In 2333, the virtual world was completely improved, and this world also promulgated the "2333 Law" as the first law of the virtual world. At the same time, the rapid development of technology has allowed robots to enter the human society and replaced most people's work. In order to protect the stability of society, the currency of the virtual world and the currency of the real world have begun to officially circulate for the first time. This is to allow people who have lost their jobs and are over-energy to find a place to spend energy so that they will not cause trouble all day long.
