In terms of combat power, Lu Xuan was already at the peak of the human immortal realm. His comprehension of the laws of lightning and space was also at its peak.
To a certain extent, his combat power was comparable to that of a celestial immortal.
Above the human immortal realm was the celestial immortal realm. In Full Moon City, the celestial immortal realm was considered the peak of combat power. It had been many years since a celestial immortal had been born.
Compared to the human immortal realm, the advancement of the celestial immortal realm was a little more difficult.
When one mastered the first law and used the power of the law to advance to a higher dimension, it was the celestial immortal realm.
If one wanted to break through the shackles of the human immortal realm, one had to accommodate the second law. The two laws had to fuse.
Then, one could advance to the celestial immortal realm!
