Dew Tea actually appeared in the palace!
As far as he knew, only one family in the world could make this tea, and it had appeared in only one place.
After receiving the news from inside the palace, he realized something had gone terribly wrong. The fugitive he thought had died on the road had actually made it into the palace. This was very bad news indeed!
At that time, he had ordered a cleanup operation and only then discovered that someone had slipped through the net. Later, when his men went to search, they found nothing. When they pursued the matter further, they found a corpse, which upon inspection was said to be that very fugitive.
To be safe, he had secretly followed up on this matter for a long time, only calling it off when there were no more slips.
Unexpectedly, the supposedly foolproof plan had gone awry.
