Secret: the Old Man Who Became a Fool

Wang Teng, who traveled to the world of Xianxia, ​​successfully became the new master of the "Sword Dao River" through his unremitting efforts. As a result, before he had a good time, he traveled to the world of the Lord of Mysteries again and became Klein's "grandpa". (Note: "The River of Swordsmanship" is similar to the Sefirot, but its level is higher than other Sefirot.)
