Many of the students have studied "Cosmology" and have a certain understanding of the structure of the vast world. They nodded thoughtfully.

However, some people have not studied it in depth. Although they know the existence of the Great Thousand World, they do not understand why the two Great Thousand Worlds collided together.

Outside the Tianyuan Realm is the vast starry sky, and the nearest galaxy is tens of thousands of light years away. It is unimaginable how the impact occurs.

Seeing these students showing confused expressions, Mao Feng further explained:

"Yes, from a three-dimensional perspective, all the worlds are all in the same sea of ​​stars~ they are just many galaxies in the universe."

"Our Tianyuan Realm is one of the galaxies, and the Blood Demon Realm is another galaxy."

"Theoretically, there are no barriers between all the worlds. You can sail freely. What blocks us is just a long distance."

"Using the current technical level of the Tianyuan Realm, it may take millions of years to refine a crystal warship that can navigate the universe."

"Spend a few billion or tens of billions of years to reach the Blood Demon Realm."

"From the three-dimensional perspective, the Tianyuan Galaxy and the Blood Demon Galaxy are mostly half a universe apart, and the distance is very far away, and it is impossible to have a collision."

"But if you look beyond the three-dimensional level, it's completely different from a higher dimension."

"In a higher dimension, each Great World is like a closed egg, closely arranged in a way that we cannot understand, and two eggs that are too close will produce attraction, colliding with each other, and even eventually merge together to form a new Great World."

"And our Tianyuan Realm is too close to the Blood Demon Realm and attracts each other, forming a two-world system."

Seeing that many people still didn't understand, Mao Feng thought about it, took out a blank piece of talisman paper, and drew a circle on the opposite sides.

"Did you see this talisman paper, which is a two-dimensional sea of ​​stars. These two circles that are far away are the Tianyuan Realm and the Blood Demon Realm."

"In the two-dimensional universe, these two worlds are very far apart. Not to mention collisions, even if they sail together, it is impossible."

"But--"

Mao Feng folded the talisman paper in half, and the circles that were originally on both sides overlapped together.

"If there is a powerful force that can break the void and break through the laws of the two-dimensional world. To understand this universe from the three-dimensional level, you will find that these two worlds are close."

"That's how our relationship between the Tianyuan Realm and the Blood Demon Realm is."

"As galaxies, we are at one end of the universe, separated by billions of light years."

"But as the world, on a higher dimension, we are like these two circles. We are very close, creating gravity, hitting hard, and pressing tightly together."

"Maybe one day, the two circles will merge into one!"

"Okay. As a combat cultivator, it's enough to know so much."

"Leave the more in-depth theories to research-oriented cultivators to explore!"

"Anyway, you just need to know that the Dark Realm is the collision point between the Tianyuan Realm and the Blood Demon Realm. The spiritual energy of the two worlds meets here, making this place the most abundant, violent and chaotic place among the two worlds!"

This principle is extremely simple and can be understood by everyone at a glance.

It's like the intersection of two oceans, the undercurrents at the bottom of the sea are mixed with rich resources, all of which are gathered together.

Mao Feng continued:

"The vital energy that was so abundant that it was almost violent, condensed into various treasures of heaven and earth and crystal stone ore veins, and also nurtured extremely powerful mutant monsters and demonized plants, making this place an inexhaustible treasure house!"

"But--"

"The resources in the Dark Realm are so rich, but they are too far from the Federal Inland, and the psychic energy surge is too violent, which is not suitable for large-scale formations of crystal warships."

"Forcibly launch a large army here. If you are not careful, you will be involved in the psychic vortex, and the entire fleet will be torn to pieces!"

Everyone couldn't help but recall the lightning and thunder that had last night.

It was not ordinary lightning, but the violent tides that erupted from the psychic energy of the two worlds violently collided together.

With the refining level of the Tianyuan Realm, the crystal warships refined are indeed unable to navigate such psychic tides.

In reality, war is not about playing games, but about spending a lot of money.

A large fleet was dispatched once, and countless crystals and resources were consumed.

If such a fleet was torn apart by the psychic tide after a long journey, I was afraid that the federal military expenditure would be spent for more than half a year and would be reimbursed in one go.

And this does not include personnel losses.

This is also the reason why the Starry Federation still has not completely conquered the dark realm after five hundred years of bloody battles.

Their biggest enemy is not the demon clan, but nature, this unparalleled world!

"Listen to everyone, no matter how powerful the crystal warship is, it is impossible to gallop across the dark realm. Here, cultivators, especially our armor masters, are the bosses and the main force of war!"

Everyone was so excited that Mao Feng said that, and they wanted to start fighting happily in the dark realm in the next second, hunting monsters, plundering treasures, and madly improving their strength.

Mao Feng pressed his hands down, calming everyone's restlessness and continued:

"This is roughly the case in the dark realm. In the next month, everyone will fight and practice here and get all the treasures of heaven and earth that are 28 cents of the training camp. One percent of them is the loss of crystal armor, and the other part is the commission of us instructors. Is there no problem?"

Everyone nodded.

The crystal armor is provided by the training camp. If it is damaged, it will cost a lot of money to repair it. Of course, it will have to pay a certain amount of loss.

As for giving commissions to instructors, it is even more natural.

The five instructors are all powerful people at the mid-level or above the foundation building stage. After wearing the powerful new model of crystal armor, they can even exert terrifying strength close to the powerful Jindan!

It is under the protection of these five "quasi-golden elixirs" that everyone dared to let go of fighting and practicing in the dark realm.

Otherwise, if a group of small things in the Qi Refining Stage run to the Dark Realm to practice, wouldn’t that be seeking death?

It is really worthwhile to give only 10% of these "quasi-golden elixirs" commissions.

Mao Feng nodded, suddenly changed his mind and said:

"Okay. Since everyone has no objection, we will start practicing next, but there is one thing we want to remind everyone before practicing."

"In the dark realm, there are many crises, the number of thunderstorms and sandstorms is ten times higher than that of the outside world, and the intensity is also equal."

"There are also various powerful mutant monsters, lying dormant in the dark, and they will treat us as prey at any time."

"And these are not the most terrifying."

"The most terrifying thing is the infiltration team of the demon clan, all of which are elites in the regular army of the demon clan. Some infiltration teams are even composed of the silver blood demon clan!"

Mao Feng's words made everyone take a breath of cold

In his heart, Li Yao silently recalled the composition of the demon clan.

Unlike humans, the demon race is not a real race. It is a collective name for countless monsters.

The differences between many of the monsters are even greater than those between monsters and humans.

For example, some mammal monsters, especially primate monsters, such as monkey monsters, ape monsters, etc., have very little differences from humans.

However, the difference with arthropod monsters like the Golden Armored Swordman is huge.

How could a monkey treat a cockroach as a kind of person?

Even this cockroach has a certain amount of wisdom!

Not to mention, many monsters are originally natural enemies. In the food chain, they are all tied up and one after another, swallowing each other and fighting for billions of years. In their bloodlines, deep hatred is engraved.

Therefore, since the Monster Beast Empire 40,000 years ago, the powerful demon clan has been using high-pressure rule, using extremely cruel methods to suppress the weaker demon clans, making them surrender, enslave and drive the weaker demon clans.

After 30,000 years of development, four classes were born in the Monster Empire.

The lowest level is the Black Blood Demon Clan, with the largest number, acting as food, farmers and cannon fodder.

Monsters such as the Black Armored Swordman are the Black Blood Demon Clan.

They are the main force invading the Tianyuan Realm and are inexhaustible. They are inexhaustible to get cannon fodder. Even if they die, the top leaders of the Blood Demon Realm will not feel distressed.

Above the Black Blood Demon Clan is the Copper Blood Demon Clan, which is the class of warriors.

The six-armed snake demon Li Yao encountered in Qingze City is the bronze blood demon clan.

They began to practice killing as soon as they were born. The meaning of life is fighting and destruction, and they often act as commanders and commandos on the front line.

Above the Copper Blood Demon Clan is the Silver Blood Demon Clan.

The Silver Blood Demon Clan is the nobles, royal clans, the ruler of the monster world, and the main force of the demon civilization.

It can even be said that the real demon clan is above the silver blood!

The copper blood and black blood below were just their slaves, cannon fodder and food.

In their eyes, there is no difference from humans, and it is even worse than humans.

After all, humans can create brilliant civilizations, and many of them are also very useful to the demon race.

As for the Golden Blood Demon Clan, it is also called the Holy Blood Demon Clan, which is the real royal family.

The Monster Empire ruled the Star Sea for 30,000 years and replaced more than a dozen dynasties. The royal families of these dozen dynasties have all used massive resources to improve their bloodlines and strengthen their own strength, so they are known as "Holy Blood".

However, during the dynasty change, these holy bloods slaughtered each other.

After the establishment of the Xinghai Empire, the emperor focused on chasing these holy blood demon tribes and almost killed them all.

Until today, the Holy Blood Demon Clan has become a legend, and there may not be one in the entire blood demon world.

At present, the situation in the blood demon world is that the Silver Blood Demon Clan has established hundreds of demon cities, killed and annexed each other, and gradually formed a powerful demon country.

The infiltration team consisting of all the Silver Blood Demon Clan is equivalent to the "Imperial Guard" composed of all the noble children. The terrible degree can be imagined. (To be continued...)
