After four years of cultivation in the Giant Wood Academy, it was the first time that Qin Xuan was so close to the Optimus Tree, this tree itself had the blessing of a large array, and Qin Xuan's True Inheritance Waist Card was the magic weapon for entering the secret realm in the tree.

Of course, not all true disciples of the Star Sect can enter, only the Giant Wood Courtyard Master can do it.

The array gate opened, revealing a tree hole passage, like a wide city gate more than ten zhang deep, and in front of it was a deep and abyss-like secret realm, with a hundred zhang high above and a hundred zhang deep below.

Qin Xuan rode the slow-flying wooden crane puppet, controlled it with spiritual power, flew up in the secret realm, and slowly saw the twenty-eight tree holes scattered in various corners above, just to build a star array.

He continued downward, deep into the bottom of the secret realm.

Located deep in the roots of the Optimus Tree, there are only five larger caves, each with a wordless plaque above the door, and a long-abandoned teleportation array in the middle of the five caves.

Qin Xuan took out the Seven Star Hundred Bird Bell, held the bell rod and shook it gently, his sound cultivation was insufficient, and he temporarily used it as an ordinary Seven Star Bell, stimulating more levels of sound waves.

In the secret realm of the sky, the sound of the bell is crisp, and the large array floats out layers of ripples, full of colors, revealing a small world-like array space, the underground five elements flow, and the twenty-eight heavens are brilliant.

This is the realm in the tree, the array of Zhou Tian, headed by the wooden cave in the Five Elements Cave Mansion.

There are layers of forest strictly forbidden around the wooden cave, which is completely different from other caves.

Qin Xuan's spiritual sense spread with the sound of the bell, and the specialty of the medicine spirit was revealed, perceiving the subtlety of the entire secret realm, and the result made him a little surprised, although the Optimus Tree had a sense of old age and extinction, it was by no means thousands of years ago, but it was only in the past hundred years that the real aura of silence was revealed.

It's no wonder it's going to last for thousands of years.

In Qin Xuan's heart palace, the extremely mysterious Jin Luan suddenly appeared, flapping its wings, as if it was about to fly towards the Mudong Mansion, and there was a strong desire, as if that was its final destination.

It left from the secret cave of the Feiling Cave Heaven and stayed in Qin Xuan's heart palace, silently waiting for this moment.

Qin Xuan's heart moved, and he concluded that this was the real opportunity, and walked to the thick wooden door of the Wooden Cave Mansion in one step, and pressed it with his True Inheritance Waist Card, the prohibition around the Cave Mansion was set by the predecessors of the Giant Wood First Vein of the Xingchen Sect, and the Dao Law Seal was superimposed on the True Inheritance Waist Plate, making him the new owner of this Cave Mansion.

After a few moments, he controlled the prohibitions, only to find that there was an even more powerful inner layer of prohibitions on the wooden door, shaped like pale green amber several feet thick.

He was about to find a way to break this somewhat strange inner prohibition, Jin Luan let out a long roar in his heart palace, melodious and high, like the sound of the gods, endless majesty, the pale green amber actually opened up, and the green fat flowed into his true inheritance waist card, turning into a shadow of the Optimus Tree.

Crunch.

The heavy wooden door of the wooden cave house is finally opened, and the wordless plaque above the door of the house emerges a layer of five-color magic light, and the three characters of "Panmu Cave" are conjured, which is like a snake swimming, and it is the small snake seal body that was common in ancient times.

There is no cave in the cave, a hundred zhang square, the top is a clear and clear sky, the whole cave is like a deep well in the world.

This is obviously an extremely superb formation technique, which skillfully grafts the formation space in the cave and the large space of the outer heaven and earth into one, which is a step higher than the common formation path skylight technique.

This kind of attainment is probably already at the level of a Formation Dao Grandmaster above the Nine Ranks, and it is impossible to do it without the likes of the Divine Ancestor.

Qin Xuan sighed for a while, daunted, and didn't know when he would be able to reach this level.

The spiritual soil in the Panmu Cave is thick, hundreds of spiritual grasses grow here, all of them are longevity grasses such as Shouwu Salvia, there are also hundreds of Ganoderma lucidum trees growing on the wooden wall of the Cave, and the center is a small optimus tree ten zhang high, the main body is straight, and the ten thousand branches are twisted and coiled.

Qin Xuan's medicinal spirit specialty had many wonderful uses, and he only needed his spiritual sense to cover the surroundings, and he could sense that all the essence of the spiritual grass and Lingzhi in this place was pouring towards the Little Heavenly Tree, maintaining its survival.

This small optimus tree seems to be no more than ten zhang tall, and the branches and leaves cover it only ten zhang of land, but in fact, the tree is old, at least 3,000 years old, and it is very special.

Qin Xuan walked under the tree and sat down, running the exercises, fully exerting his medicinal spirit expertise, and communicating with all the spiritual herbs and lingzhi in this small supernatural tree and the surrounding hundreds of zhang land.

At this moment, Jin Luan, who was deep in his heart palace, spread its wings, and was also sensing this cave, it had its own consciousness, searching for something.

Many sounds of plants and trees poured into Qin Xuan's heart, and one of the voices was extremely solemn and thick, and he couldn't wait.

"Fei Ling, are you not false?"

"Who is the senior?" Qin Xuan asked silently, he vaguely guessed that this was the voice of the sky, and it was only transmitted to him through the little Optimus Tree.

"How fortunate it is...... Truly thou!"

Qin Xuan didn't understand what the other party meant, and immediately understood that the voice of the sky was talking to Jin Luan in his heart palace, but he couldn't hear the voice of Jin Luan.

"Fortunately, it's really you, my generation has endured humiliation for 4,600 years, and it is enough to see that Zhou Tian has not been extinguished. My Shouyuan has been exhausted by the Bodhisattva, and I regret that I can't go with you. ”

The voice of the sky became more and more hoarse and excited, and an invisible giant palm shrouded down, covering Qin Xuan and transmitting countless memories.

Qin Xuan seemed to be suddenly in the dark and deep starry sky, turning into a scorched black relic and drifting in the Infinite Universe, constantly absorbing star power and speeding towards a huge blue planet.

It was a strange giant star, quiet and beautiful, the sea was blue and endless, in the middle of the ocean was a huge land, but the back of the planet was shattered, as if it had been hit by a giant meteor, the magma was like a sea, and the black fog was filled, it was like hell.

The giant star is surrounded by a vast ring of stars, drifting with tens of billions of starfalls, ranging in size.

After 10,000 years, a god-like Ancient Venerable finally walked out of the giant star, walked through the star ring, found the relic, and learned the infinite Dao method from it, and brought it back to the giant star.

Thousands of years later, the Ancient Venerable stepped on a galaxy and flew away from this world, and his disciples and descendants carefully preserved the scorched black relics, opened a sect in the place where the Venerable practiced in the past, called Zhou Tianzong, and continued to comprehend the infinite Taoism in the relics from generation to generation.

Ten thousand years of prosperity, ten thousand years of dying.

Twenty-three thousand years later, Zhou Tianzong finally sensed the signs of the catastrophe of destroying the sect, and a group of Zhou Tianzong monks followed the order of the master, quietly left with the charred black relics, and traveled all the way west to the West Sea.

Here they found a huge island and hid the remains underground.

The wood gas in the relics gushed out, so that a spirit tree awakened into a spirit demon, and it rose from the ground in more than 100 years, towering and majestic, and was called Qingtian.

After another hundred years, Zhou Tianzong finally fell, and another group of monks from Zhou Tian's lineage arrived here, and the two sides quarreled, and the group finally left, and only one of the leaders had the opportunity to enter the secret realm of Superheaven and see the true body of the dryad here.

He told the Dryad Sect that he was not dead, but that the weather was running out for a week, and he needed to parasitize his faction to accumulate luck and wait for a real catastrophe to come.

This leader's name was Zhou Feiling, and his sister was none other than the Zhou Tian Sect Sect Feixia Ancestor, who were the last two direct descendants of the Ancient Venerable.

After 1,700 years, the Optimus Gate was destroyed, and another Bodhi Dryad arrived here, defeated the Optimus Tree Demon, and told him that the Qi of the Star Sect and the Zhou Tianzong had been exhausted, and the future was the era of the Star Sect.

The Bodhi Dryad trapped the Optimus Dryad in the formation, and finally, more than a thousand years later, began to draw on its vitality.

Time flies, and three thousand years pass in a hurry.

The longevity of the Optimus Tree Demon was exhausted, and only the last wisp of vitality remained in the Wood Cave Mansion.

"It, its real name is the Nirvana Divine Tree, and the Phoenix Tree is also. At the end of the memory, the voice of the sky was endlessly sad, and it seemed to see a ray of hope.

In the cave, the little Optimus Tree suddenly disintegrated and collapsed into countless stumps and broken leaves, broken branches and broken branches, and finally turned into layers of dark green dust, dissipating in the entire cave, and the last vitality was all fed back to those spiritual grass Lingzhi.

"Thank you, fellow Daoists. ”

This was the last bit of the sound of the sky, full of gratitude and guilt echoed in the cave, and all the spiritual herbs and lingzhi were sad for it, even if there was a huge amount of vitality returned to their bodies, they were also so depressed and painful.

In the whole cave, all the voices were crying and screaming, as if it was raining.

Only a piece of charred black remains floated in the cave, silently falling into Qin Xuan's palm, nothing peculiar, like a burning stick.
