Just a few days ago, when Rivers approached the "Pure Blood Will", he was interrogated about Link Grande by a girl named Sophie Lucia.
At that time, he was puzzled.
Why would a local apprentice from Lucia Family in Mitchell District, which was considered a big family, be so concerned about a rustic "New Blood" from Stormy Sea?
Out of curiosity, Rivers spent some time and magical stones buying related intelligence.
After reading the intelligence, Rivers understood the two academic disputes between Sophie Lucia and Link Grande, as well as Link Grande's recent research achievements.
In the battle with Antoine Hilton, Rivers managed to kill Antoine, but he himself was seriously injured.
