Clearly, the dean meant that Ren He had passed, and moreover, he was going to study painting directly under him. One must know that Dean Richard was a doctoral supervisor...
Of course, this didn't mean that Ren He could just skip over the bachelor's and master's degrees and become a doctor directly. There was no such rule, but do people in the art circle really care about diplomas? Rarely does anyone use a diploma to distinguish the artistic merit of an artist.
In Arthur's eyes, he realized that Ren He had metaphorically ascended to the heavens in one step. This was actually the same in the piano circle; being a student of a master was also a very important matter. At the very least, the influence was innate, and one wouldn't remain unknown forever.
In the field of painting, as long as one's art was good, diplomas were actually secondary.
As long as Ren He studied diligently under Richard, ascending to the heavens in one step wasn't a difficult task.
