If you keep playing, the upper limit is really 4000, but if it is a trumpet, the upper limit starts from the beginning of the season. This is also a catch-up method for trumpet and AFK to return to players. Of course, people who have been playing PVP have not made rapid progress. This mechanism was added in the last version 5.2, and the slogan was put forward from then on.

In other words, if I have a trumpet, I can directly ask them to help me fight for more than 10 thousand and buy half-length equipment.
