The Principle of the 'Clam of Jiaotu' that brings about Qi Mechanism shielding effects, is somewhat similar.
However, on a subjective consciousness level, there is a hint of objectivity from the 'Clam of Jiaotu'.
Even when the adversary is not focusing on other things, the 'Clam of Jiaotu' can forcibly guide his subjective mind into a similar state, thus eliminating the presence of one's own existence.
Specifically, the mechanism sounds very circuitous.
Put simply, it's like dangling a carrot in front of a donkey.
The donkey, which initially didn't want to budge, would be led to unknowingly operate the mill in order to get the carrot.
Therefore, the effect of the 'Clam of Jiaotu' can be understood as creating an invisible carrot to attract the opponent's attention.
And that millstone is equivalent to the shielded body of Qi Mechanism, unknowingly being put into action. The donkey is not even aware of it.
