Celestial Sect elders confront Zack after a month with no breakthrough and demand the Energy Pills Yuna bought. They find he fed their rare grade‑two pills to his dog and angrily accuse him. Zack insists Spirit Herbs are plentiful, then quietly starts refining on the mountain. A celestial anomaly draws everyone as he produces extra pills. The crowd is stunned when he reveals grade‑five pills — a grade thought extinct — and even offers some for Yuna. The sect is left shocked and hopeful, forced to reckon with Zack's unexpected skill.
