Rise of the Otherworld.

Lin Yu and Lin Xiaotian began to investigate the origins of the men in black. They first questioned the injured disciples, but the disciples knew nothing about the identities of the men in black, only that they suddenly appeared and launched an attack.

Lin Yu decided to send some disciples to the nearby towns to inquire about the news and see if there were any clues about the man in black. At the same time, he also asked some elders to strengthen the defense of the sect to prevent the man in black from attacking again.

A few days passed, and the disciples who had been sent out returned to the sect one after another, but they did not bring much useful information. However, one disciple heard some rumors in a small town about a mysterious organization operating in secret. The members of this organization all wore black clothes and masks on their faces.

After hearing the news, Lin Yu and Lin Xiaotian decided to go to the town to investigate. After they arrived, they asked around for information about the mysterious organization. After some effort, they finally found someone who knew something about the situation.

This person told them that this mysterious organization had existed for a long time. Their purpose was unknown, but they were said to be looking for some powerful treasures. Lin Yu's heart moved, and he remembered the gem he got from the temple. Could it be that the man in black came for that gem?

Lin Yu and Lin Xiaotian decided to continue their investigation. They wanted to find the headquarters of this mysterious organization and uncover their true identity. During the investigation, they encountered some difficulties, but with their wisdom and strength, they finally found some clues.

They discovered that the headquarters of this mysterious organization was located in a remote valley. Lin Yu and Lin Xiaotian quietly sneaked into the valley and found that there were many men in black patrolling here, and there were also some strange buildings in the valley.

Lin Yu and Lin Xiaotian carefully avoided the patrolling men in black and approached one of the buildings. They looked inside through the window and saw some men in black studying some mysterious objects.

"What are these people doing?" Lin Xiaotian asked in a low voice.

Lin Yu frowned and said, "They may be studying some evil spells."

At this moment, a man in black suddenly discovered them and shouted, "There are outsiders breaking in!"

Lin Yu and Lin Xiaotian were startled. They knew they had been discovered, so they turned and ran away immediately. The men in black chased them, and while they were running away, Lin Yu and Lin Xiaotian started a fierce battle with the men in black.

During the battle, Lin Yu and Lin Xiaotian found that the strength of these men in black was very strong, and they were gradually at a disadvantage. At this moment, Lin Yu suddenly thought of the gem, and he decided to use the gem to deal with these men in black.

Lin Yu took out the gem, used his strength, and stimulated the power in the gem. The gem emitted a dazzling light, illuminating the entire valley. The men in black were enveloped by the light and immediately let out a cry of pain.

Lin Yu and Lin Xiaotian took the opportunity to escape the pursuit of the men in black and escaped from the valley. After returning to the Zhenwang Sect, they told the elders what they had found. The elders were shocked.

"This mysterious organization is actually researching evil spells. We must stop them as soon as possible!" said an elder.

Lin Yu nodded and said, "That's right, we can't let them succeed."

So, Lin Yu and the elders began to make plans and prepare to attack the mysterious organization. They wanted to completely destroy the organization and protect the peace of the continent.
