There's a saying that's quite accurate—the one who understands you best is always your opponent.
Therefore, Urias actually knew Bluru quite well, though the latter was slippery and sly, he did actually have a bottom line.
This bottom line wasn't because Bluru had much of a conscience, but rather that he would never become a servant just to stay alive.
Moreover, Urias could also sense that Bluru's attitude toward Ye Feng was not just one of fear but also carried a deep-seated respect.
This meant that currently, he had willingly become Ye Feng's subordinate.
And when Bluru arrived, his first statement was earth-shattering, "Following Lord Ye Feng, you have at least a ninety percent chance of safely surviving the cosmic calamity."
"How is that possible!!!" Urias said, his face filled with shock.
Seeing the reaction from Urias, Bluru was quite pleased. The rest was easy, introducing Ye Feng and the World Tree, especially the ability of the Inner World.
