In the third year of Yongle, Shen Yuan, captain of the Ming Dynasty's pioneer fleet, was ordered to explore the Western route, but he entered a bloody battle that lasted for three thousand years in the two river basins - the fateful battle between the blood descendants and the moon wolves, two ancient races. Seventy blood descendants versus thirty thousand werewolves, Shen Yuan could have sailed away, but instead crossed the line and made a bet to the Moon Wolf King himself. Cut off the Wolf King's right arm with one knife, giving him a month's rest.
But the war was far from over. A blood contract was concluded, the prince was martyred, and the princess fell into a deep sleep after saving her with blood. Shen Yuan returned home and reported truthfully. Chengzu's orders were briefly recorded in "Yongle Dadian" and he was allowed to resign. In the next twenty years, he made seven voyages to the West, guarding the sarcophagus alone every year until he died of illness at sea.
Six hundred years later, Shen Su, a descendant of the Shen family, discovered fragments of records in the ruins. The birthmark on the back of his hand glowed hotly, guiding him into the depths of the stone chamber - the sarcophagus shattered and a pair of purple-red eyes slowly opened.
The blood descendants are not dead, and neither are the werewolves.
Purpose: Cut off the divine arm with a mortal body, keep the promise of six hundred years of blood, and have bones in the world.
