Are You Kidding Me? Summoning Undead, You Contracted a Jiangshi General!

Hell stands empty—every devil now walks among us. In a world besieged by demons, humanity's last hope lies in contracting the undead. Most summoners settle for C-rank cannon fodder like Skeleton Warriors and Zombies, while the lucky few command B-rank Undead Knights or even A-rank Bone Dragons. But on Contract Day, transmigrator Wang Yu shatters every expectation. His unprecedented talent attracts not one, but multiple S-rank undead—including the legendary one-in-ten-thousand Bone Dragon King. Yet his true ace? An ancient Jiangshi General whose power defies all rankings!
