After Becoming the Richest Man, I Used Black Technology to Unify the World

[Urban + cool writing + invincible + black technology + multiple heroines + behind-the-scenes boss] Ten years after traveling through the parallel world, Zhao Changan became the richest man in the world, and then activated a mission system! This system has only one mission: to unify the world! The mission reward is: the host can realize a wish! According to the system regulations, as long as a country is established, system points can be continuously obtained through the number of population and territory! System points can be exchanged for various special items in the system mall! For example: hypersonic nuclear missiles! The sixth generation smart fighter! Liquid Metal Terminator! Controllable nuclear fusion technology! Super artificial intelligence! Etc! There is even immortality technology! Zhao Changan, who originally wanted to retire early, is now more motivated! "Buy territory at a high price, the bigger the better!" "Accept refugees in the long term, the more the better!" "Do you want to sell your country's territory?" "Not selling?" Sorry, I can only grab it!
