Chapitre 414: Rematch

Fein glanced at the cover of the book. And when he saw the title... His pupils shrank in an instant. Now, he understood why the Ceterus and the four S ranks valued the book so much!

He held the book tightly in his hand, as this book would be the key to covering one of his major remaining weaknesses. He didn't know how complicated or how hard to learn the book was.

Fein even doubts why the five S ranks, who were clearly a peerless genius, were unable to comprehend the book. But does it matter to him who can upgrade his talent? With the combination of his S rank, reasoning, analysis, memory, and comprehension. He knew that he had a high probability of succeeding! Confidence? That's what he was best at! If S rank talent wasn't enough to understand the thick orange book. Then upgrade to SS rank! If that wasn't still enough... Then SSS rank!! 

"Don't worry, I won't let this book go to waste. You can rest assured." Fein looked at Zaro with a grateful expression.
