City: Attack, Fat House

　　What is an 'urban drainage system'?

　　simply put.

　　Urban drainage system is an engineering facility system used to treat and remove urban sewage and rainwater.

　　It is an integral part of urban public facilities.

　　The urban drainage system usually consists of drainage pipes and underground cement channels for sewage treatment and rainwater diversion.

　　If there is no such drainage system.

　　A single torrential rain can flood an entire city.

　　This is no joke!

　　very few people know.

　　The drainage channel under the city, like an underground palace, runs through the entire city.

　　At some nodes, there are also underground warehouses for maintenance and sewage workers to rest and store tools.

　　Such a warehouse.

　　As long as you stock up on enough food, fresh water, and oxygen.

　　Enough to live underground for a while.

　　Why use oxygen?

　　Because the underground drainage system will breed some harmful gases.

　　Some are flammable and some are harmful to humans.

　　Why did Xiao Yao think of Wang Dalong hiding in the urban drainage system?

　　First of all, no people were found in the sky and ground of the city.

　　Secondly, Wang Dalong robbed the beauty salon and some medical equipment.

　　Among them are two small oxygen cylinders.

　　Even if Wang Dalong really wants to do plastic surgery for himself.

　　One oxygen cylinder is enough.

　　There are places where two oxygen cylinders are needed.

　　Can you hide people?

　　Only underground!

　　of course.

　　This is just one inference.

　　more accurate inferences.

　　It is because Wang Dalong has not committed crimes in the past before being imprisoned in the detention center.

　　Worked as a sewage worker for a month.

　　even so.

　　Most normal people don't even think about it.

　　Someone is actually hiding in the city drainage system.

　　It's a pity that Xiao Yao is not a normal person, he has a system.

　　The city's police searched and began to investigate the underground.

　　It was shocking and unexpected.

　　Sure enough, the police found a clue in a warehouse in a passage somewhere underground.

　　Wang Dalong did appear here before.

　　And Han Gengcheng's wife also appeared here.

　　But Wang Dalong was too alert.

　　He was discovered when the police started searching underground.

　　How did he find out?

　　a fishing line.

　　a bell.

　　This is a very simple defensive warning 'cordon'.

　　As long as someone triggers this warning line.

　　Wang Dalong, who was hiding in the distance, could immediately pass the bell to know that someone had entered the ground and escaped calmly.

　　in the army.

　　This is one of the simplest means of defense.

　　A bit more advanced.

　　Some special forces can use a silk thread and a bullet casing to make this kind of cordon.

　　Fortunately.

　　There are no explosives around Wang Dalong.

　　otherwise.

　　He can set trigger bombs at the cordon.

　　even so.

　　The armed police who searched the ground were also frightened.

　　By the time the warehouse was found, it was already empty.

　　Where did Wang Dalong take Han Gengcheng's wife?

　　He came to the ground from the sewers.

　　Hijacked the business hall of a secondary branch of a bank!

　　When Xiao Yao came outside this small bank.

　　The military and police have surrounded the place.

　　shouting in progress.

　　"Wang Dalong, you are already surrounded, put down your weapons immediately..."

　　What a familiar scene?

　　Xiao Yao sighed.

　　once Upon a time.

　　A scene you only see in movies and TV shows.

　　Now you can be there yourself.

　　Wang Dalong, is it better to prepare?

　　Grandpa is here! .

Chapter 60

　　At nine o'clock in the morning, the sky was overcast.

　　The streets are on alert, and the military is on alert.

　　"I'll let your mother force you!"

　　In the bank surrounded by circles, Wang Dalong, who was holding gauze all over his face, was holding a pistol at a woman's head, and shouting with savage eyes, "Shut up for me, and bring some food over here immediately. , I'm hungry now, and if I can't see anything to eat within ten minutes, I'll start killing people!"

　　The banking hall is already open.

　　There are also customers for business.

　　Now gathered around Wang Dalong, there are six bank staff, five customers handling business, including the woman who was pointed at the head by Wang Dalong with a gun.

　　A full twelve hostages.

　　Eleven of them had gauze wrapped around their faces!

　　Even more speechless.

　　This Wang Dalong only used a bag of flour and a bucket of mineral water.

　　Easily put a layer of 'coating' on the doors and windows of the bank hall.

　　So that the outside military police can't see what's going on inside.

　　Snipers are useless.

　　Forcibly rescue the hostages?

　　Don't make trouble.

　　Those were twelve hostages, and the death of one was a big deal.

　　If all died in violent rescue.

　　Guess what the consequences will be?

　　Even more speechless.

　　Monitored by mini robot.

　　The police outside have been about to probe the inside of the bank.

　　At this time, Wang Dalong and all the hostages were standing in the bank counter.

　　To know.
