After millions of years in the library, I became an Immortal Emperor.

Lin Fan looked at the black pool.

Ripples spread across the black pool, exuding an eerie aura, as if some great terror lurked beneath its unfathomable depths.

"So you can't get out."

Lin Fan said that he saw a pair of scarlet vertical pupils in the black pool, as well as a huge body that meandered like a hill. The black pool was a small world.

A small world specifically designed to suppress it.

But this little world is already on the verge of collapse.

"roar--"

A deep voice came from the black pool, as if it was angry because of Lin Fan's appearance, and it kept attacking the world seal.

His impact also affected the entire canyon, causing it to tremble.

Like an earth dragon turning over, the surrounding mountains and rivers are about to collapse into the canyon at any moment.

Above the canyon, a reclusive master gazed at the deep gorge with a solemn expression.

He didn't know what was happening below the canyon. Even though he had reached the Celestial Realm, he couldn't see through the canyon. He just felt that there was great terror below the canyon.

He dared not approach, much less go down.

Not long before, a scholar-like man walked down.

"Is it because of him?"

He murmured, feeling the crimson light surging from the canyon, his expression becoming even more solemn.

Before the Black Pool, Lin Fan remained calm. He then looked at the Great Song Emperor beside him, who seemed to be influenced by the Black Pool, as the demonic nature within him was almost taking over.

"It's time to wake up."

Lin Fan spoke, his words carrying a mysterious Dao principle that made his words law, and the humanity that was about to be extinguished within the Great Song Emperor instantly surged forth.

And that demonic nature was completely extinguished.

The Emperor of the Great Song Dynasty opened his eyes.

What came into view was the deep, dark pool and the soaring demonic aura. The next moment, as if he had thought of something, his expression changed drastically.

"Demon race!"

He spoke in a deep voice, his aura as a peak Dao-Slaying expert surged forth, but it was instantly suppressed by demonic energy.

The owner of this demonic aura is too powerful, having surpassed the Dao of Severing.

It is a sacred realm!

"puff!"

He coughed up blood and retreated, when he suddenly caught sight of a figure out of the corner of his eye, and his expression changed drastically.

The black pool rippled with waves, and a surging demonic aura permeated the air, seemingly threatening to obliterate everything around it, yet the figure remained standing there.

I am completely untouched by any demonic aura!

"this……"

He was utterly shocked. He had come at Lin Weiyan's request to suppress a demon about to be born, but he hadn't expected the demon to be so powerful.

The seal affected him, and on his deathbed, he finally understood that Lin Weiyan had already betrayed the human race and was sent out by this terrifying being in the black pool.

That was to lure him here.

The demons in the Black Pool want to use him to break the seal.

Despite his desperate efforts, he could only struggle to hold on under the corrosive power of that demonic force. But just when he was about to despair, that demonic force suddenly disappeared.

It was as if it had been erased from thin air by some force.

Then he saw the scene before him: a person standing quietly in front of the black pool, as if his back alone suppressed the entire land.

saint!

An unbelievable thought flashed through his mind.

The human race actually has a saint!

Suddenly, he seemed to realize something, and his expression changed again.

"Sage, a demon saint is being suppressed beneath this black pool. He is about to break through the seal. Quickly repair the seal and suppress him again."

he shouted.

But the figure in front didn't make any move, just quietly watching the scene before them.

Seeing this, he became even more anxious.

"Sage, do not underestimate this enemy. This demon saint's origins are extremely extraordinary. He is suspected to have the bloodline of the Azure Serpent of the demon race. His combat power is unprecedentedly strong, and ordinary saints cannot defeat him."

"There is also tens of thousands of years of accumulated malevolent energy, which must not be released."

He said that as the emperor, he was familiar with some of the most powerful bloodlines among all races.

The Azure Serpent is one of the three great imperial clans of the demon race. It has produced emperors in ancient times and is an imperial bloodline that has been passed down for countless years.

Even after he said that, the voice in front remained unmoved.

"Sage, quickly repair the seal!"

Sensing the immense demonic power surrounding him, he grew even more anxious.

He wanted to move forward, but he was forced back by that terrifying demonic power as soon as he took a step. This place was already shrouded in the demonic domain, and it was no longer something that he, a mere Dao-Slaying cultivator, could shake.

"It's over."

He watched this scene with a look of despair on his face.

The Azure Serpent—only those who truly understand it know how terrifying this bloodline is. Even an Azure Serpent at the first level of the Saint Realm can defeat Saints at the third or fourth level.

Not to mention that the giant python beneath this black pool could not possibly be someone who has just entered the Saint Realm.

On the contrary, the saint in front of the black pool may have just entered the saint realm. If the giant python of the sky breaks the seal, it will have no chance at all, and the entire land will be washed away in blood.

"Too slow."

Suddenly, he heard a voice; it was that of the saint.

This was the first sentence he heard from the sage. He stared at the churning black pool in front of him, and his words seemed to indicate that he had lost some patience.

Too slow?

What does that mean?

The next moment he witnessed a horrific scene.

The sage stretched out a hand, without a sword, yet he sensed a terrifying sharpness, as if a dreadful sword were piercing the black pool.

"Sage, no!"

He exclaimed in surprise, "The sage is actually helping the giant serpent break the seal!"

But it was too late for him to say it.

The hand fell into the black pool and casually swiped it. A cracking sound was heard, as if something had broken, and the surging demonic power in the black pool came to an abrupt halt.

The next moment, the entire canyon and even the surrounding mountains trembled, and a scarlet color filled the entire black pupil. It was actually a scarlet blood pupil.

The seal has been broken.

It's coming out.

The Emperor of the Great Song Dynasty trembled and collapsed to the ground.

It's all over.

"Human, I never imagined that you would be the one to help me break the seal in the end. I can forgive your offense and leave you with a whole corpse."

A sound came, the black pool tore open, and a huge shadow slowly rose from it.

Outside the canyon, the sky suddenly darkened.

The celestial being above the canyon's expression changed drastically. A terrifying demonic aura rose from below the canyon, and even a slight touch of it made him tremble with fear.

What a terrifying power this is!

"Damn humans, I, Cang Ming, have finally emerged."

It shouted, as if venting its anger over countless years.

Lin Fan watched this scene and suddenly laughed.

"Do you really think you can leave?"

He spoke casually, which startled even the giant python in the black pool. The Emperor of the Great Song Dynasty also looked at him, wondering what he meant.

"I let you out here just to make it easier to kill you."

Lin Fan said calmly.

As he finished speaking, the wooden sword on Lin Fan's back slowly came out of its sheath.

"call!"

The void was torn apart, and chaotic light gathered between the sword's edges. When this sword fell, it was as if two great worlds were cleaved apart.

The giant python looked at the sword and showed fear.

He tried desperately to dive down into the dark pool, but it was too late.

"The chains of rules, feared by Heaven..."

Only it could see the chains of rules that wrapped around Lin Fan's body when he swung his sword, layer upon layer, with no end in sight.
