What is the ending of the book The Underworld Student?

The first part is about Xia Yu creating a brand new Tianmen

The second part is about Xia Yu’s son Xia Tianmen taking over Tianmen

The third part is about losing Qiang and Dandaofeng. Together we were elected as the top 13 brothers of Tianmen

The fourth part is about Shen Can but it is not finished yet

The fifth part is newly written and has almost nothing to do with the previous ones

Hope you are satisfied
