To be honest Min Jun Ryun also didn't want to attack Daegu first. But Kim Ye Jun's warning made Min Jun Ryun lose his mind. The man threw a poisoned arrow, which directly hit one of Min Jun Ryun's soldiers. Which immediately made the soldier dry and died. Not to mention, Min Jun Ryun who got the news that there was an attack on Daegu, and made many soldiers fall to their knees. Even though if you remember, Min Jun Ryun and Kim Yeon Seok, no one started attacking Daegu first. They still stay in tents where they take shelter.
Like at this time Min Jun Ryun who was already planning to attack Daegu. Because of Kim Ye Jun's attacks continuously terrorizing Min Jun. Ryun. Either it was a fireball arrow, or maybe a poisonous smoke which could kill people with just one breath.
"I will attack the eastern part of the kingdom." Hyun Ki said. "Because I know that road is the way in and out of Princess Kim Hyo Ra."
