Hyeol Un Ma Je 혈운마제(血雲魔帝)
is a title again = which was translated to 'Bloody Devil', the hanja was not provided in the raw, above characters say 'Blood Cloud Demon(ic) Ruler/Emperor' - implies blood mists/clouds as a weapon
I like the ring of Blood Cloud Demonic Ruler as it distinguishes 帝 Je from 皇 Hwang which we've already established as an existing term/group, the Cheon Mu Pal Hwang 천무팔황 (天武八皇) Eight Heavenly Martial Emperors (see below for further explanation; also in Chinese 皇帝 is used together for Emperor, but it gets more complex than that)
Bun Un Nyo Je 분운뇨제(糞雲尿除)
which was translated as 'Feces Urine' has an expanded meaning 'Feces Cloud Urine Release', is a play on the above title.
I had a little more time to do some comparisons of the chapter terms/glossary against the raw & novel, these hanja come from an older chapter of the light novel - these 2 groups appeared in the Manhwa Chapter 3:
S(h)in Jin Yug Dae Cho In 신진육대초인 (新進六大超人)
is a title for a group = was translated as "The New Six Great Super Warriors" of which the 'Dark Spear Demon' and the 'Blood Cloud Demonic Ruler' is part of; an alternate reading per the Hanja would be the "Newly-Advanced Six Great Super-humans" or some other variation.
This was previously translated in the Manhwa Ch 3 as the Rising Six Great Heroes (not so heroic heh)
I like the ring of : The "Six Contemporary/(Rising is good too) Transcendents"
this group was compared to the:
Cheon Mu Pal Hwang 천무팔황(天武八皇)
is a title for a group = was translated as "The Greatest Warriors in the World" (which is off the mark) of which Palm Emperor is part of; the character readings can be translated as the "Heavenly Martial Eight Emperors' or some other variation.
This was previously translated the same as here (Greatest Warriors in the World), in the Manhwa Ch 3 too
I like the ring of : The "Eight Heavenly Martial Emperors"
