Lin Fei followed the direction of the spirit vein and investigated all the way along it.
Even though he flew at an ordinary speed, he had mapped out the full length of the spirit vein in just a few seconds.
"This spirit vein is at least two thousand li long."
"Its deepest point lies tens of thousands of meters underground. Extracting the entire spirit vein will indeed not be easy."
"The metallic energy hidden underground is very unusual. It has been interfering with my senses the entire time. I wonder what kind of special ore it is?"
Zhang Pei, Duan Ping, and the others had also finished their investigation.
Every one of them was immensely excited.
It was their first time encountering a spirit vein over two thousand li in length.
They reassessed the value of this spirit vein.
"This spirit vein is more than two thousand li long. If exchanged for cultivation resources, it would be enough for us to cultivate all the way to the Human Immortal Realm."
"With a spirit vein of such length, even some Longevity Aristocratic Families and Celestial Immortal families might not possess one."
"This is a vast fortune bestowed by heaven. We must not let it slip away!"
Zhang Pei stared at Lin Fei's figure. He was about to approach and probe Lin Fei's thoughts.

"That unusual metallic aura underground might be some kind of immortal-grade material of immense value. He may be going after that as well."
No one could remain calm in the face of
