Lin Wu pondered the meaning of her words and said slowly: "They took the initiative to ask me to cooperate, and I think it's okay. It just so happened that a friend of mine was accidentally implicated by the archaeological team and something happened here. I wanted to find out what happened, so I agreed."

"They lied to you!" Gu Siyin tightly grasped Lin Wu's hand. "With your face, anyone who sees you will most likely think you are from the Gu family. What's more, my sister and second brother are working for them. They are so familiar with us, they must know that you are from the Gu family!"

Gu Siyin was overthinking this.

The relationship between Lin Wu and the Gu family was not leaked.

Earlier, Lin Wu had asked people to carefully nibble out any signs of the problem to prevent others from noticing anything unusual.

Furthermore, it was possible that Chi Yangzhi had lost a child eighteen years ago, which was not a secret among the noble families in Beijing, but outsiders would never have thought that the child had survived. At least when Lin Wu first met Chi Yangzhi, he did not think about it, and even less did Old Xun.

It can be seen that even if outsiders are a little hesitant about the similar appearance, they will only be surprised by the appearance and will not think that she and the Gu family are from the same family.

Lin Wu thought that the reason why the Gu family could feel that they were related to her at first glance was probably because of blood ties.

Gu Siyin continued, "Wuwu, you are still young and have not seen much. You don't understand how hateful those two old guys are!"

Lin Wu: “Hmm…”

Gu Siyin gritted her teeth and said angrily, "They definitely deliberately tricked you into cooperating. They want to win over all the Gu family members. If it weren't for the inconvenience of my eldest brother's status and the requests made by my second brother when he first entered, they would not have touched other Gu family members. They would have dragged my eldest brother into the water long ago!"

"But do you think they've given up? No. They took advantage of my second brother being abroad and tricked my sister into going in. By the time my sister realized what was happening, it was already too late. I didn't expect them to still be so evil. You just came home, and they're targeting you again!"

Lin Wu was confused: "Why are they so obsessed with Gu's family?"

"Because the Gu family members have a special physique, they can wear what they want for a long time without any problems..." Gu Siyin said as she touched her neck, but found nothing and she paused.

Lin Wu seemed to realize something, and took out the other person's pendant from his pocket and said, "Are you talking about this meteorite pendant?"

Gu Siyin took a look and said, "Yes! It won't be a problem for us Gu family members to wear it. Ordinary people can only wear it for a short while. If they wear it for a long time, their bodies will be damaged by the radiation, and in serious cases, they may even die..."

Gu Siyin was just about to check if the pendant was damaged when she suddenly realized an important point.

She immediately looked up and asked, "How do you know this is made of meteorite?"

Lin Wu's mind relaxed. It seemed that she could learn some questions about the archaeological team from Gu Siyin.

"I am……"

"Han Yuesong and Gao Zhouwen, those two old bastards told you, right!" Gu Siyin raised her voice.

Lin Wu paused, "...I guess so. I found out there is a meteorite here, and they came here for that too, but they refused to say more, only saying they would talk about it later."

"This is their usual trick. They first draw your curiosity and then make you fall into their trap without knowing it!"

Gu Siyin said firmly, cursing: "These two damned old bastards, it's fine if they included me and my second brother, but now they are even planning to target you! They'd better die here, otherwise I will kill them when I get out! No, let them die here and report that they died in the line of duty!"

Lin Wu: "...They seem to be your superiors."

Gu Siyin said coldly: "From now on, it's not the same anymore. Besides, they are directly leading Team One, what does Team Two have to do with them? If they have any objections, let them complain. As long as they can get rid of me, I respect them as men and I will take their last name!"

Lin Wu: “…”

She seemed to understand why Gu Chengbai and the others were hesitant when they mentioned Gu Siyin.

Lin Wu quickly shook his head and took the opportunity to ask what he wanted to know.

"So you and Han Yuesong are from the same organization, and you came here just for the meteorite?"

"So what organization are you?"

"this……"

Gu Siyin hesitated.

Lin Wu said, "I don't like to get involved in muddy waters, nor do I want to be dragged into disputes. If your organization is similar to a special department, I would consider joining it as a training. If not, I don't want to join at all, lest I feel uneasy..."

"It's No. 49!" Gu Siyin immediately told the whole story, "Wuwu, No. 49 is not a good place, you must not come in. It's enough for the Gu family to have me and my second brother in there."

Lin Wu was really surprised this time, "Are you from No. 49?"

The brand she got before... She finally remembered, it really was the totem of No. 49!

She had taken a look at it before when she was helping Miyano find someone, but Chu Zhongwu and the others told her not to interfere too much in Miyano's affairs, so she didn't take it seriously. She gave the information to Miyano and never looked at it again.

Gu Siyin nodded, thinking that Lin Wu didn't know what No. 49 was, so she explained it to her in detail, and finally said, "No. 49 is directly under the leadership of the Central Committee. There are six teams in total, and each team has only forty people. They are all talents recruited from the five clans in Beijing and the main branches of the five elements in the black market. However, since three years ago, a special laboratory has been established to recruit scientific research talents."

"Wuwu, Unit 49 is extremely dangerous. Every mission is like putting your head on the line. Unit 49 lost a lot of men here this time, which is a good example. So no matter what benefits those two old guys promise you, you must not agree to go in. If they make things difficult for you, you have your second brother and sister to protect you."

Even if it was No. 49, Lin Wu was not interested and did not take it to heart.

She only asked: "Where did No. 49 get the news that there was a meteorite here?"

If Gu Siyin could tell Lin Wu everything before, then this involves confidential information and it is not possible for Lin Wu to know it.

Gu Siyin avoided the question: "Don't worry about it. Wuwu, don't be afraid. Sister will find a way to get you out of here. When the time comes, I will definitely settle the score with them and let you vent your anger..."

Lin Wu asked, "Is it because of the '511' case and the underground city?"

Gu Siyin stopped talking abruptly. She stared at Lin Wu for a moment. Her pupils shrank and she said in a lost voice, "They even told you this?! They... Damn it, these are adults' business. Why would they tell you to do anything?"

At this moment, Gu Siyin's thoughts about Han Yuesong and Gao Zhouwen's rebellion reached their peak.

Lin Wu was silent for a moment, then said honestly, "I found out some of it. Gu Shiqing and the others also know about it."

Lin Wu selectively told Gu Siyin the whole story of the "511" case and the situation in the underground city, including what happened and how Chi Yangzhi was related to it over the years.

Gu Siyin was totally caught off guard and just stood there.

Lin Wu kindly gave her some time to digest the information, and then asked, "They know there is a meteorite here, because they haven't given up investigating the '511' case and have been looking for the underground city?"

Gu Siyin swallowed dazedly, and only reluctantly accepted the shock that Lin Wu knew everything.

But since Lin Wu knew everything, Gu Siyin felt that there was no point in hiding it any longer.

She took a deep breath to calm herself down, sorted out her thoughts, looked at Lin Wu seriously and said, "Yes."

"The losses in the '511' case were huge, so the authorities immediately banned the case and it gradually faded from public view. But a few months later, a black market funeral business was wiped out. This was too big a matter for the authorities to ignore. After some investigation, they heard that the person who was supposed to have died in the '511' case had reappeared. The authorities were very shocked."

"Later, it seemed like the higher-ups received a message from someone and started investigating the '511' case and the underground city again. But this time they kept a low profile and didn't let too many people know. Unit 49 was formed around that time, and they only looked for people from the five tribes at first. Because their families were in trouble, they would be the most motivated and wanted to find their families as soon as possible."

"Not long after, the five elements of the black market also got involved. The first to join were Xuanmen and Shixing. But for some reason, not all of them participated, only some of them, and they kept the news very secret. Moreover, they brought some very useful clues to No. 49, so No. 49 accepted them completely."

Lin Wu suddenly said, "The one who participated in Xuanmen was Cheng Wenwei. What he brought to No. 49 were some special murals from the Blackback Mountain in the northwest, right?"
