They are greedy, they are vicious, they do anything. This is the underground city that everyone in the above world fears and hates. … The dungeon numbered 444 was once a nightmare for creatures on the ground, a devil's cave passed down by bards, and a thorn in the side of the kingdom's temple. However, this legendary underground city owed huge debts due to the "poor management" of the previous city owner, which eventually fell on the descendants of Shen Yue. Shen Yue, who was tricked by a contract letter from an unreliable ancestor that fell from the sky, came to the underground world and inherited an underground city with a debt of 30 trillion yuan. Shenyue originally wanted to destroy her, but her ancestors were not humane. Not only did they leave her an empty dungeon with only mud houses, they also sold the lifespan of all their descendants to unknown beings. With only one year left to live, Shen Yue had to cheer up, regroup, develop and build underground cities, launch attacks on the above-ground world, plunder their resources and wealth, and harvest their strength and lives to nourish their own underground cities. For this reason, Shen Yue reached out to his native world. Lost a loved one, terminal illness, inadequacy, lifespan is about to run out, born evil... As long as humans ask for it, they can turn into the sharpest weapons under the gods. Be afraid, creatures of the earthly world! Welcome the arrival of the Great Demon King Shen Yue! !
