Can you recommend a novel about the protagonist returning from another world? I can't remember the name of the novel.

The main character cultivated the bone path and returned to Earth from another world. He was originally an Earthling. One's strength could only be unleashed to its greatest extent when there was no physical body and only bones left. What kind of novel was this? Who knew?
The beginning was very interesting. The protagonist died while playing with an inflatable doll, and then he cultivated in another world. After he became invincible there, he thought of a way to return to Earth. Then, it was the content of the novel.
