Chapter 900: System Mission, Defend the Realm Wall

This was a sign that the realm barrier was on the verge of shattering.

The appearance of the crack changed everyone's expressions.

If the demon beast race could enter the Floodgate Realm physically, the difficulty of the battle would undoubtedly skyrocket, multiplying the challenge several-fold.

Given the physical prowess of the demon beast race, even if the human cultivators could win, the losses would be grievous.

"Husband, the protective array has been set up!"

An array disk, radiating mysterious light, flew from afar and was caught by Jiang Chengxuan.

At this critical moment, Shen Ruyan had timely completed the setup of the protective array with her team.

"Good! That's very timely, wife."

Jiang Chengxuan let out a sigh of relief and joyfully responded.

He merged his Primordial Spirit into the array disk, and a perfect protective array emerged in his mind.
