With the Dao Flower's help, Ao Lei would not have to go through the difficult process of Dao completion when he broke through to the sealed immortal realm.
All he needed to do was accumulate his cultivation foundation until it reached that level.
Actually, Ye Xuan had just thought of this method, and was just testing it out. He had not expected it to actually succeed, and was beside himself with excitement.
The method Ye Xuan used on Ao Lei was actually not much different from the method he chose when he stepped into the sealed immortal realm, just that he was using his own foundation to establish Ao Lei's.
That being said, although Ao Lei would not have to complete his Dao, if he went in the wrong cultivation direction in the future, he might face a huge crisis if he was not careful.
