The so-called preparation plan, naturally, is to deal with them.
Jiang Xiaobai's main purpose for entering the Mad Demon Secret Land this time is to rob all of these guys, not leaving a single one behind!
Otherwise, considering the way he's been going about things, when would he be able to help his two fathers break through their current levels?
Hmm, it's just a robbery, nothing more.
Murder, of course, is out of the question. Though he knows that failing to remove the roots may lead to big trouble, he simply can't do it.
These top-class forces and the sons and daughters they have in the central region of the Eastern Domain, if he were to kill them all, boy that would cause a ruckus.
As for Jiang Xiaobai, he wouldn't be able to stay in the central region of the Eastern Domain any longer.
At that point, every force of the Eastern Domain would join together to hunt him down. Unless he straight up becomes a Transcendence, it will only lead to a dead-end.
"Alright then."
