The End of National Martial Arts

Not cultivating immortality, not fantasy. There are only real martial arts with bright power that breaks through the air, dark power that hurts people, and invisible power, and the modern world of flesh and blood against gun technology. This is the last era of national martial arts and the last battlefield of heroes. The black box has arrived, and the end is coming - are you ready to step into this real arena where superiority and inferiority are determined, and life and death are decided?
