Warning! A hidden dragon has emerged!

Looking at the dome that was about to collapse.

Qin Quan had a flash of inspiration and understood everything.

This is not an ordinary underground city at all, but a separate little world.

Since it's a small world, it must have an energy source to support its operation, and there must be great treasures here.

Qin Quan's eyes lit up instantly.

He disregarded his departed master and senior sister, turned around and sprinted towards the center of the city, frantically searching for the energy source that supported this small world, wanting to find it as soon as possible and then rush to the aid of the Wind and Rain Tower.

Just as Qin Quan's figure disappeared at the end of the street, a disheveled old man with gray hair appeared in the dark corner.

He walked slowly, leaning on a worn-out cane, his steps unsteady yet carrying an indescribable eeriness.

The old man walked straight to the entrance of Fengyuezhai.

This place is located right in the center of the entire Fengdu City, the core of the small world.

He slowly raised his head, and his originally cloudy eyes instantly turned bloodshot.

Then, it suddenly opened its blood-red maw and inhaled sharply the bloody aura permeating the city.

In an instant, the blood energy throughout the city seemed to be drawn by an invisible force, solidifying into physical form and transforming into streaks of blood that surged wildly into the old man's body.

The corpses on the ground shriveled and decomposed at a visible speed, turning into piles of white bones in the blink of an eye, leaving not a trace of flesh or blood.

In a short while, he absorbed all the blood energy in the city, and the cracks in the sky grew larger and larger, with sand and soil falling down like the Yellow River bursting its banks.

It crashed to the ground with a deafening roar, and the underground city, which had existed for countless years, instantly became desolate and lifeless.

"belch!"

The old man let out a satisfied burp, his aura surged, his previously hunched body straightened a bit, and his sinister gaze was fixed on the direction where Qin Quan had disappeared. A wicked and eerie smile appeared on his lips.

Qin Quan seemed to sense something, and alarm bells rang in his mind.

Almost instantly, he turned around and teleported to the entrance of Fengyuezhai, where he met the old man's eerie smile and recognized him at a glance.

"Yang Zhentian!"

Qin Quan's eyes were icy cold, and his spiritual energy surged wildly around him.

"Hehehe! Thank you, Fellow Daoist Qin, for replenishing my blood and energy. My strength has improved once again!"

Yang Zhentian chuckled strangely, his voice hoarse, his face full of mockery.

"So it was you who was behind this."

"Isn't it obvious?"

Yang Zhentian said it frankly.

Suddenly, he raised his hand, and Huanji, Meka, and Langshan appeared out of thin air, standing in front of him.

At this moment, their eyes were vacant and their faces were expressionless, like marionettes.

"Kill him!"

Upon hearing Yang Zhentian's command, the three immediately charged towards Qin Quan, their movements stiff but carrying a fierce, fearless determination.

Taking advantage of the opportunity, Yang Zhentian turned around, transformed into a black shadow, and quickly fled towards the city gate.

In the blink of an eye, they disappeared into the darkness, giving Qin Quan no chance to fight back.

"court death!"

Qin Quan no longer hesitated, raised his hand and summoned the Pure Yang Sword. Golden spiritual energy enveloped the sword, making it shine brightly.

He leaped into the air and unleashed a sword strike. The violent pure Yang sword energy, like a hundred-meter-long curved blade, slashed towards the three of them with a world-destroying momentum.

puff!puff!

Meka and Langshan were already weaker than Qin Quan, and now that they were puppets, they were completely unable to withstand this sword strike.

The moment they collided with the sword light, their bodies were cut into four pieces.

Blood splattered everywhere, and he died on the spot.

Only Huan Ji staggered back a few steps, blood spilling from the corner of her mouth, but her eyes remained vacant, showing no sign of pain.

"As expected of the person who sealed my sister's memories, they do have some skill."

Qin Quan's eyes turned cold, but he wasn't surprised.

But in that brief delay, Yang Zhentian had vanished without a trace, leaving no trace of his presence.

The cracks in the sky had spread to the entire city of Fengdu, and sand poured down, burying half of the city, which was in danger of collapsing at any moment.

Huan Ji remained silent, seemingly oblivious to the pain, relentlessly pressing forward, drawing her sword to strike Qin Quan once more.

"Overestimating yourself!"

With the situation becoming increasingly urgent, Qin Quan no longer intended to hold back. He immediately mobilized the power of his dantian, causing the nine golden cores within his body to circulate wildly.

Pure golden spiritual energy surged forth, converging on the Pure Yang Sword along the eight extraordinary meridians, shining brightly and exuding an aura of world-destroying power.

Just as Huan Ji's longsword was about to pierce his chest, Qin Quan suddenly raised his hand, gripped the hilt tightly with both hands, and chopped down with force.

One sword cleaves the heavens!

Stab it!

The sword light tore through the sky, accompanied by a piercing sharp sound, and instantly engulfed Huan Ji.

Huanji didn't even have a chance to resist before she was completely overwhelmed by the sword light.

Their souls and bodies were annihilated, leaving no trace.

Not even a trace was left.

At the same time, the entire city of Fengdu seemed to have been hit by a powerful earthquake, with the ground shaking and dust flying everywhere.

The Fengyuezhai collapsed instantly, and a bottomless pit appeared out of thin air on the ground.

Then, a sliver of light slowly emerged from the deep pit, growing brighter and brighter.

A moment later, a golden token, engraved with ancient patterns, slowly rose from the deep pit and hovered in front of Qin Quan, exuding an ancient and profound aura.

Without the slightest hesitation, Qin Quan reached out and grabbed the token.

Looking down, two large gilded characters were clearly engraved on the front of the token.

Kunlun!

"I never imagined the second Kunlun Token would be hidden in Fengdu City!"

Qin Quan was overjoyed. He had searched high and low without finding it, but it came to him without any effort.

To find such a treasure in this wretched place.

However, before he could rejoice, the entire city of Fengdu began to collapse, and the sand and gravel above poured down like a flood, already submerging his feet.

He looked around but found no other treasures. A pang of regret crossed his mind, but he dared not delay any longer.

We must leave this place.

Qin Quan couldn't help but sigh, gripped the Kunlun Token tightly, channeled all his spiritual power, leaped into the air, and raced wildly toward the city gate.

The sand and gravel behind us poured down like a curtain of rain, and the huge sound, like muffled thunder, echoed in our ears.

Above the surface, the Death Desert has completely changed its appearance.

The entire desert resembles a giant cone-shaped hourglass, with yellow sand flowing like a torrent into the collapsed underground city below.

The roar was deafening, and the smoke and dust blotted out the sun.

Suddenly, with a whoosh!

Qin Quan transformed into a golden streak of light, bursting out from the giant crater. His spiritual energy surged, and with a sharp whooshing sound, he instantly soared into the sky, hundreds of meters high.

"Damn, that was close, I was almost buried alive."

He hovered in the void, looking down at the desert below that was constantly collapsing and being swallowed by the yellow sand. He patted his chest with lingering fear and secretly rejoiced.
