If he followed the transfer to Hokkaido, Police Chief Aoyama Xiu Xin would definitely take good care of him, and his rank would likely hitch a ride on the updraft and get promoted as well.
Nakamura Shinichi didn't hesitate to say, "It would be an honor of my lifetime to follow in the Police Chief's footsteps! I will obey all arrangements from the Police Chief, and go wherever I'm told to go!"
Even though he was about to get married soon, he could always discuss it with Hezi and consider moving to Hokkaido together after the wedding.
"Alrighty," Aoyama Xiu Xin nodded and then added, "I should be going to Hokkaido at the end of January or the beginning of February. I'd like you to go ahead and get a feel for the place, and while you're at it, find a nice place for me to live."
Sending a scout ahead to gather intelligence meant that when he arrived in Hokkaido, he wouldn't be totally unfamiliar with the situation and could quickly get to work.
