After Signing in for a Hundred Thousand Years, I Actually Became the Little Girl's Guardian Spirit

Su Ye traveled through another world and signed in the darkness for a hundred thousand years. Once the seal was released, he became the guardian spirit of the useless girl Gu Xian'er. Gu Xian'er was bullied by her family because she could not awaken her guardian spirit. The appearance of Su Ye completely changed her fate. Armed with the skills, artifacts and elixirs accumulated over a hundred thousand years, he crushed powerful enemies along the way and helped Gu Xian'er grow rapidly. From the Gu family's martial arts arena to Tianyang Academy, from trials in secret realms to the road to the afterlife, this unique pair has constantly encountered covetousness and challenges from all forces. With the emergence of mysterious beings such as Ping Xin and Tai Yi, Su Ye found that he seemed to have been involved in a chess game that spanned eternity.
