Randolph realized the mistake he made when facing the homunculus while in the Shadow realm. Originally, it had also happened when Randolph fought the dire wolf as well as the two remaining homunculi. However, two people from his party immediately asked to fight the homunculus.
"I will fight one of the homunculi," said Bazeki looking excited. He also looked at Randolph as if sarcastically.
Sin immediately grabbed the remaining homunculus, "Leave the others for me. I'll tell Randolph how to easily kill a homunculus."
Randolph did feel annoyed with the two grown men. However, he gained a piece of valuable knowledge from both of them. Even though both of them used their full skills against the homunculus, neither of them gave off an aura and used skills that required mana.
"Homunculus won't change their form if the opponent in their closest vantage point doesn't use their mana and aura in battle"
Bastian seemed to explain it to Randolph.
