You Li Ye Er opened with his ultimate move, rapidly converting Huang Ji into Dark Matter.
More precisely, into Tachyons.
There were many types of Dark Matter, divided into Dark Matter Elements, Soul Particles, Virtual Particles, and Tachyons.
Tachyons, as their name implied, were faster-than-light particles.
Because they exceeded the speed of light, they could not be observed. Most Star Realm Overlords had never encountered such matter unless they possessed Spacetime True Sight.
Furthermore, Tachyons could not store data. They could only carry energy, serving as the transmission medium for nearly all Dark Energy, corresponding to photons in the Bright Matter world.
It was worth mentioning that the greater a Tachyon's energy, the slower it moved. Yet it could never reach light speed—or rather... it could never slow down to light speed. That would require Infinite Energy. Tachyons could only approach light speed infinitely...
Conversely, the less energy they had, the faster they moved.
Because they carried all kinds of Dark Energy in faster-than-light motion, they caused spacetime to expand...
It could be understood as them racing back and forth across every corner of the universe at superluminal speeds, striking the universe's boundary barrier and stretching spacetime outward as though inflating it.
Whoosh! Huang Ji was transformed into a Tachyon body by You Li Ye Er.
With a boom, he exploded into countless invisible faster-than-light particles that shot toward every corner of the universe.
They were too fast, like wild horses breaking free of their reins.
Huang Ji's body was torn directly into pieces, scattering in every direction. Countless particles from his body traveled to the fringes of the universe and even made a round trip...
His existence added an utterly negligible amount to the rate of spacetime's expansion.
As for Huang Ji's soul, it remained where it was. Soul
