Li Yi abolished the Sacrifice Spell, granting freedom to each cultivation expert, fulfilling his earlier promise, and because he had now entered the One Flower Realm, his combat power was comparable to that of a Demon King, he had the absolute confidence to subdue everyone.
Using the Sacrifice Spell to constrain these cultivation experts was a helpless move due to his weaker strength at the time. After all, back then Li Yi didn't want to lead a group of cultivation experts across worlds only to encounter betrayal and scheming.
Fortunately, these cultivation experts were also sensible people and understood Li Yi's concerns, which is why they suggested the Sacrifice Spell. Compared to staying in the End of Dharma World, they would rather perform the Sacrifice Spell in exchange for a chance to cross worlds.
There was no issue of taking advantage or being at a loss, it was merely mutual necessity, mutual assistance, and mutual benefit.
