章 514: Chapter 54

Digging underground—it was something easy to talk about, but hard to do.

It was easy to choose a suitable place; you had to avoid soil that was too hard or too soft and have an underground water vein. It was compulsory to dig the tunnel into the right shape to make it convenient to access and transport soil and rock. Moreover, the first priority was to strengthen the tunnel and avoid any collapses while digging.

All of these were things that had to be done, and they had to be done well. Otherwise, it would lead to either failure or accidents while digging.

The most common accident, of course, was collapsing—that was the most common and terrible accident.

The tunnel was buried deep underground. Once it collapsed, almost everyone in the tunnel would die. Even professional adventurers found it difficult to survive in collapsed tunnels because they would die before rescue arrived.
