Shen Han, 27 years old, is a top international artificial intelligence engineer with a cold personality and poor social skills. Forced by her family to get married, she casually got married to a mysterious beauty who called herself an "amnesiac wandering girl." The day after the wedding, my wife disappeared, leaving a message saying that she was going to "put down the rebellion." Shen Han thought he was being fooled, so he turned around and continued his scientific research. Three months later, the global celestial phenomena changed, and an alien fleet descended on the earth. They called themselves the vanguard of the "Shadow Empire" and demanded the handover of their "Exiled Queen." Shen Han looked at the familiar figure sitting on an alien throne and wearing a crown in the holographic projection, and was completely confused - that was his flash marriage wife! What's even more terrifying is that the ransom offered by the Shadow Empire is: either hand over the person or use the entire earth to offset the debt. The world is in panic, and politicians in various countries are helpless. Only Shen Han, relying on his "superconducting brain" (gold finger: which can instantly analyze any energy and information structure and deduce the cracking path) to understand the laws of the universe, started a series of unbelievable operations: assassinating alien assassins with earthly hotpot ingredients, inserting the five-star red flag into the main gun barrel of an alien battleship, and asking for "betrothal gifts" without changing his expression in front of a global live broadcast. Iceberg hard-core scientists VS ferocious alien marriage gangs, an absurd and hard-core interstellar defense battle begins.
