I Stockpiled Trillions of Heavenly Treasures, Waiting for Spiritual Qi Revival

After the spiritual qi revival, all of humanity regretted it too late! The cucumbers and cabbages that used to be everywhere absorbed spiritual energy and became priceless, supreme spirit herbs, never to grow again! But at the time, people didn't realize how valuable they were, and they all rotted in the fields! A tattered book propping up a table leg in a ruined temple turned out to be a Ninth-Rank cultivation manual. A junk collector took it away and became the strongest Immortal Venerable! A worthless mine had just changed hands when it sprouted an enormous quantity of spirit stones, turning the lucky buyer into the richest person in the cultivation world! Yun An is reborn and returns to the time before the spiritual qi revival. His ambition isn't great. “I just want to spend trillions, monopolize all the materials before the natural treasures awaken, then hole up on my little mountain and wait for their value to rise.” That's not all. Yun An lays down formations in advance to block the entrance, turning an ancient secret realm coveted by everyone into a private dungeon he can clear alone. He even raises great demons ahead of time, turning those overlord slayers into adorable little watchdogs at home. While people outside are bashing each other over a single stalk of spirit chives, Yun An is already sitting in a blessed grotto, munching on all kinds of discontinued immortal pills as snacks, burning top-tier cultivation manuals for firewood, and skimming spirit stones across the water for fun. He lives a life where even sleeping lets him cultivate faster than everyone else.
