As an outcast from a poor family, Lin Feng only wanted to help the world and make a living. Until he met the dying Jin Yiwei in a ruined temple on a rainy night, and the other party entrusted him with a jade engraved with dragon patterns before his death. "The dragon's veins will wither... The world... Is in chaos...". The next day, the mysterious woman Liu Ruyan broke into the hospital with a knife: "Hand over the jade, or die!" Lin Feng was forced into the whirlpool, and then he discovered that the faint king used evil magic to suck the dragon's blood essence in order to seek immortality. When he tried to use medical skills to repair the scars on the earth's veins, the entire capital suddenly shook. The wail of the dragon's veins was actually more deafening than the mourning of all the people.
