The letter Chiyou has sent to the Sun Kingdom would reach there by today, and after reading the letter, sending back a reply would take another day or two depending on the speed of the soldier.
But the letter came back by morning time, what does this mean?
Chiyou commands the soldier to read out the letter that came from the Sun Kingdom, in hope that his friend might have reached the Sun Kingdom safely as he didn't find anything related to Sun Mo in the place where the battle took place.
Chiyou is thinking that the letter that came for him is by his friend Sun Mo who reached the Sun Kingdom safely and then sent a letter back to him telling him about what exactly happened that night because he had sent a soldier to him to ask for helo and this would make him worry if he didn't find him at the battle place.
