought about it and decided that since Zou Yunxin didn't need to touch the device with his own hands, why not add an explosion-proof device in front of the device?

After all, the explosive power of this thing is not that strong, so you don’t have to worry too much if you take good protection.

Thinking of this, Lu Yuning immediately prepared himself. A few minutes later
"As if it wouldn't explode if placed on the ground like this."

Several people stood behind a plastic partition, looking at the bomb package shaking slightly behind the plastic partition.

"Then try throwing it out? That seems to be the process just now."

Zou Yunxin understood and carefully picked up the shaking device.

Under the gaze of everyone, he threw it forcefully into the grass nearby.

"boom"

A familiar explosion sounded.

After several attempts, the working principle of the bomb was finally confirmed.

There are two conditions for an explosion.

First, he must leave the range of Zou Yunxin's supernatural power. In other words, as long as he holds it in his hand and keeps activating his supernatural power, it will not explode.

The second is to be subjected to a certain impact force.

This whole process cannot take too long, otherwise it will become ineffective.

For example, if you charge it first, then put it on the ground for a while and then throw it out, it will lose its explosive ability. It is speculated that the potential energy on the rust will automatically dissipate over time, which is the same principle as the automatic heat dissipation of aluminum sheets.

The bomb's explosion was quite powerful. Although it failed to penetrate the concrete floor, it did create several holes in the mud next to it.

With their current physical condition, it would be difficult for them to withstand this impact.

Moreover, the intensity of the explosion is also related to the material of the outer packaging. If it is replaced with a stronger packaging, the power will be greater.

But the prerequisite is that the rust inside has enough energy to exceed the bearing limit of the external container.
