"Shouldn't this place be completely purified? If it's purified over many years, it should be possible, right?"

Li Li shook his head with a wry smile: "Young friend Rong, you are unaware of this. This ancient battlefield of Yinshan is the site of a great battle between good and evil ten thousand years ago, and countless vengeful spirits and evil energy are buried underground. Even if we come to purify it every year, we can only suppress it temporarily."

Mo Bai put away the compass and said seriously, "Unless we can find the 'Nine Dragons Demon-Suppressing Stele' left over from the great battle and completely purify this land, the demonic energy will never be eradicated."

"The Nine Dragons Demon-Suppressing Stele?" Rong Jiaojiao asked curiously, feeling that the character "nine" appeared very frequently.

The Nine Dragons Demon-Sealing Formation, her Nine Revolutions of Demon Subduing, Mo Bai's Nine Dragons Demon-Subduing Brush, and now a Nine Dragons Demon-Suppressing Stele has appeared. What else will there be in the future?

Just as he was pondering, Li Li's voice came to explain: "Legend has it that it was a treasure that was jointly crafted by righteous cultivators back then. It could not only be used to suppress the main soul of the evil demon, but also to purify this battlefield. However, it disappeared after the great battle."

Zi Ling suddenly perked up her ears: "Master, something is coming!"

The ground began to tremble slightly, and a rustling sound came from afar. Countless skeletons crawled out of the ground, their eye sockets flickering with eerie green flames!

"They're skeleton puppets controlled by a demon!" Old Zhou drew his longsword. "Beware of their bone poison!"

With a flick of his white folding fan, several wind blades flew out, shattering the puppets in the front row. But the broken bones automatically reformed and continued to approach the group.

"Spell attacks are ineffective!" Rong Jiaojiao quickly took out three Heavenly Thunder Talismans. "Heaven and Earth are boundless, Heavenly Thunder vanquishes evil!"

Lightning and flames intertwined, and the bone demon was reduced to dust in the thunder. But even more puppets crawled out from the ground, their sheer number sending chills down one's spine.

Li Li swept his longsword horizontally, shattering the skeleton puppets wherever the sword energy passed, only to have them quickly reform. He said in a deep voice, "These puppets have been nourished by demonic energy for many years; ordinary attacks are unlikely to completely destroy them!"

A glint flashed in Mo Bai's eyes, and his folding fan suddenly unfolded, revealing intricate runes on its surface: "Borrowing the power of heaven and earth, wind, fire, thunder and lightning!"

In an instant, a gale arose, sweeping out with the power of thunder and fire, engulfing dozens of skeleton puppets and crushing them into dust.

Seeing this, Rong Jiaojiao had a sudden inspiration: "Ziling, use your lightning and fire to help me!"

Zi Ling understood, leaped into the air, and spat out a bolt of purple lightning.

Rong Jiaojiao simultaneously made a hand seal, and the Lingyuan Sword transformed into nine sword shadows: "Sword transforms into a swimming dragon, go!"

The sword light triggered lightning and fire, and nine lightning dragons formed a huge lightning net that enveloped the remaining skeleton golems.

In a flash of lightning, the puppets turned to ashes.

"Well done!" Mo Bai nodded approvingly.

Suddenly, the ground shook violently, and a giant bone demon composed of hundreds of skeletons burst out of the ground!

It was five zhang tall, and every bone was covered with blood-red runes.

Old Zhou's expression changed, and he stepped in front of Mo Bai: "At least at the peak of the Earth Master realm!"

The Bone Demon opened its massive maw and spewed out a cloud of dark green poisonous mist.

Li Li hurriedly formed a hand seal: "Golden light appears swiftly, covering and protecting the True Man!"

The golden protective shield barely blocked the poisonous fog, but it was corroded and hissed.

Old Zhou sneered, "A mere Earth Master dares to be so arrogant?"

Rong Jiaojiao felt ashamed. If she had encountered it alone, she would probably have had no choice but to run for her life. Only a Celestial Master would dare to speak so ill of a puppet at the peak of the Earth Master realm.

A cold glint flashed in Mo Bai's eyes, and the folding fan in his hand suddenly transformed into a pure white jade sword: "Nine Dragons Subduing Demons - Unsealing!"

Nine dragon patterns lit up on the sword, and the powerful spiritual energy fluctuations caused the surrounding air to freeze.

"Nine Heavens Respond to the Origin, Thunder God Descends to Earth, Slay Him!"

Nine dragon-shaped sword energies roared out, weaving into a golden net in the air, firmly trapping the Bone Demon General.

The Bone Demon let out a mournful roar, but it was unable to break free from the restraints containing the power of the Heavenly Dao.

Rong Jiaojiao seized the opportunity, and the sword technique of Lingyuan Sword suddenly changed: "Nine Revolutions of Subduing Demons - Second Form - Sword Piercing the Sky!"

Nine sword beams, like rainbows, precisely pierced nine vital points on the Bone Demon General's body. At the same time, Zi Ling spewed out purple lightning and fire, scorching the runes on the skeleton along with the sword beams.

"Celestial Master's decree, suppress!" Li Li summoned the Celestial Master's Seal and slammed it heavily onto the skull of the Bone Demon General.

Under the triple attack, the Bone Demon collapsed with a crash, turning into a pile of broken bones. Zi Ling quickly devoured the escaped demon seeds.

The crisis was temporarily averted, but Mo Bai suddenly groaned, and a trickle of blood spilled from the corner of his mouth.

Old Master Zhou quickly helped him up: "Young Master, you forcibly unsealed the Nine Dragons Demon-Subduing Sword, and the backlash was considerable."

What he wanted to say was that with him around, even a puppet at the peak of the Earth Master realm could be dealt with by him with one or two sword strikes. Why was he showing off?

However, since the other party is the young master, he still needs to give him some face.

Mo Bai waved his hand: "It's nothing, just a minor blood and qi reversal."

Mo Bai wiped the blood from the corner of his mouth, but his gaze remained sharp as a sword.

He gazed into the depths of Yinshan Mountain and said in a deep voice, "The real trouble is yet to come."

He then turned to Rong Jiaojiao and said, "Little girl, this is a great place to train. How about we have a competition to see who kills the most monsters?"

“No interest.” Rong Jiaojiao refused decisively and turned to Li Li, “Elder Li, let’s continue.”

Although Rong Jiaojiao thought Mo Bai's words made sense, she didn't want to compare herself with him. He was clearly better than her, yet he still dared to compare. He was shameless.

Li Li nodded with amusement and said, "Leave all the demonic spirits or puppets below the Earth Master realm to Rong Xiaoyou. I'll cover for you!"

This meant they were protecting her during her training, so Rong Jiaojiao quickly thanked them.

"You're welcome. It's always good for young people to experience more trials and tribulations." Li Li smiled slightly, his tone revealing the concern of an elder.

Mo Bai raised an eyebrow and said no more.

The group continued deeper into the ancient battlefield of Yinshan.

As they walked further and further away, the atmosphere around them became increasingly eerie and sinister.

The sparse vegetation had completely disappeared, replaced by patches of gray-black barren land, as if it had been corrupted by some evil force.

The air was thick with the stench of blood, making one frown.

Every now and then a skeleton puppet would crawl out, but Rong Jiaojiao easily dealt with it, while three leisurely figures followed behind her.

"The situation here is indeed worse than I imagined," Li Li said in a low voice, his eyes scanning his surroundings.

"Hmm, the bloodthirsty aura is getting stronger." Zi Ling perched on Rong Jiaojiao's shoulder, her little nose twitching as if she were sniffing out something. "Master, I sense an even stronger demonic aura, right ahead!"

"Watch out!" Before Li Li finished speaking, a huge black shadow suddenly rushed out from underground and headed straight for Rong Jiaojiao.

It was a huge black shadow, as big as a mountain, covered with a layer of sticky black mist, and emitting a nauseating stench.

"It's a demonic spirit at the Earth Master level!" Old Zhou exclaimed, quickly stepping in front of Mo Bai.
