Immediately afterward, an astonishing scene unfolded.
The ghostly mist all around them suddenly began to recede. At the same time, the heart-pounding sensation from beyond the rift vanished, as though it had been cowed by the azure light!
With these two layers of seals, the passage was finally sealed off for the time being.
Next, Zhou Xun took out the Ninefold Echo Grand Formation and set it up.
Thus, even if this passage were reopened, with this formation here, they would be unable to break through it in a short time. This would give the cultivators of the Westplain Cultivation World time to react.
After finishing all this, Zhou Xun flew out of the valley.
At this moment, Blackwind Old Demon was waiting anxiously at the entrance.
Zhou Xun had been inside for several days without emerging. He feared that something had gone wrong, yet he did not dare enter rashly.
After all, Zhou Xun's strength was plain for all to see. If even Zhou Xun had become trapped within, going in himself would merely be delivering his life into the jaws of death.
Just as he could wait no longer and was preparing to leave and report to Perfected Lord Yunku, he finally saw Zhou Xun flying out.
"True Lord, how did it go?" Blackwind Old Demon hurriedly asked.
"I did not fail my mission." Zhou Xun smiled faintly.
"That rift has been sealed by me. They should not be able to enter again anytime soon, but the remaining two high-grade formations still need to be set up."
"I fear that the Ninefold Echo Grand Formation alone will not hold back the ghost clan for long. If we can have three high-grade formations—"
"Later, I will set up a Teleportation Array here. You should assign people to keep watch.
