First of all, i'm wondering how the f*ck MC was able to make taeryong (i think i spelled it right) spit out the poison bug INSIDE HIS HEAD, also how did he not damage his brain?

Shadowless is who killed that demonic leader from that time when he got the shining cube and got teleported 2 the "other dimension" and trained to get the strength he has now, its MC

I thought it was obvious by now. I mean Shadowless is the prime suspect in killing TBP Emperor, who MC killed. Shadowless is suspected to be part of murim alliance's secret force, which MC was part of. Shadowless is known to be almost impossible to catch as if he never had a presence, therefore the name "Shadowless", which obviously "Number 100" or MC was known to be that good in infiltration and presence hiding - the FMC said that and she also mentioned many chapters back that MC learned from the best Tracking Expert in Murim which would help a lot with MC's missions in infiltration and assassination and basically doing the deeds of "Shadowless". And remember, he could literally go through walls which would explain the term "Shadowless". Edit: Right another thing, after getting that power up in the hell looking dimension, For 2 years nobody knew what he did and once again I think somebody mentioned that Shadowless dissapeared after that point........ Or im just stupid and overcomplicated everything

I need season 3 so badly. I'm having sugar withdraws.

Anyway, nice, bro got back
