Chapter 567: The Urge to Drill a Hole! (2nd Update)

Li Shi's enthusiasm for learning surged as he switched his study project.

He immediately placed his notebook back into the Portable Space, went to the living room to find his backpack, took out his tablet, returned to the study, then logged into the dedicated learning cloud storage, and started reviewing scanned copies of "Recognition of the Jade" and "Complete Version of Jade".

He had already flipped through these two textbooks seven or eight times, and combined with his rich practical experience selling jade and cutting stones, he had a very strong grasp of the content inside.

Thus, his review pace was extremely fast.

Almost reading ten lines in a single glance.

In just two and a half hours, by four fifty in the morning, he had finished reviewing both voluminous textbooks.
