With the X-axis representing time and the Y-axis representing emotional value, although the interval was monotonically increasing, there had to be a point where Ren Suo could achieve the greatest emotional value while spending the least amount of time.

In other words, Ren Suo's most efficient emotional harvesting point.

However, finding an emotional harvesting point was not easy. Starting from scratch with strangers would inevitably require Ren Suo to spend a long time getting acquainted with them, so he naturally turned his attention to acquaintances with whom he already had high emotional value.
