Using the lotus seed to control the Night Immortal King was something Wang Baole had done before. During the battle in the Mystic Luna Realm, Wang Baole had unintentionally used his lotus seed and directed the Night Immortal King into killing Chen Hui, a disciple from the Galactic Dusk Sect, with a single glance!
The Federation had their guesses regarding the matter. Some felt that it might have had something to do with Wang Baole. Regardless, there had been no evidence to prove anything. Most importantly, Wang Baole had not attracted as much attention then as he did now.
That had been the first time Wang Baole had successfully gained control over the Night Immortal King. The second time had been the earlier attempt. These two attempts had given him confidence. He was sure that the lotus seed wielded some form of control over the Night Immortal King.
