Chapter 109: Demon Invasion

After returning home, Chen An did not eat. Instead, he was busy studying how to set up the array formation.

Shen Qingyi didn't eat either and came out to study it together.

Both of them were Foundation Establishment Cultivators, so their need for food was already extremely small.

Many times, just breathing in and out the spiritual qi in the air could provide the body with sufficient energy.

"Alchemist Chen, how much did you spend on these two arrays?"

"One high-grade spirit stone per book costs a total of two high-grade spirit stones."

"That's quite affordable."

"Fellow Cultivator Shen, do you know how to set up these two array formations?"

"I know a little. I learned how to set up array formations in the Xuanhuang Sect in the past."

"…"

Soon, with Shen Qingyi's help, Chen An successfully set up the Cloudfall Array and the Lightning Strike Formation.
