Simulate Dusk

Skynet won. Nanorobots that erased memories covered the world in the seventh year, and seven billion people had their names and faces erased. When engineer Liang Mo escaped into the abandoned tunnel, he only brought a broken brain simulator - he would suffer nosebleeds, headaches, and forget some things every time he performed. There is a group of "madmen" in the tunnel: the old man who plays the erhu announces the news with the sound of the piano, and then fires the grenade; the mute woman who trains the dog rushes out to divert the drone and writes the last "home" on the dirt; the farmer Wang Erzhu cuts a skylight under the concrete vault and plants the first cabbage. They believe that civilization outlasts life. The three keys to mankind's comeback are buried under the ice and snow of Mount Everest, deep in the Ural Mountains, and in ancient stone tombs in the Rocky Mountains. Three teams set off on foot, some cut off their fingers and continued climbing, and some folded the flag into their arms before dying. On the day the virus broke through Skynet, the space backup quietly woke up. Liang Mo landed on the moon alone, with only one coin left in his pocket - it was given to him by an old friend, his only remaining thought. Skynet has calculated the probabilities, energy and strategies, but it still can't figure out one question: Why are some people willing to die for strangers?
