The so-called Blood Killing Sword Array is a notorious, evil Taoist formation known for its simplicity in arrangement and powerful destructive force.
The principle of the Blood Killing Sword Array is simple; first, set up forty-nine foundation stones, then use the fresh blood of an innate martial artist to nourish the longswords inside these stones. Eventually, with the use of a secret technique, the longswords absorb all the fresh blood within the stones and transform into potent blood swords.
Once all these steps are completed and the Blood Killing Sword Array is activated, an overwhelming surge of blood will fill the Array, and the longswords, nourished by the blood of the innate martial artist, will unsheathe automatically. They will slaughter every living thing within the Array until their blood energy is fully depleted.
Originally, the Zhang family planned to lay out the Blood Killing Sword Array around the Du family before launching an attack.
