When Daoist Xiantian started over after disbanding his cultivation and fled to the outside world, coming into contact with the concept of the "Five Great Immortal Sects" for the first time—and learning that one of them was the sect he had founded—he was stunned for quite a while and even doubted for a moment that it was merely a coincidence of names.
Only after confirming the address did he truly believe it was not just a coincidence but indeed the very sect he had founded.
The word outside was that the Five Great Immortal Sects either had cultivators at the Transcendance Tribulation Stage, or they possessed means on par with those of the Transcendance Tribulation Stage. Such statements had already surprised him greatly.
After all, that was the exalted Transcendance Tribulation Stage.
Now, arriving at Captive Peak and seeing all these legendary characters being held captive—Transcendance Tribulation Stage cultivators were one thing, but there were even two semi-immortals!
