The stronger Han Zheng's power, the more cautious he needs to be with each breakthrough. Ideally, each breakthrough in cultivation techniques should complement his existing techniques.
After pondering for a while, Han Zheng decided to break through the True Martial Nine Yang Holy Body and the Black Heaven Tathagata Demon Buddha Form.
The former mainly cultivates the physical body, which has always been Han Zheng's primary path.
The latter is the main source of Han Zheng's power techniques and should be prioritized for breakthrough.
Upon reaching the True Pill Realm, Han Zheng gained a deeper understanding of his Martial Arts path.
As long as he accumulates enough power, even a casual strike could have the power to topple cities and shake the earth.
For the Black Heaven Tathagata Demon Buddha Form, it was simple enough; Han Zheng used fifty thousand Hunger Level to elevate its Skill Level to Perfect.
