"Immortal… Immortal Slaying Sword Formation!"

Xingyun was dumbfounded.

After all, the Immortal Slaying Sword Formation was quite famous.

That was the first ancient sword formation!

It was a top-notch killing formation controlled by School Master Tongtian.

Although it had disappeared after the God Sealing Tribulation, its reputation was known to everyone in all three worlds.

Seeing Xingyun's shock, Jiang Li smiled and explained, "Of course this is not the true Immortal Slaying Sword Formation. A true Immortal Slaying Sword Formation requires a Saint to be perfectly unleashed."

"This one is only a version of the Immortal Slaying Sword Formation created by my master that simulates the original. Other than that, my master also created the Immortal Slaying Sword Formation Diagram.

"Although it's only the immortal artifact version, I don't think I need to explain how powerful it is, right?"

Xingyun nodded.
