Whether or not they are ancestors has nothing to do with him; he was just doing it as a favor to Zhan Tian.

Zhan Tian nodded in satisfaction, then infused nine streams of spiritual power into the stone pillars.

Suddenly, the entire room dimmed, and one by one, points of light appeared in midair.

Familiar numbers and unfamiliar names.

"So many!"

Chen Xuan looked at the flickering numbers, there were at least dozens.

"Alas!"

At this moment, Zhan Tian sighed, "More and more lower realms are being obliterated."

But at this time, Chen Xuan, how could he care about him?

"Boom!"

Streams of spiritual power emerged, sensing these dozens of flickering points of light.

"No..."

"No...."

...

Afraid of making a mistake in sensing, he checked each one several times.

Zhan Tian, standing to the side, looked at him suspiciously; he was looking for an obliterated lower realm.

"Could it be that someone around him came from a lower realm?"

He speculated in his heart.

"Impossible!"

Chen Xuan exclaimed in surprise, as if struck by lightning, staggering backward, his face devoid of color, even his body began to tremble.

Instantly, his whole person seemed to age significantly.

He stared intently at those flickering coordinates

No Human Realm!

How could it be!

At this moment, he was utterly in despair. After searching for so long, only the Three Judicial Departments in the Imperial City were left, and finally... he didn't find it!

He cannot accept this result!

"Why! Why!"

At this moment, Chen Xuan, as if he had lost his mind, suddenly erupted with such force that his neatly arranged long hair flew into the air, like someone gone mad.

"Calm!"

Zhan Tian shouted explosively, and with a single palm strike, suppressed Chen Xuan with the strength of the late stage Dao Realm of eighth level.

Outside!

Liu Sheng, who was originally playing with Xiaoqi, trembled all over.

Immediately looked in the direction of the Library Pavilion.

"What happened!"

Zhan Tian actually erupted with all his strength!

"You play here, Grandpa Liu will make a trip!"

As the words fell, his figure disappeared, and when he reappeared, he was already at the entrance to the tenth floor of the Library Pavilion, but he did not go in.

"Zhan Tian!"

He shouted loudly inward.

"It's nothing!"

Upon hearing these two words, the worry in Liu Sheng's heart was instantly relieved.

Zhan Tian certainly wouldn't lie to him.

But what happened inside!

In there!

Chen Xuan, who was suppressed, was sitting on the ground, his expression vacant.

Muttering to himself!

But fortunately, his aura had completely receded.

Zhan Tian walked to his side, having already vaguely guessed in his mind.

Previously, he thought it might be someone around him who came from the lower realm.

But looking at his reaction, it should be him instead, and the lower realm is about to be obliterated.

"I didn't expect you to come from the lower realm."

Zhan Tian's voice echoed in the room.

"Elder Zhan, why is it not there?"

Chen Xuan suddenly stood up, looking at Zhan Tian.

"If it's not there, then it means it has already been obliterated!"

Zhan Tian's voice struck his heart like a funeral bell.

"Poof!"

Chen Xuan spat a mouthful of blood, his face turning ashen.

He had considered this possibility just now, but forcibly dismissed it; he did not want to believe it.

How could it be!

The Human Realm still has a hundred years left, how many years have passed, how could it have already been obliterated?

"Take it easy, the obliteration of a realm is the will of Heaven, and there's nothing anyone can do about it."

Zhan Tian, uncommonly, offered him solace.

Also, the lifespans of martial artists are long, and Chen Xuan is still too young.

As time goes on, growing accustomed to people leaving, he would get used to it.

"Impossible!"

Chen Xuan shook his head resolutely, "When I came to the Supreme Domain, there was still a hundred years, it's been only at most twenty years now, definitely impossible to have been obliterated!"

He did not believe the Human Realm was obliterated!

And remained convinced that it was still there!

"Are you certain?"

Zhan Tian asked in a deep voice.

"Certain! Before I left, I looked carefully at the Human Realm, and the Emperor of the Human Realm also told me, there were still a hundred years, so I definitely wouldn't be mistaken!"

The obliteration of a realm also requires time.

At that time, the Human Realm was only just beginning; it couldn't possibly have been obliterated in such a short time.

Hearing this, Zhan Tian's expression turned hesitant.

"Elder Zhan, do you know something?"

Chen Xuan even disregarded Zhan Tian's status, stepped up to him, and tightly gripped his shoulders.

"Tell me! In this burial ground, I will kill all the people from other continents!"

Eager to know, he offered his biggest bargaining chip.

He could feel that Zhan Tian seemed to know something but hesitated.

"Sub-realm!"

Zhan Tian slowly uttered these two words.

"Sub-realm?"

What is that? He had never heard of these two words.

"Let go!"

Zhan Tian glared at him, the little brat's strength was quite considerable, he could feel a faint pain from his grip.

"Yes, yes..."

Seeing hope, Chen Xuan immediately released Zhan Tian, then eagerly asked, "What is a sub-realm? Elder Zhan, please tell me quickly!"

If it weren't for the fact that he couldn't match Zhan Tian, he would have wished to soul-search him directly.

"Why the rush!"

"Wait a moment!"

Then he closed his eyes and started communicating with Liu Sheng outside.

"This boy comes from a sub-realm!"

"Sub-realm?"

Liu Sheng at the entrance of the tenth floor was greatly shocked upon receiving this news.

Because the passages between sub-realms and the Supreme Domain were all sealed; this was done during the previous dynasty.

The reason for doing this was that the sub-realm was the foundation of the Supreme Domain, and it was said that many giants back then targeted the World Spirit of the lower realms for their descendants.

And the World Spirit of a sub-realm was of the highest grade.

Because of this reason, many World Spirits of sub-realms were forcibly taken, leading to the obliteration of entire realms.

Though there was Celestial Punishment, a Profound Realm was enough for a sub-realm which was inherently weaker.

Killing a Profound Realm to obtain a World Spirit from a sub-realm, it was the perfect bargain.

In the end, out of desperation, the previous dynasty killed several giants and expended enormous effort to completely seal the most critical sub-realm passages, thus deterring those individuals.

During Great Yu's era, each Emperor reissued this decree, reminding those with ambitions.

That was how no one dared to target the World Spirits of the lower realms again.
