Bai Yutang, nicknamed "Sleek Rat", is a Song dynasty knight-errant from the 19th-century Chinese novel The Seven Heroes and Five Gallants. During the peace talks between the Imperial Court and the Western Regions the four princes from the first batallion publicly paid tribute to the fallen soldiers, but they were suddenly attacked by a group of "stray wolves". Was it the revenge of the Western Regions, the instigation of the Lord and the faction, or other mysterious forces that took the opportunity to make trouble? Bai Yutang was ordered to investigate the case of "Dare Maneater Wolf". With the help of his friend Yu Mo, he quickly discovered the truth of the so-called "Dare Maneater Wolf". They were all controlled by puppetry.
