The butler was indeed holding back his ire.
Some things couldn't be accomplished with just a bit of effort over a short time, like the airplane modification style he dreamed of.
Another example was the investigative progress on the construction site incident.
With many things going awry, of course, the butler had his emotions.
However, in Feng Yi's presence, the butler still wore a proper or kindly smile. This wasn't feigned; seeing Feng Yi lifted the butler's spirits somewhat.
And when Feng Yi wasn't around, the butler wouldn't wear a stern face openly, but that subtle, indifferent demeanor was very pressurizing.
The employees were quite tactful; they wouldn't loiter around in front of the butler when the boss was away.
That day, the butler was still walking around the courtyard with pruning shears in hand, deftly clipping away wherever plants grew too wildly.
His eyes were sharp and bright, sweeping inch by inch over the colorful flora.
