Code: [Select]
now it make sense that i have 6.5V on the cpu
No, that still doesn't make sense. There is a regulator on the board. Only a very smal part of the board should have more than 3.3V on it.
and what about the signal going free through 3.3v and gnd with the tester?

Did you use the right polarity? Some parts have very low resistance reversed. A booting ESP might take enough current to make your tester beep. It might test continuity by applying the voltage directly from a 9V block battery, because of which using it on an IC is a superstupid idea in general.

Sorry, but honestly: You seem to have no idea what you are doing, it is not even sure if you measure correctly. You also keep ignoring the only measurement that makes sense.
