Xianmen Mine Slave: Start by Listening to the Earth Veins

The protagonist Chen Yan possesses the worst Five Elements Soul Root and is sold into the Chixia Sect mine. Others relied on spiritual elixirs, exercises, and teacher training to cultivate immortality. He couldn't even keep a complete spiritual stone privately, so he could only go deep into the mine every day to dig out cultivation resources for the immortal sect. After a cave-in, he began hearing sounds in the rock formations. The ore echoed, the cracks murmured, the earth's fire was like breathing, and the spiritual veins buried for thousands of years emitted a heartbeat in the depths of darkness. At first, he just wanted to find a safe mine tunnel and take his sister out of the mine. Later, it was discovered that the spiritual veins of the entire world of immortality were being drained by some kind of force, and the father who disappeared that year was the first person to discover the truth.
