Rise of the Otherworld.

The group of men in black pressed forward step by step. They exuded a cold aura, as if coming from the abyss of the underworld, which made Lin Yu and others' nerves, which had just relaxed, tense up again. Everyone's heartbeat accelerated rapidly, and their breathing became rapid.

Lin Yu gripped the sword tightly in his hand and shouted angrily: "If you dare to take another step forward, don't blame me for being ruthless!" His voice echoed in the air, with endless anger and majesty. His eyes were like burning flames, full of desire to fight and unyielding will.

The men in black remained unmoved and continued to approach slowly and steadily. Their footsteps were in perfect unison, like a well-trained army. Every step carried an invisible pressure that made Lin Yu and the others feel breathless.

Xiaoyaozi frowned and whispered, "Master, these people are not here with good intentions, we must be careful." His voice was full of worry and vigilance, and the magic weapon in his hand was unconsciously clenched.

Lin Yu nodded slightly, his eyes fixed on the man in black. His brain was working rapidly, thinking about how to deal with it.

Suddenly, a man in black took the lead in attacking. He flashed in front of a disciple and raised his hand to strike him. His speed was as fast as a ghost, leaving no time for reaction.

The disciple had no time to react and was sent flying, falling heavily to the ground, spitting blood. His face instantly turned as pale as paper, and he groaned in pain.

"Damn it!" Lin Yu was furious and swung his sword towards the man in black. His movements were swift and fierce, and the sword drew a silver arc in the air, accompanied by a whistling sound.

The man in black dodged sideways and threw a backhand punch, which collided with Lin Yu's sword with a dull sound. The powerful impact made Lin Yu's arm numb, but he still held the hilt tightly and refused to retreat.

Other men in black joined the fray, and for a moment the scene descended into chaos. Swords gleamed and shadows clashed, while shouts and the sounds of fighting intertwined.

Lin Yu and his companions fought hard, but the black-clad men were all exceptionally skilled and coordinated. Their moves were tricky and strange, making it difficult to defend against them. Lin Yu's side gradually lost the upper hand, and the wounds on his disciples became more and more, and their clothes were stained with blood.

"Everyone, calm down and hold your ground!" Lin Yu shouted loudly. His voice was particularly clear in the chaos, trying to stabilize the morale of the troops.

However, the situation became increasingly unfavorable for them, and several more disciples were injured and fell to the ground. Their groans and cries for help pierced Lin Yu's heart.

At this moment, Lin Yu discovered that the attacks of the men in black seemed to have some pattern. They always attacked from one side first, and then quickly moved to the other side, trying to disrupt the defense of Lin Yu and others.

While fending off the attacks, he observed the movements of the man in black and gradually came up with a plan.

"Follow my instructions! Disciples on the left, defend, disciples on the right, attack!" Lin Yu shouted. His voice was decisive and firm, full of the majesty of a commander.

Hearing this, everyone followed Lin Yu's command. Their movements began to become orderly, no longer as chaotic as before.

After a difficult battle, they finally gradually turned the situation around. Lin Yu's sword stabbed the man in black again and again, and the disciples' attacks began to work.

But just when they thought they were about to defeat the men in black, they suddenly retreated and disappeared without a trace, just as mysteriously as they had appeared, leaving no trace.

"What on earth is going on?" a disciple asked, panting heavily. His face was covered in a mixture of sweat and blood, and his eyes were filled with confusion and fatigue.

Lin Yu looked at the direction where the men in black disappeared, his heart full of doubts. Who were these men in black? Why did they suddenly attack them? Why did they suddenly retreat?

Before they could figure it out, another round of shouting came from the distance. The shouting was full of anxiety and fear, which made people's hearts hang in the air again.

Lin Yu and the others looked at each other, then walked towards the direction of the shouting. What would be waiting for them?
