Don't Let Me Stay Up All Night

As everyone knows, there is a power in the southern region that absolutely cannot be provoked—the Grass Hall. 
The eldest disciple is the Sword Saint of the southern region, with a godly understanding of swords. 
The second disciple is the Eternal Empress, who ruled an era. 
The third disciple is a great scholar of the current generation, the reincarnation of the immortal of literature. 
The fourth disciple is the reincarnation of a demon god, suppressing the Nine Hells. 
Lu Changsheng: Me? I'm nothing special, just their master.

I See the Aura of the Great Emperor in All My Disciples

Lu Changsheng stood under the Nine Netherworld Formation.

"I wonder when they'll call on me again…"

Previously, it was just a projection. Next time, the power they would send over would be even stronger.

At that time, could the Nine Netherworld Formation still withstand it? What if he couldn't block it?

No, I cannot allow that to happen

Lu Changsheng began to study the Nine Netherworld Formation, wanting to see if he could improve it further.

The little chick didn't understand what Lu Changsheng was doing.

Only the willow tree knew Lu Changsheng's purpose.

Improve the Nine Netherworld Formation?

This was an ancient killing formation!

It was of extremely formidable strength. It was probably as difficult as ascending to the heavens to modify it!

Lu Changsheng sat in the air and rubbed his chin.
