Hundreds of years ago, a sudden meteorite impact collapsed the entire world into two symbiotic and absolutely isolated continents. In order to save human civilisation, hundreds of scientists from the original continent, led by Rosenberg, developed a new type of energy supply device (card) with the help of all the countries. The protagonist, Chen Mu, from a weak, helpless, poor and unsupported teenager, after a series of adventures full of struggles and trials, did not give up and retreat, but still relied on his kind and tolerant nature, his own outstanding efforts and the enthusiasm of friends and family around him to help, and ultimately broke through the obstacles, growing into a righteous, moral and capable of the positive leadership of the story.
