Although Bai Xiaosheng returned the watch given to him by Sebastian to Yun Guangzhi, he did not expect the elder to repay him or to actually help him with his matter.
When chatting with Yun Guangzhi, Bai Xiaosheng noticed that the old gentleman seemed to have a "cold disposition towards everything."
People like Yun Guangzhi have a very hard heart.
This hardness is not because he is not a good person or lacks a sense of justice, but because he can make cold-blooded choices without remorse.
For example, in the commonplace ethical dilemma, "a train is rushing and cannot be stopped, staying on the current track may kill five innocents, switching tracks may kill one innocent," how should one choose.
An ordinary person may find it easy to choose from behind a screen, but would struggle in reality. Yun Guangzhi, however, would decisively make the choice that causes the least sacrifice for the maximum rescue without any hesitation or guilt.
