These seven knowledges were also divided into professions.
It was already very difficult to make one of the knowledges reach the strength of One-Diamond.
However, the current Dong Lei actually had seven knowledges that had reached the strength of a Three-Diamond.
This was comparable to the knowledge of the principals of the four academies, Master Fang Zeng and the others.
Dong Lei had already surpassed Master Fang Zeng and the others. It could be said that he had more knowledge.
Many elders also did not have that much knowledge to reach the Three-Diamond level.
To Dong Lei, entering the academy was only to complete the Sixth Class Advancement Quest.
Moreover, Dong Lei felt that it was just a waste of his time.
This quest was considered very easy.
Most importantly, Dong Lei had obtained a huge increase in strength in the Dark Cellar.
