Returning from Tribulation, I Open the Cultivation System to the Whole World

The main character is already at the highest level, but he can still be stunned by others, and even become serious when encountering trivial things. Then don't set such a high level at the beginning. He is obviously invincible, and it's boring to write it as a rookie.

The whole world is a place for physical training and Qi training. As the protagonist, you have already passed through the tribulation state. Is it interesting to play with children and practice physical training? Why is Invincible still hiding? He ignored the nuclear bomb.

This protagonist has lost his Mahayana cultivation in vain. How does this mind have such a high cultivation level?

I feel like any orthodox Jindan monk who comes here can slap the tribulation-transcending monk here to death.
