[Traveling through another world + System training + Counterattack invincibility]
I accidentally got lucky because I was helping an old lady cross the street, and I ended up in this fantasy world where I only trained my physical body, and became the most humble slave of the landlord's family! The beginning is hell mode, with whipping, humiliation, and being inferior to pigs and dogs.
It wasn't until the [Infinite Bodybuilding System] was activated that I realized that the world's bodybuilding techniques were full of loopholes!
It is better for others to practice hard for ten years than for me to hang up for one day. If you practice the black iron body, I will become an immortal golden body; if you reach the vajra state, I will have already forged the eternal holy body!
Fight out from the slave camp and rise from the mountains of corpses and sea of blood. I once defeated the genius of a family with one punch, and also defeated the ancient sect with one kick. All the gods and demons in the sky are just slightly larger sandbags in front of me.
In this life, I will not cultivate spiritual power, nor borrow any external objects. I will use only a pair of fists to reach the ninth heaven, and become immortal with my physical body!
