Which of the four ancient grave-robbing sects in China is the most powerful?

They are alchemy, mountain sending, mountain unloading and mountain moving. What Mo Jinzong is best at is locating acupoints, that is, finding tombs. He is famous for "dividing gold and fixing points" and is not good at martial arts and body methods. Faqiu school is just like Jin school. He is good at locating acupoints but not as good as Jinmen Sect. It is good at martial arts. Xie Ling School is familiar with traditional martial arts and is good at cracking organizational formation. People who move mountain roads have a Taoist foundation, are familiar with martial arts and organ arrays, and have special arrays and weapons to deal with zombies. Perhaps it is because the knowledge of geomantic omen is not solid, and it is impossible to accurately determine the exact location of the tomb coffin, so they are limited by their own skills, and their best skill is blasting technology.

So what? There is no decision in history, judge for yourself. I can only help you here.
