Someone once said, "To test the modernity of a city, a heavy rain is all it takes." If there is no standing water on the streets of the city, it means that it is an advanced city; If there is a small amount of standing water, then it is a medium-sized city; If there is too much water, and even items such as wooden basins can be drifted, then the city is developing, and it is too late to take care of the underground drainage system with only the high-rise buildings that can be seen at a glance. ”

The Song Dynasty did not have such an advanced consciousness, and did not think of using underground channels to show its civilization, all out of practical needs.

Jingshi Kaifeng, geographically located below the Yellow River, the flooding of the Yellow River in ancient times almost became the norm. In the summer, nearby rivers begin to rise and pour back into the city. If Kaifeng did not have a good underground channel to drain the flood, it would have been flooded.

Therefore, from the Later Zhou Dynasty, the imperial court paid great attention to the flood discharge problem in Kaifeng. After Zhao Kuangyin added the yellow robe, Kaifeng was designated as the capital, and the construction of underground channels was the most important project. After several years of repair, the underground of Jingshi can not only drain water, but also run horses to build houses.

According to the History of the Song Dynasty. According to the records of the canal chronicles, the open channel on the ground of Kaifeng has an "eight-character water outlet": "the inner and outer eight compartments create an eight-character water outlet, and the rainwater flows into the canal very well", and the underground is "Biandu is wide and flat, and the ditch is used to run the water." ”

These projects ensure that Kaifeng will not be flooded with water, and it is impossible to fish on the street when it rains, which is a real conscience project. Although it cannot be compared with the Great Wall of Qin Shi Huang, the degree of benefiting the people is not bad.

The sixth volume of the "Notes on the Old School Nunnery" written by Lu You of the Southern Song Dynasty says: "The ditch of the Jingshi is extremely deep and wide, and the outlaws hide in it, and they call themselves 'worry-free caves'; From the beginning of the country to the prosperity of the army, there are often them, although they can not be absolute. ”

It means that the underground drainage system of Jingshi is deep and wide, and people can live in it, and there are many outlaws hiding in it, and they call this "worry-free cave"; There are also some traffickers who abducted women and hid here, also called "Ghost Fan Tower", which existed from the beginning of the dynasty to the time of war, although the imperial court often sent people to clean up, but they could not be eliminated.

Fan Lou is a very famous entertainment place in Bianliang, Tokyo in the Song Dynasty, also known as "Alum Tower". At that time, it was comparable to the existence of the Burj Khalifa. The building is three floors high, the fifth floor is facing each other, can accommodate thousands of people, can eat and drink, can also sleep in flowers and willows, it is the place where the children of the rich family in the city seek pleasure, outsiders enter the Beijing Division, if you don't go to Fan Lou to play a trick, you can't count as having seen the world.

The Fan Tower on the ground is the landmark building of the Beijing Division, and the Ghost Fan Tower under the ground is a place where the filth is hidden, and it is the dark side of the prosperous Beijing Division.

When Fan Zhongyan knew about Kaifeng Mansion, he only severely cracked down on the lawbreakers on the ground, but could not do anything about the criminals living underground. Later, when the famous Kaifeng Mansion Yin Baozheng was in charge of Bianliang, he could only be like a whack-a-mole, waiting for the bad guys to show their heads before they could go down with a stick. As for sending troops into the underground to clean up, they did not once.

If you don't want to, you can't.

The first difficulty is that the suspects have lived here for a long time, are very familiar with the terrain inside, and are well versed in the set of "I will run when the enemy comes, and I will return when the enemy retreats", and law enforcement officers who are not familiar with the terrain cannot find them at all;

The second difficulty is that the Kyoshi is above, and heavy weapons cannot be used underground. The Song Dynasty already had powerful artillery, if this was in the field, firing a few cannons would solve the problem, but who would dare to fire artillery in the Ghost Fan Tower? What to do if it causes a collapse? The emperor was the first to ask them about their sins;

The third difficulty, in addition to the channels under Kaifeng Mansion, there is also the ancient city of the Warring States Period, there is a folk song that "Kaifeng City, the city is stacked on top of each other, and there are several cities buried underground", which undoubtedly increases the difficulty;

The fourth difficulty is that although there are many criminals in the Ghost Fan Building, there are more homeless poor people. To a certain extent, they are the hostages of the suspects, and the law enforcement officers do not dare to push too hard;

The fifth difficulty, if the clean-up is successful, then how will the people inside deal with it? With so many people suddenly appearing, the imperial court is unable or unwilling to take care of their food, clothing, housing and transportation, which will cause an even greater security crisis.

In fact, in the beginning, most of the people living in the sewers were poor people. Or due to disasters, or due to illness leading to bankruptcy, homeless. He was reluctant to leave Bianliang, which he was accustomed to, so he became a domestic servant or a small trader who occupied the road. At night, they live in the sewers.

No matter how high the quality of the sewers in the Song Dynasty was, the sewers were the sewers. In addition to the usual discharge of domestic sewage, every rainy season, it will inevitably become a Zeguo. Who would live in a nice, damp and smelly sewer?

But after a long time, the "heroes" who committed crimes on the ground gradually discovered such a paradise. Although the accommodation conditions are poor, the victory lies in the government's unwillingness to govern, and there are many weak citizens who can be oppressed. By the time the government has made a ruthless effort to govern it, it has already been implicated and cannot be easily removed.

Last year, Zhang Xing, the head of the forbidden army, was drunk and killed, and he deserved to die according to the law.

That Zhang Xing was very brave, slashed and killed several people who went to arrest him, and escaped into the sewer along with a few ruffians. Relying on his ruthlessness and force, he brought together the green skins that were originally powerful in the sewers. Those who obey him will naturally eat and drink spicy, and those who do not obey will either be expelled from the sewer or evaporate from the world. Anyway, according to the spaciousness of the sewer and the ability to drain the water, dozens of people will be thrown into it, and there will not even be a splash.

A gangster who had read a book for a few days suggested to Zhang Xing, who was carrying the handle: "I live in this waterway all day long, although I don't see the light of day, but I am happy and carefree all day long, which can be called 'worry-free hole'!" ”

As a result, the Bianliang sewer has a very fairy name - Sanssouci Cave.

Zhang Xing was very envious of the luxury of the Fan Building, and he also forcibly occupied several beautiful women, singing, dancing and drinking all day long, which was really happy. Therefore, it is also called the Ghost Fan Building.

Thanks to Fan Zhongyan's crackdown, the green skins who escaped the legal net came to vote one after another, and the strength of Sanssouci Cave rose sharply, and nearly 100,000 people lived on their noses at the peak. Zhang Xing once said proudly: "This Bianliang City is the world of the official family during the day." At night, it's my Zhang's world! Some flatterers call it "the son of the night".

This year, Fan Zhongyan was demoted out of Beijing, and the Kaifeng Mansion was leaderless, and the crackdown on these underworld forces was much looser. For a while, the warriors of the dungeon ushered in their own spring, and the disaster was even more violent. Also, how can a plate of scattered thugs do bad things with an organized society, financial resources, and even a protective umbrella?

Since they are all sons of heaven, simply killing people and selling goods, forcing good people to become prostitutes, and abducting and trafficking in human beings are not enough to show their prestige. Didn't Taizong order the painter to paint on the spot to record his majestic appearance when he was fortunate to be in the middle of the week! Let's play big, too.

It just so happened that there was a maiden, whose maiden name was Bihui, and her flower name was five girls. Although you are a clan, you are far from Zhao Zhen's lineage, the descendants of Taizu's cousins, can you still expect the people of Taizong's lineage to take care of you? And Taizu has been founding the country for a hundred years, and there are tens of thousands of clans, and this distant relative committee really can't take care of it. It's just to give some rewards when worshipping ancestors. On weekdays, doing some business under the banner of the clan is just more famous than ordinary people.

These five girls gave birth to a good skin, and they were not willing to let their peerless appearance wither, so they often interacted with some frivolous officials and gentry. Accompany to eat and drink, accompany to have fun, if the price is right, it is not impossible to accompany it.

Zhang Xingjiu heard the good name of the five girls, and his heart longed for it. But how can you, the head of the forbidden army, a rude man who doesn't even have a grade, be able to get into the eyes of the fifth girl, the noble daughter of the clan?

After unifying the Sanssouci Cave, Zhang Xing missed the legendary peerless beauty, and thought of inviting the five girls to come to the Sanssouci Cave to play for a few days. Euphemistically asked someone to invite him with a lot of money, but was rejected by the five girls with "the concubine body is like a willow and does not dare to serve on the pillow seat".

Okay! This is not to give me face! When it spreads, people's hearts will be scattered, how can we bring this team? Zhang Xing held a grudge, and on impulse, he wanted to rob people with open fire, but fortunately he was dissuaded by his subordinates.

The five girls also knew that Zhang Xing was evil, and they were afraid of accidents, so they were very careful when they entered and exited.

But as the saying goes, if you don't shoot a thief and steal, you are afraid that the thief will remember.

One day, Qingpi, who was in charge of stalking, reported that the five girls were scheduled to have a banquet with so-and-so somewhere tonight. Zhang Xing sent a few Qingpi who looked a little human, disguised themselves, and carried the sedan chair to the fifth girl's house in advance, pretending that so-and-so would send someone to pick them up.

The five girls didn't know about the deception, and got on the sedan chair very happily. When I realized that the situation was wrong, I was already in the Sanssouci Cave.

The five girls were also veterans of the battlefield, and when they saw that they couldn't get out, they quickly calmed down, and they were not panicked like ordinary women, and they would not seek death and life because of their chastity. I was afraid that Zhang Xing would harm her life, so she tried her best to have fun in every way, and held an uncovered meeting with Zhang Xing and the leaders for more than ten days.

said that on that day, after Zhang Xing kidnapped the five girls, the sedan chair of the main owner also arrived. After asking, the family knew that there was an accident. After careful searching, someone saw that the sedan chair was carried into the Sanssouci Cave. His father mobilized a group of benefactors of the five girls, raised four million money, launched relations, and pressured Kaifeng Mansion, intending to rescue his beloved daughter from the clutches of the devil as soon as possible.

When Zhao Yunrang, the chief priest of the great sect, learned about it, he felt that it hurt the royal face, and he was also very annoyed. After the emperor Zhao Zhen was revealed, Dali Temple cooperated with the Criminal Department to take charge of the case and launched a forbidden army to search for Zhang Xing. And Fu Bi, who was temporarily in charge of Kaifeng Mansion, was very unlucky to take the blame, was trained to be a dog blood sprinkler, and solved the case within a limited time.

More than ten days later, the good news came that the traces of the five girls were found in a ruined temple outside the city.

According to the five girls, they couldn't remember where they came or where they went, but they knew that there were no windows there. After suffering a lot, she begged for words to survive.

Fu Bi didn't care if the five girls' statements were true or not, he just wanted to know if he could find out Zhang Xing's lair. But seeing that the five girls don't seem to be fake, they can only extinguish the idea of using the victim's testimony to catch Zhang Xing.
