Not even a Dao Realm expert could shake the Heavenspan Mountain. A long time ago, a Dao Realm expert had tried, and the result proved that the Heavenspan Mountain was indeed unshakable.

Back then, there had been several earth-shattering battles in the Tong Tian Mountain, shattering thousands of kilometers of rivers and mountains. However, the main body of the Tong Tian Mountain had not suffered much damage. It had experienced countless tribulations and was immortal. This was astonishing.

Many people felt that it was very strange. How could a dead object like the Heavenspan Mountain be able to resist a Dao Realm expert? Why would he be able to remain immortal in a world-shocking battle?

One had to know that a Dao Realm expert was almost equivalent to a True Immortal in the sky. Moving mountains and filling seas, picking stars and catching moons was simply omnipotent, but in the end, they would actually fail in front of the Heavenspan Mountain.

In response to this question, many people put forward conjectures.

Some people said that this was because the Divine Mountain had spirits, and it had already given birth to a mountain god that belonged to him and could protect himself.

Others said that the Heaven Splitting Demon Emperor had set up a peerless array here to protect this ancient divine mountain.

There was even an even bolder rumor that the Tong Tian Mountain was actually formed from a tree trunk of the World Tree. With the World Tree trunk as the backbone of the mountain, it was covered with a thick layer of rock and mud, which was why it became such an ancient divine mountain.

Not to mention how absurd this rumor was, on the surface, Tongtian Mountain really looked like a tree trunk. The mountain was extremely steep, but the top of the mountain was abnormally flat. It was like a cylinder. Wasn’t it the shape of a tree trunk?

If the Heavenspan Mountain was really formed from the trunk of a World Tree, then it would be hard to imagine how enormous the World Tree’s true form was in ancient times.

“I don’t even know if the World Tree exists. This rumor is truly absurd.” Li Qing whispered.

It was not that the world did not believe this rumor. It was because the World Tree was too ancient. It was so ancient that no living creature had ever seen it, and it was almost impossible to prove its existence.

Legend has it that it was the first creature born between heaven and earth. Later, it died in response to the tribulation and turned into seven seeds. This was the origin of the Seven Divine Tree.

When the World Tree responded to the tribulation, not even the three great ancient Heavenly Yaos had been born.

One had to know that the three great Heavenly Demons were bred from the Demon Ancestor Tree. The Demon Ancestor Tree was one of the descendants of the World Tree. One could imagine how ancient the World Tree was.

There is no indication that the World Tree ever existed. Perhaps this is just a bold conjecture that will never be confirmed.

“Forget it, what am I thinking so much about?” Li Qing shook his head in boredom.

He strolled around and entered the Bodhi Academy. This was an extremely ancient courtyard. Back then, the Heaven Splitting Demon Emperor had once listened to the Dao here before embarking on the path of cultivation. It could be guessed that this courtyard should at least have been built in the last years of ancient times. It was simply a miracle that it could be preserved to this day.

There was nothing inside, let alone any treasures, even the plaque on the door had been removed.

Everything had been plundered, so it was impossible to hide any treasures. Since Li Qing knew this, he did not intentionally force himself to search for treasures.

It was covered in dust. When Li Qing entered, he felt an aura of decay. There was only an empty shell left here, and it could collapse at any time.

At the center of the Subhuti Academy was a large hall. It was not very spacious, and the decoration was very simple. It did not look shocking.

Li Qing entered the hall. As he had expected, nothing was left inside. To be exact, it wasn’t completely empty. The only thing that existed was a stone platform at the front of the hall.

He guessed that this stone platform should be used to place the ancestor’s tablet or statue. It was connected to the main hall and could not be moved.

The tablets and statues were all removed, leaving behind only this bare stone platform, which had endured countless years.

“Let’s have a rest here.” Li Qing sat down unhurriedly and felt a tranquil aura in the hall. After staying here for a long time, his entire body calmed down.

At this moment, he felt that something was moving inside his spatial ring.

“Eh? What’s the situation?”

Li Qing took out the strange thing and discovered that it was the stone egg. At this moment, it was actually tightly attached to a piece of wood.

This piece of wood was the heart of the Demon Ancestor Tree.

“This stone egg actually survived? How is that possible?” Li Qing’s eyes widened, feeling incredulous.

At this moment, the Demon Ancestor Tree’s heart lit up slightly. It emitted a mysterious power that was infused into the stone egg. The life aura inside the stone egg actually increased slightly.

“I’m really alive! Although I only managed to increase my life aura by a bit, if this continues, I’ll be able to save this stone egg sooner or later.” Li Qing couldn’t help but sigh at the miraculousness of creation.

The ancient stone egg had almost turned into a fossil, yet it could be revived? If they hadn’t seen it with their own eyes, no one would have believed it.

Under normal circumstances, this stone egg was indeed hopeless. Although there was still a trace of life force left behind, it was not enough to revive it.

However, he didn’t expect that with the help of the Demon Ancestor Tree Heart, the Stone Egg would miraculously come back to life. This was the miracle of good fortune. Nothing is impossible!

This tree heart was truly extraordinary! It actually had such an effect.

The Demon Ancestor Tree was a very mysterious ancient tree. Even the three great ancient Heavenly Yaos were bred by it. One could imagine how powerful its effects on demonic beasts were. Now that its tree heart had rescued a demonic beast’s egg, it didn’t seem to be that difficult to accept.

“This stone egg is obviously an extremely ancient creature. I wonder what kind it is. Should I save it?” Li Qing hesitated.

As the saying goes, non-humans have different hearts. This stone egg was a mysterious demonic beast. It was hard to say if it would rebel after becoming powerful. If he helped the demonic beast’s power, then he would become a sinner.

“Forget it. Save it and observe it carefully for a while. If this demonic beast makes people feel danger, then strangle it in the cradle.” Li Qing made up his mind.

Looking at the stone egg tightly stuck to the Demon Ancestor Tree’s heart, Li Qing was about to put the two items back into his spatial ring when another mutation occurred.

The Demon Ancestor Tree’s heart had actually escaped its control. Its brilliance blossomed and floated in mid-air. It was beating like a heart, as if it could faintly sense some mysterious creature underground.

Then, a ray of light sprayed out from the tree core and shone on the stone platform. The stone platform actually split into two halves, revealing a dark passageway.

“What is this situation?” Li Qing was shocked. He guessed in his heart, “Could this be some kind of lucky chance? Was it opened by the Demon Ancestor Tree Heart by a coincidence of karma?”

This ancient courtyard has been abandoned for so long, so there shouldn’t be too much danger. Li Qing couldn’t help but feel curious and decided to enter the passageway to see what was going on.

He put the Demon Ancestor Tree Heart and the Stone Egg into his spatial ring and entered the pitch-black passageway.

The stone platform was closed and the passageway was closed. The place had regained its calm. No one was alarmed. No one knew what had happened here.

Li Qing released his divine sense and carefully advanced along the passage.

The passageway was very long, and it was slanted downwards. It should have gone deeper underground.

After walking for half a day, Li Qing felt that the pressure in front of him was getting stronger and stronger. This kind of pressure was not to suppress people, but to push them out.

Li Qing withstood this pressure and relied on his own brute force to forcibly advance.

Not long after, he encountered a light green light barrier in front of him. There was a faint pressure emanating from this light shield, causing people to be unable to help but worship, as if they were paying their respects to their ancestors.

“What a miraculous light shield! How do I get through this?”

Li Qing was very cautious. He threw a stone over from afar and was bounced away by the light barrier. There was no other abnormal situation.

There shouldn’t seem to be any danger.

Since he didn’t know the method to open the light shield, he didn’t want to waste any time and planned to directly use brute force to blow it away.

Li Qing punched out and hit the light barrier. His body trembled and he was counterattacked by a huge force. Then, he flew backwards.

The light shield was like a calm lake, without the slightest fluctuation, as if the punch just now had no effect on it at all.

“What a terrifying light shield! There isn’t even the slightest fluctuation! The difference is too great!” Although Li Qing wasn’t injured, he knew that there was nothing he could do about it with his own strength.

Could it be a light shield set up by a Dao Realm expert? Otherwise, how could he be so powerful!

Since he had arrived here, it was naturally impossible for him to give up halfway and return empty-handed when he encountered a treasure mountain. He had to find a way to open the light shield, otherwise he wouldn’t be able to pass through.

“Do you want to split it with a Heavenly Saber?” Li Qing pondered for a while before his mind suddenly flashed.

“Oh right, Demon Ancestor Tree Heart! How did I forget this thing?”

He hurriedly took out the tree core and spat out a ray of light, illuminating the light barrier. Something pleasantly surprising happened to him, and the light barrier immediately melted, forming a portal for one person to enter and exit.

Li Qing entered through this door, and the light barrier quickly healed again.

Li Qing continued to walk forward, holding the Demon Ancestor Tree Heart in his hand. The pressure in front of him had actually disappeared. This tree heart was like a passport to this place, allowing people to unobstruct it.

He didn’t know what the connection between the tree core and this ancient cave was. Not only could it open the light shield, it could also relieve the pressure.

He could feel that the tree heart was trembling slightly, and it could even be said that it was a little excited. Even if he couldn’t understand Tree Heart’s emotions, he could still feel a sense of wandering children returning home.

A second light barrier appeared in front of him. Li Qing used the tree core to open a door and enter.

Unobstructed!

On his next journey, Li Qing encountered seven layers of green light shields. They were all opened by the tree core before he could enter.

“This defense is really tight! I wonder what kind of precious things are inside!” Li Qing’s heart was filled with anticipation.
