When Chen Jue had brought back the Sun Wheel, he had never imagined that it could resonate with the Sun, ultimately triggering a response and setting off a series of events, including a solar flare.
Only now, after using his microscopic perspective to see the "sun" character rune inside the wheel clearly, did Chen Jue understand how it worked.
So-called quantum communication used the phenomenon of entanglement between two quanta to synchronize two quanta separated by vast distances. Whatever displacement one quantum underwent, the other could undergo the exact same displacement.
In scientific circles, this technology was touted as a solution to humanity's future communications needs after entering space.
Radio signals traveled at an extremely limited speed and were very easily lost. They were more than adequate for transmission within Earth, but once people embarked on space voyages, this outdated communications technology would inevitably be phased out.
Quantum communication was different. Even across hundreds of millions of light-years, as long as the two entangled quanta synchronized, the information transmitted by the other side could be received quickly.
Put simply, if you held a pen and wrote on paper, another pen infinitely far away from you would write exactly the same words.
This Sun Character Rune should be some application of rune technology.
Like the First Emperor's Imperial Heirloom Seal, it also carries unknown information technology.
If I can fully master its principles, I won't have to worry about losing contact even after leaving Earth, Chen Jue thought.
By extrapolating from this one detail, he could already roughly deduce the technological level of the ultra-ancient civilization on Second Home.
It was an advanced civilization capable of opening spatial passages, destroying planetary surfaces, and using quantum communication.
Although he did not know why this civilization had left the Sun System, the clues
