Reincarnated as a Round-Headed Old-Timer, I Grow Stronger Just by Hissing

College student Pei Yu was listening to the “Hajimi Song” while crossing the road when a Dayun truck forced him to reincarnate in another world as an orange cat abandoned in the forest. He unexpectedly awakened the Hissing System: hiss, eat, kill enemies, and grow stronger.

If he can beat them, hiss!

If he can’t, hiss… then run.

Human powerhouses? He’ll hiss at them all the same.

His dream is to grow strong enough to hiss at anyone.
