Luo Han and Yuan Han either failed or were mediocre in modern society. After their accidental death, their souls traveled to a fantasy world of swords and magic. This world is distorted by darkness. In order to protect their own interests, the theocratic church and the aristocracy try their best to prevent the protagonist from changing the world. Although the protagonists possess modern knowledge, they are limited in combat due to their shortcomings in abilities, and are misunderstood by the indigenous people as the source of darkness. At the same time, dark forces continue to erode and the world faces a racial crisis. The protagonists are running out of time to save the world. In the harsh environment of survival crisis, they relied on their pragmatism and adaptability to use modern knowledge to solve various problems, such as inventing tools to improve people's livelihood, using modern tactics to win wars, and gradually building up power in an attempt to break the old order and save the world on the verge of collapse.
