If he had it, during the day, he could constantly absorb the natural energy from the surroundings and refine it into ether energy. His healing rate will increase by ten times.

As Alina was as strong as 7-circle during the night, he was sure that no one would detect her whether she meets Feng Wu, assassinate his enemies, or even rob the treasury.
