This was a counter-espionage tactic Ren Zhong learned from the Empire Intelligence Bureau under Duke Wenle.
There was no trick, and it was exceedingly simple.
The backbone of the Red Blade Army's reliance lay in the features of the Sublimated system.
Under genetic control, the Reproductive Subunits almost had no possibility of betrayal.
Indeed, Hmm Wei Wu didn't betray the Sublimated ones; instead, it acted as a spy by the enemy's side.
As a spy, it had to transmit information, and the details provided to Hundred Emperors by Hmm Wei Wu were indeed genuine.
However, with its capabilities, it couldn't know the real strength of the Red Blade Army now, so it only agreed with Hundred Emperors to assist with positioning when needed, which made sense.
Anyway, Hmm Wei Wu had already exhausted all its efforts.
