"So King Tao Yong is also here, my work has gotten easy I guess" Chiyou says as he remembers the Qi signature of Tao Yong when he first met him, so he knows who is standing in front of him.
And the reason why Chiyou has added 'i guess' in his sentence is because he knows about the marriage between the princess of Tao Kingdom, Tao Xiurong, with the Prince of Xiong Kingdom, Xiong Bo.
He knows that Prince Xiong Bo will fight him, but he is also hoping that he won't need to fight against him because he has no such desires.
"So it's you King Chiyou" Xiong Bo said as he looks at Chiyou who is sitting on his horse.
Chiyou is not holding his bow, he is empty hand right now.
He asks the two brothers "I know your relationship with King Tao Yong, but you have to hand him over to me because he needs to answer a few of my questions before he dies."
