Noah was left with only thirty-six slaves before he decided to take a different approach but only twenty of them could be matched with the magical beasts chained in the underground structure.
That number further diminished as Noah continued with his experiments.
It took a few attempts before he could tune his instincts, more slaves died when the fusion reached the internal organs, but, ultimately, he managed to achieve some small success.
Noah's concentration was at its peak as he controlled the fusion between an elderly man and a Fog hawk, refined liquid "Breath" of the wind element continued to be depleted as the organs of the slaves were modified.
That was the twelfth time that he had reached that point, three slaves had died before his instincts became able to match the perfect magical beast for each cultivator but he had finally reached the final part of the fusion.
