Great Qin: Confucian Sword Immortal From the Start, Sign-In to Recruit the Eastern Depot

I transmigrated into the Great Qin dynasty as Ying Zheng's thirteenth son, only to be exiled to the northern frontier to fend for myself! I activated the [Empire Sign-In System]. Signing in at Hangu Pass rewarded me with the peerless Sword Demon, while signing in beyond the pass brought me the Eastern Depot's death warriors! The Moon Goddess of the Yin-Yang School tried to coerce me in a dream? That very day, I ascended to the realm of a Land Sword Immortal, with purple qi pouring over my head and ten thousand swords paying homage. It's time for someone else to rule this Great Qin!
