The low-level, medium-level and even high-level demons were preparing to attack human villages in search of monsters that fled hell, there was chaos in several villages And there were several cities that were destroyed, but they couldn't find

They went back to hell without success in their search, the demon king was destroying everything he looked at, he had lost something precious and would not give up so easily

The demon king called his generals to hold a meeting, the atmosphere was tense, everyone knew that the demon god was in full vain 

Demon King: I want you to find it, do whatever it takes, destroy cities, countries, anything that gets in your way, but I want you to bring back what belongs to me

Each general had his army and all hell was in chaos, as they received the news that the demon king would try to break the seal That kept him from getting out of hell

If he succeeded it would be a great victory for the demons, since the demon king was sealed they had lost their strength in the surface world, there were even demons who lived with humans, that made the demons angry more angry with the traitors who joined the

The demon king started tried several ways to destroy the Seal, but they were all flawed, but he never tried to use all of his magic, if he did that hell would collapse Because of his king's lack of mana, but since 1348 years since he was imprisoned, he used several demons to be his storage of living mana and living magic power, the Hell had gone through several problems because of these demons that would be used as a sacrifice, since the demon king would have to run out of mana, This often caused problems but as it was the demon king who ordered they couldn't say that they were having difficulty because of little mana, they could be killed if they complained 

Hell was going through a lot of problems, there were several demon deaths, but that didn't stop the demon king from continuing to stock up more and more mana and magic power

The demon king prepared all the demons that would be sacrificed, there were around 540 thousand demons. The demon king arrived at the door that he couldn't get through and there started to be several explosions, The mana and magic power was running out with just three waves of explosion he had made, but he had prepared for it, so he had dozens of demons as a sacrifice, Each demon had three explosions, the whole hell trembled with the shock wave and the mana explosion and the demon king stayed in this cycle for a long time
