When he was asked about what happened after he came back to his homeland, Prince Muyi's expression sank. He was no longer as happy looking, and showed a very serious expression. He frowned as if he were contemplating over something.
He had thought that his father would greet him cheerfully as before, but none of what happened was what he had expected.
The moment his wagon arrived at the capital, the imperial army caught him.
He was taken to his father' side, where he was interrogated. His father had the suspicion that he was going to steal the throne, which was a huge sin for a Prince that had just turned 20. He was not capable of bearing such sin.
Judging from what his father said to him, Prince Muyi was pretty aware that the Imperial Master must have made up some stories.
He had no idea how his father got brainwashed by that man, so much that he trusted him so deeply.
His father still doubted him, even after he tried to defend himself.
