The Beiheng Origin Shadow Sword was a sword technique Su Beiheng had created himself by merging the Qianyuan Battle-Killing Formation within the first One-Claw Domain. Aside from his battle against Pei Kuang and Madam Raccoon, and the five swords that pierced the Six-Clawed Evil Heart Hybrid Beast, it had never appeared before!
Naturally, it had no name, so Sikong Jing gave it one.
The word "Origin" came from the Qianyuan Battle-Killing Diagram, while "Shadow" came from the unending waves of sword shadows, together with Grandpa Su's name.
And Sikong Jing naturally knew that although this sword technique had never undergone any testing, it was absolutely Saint-grade. Compared with the Saint-grade martial skill within the stone-pier Heavenly Pattern Treasure Artifact he had obtained, it was only stronger, not weaker.
Once cultivated to its peak, it would likely reach the level of a top-tier Saint-grade martial skill.

Sikong Jing murmured again, "It has also opened the door for me to merge true qi with battle-killing formations. If I obtain stronger battle-killing formations in the future, I can continue merging them and push the Beiheng Origin Shadow Sword to the level of a God-grade martial skill."
