Although Qiu Mobai's claws were blocked by the water curtain, the sinister and domineering demonic energy continued to erode the energy of the water curtain.

A cruel glint of pleasure flashed in his eyes: "You little beast, you dare to be so insolent in front of me with such paltry skills? Die!"

As he spoke, he suddenly raised his other hand, his five fingers spread wide, and in his palm, a jet-black, constantly rotating energy vortex rapidly condensed! The vortex emitted a chilling suction force, and the surrounding light seemed to be swallowed up by it!

"It's the Demonic Soul-Devouring Palm!"

Xiao Feng's heart skipped a beat. This was one of the most representative moves in Qiu Mobai's demonic arts, extremely vicious and specifically designed to devour living souls!

"Old man, you're finally willing to use your real skills!"

Xiao Feng sneered inwardly, but outwardly he feigned extreme horror and shouted, "You... what kind of technique is this? Such an evil aura! This is not a technique of the immortal sects at all!"

With this shout, Xiao Feng used all his strength. His voice pierced through the roar of the energy collision and clearly spread throughout the entire study area, even reaching the courtyard outside!

Qiu Mobai's expression changed drastically!

He was enraged by Xiao Feng and was eager to kill to silence him, so he subconsciously used his most proficient demonic art, forgetting that this was the Immortal Cloud Sect and there were countless disciples outside!

The characteristics of this Demonic Soul-Devouring Palm are too obvious! Once it is seen, his righteous image, which he has painstakingly cultivated over the years, will be ruined!

"You... what nonsense are you talking about!" Qiu Mobai was both shocked and angry, but his hand movements involuntarily froze.

It was that moment of hesitation!

A glint of light flashed in Xiao Feng's eyes as he seized this fleeting opportunity!

He abruptly withdrew the "Water Curtain Heavenly Splendor," and at the same time, the immortal power within his body circulated in a mysterious trajectory, his hands once again rapidly forming hand seals!

"The wind's picking up, let's get out of here!"

Xiao Feng shouted in his heart, turned tail and ran!

But he ran not the way he came, but deeper into the study! That was his true destination!

Qiu Mobai was taken aback by Xiao Feng's sudden change of tactics. After realizing what was happening, he was furious!

That little brat, all that desperate fighting he did just now was an act! His goal wasn't to fight head-on at all, but to force himself to use his demonic powers, then take the opportunity to escape, all while shouting and yelling to make a scene!

"You little beast, don't even think about running away!"

Qiu Mobai roared, no longer caring about hiding his demonic arts. His black aura surged again, and he moved even faster than before, chasing after Xiao Feng in the direction he had fled!

He had only one thought in mind: to capture Xiao Feng and kill him to silence him before anyone else arrived! Otherwise, the consequences would be unimaginable!

As the corridor deepened, the light grew increasingly dim.

Relying on his familiarity with the terrain, Xiao Feng zigzaggled around at lightning speed.

"Die!" Qiu Mobai suddenly accelerated, his withered claws reaching out again. This time, the black energy condensing on the claws was even more intense, vaguely forming a hideous ghost head phantom, opening its blood-red maw and biting fiercely at Xiao Feng's back!

This strike contained the full power of his late-stage Foundation Establishment stage! He was determined to kill him in one blow!

Sensing the deadly danger behind him, Xiao Feng's hair stood on end!

He suddenly rolled over like a lazy donkey and fell forward in a sorry state!

"Sizzle!"

The black, ghostly aura grazed his back, tearing a long gash in his blue Taoist robe and leaving several deep, bone-revealing claw marks! A searing pain shot through him instantly, and the chilling demonic energy seeped into his body through the wound!

"Pfft!" Xiao Feng spat out a mouthful of blood, his face as pale as paper.

But with the force of his lunge, he rolled right to the wall at the end of the corridor!

Soon, Xiao Feng smelled a certain aura here!

Demonic energy?

He didn't bother wiping the blood from the corner of his mouth. Enduring the excruciating pain, he slapped the seemingly ordinary wall with his blood-stained palm!

"Buzz—!"

The wall trembled slightly, and the originally tightly sealed stone wall slowly caved inward, revealing a dark hole that could only be passed through by one person!

The entrance to the secret room is open!

"You little beast, how dare you!"

Qiu Mobai's eyes widened in fury upon witnessing this scene!

What's inside is his biggest secret, and he must never let anyone know!

He lunged forward frantically, trying to stop Xiao Feng from entering.

But Xiao Feng turned around, gave him a bloodstained, provocative smile, and then plunged headfirst into the dark hole without hesitation!

"Qiu Mobai, your death is near!"

Xiao Feng's voice came from the secret room, sounding weak but full of joy.

"Aaaaah! Get out here and die!" Qiu Mobai, acting like a madman, slammed his palm hard against the stone wall that was about to close!

"Boom!"

With a loud bang, the entire corridor shook violently, leaving a deep black palm print on the stone wall, shrouded in demonic energy.

But the stone wall was made of a special material, and it withstood his angry blow, slowly closing and completely locking Qiu Mobai outside!

At this moment, several disciples wielding long swords and dressed in the robes of the Immortal Cloud Sect finally arrived at the corner, just in time to witness the terrifying scene of Qiu Mobai frantically attacking the wall, his body shrouded in black mist!

Everyone was stunned!

"As expected, you are a demonic cultivator!"

"A leading inner disciple asked, his voice trembling, his face filled with disbelief," a voice that seemed to say, "I can't believe it."

Qiu Mobai suddenly turned around, his bloodshot eyes, filled with violent killing intent, staring intently at them!

"Get out!" A roar like that of a ferocious beast came from Qiu Mobai's mouth!

The disciples were so frightened that they scrambled backward, not daring to ask another question!

They felt as if Elder Qiu before them had transformed into a monstrous figure who would devour anyone who dared to harm them!

Qiu Mobai stared at the tightly closed stone wall, then at the fleeing figures of his disciples, his face so gloomy it could drip water.

He knew things were in trouble!

Meanwhile, inside the secret room.

Xiao Feng leaned against the cold stone wall, panting heavily. The excruciating pain in his back made him almost unable to stand.

He casually tore off a piece of his sleeve, hastily bandaged the wound, then struggled to his feet, his gaze fixed on the depths of the secret room.

The secret room was small, only about ten feet in diameter, and the air was filled with a faint smell of blood and herbs.

In the very center stood a bronze alchemy furnace, about half a person's height, its body covered with ancient patterns, and faint black mist swirling around it. Beneath the furnace, flames seemed to still flicker.

Beside the alchemy furnace, there were scattered bones, some human and some beast, all white and terrifying!

His feeling was right; this was indeed demonic energy!

Sure enough, this old bastard was using his soul and blood essence to refine an evil pill right here!

A hint of disgust flashed in Xiao Feng's eyes.

He walked to the alchemy furnace, suppressing his discomfort, and carefully observed the runes on the furnace.
