What is the Beiheng Sword Formation?
It is a terrifying sword formation created by Su Beiheng combining True Qi Martial Arts with the Qianyuan Soldier Killing Formation , utilizing the power of the Holy Martial Stage.
Hence, Sikong Jing shouldn't only learn the Beiheng Yuan Ying Sword. The Beiheng Sword Formation is an absolute treasure, and since True Qi can combine with the Qianyuan Soldier Killing Formation to unleash the power of formation.
Then, naturally, it can also merge with other Soldier Killing Arrays.
Therefore, during this period, Sikong Jing comprehended more power from the Domineering Soul Soldier Killing Array.
He also merged the Domineering Soul Soldier Killing Array with the True Qi within him, making True Qi capable of forming attacks similar to the Domineering Soul Soldier Killing Array. And the formation before them is based on the Beiheng Sword Formation, thus initially creating the Domineering Soul Formation.
