"I didn't expect you to discover it so quickly."
Lin Hongyi looked at the barren hills below and said:
"These hills are called the Sinking Iron Hills. The underground is rich in Black Sink Iron and Profound Weight Stone ore... so the gravity here is far greater than the outside world. Black Iron City developed because of these mineral resources."
Luo Feng nodded, as Black Sink Iron and Profound Weight Stone both increase the surrounding gravity, no wonder the gravity here is so peculiar.
As they continued deeper, the gravitational pull became increasingly intense. An hour later, Lin Hongyi wiped the sweat from her forehead, exhaled a warm breath, and said:
"Black Iron City is not far ahead, Luo Feng, let's go down."
In such an environment, even as a Martial Artist in the Spiritual Rotation Realm, aerial flight was a considerable burden.
"Okay."
Luo Feng nodded, and the two descended onto the road and began walking.
