The question of where exactly the Optimus Tree came from is already clear, the ruins of the gods from the main galaxy.

This is a twin galaxy, hundreds of thousands of years, or even millions of years ago, at the same time as the destruction of the main galaxy world, the sub-galaxy world ushered in the era of flood, and the demon race appeared.

Qin Xuan looked at the land under his feet, the history of this world is also very long, hundreds of thousands of years of vicissitudes, there are countless dusty histories and mysteries, there is no doubt that this labyrinth of ruins from the ancient demon clan era is likely to have another Nirvana Divine Tree.

The Qi of Otogi in the labyrinth comes from this Nirvana Divine Tree.

Perhaps, the Divine Tree had withered long before the Demon Continent was shattered, but the remnants of the wood it left behind still had the effect of transforming the qi of heaven and earth into the qi of Yimu.

The puzzle is solved.

Qin Xuan looked up at the top of the labyrinth, his spiritual sense expanded, and he sensed all the plants and trees here, and knew in his heart that this labyrinth was the root of a Nirvana Divine Tree, and all the tunnels here were once the roots of every tree, and the root system was infinite, spreading to the endless depths of the ground.

Hundreds of thousands of years ago, or 100,000 years ago, it was a real Optimus Tree, and the canopy covered the entire Demon Continent, and the central part of the root of the tree alone was a hundred miles in radius.

In front of Qin Xuan's eyes, a small Optimus Tree that had been extinguished quickly revived and ushered in a new life.

Qin Xuan held the Heavenly Ruler in his hand and communicated with its soul thoughts, but the result did not exceed Qin Xuan's expectations, this was the divine power of Nirvana rebirth, similar to reincarnation, and there was no trace in the divine soul.

Although this revival little optimus tree is ten feet tall and has a knotted trunk, it is actually no different from a newborn sapling.

Qin Xuan's spiritual sense followed the roots of this tree, all the way deep into the ground, and quickly discovered a new world, the entire labyrinth was the roots of the divine tree, the central part was a hundred miles square, but there were dozens of tree roots spreading to the ground, heading in all directions.

Although the sacred tree is dead, its roots are still generating new Otogi energy.

The moonlight floats, wisps like silk.

Qin Xuan's figure flickered, casting the void spirit of yin and void, his body was between the void and the real, strolling at the bottom of the tree roots, which was equivalent to the second underground layer of the labyrinth, and there was rich Yimu spiritual liquid everywhere, green elite, like condensation.

Thirty-three huge tree roots, each several miles in diameter and more than a hundred miles long, extend to the depth of 10,000 zhang under the island of Tengzhou, and most of them have penetrated to the deeper part of this giant star, the legendary Yuan Magnetic Realm.

"So that's the case!" Qin Xuan figured out a few other things, first of all, the Yuan Magnetic Spiritual Essence of the Eastern Branch Qi Family came from the second underground layer of the labyrinth, and if you walked along the deepest and central roots, you would definitely be able to find the Yuan Magnetic Spiritual Essence.

Secondly, the reason why the Qi family wanted to split the western branch was because they found another entrance and sent a part of the ethnic group to guard it and steal the benefits.

Therefore, all the things that Qi Changye said two days ago were farts.

With the current strength of this Long Night Ancestor, as long as this Ancestor is willing to lie dormant in the roots of the tree and practice, it will not be difficult to prolong his life for more than two hundred years, and he will even have the opportunity to enlighten the Pure Yang Ancestor.

Each tree root is a huge tunnel in the labyrinth, several miles in diameter, shaped like a huge cave boundary, hundreds of miles long, dozens of miles deep, and the end is filled with a terrifying atmosphere.

Obviously, there are many terrifying demon beasts lurking in the deepest part of the labyrinth, and their bloodline aura is extremely ancient and mysterious, most of which originate from the desolate alien species.

Qin Xuan slowly explored all the way along the tunnel in front of him, holding the Sumeru Pagoda in his hand, collecting the Yimu Spiritual Liquid here.

But all secret realms are isolated from the world after all, and there are restrictions after all.

This is like a yin and yang island with a slightly smaller ban, Qin Xuan is not worried that there will be demon beasts in the Law Phase Realm, but they are all descendants of the Flood Desolation Alien Species, such as Spirit Pix, Hook Snake and the like, and their strength is definitely not lost to the Law Phase Realm, and there are many of them.

According to the rules of the Maze in Tengzhou, anyone can only collect three small divine products in the maze, or a divine spirit grass, and can only subdue one demon beast at most.

Otherwise, they will inevitably be teleported away by the labyrinth's large array.

Qin Xuan walked forward slowly, and finally encountered the first demon beast, shaped like a giant ape, with a pale and hard body, covered with white hair, and a golden heavenly eye in the center of his eyebrows.

Roar.

An angry roar.

Qin Xuan's spiritual sense swept over, as if he had raised his hand to brush the boundary around the golden-eyed giant ape, and he could easily detect several divine spirit grasses, and on the walls of the trees that had already been petrified, drops of green spiritual essence were condensed.

Otogi Spiritual Essence.

This is a heaven-level spiritual object of the same level as the Yuan Magnetic Spiritual Marrow, and it is said that refining this thing can not only enhance the cultivator's wood-based spirituality, but also greatly increase the longevity.

The giant ape grabbed the air with one hand and ingested it in the air, which turned out to be a spatial supernatural power, restricting Qin Xuan, who was about to evacuate.

Qin Xuan had no choice but to fight with it.

The ancient god who arranged the Maze in Tengzhou back then was very thoughtful, and left a large number of maze tokens, matching with the big array, and only by holding the token can he enter the hole, but as long as he holds the token, he will inevitably be bound by various rules in the big array.

It's not forbidden to hunt monsters here, and the rule is that you can only kill a maximum of three, provided you can beat them.

What's more, the demon beasts here are all at the pinnacle of the demon pill realm, and their spiritual intelligence is extremely high, if you dare to kill, you will inevitably usher in a wheel war.

Just in case, Qin Xuan set up the formation first.

The ghost bamboo cane and the Liuyi Banner flew out at the same time, turning into a Heaven and Earth Liuyi Array, allowing the giant ape to break in and suppress it again.

"Boom. The giant ape laughed evilly, his golden eyes opened, and he quickly found Qin Xuan hiding in the void, his arms were like fishing for the moon, facing the void and grasping the void, the strong and domineering mana could directly penetrate the void and restrain Qin Xuan again, and it was tearing the void, tearing Qin Xuan into pieces along with the space.

"Boring, find your own death!" Qin Xuan sneered, stepped on his foot, and there was an extra hundred-zhang demon jiao.

The spirit cranes and turtles around him are not good at fighting, and they are more suitable for swimming in the sky and water, and they are used for transportation, and the magic Jiao is different.

After refining the demon spirit left by a certain True Jiao ancestor, the Baizhang Great Snake ascended to the sky in one step, reversed the innate destiny, and turned into a demon Jiao, which is the supreme bloodline in this heaven and earth.

What's more, the Qinghai King Snake was originally good at the magic power of the space line.

The Demon Jiao's four claws fluttered, and quickly cracked the giant ape's spatial supernatural powers, and his figure flashed, exerting his spatial supernatural powers, escaping to the giant ape's side, wrapping around it, and grabbing its limbs with four claws.

The strength of these two was originally about the same.

The giant ape's cultivation is even more profound, and it is already the peak of the demon pill realm, if it were not for the restriction of the secret realm, it should have been enlightened a long time ago.

Qin Xuan's Baizhang Demon Jiao cultivation is slightly inferior by one level, and it is better than a higher and stronger bloodline level, and it is still the real number one in the world, firmly suppressing the golden-eyed giant ape.

Between the two sides fighting.

Qin Xuan has borrowed the mana of Yin Void to arrange this Heaven and Earth Liuhe Array perfectly, he let Yin Void merge into his own Yin Soul Incarnation, although he has taken a lot of risks, and he will have to cross the tribulation together in the future, but there are too many benefits at present, and the mana he borrowed is even more like a finger, and he can do whatever he wants.

The Heaven and Earth Six Array is one of the three major killing moves of Yin Void, and the other two moves are the Void Spirit Hidden Divine Escape and the Ten Purple Qi Beast Talismans.

As soon as this array came out, the heavens and the earth were closed.

In the labyrinth secret realm, create a new secret realm of a thousand feet.

"Demon, if you don't descend now, when will you wait?" Qin Xuan took out the Ruyi flute, and was about to play the Soul Devouring Demon Sound, this move cooperated with the Heaven and Earth Liuhe Array, the effect was excellent, and even the Qi Changyou Ancestor was killed by him, and life was better than death.

"Boom!" the giant ape monster laughed, and with a sudden shock, it turned into a puff of white hair, scattered on the ground, and it was actually just a doppelganger supernatural power.

Roar.

Outside the Heaven and Earth Six Array, there was a long roar of the giant ape, and the tone changed suddenly, as if it was calling for other allies, and soon, there were bursts of roars of the giant ape echoing it in the distance.

Dizzy.

It turned out to be a group of giant ape demon clans.

Qin Xuan finally understood that although the Eastern Branch Qi family knew the source of treasures such as the Yuan Magnetic Spirit Essence, it might not be easy to get a few copies, every tree root here, in the hundred-mile-long tree root cave realm, I am afraid that there is a demon clan guarding the descendants of the desolate alien species.
