Avengers: the Last Arrow

Eleven years after Thanos snapped his fingers, half of all life has not returned. Earth's civilization has degenerated into ruins of city-states. The Avengers have long existed in name only. The remaining heroes are scattered everywhere. Some have become warlords, some have become legends, and some have become the things they once swore to destroy. Former S. H. I. E. L. D. Agent Clint Barton is the last former Avenger still on duty. For eleven years, he has only done one thing - to find his daughter Laila, who disappeared in the snap. From New York to Tokyo, from Tokyo to Moscow, he followed every clue and traveled through the dead wasteland known as the "Plain of Bones" until he discovered a transparent city that should not exist. There is a wall in the city that is engraved with the laws of the universe, recording a rule that has been deliberately forgotten by all civilizations: when the total amount of life in a universe falls below a critical value, the harvesting process starts. Snapping your fingers is not a disaster, just a trigger. The real end is when the universe itself decides to abandon the earth. The only exception clause reads: If there is an individual who can prove that the universe is still worthy of survival, the harvest will be suspended. And Clint discovered that his daughter Lila was exactly that "exception". When the universe decides that you don't deserve to exist, what do you say to counter it? Not power, not gems, not the identity of a hero - but the obsession of a father who has never stopped for eleven years, and the last arrow in his quiver.
