Lu Chen fell from the fairy world and returned to his hometown, Earth, as a remnant of his soul. He became a business tycoon that he had only seen in the news in his previous life. He discovered that this seemingly ordinary technological era actually lurked a "high-dimensional doomsday" that could annihilate the entire universe. The way of heaven is unkind and regards all things as stupid dogs. This time, he decided to be the more "merciful" sword holder.
As the president of a technology group, he is making great changes and guiding the progress of human civilization; while he is quietly releasing the sealed aura, allowing long-extinct demons and ancient cultivators to reappear in the world. When the familiar catastrophe of cultivating immortals and the unfamiliar crisis in the starry sky came at the same time, and the whole world was the enemy, he stood on the top of the ruins of civilization, facing the starry sky and whispered: "I sound the death knell of doomsday for mankind, and also open the door to a new era for them."
