This is the iron law proven by countless Sword Cultivators throughout history!
Therefore, Zhou Chun couldn't let his son act recklessly, and ultimately only allowed him to cultivate a top-tier technique that wasn't very strong nor very weak, called "Nine Revolutions Golden Light Art."
The cultivation of this top-tier technique is not as dangerous as "Golden Cauldron Profound Art," or rather, it basically poses no risk of deviation, but it especially tests endurance and aptitude resources.
After cultivating this technique, in order to break through the Foundation Establishment Middle Stage, one must use the secret technique to disperse most of the mana cultivated to the peak of the Foundation Establishment Early Stage, returning to the state just after achieving Foundation, repeating this three times to succeed; then from Foundation Establishment Middle Stage to Late Stage, Late Stage to Purple Mansion Phase, all require three repetitions as well!
