"Master, are you alright…?" Sabian was trembling in fear to see his master vomit a mouthful of blood. His face was extremely pale. He almost looked like he was on the verge of dying, as he was panting so heavily. "Wh- what should I do? Should I call a healer?"
Yet, Lou glared at him, since he knew a healer would be able to tell that he was a sorcerer. That was the identity he didn't want to reveal to anyone else.
Seeing that harsh glare, Sabian immediately clamped his mouth shut. He waited for Lou's order instead of suggesting something that could incur his ire.
The cause of Lou's condition right now was the backlash of his magic. As a matter of fact, the portal that he created to call for the monsters was reopened again, because Sabian couldn't close it properly.
That was the reason for the second monster attack.
