When a cultivator advanced into First Change, their blood would turn from red to purple, and when it became completely purple, he would have reached peak stage of First Change.
This was a very obvious characteristic.
And if the blood turned blackish purple, what did that mean?
Second Change!
At the end of the Second Change, the blood would turn black, and the process of Second Change was for blood to turn from purple to black.
Blood affected aura, so unless one had cultivated a special cultivation technique, the Qi and blood emitted would be the same colour as their blood.
Thus, Hong Tianliang had most likely advanced to Second Change. This also explained why his aura was so unstable.
This was what surprised Ling Han the most. This guy actually surpassed him in terms of cultivation level?
It should be known that Ling Han's advancement was already very, very fast. It was indeed surprising that he could still catch up to him.
