Without going out at all, Jayden stayed in the cave and absorbed the Cores of the 2nd Zone demons, meanwhile, the Rakshasa were on a hunt killing lots of demons. Jayden took separate time daily to train, going to the Hell world and going through extreme level battles.
After each time coming back from there he would be very exhausted both mentally and physically, under the pressure of the killing intent that was concentrated on him by so many creatures, he was also able to train his mind.
The formation of his new core was taking even longer than the previous one and he could tell that the energy that would be stored in this core would be higher than the 1st core.
Eve constantly ate the core of all the 1st Zone demons and some of the 2nd Zone demons, while her aura also became stronger.
