this 1st chapter has a lot of details when describing scenes and items making it a little hard to imagine it, perhaps simplify desriptions a little. I also found the structure of what's happening in the chapter a bit confusing too. As 2 colliding comments an acient village with a boy genius winning an ancient examination and suddenly his younger brother hearing a system voice in his head as his mother faints don't seem related in any way. perhaps you'll clear things up soon and readers will be hooked.
