Protagonist (book wearer) Jiang Yu, a professional book wearer, takes on missions to make money, does not save anyone, just "completes plot corrections"
Villain (Fragment of the Main God) Shen Yan, in every world is a sick, paranoid character who will not end well. He is actually the main god, split and sealed by some kind of power in one hundred thousand book worlds.
Reason for crossing the book: Jiang Yu accepted a high-stakes bounty mission: enter 10 designated worlds, "contact" the villain and record his behavior patterns. The mission reward is enough for him to retire
The truth: Shen Yan is not from the book. He is the Lord God who created all the worlds. After being betrayed, he split into a hundred thousand pieces, trapped in a sick story of his own creation, always playing the villain, and never being loved. The person who issued the mission to Jiang Yu might be someone who betrayed the Lord God and wanted to use Jiang Yu to completely obliterate Shen Yan.
The ending: Jiang Yu discovers the truth in the tenth world, changes from "for money" to "for him", confronts the Lord God, and finally chooses to awaken Shen Yan
