They operate on a shift system, with each shift consisting of a thousand Foundation Establishment cultivators. A thousand-strong Foundation Establishment battle formation is sufficient to defend against a late-stage Golden Core cultivator like Yinuo Nianhua.

The so-called late stage of Golden Core, when converted into a player's cultivation level, is actually level 6 to 9 of the Golden Core stage on the player's stats panel.

Levels 1-3 are the early game, levels 3-6 are the mid-game, and levels 6-9 are the late game.

A level 9 reading bar at 99% is what's known as the peak of the Golden Core stage, which is easy to understand.

The power unleashed by a thousand Foundation Establishment cultivators launching a battle formation is roughly equivalent to the late Golden Core stage.

That's enough to keep Yinuo Nianhua occupied until the two Golden Core stage cultivators arrive to provide support.

Moreover, they had already driven Yinuo Nianhua away, and even severely injured her.

Therefore, the monks on duty are now very lax.

That kind of injury would take several months to recover from.

They were either cultivating themselves or refining magical artifacts; they were simply doing their own thing.

However, to the surprise of the cultivators of the Immortal Spirit Continent...

A few days later, the portal suddenly opened!

This was quite sudden!

That guy is back again!

"Notice!!!"

Meng Lu, the Foundation Establishment cultivator in charge of the duty shift, noticed the fluctuations in the teleportation portal and began to issue a warning.

Because his perception was the strongest among Foundation Establishment cultivators, and it was because of this characteristic that Zhao Retian chose him as the person in charge of the Foundation Establishment battle formation.

"Portal fluctuations!!! Everyone on alert!!!"

Meng Lu swiftly used magic to awaken all the Foundation Establishment cultivators in the battle formation, rousing them to their senses.
