The Heaven Traversing Eight Saber is a technique from a very archaic era that once belonged to the Martial God. It displays its ultimate power when is used in combination with the Tyrannical Immortal Saber.
The Heaven Traversing Eight Saber consists of eight variations:
- River Crossing First Slash (一刀横江): A slash that cuts across the sky like a torrential river. 
- Hatred Aqua Second Slash (二刀恨水): A saber that covers the sky without leaving any openings.
- Void Circle Third Slash (三刀无环): A slash that comes out as a flash with unparalleled speed, capable to take down the sun and moon in the sky.
- Overlord Fourth Slash (四刀霸王): A slash with an indescribable might that had the power to flip over mountains and shatter the world.
- Heaven Traversing Fifth Slash (五刀横天): A slash that can seal heaven and earth.
- God Slaying Saber (六刀屠神): A variaton that causes the saber intent to go completely wild, cutting down everything in its path.
