Goo Hwi, the Heaven Ravager King (천잔왕天殘王 구휘, Cheonjan-wang Guhwi; "Heaven Ravager King, Goo Hwi") is a senior member of the old murim, being a part of the Sage Forest, and the leader of the legendary band of assassins the Black Snake. In the past he was feared as one of the Twelve Supreme Masters, being one of the Four Heavenly Kings of the chaotic murim.[1]


Goo Hwi is a giant of a man with a dense bulky musculature from years of intensive training, black hair tied back into a short spiky ponytail, his thick black trademark moustache over his lip and a distinguishing scar running down over his left eye. He has a tattoo of a black snake on his left shoulder, signifying his association with the Black Snake assassins.
Several decades after the war against the Asura Blood Sect, Goo Hwi has aged noticeably with his once black hair and moustache having now gone completely grey. He also gained a second distinguishing scar on the left side of his chin.

Goo Hwi is generally quite a cheerful entity and quite level-headed. He has a protective nature and will help those aligned with his family's organisation. While Goo Hwi will happily avoid conflict when possible, if the situation calls for it, he is more than happy to show serious force.

While he has mellowed out in his old age, Goo Hwi loved to fight in his younger days, showing no hesitation to challenge others in any situation.[2][3] Even when facing powerful opponents, he is absolutely fearless and confident in his victory. He is also a very prideful man, often boasting about his fame and calling his martial arts the most powerful in the Middle Kingdom.[4] Although he is a murderer, Goo Hwi has some sense of honor. He does not lay his hand on weak and innocent people or attack merchants and common folk for private gain.[5][6] Goo Hwi also spares opponents that are not worth killing or people who turns their back on him and walk away but he has no exception for those that harbors hostility towards him.[7] Furthermore, Goo Hwi holds a grudge against those who had wronged him as he was willing to track down Yongbi and Cruel Moon Archdemon to exact his revenge on them.


Goo Hwi once led the Black Snake in a conflict against the Cheonwoong Faction where he slaughtered forty of their elite warriors and faced the Divine Lord of Destruction himself.[3] According to Goo Hwi, the war first started because the members of the faction killed some of his men.[8] At some point before being captured by Yongbi, Goo Hwi gained infamy for terrorising the entire Northern Murim.[9]


Yongbi the InvincibleEdit

Volume 1Edit

Goo Hwi humiliatingly traveled through the murim bounded in chains, having been captured by Yongbi. On the way, all attempts to escape and rescue him were thwarted. While setting up for the night, Biryong fished a young boy out of the river and when Yongbi dried him off on a spit, Goo Hwi worried he might be a cannibal. In the morning, Goo Hwi wondered who the people hiding nearby was, knowing that his men would not leak such obvious murderous intent. After he watched Yongbi effortlessly deal with the two men, he attempted to warn the boy about Yongbi's deception but was punished for it. Later, they arrived at Hobuk Province and Goo Hwi was thrown in prison where he was accosted by other prisoners much to his chagrin.

Later that day, it was revealed that Goo Hwi managed to subdue the other prisoners. When his pressure points finally released, Goo Hwi freed himself from his shackles. On the way out of the castle, he encountered the boy from before. Goo Hwi grabbed the boy and questioned him on the whereabouts of Yongbi and Biryong. Threatened, the boy lied about their location and attempted to enlist his help to escape. At the gates, Goo Hwi hilariously attempted to leave by posing as a mother with a sick child but the guards easily saw through the disguise because of his bulky size. The guards then attacked him but Goo Hwi released his ki which smashed the gate and created a massive explosion that engulfed his attackers.

Soon after, Goo Hwi and the boy, Yul Mugi were found lying on the ground unconscious with two spears impaled in Goo Hwi's buttocks. Yul Mugi woke up and grabbed onto a spear for stability, unwittingly impaling Goo Hwi further. He was woken up by the pain and Yul Mugi pretended to be asleep to escape his wrath. After tending his wounds, Goo Hwi promised revenge on Yongbi and resumed his travels, mentioning that he would drop Yul Mugi off in the first village he comes across. As Goo Hwi left, two mysterious men secretly observed him, noting that they cannot retrieve Yul Mugi in his presence. Unable to face off against Goo Hwi with just the both of them, they sent a message to their prelate for assistance. As the messenger hawk took flight, a spear flew rapidly from below and impaled the hawk, killing it. Goo Hwi then appeared above the two men and inquired who they were.

Between the events of Yongbi the Invincible and Gosu (The Master)...

Goo Hwi was involved in the Old Murim Alliance's war against the Asura Blood Sect. Shortly after this war, he, Yongbi and Hong Ye-Mong fought against and permanently injured Sa Paecheon,[10] which eventually lead to Sa Paecheon's consecutive defeats against those affiliated with the Heavenly Destruction Sect.

Gosu (The Master)Edit


Finding Gha Woobok severely injured on the side of the road, he found shelter from the rain inside a cave, where he helped Woobok recover. A short while later, a patrol from the Naeseonhyang came by, intending to capture Gha Woobok, and were instantly laid to waste. 

Several days later, he was shown observing Gang Ryong from a distant mountain. He was impressed when Gang Ryong noticed his presence, and told a penitent Dang Gan, who is visibly terrified, that he could understand why he was beaten. After picking up the medicinal herbs he needed to treat his sick friend, Goo Hwi then left on his journey back, much to his granddaughter's sadness.

Season 2 IntroductionEdit

Having housed him briefly, Goo Hwi and the other senior members see Gang Ryong off as the young gosu left to head back to Yellow Dragon Mountain.

Revived Heavenly Destruction SectEdit

At their compound, Goo Hwi tended to his daughter before seeing Garyeong off. On his way back up, he discussed with Yongbi about his annoyance that people in the murim had poisoned his daughter, adding that he wouldn't get involved in the current murim's business unless it involved his granddaughter or the Baekma Valley.

Powers & AbilitiesEdit

Despite being advanced in age, Goo Hwi appears to have retained at least some of the immense power of his prime, being able to effortlessly take down a patrol of men that challenged him.[11] In the past he was feared as one of the Twelve Supreme Masters, being one of the Four Heavenly Kings of the chaotic murim, which speaks volumes about his strength.[1]

During the days of the old murim, Goo Hwi was an extremely powerful combatant, being blessed with the perfect body for martial arts,[12] and having mastered the legendary Seven Step Black Wind Fist. Goo Hwi was also considered one of the top ten strongest men in the Middle Kingdom (he personally considers top three).[4] Even Hyeon Jae-Yang, the Divine Lord of Destruction, mentioned Goo Hwi as the strongest person he had ever faced.[13] At a young age, he was already revered as the strongest warrior of the chaotic factions not because of his martial arts at the time but because of his enormous potential.[14] Due to his fearsome strength, he was able to retain this title.[15]

Immense Inner Ki: Goo Hwi has obtained an incredible amount of inner ki since his younger days, greatly boosting his power.[3] He is also capable of putting up reflective ki barriers to block and disperse the damage he would incur from powerful attacks.[16][17]

Immense Durability & Endurance: He has an extraordinary constitution,[18] showing numerous feats of durability and endurance. Goo Hwi's muscles are described to be like steel, unlikely to break no matter how his opponents strike them.[16] He is also able to take powerful blows and keep on fighting as seen in his duel against Yongbi.[17] His durability is further proven when Goo Hwi manages to walk off after receiving grievous wounds from the High Elder of the Cheonwoong Faction and Cruel Moon Archdemon.[2][18]

Immense Physical Strength: Goo Hwi boasts incredible physical strength, being able to easily level enormous objects and heavily scar the earth with his strikes.[16][17] Goo Hwi is also able to crush a person's head with his bare hands.[19] Another testament to his strength is that he was able to effortlessly shake off Chomu's grip, which can crush rocks with ease.[20] Even if an opponent deflects his attacks, they are still powerful enough to rattle their bones.[16]

Immense Physical Speed: Despite his bulky frame, Goo Hwi has surprisingly impressive agility.[16] He is extremely quick when attacking, being able to close small distances instantly and tear his opponents apart in a split second.[21]

Internal Resistance: After receiving medical aid from Gongson Seung, Goo Hwi developed internal resistance that allowed him to resist the effects of the Demonic Technique's poison.[18]

Seven Step Black Wind Fist: Goo Hwi's attack moves are so varied that it is impossible for the opponent to guess their range.[16]


  • (To the Naeseonhyang patrol) "It'd have been better if there was an option to 'pretend we never saw each other and went our separate ways'... but if I have to choose between the two you offered, I'd have to go with being dragged away by force."[11]
  • (To Biryong) "How could I forget that? How scatter-brained I am.. that the horse and his master are both bastards...!"[22]
