The Celestial Tyrant Saber Technique was a derivative from the War Emperor's early research into the Prison Guardian Blade Technique. It was a Sword Skill he abandoned due to some flaws.
It barely reached the level of an Emperor Level technique.
Although it had many flaws, that was only from the perspective of a Venerable Level figure like the War Emperor.
On the continent, it would absolutely be considered a top-tier, powerful Sword Skill.
The difference between this Sword Skill and ordinary ones was that when cultivating it, one did not absorb normal Spiritual Qi. Instead, it focused on the Slaughter Qi within the Heaven and Earth Primordial Qi.
The Slaughter Qi between heaven and earth was extremely aggressive. Many experts could crush an opponent's spirit with their Killing Intent alone, defeating them without a fight.
When this Slaughter Qi accumulated to a certain point and suddenly burst forth, it possessed the power to sunder the heavens and shatter the earth.
