This was the crucial step in advancing to the pattern condensation realm.
When one's martial intent reached the sixth level, one would be able to sense the mysterious power of the natural laws and engrave it into one's body.
However, the mysterious power of the natural laws were extremely complex. It was easy to imagine how difficult it was to engrave it.
Usually, most cultivators could only engrave a portion of it into their bodies.
Of course, the higher the cultivator's comprehension value, the more of it they could engrave into their body.
Ye Xuan's expression was solemn. The power of heavenly lightning within his finger danced like a pen as it engraved the mysterious power of the natural laws in the sky.
Most cultivators were only able to engrave 20%, but this was not Ye Xuan's limit.
In the blink of an eye, Ye Xuan had already engraved 30%.
