Luca held onto his abdomen that was being regenerated by the blue fire. His white eyes were burning in anger and rage as he received a rather lethal blow from Mephisto. Even when he was with Noah, he had no idea how strong Mephisto was, but he knew that it took a demon prince to badly injure Mephisto. Instead of questioning the negotiator's health, he only had one thought in mind.
If he couldn't kill Mephistopheles, then what were his chances of killing Belphegor?
Mephisto wasn't surprised by this move from Luca. He had been watching demons fight against angels before, and he was well aware of the capabilities of a hellhound or an earl. What's worse was that Luca was not a fighting type of earl based on the power Demence had given him. He might not recover most of his strength yet, but he was not scared of fighting an earl. More likely, if it's someone who had hurt Noah before.
