In this chapter, we learn that the god slaying technique is extremely powerful, but that doesn't stop it from being overpowered by the ultimate speed of the sword. This is because the sword is made up of chi, the "master of all weapons" , and the power of the weapon is accumulated through chi's mastery of the weapons. The only way that the sword can be defeated by defending is if the opponent is using a "minimal sword technique" . This means that the opponent must use a "hidden momentum" to defeat the opponent. This "momentum" in the opponent's sword seems to be the same as the momentum in the sword of the Master of All Weapons . It takes three years for the master to master the primal sword technique, but it only took him 300 years to master it.
