Undead: I Am Forced to Be the Boss Behind the Scenes

(The protagonist will not be able to transform into other forms, which is extremely mainstream. The protagonist will not have fighting ability, and there will be no scene where the protagonist goes up to fight!) Mo Guli died and lived again. When he woke up, he became a black robe among the ruins of the undead world. He had no strength, no body, and even his existence itself was in danger. Until he was clothed in the undead - power seemed to appear. Not only that, he discovered a secret: by absorbing the dissipated undead, he could inject power into other undead, allowing them to evolve, break through, and even awaken to their powers in life. Then, a figure always wearing a black robe began to wander between the battlefield and the cemetery. Other undead monarchs relied on fear to rule their subordinates, but he relied on making each of his subordinates stronger than before. As cities were swept away and regions conquered, the outside world still didn't understand who the leader of this team was.
