Tianyuan Continent uses sword fetuses as the foundation for cultivation. The sword fetuses are divided into nine grades. One grade is respected and can use the swords of heaven and earth for one's own use. Those with mortal fetuses will crack the tiger's mouth even if they hold the sword, and they are destined to have no chance of practicing.
The Qingxiao sword family has been silent for a hundred years, but a "mortal waste" Lin Qingxuan has emerged - he was born with a ninth-grade sword fetus. At the age of five, he broke into the sword tomb and was penetrated by half of the rusty sword. He has become the laughing stock of the family ever since. For ten years, he used his essence and blood to warm the residual sword in his body. On the surface, it was still a mortal body that could not hold the sword. In fact, the residual sword had already swallowed up the centuries-old sword energy of Qingxiao Mountain, and quietly condensed into the "Tian-Slaying Sword Fetus" left behind by the ancient sword god.
During the sect competition, he used his wooden sword to receive three moves from the elder of the first-level sword embryo. When the sword embryo awakened, the black sword energy shot straight into the sky and shattered the mountain of spiritual swords. In the Tianyuan secret realm, he fought alone against the geniuses of the seven realms, using his mortal body to inspire the inheritance of the ancient sword domain. When the sword pointed at the sky, the sky-cutting sword embryo manifested its divine form, and the sound of the sword shattered the clouds thousands of miles away.
A mortal who was regarded as an ant decided to use the remains of the Sword God as a blade to prove to the spiritual world where swords determine life and death: mortals can also kill immortals, break realms, and master the sword rules of heaven and earth!
