Rise of the Otherworld.

Lin Yu wasn't intimidated by the threatening letter; instead, he became even more resolute in his determination to uncover the traitor. His resolute face was now filled with determination, like an unshakable mountain. In the dimly lit study, he reorganized all the clues he had so far and decided to start with the missing supplies. The dim candlelight flickered across his face, illuminating his furrowed brow and determined gaze.

He summoned several disciples in charge of finances and inquired in detail about the records and distribution procedures for the supplies. The atmosphere in the study was tense and oppressive. Several disciples stood trembling with fear, their foreheads covered with sweat. One of the disciples recalled that the person in charge of this batch of supplies was a usually inconspicuous deacon.

"The deacon's name is Zhao Kun. He is usually taciturn, but he does things in a proper manner." The disciple said, his voice trembling slightly, as if he was worried that his answer would bring about some bad consequences. His eyes glanced at Lin Yu from time to time, observing the headmaster's expression.

Lin Yu narrowed his eyes slightly, his eyes revealing thought: "Zhao Kun? I seem to have some impression of this person, but not a deep impression." His fingers tapped lightly on the table, making a rhythmic "knock knock" sound.

Lin Yu immediately sent people to investigate Zhao Kun's whereabouts and background. Like ghosts in the dark night, the disciples moved silently. They shuttled through every corner of the sect, questioning those who had contact with Zhao Kun, not missing any subtle clues.

Meanwhile, Zhang Hao, while discussing his experiences with his disciples, unexpectedly learned that Zhao Kun had previously met with a mysterious individual in a teahouse at the foot of the mountain. It was a secluded teahouse, usually sparsely populated. The worn tables and chairs and creaky walls bore witness to this mysterious encounter.

"At the time, I just thought it was a little strange and didn't think much of it. Now that I think about it, that mysterious man's figure and attire don't seem like someone from our sect." The disciple who provided the clue tried to recall the scene, his face full of regret. He kept grabbing at the corner of his clothes, as if this would make his memory clearer.

Zhang Hao patted him on the shoulder: "It's not your fault. It's very helpful for us that you can remember these things now." His eyes were full of encouragement, trying to ease the disciple's tension.

While reviewing the sect's records, Li Yue also discovered something unusual about Zhao Kun. His family seemed to have intricate ties to a hostile faction. Those obscure records and vague clues, like pieces of a puzzle, gradually pieced together a disturbing truth. Li Yue's eyes were focused and persistent, not missing a single possible detail.

All the clues pointed to Zhao Kun, and Lin Yu decided to secretly monitor him. The disciples in charge of monitoring him stood firm day and night, not daring to slack off even for a moment. They hid in the dark, their eyes closely watching Zhao Kun's every move. Even the slightest movement would alert them.

However, Zhao Kun seemed to have noticed something and became more cautious. He no longer followed his usual schedule, and his whereabouts became increasingly erratic. Sometimes he would return home late at night, and sometimes he would leave early, leaving people confused.

One night, the moonlight shone like water, casting a silvery glow on the buildings of Xuantian Gate. Lin Yu, however, had no time to admire the tranquil night scene. He discovered that Zhao Kun had quietly sneaked into the Sutra Library. The moonlight shone on the roof of the Sutra Library, reflecting Zhao Kun's sneaky figure.

"Finally, the truth is revealed." Lin Yu thought to himself. His heartbeat accelerated slightly, and he was both excited and nervous. But he knew that he had to remain calm at this moment and not alert the enemy.

He led his trusted disciples to quietly surround the Sutra Library. Everyone held their breath, their footsteps as light as falling leaves. Their figures loomed in the moonlight, like hunters in the dark night, waiting for the perfect opportunity.

Inside the Sutra Library, Zhao Kun was anxiously searching among the bookshelves, beads of sweat dripping down his forehead. His eyes were panicked, and his hands were shaking.

"Zhao Kun, don't even think about escaping today!" Lin Yu shouted angrily, breaking the silence. The sound echoed in the Sutra Library, shaking the books on the bookshelf slightly.

Zhao Kun's body trembled, and his face turned pale as paper in an instant. He turned his head in horror and looked at Lin Yu and his disciples, his eyes filled with despair and fear.
