1. The far-field GC-9179 Tower Nebula is a niche exploration star field that is outside the mainstream interstellar routes. The Joint Interstellar Scientific Research Agency dispatched a surveyor civilian detection return capsule to go deep into the hinterland of the nebula to collect nebula free particles, space thin-layer fluctuation data, and extraterrestrial gaseous material samples. After completing the half-year deep space exploration mission, it returned to Earth according to the established route.
2. When the return capsule entered the critical layer of the near-Earth atmosphere, the original free energy of the nebula stored in the capsule accidentally leaked out. It happened to form a rare two-way resonance with the thermonuclear energy of the mantle that had been dormant for tens of millions of years in the Kashidjibu extinct volcano in the Dagmu Basin of the Earth. The two special energies instantly tore apart the thin cracks in ancient natural space hidden in the shallow layers of the earth's surface.
3. The return capsule lost its route traction, deviated from the preset landing coordinates, and fell straight into the mezzanine of the volcanic hinterland. All external directional communication frequency bands in the cabin were completely blocked by the turbulent energy of the mezzanine. The ground monitoring station only captured the last weak positioning light spot, and then lost all contact. There was no distress signal and no trace of the wreckage.
4. The Interstellar Science and Technology Bureau urgently formed a civilian joint search and rescue team. The team was led by sisters Yingxuan and Yingyi, who have experience in interstellar navigation across the world. They teamed up with stratigraphic research interns, two-way energy researchers, and field landing security specialists to go to the basin volcanic zone for on-site exploration. Check the entrance to the space gap, go deep into the secret realm of the mezzanine, search for the lost detection return capsule, and retrieve precious nebula detection data. At the same time, measure the expansion speed of the space gap, stabilize the thin natural space gap on the verge of collapse, and prevent the turbulent energy of the mezzanine alien world from reversely flowing into the earth.
