Hu Li keep leaping from rooftop tp rooftop. She attracted some attention. The soldiers who are standing guard at the walls notice that there is a boy running on the rooftop and he is wearing the Yamen's work wear. They alert the commander. He give them a command to shot if the boy is heading towards their direction. Meanwhile, on the ground, Officer Zhou have experience Yu Bing's speed have mounted on a horse and chasing after him. He trusted Yu Bing since each time Yu Bing managed to catch a clue and arrest someone. People who hear and see a fast horse in the city, stay clear. He yell for the citizens to clear off in front. Hu Li who is chasing with the speed of her own have noticed that some shiny objects are pointing at her direction. She is sure she can avoid them but she cannot let her prey escape her sight. The guard with the scar arm start to run after he remove the remaining uniform. Hu Li without stopping she run towards the pole which is near the wall area. The commander of the soldiers give the oder to fire the arrows. Hu Li with each turn on the pole manage to doge each flying arrows. She land swiftly and continue to run for the guard. He see that he is being chase so he run with all his might. Strangely he finds Yu Bing moving closer to him and seems like he is loosing speed but he is running till he feels that his lungs are going to explode. At that moment, there is a loud explosion. Hu Li hears screams and cry however she is not to lose her prey. She leap again using the wall to pounce at the guard. The men on the wall watch the young boy run up the wall and with one strong hit on the wall he leap far with his body turning in the air like a cat. They watch him land on a man and kick him on the chest. That man fly backwards and hit on the wall then landed in front of the ground. He becomes motionless. While Yu Bing who have landed gently on the ground look at his prey and look up the wall. The guards are all staring at him. The commander is speechless till Officer Zhou arrives. Shortly the men from Yamen comes and drag the guard away. Officer Zhou and Yu Bing bow to the commander and leave.
"Sir, what did we just ..."
"Nothing. Continue guarding. Go get someone to collect all the arrows that are fired."
Back inside the Yamen, it is chaos. The explosive goes off as usual. There isn't much time to locate where they had hid it and where it will explode. Thus there is quite a few citizens who get injured. The place where the explosion have went off is now blocked. The injured is sent to nearby medical halls that are available to treat the injured citizens. While the injured guard that Yu Bing have arrested is still unconscious. They have him tied up just incase he should pretend to be unconscious and plan his escape route. The fake wall in the jail house is open once again. This time, the men from Yanmen inspect the area inch by inch. By the time they reach the base where they make the explosive, they have run and the materials are already used up. There is nothing to see thus Office Zhou order two teams to go into the tunnels to see where it leads to. While Hu Li goes to look for her little friends. They are hiding in the hay stack in one of the cells.
"Master, after you left, the person with the face cover is back."
"There wasn't any guards at the jail cell once the explosion goes off. That person comes in and feed all the prisoners something in their mouths and leave quietly by the fake wall."
"Check the prisoner's mouth master! There must be something."
Hu Li hurry to pick them up and put them in her shirt pocket. She goes to the nearest prisoner who is laying on the wooden plank bed.
"Hey... are you awake?"
That person is not moving. She hurry to ask one of the guards for the key to open the door. once inside, she check, the prisoner is dead. She ask that guard to go check on the rest. While she press open the mouth of the prisoner. She cannot see if there is anything. They will need the medical examiners to check. Office Zhou comes to know what have happen in the jail cell, his lips twitch non stop. Later the guard who goes around to check as per Yu Bing instructs found them all dead. Officer Zhou is trying to breath in such a difficult situation. The young prince Wang Cao who knows this comes into the cell. He did not scold anyone but look at the cell in dissatisfaction.
"How can this happen under our nose."
They all remain silence till he ask about the one that Yu Bing have just arrested.
"He is in the medical hall. We have tied him up."
Yu Bing suddenly start running. Office Zhou have a shock and he follow within a split seconds. He keep running with Yu Bing till he is out of breath. While Hu Li runs as fast as her feet can bring her. She must reach the medical hall before anything will happen to that prison guard.
Meanwhile at the medical hall, the physicians are busy providing care for the injured. No one is watching the prison guard. A person wearing a dark hooded top step into the shop. The boots are fill with dirt walk slowly towards the prison guard.
