Immortal King Wuzhong died a miserable death, and then Wushi appeared in the Later Era. He defied the heavens all the way, and in the end, he had undoubtedly become an Immortal Emperor.
He had achieved something Wuzhong would never have dared imagine.
Back then, Immortal King Wuzhong had already sensed that his Dao was incomplete, that there was something beyond his Dao of Wuzhong. But dying and starting over carried too great a risk. Unless forced into a corner, who would willingly place their hopes in what came after death?
Meng Chuan reckoned that back then, even if Wuzhong had completed his Great Dao, he would have been content to reach Butcher's level...
As for breaking through from Immortal King to Immortal Emperor, in that era, it had been more of a beautiful dream.
Yet the result was an Immortal Emperor Wushi.
Then there was the Azure Emperor. His case was not quite as fantastical as Wushi's; at least he had a foundation. Though he had fallen short later in the original story—yes, even though the Azure Emperor would reach the peak of the Human Dao Realm, compared to what the Green Lotus Immortal King had achieved, he had indeed fallen short.
As for the Immortal Monk King, that was due to the peculiar nature of Buddhism.
He truly had died, but Amitabha Great Emperor bore traces of him, as though he had been reborn. It was nothing like possession.
If Amitabha Great Emperor became an Immortal King in the future, then with the right opportunity, he might recall some things from his days as the Immortal Monk King. But he would still be Amitabha Great Emperor.
The same went for Wushi and the Azure Emperor. If Wushi became an Immortal King, a Quasi-Immortal Emperor, or an Immortal Emperor
