This book is also called "Eternal Night Fugue"
In the century of cataclysm, Central Continent was left behind, isolated from the rest of the world, ferocious with war, and alien beasts rampant. Human beings huddled in the cracks. In the first fifty years, the superpowers struggled to survive the crisis. In the next hundred years, martial arts were first established. They tempered the essence and blood of alien beasts and channeled the orifices all over the body, finally forming a system. In the last fifty years, all the people have practiced martial arts, their blood has set fire to the prairie fire, and the torch of civilization has been rekindled!
