At this moment, Hillena is studying the latest intelligence on the Helius Mausoleum.
This intelligence was hard-earned, brought back by several Grave Digger Teams after sacrificing dozens of lives.
The main content of the intelligence pertains to "Shell Syndrome." Some of the survivors who emerged from the mausoleum seemed to have their spirits and consciousness stripped from their bodies, leaving only a zombified shell.
Hillena's subordinates have already researched this issue and concluded that tools made from specific Sealed Objects might effectively resolve the problem.
However, relying merely on these to fully conquer the Helius Mausoleum and unravel its mysterious rules is far from sufficient.
Thinking of this, Hillena couldn't help but furrow her brows.
"Your Highness, there are two letters."
At this moment, a maid hurriedly entered the room, carrying two letters, placing them in front of Hillena, and her eyes inadvertently glanced at one of them.
