The creatures in the Classic of Mountains and Seas are closely connected to reality, yet in four thousand years of scientific development, humanity had never discovered a single divine beast. Then, three thousand years into humanity's future, people accidentally discovered that the divine beasts recorded in the Classic of Mountains and Seas really existed. Later, a human genius invented the Heavenly Gate, which could merge the world of the Mountains and Seas with the real world. To test it, they captured large numbers of divine beasts and unfamiliar creatures. The weaker divine beasts were taken for experiments and died on operating tables, while the weaker humans died on the battlefield. Both sides suffered devastating losses.
This was opposed by the Divine Faith, whose members had transmigrated from the world of the Mountains and Seas and believed in the gods. But the technicians, obsessed with science, considered it perfectly normal. There was also the Shanhe faction, which sought peaceful coexistence, along with people and divine beasts holding other views. From then on, the continent was torn apart.
They split into numerous factions. The most powerful science-obsessed faction was led by a technology master of immense strength, who compiled a book called Subduing the Mountains and Seas, documenting every divine beast in the world. But after the sixth sect leader died, this legendary work fell into the hands of a generation committed to peaceful development. The Shanhe faction, which possessed the book, grew stronger and began protecting the divine beasts, believing in peace.
Hundreds of years later, the Shanhe faction's seventh young sect leader was born. But in the year he turned twenty, he fell in love with a divine beast. No one had fallen in love with a divine beast in over six thousand years. What shocked the technology masters was that the Shanhe faction actually accepted the seventh sect leader's love for one. War broke out once again, and the continent faced a new catastrophe...
