After leaving Bai Ling's castle, Lin Yu and Su Yao followed Bai Ling's instructions and headed towards the Ghost Valley. Along the way, they were cautious and always alert to the dangers around them. After several days of trekking, they finally came to the entrance of the Ghost Valley. There was a thick fog here, making it difficult to see the road ahead. The occasional strange sounds made people feel uneasy. Lin Yu said, "This is the Ghost Valley, we have to be careful." Su Yao nodded and said, "This place looks very dangerous, we must be extra careful." They walked into the Ghost Valley carefully, the fog became thicker and thicker, and the vision became more and more blurred. They could only rely on each other's voices and feelings to move forward. After walking for a while, they suddenly heard a fierce fight. Lin Yu and Su Yao's hearts tightened, and they quietly walked in the direction of the fight. When they approached, they found a group of people fighting fiercely. One side was some people wearing black clothes, and the other side was some people wearing white clothes. The two sides fought hard and the scene was very intense. Lin Yu and Su Yao hid aside and observed the battle. They found that these people seemed to have very high martial arts skills, and their fighting methods were also very strange. Just as they were observing, a man in black suddenly discovered them. The man in black shouted at them: "Who are you? Why are you here?" Lin Yu and Su Yao's hearts tightened, and they knew they were discovered. Lin Yu said: "We are just passing by here and don't want to participate in your fight." The man in black sneered and said: "Since you have seen our fight, don't think about leaving alive." As he said, he rushed towards Lin Yu and Su Yao. Lin Yu and Su Yao hurriedly drew their weapons and prepared to fight. Just as they were preparing to fight, a man in white suddenly appeared and blocked the attack of the man in black. The man in white looked at Lin Yu and Su Yao and said: "You guys go quickly, this is not the place you should come." Lin Yu and Su Yao hesitated for a moment. They didn't know whether the man in white was an enemy or a friend. But they also knew that now was not the time to hesitate, and they had to leave here as soon as possible. They nodded to the man in white, then turned and left. They searched for clues everywhere in the Ghost Valley, but they never found anything useful. Just when they were disappointed, Su Yao suddenly received a letter from home. The letter was sent by her family, saying that some major things had happened in the family and she needed to go back as soon as possible. Su Yao looked at the letter, her heart full of worry. She knew that the family's affairs must be serious, otherwise her family would not be so anxious to let her go back. Lin Yu looked at Su Yao and said, "You go back first, family affairs are important. I will continue to look for clues alone." Su Yao hesitated and said, "But it's too dangerous for you to go alone." Lin Yu said, "It's okay, I will be careful. You can go back with peace of mind. After you finish dealing with family affairs, we will look for clues together." Su Yao nodded and said, "Okay, then you must be careful. I will come to you after I finish dealing with family affairs." After Su Yao left, Lin Yu continued to look for clues in the Ghost Valley. He explored everywhere, hoping to find some clues about the mysterious organization. However, Ghost Valley was full of dangers and mysteries, and Lin Yu never found any useful clues. He began to feel a little frustrated, but he knew that he could not give up. Just as Lin Yu was about to leave Ghost Valley, he suddenly met a mysterious old man. The old man was wearing a gray robe, with gray hair and a kind face. The old man looked at Lin Yu and said, "Young man, why are you here?" Lin Yu looked at the old man and became alert. He said, "Old man, I'm looking for clues to a mysterious organization. Do you know this mysterious organization?" The old man was slightly startled and said, "Mysterious organization? Why are you looking for this mysterious organization?" Lin Yu said, "My parents were killed by people from this mysterious organization. I must find them and avenge my parents." The old man looked at Lin Yu's determined 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, I can tell you something about this mysterious organization." Lin Yu was delighted and said hurriedly, "Old man, tell me quickly." The old man said, "This mysterious organization is very powerful. Their goal is to rule the entire Yunze Continent. They are secretly planning a huge conspiracy. Once the conspiracy succeeds, the entire Yunze Continent will fall into chaos." Lin Yu was shocked. He didn't expect the purpose of this mysterious organization to be so great. He hurriedly asked: "Old man, do you know where this mysterious organization is?" The old man shook his head and said: "I don't know where this mysterious organization is, but I know some of their patterns of action. They usually appear in some mysterious places, and their actions are very secretive. Few people know their true purpose." Lin Yu said: "Old man, thank you for telling me this. I will definitely find this mysterious organization and avenge my parents." The old man looked at Lin Yu and said: "Young man, you have to be careful. This mysterious organization is very dangerous, and it is difficult for you to deal with them alone. You can find some like-minded people to fight against this mysterious organization together." Lin Yu nodded and said, "I see. Old man, do you have anything else to tell me?" The old man thought for a while and said, "There is one more thing you need to pay attention to. There is a very powerful person in this mysterious organization. He is very skilled in martial arts and cruel. If you meet him, you must be careful." Lin Yu said, "I will be careful. Old man, do you know who this person is?" The old man shook his head and said, "I don't know who this person is, but I heard that he is called the 'Shadow King'. He is one of the core figures of the mysterious organization and is very dangerous." Lin Yu remembered the name. He knew that he must be careful of this "Shadow King" in the process of searching for the mysterious organization. After the old man finished these words, he turned and left. Lin Yu looked at the old man's back as he left, and his heart was full of gratitude. He knew that the old man's words were very helpful to him. Lin Yu decided to leave Ghost Valley first and then look for other clues. After he left Ghost Valley, he began to ask around about the mysterious organization. At the same time, Su Yao also returned to the family. She found that some major things had indeed happened in the family. It turned out that some people in the family colluded with external forces in an attempt to seize control of the family. Su Yao's family hoped that she could help the family through this difficult time. Su Yao agreed without hesitation, and she decided to use her own strength to protect the family. Su Yao began to investigate the traitors in the family, and she found that these traitors were connected to a mysterious force. This mysterious force also seemed to be related to the mysterious organization. Su Yao was shocked, and she realized that the family's affairs might be related to the mysterious organization that Lin Yu was looking for. She decided to solve the family's problems as soon as possible, and then go to find Lin Yu to continue looking for clues to the mysterious organization together.
