The Foundation Has Been Established but the Spiritual Energy Has Not yet Recovered?

"Why do other people's time travels involve modern times and ancient times, while I travel from ancient times to modern times?" After the foundation-building monk moved away and tried to use what he had learned throughout his life and combined it with all the stories told by the old village chief, he still could not explain the brightly lit modern city in front of him. In desperation, Qianyuan had to change into the memory thinking brought by the "original owner" after time travel. "This world used to be rich in spiritual energy, but it did not begin to decline until the 1930s. As a result, ordinary people had no access to the Immortal Path, or even knew of its existence." The depletion of spiritual energy would be a disgrace to any monk, but it was no hindrance to moving away. He even vaguely felt that practicing in modern times seemed to be more comfortable than practicing in the ancient wilderness where spiritual energy was abundant! "The spiritual energy is exhausted? Alas, modern people are afraid of hardship. Who said this spiritual energy is exhausted? This spiritual energy is too abundant!" "People are not good enough. Don't blame the uneven road. There are indeed golden fingers for time travel." "Bah! What a golden finger, this is my innate talent and instinct!" Suddenly, Qianyuan thought of something: "Wait a minute, the spiritual energy in the ancient wilderness was abundant, which led to the rampage of spiritual beasts, while the modern spiritual energy declined, making it difficult to practice." "Since I can travel back and forth between the two worlds, wouldn't it be wonderful if I could take apart the east and make up for the west, and pour the aura of the ancient wilderness into the present world? It would be a huge business opportunity! No, it's a fairy fate!" (Also known as: I've already built the foundation, why hasn't my spiritual energy recovered yet?)
