A Soul Contract bound the soul. Unless he dissolved it himself, the other party could not undo it, no matter how extraordinary their abilities were.
Take the Undying Emperor, Little Yellow Chicken, for example. Even when Zhang Xuan had been only a God King and Little Yellow Chicken an Emperor, the latter had still been unable to break their agreement.
To prevent this fellow from turning against him and causing a backlash, he had specifically established the contract back on the Master Continent. Even if the other party escaped the Book of Heaven's Path, they would still be unable to escape the agreement between their souls!
"A Soul Contract indeed cannot be separated from the sea of consciousness, but I absorbed a special gas that can dissolve even the Heavenly Dao. Dissolving a contract like this isn't difficult... With enough power directed at the place where the contract resides, it can be done!"
Ruthless Person said.
A Soul Contract was established on the foundation of the Heavenly Dao. If that special power could dissolve even the God Realm's Heavenly Dao, how difficult could dissolving a Soul Contract be, provided it was handled properly?
"So that's how it works..." Zhang Xuan's eyes flashed.
"Consider all these explanations my thanks for bringing me to the God Realm!"
Having finished his explanation, Ruthless Person said no more. His aura grew increasingly ancient and remote, and the black hole behind him expanded further. Clearly, he had devoured an unknown amount of power to nourish himself while they spoke.
"Zhang Xuan, the more that black hole devours, the stronger he becomes..."
Luo Ruoxi also noticed something was wrong and hurriedly sent him a telepathic message.
"Get ready to attack!" With his doubts cleared away, Zhang Xuan took a deep breath and abruptly raised his sword.
