"No need to be embarrassed; an addition of one person isn't a big deal, right?" Luciel said to Richard and then turned to Treyton.

"I—I don't have any superpowers, but I can still kill a few zombies if needed."
"Oh, you've killed some?" Luciel asked, interrupting Richard.
"Yes, I needed to kill some zombies to survive while following others to come here.
But I'm not that skilled in doing it, unlike other people who had some skills in dealing with zombies efficiently. I can only deal with the weakest zombies."
