Among the students, many of them have studied "Cosmology" and have a certain understanding of the structure of the world, and they all nodded thoughtfully.

However, there are also some people who have not studied it in depth, although they know the existence of the world, but they do not understand why the two worlds collide together.

Outside the Tianyuan Realm, there is a vast starry sky, the nearest galaxy, and the distance is tens of thousands of light years, and it is really unimaginable how the impact will occur.

Seeing the blank expressions on these students, Mao Feng further explained:

"Yes, on a three-dimensional level, all the worlds are in the same sea of stars~, just many galaxies in the universe."

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

"Theoretically speaking, there are no barriers between all the worlds, and we can sail freely, but what separates us is just a long distance."

"With the current level of technology in the Celestial Yuan Realm, refining a spar battleship that can sail in the universe may take millions of years to reach the adjacent galaxy, that is, the world next to us."

"It will take billions or tens of billions of years to reach the Blood Demon Realm."

"From a three-dimensional level, the Tian Yuan Galaxy and the Blood Demon Galaxy are separated by most of the universe, and the distance is very far away, and it is impossible for an impact to occur."

"But jumping out of the three-dimensional level, looking at it from a higher dimension, it's completely different."

"In the higher dimensions, every world is like a closed egg, closely packed together in a way that we cannot understand, and two eggs are too close together. Attraction will be generated, colliding with each other, and even eventually merging together to form a new world. ”

"And our Tianyuan Realm is too close to the Blood Demon Realm, attracting each other. constitutes a two-world system. ”

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

"See, this rune paper is a two-dimensional sea of stars, and these two circles that are far away from each other are the Tianyuan Realm and the Blood Demon Realm respectively."

"In a two-dimensional universe. These two worlds are so far apart that even if they collide, it would be impossible for them to sail each other. ”

"But—"

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

"If there is a powerful force that can shatter the void and break through the laws of the two-dimensional world. If you comprehend this universe on a three-dimensional level, you will find out. These two worlds are close at hand. ”

"The relationship between our Heavenly Yuan Realm and the Blood Demon Realm is like this."

"As galaxies, we are at one end of the universe, hundreds of millions of light-years apart."

"But as a vast world, in the higher dimensions, we are like these two circles. Very close, creating gravity, striking hard, clinging together. ”

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

"Alright. As a combat-type cultivator, it is enough to know so much. ”

"For more in-depth theories, leave it to research-type cultivators to explore!"

"Anyway, as long as you know that the Dark Realm is the collision point between the Tianyuan Realm and the Blood Demon Realm, and the spiritual energy of the two worlds converges here, making this the place with the most abundant spiritual energy, the most violent, and the most chaotic of the two worlds!"

This truth is extremely simple, and everyone can understand it at a glance.

It's like the confluence of two oceans, where the undercurrents of the ocean floor are mixed with abundant resources, all of which come together.

Mao Feng continued:

"The abundant spiritual energy is almost violent, and it has condensed into various heavenly and earthly treasures and spar veins, and has also bred incomparably powerful mutant demon beasts and demonized plants, making this an inexhaustible treasure house!"

"But—"

"The resources of the Netherlands are so abundant, but they are too far from the interior of the Federation, and the psionic energy surge is too violent to be suitable for a large-scale hedron warship formation."

"Forcibly deploy a large force here, if you are not careful, you will be caught in the vortex of psionic energy, and the entire fleet will be torn to pieces!"

Everyone couldn't help but recall last night's lightning and thunder.

It was not ordinary thunder and lightning, but a violent tide that erupted from the spiritual energy of the two worlds violently colliding together.

With the refining level of the Heavenly Yuan Realm, the spar battleship refined could indeed not sail in such a spiritual energy tide.

War in reality is not about playing games, it's about burning a lot of money.

A large fleet can consume countless hedrons and resources once it is dispatched.

If such a fleet is torn apart by the psionic tide after a long journey, I am afraid that the military expenses of the Federation for more than half a year will be put in and reimbursed at once.

And this, not counting the loss of personnel.

This is also the reason why the Star Glory Federation has not completely conquered the Dark Realm after five hundred years of bloody battles.

Their biggest enemy is not the demon race, but nature, this powerful and unrivaled world!

"Listen, everyone, no matter how powerful the hedron battleship is, it is impossible to gallop in the dark and boundless realm, here, the cultivators, especially our armor masters, are the boss and the main force of the war!"

Everyone was enthusiastically boiled by Mao Feng's words, and they couldn't wait to start fighting happily in the dark and desperate domain in the next second, hunting demon beasts, plundering heavenly and earthly treasures, and frantically improving their strength.

Mao Feng pressed down with both hands, calmed down everyone's restlessness, and continued:

"The situation in the Dark Domain, that's roughly the case, in the next month, everyone will fight and cultivate here, and all the heavenly and earthly treasures they get will be divided into two or eight accounts with the training camp, one percent of which is the loss fee of the crystal armor, and the other one percent is the commission of our instructors, no problem, right?"

Everyone nodded.

The crystal armor is provided by the training camp, and if it is damaged, it will cost a lot of money to repair it, and of course you will have to pay a certain amount of wear and tear.

As for the commission given to the instructor, it is even more justified.

The five instructors, all of whom were strong people above the middle level of the foundation building period, were even able to exert their terrifying strength close to the Jindan powerhouse after wearing the powerful new model crystal armor!

It was under the protection of these five "quasi-Jindan powerhouses" that everyone dared to let go and fight in the dark and desperate domain. Practice.

Otherwise, a group of small things in the Qi refining period ran to the Dark Peerless Domain to cultivate, wouldn't that be looking for death?

It is really cost-effective to only give these "quasi-Jindan powerhouses" a commission of one percent.

Mao Feng nodded, and suddenly changed his words and said:

"Good. Since everyone has no opinions, let's start cultivating next, but there is one more thing I want to remind you before cultivating. ”

"In the dark and desperate region, there are dangers, and the number of thunderstorm areas and sandstorm areas is ten times more than that of the outside world, and the intensity is not the same."

"There are also all kinds of powerful mutant demon beasts, lurking in the shadows, and they will take us as prey at any time."

"And these. None of them are the scariest. ”

"The most terrifying thing is the infiltration team of the demon clan, all of them are the elite of the regular army of the demon clan, and some of the infiltration teams are even composed of the silver-blooded demon clan!"

Mao Feng's words made everyone gasp

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 kinds of demon beasts.

The difference between many of these demon beasts is even greater than the difference between demon beasts and humans.

Say. Some mammalian monsters, especially primate monsters, such as monkey demons and ape demons, are very different from humans.

And with arthropod monsters such as the golden armor sword mantis, the difference is huge.

How can a monkey treat a cockroach as if it were one of its kind?

Even this cockroach. Have a certain amount of wisdom!

Not to mention, many demon beasts were originally natural enemies, and in the food chain, they were interlocking and interlocking, between each other. devouring each other, fighting for hundreds of millions of years, in the blood, engraved with deep hatred.

Therefore, since the Demon 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, make them submit, and enslave and drive the weaker demon clans.

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

At the bottom, there are the Black Blood Demon Clan, the largest in number, and they are the storage zài who act as food, farmers, and cannon fodder.

Demon beasts such as the Black Armor Sword Mantis are the Black Blood Demon Clan.

They are the main force invading the Tianyuan Realm, and they are also an inexhaustible source of good cannon fodder, even if they die, the high-level leaders of the Blood Demon Realm will not feel distressed.

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

The six-armed snake demon that Li Yao encountered in Qingze City was the Bronze Blood Demon Clan.

They began the cultivation of killing when they were born, and the meaning of life was to fight and destroy, often acting as front-line commanders and commandos.

Above the Bronze Blood Demon Clan, there is the Silver Blood Demon Clan.

The silver-blooded demon clan is the nobleman and royal family of the demon clan, the ruler of the demon beast world, and the main force of the demon civilization.

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

The copper and black blood underneath are nothing more than their slaves, cannon fodder, and food.

In their eyes, there is no difference between them and humans, and even worse than humans.

After all, human beings can create a glorious civilization, and many of them are created, and the demon race is also quite useful.

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

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

However, in the change of dynasties, these holy bloods slaughtered each other.

After the establishment of the Star Sea Empire, the emperor focused on chasing and killing these holy blood demon clans, 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 Realm.

At present, the situation in the blood demon world is that the silver-blooded demon clan has established hundreds of demon cities, killing and annexing each other, and gradually forming a powerful demon country.

The infiltration team composed entirely of the Silver Blood Demon Clan is equivalent to the "Imperial Forest Army" composed of all the children of the nobles, and its terrifying process can be imagined. (To be continued......)
