Melkor struggled to make a single choice out of three promising and powerful qi cultivation methods.
Each of them would have massive implications for his career as well as the Larkinson Clan if he could make a huge difference in a battle.
The homebrew Design Spirit Contract Qi Cultivation Method pretty much guaranteed that Melkor would become powerful enough in his own way. He could channel the power of a contracted design spirit for a longer period of time and gradually become able to perform similar abilities by relying on his own strength.
The Combat Spell Array Master Qi Cultivation Method would cause him to miss out on gaining more direct combat power, but he would gain the capability to affect the battlefield on a large scale, thereby allowing him to boost friendly units and debilitate enemy units en masse.
