The Age of Elves: an Inconspicuous Trainer

I just took a nap, and when I opened my eyes, I discovered that there are elves in the world, and these elves are not as weak as in the animation. High-level elves are more intimidating than nuclear bombs. The legendary elves even travel across the world. The protagonist has no system, only a pair of eyes that can read the information of the elves. The protagonist relies on these eyes to walk towards the master step by step. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
