This is a novel about MMA, adapted from the real deeds of many characters. The full text shows the charm of fighting from different perspectives. Since the author has loved combat sports since he was a child, he has no choice but to lack talent and strength. I can only participate as a fan, even though I have some competition experience. But they are not A-level events, and the gold content is not high. However, it does not hinder the understanding and love of this sport. Because of personal experience, I can understand the hardship and helplessness of athletes. The main difference between this sport and other sports is that it goes against human nature. Many times, a boxer needs to meet the punch and fight back. Even if the punch hits the face. You also have to open your eyes to get beaten. Know how to get slapped in the face. Likewise, this sport is also the most cruel. Athletes struggle with injuries all the time. And the sports career is extremely short. An unexpected injury not only declares the game lost. It could very well spell the end of your career. Therefore, the author hopes to tell the stories of these athletes from a comprehensive perspective. Not gaining respect and sympathy for their sadness and pain. Just to let everyone know something about this seemingly simple sport. Likewise, they are athletes. Although there is a spine like steel. It has technology like a human weapon. However, they are also human beings, and they also have emotions and desires. They make the same mistakes we normal people do. Through an insight into their humanity. Allowing everyone to gain insight into their athletic careers. This is the author's original intention. I also hope to pass this novella. Let everyone know about MMA and like MMA.
