i have accidentally change the baud rate of esp8266 to unknown number, what shall i do?

What do you mean ?

Are you using Arduino ESP or AT firmware ?

In Arduino sketch, it is up to you to define Serial.begin(<baudrate>); in your setup() loop.

If you are using AT firmware, your question should be "how to get rid of AT firmware"

Oh ! so, you are using AT firmware.
You probably need to erase the configs stored at specific location.
On most ESP, this command will do :
