Reborn as an Undead Boss but Started from Scratch

Thousands of years ago, the Necromancer led the undead army to sweep across the continent, but mysteriously disappeared at the last moment. Thousands of years later, a modern man resurrected his body and stood on the mainland again in the body of the necromancer. However, this undead craze still brings death and darkness. Is it something else? Although he traveled through time and became a big boss, he gained no inheritance. Even the little skeleton had to be made by himself. Lu Yu spread his hands, there was a call, but the call was not renewed!
