Transmigrated Villain: Starting by Removing the Female Lead's Supreme Bone

That ancient book, which records five secret locations, is the key to breaking the Demon King's seal.

However, the whereabouts of that ancient book are unknown.

After asking around, the three of them finally found a centenarian in a remote village.

It is said that this old man is the only survivor who personally witnessed the sealing of the demon king.

"Senior, have you ever heard of an ancient book that records the secret location of the Demon King?"

Su He asked respectfully.

Upon hearing this, the old man's aged face showed a hint of reminiscence.

"Ancient book... are you talking about the Record of the Demon King?"

The three of them were startled when they heard the name.

"The Record of the Demon King? Senior, are you familiar with this ancient book?"

Lin Yan asked excitedly, his voice trembling slightly.

The old man nodded slowly, his gaze becoming profound.

"Back then, I followed the seniors of the five major sects and participated in the battle to seal the Demon King."

"That battle was incredibly fierce. We suffered heavy losses, but we ultimately managed to suppress the Demon King."

"And that Record of the Demon King was personally recorded by the five sect leaders after the Demon King was sealed."

"It records in detail the origins of the Demon King and the locations of the five secret sealing sites. It can be said to be the key to breaking the Demon King's seal."

Su He and the others were overjoyed to hear this.

Surprisingly, they actually found a witness to the incident!

The old man's words undoubtedly confirmed the existence of the Demon King's Record.

"Senior, do you know the whereabouts of the Demon King's Record?"

Ni Chang asked anxiously, her beautiful eyes filled with worry.

The old man sighed, his tone somewhat somber.

"I'm afraid no one knows who it ended up in."

It seems that finding the Demon King's Record will not be an easy task.

"but……"

The old man suddenly changed the subject, his gaze becoming sharp.

"Although the whereabouts of the Demon King's Record are unknown, I do know of a place where the soul of a Demon King is sealed."

"Back then, I personally witnessed the five sect leaders sealing the Demon King's soul there."

Su He and the others were overjoyed and repeatedly asked, "Where is it? Please enlighten us, senior!"

The old man slowly got up and walked to a box that had been sealed away for a long time.

He opened the box and took out a yellowed map.

"This map marks one of the places where the soul of a demon king is sealed."

"Back then, the five sect leaders entrusted me with the map for safekeeping, instructing me never to reveal even a trace of it."

"But now that the Demon King has reappeared, the world is in imminent danger. I think it's time to pass this secret on to you young people."

The old man solemnly handed the map to Su He.

Su He took the map and felt a sudden weight in his hand.

"Thank you for your guidance, senior! We will certainly live up to your expectations and do our utmost to slay the demons!"

Lin Yan and Ni Chang also thanked them repeatedly.

If it weren't for the old man's generous help, they probably would have had to grope in the dark for a long time.

After saying goodbye to the old man, the three of them found a secluded spot and began to study the map.

On the map, a rugged mountain range was drawn.

At the center of the mountain range, a striking red dot is marked.

Beside it, there is a line of smaller characters: The Demon King's soul is suppressed here.

"Is this the place where the Demon King's soul is sealed?"

Lin Yan murmured, his gaze sweeping back and forth across the map.

"Judging from the terrain, it should be in the heart of the Black Cloud Mountains. The terrain there is treacherous, and monsters roam freely. It has always been a place rarely visited by humans."

Su He nodded, his brows furrowed.

"It seems that the five sect leaders deliberately chose such a remote place to seal the Demon King's soul back then."

"I'm afraid it's to prevent someone from accidentally entering and triggering the seal."

Ni Chang also looked solemn.

"This trip will likely be extremely dangerous. We must be fully prepared."

The three of them studied the map carefully again and determined the general route.

Then, they began to pack their bags, planning to set off for the Black Cloud Mountains early the next morning.

"This is it."

Looking up, Suhe could see a patch of emerald green lake in the center of the valley.

The lake water was crystal clear, yet it exuded an eerie atmosphere.

"The map says that the Demon King's soul is sealed in a cave at the bottom of this lake."

Lin Yan said in a deep voice, his gaze sweeping over his surroundings.

"It seems we must dive to the bottom of the lake to find the Soul-Sealing Formation."

"This lake is probably not ordinary. We must be careful."

The three exchanged a glance, and the next moment, they leaped into the lake and began to dive to the bottom.

The lake water was icy cold, but the three of them continuously protected themselves with their inner strength.

They swam through the water and soon reached the bottom of the lake.

The bottom of the lake was dark and gloomy, with a faint eerie aura emanating from it.

In the very center of the lakebed, there is a huge cave.

Clearly, this is the place where the Demon King's soul was sealed away back then!

Su He and the others were overjoyed and quickly swam over.

But the instant they entered the cave, a powerful force suddenly blasted them away.

"what!"

The three of them tumbled in the water, nearly knocked unconscious by the force.

"What a powerful barrier!"

Lin Yan gritted his teeth, his face turning somewhat pale.

"It seems the five sect leaders really went to great lengths to seal the Demon King's soul securely back then!"

Su He also had a solemn expression, his gaze sweeping over the array surrounding the cave.

"These formations and runes contain extremely powerful spiritual energy. Ordinary methods would probably be insufficient to break them."

"I have an idea. Why don't the three of us join forces and use sound to attack the formation? Perhaps we can break through the barrier!"

Su He and Lin Yan were taken aback for a moment, then understood.

"Alright! We'll do as Fairy Rainbow says!"

The three sat cross-legged in the water and began to gather their inner strength.

The next moment, a powerful gust of air surged from their bodies.

With a wave of her jade-like hand, Ni Chang unleashed waves of sound that surged towards the cave.

At the same time, Su He and Lin Yan also let out a long roar, and streaks of sword energy intertwined with the sound waves.

Instantly, the lakebed surged with waves and the currents became turbulent.

Countless streams of air swirled and roared around the cave.

The formations and runes gradually dimmed under the impact of this power.

"It's done! The barrier has been broken!"

Lin Yan was overjoyed and rushed into the cave first.

Suhe and Nishang followed closely behind, cautiously observing their surroundings.

Inside the cave, there was a huge magic array.

In the center of the magic circle, there was a cloud of dark mist, exuding an extremely evil aura.

"That is... the Demon King's soul?"

"It seems that the seal from a hundred years ago is now in grave danger."

"We must quickly and completely destroy the Demon King's soul to eliminate this threat!"

Just as the three were about to step forward, the cave suddenly began to shake violently.

The black mist within the magic circle began to surge wildly, seemingly about to break free of its restraints at any moment.

"Oh no! The seal is about to break!"

Lin Yan was shocked and quickly channeled his inner strength to try and stabilize the formation.

But that demonic aura was far too powerful.
