Have you recommended a novel from another world where the protagonist becomes invincible after experiencing a fortuitous encounter?

If you like novels where the protagonist is invincible after a fortuitous encounter, I can recommend Thunder in the Nine Heavens and The Mysterious Wilderness to you. " Thunder in the Nine Heavens " was a fantasy novel. The main character received the help of a strange book and traveled to another world. He started his own path of being a king and was extremely talented. He attracted the thunder in the nine heavens. On the other hand," The Mysterious Wilderness " told the story of the protagonist, Quan Xing, who obtained the memories of his previous life, as well as his natural spiritual will and the Great Desolate Spell Body, gradually rising to the top of the other world. I hope you like my recommendation.😗
