Du Heng had good intentions, but he clearly underestimated the current situation.
Indeed, everyone was very interested in a famous professor like Lan Changhua. However, they also understood that no matter how powerful Lan Changhua was, he was just a professor from the Capital. Furthermore, there was a considerable gap between his specialty and their own.
So, when Du Heng appeared to take Lan Changhua away to rest, these people did not cling too much and let Lan Changhua leave easily.
However, Du Heng himself was left behind by everyone else.
There were all kinds of people: those trying to build connections, those offering greetings, those flattering him, and those directly stating their intentions.
Although Du Heng was reluctant, he couldn't leave while looking upset, so he had to force himself to communicate with everyone.
It was only through these interactions that he realized how ridiculous his earlier assumption during the Q&A session had been.
