Everyone Changes Jobs and Awakens the Necromancer at the Beginning

[No pressure on combat power + no brains + no cp + melee mage] [The big stage of all races, don't come if you're not here, and don't come if you're not! [In the early stage of the battle, the mage has few attributes, after all, plug-in skills have to appear one by one] The two worlds collided, the real world turned into a game, and mankind entered an era where all people changed jobs. Monsters invaded the world, and many collision nodes caused time and space to become chaotic, giving birth to countless copies and secret realms. Death and freedom! Danger and opportunity! Only by constantly fighting, constantly upgrading, standing out from danger, and being reborn from death can we be worthy of freedom! Only worthy of talking about opportunities! The boss died? No, the boss obeyed my call and became my servant! I am the monarch of the undead, the only king of the world of death, and with a wave of my hand, the undead army sweeps across the world!
