Her superpower is indeed special. If these people find a suitable Mutant Beast, and Wu Ke helps to calm the beast's emotions before the contract, the success rate of the contract will be much higher. As a result, more people are tempted.
However, only those who have enrolled in the class can enjoy this special service. With this limitation, those who originally planned to save crystal cores by having one person listen and relay the information to others have no way to do so. After all, even if they attend the class, they only gain some understanding of Mutant Beasts. It doesn't guarantee contract success, whereas Wu Ke's help is more reliable.
As a result, Wu Ke has earned quite a few crystal cores. Coupled with the dividends Fang Yuxin insisted on giving, she has even more crystal cores now.
