Non-Zero Game

Link, who had just graduated from high school, woke up 50 years later due to an accident. In 50 years, the world has undergone earth-shaking changes. Link learned from his niece that his brother Lin Mo had participated in a game project called Non-Zero Game during the past 50 years... My name is Link. I'm not a brave man. I don't have a sword. I don't know if I can save the world. But I want to protect everything my brother left for me.
