This crystal was originally a fragment that had broken off a much larger crystal in the Tomb Star Realm. The deathly aura it contained could give S-rank death-attribute skills a chance to evolve.
It later underwent Shi Ming's infinite upgrades.
After its infinite upgrades, the Silent Crystal, though it still looked like the same dark shard as before, now possessed its full functionality.
By holding this item near the concealed First Civilization Cosmic Country, one could use the crystal's connection to the Tomb Star System to enter a state of silence, bypass the joint seal of the pseudo-gods, and return to the First Civilization Cosmic Country.
This Star Domain was complex.
If it was truly related to the Tomb Star Realm, it was bound to be monitored by pseudo-gods—and most likely more than one.
After arriving in this Star Domain, Shi Ming had maintained extreme secrecy and investigated many places.
Only here, for the first time, did the Silent Crystal show a faint reaction.
