This formation is a Fourth-grade Array, and the required materials are all fourth-grade. At least before becoming a Nascent Soul Cultivator, it was very difficult for him to gather so many fourth-grade array materials.
Li Shiming sighed in his heart. Even as a major sect on the same continent, the former Shushan Sect was vastly different from the current Ten Thousand Beast Sect.
The former Shushan Sect's grand formation couldn't withstand even a Nascent Soul Ancestor's attack, not even for a short period.
But in the Ten Thousand Beast Sect, not to mention the Sect Formation, even the formation of this floating mountain could block a Nascent Soul Ancestor for a time.
Li Shiming also found that the mountain hovering in the air was not just a symbol of status, but it became the first line of defense for the sect, while also enjoying enhanced spiritual energy supply from the strengthened grand formation.
