Martial arts dominates the Gosu (The Master) world with many gosu (고수, gosu), of all levels of power, using different styles. While outer ki and inner ki both exist, inner ki is a major part of a martial artist's strength. It has been noted that in the hands of a gosu with great inner ki, even a dead leaf can become a weapon that can pierce iron plates.[1] Despite this, outer ki fist arts can also be quite formidable.

The bodies of martial artists (and regular humans) have various important points on the body that determine ki output as well as one's mortality. There are twelve ki veins and eight erratic ki passages which are joined by the regular flow of one's ki.[2] As well as that, a person has nine fatal points.[2] If these fatal points are disrupted and a person continues using their martial arts, these fatal points will burst causing a ki overload and ultimately death.[3] Martial artists also have eight extra meridians on their body that, if opened correctly, boost the gosu's inner ki levels.[4]

Diamond BodyEdit

User(s): Dang Gwe

A martial artist from Hadong claimed he had reached a level of "Diamond Body" (금강불괴金剛不壞, Geumgangbulgoe).[7] Although it ended up turning out that this was a lie, Gang Ryong stated that those of the "Diamond Body" level could pick themselves out of a mountain of rubble after taking the Evil Negating Palmstrike, given a few hours to recover (it is notable that the same man was later shown alive, implying he may have escaped.).

Flying Flash Sword movements

The Soseondang's Flying Flash Sword (소선당의 선광비검蘇仙堂的 眩光秘劍, Soseondang-ui Seongwangbigeom) is a powerful style of swordsmanship that was passed down the Soseondang Clan. The Soseondang Clan existed near the Yunnan Castle and over generations they pursued the "ultimate understanding" of the sword rather than fame or honour.[9] As a result, masters of the style are able to move at nigh untraceable speeds and slice through sturdy walls, boulders and trees as easy as a knife through butter. The swordsmanship of Soh Cheongwon the One Sword, the late 5th Clan Master of the Soseondang, was so swift and sublime that even renowned martial artists could barely follow his movements with their eyes.[9]

The current successor of the Flying Flash Sword style is Soh Jinhong, the Rosy-Cheeked Sword Fiend, a person who does not actually share any blood with the previous successor, Soh Cheongwon.[10]

User(s): Palgongjin Yangso, Gha Woobok

The Life Drain Technique (흡성대법吸星大法, Heubseongdaebeob) is a bizarre and remarkably unique martial arts style that involves the draining and assimilation of ki and life energy from targets. It is a truly enigmatic art that, once mastered, enables its user to harmonise with the ki of natural elements (such as plants and rocks) and utilise their power as one pleases; retracing the martial art's origins, the Life Drain Technique is more like a Sage Art or Taoist Art than a martial art.[11] The art requires a special physical constitution to be able to be learned and, in the days of the old murim, was taught under great secrecy.[12] Apparently, the original purpose of the Life Drain Technique was to absorb the ki of others in order to attain immortality.[13]

Palgongjin Yangso (팔공진인 양소, Palgongjin-in Yangso) was a man who completed the Life Drain Technique. At some point during his life, he passed on the martial art style to Gha Woobok.[13]

Welkin LightningEdit

User(s): Sa Paecheon, Nameless

The Welkin Lightning (천뢰天雷, Cheonloe) techniques are a series of martial arts techniques utilised by Sa Paecheon, the Devil of the Venom Hands. The strength of these techniques is enough that they can clash evenly with the Divine Heavenly Destruction Techniques utilised by both the Heavenly Destroyer and his disciple.

Other AbilitiesEdit

Deadly Barrier: Palace of ConceptionEdit

User(s): Hwan Sa

The Deadly Barrier: Palace of Conception (살진 포태궁殺陳 胞胎宮, Saljin Potaegung; lit. Killing Display/Exhibition Womb Foetus Palace) is a powerful soul summoning technique, similar to the Grand Soul Possession Technique, that creates a powerful illusory space to trap and kill a target. If the target succumbs to the illusions and reacts to them in any way, the illusions then become real to the target. Then, unless they defeat the psychosomatic illusions, they will be killed by them.[14] Despite the technique's fearsome capabilities, it can be broken out of with enough skill.

Grand Soul Possession TechniqueEdit

User(s): Hwan Sa
  • The summoned archfiends possessing a novice...
  • Undergoing Ultimate Metamorphosis...
  • Most people do not survive...
  • The known survivors... the Sky Stars!

The Grand Soul Possession Technique (환혼귀진대법, Hwanhongwijindaebeob) is a forbidden technique that summons the spirits of archfiends who died without finding a successor (to pass their martial art on to), and allows the spirit to possess living novices who will then inherit their martial art.[15] While possessed, the novices must endure body-breaking training that eventually leads to their Ultimate Metamorphosis. Once their training is complete and the possessed novices have fully inherited the possessor's martial art, the spirit departs their body.[15]

However, this forbidden technique comes with extreme drawbacks. For the process to be successful, novices need both a complete understanding of the martial art they are inheriting (as well as being compatible with the martial art itself) and a tremendous amount of ki. In addition, the novices need incredible mental and physical fortitude in order to overcome the extreme pain caused by undergoing Ultimate Metamorphosis during possession. Due to this, despite the strict selection criteria and the many years of training that follow, the number of people that survive this accursed technique are close to zero. However, it is said that those who successfully inherit their possessor's martial art attain a martial arts prowess powerful enough to rule their era.[15]

Survivors of the Grand Soul Possession Technique include the six Sky Stars of the Seven Slayers of the Sky Gorge.[15]

Illusion CastingEdit

User(s): Yang Jeonghak, Song Yerin, Old Man, Hwan Sa

Certain people have the power to cast sensory illusions, ranging from simple ocular illusions (such as changing one's appearance) to overwhelming somatosensory ones (such as making someone believe they have lost a limb). Illusionists try to unsettle their opponents in various ways; the moment their opponent becomes rattled and lets their emotions get the better of them, the illusionist has already won.[16] People who are single-mindedly driven easily succumb to even basic illusion techniques.[17]

According to Yang Jeonghak, the best way to break free from an illusion technique is to not get caught in an illusion technique to begin with by avoiding the gaze of the illusionist and keeping one's composure.[16] However, in the case that a person does succumb to an illusion, the quickest and simplest way to break free is through pain. However, because there is a fine distinction between imaginary pain and real physical pain, seizing the opportunity to break out of the illusion by noticing and using real physical pain comes down to the victim's willpower.[16] Another method of breaking out of an illusion technique is to release a relatively powerful burst of one's inner ki at once, though the person needs to be reasonably more powerful than the illusionist for this to work.[18]

Poison ArtsEdit

There are many deadly toxins that are used in the branch of martial arts known as the Poison Arts:

  • Demonic Blight (마호선麻糊散, Mahoseon): A horrifying poison used by Sa Paecheon. Its effects include the slow degeneration of muscles and tissues.[19]
  • Gu (, Go): A unique class of toxic worms that are implanted into a victim, enabling their user to control the victim's body against their will. Mak Sapyeong was a user.
  • Sage's Demise (신선폐神仙廢, Shinseonpye): A poison that the old man's most recent puppet coated his sword with. While its effects are largely unknown, if one does not begin restoring their ki immediately after being afflicted, their chance of surviving drops drastically; using more ki while afflicted will almost certainly cause death.[16]
