Zhao Jinglan, the young master of the "Zhenyuan" escort bureau in the northern border, is a young hero, famous for his "Meteor Iron Shocking Dragon Spear" at the border. On the way to escort the "Dragon Scale Gold" tribute darts related to the northern border defense, his father and brother were robbed and killed by the mysterious "Zhulong Sect". All the darts were lost, leaving only the poisonous darts engraved with the "Zhulong" mark. The imperial court was furious and raided the escort bureau for dereliction of duty. The entire Zhao family was wronged. Jinglan, bearing the name of "criminal", fled to the end of the world with his young sister Zhao Ling'er. In order to avenge his grievances and find out the truth about "Zhulong", Jinglan was forced to escape into the rivers and lakes, and was involved in the whirlpool of court intrigues, rivers and lakes disputes, and alien invasions. He had many adventures and achieved great success in martial arts. He gathered the like-minded "Jinglan Guards" and became the "Reverse Scale" Zhao Jinglan, who was famous in the world. However, the road to revenge is bloody, and the former hero gradually becomes evil. When he finally found out that the man behind the scenes was "Zhu Jiuyin", the orphan of the previous dynasty who was hiding deep in the palace, intending to overthrow Dayin and establish the theocratic empire in the name of "Zhu Long", he found that he had become the most critical and dangerous pawn on the chessboard of power. In the final "Battle of Longyuan", Jinglan slashed Zhu Jiuyin with his hand, but due to losing control of his power, he stepped through a mountain of corpses and a sea of blood to save the people, and was pushed to the dragon's throne. During the enthronement ceremony, the dragon robe was added to his body, and when all the people bowed their heads, he put down the butcher knife and chose forgiveness. However, he was pierced through the heart by the true heir of "Zhu Jiu Yin" who he trusted most and had been lurking around him with a dagger quenched with the poison of "Zhu Long". Jinglan fell with a smile, leaving behind a dynasty with unrest, unsolved mysteries, and legends and controversies that will last forever. His blood dyed the dragon chair red, and also dyed the "Candle Dragon" jade pendant with reverse scales red, and it ended in shock and lamentation.
