There are indeed four schools of grave robbery in history. The two mentioned in the question are two of them. But it's not Dr. Maoshan, it's Dr. Maoshan. There are two other schools: the school of moving mountains and the school of unloading mountains.

As we all know, the tomb raiders are corps commanders in Faqiu and captains in Mojin. When I heard these two names: corps commander and captain, I knew they were official names. This is a tomb-robbing squad organized by the government, and it is also a leading position. The mound is to dig graves; Touching gold is to restrain property.

How did it come from? Due to the collapse of rites and music in the Spring and Autumn Period, there were reburies. Those dignitaries enjoy life alive and want to enjoy life in another world after death, so they put all the gold, silver and jade used before their death in the tomb. At that time, Cao Cao led the troops to fight and ran out of money. He thought of an efficient and high-return way to get money quickly-robbing a tomb. However, digging someone's ancestral grave is immoral and will be spurned. In order to legalize it, two official positions were invented, namely, a captain and a corps commander. Let them secretly find the graves of some dignitaries and take out the funerary objects in the graves as military assets.

Lieutenant Faqiu is the boss of a captain who touches gold. He has a bronze seal that says "God bless the people and forgive them". The two factions are of the same origin, but those who touch gold are better than Faqiu. They use pangolin claws as amulets, also called gold amulets.

Mountain movers, also known as mountain movers, know some magic and live by strength. Xie Ling Sect, also known as Xie Ling Lux, can be seen from its name. It is also a violent meal.

Later, only the Mojin faction went further, and the other three factions gradually died out.
