It was a little trouble to clean up the Goblin village, but what was coming after this was a major problem.
The reason, Kenta gathered all of those adventurers and pay them out was for the coming event. It was Goblin Raid, and most of them are usually set at night period.
Which was the second reason, why Kenta burnt the whole forest down. With that, they will have a clear view of the battlefield even at night period, even though for him having a forest or not doesn't matter at all.
If I can get a light magician along with me, after all, it was the fastest element out there along with the Time attribute.
It is said that time is slower than light, that is why in previous worlds time was always calculated with the speed of light or we can say a light year.
But in true meaning, time is something we can measure within our senses cannot capture. While light has been the definition of something humans can never grasp, calling it the fastest was not wrong.
