the gamer is a personal specific ability unique to him alone. so on that note, enough with all the rubbish that is 'mom is an npc' or 'mom is final boss'
give the author enough time to build the story properly and flesh things out. while his mother may have known he has an ability she likely didnt know what it was any sooner than he did, or to be frank any sooner than the old guy from chunbomoon did as i assume he has talked with her about it.
the abyss guy met him because of some one he knows, i assume that was his mother and/or possibly the old man though more likely his mother/father (who we have yet to know ANYTHING about)
it just seems to me the family has natural ability users run in the bloodline.
unless of course the story goes on to say that his mother didnt give birth to him and that gaia itself just created him from nothing then granted him a near godlike ability, which would simply be terrible story writing and should shame the author forever if used.
going on normal simple logic, the ??? applies to either those whose power is faaar too high for jee han to allowed knowledge of, or it is applied to those who have a kind of power that even gaia itself cannot quantify to a specific measurement, for example immortals, dieties etc tend to fall outside the realms of natural limitation (2 of the same being can be nearly identical and yet worlds apart from each other)
i dont post comments to criticize or insult anyone. but there is a certain level or common sense, experience and intelligence that needs to be used when 'analyzing' something especially when your trying to make a judgement about an MC's family or closest relatives before being given ANY information at all. common sense varies per situation so cannot be applied here, experience is thus applied on the basis of similar themed stories and similar plots with their individual twists as chosen by their respective authors, this takes a lot of reading in various genre's and fields and can only give rough estimates of possibilities. as for intelligence, the individual making the comment needs to have enough brains to first judge whether what they post is a possibility or probability as compared to the craziest outfield idea they can come up with for a response. if you feel like it could happen follow it up with why you feel that way and what 1 thing provided (even if its a silly tiny little detail like a persons level and title not being displayed, or something minor chances that always was the same) supports it, otherwise you say something that is just plain ridiculous that will only get the return response of 'do you use your head at all?' popping up in the heads of each person who reads your post.
just for sake of saying it again, jee han is the only one to whom the gamer ability specifically affects, although through the party feature and possibly future new features he can involve others to a certain degree. to even consider his mother of being an npc is to suddenly assume that the entire world and gaia revolves around jee han alone and runs for his sake, it also begs to differ whether you even consider jee han himself (the 'npcs' son!) to be human or just another slave to his ability, in which case might as well not read it anymore as it's likely not going to get all that more enjoyable to read. yes i understand the way i phrase this post makes me sound like an ass, but i only tolerate the average level of idiocy/randomness and not much more. people are born with brains able to reason, and to see them not even attempt it is something i have been raised to consider offensive. sorry
