Rise of the Otherworld.

Lin Yu and his disciples engaged in a desperate struggle with the reinforcements of the Shadow Gate in the secret room, and the situation became increasingly critical. Swords flashed and shadows clashed, and every moment was filled with the threat of life and death.

Lin Yu was wounded in many places, and his clothes were stained with blood. His once handsome face now looked a little haggard, but his eyes were still firm and revealed an unyielding light. "Brothers, hold on!" He shouted loudly, with a hint of fatigue in his voice, but still full of strength, inspiring everyone's fighting spirit.

A disciple fell beside Lin Yu, his eyes gradually losing their luster. It was the regret for not wanting to give up life and the regret for the unfinished mission. "Brother!" The other disciples were filled with grief and anger, tears welling up in their eyes, but they could only suppress their grief and continue fighting, turning the anger in their hearts into the power to kill the enemy.

Just when everyone was feeling desperate, the system suddenly sent a prompt: "Host, a secret passage mechanism has been found in the secret room, which leads to a safe place." This sudden news was like a ray of light in the darkness, and a new strength instantly surged in Lin Yu's tired body.

Lin Yu quickly looked around and finally found a unique stone wall in a corner. There were some obscure runes engraved on the stone wall. If it weren't for the system's prompt, it would be extremely difficult to find. "Follow me!" He shouted loudly, his voice full of urgency and hope, and rushed towards the stone wall first.

The enemies of the Shadow Gate sensed their intentions and intensified their attacks, their moves becoming increasingly ferocious. "We must not let them escape!" The enemy's roar echoed in the secret room.

Lin Yu fought hard to resist the enemy's attack. The long sword in his hand was like a dragon emerging from the sea, and every swing was full of determination. His wounds continued to bleed due to the violent movements, but he seemed to feel no pain. "Quick, open the mechanism!" He shouted while resisting the enemy.

A disciple frantically groped the stone wall, his hands trembling as he searched for the mechanism's trigger. Sweat dripped from his forehead, his eyes filled with tension and anticipation.

Finally, thanks to the disciples' unremitting efforts, accompanied by a low roar, the stone wall slowly opened, revealing a dark passage. The passage was filled with a damp smell, which made people feel a sense of unknown fear.

"Let's go!" Lin Yu covered the disciples as they entered the passage. His eyes were firm and resolute, as if he wanted to use his body to build a final line of defense for the disciples.

However, just as the last disciple entered the passage, enemies from the Shadow Gate rushed over, trying to prevent them from escaping.

Lin Yu used all his strength to repel the enemy, and he also entered the passage and quickly pressed the mechanism to close the entrance of the passage. The moment the stone wall closed, the enemy's attack was blocked outside, leaving only a burst of angry roars and collisions.

They ran desperately through the passage, the ground beneath their feet damp and rough, their breathing rapid and heavy. The constant sounds of the Shadow Gate enemies trying to open the traps behind them, like a death-beating drum, made them dare not pause for even a moment.

After an indeterminate amount of time, they finally reached the end of the passage. Before them lay a forest, sunlight filtering through the leaves, creating dappled shadows. The refreshing air washed over them, relaxing their tense nerves.

"We are safe for now." Lin Yu breathed a sigh of relief and collapsed to the ground. His body had reached its limit, every muscle was trembling, and every breath was accompanied by pain.

The disciples also sat down to rest, each of them exhausted. Their clothes were tattered, their bodies covered with wounds and blood, but their eyes showed a hint of relief at having survived.

"Master, what should we do next?" asked a disciple, his voice weak and confused.

Lin Yu gritted his teeth and stood up. "We must return to the True King Sect as soon as possible, tell everyone the secrets found in the secret room, and re-formulate the battle plan." He looked in the direction of the True King Sect with determination.

In this life-or-death dilemma, can they successfully return to the True King Sect, and can they use the secrets they discover to turn the tide of the war? The future is full of unknowns and challenges.
