Different from normal arts, the Nine Dragons Tyrant Body Art didn't cultivate Origin Power. It completely excavated the potential of the human body, increasing the power of blood, flesh, veins, and muscles, and at last, breaking through the limit to become a god in flesh.
To cultivate this art was rather easy. First, eat as much worldly treasures and such tonic things as possible, and second, cultivate for all one was worth, squeezing out one's own physical limits.
This required a strong physique, or else one wouldn't be able maintain such terrifying physical power.
The initial stage of the Nine Dragons Tyrant Body Art had a total of twelve postural styles; the first part of the art, has six styles and apparently the Tyrant Body Art completed had eighteen styles.
The Nine Dragons Tyrant Body Art was to open the nine godly barriers inside the body, and with each barrier unlocked, one would possess the power of a true dragon. When all nine barriers opened, one could become a god in flesh.
