The Hole Digging Sect, a famous sect in the world of tomb robbers, is famous for its unique "hole digging techniques." Different from the traditional tomb robbing sect, the hole digging sect is marked by digging ancient tombs. Those who master this skill need to have extremely strong skills and courage. The founder of the sect is said to be a tomb robber named Zhong Tianhao in the Tang Dynasty. During the tomb robbery, Zhong Tianhao used a special technique to penetrate the stone wall of the ancient tomb and quickly entered the depths of the tomb chamber, avoiding many traps. Once this technique spread, it attracted many people with lofty ideals, and gradually developed into a sect with unique tomb robbing techniques and ideas.
