At 14:33 on August 12, 2026, during the global total solar eclipse, there should have been an ordinary celestial phenomenon with only the moon blocking the sun, but a beam of unknown cosmic gravitational waves broke into the solar system, causing global gravity anomalies. These "offline" 7.3 Seconds tore apart the barrier between reality and unknown dimensions - the Eastern Dragon appeared, the ancient demon resurrected, and the global magnetic field changed dramatically.
Meanwhile, human genetic locks are loosening in the radiation. Some people awakened supernatural powers, some were transformed into monsters, and the world order collapsed overnight. In this catastrophe, retired special forces Long Zhan and doctor of paleontology Su Xi respectively awakened the "Ancestral Dragon Holy Body" and "All-Seeing Spiritual Eyes" that were rare in ten thousand years. From meeting strangers to fighting side by side, from being wary of each other to promising life and death, they fight their way through the mountains of corpses and seas of blood, and finally reveal the truth behind the disaster: all this is not a natural disaster, but the ultimate showdown between ancient gods and demons and the fate of the human race after the seal is loosened.
