Beginning with the Cyanobacterial Civilization of the Precambrian

In the Precambrian period, on the eve of the Great Oxidation Event, a group of cyanobacteria gave birth to a will of its own. From volcanic hydrothermal fluids igniting the fire of civilization, to symbiotic collapse and the road to escape, Passing through the highly toxic sulfide restricted area, singing a tragic song of civilization. From the restart of civilization in the near-light zone of shallow seas to the establishment of magnificent empires all over the world, The highly toxic oxygen became the cornerstone of civilization. In the lonely primitive ocean, the cyanobacteria empire was crowned among the ruins. The death cycle of oxygen production is the end of civilization. Under the endless glaciers is the last afterglow of civilization. When the era restarts, can the new overlord take over the twilight of the Cyanobacteria Empire and embark on a journey to chase the light again?
