Continuing to keep an eye on the battle and watching out for any changes that took place as the winged lion demon beast and the demonic cultivator both continued to rapidly grow stronger with each passing second, Xuan Hao ultimately decided to wait until the demonic cultivator broke through to the Demon Lord Realm before he would do anything.
The main reason for that being that he could use the opportunity while the demonic cultivator in the Demon King Realm behind the scenes was unaware of his presence to help the winged lion demon beast rapidly increase its strength and reach the Sixth Tribulation of the Soul Ascension Realm in a period of time that would normally be impossible without the great sacrifice from the side of the hidden Demon King Realm demonic cultivator.
