One can imagine how much destructive aura is contained within this strange crystal core, as Zheng Yi only took a glance before pulling out a jade box to store it away.
Then he cast over a hundred sealing spells on its surface, firmly locking it shut.
Although it's unclear what exactly this thunder core is,
it undeniably contains a terrifying power within its essence, enough to threaten the strength of a Nascent Soul True Monarch, which means this item is extraordinary.
Perhaps it's not needed now, but there might be a time when it comes in handy.
Of course, such a dangerous item, if not stored carefully, would cause a disaster if accidentally activated.
So even as Zheng Yi placed it down, he was extremely cautious.
After casting countless sealing spells, he felt relieved.
No one would ever say they have too many treasures like this.
You never know when something like this could save a life.
Shua!
