Start with a Wooden Stake and Keep Getting Beaten to Become Invincible

Dou Ai's mother's soul traveled through the world of immortality and became a wooden stake for disciples of the sect to practice. I was bombarded with various spells and flying swords every day. He actually gradually became resistant to these attacks. Little did they know that this was the beginning of invincibility. Because he was too bored, he decided to escape from the sect on a dark and windy night. "I quit! I want to live a rose-colored life of cultivating immortals!"
