Cosmic Professional Gladiator

In 2036, mankind steps foot on Mars for the first time.
In 2052, Earth holds the first World Martial Arts Tournament, a global martial arts competition watched by the entire planet.
Top professional gladiator, “Spear Demon” Xu Jingming, retires at the prime age of 26 with a body ridden with injuries.
One day, the United Nations announces that mankind would be ushering in a new era for human evolution. Advanced technology had been found on Mars, a secret kept to this day. Research had been carried out to use science to augment human evolution.
All of mankind can now evolve themselves by partaking in this VR experience using the freely distributed VR headset.
