章 518: Chapter One Hundred Twenty-Nine: Extortion and Blackmail

For ordinary cultivators, tunneling underground is extremely difficult.

Experts from the Mystical Realm can only use brute force to blast open the ground, dig tunnels, and extract spiritual medicines and the like. However, they can only go down to a few hundred meters. They have to be cautious of tunnels collapsing and burying themselves under millions of pounds of rocks. Even powerful cultivators in the "Heavenly Human Realm" of the Fifth Level of Divine Power can only generate the power of ten thousand galloping horses, and being buried deep underground, they would suffocate and die without being able to escape.

Let alone thousands of meters deep.

The underground mud is no match for the seabed.
