Who can help me introduce The Legend of Qin and the main characters in it? It would be best if it was more detailed. Thank you.

The Legend of Qin was a Chinese web novel written by Ink Fragrance and Copper Stink. The story took place during the Qin Dynasty and described a group of members of the organization called "Quicksand" who fought to protect the country. The founder of Quicksand was Wei Zhuang. He was a mysterious figure with extraordinary strength and courage. The members of Quicksand came from different backgrounds and fields, but they all worked hard to achieve the same goal-to protect Qin. One of the leaders of Quicksand was Wei Zhuang's ally, Stone Hammer. He was an outstanding swordsman who was good at using all kinds of weapons. Shi Chui and Wei Zhuang led the Quicksand members to play an important role in the various crises of the Qin Dynasty. Other important figures in Quicksand included Tian Yan, Xun Zi, Zhong Limei, Li Si, Zhao Gao, etc. These characters all had their own unique personalities and motives. They played different roles in the Quicksand Organization and worked hard to protect the Qin State. The main characters in The Legend of Qin were very rich, and each character had their own unique story and personality, which made the novel very popular with readers.
