Mo Gan is the fourth son of Shenlong and is in charge of winter. He was bleeding with black blood and refused to open his deep eyes easily. From that day when he was beaten into Yechuan by the dragon, he and his tribe never smiled again. The bloodline of Shenlong will not be invalidated just because of the end of life, and Mogan has been passed down among the Yechuan tribe from generation to generation. At that moment, Mo Gan died, and the dragon's veins condensed on the body of a full-month baby. Everyone will assert that death is the greatest honor to this child. Fortunately, his identity as the son of the leader was destined to be thrown into Kunlun on this day. In the falling black shadow, the dragon who had been sleeping for thousands of years slightly raised his right eye and immediately fell into a deep sleep. But his right eye was clear enough to save the child and raise him until he was sixteen or seventeen - after all, he couldn't remember the time in the world. This child became the happiest part of Mo Gan's long, hate-filled life. It can be said that it was like this before leaving the Moon River Valley. Since being cursed and unable to leave Yechuan for more than seven days, each generation of Mo Gan will gradually find the memories of their previous lives, about revenge, and about curses. The safety of the entire clan is theirs and his lifelong responsibility. However, his memory was so gloomy because the footprints he could measure were too close. They were more of the darkness of the night river with no daylight and the soundless dream. From generation to generation, he did it despite knowing that he couldn't do anything. In this world full of despair, they were scattered throughout their innocent lives. Perseverance, aloofness, low self-esteem, plainness, peerless glamour, and even more fleeting years. When you ask them, they all say: I don't have a story to tell you.
