That was the beginning of all cultivation and the most important stage of laying the foundation. In the later stages, many people actually didn't pay much attention to the polishing of the physical body. This didn't mean that they didn't cultivate, but they would pay more attention to the accumulation of mana, the understanding of the divine arts, and so on.
However, after experiencing all this, he finally understood that the road of cultivation was like a boat going against the current. The body was the boat crossing the sea. If the dharmakaya wanted to cross the other side, the body must be strong enough.
Even if it was just a rotten skin, it was not something that could be thrown away now.
