The emergence of a spiritual sword broke the seal on the Blood Demon and allowed him to reappear. This spiritual sword also caused a bloody storm in the world. The owner of the spirit sword was forced to commit suicide to protect his family, but he used the method of scattering souls to nourish his soul and put his seven souls in the spirit sword, which caused the blood demon to be severely frustrated and possessed a mortal body to linger on. The earth was temporarily peaceful, and the spirit sword was buried underground, waiting for the birth of its owner. A thousand years later, the masters of the seven spiritual swords were born, and the blood demons were waiting for the opportunity. In order to obtain the spiritual swords and dominate the three realms of humans, demons, and immortals, they killed innocent people indiscriminately and did not hesitate to destroy the entire witch clan. The masters of the seven young men worked hard to bring them back to Zhushan, taught them the spells, and made the spiritual swords appear in the world. They trained themselves through tasks while looking for their relatives. In the end, in order to deal with the blood demon, everyone paid a heavy price, even their own lives.
