Void Puzzle

[No routines, no cool writing, no harem, but attitude] The story that takes place after "Crossing the Wei Mang". As the earth enters an irreversible warming path and becomes uninhabitable for humans, humans launch the "Dandelion Project", which digitizes the entire human civilization. After compression, encoding and modulation, it turns into radio signals and broadcasts into the depths of the universe, hoping to encounter civilizations with a certain level of technology. The invention demodulates, decodes and decompresses the received signal, then carries the information in a new carrier to continue human civilization - even part of it... I don't know how long later, there is a incomplete civilization and a group of incomplete people on the edge of the universe, but they want to be complete. The young man can save a decadent man who committed suicide by jumping into a river because he was laid off and unemployed; he can stop a loveless woman from hanging herself; he can persuade an old man who has been abandoned by his children and is about to jump off a building not to take the last step; he can even help a child who is lost in a chaotic street find his parents, but he knows nothing about his own life experience. He wants to search, and they all want to search, in the vast void of the universe, where have the past civilizations and the loved ones gone? How to find it? What kind of danger will he experience? What kind of vortex are you involved in?
