Just as the train entered the vortex, Chen Chu felt a powerful squeezing force coming.

However, compared with the deep-sea channel, the squeezing force of this vortex is much smaller and it is very stable, and the train seems to be traveling through a flowing channel.

Soon the train rushed out of the world channel, and the scene outside the window suddenly changed.

The train looked like a long blue dragon, with light flowing on it and a howling wind sweeping up its body. It was hovering two meters above the ground and moving rapidly, with the base buildings on both sides constantly retreating.

At this time, the time in the mythological world is still dark, but under the silver moon and the street lights between the buildings, many mechanical equipment can be seen operating and producing.

At the same time, in the distant sky, science fiction-style fighter planes kept taking off and landing, and some transport planes even had a wingspan of more than 100 meters.

The transport planes that took off with runes flashing on their surfaces had anti-aircraft weapons installed on their wings and bellies. At the same time, there were giant flying beasts with a wingspan of over 100 meters following them on both sides.

On the backs of these giant flying beasts, there are practitioners wearing armor standing to provide protection.

In the distance, at the end of the darkness, the mountains on the earth are undulating, and towering ancient trees that are hundreds or even thousands of meters high stand like mountain peaks.

In these towering forests, one can vaguely see giant beasts that are over fifty meters long and covered with gray scales, resembling giant rhinos.

At the same time, Chen Chu in the carriage only felt a desolate and distant energy of heaven and earth coming towards him, the concentration of which was almost dozens or hundreds of times that of Wujiang City.

Although the giant beast clone had entered the mythological world before, compared to the doomsday-like Black Oblivion Territory, the human territory was full of vitality and civilization.

As Chen Chu looked outside curiously, the train rumbled through dozens of kilometers and slowly stopped at the platform after arriving at the other end of the channel city.

"We have arrived at Myth City No. 1. Passengers who need to get off please get off in an orderly manner. The next stop of the train is the Sky Curtain Battlefield, which will depart in ten minutes."

Following the electronic announcement, the doors of more than a dozen carriages in the front and middle section of the train opened, and hundreds of young and middle-aged people got off the trains, each of them exuding the aura of a high-level practitioner.

Apparently, Chen Chu was not the only one taking this train.

After these people got off the car, more than ten energy-suspended flying cars over five meters long with yellow runes flashing underneath appeared in the distance, and the people in the cars shouted.

"Those who are going to the Fourth District Assembly Department, get in the car, hurry up."

"Here, here, those who are applying for the Missile Inscription Engineering job, come over here."

"I'm in the behemoth material smelting department..."

Just as Chen Chu was looking at this scene curiously, a diamond-shaped white fighter plane with a wingspan of more than 20 meters and an imprint of two crossed swords fell from the sky in the distance and landed on the temporary airport.

Puff! The door of the fighter plane opened, and a handsome young man who was prettier than a woman walked down. He arrived at the platform in a few flashes and smiled slightly.

"Brother Chu, long time no see."

"Brother Qingqiu." Chen Chu was a little surprised. He didn't expect that Qingqiu Minghui would come to pick him up.

At this time, Qingqiu Minghui's aura was even stronger, and the energy of heaven and earth naturally gathered around him, vaguely forming fuzzy white fox tails.

More than two months later, he, who was only one step away from breaking through the seventh level, has now broken through to the eighth level after his bloodline awakened.

Qingqiu Minghui smiled and said, "Brother Chu, let's get on the fighter plane first. The development department is a few hours away from here."

"Okay." Chen Chu nodded.

Unlike Xie Chen's king-exclusive fighter with a spacious internal space, Qingqiu Minghui's fighter is a standard energy fighter.

Half of the interior space is used to load weapons and ammunition, and the activity space is only more than ten square meters, which is separated from the front cockpit by a few seats.

Whoosh! ! With the hot engine air waves below, the fighter plane soared into the sky under the powerful anti-gravity thrust, and soon rose to an altitude of tens of thousands of meters.

Above the clouds, a transport plane with flashing signal lights was overtaken by a fighter plane from time to time.

Sitting in the driver's seat and setting up the cruise flight, Qingqiu Minghui asked: "Brother Chu, you should have read some information about the mythological world before coming here."

Chen Chu, who was sitting in the co-pilot seat, nodded: "I've read the basic introduction materials."

"It's good that you've seen it. I won't say much more." Qingqiu Minghui said with a smile.

Currently, the largest world channels of the three major empires of the human race and the world channels controlled by more than a dozen medium-sized countries are all under the control of the Federation.

The whole area is shaped like a trumpet cylinder, about 20,000 kilometers long and more than 15,000 kilometers wide at its widest point, with various dangerous areas scattered throughout.

At the same time, this area is a natural danger zone, with broken areas of the world on both sides that even the king of heaven cannot cross. While blocking the human race, it also keeps the enemy out.

The front-line battlefield facing the Purgatory Clan is more than 10,000 kilometers long, separated by death zones where many kings would perish.

As for the Development Department, it was located behind the trumpet tube, and the battle line was several thousand kilometers long.

This area is full of various dangerous areas, and only four entrances are relatively stable. They are used as the bases of the four legions of the expedition department and are explored slowly.

Currently, most of the area between the front-line battlefield and the expeditionary department, which is comparable to the size of the Blue Planet, has been explored by the Federation, including ruins and resources.

In addition, those dangerous high-level beasts and even mythical beasts were swept away and killed by the strong human beings, so the rear area is relatively safe.

Of course, this safety is only for high-level strong people.

Because there are too many mutant beasts and they are reproducing too quickly, there are currently only specific train routes in the rear, and the flight transport routes are safe areas.

Once ordinary high-level practitioners step out of the designated range, they may be devoured by the mutant beasts in the vast forest.

At this moment, the speed of the fighter plane suddenly dropped, and then endless black clouds spread in the left front. Qingqiu Minghui's expression suddenly became slightly serious.

"That black cloud covers an area of ​​more than a thousand kilometers. It is a dangerous area with distorted space. The black fog can block spiritual perception and vision. It is very mysterious."

"Except for the king who went in to explore, no matter if it was the curious practitioners or the mutant beasts, once they went in, they never came out again."

Chen Chu's expression suddenly froze.

This is the horror of the mythological world. It is full of dangerous places. Once you go in out of curiosity or carelessness, you may never be able to get out.

Soon, the fighter plane passed through the edge of the black fog area and arrived above an endless forest with towering trees standing tall.

Roar, roar, roar! ! Fierce roars could be heard from the forest from time to time.

Whoosh! At this moment, a group of more than ten mutant birds with a wingspan of more than 30 meters appeared in the sky. After seeing the fighter plane, they let out a sharp cry and rushed over.

"Looking for death." Qingqiu Minghui looked coldly.

Without the need for Qingqiu Minghui's control, the fighter's automatic defense firepower was turned on, and the energy weapons on both wings instantly shot out beams of light that pierced the night sky.

BANG BANG BANG BANG!!

Under the powerful laser weapons, these level 4 and level 5 mutant birds were killed in the blink of an eye, and their bodies with broken heads fell from the sky.

In the mythical world where the energy of heaven and earth is rich, these fighter planes and weapons that combine technology and runes are even more powerful.

Soon the fighter planes passed through the forest. In front of them, mountains as high as ten thousand meters penetrated the clouds. Under the moonlight, they looked like islands floating in the clouds.

Boom! A strong wind suddenly blew from the sea of ​​clouds to the left of the fighter plane, and a dragon-like stone statue over a thousand meters long, made entirely of rock, circled in the sky.

"This mountain range is an ancient relic, but that civilization has been destroyed for who knows how many tens of thousands of years, and only some weathered rubble remains."

"The thing that just flew over was a giant stone statue that contained special powers. It was very powerful and was the guardian of the ruins that have disappeared."

"But as long as we don't enter the center of the mountain range, these giant elephants will not react unless we actively attack them."

Speaking of this, Qingqiu Minghui sighed: "The mythical world is boundless. There are not only giant beasts and demons, but also many forbidden areas and ruins, which are dangerous and mysterious."

"At present, the area we humans have explored is only a small part of the vast area, so I chose to join the Development Department and want to unravel its mysteries bit by bit with my own hands."

As he was speaking, Qingqiu Minghui looked at Chen Chu with suspicion.

"Brother Qingqiu, why are you looking at me like that?" Chen Chu was a little puzzled.

Qingqiu Minghui hesitated and said, "Strange, why do I feel like you, Brother Chu, have become much stronger in just such a short time?"

In Qingqiu Minghui's blood perception, the dangerous aura emanating from Chen Chu was getting stronger and stronger, just like his strength was getting stronger.

Chen Chu smiled and said, "Brother Qingqiu, you must be wrong. How can I become stronger if I sit here without practicing?"

"Maybe I was wrong." Qingqiu Minghui nodded, but there was a hint of suspicion in his eyes.

When he came, Qingqiu Minghui had read Chen Chu's information and knew that he had broken through to the early eighth level.

But when they met before, the oppressive feeling Chen Chu gave him was obviously not as strong as it is now.

In fact, Qingqiu Minghui's feeling was correct. During the time he was talking to Chen Chu, Chen Chu's physique had become even stronger and more terrifying.

As the Thunder Flame Emperor Dragon evolved and transformed, Chen Chu's body grew stronger every moment as its size grew.

Three days later, the strongest force had soared from 1.5218 to 1.8454, which is more than 18,000, almost equivalent to an increase of more than 1,000 points a day.

With such a terrifying increase, Chen Chu's strength was increasing significantly every moment, which caused some aura to leak out.

And just as Chen Chufei was heading towards the development department.

Under the deep sea, the sleeping Thunder Flame Emperor Dragon upgraded his innate power into laws and continued to temper himself. His body size has grown from more than 320 meters to more than 350 meters.

Its huge body lies horizontally on the ground, and its dorsal fin is nearly 100 meters high. Its slender and sharp tail is like a city wall, full of oppression.

In addition, black lightning was wrapped around the black and red monster, exuding a terrible aura of destruction, and every time it jumped, it would leave black traces in the air.

At the same time, between those thick black and red scales, there was a faint golden light flowing, revealing an indestructible and indestructible feeling.

With the fifth evolution and transformation, life leap and level breakthrough, the aura of the Thunder Flame Emperor Dragon became more and more terrifying, like a sleeping world-destroying beast.

In front of the Thunder Flame Emperor Dragon at this moment, the silver dragon with a body length of less than 170 meters was just a child.

On the body of the silver dragon, the red flame formed by eating the top-grade black-molten divine fruit was burning.

Dozens of huge bluish-white scales are suspended around it, emitting terrifying oppression and intimidating all directions.

"Roar! How boring! The great Ceciltia wants to see a river of blood." The giant dragon that was absorbing the energy of the divine fruit lay on the ground in boredom, sweeping its tail.

At the same time, several kilometers away on the dark seabed, the sleeping unicorn tiger Kun and the deep-sea dragon turtle were also undergoing transformation, and their aura was getting stronger and stronger.

At the same time, on the sea surface, in the area of ​​alternating black and white covering an area of ​​one kilometer, time seemed to have come to a standstill, and waves more than ten meters high floated in the air motionlessly.

And just when the main forces of the Dragon Palace giant beasts were in deep sleep and breaking through.

The sea surface more than 2,000 kilometers away was turbulent. A mutant killer whale with a body length of 60 meters and a pitch-black body was swimming under the sea.

Next to the black killer whale, there was a "small" killer whale that was nearly thirty meters long. This small killer whale had a smooth body and looked very beautiful in black and white.

The female killer whale Xiao Ji showed confusion in her eyes: "Chief, aren't we going to prepare crystals for the king? Why are we here?"

There was a look of pride in the third killer whale's eyes.

This is the territory of another mythical beast. Let's gather some information first and kill them when uncle wakes up.

Chief, how do you know that Lord Thunder Dragon King will attack this mythical beast force?

There was confusion in the female killer whale's eyes. She didn't know why her leader was so sure that the Thunder and Flame Dragon King would declare war on another mythical giant beast empire.

The other side has a powerful and boundless mythical beast in charge.

The black killer whale swayed its fins slightly and let out a proud cry.

Because the Dragon King Ceciltia wants to unify the ocean, my uncle will definitely help, because my uncle dotes on the Dragon King Ceciltia very much.

Xiaoji, you came late, so you don’t know that the mythical beast of the Black Oblivion King died because its messenger despised the Dragon King Ceciltia.

The quasi-mythical beast named Tal was so short-sighted that it only asked its uncle to surrender without bringing along the Dragon King Ceciltia, which made it very angry.

It actually dared to despise the great Dragon King Ceciltia. It was unforgivable. After my uncle’s strength broke through, he rushed over and killed it.

Not only was the mythical beast killed in that battle, but the Ceciltia Dragon King also destroyed its dependent civilization, blood flowed like a river, and the entire world became doomsday.

Wow! Lord Thunder Dragon King dotes on Lady Ceciltia so much! The female killer whale immediately showed envy in her eyes.

The black killer whale patted the female killer whale with its huge fin: "Oh, oh, oh!" Don't worry, Xiaoji, I love you too. If anyone dares to bully you, I will bite him to death.

Boom! !

As the female killer whale snuggled up to him, the black killer whale had a smug look in his eyes.

Humph! ! The eldest and the second are two idiots. What's the point of working so hard? To be a whale, you must learn to use your brain, otherwise you will be a laborer all your life.

At this time, the dark shadow of a giant beast with a body length of more than 50 meters appeared in front. The third killer whale's eyes suddenly lit up, and he swung his tail to meet it.

Hi, brother, can we be friends?
