In the past, Feng Hao wouldn't have known what a compressor was for, but since delving into mechanics, he had gained some understanding of the machines in the Mage World.
He had read about compressors in the jade slip books. Their primary purpose was to compress Low-Level Magic Crystals into High-Level Magic Crystals, though they could also process certain special materials.
What Xue Xiaoyun said served as a good reminder.
To be honest, with his genetic activity at 48 points, he really did need a compressor. It would become absolutely essential, especially after he reached the fifth rank.
After all, Magic Crystals at Level 5 and above rarely circulated on the market. There were only two ways to get them: from high-concentration Magic Crystal Veins or by producing them with a compressor.
The former was a matter of sheer luck; some people went their whole lives without finding one. The latter, however, was far more accessible.
