Chapter 823: I Haven't Used My Previous Strength in a Long Time

The Demon King landed on the ground with an awful face. "Close the gate of the Demon Realm. We can't let them out."

Feng Qingtian flew swiftly with Gu Bailu, trying to escape before the gate closed.

However, he was too late. The gate of the Demon Realm was firmly shut.

The gate of the demon world was a hundred meters tall and made of cold stone. No amount of force could break it.

"I'll find another way." Feng Qingtian led Gu Bailu to the other side. The gate was shut, but there were other barriers in the Demon Realm that could be broken.

Gu Bailu stopped him. "There's no hurry. Follow me."

She knew exactly where the holes in the barrier were.

In her previous life, she had basically familiarized herself with the entire Demon Realm.

Also, because of her unique family arts, she paid special attention to such barriers. Thus, when she came to destroy the Demon Realm in a fury in her previous life, she could do whatever she wanted.
