Cain wanted nothing more than to use the Wave Virus immediately. Still, he was exhausted and understood that the generation of a new bloodline would put his body under immense stress.
The Grand Wave Virus would do all the work on its own, but it would demand a massive amount of vitality and energy, so it was better if he was in peak physical and mental condition for the job.
Haste makes waste, and he had put too much and spent too much money into the Grand Wave Virus for a mistake to happen now. Cain spent another 100 points of Destiny Force for the [Earth Fiend Flame] to fill his body with energy and vitality before sleeping.
Cain allowed his body to wake up independently after it had enough rest. He then sent twenty-five corpses of Wave Champion Beast into the [Devourer Dimension] before making a pile of hearts appear before him.
