Su Yu suddenly received a particular signal.
This signal, is... a causality signal?
Outside the Little Universe, time and space do not exist.
But there is causality radiation, and the farther from the Little Universe, the lower the causality ratio.
From 0.99999... to 1, it gradually decays to 0.
As a Mechanic of Cause and Effect, Su Yu is very sensitive to the decay of these causality radiations, and any change cannot escape him.
But just now, those causality ratios fluctuated, becoming a kind of special signal, which is the phrase Su Yu just received, a "greeting" from Yi.
It was the first time Su Yu saw the use of causality ratios to transmit signals.
Su Yu could also achieve this method, but had never tried or seen it before.
This Yi guy, truly deserving of being a veteran Cosmic Undead, has many tricks.
Seeing Yi's greeting, Su Yu did not respond immediately, but cautiously activated holographic perception to locate the signal source.
