The alarm tore through the dawn, and a strange liquid sapphire "seventh hand" appeared on the engineer's quantum watch. Its fluctuations were synchronized with his daughter Ella's topological building block toy. At the same time, his wife Qi Ya drilled a black plane at 2,987 meters underground on Mars, engraved with the same seven-fold ring symbol, and a nebula embryo pulsing in the center, which was a "sentinel" warning of the extinction of Martian civilization three million years ago. The vacuum decay ripple erupting in the center of the Milky Way is swallowing up space and time and will destroy the solar system in 13 months. The bell turned into a shield and crystallized in the torrent of antimatter; Ella's pure consciousness merged into the core of the giant tower. The City of Light tragically reorganized into a giant tower across the sea of stars. Ella turned into a star cocoon, integrating her father's will, AI logic and Mars fire, transforming the destructive energy into billions of "light seeds" and shooting them into the deep space, lighting up the galactic lighthouse. The tombstone is also a cradle, the cocoon of stars awakens in the sea of quantum flowers, and the stars flow through the fingertips, pointing to the heartbeat of the new universe revealed in the cracks.
