The integration of strength could be achieved miraculously through one's own efforts, but what Zheng Yichen valued more was the unlocking of weapon and equipment enhancement.
With the harmonizing stone enhancement, the materials used for future enhancements could be unlocked directly. Even if a Life-type Godhead were acquired later, it could be used as enhancement material in weapons and equipment without affecting their performance.
Another key aspect was the attribute reversal of his weapons and equipment aside from the change in unlocking enhancement material types by the harmonizing stone.
This effect allowed his weapons and equipment to possess properties equivalent to double their normal, although some power reversals wouldn't show much change. However, properties with extreme attributes would indeed change--death, life, chaos, fire, ice, light, and darkness, and so forth. These could all be reversed.
Properties such as wind and thunder, however, would be disregarded.
