The reason they wanted to capture Xiao Wu in Douluo Continent novel 128 was because Xiao Wu was Tang San's daughter and Tang San was Douluo Continent's famous Spirit Master Grandmaster possessing numerous spirit beasts and formidable spirit power. Thus Xiao Wu's existence was seen as a threat and was pursued by many Spirit Masters and enemies. In the novel's 128th chapter, the relationship between the Clear Sky School and the Third Young Master's family gradually became tense while Xiao Wu was chased by the Clear Sky School's enemies and finally escaped to the Tang Sect. The Tang Sect was one of the famous sects on the Douluo Continent, possessing many powerful spirit masters and spirit beasts. Thus, Xiao Wu's arrival had caused turmoil within the Tang Sect. In the novel, some characters in the Tang Sect had emotional entanglements with Xiao Wu, so they hoped to capture Xiao Wu and hand her over to the Clear Sky School to settle the internal dispute. But in the end Xiao Wu successfully escaped and continued to adventure in the Tang Sect, becoming a legendary figure in the Tang Sect.
