The Light Forces are making good progress with clearing of the etheric plane, and some good news regarding that are expected soon.

Physical biochips are much more problematic, at least a this point. They are the main tool of surveillance through which the Chimera controls the surface population:

Those biochips would detect any physical intervention of the Light Forces on the surface. The contacted individual would first be very happy, but his increased vibrational frequency together with the video/audio feed from the biochip would alert the Chimera mainframe computer in the DARPA pit.

Immediate action would be taken to decrease the vibrational frequency of the contacted individual, either by removing that individual through DEW electroplasma induced heart attack, by orchestrating a car accident, by removing the loved ones of that particular individual, or by any similar means. This is one of the main reasons why the Light Forces are not contacting individuals on the surface.

If non-physical contact is made, or if a certain individual raises his vibrational frequency too much, the physical biochip detects that also, and automatically lowers the vibration of the individual by inducing electroshocks through the navel biochip. The navel biochip is capable of producing electroshocks between 20 and 130 volts, depending on the circumstances. At the same time, the two biochips in the frontal lobe of the brain produce strong magnetic fields that produce sleepiness, brain fog and confusion. Thus physical biochips represent a very efficient slave driver mechanism which controls the surface population.

The physical plane is further monitored and controlled through scalar network created with cellphone towers, cellphones themselves, and wi-fi networks:

The next layer is the global network of ionospheric heaters:

And the next layer is the Space Force surveillance network, which detects and removes any Positive ET intrusion attempts into the quarantine:
