In the evening, Tang Rui left a phantom at home, and returned to the academy with briquettes and the Book of Ten Thousand Laws.

With the Floating City as a means of transportation, it was more convenient for him to return to the academy than to go to the Demon Capital from Jinling.

Back at the academy, teleport directly to the front of the library.

In an instant, the forces of nature began to converge towards him, and the surrounding plants all exuded fluctuations of joy.

"It's still comfortable on the High Demon Plane."

Feeling the active magical elements around him, Tang Rui felt that his entire body was soothed.

"Meow...... But it's not interesting here, it's not as fun as Earth. ”

Although Briquettes also likes the High Magic environment, it prefers to play.

"Let's go, let's go to the Plane Archives first."

"Meow...... Come with this king. ”

The briquette rode the Book of Ten Thousand Laws and led Tang Rui to the plane archive room in the library.

At first, Tang Rui thought that this so-called archive room should be the kind of place full of bookshelves and safes.

As a result, when he entered the Dimensional Archives, he saw holographic projections.

It is a phantom space that simulates the astral ocean.

"Meow...... This is the record archive of that plane. ”

The briquette grabbed a small plane from the simulated astral ocean and handed it to Tang Rui.

"Name: Checkerboard Plane

Number: Small-77351

Energy Level: Low Demon Plane

Plane Awareness: Clear (crossed out) has no plane awareness

Deity Level: Primordial deities are used (crossed out) without deities

Details: The plane discovered during the random cross-plane teleportation experiment is a plane with a double-layer space structure, which is divided into two layers: ground and underground.

There are the remains of seven (scratched) gods, (scratches) no native plane consciousness has been found, and there are many races in the plane, among which there are dragons with the blood of the higher dragon clans, which are very suitable for putting (crossing out) magic pets.

Summary: There are no planes with much potential, no special resources, no need to develop. ”

After reading this archival record, the corners of Tang Rui's mouth twitched unconsciously.

Because in this archival record, he found deep malice.

Those scratches, and those words that are crossed out, even a fool can guess what the content is.

The god of this small plane was captured, the plane consciousness was killed, and the dragon with the blood of the higher dragon clan was captured and bled out.

"Briquette, can you now know what's going on on this compass plane?"

After reading the archival records, Tang Rui asked again.

"Well, it's an image from a plane altar."

The briquette waved its hand, revealing an image.

In this image, a group of ragged, gray-faced people are kneeling under the altar, praying incessantly.

There were no sacrifices, the offerings were some books and a mess of things.

Anyway, the whole sacrifice looks very informal.

"Lord of the Great Tower of the Nine Rings, I beg you to shelter us, to keep us away from here, from the evil races of the earth, and we want to travel to your eternal realm from war, famine, disease, and death."

Through his knowledge of language and magic, Tang Rui understood their prayers.

But the more this happened, the stranger he became.

That's what it's like.

You fight wars, why pray to the Lord of the Nine Rings Tower.

"Briquettes, they can use this kind of altar to contact the Nine Ring Tower, isn't there any difficulty?"

This means of interdimensional communication is not so simple.

As a result, such a group of refugees were able to contact the Nine Ring Tower.

Tang Rui felt that this was a conspiracy.

"This plane altar was specially established by an arcane master after discovering this plane in order to maintain contact with the academy.

All they had to do was activate the Plane Altar, and there was nothing difficult about it. Briquettes replied.

That makes sense.

Underground races invade the surface, which is a common occurrence in both two-layer and multi-layered planes.

As long as it's not a plane invasion, it's a petty fight.

"What would the academy have done in such a situation?" Tang Rui asked.

"Don't do it, hang up the task, if someone wants to take this task, they will go to that plane by themselves, as for what they can get, it all depends on personal means." Briquettes said indifferently.

There are too many of these small low-demon planes in the entire Astral Ocean.

Especially with this lack of resources...... Well, the plane where the resources were looted by the first big guy to enter, few people would be interested in it.

In this illusion space alone, the number of small planes that Tang Rui could see exceeded hundreds of thousands.

These are all captured in the astral ocean by the arcanists, constantly using astral projections.

Therefore, the academy does not attach importance to these planes.

"Well...... You go to hang up the task, and I take this task. ”

Tang Rui thought about it and decided to go to that plane to have a look.

Not on his own, of course.

Instead, he took briquettes and the Book of Ten Thousand Laws, and drove the floating city to take a look.

Regardless, safety first.

Controlling the Floating City, Tang Rui came to the crystal wall of this plane, suspended in the astral ocean and quietly observed.

"Briquette, looking at it like this, this plane is not invaded by the outside world, it should be an internal problem."

"You've made the Floating City circle around this plane three times, aren't you sure?"

The briquettes were speechless.

I've seen people who are afraid of death, but I've never seen Tang Rui so afraid of death.

You're in the Floating City, what are you afraid of?

Even if the gods come, you don't have to be afraid.

"Since it's okay, let's go to the plane."

Tang Rui didn't feel embarrassed, although he was a little cowardly, but there was only one life, and there was nothing wrong with being cautious.

After the floating city entered the chessboard plane, the spatial fog was opened.

In a low-demon world where there are no gods, no demigods and legends, and the highest strength is only at the level of an intermediate magician, no one can discover the Floating City.

"The humans of this world are almost finished?"

Entering the interior of the surface, Tang Rui found that the war between the surface and the underground in this world was not a stalemate, but a complete rout on the surface.

Whether it is on the huge continent in the center of the plane, or the giant islands around the continent, the human city-states on the surface are all in a state of passive defense.

Countless underground races rushing out of the underground caverns are frantically attacking the human city-states.

Everywhere he passed, there were corpses all over the field, and not a single grass was born.

"Normal procedure, what should I do at this time?" Tang Rui asked about the briquettes.

"There's no program, whatever you do, if you don't like this plane, just use [Large Plane Collapse] and break this plane into materials."

Not necessarily, not necessarily.

After hearing this, Tang Rui hurriedly shook his head, he was not so cruel yet.

After more than ten years of education, he couldn't do this kind of thing.

As for helping?

Tang Rui looked at the humans below, he really didn't have any idea of wanting to help.

What to do?

After a while, he suddenly had a bold idea.
