Inheritance Cave
"As martial artists were very scarce previously, resources were in abundance, and there were no shortages."
"However, since the cultivation techniques were modified to help the martial artist cultivate, martial arts started to become more and more common, which led to the consumption of the resources."
"Over time, many resources were lost, and many things changed as there were no mediums for us to travel to other lands like the mages."
"Although, with time, martial artists were still able to explore higher realms, the resources became even scarcer. You should know how scarce the resources are here right now."
When Lu Zhen heard this, he nodded his head.
"The 'that' we were talking about is an inheritance cave left by martial artists in the ancient times, which contains invaluable and rare resources of forces from the previous era who couldn't, until now, either due to offending high-level enemies or perishing because of competition."
