A primeval shell

All along, there had been a rule in the nine great sects. That was, the most outstanding heaven's favorites of the current generation had to go to a "strange" place to find "magic" before they formed their Aurous core ...

A long time ago, the nine great sects had all followed this rule extremely strictly.

But later on ... The 'techniques' found in the 'strange' land did not have any subsequent inheritances, so the path of Dao became more and more difficult.

In the end, they would either stop at a certain stage before transcending the Tribulation or give up on the "technique" that they had risked their lives to obtain ... In comparison, with the "technique" provided by the sect and with a complete Daoist line and inheritance, as long as they had the aptitude, they could basically reach the Return To Void stage, the Dao integration stage ... And even transcend the Tribulation!

Thus, this rule gradually became a formality.
