Tomb Keeper's Thousand-Year Sword Shadow

In 221 BC, it was a cold rainy night at the northern foot of Lishan Mountain near Xianyang, the capital of Qin. Protagonist: "Shi", a taciturn young tomb guard who belongs to a mysterious "Tomb Guard" organization. He has strong skills and masters a set of ancient swordsmanship called "Zhenyue Sword Technique". Incident: A group of well-equipped tomb robbers attacked a burial pit built for Qin Shihuang's mausoleum at night. Shi fought alone and repelled the enemy with his exquisite swordsmanship. However, the leader of the tomb robbers left a strange message before escaping: "You cannot guard the things in Emperor Qin's tomb. The world will soon be in chaos." Suspense: Shi found a strange bronze token engraved with the word "Yan" on the tomb robber, which made him realize that things were not simple.
