After leaving the inn, Lin Yu and Su Yao rushed to the place where Lin Yu's parents were killed. Along the way, both of them remained vigilant to prevent the people of the Black Wind Hall from attacking again. After a long journey, they finally came to the place that filled Lin Yu with painful memories. This is a desolate valley, surrounded by silence, with only occasional bird calls. Lin Yu's eyes were full of sadness and anger. He walked slowly into the valley, as if he saw that terrible night again. Su Yao followed Lin Yu silently, she could feel the pain in Lin Yu's heart. She gently held Lin Yu's hand, giving him strength and comfort. Lin Yu looked at Su Yao gratefully, and the pain in his heart was slightly relieved. They began to look for clues carefully. The valley was overgrown with weeds, and there were still some traces of fighting on the ground. Lin Yu squatted down and carefully observed these traces, hoping to find some useful information from them. Su Yao was looking for items that might be left around. After some efforts, they finally found some clues. Under a stone, they found a broken jade pendant. There was a strange pattern engraved on the jade pendant. Lin Yu felt that the pattern was somewhat familiar, but he couldn't remember where he had seen it. Su Yao looked at the jade pendant and said, "This jade pendant may be a clue left by your parents. We can take it to ask others, maybe someone recognizes this pattern." Lin Yu nodded and carefully put the jade pendant away. They decided to go back to Canglan City first to see if they could find someone who knew this jade pendant. On the way back to Canglan City, they met a strange old man. The old man was wearing a gray robe, with gray hair and a kind face. He stopped Lin Yu and Su Yao and said, "Young man, I see that you have an unusual breath. Are you looking for something?" Lin Yu and Su Yao looked at each other and became alert. Lin Yu said, "Old man, why do you say that? We are just passing by here." The old man smiled and said, "Young man, don't be nervous. I have no ill intentions. I just feel that you have a strong obsession, so I asked this question." Lin Yu hesitated and said, "To be honest, we are indeed looking for some clues. Old man, do you know this pattern?" As he said that, Lin Yu took out the jade pendant and showed it to the old man. The old man took the jade pendant, observed it carefully for a while, and his face suddenly became solemn. He said, "I have seen this pattern. It is the symbol of a mysterious organization. This organization is very powerful and acts secretly. Few people know of their existence." Lin Yu and Su Yao were shocked. They did not expect that this jade pendant would lead to a mysterious organization. Lin Yu hurriedly asked: "Old man, do you know what this organization is called? Where are they?" The old man shook his head and said: "I don't know the name of this organization, nor do I know where they are. I just saw this pattern by chance, so I remember it. However, I can tell you that this organization is very dangerous, and you'd better not provoke them." Lin Yu said: "Old man, my parents were killed by people from this organization. I must find them and avenge my parents." The old man looked at Lin Yu's firm eyes, sighed, and said: "Young man, your courage is commendable, but the road to revenge is full of dangers. You must be mentally prepared." Lin Yu said: "I'm not afraid. As long as I can avenge my parents, I'm willing to do anything." The old man nodded and said: "Okay, since you have decided, I won't stop you. However, you must remember to be cautious in everything and don't act impulsively." After that, the old man returned the jade pendant to Lin Yu and turned away. Lin Yu and Su Yao looked at the old man's back as he left, full of doubts. Who is this old man? Why does he know this pattern? How credible is his words? They decided to return to Canglan City first and then make plans. After returning to Canglan City, they began to ask around about the mysterious organization. However, most people did not know the existence of this organization, and only some old people had heard some rumors. It is said that this mysterious organization has existed for a long time, their purpose is unknown, but their means are very cruel. They often act in secret, and few people have seen their true faces. Lin Yu and Su Yao were very disappointed. They thought they could find some clues in Canglan City, but they found nothing. Just when they were about to give up, a mysterious man appeared. This man was covered in a black cloak and his face could not be seen clearly. He stopped Lin Yu and Su Yao and said, "Are you looking for that mysterious organization?" Lin Yu and Su Yao's hearts tightened and looked at this person vigilantly. Lin Yu said, "Who are you? How do you know we are looking for that mysterious organization?" The mysterious man said, "It doesn't matter who I am. What's important is that I can help you find that mysterious organization." Lin Yu and Su Yao looked at each other, full of doubts. They didn't know what this person's purpose was, nor did they know if he was trustworthy. But they didn't want to miss this opportunity, after all, this was their only clue at the moment. The mysterious man seemed to see their doubts and said, "Don't worry, I have no ill intentions. I just want to help you. Because I also have a grudge against that mysterious organization." Lin Yu said, "Why do you want to help us? What are your conditions?" The mysterious man said, "My conditions are very simple. When you find that mysterious organization, I will deal with them with you." Lin Yu and Su Yao thought about it for a while and felt that this condition was acceptable. They decided to trust this mysterious man and see what clues he could bring them. The mysterious man said, "That mysterious organization is very mysterious, and few people know their whereabouts. However, I know a place where there may be clues about them." Lin Yu and Su Yao hurriedly asked, "Where?" The mysterious man said, "There is an ancient temple on the outskirts of Canglan City. It is said that it was once the location of a mysterious sect. This sect has had some contact with that mysterious organization, and perhaps some clues can be found there." Lin Yu and Su Yao decided to go to the temple to have a look. They followed the mysterious man to the outskirts of Canglan City. There was no one here, only a dilapidated temple stood there alone. The door of the temple was closed, covered with dust and cobwebs. Lin Yu and Su Yao carefully pushed the door open and walked in. The temple was dark and damp, filled with an old smell. They looked around for clues, but found nothing useful. Just when they were disappointed, the mysterious man suddenly said: "Look, there is an entrance to the basement." Lin Yu and Su Yao looked in the direction pointed by the mysterious man, and indeed found an entrance to the basement. They walked down to the basement carefully, and it was pitch black inside. They lit torches and continued to move forward. There was a mysterious atmosphere in the basement, and the walls were engraved with strange patterns and words. Lin Yu and Su Yao carefully observed these patterns and words, hoping to find some clues from them. After some effort, they finally found some useful information. On one wall, they found a map with a mysterious place marked on it. There were also some text descriptions next to it, which seemed to be some secrets about the mysterious organization. Lin Yu and Su Yao were very excited. They finally found some clues. They decided to follow the instructions on the map and go to the mysterious place to have a look.
