After Three Generations of the System, It's He's Turn.

[Contract Rebirth × Soul Transformation × Two-way Redemption × Chinese Reincarnation] At first, Lin Wan thought he was reborn. Later, Lin Wan thought that rebirth was the contract between Shen Zhi and the system. Then she can do it. This time, she returned to the beginning of the story: When Lin Wan and Shen Zhi were seven years old, everything started again. But—— There has never been any rebirth in this world, it is just your dead soul's efforts to purify it again and again. It's like an unfinished question will come up again and again until you come up with a new answer. Just like AI, it can never replace the human brain. It's neither fast-paced nor refreshing, but rather old-style writing, which will most likely not please readers. It's purely for the author's own entertainment. The author is not a eunuch and will work hard to code until the end. It's up to you whether there are readers and whether you can read it to the end.
