Liu Ri remembered these symbols. However, he had been taught from a young age that "these symbols are meaningless," "they are a tactic devised by Great Grandfather to confuse the enemy and to consume computational power." Hardly anyone in the Burrowing Dragon Community would contemplate the meaning of these symbols.
Indeed, they did not need these symbols since their brains contained detailed records.
However, Xiang Shan deciphered these QR codes.
Just as if he understood the text.
This type of QR code was neither the common QR Code encoding of the past nor any kind of computer-oriented method. It wasn't text translated into another format.
It was "readable text" in itself.
Or rather, it was a special encoding directly aimed at the human brain.
Back in the latter half of the 21st century… it must have been when Xiang Shan was still a tycoon.
