Lu Yuan had recently hit a bottleneck with *Celestial Master*.
How should I put this?
It was the same old problem.
Lu Yuan recognized all the characters in it.
But recognizing them didn't mean he could understand them.
It was like being handed an advanced calculus textbook. You'd recognize all the numbers, but could you just do the math?
Clearly, that was basically what *Celestial Master* was like for Lu Yuan.
He had obtained so many books from the system.
And it was this *Celestial Master* that had him completely muddled.
The others were fine.
Whether it was *Craftsmanship* or any of the others, Lu Yuan could understand them.
Why?
Because Lu Yuan was a transmigrator, and he had seen some of these things before.
Even if he hadn't, he could roughly guess or imagine them.
He could figure them out by fiddling around a bit.
But *Celestial Master* was different. There were many things in it Lu Yuan had never seen before.
What was the use of just reading the descriptions?
