Li Yi transmigrates into the Qin dynasty as an alchemist, and the moment he opens his eyes, he blows up Lanchi Palace. Faced with the First Emperor’s murderous intent, he remains calm and claims it was a “tribulation on the path to completing a ninth-grade pill.” He passes off his failed alchemy as an immortal pill on the verge of completion, and says his horse-faced colleague sabotaged him out of jealousy. Ying Zheng is skeptical, but this modern man who keeps going on about being a “ninth-grade alchemist” becomes the Great Qin’s only hope for making pills.
