What an incredible anti-climax. And good for MC to make sure they won't interfere with his agenda.
Now, what's the catch-

Putting them in the same bath was probably the reason. Though their heterochromia could also be to blame.
Good-byes are inevitable~ No clue if MC ever has a chance to return to these worlds.

Pills are literally essential when it comes to the arts of this world. I'm afraid even if MC were to learn the 3, combining them would be fucking useless without the specific pill of the art. Maybe he'll conveniently come upon the extinct ingredients in the main world
I was riiiight. Aside from the last guess.
SEGS

MC was completely lying over being able to control the evil power. Even he can't fucking do it without spending a million Origin points. Those evil seeds are a plague on this mid-level martial world.

Mc is such an evil-looking manipulator.
Can't fucking tell, is the Joyous art of Celestial Demons the forced suicide bombing art?
Such a horrible martial arts world this is. You get strong physically and mentally, at the cost of life span, and the fact that it's impossible to learn any of them without a fucking pill with the possibility of the ingredients getting extinct.

Did that dude's art only give him longevity? He only used ancient lost arts in the whole fight.

Is his internal energy enough to spam the rainbow escape move now? Otherwise I think using the fingering technique would've counted as cheating

Yoooo, 150+ chapters and we finally got introduced to the Evil God concept

I dunno, these 3 losers might be the least suspectable to the evil seed

Kek, shouldn't have been so cocky~ Anyway, why is mans searching for them again?

Obstruction? He gonna ruin their plans or sumn'?

MAKE HUMANITY GREAT AGAIN
Would using that defense/rebound art be considered cheating?

That back be looking weird as fuck
How did MC's predecessor handle this exploding problem?
Damn, another life span lowering art- how the fuck does one fix that?

Fr?

Yaaaaay~ MC's sincerity barely got through this old geezer!~

Segs?

At least that asshole took care of those people so MC wouldn't have to do so himself.

Nux Scans of days past did much worse

MC's casual outfit goes hard. Probably because everything looks good on him.
Oho, double swords.

Interesting choice of rope tying-
Let's see if mans is gonna get this cultivation method of some fekin whales or something more interesting looking, but less suitable.
