The Black Heaven & Earth Technique (Hyun Chun Ji Gong), is taught by the Black Heaven & Earth School. It is the ultimate power distribution technique, coveted by all the Murim. It is the only technique strong enough to deal with the amount of Ki let off by the One Moon Divine Dan.
This greatest of the Ki Circulation techniques was taught by Un-Wol to Chun-Woo Han who then passed it on to Shi-Woon Yi. It is envied and coveted by many masters and elites, most notably the Former Alliance Chief.
This technique is the reason for Un-Wol's exile. After mastering the technique, he was brought before the Martial arts alliance chiefs to demonstrate its final stage. After starting the demonstration Un-Wol unintentionally entered the Black Origin Threshold and blacked out. Upon waking up, Un-Wol discovered that he had slaughtered all the Munju in the room with no visible damage to himself.
The specifics of the technique have yet to be explained in detail, but it is implied that the technique allows the user to become far stronger than they would be without it.
Some possible explanations of its use may be seen when Shi-Woon is training under Chun-Woo when the latter explains that Ki exercises will bring your basic skills such as speed and strength up to a new standard. It can be hypothesized that while any Ki circulation technique accomplishes this strengthening the Black Heaven and Earth Technique does so to a greater and perhaps even faster degree. It may also be the source of Chun-Woo's massive Ki supply and superhuman healing abilities.
Despite its advantages, it is extremely difficult to use, shown when even Goomoonryong fell into a blind rage upon using its purest form, the Black Origin Threshold.
Black Origin Threshold (Hyun Wonji Gyung): The purest form of the Black Heaven & Earth technique. The Black Origin Threshold causes the natural flow of the Ki to flow in reverse and signifies the moment when one surpasses the limits of the consciousness and the subconsciousness, the enemy & the self, and becomes the purest "Mu" (Fighting Spirit). Black Origin Threshold is the essence of the Black Heaven & Earth technique, but at the same time, it is the greatest fault. Those who have attained the threshold in the past were all swallowed up by animal-like emotions, and lost their sense of the self.
Chaotic Heavens Destruction StrikeEdit
Chaotic Heavens Destruction Strike (Hon Cheon Meol Gyuk): It is the most powerful technique of the Black Heaven and Earth Technique yet belongs to the Rising Fist Arts. Due to knowledge not yet explained a user must take three steps back to execute the technique. It seems to be an external Ki strike of great force. When used against Shi-Woon in the Black Origin Threshold State it managed to mangle the left side of his torso seemingly ripping a hole in his side, with his bones apparent from outside. His arm also hung limp after the attack.
