After three hundred years of hard training in Kunlun, the white-clothed immortal Dugu Yunchen and the black dragon Xiao Hei first entered the mortal world. They happened to meet Zhang Ling, a disciple of the miracle doctor, who was frightened by a giant python (the true form of the black dragon) and fell into the valley. They acted righteously and returned together on the dragon's wings. Little did they know that as time passed in the mountains, there were already many gangs and wars raging at the foot of the mountains. The Black Evil Cult coveted the secret medicine of the Divine Doctor's Medical Code, raided the mountain gate, slaughtered the creatures, and even used black magic to control the disciples, causing trouble in all directions.
In order to repay the life-saving grace and protect the peace of the world, Yun Chen used his golden elixir cultivation to frighten the Heisha cult, helped the Divine Doctor Sect to rescue the siege, and single-handedly rushed to Qingyang City to kill three elders in the transformation stage. Facing the leader of the Black Evil Sect who was in the tribulation period, he did not hesitate to activate the power of the dragon in the black jade with dragon patterns to end the evil spirit with the weak defeating the strong. In troubled times, the immortal chief in white who controls a dragon and the miracle doctor who cares about the common people support each other. On the way to quell the war and save the people, in the confrontation between swords, swords, shadows and immortal magic, they gradually form bonds that transcend immortality.
This is a legend about a cultivator breaking through the fog of mortal world and a miraculous doctor adhering to the original intention of medicine. It contains the heroism of flying a dragon in the sky, the tenderness of relying on each other in troubled times, and also the pursuit of questioning the common people and protecting justice.
