章 899: Visualizing the Thundering Prison

With the help of the Great Pagoda, Mu Chen was able to refine 20,000 Meteorfall Alchemy pills without fail. The most reassuring thing was as long as the pagoda was powered with spiritual energy, it would be able to refine automatically. He did not need to keep an eye on it, which in turn saved him a lot of time.

He could make use of the extra time to study the "Nine Calamity Thunder Prison Visualization" scroll, which he had found in the Death Relics.

Even a Grade Six Sovereign would be jealous of the thick smoke lingering in the cave that contained a huge amount of spiritual energy essence.

Meanwhile, Mu Chen was sitting quietly in the cave. His body was covered in clouds of smoke, but his expression remained unchanged. He sat there like a stone, not moving at all.

After he entrusted the task of refining the Meteorfall Alchemy to the Great Pagoda, he immediately drew out the Nine Calamity Thunder Prison Visualization scroll from his memory.
