I Have Become a Taoist, but I Was Thrown Back to Modern Times by the System

After practicing for thousands of years, Lin Xuan finally stepped into the ultimate realm of Tao and became the only Taoist master in the three realms. He was supposed to transcend heaven and earth and leave this world, but at the moment of enlightenment, he was forcibly bound by a mysterious "system" and was thrown directly back to the modern earth where spiritual energy was exhausted. What's even more ridiculous is—— The system only gives him one task: Within three months, the era of universal cultivation of immortality will begin. Otherwise, erase. How to practice in a world that has lost its aura? How can a mortal body defy heaven? But for Lin Xuan—— Since there is no road, then make a road with your own hands. Release spiritual energy, reshape the rules of heaven and earth, and guide all living beings into the path of spiritual practice. However, he soon discovered—— He is not the only one who has returned to modern times. Former Taoist companion Ji Hanyue, best friend Qin Wuye, old enemy Luo Cang... Those beings who once stood at the pinnacle of the Three Realms are coming to the world in different identities. Some people are hiding in the dark, and some are ready to make a move. When practice returns, order collapses and the world loses control. And the starting point of it all—— It was Lin Xuan. This time, he is not just Tao Zun. Even more—— The usher in a new era.
