Guan Chen hesitated for a moment.
Then he thought, since he had already told Lin Wu so much, letting her know to that extent, admitting or denying the rest made no difference.
With this in mind, Guan Chen felt slightly calmer, yet when he spoke, his mood was still grave. He said, "Lu Guichi, he is indeed from the Underground City. That's why he's different from us ordinary people, possessing extremely special abilities."
"And his cooperation with the Huo Family is indeed because he wants to open the entrance to the Underground City and go in."
"About this, I asked him, and he said that the entrance to the Underground City has always been tightly sealed. People outside cannot enter, and those inside cannot leave. It's only a person with a tattoo like the one on your body who can move freely in and out. That's why he couldn't open the entrance to the Underground City by himself, which is why he cooperated with the Huo Family."
