According to what Neo Aldif himself and what he told Ashtel before the final battle between them, he had done thousands of experiments in search of a perfect plan.
Supporting Fade, spreading mimics everywhere, hiding the real body in secret hidden locations, collecting powerful summons, and forcefully merging them with other summons to create even more powerful hybrids.
Neo had tried almost all kinds of methods to improve himself and find a method to deal with Ashtel.
He even partnered with a dangerous demon just for the sake of gaining new forbidden knowledge that could be used against Ashtel.
Neo's plan was simple... if he can become strong enough to kill Ashtel Rex, he will become strong enough to threaten the world alliance, and nobody will dare to interfere in his future plans from there onwards.
