In the forty-seventh year of Wanli in the Ming Dynasty, the war in Liaodong was intense. Near Chongwen Gate, one of the nine gates in the capital, there is a man who is over 40 years old and is responsible for patrolling the streets at night. That night, as usual, he walked along the alley carrying a lantern and saw a huddled figure at the back of the pickle garden. He took a closer look and saw a bloody waistband falling out of the man's arms. It turned out to be the brand of Jinyiwei Beizhen Fusi. Shen Lian bent down to pick it up and heard rapid footsteps coming from the other end of the alley.
