After experiencing several mainline tasks, Shen Yuan had roughly figured out the various key factors that influenced the mainline tasks.
Due to the time span of tens of thousands of years, many of the conditions needed to complete the mainline tasks were difficult to meet, and he could only resort to using other things to substitute to a certain extent.
In this process, if Shen Yuan obtained better things to replace the original necessary conditions, it would upgrade the mainline task, thus affecting the final reward calculation of the mainline task.
For example, he had replaced a Sect spirit pool with a Natural Spirit Pool, and the sect competition involving only Falling Clouds Sect had turned into a competition involving several grotto heavens sacred grounds.
Many of these changes were not deliberate actions by Shen Yuan, but rather, he had no choice but to proceed in such a manner because the original conditions were unattainable.
