Xia Ren wakes up to find himself transmigrated into Xu Fu, and right at the start, he pulls out an immortality pill to let Qin Shi Huang taste it. Not following the usual tropes, he is directly struck by lightning, and after death, he discovers the ultimate secret of the Great Qin: Earth is actually "Diqiu", fittingly a gigantic cage! After resurrection, he is interrogated by the First Emperor about the origin of the immortal medicine, and Xia Ren bluffs that it comes from the Immortal Domain, never expecting the First Emperor to slap the table and say: "That is the lost territory of Great Qin!" Thinking on his feet, he copies later-generation novel cultivation techniques for the people of Great Qin to practice, and never expects them to truly become immortals! From then on, Xia Ren leads Qin Shi Huang to hack through the cultivation world, with his target pointing straight at the supreme throne!
