Paperboy

Once a police academy graduate—Xu Qian, woke up and found himself in jail. He was to be banished to the borderlands in three days...
Stuck in this inhumane society, his initial goal was just to be a rich man and pass his days in relative safety.
…
Many years later, Xu Qian recalled the events of the past. His enemies and friends were dead, there was nothing of them left but bones.
The rolling Yangtze River flows east as the waves wash away the heroes. 
Success or failure, wrong or right; matters little, it might?
The lush mountains remain while the sun sets every night.

    The three-day day patrol passed just like that. That night, Xu Qi 'an, song tingfeng, and Zhu guangxiao formed a team. They were wearing black uniforms and short capes. A Gong hung on their chest and a knife hung on their waists. They walked on the streets of the inner city with ease.


  The night gradually cooled, and the flowers fell to the ground and turned into frost.


  The capital was silent at night. It was winter, and there were no chirping of insects or chirping of birds. It was so quiet that Xu Qi 'an felt like he was in a leisurely countryside.


  From time to time, he could hear uniform footsteps and the clattering of armor plates.


  They were the Imperial saber guards who patrolled the city.


  After patrolling the streets for an hour, song tingfeng and his two colleagues jumped onto the top of a small building and looked down at the crisscrossing streets.
