In the end, Garp and Warring States sent Bai Chen to Impel Down City at a painful cost. But what he didn't expect was that Bai Chen opened a system called sign-in as soon as he entered prison, and the plan to escape from prison was temporarily abandoned. This sign-in lasted five years! Five years later, the sign-in is complete. Bai Chen activated the Susanoo and slashed through the Impel Castle with one strike!
