On the outskirts of the logistics city, eternal saplings stood ten thousand meters tall. The rich energy of heaven and earth around them was like clouds and mist, turning into a golden sea of ​​clouds under the sun.

Some aliens from the Sky Feather Clan were floating around the sacred tree, with two pairs of golden wings spread out behind them, emitting a faint halo that echoed with the sacred tree, and their aura fluctuated.

Between the sacred tree and the logistics city, ten black space-based warships more than ten kilometers long were suspended in the sky, casting large shadows that covered the sky and the sun, filled with an invisible sense of oppression.

Thousands of energy bombers were parked on the battleship's surface deck, and people were moving around doing the final check.

On the black deck in front of the battleship with the word Expedition No. 1 painted on it, the three hundred meter tall, thin and ferocious looking Unit 1 stood covered in black and red armor.

In front of Unit 1, Luo Fei was floating at an altitude of more than 200 meters. He looked very handsome in his gorgeous combat suit with a silver base and red edges.

At this time, strong energy fluctuations permeated the body of Unit 1, and its eyes flashed blue and white light.

At the same time, some dark golden lines appeared on Luo Fei's exposed neck and chin, and the aura on her body, which had reached the peak of the eighth level, was slowly strengthening in response to Unit 1.

At the same time, when the soul fluctuations were in harmony and she was practicing with the help of Unit 1, Luo Fei even had the same terrifying aura of Unit 1 that frightened countless creatures.

At this time, a strong wind was howling in the distance, and an 80-meter-tall black and white mecha flew over, spewing hot air waves behind it and slowly landed next to the No. 1 machine.

The Black Demon White King mecha raised its head, with white light flashing in its eyes, and Gabriella's voice came from inside: "Luo Fei, the higher-ups suddenly issued a notice to delay the departure time by two days."

Hearing this, Luo Fei lowered her head slightly, with a hint of desolation and remoteness in her eyes. At the same time, when Luo Fei lowered her head, Unit 1 behind her, which was in a synchronized state, also lowered its head.

Suddenly, under the gaze of those blue and white eyes, Gabriella felt a little nervous even through the mecha.

Luo Fei whispered, "Didn't you say you were leaving today? Why is it suddenly delayed?"

"It is said that some places are not ready yet."

"Is that so?" Luo Fei nodded slightly.

Looking at the black-haired girl whose aura was somewhat scary and gave her a terrifying feeling of covering the sky and the sun, Gabriella hesitated: "Luo Fei, are you okay?"

Luo Fei's eyes wavered for a moment, and she shook her head slightly: "I'm fine, the lines on my body are the manifestation of refining Unit 1, or reverse assimilation."

The mecha on Simon's body is called a mecha, but in fact it is an extraordinary biotechnology that integrates a large amount of giant beast materials. It is not a simple integration of man and machine.

It is similar to treating the mecha as a complete biological shell and practicing as an external incarnation.

This route is different from the route of combining technology and martial arts that Luo Fei told Chen Chu when he was in the third heaven. No one has succeeded in taking that route yet.

As for the biological mecha route, the strongest one at present is the Sky-based God King. The core material of the super-god mecha on his body comes from an ancient giant beast, so his combat power is very exaggerated.

After breaking through the eighth heaven, Luo Fei began to formally "refine" Unit 1, and because of the synchronization of souls, the two sides were "one", so Unit 1 did not resist.

It’s just that the gap between the two sides is too big. While refining Unit-1, Luo Fei is also being eroded by the power of Unit-1, which is actually an alternative form of assimilation.

It’s just that one is controllable and the other is uncontrollable.

…

Inside the room, the burly Chen Hu sat cross-legged, his entire body covered in black and gold power, emitting a heavy and terrifying aura.

It was as if the person sitting on the ground was not a person, but a huge beast.

Chen Hu held a piece of bronze ore the size of a basin in his hand. The dark star qi and blood in his body flowed, turning into strands of thin qi and blood to form a "net" that enveloped the bronze ore.

The hard and heavy ore under the Dark Star Qi and Blood Net vibrated, and bits of heavy metal elements were transformed by the Qi and Blood Net, wrapped up and entered Chen Hu's body through his hands, and circulated together.

As the overbearing and heavy elemental substance entered, the meridians in Chen Hu's body instantly felt a sharp pain, and he even felt as if he was being cut and crushed.

However, under the protection of the innate domineering body, Chen Hu's meridians, blood and flesh were extremely tough, and the severe pain of his whole body being torn apart only made him frown slightly.

Seeing this, Chen Chu nodded with satisfaction and slowly withdrew his right hand.

Although Chen Hu had been following him around since he was a child, he had always been independent-minded and strong-willed.

However, although Chen Hu broke through the second level of Dark Star Overlord with his help, Chen Chu did not leave. Instead, he sat cross-legged in the back and quietly adjusted his breathing to protect the Dharma.

After all, he is his younger brother, so he still has to be looked after.

Chen Hu didn't know about all this. At this moment, he was immersed in the feeling of becoming stronger through practice. He excitedly circulated his Qi and blood through his body again and again, absorbing the heavy elements from the lapis lazuli ore in his hand.

Because of the awakening of his innate physical body and the change in his physical constitution due to his gigantic talent, Chen Hu's physical body has become extremely strong. In this case, he can achieve twice the result with half the effort when practicing body-refining techniques.

Therefore, every time the dark star power in his body circulates, his blood and qi will double in size. At the same time, his meridians, blood and flesh will become harder under the strengthening of heavy elements.

As time passed, Chen Hu's aura gradually became heavier and more terrifying, and even traces of green lines appeared in the black and gold power covering his body.

boom!

Chen Hu's aura surged, and he broke through the third level of Dark Star Overlord Body, which was equivalent to the triple level of Body Refining and Zhenwu. The powerful force squeezed the surrounding air and created gusts of wind.

At the same time, the bronze ore in Chen Hu's hand made a crackling sound, and with a bang, it turned into gray-white gravel scattered all over the ground.

call!

Chen Hu let out a long breath and slowly opened his eyes. His eyes, sparkling with black and gold light, contained a domineering and arrogant look, as ferocious as a tiger.

At this time, Chen Chu's voice sounded: "Yes, now you have entered the stage of body refining exercises. What you need to do next is to practice steadily."

"Come on, let's go out and have breakfast. I'll be leaving soon after that."

Chen Chu's words made Chen Hu pause. He then noticed that it was already dawn outside the window. The domineering look in his eyes disappeared, and he was a little confused: "Brother, I practiced all night?"

"What do you think?" Chen Chu smiled.

As Chen Chu said that, he opened the door and walked out. Zhang Xiaolan had already prepared breakfast outside.

Looking at the tall Chen Chu and the even more burly Chen Hu following behind, Zhang Xiaolan showed a gentle smile: "Ah Chu, you are out."

"How's it going, Ah Hu? Is your training going well?"

"Mom, my brother is a king. With him protecting me, there's no way an accident could happen."

Chen Hu clenched his right fist, and his thick shoulder and arm muscles bulged with strength. "The skills my brother gave me are very powerful. I feel like I can knock away yesterday's me with one punch now."

"As long as it goes well."

Zhang Xiaolan nodded, and then reminded: "But I asked you to practice, not to fight. Don't rely on your brother to bully others, understand."

"Mom, I know that as long as others don't provoke me, I will definitely not do anything rash."

After teaching Chen Hu a lesson, Zhang Xiaolan looked at Chen Chu again, hesitating slightly: "Ah Chu, remember to be careful when you go there this time."

"I was shocked when I heard the online rumor that you were hunted by some infernal demon and died in the mythical world."

Chen Chu smiled and said, "Don't worry, Mom. I will be careful. As for the rumors on the Internet, don't worry about them."

After Chen Chu disappeared under the pursuit of the three demon gods of Emperor Orus, the other party not only disrupted the morale of the army on the Sky Curtain battlefield, but also spread some rumors on the Blue Star Internet.

However, the news on the Internet was locked at the first time, and then several evil god believers were arrested in a country in Beilin.

But because it involved Chen Chu, the powerful king at the peak of his power, the news spread quickly, so Zhang Xiaolan also heard some rumors.

After having breakfast with Zhang Xiaolan and the others, Chen Chu and Chen Hu went out as usual.

On the side of the road, Chen Hu looked at Chen Chu who was about to leave and said, "Brother, remember to leave two demon kings for me. I will defeat them all after I break through to the king level."

"Okay, I'll leave two for you to practice with." Chen Chu patted Chen Hu on the shoulder, then soared into the sky and turned into a golden light that pierced through the clouds.

On the steps at the door, Zhang Xiaolan looked up and watched the golden light disappear into the sea of ​​clouds, with a hint of worry in her eyes.

Although Chen Chu said that he was fine when he came back this time, the weak feeling on his body that he could not hide, and the white hair on his head that was said to be caused by the martial arts, how could it deceive her?

Obviously after becoming a mythical powerful being, the enemies Chen Chu faced became stronger and more dangerous.

…

A beam of golden light flew past the sea of ​​clouds at a speed more than twenty times the speed of sound, and the sonic boom it created formed a thousand-meter-long tail of air and light behind it.

In just a moment, the fog that covered the sky and the sun spread ahead and they arrived at the edge of the restricted area.

Boom! The space shook violently under the horrific impact, and the golden light directly penetrated the barrier that isolated the outside world and appeared above the base of Channel No. 1.

There, Xie Chen was already standing on the rooftop of the building.

Golden light descended from the sky and Chen Chu's figure appeared in front of Xie Chen.

"Here comes Chen Chu, let's go, let's go to the core area of ​​Tianyu Think Tank first."

Knowing that Chen Chu had something to do, the two of them didn't waste any words. Xie Chen directly took Chen Chu a thousand meters underground to the core of Tianyu Think Tank.

As the intelligent system that connects the entire federation and manages all the core elements, the core body of Tianyu Intelligent Brain has very strict defense.

However, Chen Chu had been here once before and was familiar with the route.

However, when he walked into the empty underground base and looked at the huge Rubik's Cube in the center, blue thunder jumped on Chen Chu's body, and then turned into an electric grid that covered the entire base.

"...What's wrong, Chen Chu?" Chen Chu's behavior stunned Xie Chen.

"This time I not only brought back a technique, but also a virus."

As Chen Chu spoke, his wrist flashed, and more than two hundred ancient cultivation techniques appeared densely, and Xie Chen's eyes narrowed immediately.

In his perception, some faint cell-like substances on those secret books flew out, floated in the air, and spread at an astonishing speed.

Chen Chu said solemnly: "Thank you, Senior. This is a special virus that spreads infinitely regardless of air and liquid media. It can cause organisms, including plants, to mutate and evolve."

"Mutation and evolution, similar to the energy of heaven and earth in the mythical world?"

"There are some similarities, but the mutations of these viruses mainly act on the biological body. They will be more effective when used in conjunction with basic body-refining techniques."

"It's just that these viruses are very dangerous. Ordinary people have a 70% chance of being infected and mutated. If we're not careful, it could lead to doomsday."

Xie Chen suddenly became solemn: "It seems that only we can study this thing ourselves. It is not safe to hand it over to the people below."

Chen Chu nodded: "This is also the reason why I came here to upload the skills."

The virus in the lost world is terrible, even more terrifying than biological viruses. It multiplies infinitely and attaches itself to matter. Under normal circumstances, even the strongest protection will have loopholes.

After testing, Chen Chu discovered that this virus could only be completely blocked by the power of the laws of a mythical strong man.

However, although this virus is terrifying, its effect is also exaggerated. It causes the physical fitness of ordinary people in the Lost World to increase dramatically, and in just a few years their physical bodies can be comparable to those of high-level practitioners.

And those monsters that had completely mutated and lost control evolved into high-level monsters in three years, so after hesitating, Chen Chu chose to bring them back.

Although this is a double-edged sword, with the combination of the virus, basic body-building exercises, and sufficient energy from heaven and earth, the strength of the Human Federation will be even more terrifying.

Moreover, practitioners are highly resistant to viruses. As long as the virus's ability to spread can be eliminated and its mutation function can be retained, it will be enough to further strengthen the physical fitness of those practitioners.

But at this moment, Chen Chu's eyes moved slightly. In his perception, the split virus in the air was getting less, and Xie Chen was also shocked.

"Not good, these viruses are being neutralized by the energy of heaven and earth."

boom!

The powerful sword intent shook the base, isolating the energy of heaven and earth and forming a vacuum with a diameter of ten meters, which enveloped and protected the viruses that were hundreds of times smaller than dust.

"This..." Looking at the more than 200 secret books floating in the air and the viruses that ordinary people cannot see or perceive, Chen Chu and Xie Chen, who had looked solemn just now, looked at each other. They did not expect this result.

Chen Chu was thoughtful: "No wonder when I tested myself, I felt that practitioners were very resistant to viruses. After all, these virus 'organisms' are afraid of the energy of heaven and earth."

In this way, the threat posed by these viruses is greatly reduced, and they need to be carefully protected. At the same time, they are also simpler to use. You can directly use a syringe that shields the energy of heaven and earth to absorb the viruses and inject them into the bodies of those low-level practitioners.

Xie Chen thought for a moment and said, "We still have to be cautious about this matter. I will do some research later. If the virus mutates and has antibodies to the energy of heaven and earth, it will be very troublesome."

"Well, I'll trouble you in this regard, senior." Chen Chu nodded.

The "death" of these doomsday viruses just now should be due to environmental reasons, which does not mean that these viruses are no longer a threat.

After handing the virus matter over to Xie Chen, Chen Chu directly connected the smart watch to the Tianyu Think Tank and uploaded the information about his self-created skills.

Half an hour later, Chen Chu came out from under the base alone, came to the silver vortex that was more than a thousand meters high, and went straight in.

Boom! Instantly the entire vortex shook violently, the powerful spatial fluctuations even caused the entire world to shake, the momentum was terrifying, as if a Titan beast had entered.

Such a powerful movement immediately startled the soldiers in the channel base, including the opposite side.

Li Daoyi was the closest to the channel, on the deck of the space-based warship with Expedition 13 printed on it, looking at the channel emitting circles of silver light. He was a little surprised: "Fuck, what's going on? The world channel is shaking so badly?"

Just as Li Daoyi finished speaking, he saw a figure with black hair and a shawl walking out of the passage in the center of the shocking silver vortex.

"day!"
