As a member of the Age Candle Immortal Court, Han Yi had an obligation to accept the mission to travel to the Emperor Fallen Sky Pond.
However, his realm was previously unstable, so he could not leave temporarily.
Now that his cultivation had stabilized and his strength had increased, he naturally needed to fulfill this duty.
Speaking of which,
as a member of the Age Candle Immortal Court, his contributions to the Immortal Court weren't significant. In fact, the Immortal Court had been providing him with resources for cultivation, especially through the channel of the Void Tower, which constantly awarded him with Immortal Marks.
With his recent rise from the fifteenth to the third rank on the Golden Immortal List, the Immortal Marks alone amounted to thirty million, which was enough for a Profound Immortal at the peak level to cultivate to a Peak Golden Immortal.
