Actually in this case, Han Xiaowu was completely wronged.
First, he had to take care for the mess that his master created. After dumping Concubine Shu's body into Second Prince's bed, he had to ensure that nothing could ever trail it back to Yu Jian. He only chase after Yu Jian after he was satisfied, and at that time, he had been left alone with not even a flash of shadow to be seen.
Originally, Han Xiaowu thought that his master would be waiting for him at the corner. Thus, he had rushed madly with his horse out of the Palace Walls. Then, what did he find?
Nothing! Absolutely nothing at all!
He had rode day and night with minimum rest but still, he couldn't catch up to Yu Jian!
Han Xiaowu felt very aggrieved. Working with Yu Jian required a high level of cautiousness, vigilance and agility. Not only would he dump you everything to clean up, he would also disdain you if you did something wrong.
