'For now, let's listen to him, and if he really has a shortcut to breakthrough to the Soul Transformation, I don't mind using it.'
While giving permission to Ethan to explain his plan, the Ancient Evil Spirit silently thought in its head.
Of course, for now, it was just listening and wouldn't take such methods.
'Moreover, I don't mind giving it a try as long as his methods are useful. But that doesn't mean I will take him as my slave.'
From the beginning, the Ancient Evil Spirit had no plans to let Ethan leave, even if Ethan was willing to become a slave for it.
According to the Ancestral Knowledge, it awakened during its second awakening, and there were a few Ancient Evil Spirits that were tempted by the Heavenly Sons and the Abyssal Sons with similar contracts.
In the end, within a few years, they easily broke through their Slave Marks and devoured the Ancient Evil Spirits to become even more powerful.
