In ancient times, there were two civilization systems in the universe - the civilization of immortality and the civilization of science and technology. The civilization of cultivating immortals is based on spiritual energy. Cultivators swallow the essence of heaven and earth to temper their physical bodies and souls, and eventually they can shatter the void and transcend the universe. Scientific and technological civilization is based on the laws of matter, from particles to stars, from genes to dimensions, and conquers all unknowns with rationality and calculation.
The two major civilizations once had a "War of Annihilation" across the star field in ancient times, which ended in the simultaneous decline of both sides. The spiritual veins of the civilization of cultivating immortals have dried up, and the monks have withered; the interstellar network of scientific and technological civilization has collapsed, and civilization has retreated. The "Path Source Star", which once connected the two major systems, was also sealed in that war and sank into the depths of the void.
Tens of millions of years later, on a blue planet called Earth at the edge of the Milky Way, the power of two civilizations sprouted again in a secret way.
