This book is about an ordinary person who just wants to live a stable life. After being knocked to the ground from his daily life by an out-of-bounds hand, he did not choose to stand there and curse, but got up and returned the energy to the person who deserved it. This is not a story about "a courier boy becomes a superhero", but a story about "ordinary people are forced to be the center of the storm and discover that they are more capable than they thought". The theme falls on a passive initiative - the protagonist Chen Mo never thought about saving the world from beginning to end. He just wanted to live, he just wanted not to hurt the people around him, and he just wanted to figure out why it was him. But this "not wanting" pushed him to take a path that no one dared to take.
