Sigu 'an is a character in Mao Ni's novel The Joy of Life. His real name is unknown. One of the four great masters, the blade master, the guardian of Dongyi City, is the real master of Lu Jian and Taiping Bank. Since childhood, I like to squat under a tree and watch ants for a day, and I am regarded as a fool by the world. One day when I was watching ants, I met Ye and Wu Zhu.
Gu Si sword is a great master, the strongest level in Yunian Qing, far more than doing. In addition to Gu Si's sword, there are also messengers from Kulian, Ye, Wu Zhu and Wuming Temple who have reached this level of strength.
Four Gu Jiegang's disciples later took orders from Fan Xian:
Four disciples were handed down by Gu Jian, and twelve of them were all with the strength of Do. The main appearances are the first disciple Yun Zhilan (grade nine), the second disciple Li Bohua (actual controller of Taiping Bank) and the closing disciple Wang Xi (grade nine).
After Sigujian's death, according to his last wish, Yun Zhilan served as the Lord of Dongyi, leaving Lu Jian to restrict Fan Xian, and the rest of his disciples took orders from Fan Xian. Three disciples and four disciples have fought against Fan Xian and Shadow, knowing that they will look after the sword.
