Defrauding the World, Loading the Emperor Engine at the Beginning

He accidentally traveled to a new world, awakened as a necromancer, and was about to face the test of heaven. Just when Xu An was worried about his low strength and being unable to pass the test, he obtained the Emperor Engine System. Inherited from King's mysterious system, strength no longer requires fighting to improve, it all depends on the enemy's imagination. As long as everyone believes in himself, all power can be embodied in him. From then on, only Xu An's legend and achievements were left in the world. "I changed my job for the second time so soon. Is the Necromancer so strong?" "Whoever believes this is stupid. Let me tell you, it must be a hidden professional lich." "Lich? Isn't that capable of transforming endless undead creatures?" "Your lich can transform endless undead creatures, at least it is a profession like the Undead King." "Isn't it? King of the Undead? This has to be a third-level profession, right?" Meeting the dissemination conditions, congratulations on switching to a new profession - Undead Monarch, and gaining SSS level talent... This novel and its characters are purely fictitious.
