A Science Student Mistakenly Enters the World of Cultivating Immortals

Qin Heng, a genius in science, brought the technology tree of the 21st century to a world of cultivating immortals where the weak and the strong prey on each other. Here, humans, beasts, and demons are divided among themselves, and survival is the only rule. He thought he was reborn as a good child. He was the beloved only son of a wealthy family in the capital, with loving parents and two stunning sisters who regarded him as a treasure. He thought that he could use mathematics, physics and chemistry to open up an easy road to becoming an immortal, and he would be able to live happily in the world. Until that day... The inhuman blood in his body suddenly awakened, and all the veils of tenderness were completely torn apart. The human race regards him as an alien and vows to punish him immediately; the demon race covets his "great help"; and the survival of the beast race depends on him alone. His father, who loved him so much in the past, had a careful calculation behind his smile? What kind of unbearable relationship does the sect goddess, who desperately protected him from escaping, have with him? And how should he face the heavy affection between the two sisters he swore to protect? In this catastrophe that swept through the three races, the only thing he could rely on was the "Survival Algorithm" in his mind. Calculate interests, calculate gains and losses, but... You can't calculate people's hearts. Is he a human, a beast, or a god who is above the rules?
