Invincible + golden finger + no heroine + brainless power fantasy
Lin Yi transmigrates to a parallel world and becomes a young man left behind in a run-down Taoist temple.
The old Taoist has already passed away.
The good news: His golden finger lets his words become law. Whatever he says comes true.
The bad news: It's a dilapidated temple, and he can't even order takeout.
No matter. First, let's try out this golden finger.
So he says, “My physique is as strong as the mightiest primordial race!” Instantly, thunder rumbles, as if warning him of something!
Oh no, I think I've made the cheat way too powerful!!
For the sake of his own happy life, and so humanity doesn't get itself killed by making him overdo it,
Lin Yi has no choice but to set out on the path of ensuring humanity's survival.
The cheat code is sometimes there, sometimes not; it's absent at crucial moments.
Sure, actually it's not bad. The way it's written at the beginning might suggest something that needs to be hinted at later... To be honest, you don't have to kill the Heavenly Dao; you could just take it as a dog. Wouldn't that be much simpler? You could play it however you want.
