Yizhang's coal mine is very profitable. And the money is easy to earn! But the average person is too stupid to get access to, or impossible to get, the mineral rights. Even if it is obtained, the coal mine that should have made a lot of money will become unprofitable because the local underworld forces charge a lot of protection fees. Among them, I, known locally as Nanba Tian, Qingyun is the most conspicuous. He owns several illegal small coal mines and employs a group of thugs, my brother, to protect the coal mines in all directions. Forcibly collect protection fees from other people's coal mines. If you fail to meet his requirements, you will be beaten or even killed! If you still feel the atmosphere, use explosives to blow up the other coal mine and rob the other equipment and machinery.
