Description：During the years of Xihe, evil forces were rampant on Zongye Island, where tens of thousands of Tian clan members lived. When the ranger Lin Yu (played by Liu Yanchen) heard about this, he resolutely decided to return to the island to quell the unrest and rescue the Tian family who had been kind to him. On the way, Lin Yu met the mysterious woman Yu Lu (played by Shen Yu) whose identity was unknown. It turned out that Yu Lu was sent by Gao Jing (played by Guo Zhen), the strategist who started the unrest, to confuse Lin Yu, but she saw the good and the evil in the process of getting along with him, and gradually fell in love with Lin Yu. Along the way, Lin Yu encountered various ambushes and assassinations. Yu Lu was almost killed to protect Lin Yu, and Lin Yu, who was cold-faced and warm-hearted, was gradually moved. Finally, with the help of Yu Lu, Lin Yu went through many traps and subdued Gao Jing, and the Tian clan was finally saved.
