Da Qin I Am an Alchemist

Traveling to the Qin Dynasty with the sarcophagus, he is an old man with no system and only a small amount of modern common sense, but he is forced into the palace when summoned... "When you are thirty, you stand upright; when you are forty, you are not confused; when you are fifty, you know your destiny; when you are sixty, you are attuned to your ears; when you are seventy, you follow your heart's desires! I am seventy-nine, and I have nothing to pursue in my life!" "Okay!" ... "Qin, there should be black water true dragon flags all over the earth!" Ps: The background is from a Shinhwa fanfic!
