After the beginning of the new century, an unprecedented global network was established to make every kind of task easier for its users. Anyone with an identity chip implanted in their body could log in at any time and enjoy a convenient life. In 2079 of the New Earth Calendar, the electronic virus Punishing, named after the word "punishment," erupted without warning. Every human and intelligent machine connected to the network was infected. The virus rapidly destroyed fragile human bodies, while infected machines fell under its control and became frenzied killing machines. Even the life-regulation systems that maintained Earth's ecological balance stopped working properly after being infected. After less than a century of resistance, the once highly prosperous human civilization had nearly vanished from Earth. The survivors fled into deep space, leaving behind countless infected machines wandering the land.
