"In 2045 AD, the tenth year after the meteorite fell, a report from Kyoto: Scientific researchers explained that as the vitality of Blue Star continued to rise, some geniuses among people began to show their talents. The so-called vitality is just a name given by scientific researchers. What it is has not been studied, but most groups can feel it, and a small number of geniuses can absorb it into the body to enhance their physical fitness."
"In 2066 AD, a peerless genius appeared. Li Yang of China compiled a practice method called "Building Body Art", which allowed most people to practice and enhance their physical fitness.
At this point, mankind has announced that it has entered a new era - the first year of the Martial Era."
