"Evan, when are you going to join the Demonic Tree?" Rave said calmly.

"As I said before, I want to do one experiment first. After that, I will go straight to where I was told. As I understand it, there will be a formal joining ceremony." Evan quickly replied.

"I see. Then I must make one more condition for you, don't get me wrong, I'm doing this for security purposes. You may be a valuable ally, but you may also be a dangerous enemy, so if you don't join us in a year, I will personally kill you." Rave said coldly.

He wasn't going to force Evan to join their organization right now, but he couldn't let Evan procrastinate on this event.

"Okay, I agree," Evan replied.
