"I am invincible at Yumen Pass."
In truth, it can only be at Yumen.
Abandoning one's path to becoming a Sword Immortal, and being forever trapped in a city, just to exchange for a power comparable to a Sword Immortal's—is this worth it?
For most Sword Cultivators, they would definitely think it is worth it, and would be willing to make the exchange—of course, even if they were willing to exchange, they couldn't.
To achieve this, it requires a sky-high level of cultivation to modify the Ancestral Daoist Great Formation.
It also requires unparalleled formation expertise to reconstruct the Ancestral Daoist Great Formation and refine one's Life-bound Sword as the formation's core.
Within the Human Race, only Yu Canghai meets these two conditions.
Yu Canghai, undoubtedly the foremost in sword formations.
Yu Canghai can achieve this.
