The Essence of the Dark Dream is a special potion made by the Polar Blood Alliance using Alina's blood during the Mage League, designed to induce sleep in mages and ineffective on ordinary people.
Most of the camp's inhabitants are mages, with only a few ordinary soldiers.
The ordinary soldiers are unaffected; putting the mages to sleep will achieve the goal.
The Essence of the Dark Dream was quietly released, quickly infiltrating the camp.
The mages here have much lower resistance than the participants of the Mage League, and soon a group of mages yawned uncontrollably and quickly raced to sleep, leaving the ordinary soldiers to stand guard.
This situation left all the ordinary guards bewildered.
They felt something was off but, not understanding the mages' methods and lacking the authority to inquire about their condition,
had to take over the duty of night watch.
Fortunately, the night watch mostly consisted of ordinary people, with only a few mages assisting.
