If it was about martial arts, Ye Yuan might be more humble. But as for alchemy, Ye Yuan really did not know how to be modest.
It could be said that Ye Yuan spent his entire past life busying with alchemy. He was simply too familiar with medicinal herbs and pills.
This sort of familiarity was engraved into the soul. Even if he changed his body, that sort of familiar feeling which came from the soul would automatically make the body carry out the most appropriate actions.
Originally, Ye Yuan wanted to be low-key. But once he touched those medicinal herbs, he could not help but to complete the preparation of herbs and refine the medicinal essence.
Others might be filled with trepidation towards measuring the quantity of the medicinal herbs and did not dare to carelessly leave out anything. But Ye Yuan just had to casually grab them with his hands, and the quantity of the herbs would definitely be accurate.
