"I don't know what he is looking for. After I asked him again and again, he told me part of it. He said that what he was looking for was used in the dungeon and had a special purpose. But if all these things were collected and put together to open it, the blood of a tattooed person would be needed, which is equivalent to a sacrifice and there is only one way to go, and that is death." Guan Chen said in a deep voice.

Lin Wu was suddenly stunned, and couldn't help but think of the underground palace in the Damaya catacombs.

When we found that thing, we used her blood to open it...

"Actually, I also asked Lu Guichi at that time whether he wanted to use you." Guan Chen looked at Lin Wu and said slowly.

Lin Wu's heart sank.

But Guan Chen changed the subject and said, "He was silent for a long time and told me no. He never thought of using you. But that thing has a kind of spontaneity, which will attract people with phoenix tattoos. If Lu Guichi really wants to reorganize it, if you are present at that time, he will not be able to control it at all, nor will he be able to stop it from using your blood. You may also be affected by it and lose consciousness and voluntarily donate blood."

Lin Wu looked stunned and surprised.

"This... are you serious? How could there be such a thing?" Lin Wu didn't quite understand.

Guan Chen said: "My first reaction when I heard it was also incredible. But Lu Guichi's reaction at the time told me that he was not lying to me. He also said that it was because of this that when you were in Danmaya, he kept trying to stop you from going down, but failed."

"He didn't want you to follow him in this time. But he knew he couldn't stop you, so he thought about moving separately from me after we came in, and asked me to stop you and not let you follow him."

As he spoke, a trace of worry appeared on Guan Chen's face.

"But that thing is so dangerous. I'm worried that he might not be able to control it and hurt himself. So I still want to go find him first. It would be best if I could see with my own eyes what that thing is and find out what he is going to use it for."

Hearing this, Lin Wu's expression froze and he asked, "Did he tell you where exactly he was looking for?"

"No." Guan Chen said, "That's why I followed him just now. Otherwise, I might not be able to find him. But he... just froze me. I think he might know that you have the pendant that Gu Shiqing gave you, which can help me regain my mobility, so he did that and didn't turn back."

After Guan Chen finished speaking, he looked at Lin Wu and said, "That's all I know."

In fact, most of what Guan Chen said was beyond Lin Wu's expectations.

As a result, she was in a very complicated mood and didn't know what to say.

After a moment of silence, Lin Wu said, "I have one more thing to ask you."

"What?" Guan Chen said.

Lin Wu said: "Where is the real Lu Guichi?"

Guan Chen was caught off guard and was stunned. After a long silence, he said, "I asked Lu Guichi, and he said that the real Second Young Master Lu... was already dead, before they exchanged identities."

"What is going on?" Lin Wu frowned.

Guan Chen sighed and said, "Lu Guichi said that after he left the underground city, he met a man. He was seriously injured at the time, and that man sent him to the hospital for treatment. It happened to be the same hospital as Lu Ershao. During his hospitalization, he accidentally passed by Lu Ershao's ward and saw him."

"The person who brought him there also noticed the Second Young Master Lu, and found that he was seriously ill and dying, and there was no way to save him. So he proposed a plan to Lu Guichi. Lu Guichi needed an identity outside the underground city, preferably one with power and influence, so that when he grew up, it would be helpful for what he wanted to do in the underground city."

Lin Wu's eyelids jumped. "Are you sure that the real Lu Guichi is dead, and he died of natural causes. There was no... any other tricks?"

Guan Chen looked at Lin Wu solemnly and said, "I believe Lu Guichi will not lie to me in this regard. He has no need to lie to me. I am not his brother Lu Guiyan."

Lin Wu was silent for a moment: "Where is the real body of Lu Guichi?"

"The man who brought him has taken him away and buried him properly."

"Where's the nurse? I heard from Lu Guiyan that there was a nurse there at the time, and they killed another nurse."

"This is true. They didn't expect to be caught, so they killed the caregiver. But they didn't expect there was another caregiver there, so they cleaned up the scene and left. Later they found out it was too late, the caregiver had escaped. Lu Guichi said it took them a long time to find the caregiver, and seeing that he had a family, they couldn't bear to kill him, so they gave him money to buy him off."

Lin Wu didn't quite believe it: "They just let the nurse go like that?"

Guan Chen said calmly: "Black Fox, I know you may not believe me, but... Lu Guichi is really a kind person."

"I believe that he would not kill anyone if he had no other choice. Why would he kill the nurse if he could buy her off with money? And he told me that he had no intention of occupying the identity of Second Young Master Lu forever. When he does what he wants to do, the nurse will return the identity of Second Young Master Lu to him."

"He just didn't expect that his identity would be exposed in advance."

Lin Wu's throat was a little dry, but he stated the facts calmly: "But it's strange that Lu Guiyan found the nurse at that critical moment."

Guan Chen said: "Because Lu Guichi did it on purpose."

Lin Wu was stunned, "...what?"

"At that time, Lu Guiyan already knew that he was not the real Lu Guichi. He said that he felt guilty, so he left clues in advance for Lu Guiyan to find out the truth of the year. Because he——"

Guan Chen clenched his palms, "He said that in the past years, he really regarded Lu Guiyan as his own brother, so he didn't have the courage to face Lu Guiyan and tell him those things in person, so he could only use others to tell him."

"There was also the time when Lu Guichi was about to return to his country and was surrounded by Lu Guiyan's men. In fact, he could have escaped at that time. But he knew that they were sent by Lu Guiyan, and he felt guilty for a moment and thought about just surrendering and being taken away. But I arrived and took him away."

For a moment, Lin Wu’s chaotic thoughts were indescribable, but he felt a little uncomfortable.

Previously, she and Bo Yuting had many doubts and speculations about this, and even thought that Lu Guichi deliberately let Lu Guiyan find out so that he could take the opportunity to return home smoothly.

But if you think about it carefully, they seem to have forgotten one thing. If she asked Guan Chen to go, Lu Guichi would not have guessed it in advance. So how could Lu Guichi be caught on purpose? He clearly didn't know that there was a good opportunity to escape after being caught.

Therefore, even though there were many loopholes and it didn't make sense no matter how you thought about it, the fact that Lu Guiyan found the caregiver and almost arrested Lu Guichi was actually due to a very simple reason -

He really treated Lu Guiyan as his brother.

At that moment, his brother Lu Guiyan was more important than anything he had to do.
