Without the help of the Poison Pit Dungeon to deplete his satiety, Wang Wu could only switch to gluttony mode, from a feast every three days to once every four days, still accumulating at least 2,500 points of Spiritual Qi each time.
Thus, on the sixteenth day, he successfully upgraded his Passive Concealment to Level 15.
The Spiritual Qi consumed amounted to 12,500 points.
At the same time, at least half of his food reserves disappeared.
At this moment, lines of information silently appeared, still in the usual nagging mode, which Wang Wu found endearing.
"Because you remained motionless for three seconds, you activated Level 15 Passive Concealment."
"You have gained stronger understanding of the Inner Breathing Technique, you can naturally control your breathing, your heartbeat, your body temperature, and the dense, almost tangible vitality within you. This is the toughest problem of all concealment techniques, but to you, it's just a mountain you've conquered."
