From player to legendary npc

From the strongest player in Infinite Realm , to the strongest npc, Will he be able to beat the bosses and advance the phases or will he die again?

After a while, I was confused on how I wanted to continue this, so I took a break from writing anymore chapters, I now know exactly what the story will be, and how it will progress in the future, starting tomorrow I will officially start this book and try to write one chapter per week
