Kang Chen said two words to Ming Mei: "Owe..."
Qi Jiu and Kang Chen got acquainted several years ago, to the point where they might as well have met when they were butt naked. However, they did indeed meet during their childhood, so you could say they were childhood acquaintances.
Because the factions of the two families were different, they didn't play together as kids.
When they grew up, Kang Chen joined the military two years earlier than Qi Jiu.
By the time Qi Jiu joined, Kang Chen had already made his mark with impressive performance and reputation.
Qi Jiu was unsatisfied, so the two had been rivals for many years.
Qi Jiu knew well in advance that every time he went to find Kang Chen, he was bound to get a good beating.
But Qi Jiu still liked to show up for a fight every once in a while, despite the constant rivalry between them over the years. As it turns out, their relationship wasn't as incompatible as outsiders thought.
