Yi Beidou fused with the True Intent of the Nameless Sword Lord within the Silent Heart Sword, reviving it within his own body and creating a second personality. He allowed this personality to control his body, learning its Dao and Skill. He even integrated a portion of the Nameless Sword Lord's Evil Qi into himself, making his own Celestial Demon Evil Qi even more potent.
In a short time, he used this to create the killing move, Destruction Killing Tribulation.
This Technique appeared powerful, but in reality, it was not yet perfected.
The True Intent and Evil Qi of the Nameless Sword Lord were a minor path. Although integrating them into Yi Beidou's own Celestial Demon Evil Qi strengthened it, it also made his Heart Intent impure.
This was unavoidable.
