Ding Fan knew that this ancient formula was not something that could be obtained casually. For an alchemist, acquiring an ancient formula was undoubtedly a stroke of great luck, but trying to restore this ancient formula was evidently the most painful thing for an alchemist. After all, restoring an ancient formula was extremely difficult, a fact all alchemists were well aware of.
The other party had spent half a year restoring the quantities of eighteen spiritual materials, which was already quite commendable. Ding Fan acknowledged the other party's alchemic talent but wasn't overly shocked. He remembered when he once restored an ancient formula with forty-eight spiritual materials, it took him about half a month back then, which clearly was already quite exhausting for Ding Fan.
Ding Fan deeply experienced that feeling, describing it as a pain mixed with joy, as the sense of achievement upon restoration left a lasting impression on him.
