Inside the Cold Iron Ore wall torn open by Sword Qi, an ice-blue glow spread and blossomed.
Within that radiance, Lin Lin's figure was also cast in ice-blue hues.
Faced with this situation, Lin Lin's first reaction was not to step closer and investigate.
Instead, he instinctively circulated his Inner Breath to protect himself.
Then, with a tap of his toes, he unleashed his movement technique at full speed and rapidly retreated from the glowing Cold Iron Mine wall.
Ever since his first day working at the Cold Iron Mine, he had used the Cold Iron Mine walls deep within the cave as aids to his cultivation, digging into them with all his strength.
Although his digging progress had initially been extremely slow, as time passed and Lin Lin's martial arts grew stronger, his speed at excavating the Cold Iron Mine walls had also steadily increased.
By now, although Lin Lin had not deliberately rushed his progress, he had still dug this mine shaft several kilometers downward at a slant.
When a glowing substance suddenly appeared hundreds of meters underground, it might simply be something luminescent, like glow-in-the-dark powder or luminous pearls. It might also be some precious mineral or gemstone that could make him rich overnight.
But an even greater possibility was magma leaking from the depths of the earth, or highly radioactive material that could cause cancer upon contact.
Though he had cultivated martial arts diligently and possessed a body far stronger than an ordinary person's, whether he could withstand these dangers of nature was still unknown.
Lin Lin did not want to pay a painful price for a moment of recklessness, so with everything still unknown, he chose to avoid the danger for now.
Lin Lin continued retreating.
