So, getting back to the point...
No matter what sparked it, Motan had witnessed the situation in White Tower City and immediately detected a potential danger. He felt that in the near future, some very real problems would arise.
For him, it wasn't hard to empathize and realize how ecstatic those who had been waiting for death in despair would be at the glimmer of hope, nor was it difficult to imagine what people might do when they found out that hope might not necessarily come to them.
If he were an ordinary person infected with the plague, in such circumstances, he would definitely seize any opportunity to survive, by any means necessary (a few months ago, when he had fewer ties, he might have too, but perhaps not as explicitly).
Yu Chen's busy figure in the crowd that day, and the astonishment and anger in the eyes of those who were told they couldn't receive treatment immediately, left a deep impression on Motan.
