Underworld Department 12-336 Classroom was located in Building No. 12 of the Underworld Department.
Besides players like Gu Xi, who had mastered the Three Divine Skills of Death, many ordinary Necromancers attended classes here as well.
After entering Building No. 12, one would find that many of the Necromancer players here had lost the flesh from their faces, exposing bare Skeleton faces.
Some players had even embedded various things into their skulls.
Some had gemstones embedded in them, some had gears, while others simply left their skulls cracked open.
There was every kind imaginable.
Having come here many times, Gu Xi understood that these were players who had encountered no special opportunities and had embarked on the path of the Lich as early as level 10.
Although recognizing people by their skulls was the most basic ability for a Necromancer, these players still liked to decorate themselves.
The different things embedded in their faces might represent the paths they had taken, or perhaps their personal ideas.
In any case, since they had already given up their skin, they naturally stuffed whatever they wanted onto their faces.
When they saw Gu Xi arrive, they curiously sized him up.
After all, Building No. 12 usually held classes for players striving to become Lich Kings. Players like Gu Xi, whose face was fully intact and who looked like a living person, were rather rare.
Ignoring their scrutiny, Gu Xi confirmed the location and pushed open the door to Classroom 12-336.
As the classroom door opened, Gu Xi saw four normal-looking players sitting inside.
There were three men and one woman. Yin Qi shrouded them all, but two kept their Yin Energy restrained while the other two let it spill outward. It seemed they had made different choices when advancing to Underworld Master.
