For a long time, Shen Yuan did not consider using Heaven's Decree Secret Order again, because he was well aware that it was an opportunity, yet also hid great risks.
In today's Primal Chaos Realm, aside from those old monsters in the grotto heavens sacred grounds, very few could threaten Shen Yuan, and he could almost do as he pleased without restraint.
However, if he were to return to the cultivation golden age of ten thousand years ago, with the Immortal Path of the Primal Chaos Realm flourishing and powerful experts emerging in large numbers from every great grotto heavens blessed land—even the Tao Harmony Taoist Doyens and long-lived immortal beings could walk the world freely.
In such a golden age, should an accident occur, Shen Yuan might not even have the strength to ensure his own safety.
