As for alchemy and artifact refining, not to mention the vast initial investment required, just mastering one of them would consume enough time and energy to deter Chu Zheng, who is eager to improve his cultivation.
This is not his area of expertise; the input-output ratio is too low, and it's not worth it.
After much contemplation, a relatively more moderate approach emerged in Chu Zheng's mind.
Find Xue Qing and borrow some cultivation resources.
Considering Xue Qing's current situation, it should be much better than his own. After all, the Martial Pavilion is a major power, and coupled with her talent, the resources she can gather are naturally far beyond what he could collect on his own through relentless scouring.
At present, time is of the essence.
From Yun Tianji, he could learn that the Heaven Burial Palace is already showing signs of opening. He must reach the Eighth Order before the palace opens to qualify for entry.
