A moment later, Su Yu spoke two words to the energy coin:
"Retraction!"
As Su Yu spoke, the surface of the energy coin seemed to flicker.
The energy coin is a crystal of pure spirit energy that, once created, constantly decays, unable to exist eternally.
The universe itself has a lifespan, let alone an energy coin?
By assessing the degree of decay, one can infer its "lifespan" and calculate its time of creation.
And just now, under Su Yu's power, the decay process of the energy coin "retracted" for a few seconds, returning to the state it was in a few seconds ago.
"Failed..."
Su Yu shook his head slightly.
Though he successfully "retracted" the energy coin, it wasn't true time retrospection.
This "retraction" ability was something Su Yu had mastered long ago; he was just manifesting it in this dream with his powerful spiritual telekinesis.
This so-called retraction was actually learned from Zhang Chenfeng's mechanical creations.
