The male protagonist accidentally swaps souls with a pig and discovers the secret of pigs: every pig is a human reincarnated, and some can even swap souls just like he did. Legend has it that if a pig keeps staring into your eyes, you have to kill it. This pig is intelligent, and it will do everything it can to swap souls with you and take your place, leaving you to face its punishment. If you can’t swap back with it before your limited time runs out, it will replace you forever, and for all eternity, you’ll be nothing but a pig…
In the beginning, he turned into a pig𓃟 and gradually upgraded, then upgraded again, and turned into Iron Man 😂
