Mo Tian concentrated and exerted his strength. Surrounded by blue light, he raised his arm forward, his veins bulging.

He slowly raised his arm, and the iron cage opposite him was lifted by the blue light, three feet off the ground. Then he pulled it back towards him, and the iron cage left the black pool, turned towards the shore, and hung in the air...

"Lower!" Mo Tian uttered a single word, and with a clang, the iron cage slowly descended to a clearing about five meters to his left, beside rubble. Mo Tian breathed a sigh of relief and was about to step forward...

"Mo Tian, ​​look!" Just then, a hand reached out and grabbed Mo Tian. It was Mercury. He looked somewhat nervous and turned his head to look at the black pool on his left...

"Glug glug!" A sound of churning water came from the black pool. Following Mercury's gaze, a wave more than a meter high was seen rising in the middle of the pool.

"Hmph, you demon king, you think you've gotten out?" Mo Tian's eyebrows shot up, he turned around, raised his hand and activated his spiritual power...

Mercury, seeing this, also stood aside and gathered spiritual power in his fingers.

"Move the stones to fill the pond!" Mo Tian shouted, and almost simultaneously with Mercury, at the flash of spiritual light, he pulled his arm down towards the stone wall in front of him.

With a series of loud rumbles, the rocks hanging on the stone wall fell into the water, filling the black pool in a short time. Mo Tian steadied himself and withdrew the spiritual light from his fingertips. "From now on, this will be the Black Serpent Cave. You will guard this place. Consider this a chance for you to repent."

On the black pool, the gravel lay silently, and the dust gradually settled.

One wave subsides only for another to rise.

"Awoo!" At this moment, Wan'er, who was trapped in the iron cage by resentment, had purple lips, was covered in cold sweat, and her shoulders were trembling.

"Holy Maiden!" The four spirit maidens—Li'er, Jiu Yue, Xiao Yu, and Xiao Mei—flew forward from both sides. However, before they could get close, a black and white, malevolent light shot out from the iron bars of the cage.

The four spirit maidens screamed, "Ahhh..." as they were thrown back by an extremely cold and strange force, and "plop plop..." they all fell behind Mo Tian and Shui Xing.

Xiaoyu, who had not yet fully recovered, was still hanging from a rock...

Mercury, who was standing nearby, quickly ran over and carefully helped her down. Fortunately, she only suffered a minor injury to her arm.

Before he could go there, Mo Tian glanced around and noticed the secret at the iron cage bars. He took a deep breath and rushed forward.

Sure enough, as soon as he approached the iron cage, he felt a chilling aura. Mo Tian's eyes darkened, and he raised his hand to his lips.

He bit his finger hard, and a drop of bright red blood flowed down the tip of his index finger.

Mo Tian stretched out his bloodied finger and slid it across the iron bars in front of him. A strange sizzling sound came from the friction, as if something was burning. Soon, black smoke began to rise from all the iron bars, from near to far.

Mo Tian remained calm, spread his fingers wide, and pulled back forcefully. All the black smoke, as if drawn by a magnet, gathered and swirled in Mo Tian's palm. Soon, the iron railing, which had looked rusty, became clear and bright.

It seemed that the countless black mists had just swept away the filth from the iron rod. In Mo Tian's palm, as the blue light spun, a black sphere, roughly the size of a baby's head and emitting a foul odor, quickly appeared in the center of the blue light.

"Ahhhhhhh..." As the sphere took shape, black mist swirled in Mo Tian's palm.

Around the sphere, countless skulls of varying sizes, overlapping and terrifying, suddenly sprang forth...
