Jade Cream was a scar-removing Spiritual Medicine that Shen Qiang refined using Mo Yunzhi. To explain this, it's both simple and complex, but if we set aside the concept of Cultivation, it can be summarized in one sentence.
"It's a kind of rare medicine," Shen Qiang briefly explained.
Sun Kaiping nodded, "No wonder it's so valuable."
Boss Ma laughed and said, "Qiang is really impressive, being able to do business with medicines. It's just a pity that in this field, the two old guys like us are really laymen, and with our age, I'm afraid it's too late to learn."
Shen Qiang smiled, "Nobody knows and can do everything. Being at the top of an industry is far better than someone like me who dabbles in everything, yet is only average in all."
The two men laughed.
