I Sacrificed My Lifespan to Become a God. If I’m Not Invincible, Who Is?

[Invincible power fantasy + game merges with reality + ruthless and decisive + a rich cast of female leads, none of them window dressing (dddd)] A game descends upon the world, and everyone awakens a talent. Su Yuan transmigrates to this world and gains the ability to enhance things by sacrificing his remaining lifespan. As long as he spends his own years of life, he can enhance anything. [Steel Pipe (Shabby)] → [Steel Pipe of Judgment (Rare)]: 100% critical hit rate; a headshot is always fatal, and a hit to a limb always leaves it crippled! [Fruit Knife (Common)] → [Demon Blade: Fruit Cutter (Epic)]: The defense of every target attacked is reduced to that of an ordinary apple. Time to cut some fruit! [Black Cat (Excellent)] → [Secret Lord of the Gods (Mythic)]: A remnant of an ancient evil god, impossible to look at directly, impossible to describe, beyond words, a great being who transcends time and space! Su Yuan stares at the catgirl beside him, his face full of uncertainty. After a moment’s hesitation, he says: “System, help me spend another Jurassic period’s worth of lifespan. Thanks.”
