Regardless of how Jiang Xingyi discovered them, a person's ability to compose music was definitely not something learned overnight. They should have some unknown works under their belts, but this person didn't have any.
One possibility was that they had used a different name before. When they signed Jiang Xingyi's songs, maybe they changed their name. That was why they couldn't get any information about this person.
However, the important thing was that they knew of all the talented composers. These people had also recently released new works. After excluding these people, there were no empty seats.
In addition, the completeness of Spicy Beef's works was too high. It was not on the same level as the current generation of composers.
Spicy Beef really was a mystery.
