Mo Hua took some time to inscribe the Gold-Cutting Sword Formation inside the Spirit Sword.
Unlike the sword formations used by the Sever Gold Sect for forging swords, the Gold-Cutting Sword Formation that Mo Hua inscribed within the sword was a self-sustaining complex formation system with a spiritual power cycle.
Ordinary Gold-Cutting Sword Formations rely on a cultivator to supply spiritual power to amplify sword qi.
But Mo Hua's modified Gold-Cutting Sword Formation altered the formation's structure and added a Spirit Gathering Array as the formation's eye.
The Spirit Gathering Array would pre-charge spiritual power for the Spirit Sword, and the spiritual power would undergo transformation through the formation, converting into sharp Gold-Cutting Sword Qi.
Using Spirit Stones to supply spiritual power instead would eliminate the dependence on personal spiritual power.
Mo Hua's spiritual power was weak, and he couldn't afford to use powerful sword techniques.
