Chapter 819: Essence Energy Compression Accelerator

In the huge warehouse-like laboratory, there was a strange device placed horizontally. It looked like a rocket launcher that could be held over the shoulder.

However, this thing was just too big. It was placed horizontally, and it almost spanned across the entire laboratory. Furthermore, it looked even more high-tech. There were circles of crystal rings on it.

In short, it was a rod-shaped object that combined metal and crystal.

"Are these all made of Essence Gold? The crystals on them should be Essence Crystals, right?" Zhou Wen asked in surprise.

If this thing was really made of Essence Gold and Essence Crystals, the amount of materials needed was unimaginable. Zhou Wen had a lot of Essence Crystals, but they would only take up a small portion of the huge machine.

"59% is Essence Gold. 28% Essence Crystals. The remaining consists of supplementary materials," An Sheng said.
