"Proficiency +1"
"[Gravity Etching] Level 2 (100/100) → [Gravity Etching] Level 3 (0/100)"
"Perception +1"
Xia Nan's gaze swept imperceptibly over the translucent words floating in the empty air before him.

Compared with [Tooth Hunt], which, before it had reached max level, had required a huge amount of time each day, but at least reflected all the effort he put in as proficiency;
and compared with [Gravity Control], which would not budge no matter how he trained, only occasionally granting him one or two points of proficiency like an act of mercy when he had an "epiphany" or stumbled upon some "small trick";
[Gravity Etching]'s special nature—charging once every six hours and allowing at most three consecutive uses—meant that if Xia Nan wanted to raise this Combat Skill as efficiently as possible, he had to set a biological alarm clock.
He had to precisely grasp its six-hour charging time.

If he was in the middle of a mission, the training model had to be adjusted accordingly.
At first, Xia Nan had only felt that [Gravity Etching] was too easy to train. Unlike other Combat Skills, it did not require repeated practice; he only had to train at the
