The copper plate was trash, and Wang Chen could only place his last hopes on that Sumeru Ring.
He steadied his mind and picked up the ring, which looked unremarkable, and tried to inject a thread of mana.
The result was that he instantly opened the internal space of the Sumeru Ring!
Usually, for high-order storage magic artifacts like the Sumeru Ring, the owner would impose restrictions inside them for two reasons. One was to facilitate recovery if lost, and the other was to require anyone else obtaining it to break the restrictions in order to use it.
If the original owner had a high cultivation level and set up very strong restrictions, it was completely possible for the new owner to only be able to stare at it helplessly after acquiring it.
But even the strongest of restrictions cannot withstand the merciless passage of time.
Without an owner's mana to sustain it, the restrictions within the Sumeru Ring would gradually become ineffective.
