Huangfu Ming

Reluctant to put off his schedule any longer, Lu Yunhe took his leave, leaving Lin Jin to stand in a corner alone as he watched Mr. Huangfu Ming teach his class.

Since he had nothing better to do, Lin Jin tuned in to the lecture as well.

It was a topic on the application of 'spirit energy'.

The lecture content was too profound that Lin Jin only got a subtle gist of it after listening for a bit. A rough explanation of the class would be that they were learning how to maximize the utilization of limited spirit energy when casting spells.

Simply put, it was to tap into a new resource and economize on expenditure.

It had the same concept as managing the household expenditure thriftily. As a human's spirit energy was limited, the main point of this lecture was to teach how one could reap the biggest value by utilizing this limited spirit energy.
