My brother is Shi Hao

Shi Yi's eyes flashed with determination. He solemnly placed the torn letter in his arms. "The clue is in this letter. The fatal weakness of the Netherworld Cult Leader and the forbidden technique he practiced require us to go deep into the tiger's den to find the answer."

Upon hearing this, Shi Hao nodded heavily, his eyes filled with determination. "Alright! Let's go meet this Netherworld Cult Leader. I want to see who he is!"

So, Shi Yi and Shi Hao summoned Taoist Xuanfeng and a team of elite disciples from various sects. Following the implicit hints in the letter, they tracked the trail all the way and finally arrived at the lair of the Netherworld Lord - a forgotten ancient castle.

The castle stood in a desolate valley, surrounded by gusting winds and the constant howling of ghosts and wolves, as if it were the gateway to hell. The castle's walls were mottled and covered with dark green vines, exuding a gloomy and terrifying atmosphere.

"Is this the lair of the Netherworld Lord? It is indeed an evil place!" Taoist Xuanfeng frowned as he looked at the scene in front of him.

"Everyone be careful, everything here is weird, don't take it lightly." Shi Yi reminded.

Everyone approached the castle cautiously, only to see that the castle gate was tightly closed and carved with hideous ghost patterns, as if it would come alive at any moment.

"Let me open it!" A burly man walked forward, swinging a huge axe and chopping it hard on the castle gate.

"boom!"

With a loud bang, the castle gate did not move at all, but the man was knocked back several steps by a powerful recoil force, and a mouthful of blood spurted out.

"What's going on?" Everyone was shocked.

"This gate is protected by a powerful restriction. Brute force cannot open it." Shi Yi walked forward and carefully observed the restriction on the gate, frowning. "It seems that we need to find a way to break the restriction."

Just when everyone was at a loss, Shi Hao suddenly felt a palpitation. He suddenly raised his head and looked into the depths of the castle, and an ominous premonition came to his heart.

"careful!"

Before Shi Hao could finish his words, an eerie laugh suddenly rang out from the castle. Then, countless black shadows shot out from the castle and pounced on everyone like black lightning.

"Oh no, these are the minions of the Nether Lord, everyone be careful!" Taoist Xuanfeng shouted upon seeing this and took the lead to meet them.

A fierce battle erupted instantly. Shi Yi and Shi Hao fought side by side, their double pupils and the power of the Supreme Bone combining to defeat the shadows one by one. However, the shadows seemed endless, surging forward one after another, and everyone gradually felt a little powerless.

"This is not a solution. We need to find the Nether Lord as soon as possible!" Shi Yi said to Shi Hao while resisting the attack of the black shadow.

Shi Hao nodded and looked around, trying to find a way out. Suddenly, his eyes fell on a tall tower in the center of the castle. The tower was completely black, like a sharp sword piercing the sky, emitting a heart-pounding aura.

"That tall tower..." Shi Hao pointed at it and said to Shi Yi, "I have a feeling the Netherworld Cult Leader is right there!"

"Okay, let's charge in!" A gleam of light flashed in Shi Yi's eyes, and he made the decision immediately.

However, just as they were about to charge the tower, the ground suddenly shook violently, and deep, bottomless cracks appeared beneath their feet... The earth groaned with a piercing sound, and the cracks spread rapidly like a spider web, swallowing everything around them. Shi Yi quickly grabbed Taoist Xuanfeng beside him, and the power of the Supreme Bone surged through Shi Hao's body. Golden light burst forth like the sun, abruptly halting the spread of the cracks.

"That was close!" Taoist Xuanfeng was still in shock. Looking at the bottomless abyss beneath his feet, he felt a chill on his back.

"This is a trap set by the Nether Lord. Be careful!" Shi Yi warned in a deep voice. Deep runes flowed in his pupils, gazing at everything around him. He discovered that the castle's layout held a hidden secret. Every wall and every floor tile was engraved with strange runes. These runes connected to form a massive formation, and they were now at its core.

"These runes..." Shi Hao stared at the runes on the ground with a frown. He felt a familiar breath, which seemed to resonate with the supreme bone in his body.

"Can you crack it?" Shi Yi asked. He knew that Shi Hao had an extraordinary talent in formations.

Shi Hao closed his eyes and immersed his mind in his body, feeling the fluctuations of the Supreme Bone. After a moment, he opened his eyes, his eyes flashing with enlightenment. "I understand, these runes are used to suppress the power of the Supreme Bone. As long as I use the power of the Supreme Bone to guide it in the opposite direction, I can break this formation!"

After saying this, Shi Hao sat cross-legged, forming seals with his hands. The power of the Supreme Bone formed a golden shield around him, counteracting the runes on the ground. As time passed, the golden light grew stronger, and the runes on the ground began to dim, eventually disappearing completely.

"It's done!" Shi Yi's eyes flashed with joy. He pulled Shi Hao up and said, "Come with me. I know the way to the Netherworld Cult Master!"

Shi Yi led everyone through the intricate castle, exerting the power of his double pupils to the extreme, avoiding one deadly trap after another. Finally, they came to a huge stone gate.

Nine lifelike dragons are carved on the stone gate, with their fangs bared and claws swaying, exuding a suffocating aura of oppression.

"Where is this..." Shi Hao felt an unprecedented sense of oppression, as if a mountain was pressing on his heart, making it hard for him to breathe.

"The Netherworld Cult Master's secret training room!" Shi Yi said in a deep voice. He stretched out his hand and pressed on the stone door. A powerful force came from the stone door, pushing him back several steps.

"Let me do it!" Shi Hao stepped forward and released the power of the Supreme Bone without reservation. The golden light turned into a huge palm and slammed hard on the stone gate.

The stone door burst open, and a cold breath rushed in. An old man in a black robe and with a haggard face was seen sitting cross-legged in the center of the secret room. His eyes were closed and black air was around him, as if he came from the devil of the Nine Nether Hell.

"Are you the leader of the Netherworld?" Shi Yi and Shi Hao stepped forward at the same time, staring at the old man in black robes fiercely.

The black-robed old man slowly opened his eyes, revealing a pair of blood-red pupils. A sinister smile played on the corners of his mouth. "Two brats, still wet behind the ears, dared to trespass into my secret training room. You really don't know how to live or die!"

"Today is the day you die!" Shi Yi and Shi Hao exchanged glances and attacked simultaneously, unleashing the power of their double pupils and supreme bones without reservation. The power transformed into two streams of light, shooting towards the black-robed old man...

"You're overestimating your own abilities!" The black-robed old man snorted coldly, quickly forming seals with his hands. A terrifying aura erupted from his body, and the entire secret room shook violently, as if it would collapse at any moment...

The Netherworld Cult Leader laughed wildly, slamming his withered palm to the ground. A suffocating pressure instantly enveloped the entire chamber. "Arrogant boy, today I will show you what true power is!"

Black mist gushed from his body, transforming into countless demonic spirits with bared fangs and claws, roaring and charging towards Shi Yi and Shi Hao. Shi Hao's body was ablaze with golden light, and the power of the Supreme Bone condensed into a golden long sword in his hand. Wherever the blade flashed, the demons were scattered. Shi Yi's body was as fast as lightning, shuttling between the ghosts. His double pupils shot out two sharp beams of light, shattering the demons one by one.

“A mere trifle!” The Netherworld Cult Leader roared, forming seals with his hands. Black mist gathered above his head, forming a massive skull, emitting a terrifying aura of death. The skull opened its massive mouth, spewing out a black beam of light that headed straight for Shi Hao.

Shi Hao didn't dare to delay. He gripped his long sword tightly with both hands, and with a burst of golden light, he slashed at the black light column. "Bang!" With a loud bang, the light column was split in half, but the powerful impact still knocked Shi Hao back several steps.

"Brother, be careful!" Shi Yi noticed that when the Nether Lord launched his attack, the black mist around him became thinner. He immediately realized that this might be the Nether Lord's weakness!

"Shi Hao, attack the black fog around him!" Shi Yi shouted, his pupils shone brightly, his body turned into a flash of lightning, circled behind the Nether Lord, and with both palms out, two beams of light containing powerful power bombarded the black fog around the Nether Lord.

Shi Hao understood what he meant, and poured the power of the Supreme Bone into the long sword without reservation. The golden blade light turned into a roaring dragon, breaking through numerous ghost shadows and going straight for the Lord of the Netherworld!

"Ah!" The Netherworld Cult Leader let out a shrill scream, and the black mist rolled violently, as if it were burned by a raging fire. He never expected that these two young men could actually find his weakness and cooperate so tacitly!

"Not good!" The Netherworld Cult Leader's expression changed drastically, a fierce look flashing in his eyes. "Since you're seeking death, then let's do it together..." He suddenly raised his right hand, and a black disc appeared in his palm. The disc was engraved with strange runes, emitting a terrifying aura...

"...Let us die here together!" The Netherworld Cult Leader, seemingly mad, his hoarse voice echoing throughout the empty hall. A blinding light erupted from the black disc, and the entire castle began to tremble violently. Cracks appeared on the walls, as if they would collapse at any moment.

Shi Yi and Shi Hao's expressions suddenly changed. They felt the threat of death. This power was far beyond their imagination!

"Oh no! He's going to self-destruct!" Taoist Xuanfeng, who had been paying close attention to the battle situation, exclaimed, and with a flash of his body, he was about to rush forward to stop the Netherworld Sect Leader.

"Hahaha, it's too late! You all must die!" The leader of the Netherworld laughed wildly, and the light of the black disc became brighter and brighter. The whole castle seemed to have turned into a volcano that was about to erupt, filled with the breath of destruction.

However, at this critical moment, Shi Yi suddenly felt a sharp burning sensation in his pupils. He subconsciously closed his eyes, and when he opened them again, the scene before him had changed drastically!

The entire world became transparent before his eyes, countless fine lines interwoven into a mysterious and complex pattern. He saw the structure of the castle, the violent energy flowing within the Netherworld Cultist's body, and also... the core of the black disc!

"Shi Hao! Attack the center of the disc, that's the eye of the formation!" Shi Yi roared, his pupils shone brightly, and two beams of light shot towards the black disc in the hands of the Netherworld Leader like sharp swords.

Although Shi Hao didn't understand what was happening, he had absolute trust in Shi Yi. Without hesitation, he pushed the power of the Supreme Bone to its limit. The golden sword transformed into a dazzling light and struck the center of the black disc with the force of thunder!

When the Netherworld Sect Leader saw this, a trace of fear flashed in his eyes. He never expected that these two young men could find a solution in such a short time!

"No! This is impossible!" The Nether Lord roared, trying to stop Shi Hao's attack, but it was already too late...

Shi Yi's gaze was fixed on the black disc, and the corners of his mouth rose slightly, forming a cold arc.
