"So you've been toying with me all along."
The Nightmare Demon King gave a bitter smile. No wonder the Mechanical Demon King had dared to come to Nightmare Hell, no wonder he had been so arrogant. He was already at Single Universe Level. This defeat had not been undeserved.
After his bitter smile, the Nightmare Demon King grew excited again. They were now in the same boat. The stronger the Mechanical Demon King was, the greater their chances of winning.
Multiversal Entities were indeed powerful, but they could not enter after all. A Singularity Universe was enough to deal with them.

Next, you'll work with me and find opportunities to turn the other Demon Kings into undercover agents as well. With my strength, as long as I get the chance to quietly enter those Demon Kings' Hells, subduing them won't be difficult at all."
