Quick Family Recap if anyone cares:
First Brother, Sunyoo is part of demonic cult
Second Brother, Seomoon is part of the government (Lee Kangjin the administrator at this time now)
Third brother, died from protecting family from the merchant bastard
First Sister, Eun Jeong the blue hair girl is with some organization not sure what tho but is learning martial arts I think while being a courtesan
Foruth Brother, the slit eyes is part of the Unorthodox Association and is the leader disciple
Fifth Brother, the one with the head bun is part of an assassin clan ( The Fourth and Fifth met like 2-3 chapters ago)
The Pink/Magenta Haired Twins:
The Sixth Brother, Socheon is with the Wudang Sect and learning from the Grand Elder
The Second sister, Soyul is with Eun Jeong

Sunyoo has met with Eun Jeong, Soyul, and Seomoon. I think those are all the kids

From the translation site and what I remember. Three of the author’s work is connected in the same time line. It would be like this, Fist Demon of Manhua then Lee Gwak then Reaper. Seems like years between the series. There was that time in Lee Gwak when he found that painting of Damho while training and repairing traps, and they talked bout the strongest warrior of mount hua of that era, I don’t know how long Lee Gwak was set after Fist Demon. The Celestial Demon Troupe is most likely the same one in Lee Gwak, maybe the name changed after Fist Demon, since the demonic cult was know as the Divine Cult or something . It looks like Pyo Wol martial art is similar to Gwak art cause of the snakes, unless I’m wrong, hopefully they could meet if Gwak is alive. Really wished author kept working on Lee Gwak so we could see how Celetsial Demon Troupe war or Great Demonic War went. Any novel readers have any info about this? (Sorry for the long comment)
