"Why did the human race become enemies?"

Li Yu felt that if he figured out this problem, it must be the key to breaking the deadlock.

"actually……"

Mo Bai shrugged his shoulders and spread his hands, "Actually, we don't know. What passed down from ancestors in the clan is that the human race is already an enemy."

“As for the reason…”

Mo Bai glanced at the other three demon emperors and nodded, "The ancestors left the secret realm of the Heavenly Demons. Brother Ao Xuan is a pure blood dragon clan, and he will definitely be able to open the secret realm. Maybe the truth is in it."

"Yes!"

The demon emperor "Yi"'s tough face showed a hint of hope, "Since the failure of the Battle of Heaven 30,000 years ago, the bloodline of the Heavenly Demon has been zeroed and countless inheritances have been cut off. Open the secret realm of the Heavenly Demon and take out the things left by our ancestors, you will definitely be able to find out the truth."

"Let's go, let's open the secret realm of the Heavenly Demon."

The Demon Emperor "Li" and the Demon Emperor "Qing" also looked at Li Yu with a look of hope, looking forward to Li Yu being able to open the secret realm of the Heavenly Demon.

"Is the secret realm of the Heavenly Demon?"

Li Yu nodded slightly, and became a little curious about the secret realm of the Heavenly Demon.

With Li Yu's current strength, even if the four demon kings want to join forces to cheat him, they can directly suppress him.

As for whether there are any restrictions in the Tian Yao Secret Realm, as long as the system scans it, no matter how strong the restrictions are, they will be broken completely.

With confidence in his heart, Li Yu had already made a decision, "Since I need pure blood to open the secret realm of the Heavenly Demon, I naturally have no choice."

"Very good!"

Hearing Li Yu's reply, the four demon emperors all looked happy.

"Thank you brother Ao Xuan."

"It is really gratifying to see the light of day in the ancestors' inheritance."

"Yes! After opening up the secret realm of the Heavenly Demon and obtaining the blood inheritance of our ancestors, our clan can continue again!"

The four demon emperors smiled happily.

"Brother, the secret realm of the Heavenly Demon is under the Heavenly Demon Hall, let's go."

Mo Bai greeted Li Yu and walked behind the Heavenly Demon Hall.

After passing through the hall, everyone stopped by a pool behind the hall.

"This pool leads to the Yin River underground. If we dive along the Yin River, we can reach the entrance to the Tian Yao Secret Realm."

Mo Bai explained to Li Yu, and waved his hand and the dragon descendants' natural water-control magic power was used, leading everyone to enter.

"Brother Ao Xuan, this underground yin river is covered with ban talisman arrays. Follow me and don't touch other places."

Mo Bai reached out to hold up a pearl, illuminated the surroundings, then reminded Li Yu and stepped forward.

"Yeah, I get it."

Li Yu nodded and followed Mo Bai along the Yin River underground.

But I gave an instruction to the system in my heart, asking the system to scan the banned talisman array arranged in the Yin River.

Although I have the confidence to suppress the four demon kings with my own strength, it is naturally the best way to respond to anything.

Advance along the Yin River underground, after half an hour, everyone came to an underground lake.

With a "slam" sound, the water broke out.

What appeared in front of everyone was a simple and heavy stone door about ten feet high.

"Brother Ao Xuan, this is the entrance to the Heavenly Demon Secret Realm."

Mo Bai waved his hand and embedded the pearl into the rock above the stone gate. Under the bright white light, the scene on the stone gate was clearly revealed.

"Is this the entrance to the Heavenly Demon Secret Realm?"

Li Yu glanced at the stone gate and nodded slightly.

This ancient stone door has various relief images of demon races carved on the door frames on both sides, each appearing vividly and extraordinary.

On the two stone doors, there are also reliefs of dragon, phoenix, unicorn and white tiger black trunks. In addition, countless runes are engraved. Each rune is outlined with a dark golden spiritual ink.

“Those inks…”

Li Yu glanced at the dark golden spiritual mo that was outlining the runes, his eyes condensed, and suddenly it appeared that it was not spiritual mo at all, but blood!

"System, scan the runes on the stone gate, analyze runes, and determine the runes' efficacy."

Through the "Yan Dzi", he collected the martial arts information of various sects, and combined with the accumulation of several worlds, Li Yu glanced over and saw the talisman array on the stone gate himself.

But... be careful in everything so that you won't capsize in the gutter.

"Scan and parsing are completed."

The system passed the conclusions of the scanning analysis. Compared with the two, Li Yu found that his own judgment was not problem.

"It's a bloodline sealing talisman array. As long as there is the same bloodline, the seal can be opened."

After confirming that he would not be cheated, Li Yu then walked to the stone gate.

"Everyone, I'm going to open the secret realm of the Heavenly Demon."

Li Yu greeted the four demon emperors, stretched out a finger, and pointed it into the dragon-shaped relief on the stone gate relief.

A drop of purple-gold true dragon blood came out of his fingertips and dripped into the dragon's mouth.

“Buzz…”

After the blood of the real dragon dripped into the embossed dragon's mouth, a brilliant golden light shone on the dragon-shaped relief. From the dragon's head to the dragon's tail, a golden true dragon shape appeared on the stone gate.

"Okay! OK! Great!"

Seeing the scene on the stone gate, the four demon kings were both excited and happy.

“Buzz…”

A trembling sound rang out from the stone gate, and the golden dragon shadow swam like a little bit of golden light, and a string of characters formed on the stone gate.

"True Dragon Talisman?"

Seeing this string of characters, Li Yu frowned slightly, "Is this blood sealing talisman array even created this one?"

This string of true dragon talismans is actually the secret text of the true dragon clan.

The ancestors of the demon clan who set up this bloodline ban must have considered that their descendants might be killed, and then their bloodlines were extracted to open the secret realm portal.

If this is the case, then outsiders will naturally not recognize this string of secret texts, and it will be impossible to open the secret realm.

"But... although I have the blood of the real dragon, I can't recognize the secret texts of the dragon clan in this world!"

Li Yu was so depressed!

"Brother Ao Xuan, open the door quickly!"

The more impatient demon emperor "Li", shook his fiery red head and urged Li Yu.

"Yes! Just recite the mantra and spell to open the door."

The demon king "Qing" also spoke and urged Li Yu.

The demon emperor Mo Bai and the demon emperor "Yi" did not speak, but just looked up at Li Yu, and the expression on their faces could not be seen to change.

"There is such a change in this magic circle? This is a bit troublesome."

Let the system directly extract the spiritual power from the sealed magic array on the stone gate, so that it can naturally break the magic array and enter the secret realm of the Heavenly Demon.

But in this way, Li Yu's identity will definitely be suspected. The four demon kings are not easy to fool. Once they have doubts, they will definitely take action without saying a word.

Although it is not difficult for Li Yu to directly defeat the four demon emperors, it is difficult to obtain real information in this way.

Who knows if there is really information left by the ancestors of the demon clan in this secret realm of Heavenly Demon Realm? After all, the information in the secret realm of Heavenly Demon Realm was all told by the Demon Emperor, who knows the true or false?

Even this secret realm of the Heavenly Demon may be the way the four demon emperors detect Li Yu's identity.

The ancestors were refined into puppets and came back from time to time to time to brush the map. If these people were not careful, then there would be ghosts.

"The Demon King is indeed not simple? The warm greeting before, with an undoubted look, I'm afraid it's just a show."
