A cloudburst bomb went down.

The underworld was instantly clear.

The kobold, which was originally blocked in the space below, disappeared directly.

Compared with ordinary ammunition, the advantage of blowing up a wave with cloudburst bombs first is that you don't have to worry about any bacteria, microorganisms, viruses and the like.

No matter how awesome the bacteria and viruses are, they will not survive by the cloudburst bomb in the enclosed space.

After the after-effects of the cloud burst bomb explosion disappeared and the soldiers entered the underground space in chemical protective suits, Tang Rui left the temporary headquarters.

He doesn't have to worry about the rest.

Because inside the underground space, there is a vein structure of magic materials, as long as you send an expert down to take a look, you can find it.

Natural magical materials have been found in the underworld, and if the state does not pay attention to the underworld, then he will not be able to do anything.

But that's not possible.

With the scarcity of minerals in the country, the country will not take action when it is discovered that the underground world, a resource-rich place, will not take action?

Don't forget, we are professionals.

With Tang Rui's withdrawal, the military top brass directly took over the command.

Needless to say, the next thing is that even the equipment that is still in the experimental stage has been taken.

The mechanized infantry regiment opened the way, the sappers then carried out the construction of fortifications, and the field troops stationed the fortifications and advanced step by step downward.

In the later period, the construction speed of the engineer could not keep up, and the military department directly transferred the rocket force engineering unit that built the underground nuclear Great Wall.

This is the only engineering unit in the world at the level of an army group.

Tang Rui also thought that the country would talk to the creatures of the underground world, but how could he ......

We didn't encounter intelligent creatures, they were all monsters.

Crushed all the way through.

When the low-magic world encounters the technological world in the nuclear energy era, it is a situation where it is crushed.

While some magical magic, it can cause some trouble.

But with a rocket passing, all the troubles are solved.

I can't solve the magic problem.

But I can deal with people who do magic.

……

"Everyone's a chicken thief, aren't they?"

Tang Rui's feedback from the magic array of the global underground world and the surface passage, many countries across the country have found the passage.

After all, domestic actions can't be hidden, as long as you use your brain to think about it, you can guess that your own house should also have a channel to connect with the underground world.

With the current level of human science and technology, the rock layers of tens of meters on the surface and under the ground cannot block the detection wave at all.

In this way, countries have discovered their own channels one after another.

But it's one thing to find out, it's another thing to get through.

After opening up, entering the underground time to open up the territory and dig up resources is another matter.

It's not that it can't be done, but it takes time.

As the underground world continues to be discovered, the passages of some small countries have been occupied by warlords.

And then it also gave birth to an industrial chain.

That is to capture the creatures of the underworld, whether they are kobolds or two-headed man-eaters, as long as they are alive, they can be sold for money.

Of course, the most valuable thing is the Drow Elf.

On the black market of the dark web, the price of Drow Genie has been sold for $50 million.

But the dark web belongs to the dark web, and on the bright side, all countries in the world, whether it is a big country or a small country, whether it is the media or the Internet, have not reported anything about the drow elves in the underground world.

It's not just the drow elves, anyway, in all the reports, in addition to the mineral resources in the underground world, the rest are monsters.

And it's an evil and terrifying monster.

Countries around the world have tacitly agreed to block information.

"Good and orderly, neutral and good, chaotic and evil...... The human group has taken up all the camps, and there are all kinds of strange things. ”

Looking at the news on the Internet, as well as some news on the dark web, Tang Rui pouted.

None of these things have anything to do with him.

He is just watching the fun, he is the one who digs the pit, and it has nothing to do with him.

Anyway, the current trend is similar to what he thought.

"Speaker, this is some information captured by the military from the underground world, and after being analyzed and sorted out by experts, it was sent over."

In the office of the school's laboratory building, Sister Zhao walked in with a pile of documents.

"Captured materials from the Underworld?"

After Tang Rui took the document, he looked through it curiously.

I took this pile of information, and it was all related to magic.

[Ignition], [Corrosive Spray], [Negative Energy Tentacles], [Pain Deepening], [Bloody Tribute]......

Tang Rui looked at the translated magic materials in front of him and was very curious.

He also experimented with a few of them.

It's a pity that the name is very nice, but the strongest magic is only the second-ring magic, and it is also a spell.

Most of them are zero-ring spells, and a few one-ring spells are also biased towards negative energy.

"Sister Zhao, look, I said that I am an arcane master, but you don't believe it.

The monsters over there use magic, and they don't understand technology, now you believe it. ”

Tang Rui used negative energy tentacles to make more than a dozen tentacles composed of negative energy fly around, and then said to Sister Zhao with a smile.

"Believe, of course believe, if it's okay, I'll go first." Sister Zhao said with an embarrassed but polite smile.

She was not surprised that Tang Rui was able to use these magics.

Because after reading these materials, Yang Lao can also use some magic, but he doesn't learn it as quickly as Tang Rui.

As for the Underworld, there is no technology, but it is able to use magic.

Yang Lao also gave his own explanation.

Technology is the use of devices to observe the world and collect information.

Just like wave-particle duality, the state of a particle depends on the means you are observing.

The same goes for the magic element, if you use scientific and technological equipment to observe, the results are completely different from those observed with mental power.

The superposition of quanta is like this, how you observe, how the particles feedback.

The magic of the underground world is the means by which they use their spiritual power to observe the world, summarize the knowledge obtained from the world's feedback, and study it.

In the final analysis, they are all studying the rules of the world, but the methods are different, and the means are different.

It is precisely because of magic that the countries have completely exterminated the underground world.

If the underground world plays with technology, and the level is not as high as the surface level, it may be a different situation, and maybe they can coexist peacefully.

But if you play magic, it won't work.

Hell knows what cards you have and how much you can make a move.

If the underworld is allowed to develop, the people of the underworld will learn knowledge, and in addition, they are born with stronger spiritual power than humans, and they can sense the magic element.

When the time comes, what will they do with their bare hands?

Thanks to Tang Rui's foolishness, everyone has read Western fantasy novels during this time.

In particular, the Arcane Constellation, a system that combines knowledge and power, is very similar to reality no matter how you look at it.

Therefore, since the life of the underworld plays magic and looks different from humans, there is no need for it to exist.

The place where the couch lies does not allow others to sleep soundly.

You're making noise underground every day, so it's no wonder we can sit still on top.
