Rise of the Otherworld.

Lin Yu and the disciples who retreated back to the sect were all panting and exhausted. Everyone's face was filled with tension and worry. Many people had shocking wounds on their bodies, and blood stained their clothes red. The atmosphere was solemn and depressing, as if a heavy stone was pressing on everyone's heart.

Lin Yu frowned, his furrowed brows like two deep ravines, his eyes full of deep worry, and he said in a low and heavy voice: "The enemy is coming with great force and ruthless means this time. I'm afraid they won't give up. In the days to come, Xuantianmen will face even more severe tests."

The mysterious man's expression was stern, like a piece of cold iron. His eyes were firm and deep. He spoke slowly, "They will certainly make further moves and will not stop until they achieve their goal. We must be fully prepared to deal with the coming storm."

Lin Yu nodded, his eyes swept over the injured disciples, his eyes full of pity and determination, he turned to the disciples and said: "Everyone go to heal your wounds and rest first, don't let your injuries affect the subsequent battles. Regain your strength, and then we will discuss a countermeasure together."

Upon hearing this, the disciples dispersed, some supporting each other, while others staggered alone towards their respective residences. Lin Yu and the mysterious man did not dare to stop for a moment and came to the meeting hall without stopping.

The atmosphere in the meeting hall was dull. Lin Yu had a worried look on his face, as if troubled by endless worries. He looked at the mysterious man, his voice filled with helplessness and anxiety: "Senior, the situation is extremely unfavorable to us now. Xuantian Sect is in danger. As the head of the sect, I feel powerless and don't know what to do?"

The mysterious man remained silent, with his hands behind his back, pacing back and forth in the hall. After a long time, he stopped and looked at Lin Yu with a firm gaze. After thinking for a moment, he said: "The most urgent task is to improve the strength of the disciples and enhance our own combat effectiveness. At the same time, strengthen the sect's fortifications to prevent the enemy from attacking again."

Lin Yu agreed deeply and nodded repeatedly, but then he looked embarrassed: "It's just that this requires a lot of time and resources. We are currently short of resources and time is running out. I'm afraid it will be difficult to achieve the goal in a short time."

The mysterious man's gaze was as firm as iron, as if nothing could shake his resolve. He spoke in a resounding voice, "Everything depends on our own efforts. As long as we work together and unite as one, we will surely overcome this disaster. Even if there are mountains of swords and seas of fire ahead, we will not fear."

Over the next few days, Xuantian Sect was a scene of bustle. Disciples cast aside distractions and devoted themselves to their training. The martial arts training grounds shone with sword energy and roaring cheers. In the alchemy room, furnaces burned day and night, thick smoke billowing as alchemists sweated profusely as they meticulously refined various elixirs. Craftsmen also diligently reinforced the defenses, the clanking sound of hammering echoing throughout the sect.

Lin Yu personally oversaw all matters, remaining incredibly busy. He shuttled between locations, sometimes cheering on his disciples, sometimes discussing improvements to the fortifications with the craftsmen. A mysterious figure would occasionally appear among the disciples, guiding them and imparting exquisite techniques and skills. His insightful explanations were profound, enlightening the disciples and boosting their skills.

With everyone's concerted efforts, Xuantian Sect gradually began to thrive. The disciples' strength improved significantly, their swordsmanship became more sophisticated, and their magic became more refined. Their fortifications also became stronger, with the walls covered in various traps and traps, making them a formidable sight.

However, just when they thought they could breathe a sigh of relief, a spy came running in with a panicked report: "Master, it's bad! The mysterious organization's army is approaching again, a dark mass with no end in sight."
