The combination locks of later generations, most of which are decimal, seem to be difficult, but in fact, they are only for some old thieves, but that's it. As long as it's violent enough, it's not hard to break.

But the tangram lock, but it is twelve, has seven gears, and there is gunpowder in it, and once it is brute-forced, it will explode, cutting off any possibility of brute-force cracking.

What is a password?

If you go down one by one, you don't know what year and month it will be broken.

Li Mu touched his chin, looking sad.

"Can you break it?" asked Li Mu.

Liu Qingchan said: "No. I can't break it. It's best to ask the disciples of the Shengong Pavilion to make a move, but the disciples of the Shengong Pavilion will not make a move, this is the rule!"

"How much does it cost to make this Secret Pavilion?" Li Mu asked.

Liu Qingchan estimated: "It is made of 100 steel, equipped with a tangram lock, and it costs at least five hundred taels of silver!"

Li Mu felt a toothache: "It's really expensive!"

One tael of silver is equal to two hundred yuan in the Hereafter, and five taels of silver a year for ordinary people is enough to live a prosperous life.

Li Mu is the county order, 45 taels of silver, 20 taels of rice, if you add 1,200 taels of silver, it is equivalent to an annual income of 600,000 yuan. This is not an annual income of 600,000 in 2020, but an annual income of 600,000 in 1990.

But a safe, which is his half-year income, is simply too tyrant.

Li Mu thought about it, took off the "Picture of Emperor Yan Shooting the Tiger", observed it carefully, and stepped forward to smell it again, Liu Qingchan wanted to ask something, but he could bear it.

"Mrs. Zheng, give me a glass of wine!"

Li Mu said suddenly.

"Yes, sir!" said Mrs. Zheng left, bringing a jar of wine a moment later.

Li Mu stepped forward, tore open the seal, stepped forward and smelled it, it was pure rice wine, poured it into a bowl, and then poured a glass of wine on the "Emperor Yan Shooting the Tiger Picture", and suddenly the picture scroll became wet.

Liu Qingchan said: "What are you doing here?"

"Try it!" Li Mu said, his eyes suddenly lit up.

I saw blood-colored red letters appear on the scroll.

"Chou, Mao, Chen, Shen, Wu, You, Yin"

Liu Qingchan and Li Mu glanced at each other with joy.

"Test it out!"

"Good!"

Liu Qingchan stepped forward in person, turned the gear, turned to the corresponding position, and was about to step forward to open it. Li Mu stepped forward and said, "Be careful of the poisonous crossbow!"

"Yes!"

With ten thousand cautions, Liu Qingchan opened the tangram lock, and when it was opened, he quickly dodged away.

Just thinking too much!

The moment it opens, it's safe.

I thought about it a lot.

It was not large, with twenty gold bars, some jewels, and an account book.

Li Mu's eyes lit up, and he gave up everything else and took the account book directly.

I opened this ledger and only roughly flipped through it, and it vaguely felt wrong.

"This account book, the official took it back!"

Li Mu said.

Mrs. Zheng wanted to say something, but in the end she could only nod.

Liu Qingchan said: "Lord County, there is this!"

She held a token in her hand, made of a thousand steels, with the word wind and rain on it, and the copper twelve written on the back.

"What is this?" asked Li Mu.

Liu Qingchan opened his mouth to say something, but he just looked at Mrs. Zheng and the three concubines, and suddenly fell silent, and said after a while: "Lord County, let's talk about it in another place!"

"Good!"

Li Mu nodded, and when he arrived in another room, there was no one around.

Liu Qingchan said: "Brother of retreat, this token is called Wind and Rain Order!"

"What is the meaning of the wind and rain order?" asked Li Mu.

"Five years ago, a killer organization appeared called Wind and Rain Building. Fengyulou, five years ago, caused a lot of killings on the rivers and lakes, and countless strong people were assassinated and died. It's just that I walk a lot at night, and I will always meet ghosts, and it is said that I offended a great grandmaster, and was killed by that great grandmaster, and suffered heavy casualties, and then became low-key!"

"Wind and rain building, killers are divided into levels, gold medal killers, silver medal killers, bronze medal killers!"

Liu Qingchan took this token and said leisurely: "This wind and rain order is the killer token, and it is its symbol." In many moments, the killers do not know each other's identities, only recognize the token but not the person, only the top executive, know the identity of each killer! This token shows that Zheng Butcher is a Fengyulou killer or a bronze killer, and his number is the twelfth!

"No wonder this is the case, it turns out that this ledger is a murder ledger!" Li Mu said.

Liu Qingchan also looked at the account book, which recorded a person's name, origin, living habits, etc., and some people had a big fork in the mountain, representing death.

This is the ledger, and it is the ledger of murder, and it is the ledger of death.

I originally thought it was just a murder case, but I didn't expect that the killer organization involved in the rivers and lakes would be involved.

Li Mudao: "Wind and rain building, what are the characteristics?"

Liu Qingchan said: "Low-key is the biggest feature of Fengyulou. The wind and rain building, the moment when you take over the task and kill the enemy, is often silent and low-key, creating the illusion of natural death. After a lot of examinations, the conclusion is that it is just a natural death!"

"Secondly, it is hidden! Who knows how many killers there are in the Wind and Rain Building, who the internal structure is, and who its owner is. ”

Li Mudao: "Fengyulou, why was it founded?"

Liu Qingchan said: "I don't know this either. However, I speculate that the establishment of the Wind and Rain Tower is mainly for two purposes, one is to collect money, and the other is to collect intelligence!"

Money is not everything, power is.

But power wants to be omnipotent, but it can't do without money. Once money and power are combined, they can be terrifyingly destructive.

As for gathering intelligence, there are many moments when intelligence determines success or failure.

"Who do you think can build the Wind and Rain Tower?" Li Mu asked.

"This ...... Could it be that you retreated, what did you think of?" Liu Qing said.

"I did think of something!" Li Mu said: "Fengyulou acted secretively and ruthlessly, but he still showed clues, abandoned the thinking of details, and gained insight from the overall situation, in fact, the owner behind the scenes of Fengyulou is clear." From the ledger, as well as the identity of Zheng Tuhu, you can guess one or two. ”

"We're in trouble......"

Saying that, he left, returned to the county office, and notified a catcher, asking him to inform the six doors of Ningbo Mansion to catch heads.

The wind and rain building has already involved the rivers and lakes, and it needs six doors, or the Xuanjing Division has come forward.

Catch and leave.

Li Mu fell into anxiety.

In the blink of an eye, it's night.

Whew!

Suddenly the wind sounded, the candle was blown out, and in the moonlight, a man in black appeared.

"Who are you?"

Li Mu asked.

"The Killer of the Wind and Rain Building, Blood Red!" The man in black said, "You shouldn't be involved in the affairs of the Wind and Rain Building, since you have read the account book, you can't keep you, you should die!"

As he spoke, the man in black pulled out his sword, and suddenly a silver light slashed across the moonlight.
