Bond City was destroyed overnight, and young Luo Kai crawled out of the sea of blood. He was rescued by the mysterious old man Mel, and met a knife-wielding boy and a sword-wielding girl in Tianmen City. He had friends and a name for the first time. At the end of the wind and snow, under the giant tree in Fanghua City, the master said to him: There is no need to hide it in the future. What he didn't know was that thousands of miles away, the sister he vowed to find was waiting for him at the end of time.
