Good deeds don't always lead to good rewards, but helping others very likely benefits oneself as well.
Whether it was then or eight hundred years later, there weren't many people with whom he, Lin Yifei, could have in-depth conversations. In fact, his understanding greatly diverged from the knowledge of others.
Others always talked about trivial matters, while he discussed the philosophy of heaven and man, unavoidably causing discomfort. To avoid seeming too peculiar, he often chose to remain silent.
In the midst of lively crowds, he was solitary.
It wasn't until he started conversing with Shen Yue that he felt truly exhilarating.
