Roye Lei's specialty.

A mathematical genius, he is very sensitive to numbers and good at mental arithmetic and quick calculation. No matter how complicated the calculation process is, he can work out an accurate answer in the shortest time, with the accuracy reaching the third place after the decimal point. At the same time, he has a good ability to read quickly and never forget anything, and his memory is super strong. People, things and things he has seen will be remembered even after a hundred years. He is also a natural investment and financial expert, especially good at all aspects of investment: stocks, futures, gold, bonds, real estate and so on. And he knows everything. In addition, he is also good at "money laundering" and can "change" a lot of money without a trace.

When I was a student, I was the chief financial officer of Dong Bang, and sirrah's requirements for partners (related to discounts) were decided by Fan Jun. Fan Jun's accurate analysis (including the personnel distribution and topographic features of the purchasing place) is enough to explode the FBI.
