Inside the room.

The broken wood block in Yang Tian's hand emitted a strong light.

Yet this light was very gentle.

"Could this really be a treasure?"

Yang Tian used his Divine Sense to probe into the broken wood block and felt a vast Spiritual Breath.

This Spiritual Breath was like an ocean.

Originally, this broken wood block was placed in the Sand Demon Treasure Vault, without any Spirit Breath Wave.

Even the Sand Demon King thought it was trash.

But when the holy Sword Qi inside Yang Tian flowed into the broken wood block, a hidden oceanic breath inside the block emerged.

"Such a vast Spiritual Breath, my Dantian's Spiritual Breath is probably only one ten-thousandth of it!"

Yang Tian was extremely surprised.

One must know, for a cultivator, the most important part is the Spiritual Breath in the Dantian.

The higher the level of the cultivator, the larger the Dantian, and the more immense the Spiritual Breath inside.

But Yang Tian had never seen such an immense Spiritual Breath.

In his experience, the most terrifying existence was the Witch in the Dark Land.

But even the Witch's Spiritual Breath wasn't as immense.

Yang Tian ran his Divine Sense to explore, lying as if a lone boat in a vast ocean of Spiritual Breath inside the broken wood block.

"Wrong! This vast Spiritual Breath is probably a hundred thousand times mine!"

Yang Tian exclaimed firmly.

Then, he was filled with doubts.

What is the situation of such a vast ocean of Spiritual Breath?

Whoosh!

A ray of light suddenly shot out from the broken wood block and entered Yang Tian's mind.

At that moment, Yang Tian froze.

In his mind, an Ancient Tree suddenly appeared.

This tree stood between heaven and earth, towering into the clouds, its top unseen, its roots buried in the ground, as large as half of Huaxia.

The roots, branches, and leaves were so large that Yang Tian was shocked.

Probably the big locust tree in the valley was just a knot of this Ancient Tree.

Such a massive Ancient Tree emitted no birds or beasts, eerily quiet.

But the blue glow from the Ancient Tree told Yang Tian that it was definitely a Treasure Tree.

Whoosh!

Another booming sound rang out.

A second ray of light shot out from the broken wood block and entered Yang Tian's mind.

Quickly, in Yang Tian's mind, emerged scenes intricately connected to the Ancient Tree.

A long time ago, the Demon Realm did not exist; it was a void.

But after an unknown duration, a small tree grew in the void, crazily absorbing its surroundings, growing wildly.

Within years, the small tree grew to be as big as half of Huaxia, becoming an Ancient Tree.

And upon the tree, fruits sprouted from branches.

Inside these fruits, there were demons.

There were Celestial Demons, Sand Demons, Blood Demons, Corpse Demons.

When the fruits were about to mature, the Ancient Tree dispersed, turning to soil, quickly forming a Demon Realm.

And the fallen fruits gave rise to Celestial Demons, Sand Demons, Blood Demons, and Corpse Demons.

These demon races survived and developed in the Demon Realm, gradually forming a notorious Demon Realm.

Yet these demons knew nothing of the Ancient Tree.

After self-destroying, the Ancient Tree left behind a small twig, the broken wood block in Yang Tian's hand.

"Who would have thought that this small broken wood block is the life source of the Demon Realm!"

Yang Tian couldn't help but exclaim.

Yet, he was puzzled, now that he obtained the broken wood block, what use was it?

Whoosh!

Almost the next second, another light shot into Yang Tian's mind.

This time, what appeared in Yang Tian's mind was still the Ancient Tree, but its spirit had already integrated with Yang Tian's soul.

Yang Tian seemed to become the Ancient Tree.

He could feel the Ancient Tree crazily absorbing the void, turning it into a vast Spiritual Breath.

On the Ancient Tree, magic buds sprouted.

Inside these magic buds, there were Magical Treasures, Celestial Demons, Sand Demons, Blood Demons, Corpse Demons, and some unknown creatures and materials.

All these magic buds were crazily absorbing the Spiritual Breath transformed by the Ancient Tree.

Soon, the Magical Treasures formed, and Celestial Demons, Sand Demons, Blood Demons, and Corpse Demons were produced correspondingly.

Moreover, the most surprising to Yang Tian was a small grain of sand entered a magic bud, absorbing the vast Spiritual Breath, actually growing into a piece of gold.

Not only that, a piece of broken iron absorbed the Spiritual Breath, turning into a superior Demon Sword.

Reading this, Yang Tian excitedly said, "Could it be that this Ancient Tree can bring me endless treasures and demons?"

If that's truly the case, Yang Tian would be unstoppable.

This equates to him owning a treasure vault capable of producing treasures and demons.

Afterwards, he just needs to put in a grain of sand to produce a piece of gold.

Just needs to put in a piece of broken iron to produce a Demon Sword.

Just needs to put in a demonic thought to produce a demon.

Whoosh!

Three lights dispersed, Yang Tian's Divine Sense returned to his body.

The broken wood block in his hand continued to emit a gentle blue glow, but Yang Tian's heart was filled with immense joy.

"This Demon Wood could be a terrible existence, it's just not clear if the treasures and demons produced by it will answer to me?"

Yang Tian questioned with doubt.

He directed his Divine Sense into the Demon Wood and saw a piece of gold inside, with just a thought in his hand.

Whoosh!

The next second, a piece of gold appeared in Yang Tian's palm.

"This gold..."

Yang Tian was excited.

He only needed a thought with his Divine Sense to retrieve items from the Demon Wood.

In the future, wouldn't he be able to use this Demon Wood to produce endless treasures and demons?

"Now the most important thing is to plant this Demon Wood and let it grow into the Ancient Tree!"

Yang Tian said, then flew out of the Demon Mansion.

No one knows how long he flew, Yang Tian reached the depths of the Demon Realm Forest and planted the broken wood block in the ground.

Soon, the broken wood block started growing at a visible speed.

In no time, it grew into a small tree as tall as a person.

"At this rate, it will soon become an Ancient Tree!"

Yang Tian said excitedly.

But he also worried that once the broken wood block became an Ancient Tree, wouldn't it attract the attention of the many demons?

Almost the next second, the broken wood block disappeared.

"Did it turn invisible?"

Yang Tian reached out to touch but couldn't feel the existence of the small tree.

He ran his Divine Sense again, and the small tree reappeared.

This way, Yang Tian understood that he could use his Divine Sense to make the broken wood block invisible and visible.

"Let it grow here and become the Heaven-Reaching Demon Tree, then I can produce treasures and demons!"

Yang Tian's emotions were hard to contain.

He stayed in the forest until dawn, then flew back.

Along the way, he kept thinking, once he returns to Huaxia, uses his Divine Sense, he can take treasures and demons from the Demon Realm, how thrilling!

"Soul Summoning!"

As soon as he landed in the backyard of the Demon Mansion, Yang Tian heard a familiar voice.

He used his Divine Sense and saw a graceful figure in the backyard.

It was none other than Wu Zetian.

Soon, Yang Tian clearly saw that Wu Zetian was using the Soul-Calling Banner for soul summoning.

Whose soul was she summoning?

Summoning the master's soul?

Yang Tian hurriedly approached...
