When he wakes, Ying Chen’s ordinary life falls apart completely. Impostors are hiding in the city, undercurrents churn through the spirit realms, and he turns out to be the chief heir of the Qin bloodline left behind by Qin Shi Huang!
He encounters Zhuge Qing as his bloodline awakens, discovers that all three of his roommates are young heirs to families that guard the boundaries between worlds, and is soon approached with a recruitment offer from Institute 507. Clues to his grandfather’s disappearance point to the heart of the spirit realm, while the Evolution Divine Cult reaches its claws toward his loved ones. Onmyoji from Sakura Country and dark mages from the Dark Council also enter the fray. To protect his family, he sets out on the path of cultivation: drawing in qi, building a foundation, forming a core, and transforming into a nascent soul… The dragon qi of the Qin bloodline sweeps away the impostors, while the dragon qi of the Nine Provinces fortifies the boundary between worlds. With Zhuge Qing’s deductions and his companions fighting at his side, he goes from resisting his responsibility to taking it upon himself.
When the Impostor Lord tears open the barrier between the two worlds, technology fails and the entire population awakens. Ying Chen merges with the will of the surface world and breaks through to the Boundary-Guarding Realm. With the shadow of the Tai'e Sword, he suppresses the evil thoughts in the spirit realm. At the brink of the two worlds’ collapse, he finally brings about reconciliation, restores the balance of yin and yang, unites the spirit realms, and ushers in a new age of superhuman abilities for all! This is a thousand-year legend of guarding the boundary, about inheritance, protection, and heroic passion!
