This line of footprints stepped into the depths of the ruins, and through these footprints, it seemed that a figure in a dragon robe stepped step by step in this ruin before the eons of time.

At this time, Xu Fu seemed to have found something in the ruins.

It was a golden drawing, held tightly in the hand of a decaying corpse.

This corpse has a very terrifying aura, and it is definitely not weak before it was born.

Xu Fu stretched out his hand to reach for the drawing, and was about to touch it.

A thick wisp of dark power was like a cold poisonous snake, suddenly turning out of the corpse, and instantly wrapped around Xu Fu.

His complexion changed drastically, and his body exploded with a brilliant light, intending to resist the black qi.

However, the terrifying nature of the dark power that corrodes and infects everything, even the Extreme Realm can be hit.

Xu Fu couldn't stop it at all.

Yun Chen flicked his fingers, and a sword light tore through the wisp of black qi.

A terrible scream came out, and this wisp of black qi seemed to have life, like a severed poisonous snake, falling to the ground and struggling and writhing.

Such a strange scene made Xu Fu feel cold all over his body, what would happen if he was really touched by this wisp of black qi just now.

He stared at the ruins, at the corpses, at the corpses, at the untold corpses!

It's that these corpses have this weird thing in them.

Xu Fu hurriedly bowed to Yun Chen: "Thank you for saving me!"

Yun Chen bowed slightly, reaching out to pick up the golden page.

On the page, there is a strange giant beast with a dragon's head and black scales.

It's not just a painting, it's ...... Drawings of artificially manufactured biological weapons.

It's like the Demon God Soldier of the Dao Alliance, like an alien, and other artificial creatures.

This drawing details the process of manufacturing a powerful biological weapon.

According to the information above, this is a man-made weapon called 'Dragon Eater', and even the lowest-level 'Dragon Eater' has Heaven Realm-level power.

This kind of creature does not swallow anything, if it is strong enough to be able to devour a thousand worlds, or a thousand worlds, this kind of thing can even be comparable to the extreme realm, and can enter the great chaos to survive.

Even Yun Chen couldn't help but be surprised.

Looking out over this vast ruin, here ...... It's really a god and demon manufacturing factory.

Extreme Realm Gods and Demons can be created!

This base exists for the purpose of researching and manufacturing various biological weapons.

Many years ago, a powerful civilization sealed the entire world system as a testing ground and created the Abyss, building these laboratories in the core of the Abyss.

Capture the gods and demons of the Polar Realm as experimental objects, and artificially create an existence comparable to the Polar Realm.

Such a vast project, such an astonishing handiwork, what a powerful civilization should be able to do, this is the terror of the heaven-level forces.

What happened here? The entire base was destroyed and abandoned.

Is the mysterious civilization that created it all gone, or is it hidden somewhere, peeking into everything here?

Yun Chen looked up at the gray sky.

The heavens and all the worlds must be prosperous and brilliant, and they must be coexisted by all kinds of civilizations and all kinds of powerful people.

There are powerful monks who crisscross the worlds, and there should also be god-level civilizations that transcend the universe and dimensions.

The seal of this world system is a blessing and a curse, the seal prevents the strong who have reached the extreme from leaving this world system, and also prevents the danger of the outside world.

Yun Chen's vast divine sense swept out, searching for this ruin, and from the ruins, he found a full nine intact drawings one after another.

Each drawing records how a biological weapon was made.

The civilization that created the abyss has mastered the technology of mass production of gods and demons!

"This, how can it be ......"

Xu Fu also understood the meaning of this testing ground, and muttered in disbelief.

"Beyond time and fate, how can such a realm be artificially created?"

"How many living beings pursue the realm of infinite years, how can it be artificially created!"

Xu Fu's eyes were a little scattered, he had forgotten how many years he had practiced.

From the previous era, how many years he had experienced, but he had never been able to break through the last hurdle, and he was trapped in the Heavenly Realm Nine Layers for countless years.

Seeing that the soul is decaying, and the longevity is exhausted.

However, such a great realm, such a lofty realm, can be made by people!

Xu Fu's Dao heart was trembling.

He's worked so hard to practice all his life, but he's not even as good as a test in this laboratory?

"Detachment! detachment! cough cough cough!!"

"I've been cultivating for hundreds of millions of years, what is it that I cultivate!"

Xu Fu coughed a few times and spat out a mouthful of blood.

But at this time, Yun Chen frowned.

Look to the rear.

A voice came: "If it weren't for being trapped in the cage, Da Luo was hopeful." ”

The ethereal sound of vicissitudes seemed to come from outside the sky.

A purple gas appeared on the gray sky, and the purple qi spread out, stretching for 30,000 miles, and an old man fell in the vast purple air.

"The detachment in your mouth is not difficult to say, but easy to say. ”

The old man came from the sky, and his body was wrapped with Dao Dao divine light, as well as an ethereal and ethereal Dao essence.

Its breath is lofty, noble, this dignity is not the emperor, not the supreme, but as vast as heaven and earth, as high as heaven and earth, overlooking all things in the world, sitting and watching the vicissitudes of life.

Its gods are like heaven!

Yun Chen's eyes condensed slightly, Dao Ting, the purple-robed Taoist who looked at him before.

At this time, the Taoist looked over and saluted Yunchen: "My name is Hong." ”

When Yun Chen heard the name, his brows furrowed, and he stared at the old man for a moment.

Suddenly, he said, "Hongjun?"

The old man glanced at Yun Chen with deep meaning, and said again: "I am Hong!"

Yun Chen raised his eyebrows, the old man in front of him must have a relationship with Hongjun, either as an incarnation, or as he or me, but he should have an independent will, and not be controlled by Hongjun's true self.

Interesting.

But Xu Fu couldn't help but ask: "The predecessors just said that detachment is easy to obtain?"

Hong smiled and said in a long voice.

"The essence of detachment is to condense the Dao Dao Fruit. ”

"Whether it's practicing on your own or with the help of external objects. ”

"The Three Thousand Origin Dao evolves into an infinite world and differentiates into billions of laws, however, all changes are inseparable from their origins, and if you want to transcend, you need to break the law and point directly to the origin and perceive the origin of the Great Chaos. ”

"You can choose to cultivate on your own and condense your own Dao Fruit to become one, or you can choose to merge with the Origin Dao, or place your trust on external objects and use external forces to merge the Dao. ”

casually pointed Xu Fu with two sentences, and Hong didn't care.

Blink his eyes to look at Yun Chen: "Take the body of the killing, take its origin to achieve itself, and make a friendly means! No wonder you can break the shackles of this cage." ”

Yun Chen smiled, but did not talk to him: "I have a lot of doubts in my heart. ”

Hong was silent for a moment, and then stepped into the depths of the ruins, "Come with me!"

Yun Chen did not hesitate and also took a step.
