How do people go underground to look for riches?

People go underground to look for riches by engaging in activities such as mining, drilling, or excavating. These activities involve digging deep into the earth's surface to extract valuable resources such as minerals, metals, oil, or natural gas. Miners and other workers use specialized equipment and tools to access underground deposits and extract the riches that lie beneath the surface. This can be a dangerous and challenging process, but the potential rewards can be significant for those who are successful in their efforts.
