Chapter 59: Improving The Ancient Killing Formation

At this moment, in the Cottage.

Lu Changsheng stood under the Nine Netherworld Formation.

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

Lu Changsheng looked worried.

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.
