He knew that he wouldn't be able to last for hours just like what Luciel did.
Treyton knew that Luciel must be very strong and good at combat, but he didn't know he could deal with such a large number of zombies on his own.
And looking at Luciel, who was only covered in the blood of zombies and mutant dogs without shedding a little bit of his own blood, Treyton knew that Luciel could still do more.
Luciel didn't receive any injuries from the zombies or from the mutant dogs, which means that he wasn't struggling in the fight.
It also means that with Luciel's current ability, he could still fight more.
Treyton doesn't know where Luciel got such combat prowess, but it just shows that Luciel was very experienced in fighting.
It was also clear that he was very experienced in dealing with a lot of enemies on his own.
Being good at fighting can be said to be because of talent.
