It actually saved the Night Lord a considerable amount of effort.
Su Mo had this intention, simply because he was not the one to suffer the pain of standing and talking.
As he was pondering, he heard the Night Lord speak softly:
"This person is both a mentor and a friend to me."
Su Mo's eyebrows raised slightly: "Oh?"
Both a mentor and a friend...
That phrase is quite interesting.
This person should not be the Night Lord's teaching mentor; otherwise, how could he be called a friend?
Yet, he had taught something to the Night Lord.
But what exactly did the Night Lord learn from this person?
And how are they friends?
As thoughts emerged in his mind, he heard the Night Lord ask coldly:
"When it comes down to me, who are you?"
The Night Lord was genuinely uncomfortable not asking this question.
Although he also knew that the little game the two of them were playing, in itself, held little significance.
