Legend has it that Luo Wuzi helped Li Si build the Mausoleum of Qin Shihuang and was named the Tomb King. His descendants were royal relatives, nobles, talented people, and built exquisite tombs, and sent people to guard them for generations. Among them, nine large tombs were revered as the King of Tomb Kings, and were said to be unrobbed for a thousand years and unbreakable for eternity. Their reputation spread all over the world, and they were rich enough to rival a country. The world called them the Tomb King School. After Luo Wuzi's death, it was passed on to his eldest disciple Murong Xiu as the Tomb King, which caused dissatisfaction among the descendants of the Luo family. The two families agreed in front of the emperor that if they cracked the nine strange tombs, they could be reincarnated as the Tomb King. After that, the Luo family left the Tomb King City and set up their own school as the Tomb Attack School. For thousands of years, the two major schools have been at odds with each other, attacking and defending each other. In the world, there are evil bandits coveting the treasures of strange tombs, and the court officials want to get involved in the position of the Tomb King. For a time, the four major forces of attack, defense, theft and capture were surging and murderous, forming a thrilling tomb-faction martial arts world.
