This seems more like a cult execution site than a promotion ceremony.
Not far away, you can vaguely see a team of doctors prepared and ready. In the transparent containers, there are liquids emitting a silver light, with a large number of Mang Silver Souls gathered here to deal with any possible contingencies.
Bologue mentioned earlier that he didn't think he needed the rescue team—a joke of sorts about saving an Undead, which sounds less like a waste of medical resources and more like a dark joke.
The doctors also believe rescuing an Undead is meaningless, but they can prevent Bologue from getting lost in the Ethereal Realm to some extent, so they remain at their posts, on high alert.
Getting lost is a more terrifying outcome than death; Bologue would fall into eternal slumber, turning into a living corpse.
