Chapter 680: Full-Scale Assault, Attacking the Central Plain

"Is this his ultimate fate after falling into demonic madness?"

Jiang Chengxuan couldn't help but frown.

Looking at Shang Heyun, whose demonic eyes were fixed on him and Shen Ruyan, both of them felt a sense of gravity. It wasn't that the demonized Shang Heyun posed any threat to them, but rather the changes in this world had exceeded their expectations.

It seemed that they could not wait any longer after this matter.

They had to wipe out all the enemies as quickly as possible.

Otherwise, without even needing the intervention of that entity from the outer world, the Nine Essences Cultivation World might collapse internally.

With this in mind, Jiang Chengxuan didn't hold back any longer.

He raised his hand and waved.

The Level 6 Pure Yang True Treasure, the Demoncleaver Spirit Sword, suddenly transformed into a brilliant sword light.

In a flash, it pierced through Shang Heyun's forehead.
