The Seal of Heaven is an Immortal Artifact at the Immortal Venerable level. It appears to be only the size of a fist, but Fang Bai knows that once it strikes down, it will magnify a thousandfold, even ten thousandfold, akin to a mountain descending upon one's head, making it difficult for even ordinary Immortal Venerable level experts to withstand its blow.
"That Immortal Artifact is even better than the one I refined for you earlier. Do you want it? If you do, I'll help you get it!"
Fang Bai cast a glance at the Seal of Heaven above Xuankong Immortal's head and asked Tu Mo behind him.
Tu Mo was momentarily stunned, then let out an "ah" and opened his mouth, unsure of how to respond.
Subconsciously, he felt Fang Bai was joking with him, but with such dire circumstances at hand, where life and death hung in the balance, such a joke was not something he could laugh off.
