Xie Jin, an archaeologist specializing in ancient biological civilizations, falls into an ice cave and dies while exploring an ice wall during a scientific expedition to Antarctica in the Dragon Kingdom. The dragon-ring jade pendant gifted to him by his maternal grandfather lights up.
When he wakes, he finds himself on Mars in the late Noahian period. The sun is scorching, the sky is fiery red, and the atmospheric pressure is only half of Earth's. Here exists a unique photosynthetic civilization of aerogel floating islands. Its people live among the clouds, with aerogel islands suspended 15 to 40 kilometers above the ground. Life takes the form of collective photosynthetic organisms made up of hexagonal algal cells with a group intelligence. They manage their energy through day-and-night modes and winter strategies, and their society is organized into mobile settlements.
After transmigrating, Xie Jin becomes a photosynthetic organism that harvests solar energy, and he also carries a technology exchange System. By accumulating photosynthetic energy and completing System tasks to exchange for resources, he gradually transforms Mars, develops interstellar technology, creates a cosmic travel system, and studies forms of life. In the end, he achieves immortality by becoming a crystal-matrix, interstellar nebula life form.
He later arrives on Earth, where he spends billions of years conducting biological experiments and modifications, laying the foundations for carbon-based life. He then begins exploring the stars and discovers that the Local Group lies within a cosmic void 2 billion light-years in diameter. He embarks on an endless exploration of it.
