Ch. 341A lethal ambush
Andrew confronted the Blackheart Demon King, who pretended to surrender before helping Andrew lure the other Demon Kings into Blackheart Hell. Andrew and Blackheart destroyed their projections, and Andrew left Blackheart to serve as his battery for ten years before ruling Hell again.
- Andrew offered Blackheart the choice of death or five hundred years as a battery, but Lucifer and other Demon King Projections arrived to protect him.
- Lucifer and the projections prepared to fight Andrew, but Blackheart stabbed Lucifer with his Flame Greatsword and revealed he had been loyal to Andrew all along.
- Andrew summoned the Destroyer Mech and attacked Nightmare while he and Blackheart used Blackheart Hell's power to fight the projections.
- Andrew and Blackheart defeated every Demon King Projection with the help of demons and Andrew's nuclear bombs.
- Andrew told Blackheart to spend ten years as a battery, after which he would release him to rule Blackheart Hell again.
