During the job transfer ceremony, the time traveler Lin Ran looked at the only hidden talent bound to him [Necromorph Evolution], and instantly made the most correct choice! He originally awakened the S-level hidden profession "Blood Earl" that shocked everyone. But in full view of the public, he took the initiative to abandon it. He chose the "useless profession" recognized by the entire Internet - Necromancer! Due to the collapse of the passage to the Necromancer Realm, the Necromancer could only summon crotch-stretching crispy skeletons, and was known as a useless SSS-level profession. For a moment, the whole school laughed at him! The genius fell from the altar! The snobbish school belle's fiancée turned against her on the spot, and the Lin family issued a divorce letter, severing the family relationship! "Waste occupation? Cannon fodder?" Lin Ran smiled coldly, the world had no idea, Not only does his skeleton have no upper limit, it can also evolve infinitely! Ordinary skeletons are brittle? Evolution! The basic attributes directly surpass the Abyss BOSS of the same level, killing elite monsters with one strike! Few summons? Unlimited explosive troops! Hundreds, ten thousand, one hundred thousand... One person is a natural disaster of the undead! Soon after, the abyssal catastrophe came! Countless high-level career changers fell into despair and retreated steadily. Just when the human defense line is about to collapse, Lin Ran held the staff and stepped into the abyss alone! Behind him are hundreds of millions of god-level undead armies wearing heavy armor and covering the sky!
