"We thought you'd stay in the 'Fortress' until the day you left..."
As Big Cat's stronghold and R&D base, the research institute was brimming with defense systems – heaven knows how many traps a Quasi-God Big Shot had hidden in there, and the kind of boosts her inheritor might receive within its walls.
Probably, as long as Lu didn't come out, his safety could be assured – at least until the clueless losers foolishly knocked on the door and became cannon fodder.
"Ha, if I really did that, I'm afraid I'd never see the day of departure."
Theory is theory, reality is reality. Amidst a pack of wolves, a strong presence is far more effective than a secure fortress... really waiting in the 'Safe Zone' for the Storm to pass, they have ten thousand ways to drag you out/ deceive you/ force you out.
Although Lu wanted to slack off a little longer... to accumulate some strength, the feedback from Lulu suggested that he could not wait any longer.
