With godlike talent from the start, how did he become invincible?

[All-out Transmigration × Multiverse Domination | Decisive Killing! God-like Talent from the Start!]
Earth has been chosen by a mysterious force, and all its inhabitants are forcibly drawn into a multiverse conquest game. Each person is randomly assigned a talent and transported to a beginner's continent—where the weak are eliminated and the strong are respected.
Lin Tian awakens his SSS-level talent [Enhancement]: Gain enhancement points by killing enemies, which can be used to infinitely upgrade the rank of all items!
He decisively used two costless opportunities to activate [Enhancement] on his talent.
[Talent: Enhancement (Unique)]
[Rank: ∞ (Beyond God-level)]
[Effect: Guaranteed "Upgrade Points" upon kill, which can be used to upgrade any item, skill, or talent without cost, with no upper limit!]
From that moment on, an existence that transcended the rules was born.
Slaughter is his path to advancement!
