After mastering the Immortal Sect's Martial Arts Palm of Kunlun to Level 40, Zhang Yu chose to improve his mental method next.
As he sat cross-legged in the quiet chamber of the Flying Boat, his consciousness had already entered the Spirit Realm, arriving at the Taiqing Realm.
Zhang Yu planned to use the time acceleration of the Taiqing Realm to cultivate his second mental method, the 'Infinite Heart Internal Dharma Body.'
This Black Technique enhances the speed of thought processing, allowing multiple uses of one's mind, and multiple layers of thinking.
At Level 10, one can multitask; at Level 20, it enables Fourfold Thinking. When Zhang Yu, in the Golden Core Stage, elevated the cultivation technique to Level 30, he achieved Eightfold Thinking.
