According to scientists, this type of twin-particle quantum entanglement communication technology had already surpassed what a Third Level Cosmic Civilization could master. Without the cosmic string oscillations data under extreme spacetime curvature, this technology could not have been achieved.
Humanity happened to have data for the extreme conditions near the black hole event horizon, and with a computation period exceeding ten thousand and three hundred years, they were able to cross a civilization level and create this communication device.
Lu Yuanming was unclear about the specific manufacturing mechanism. He only knew that scientists simulated string information through strong energy fields, inputting information into two particles in a state of quantum entanglement, similar to programming a process.
