"Oil and coal ink, Yuan Bao Zhang?" Zhang Han muttered to himself.

The crown prince Liu Yu asked directly: "What is this?" ”

"These are the raw materials for the imperial court to rub silver tickets, and every little bit used must be recorded in the book."

"So, they're the next evidence we're looking for!"

Li Changkong's eyes were shining, and he told the plan in his heart: "Zhong Jian only found that the strokes were wrong on the counterfeit banknotes, but the rest of the money was not flawed at all. ”

"But I learned that if you want to print a silver ticket, you don't just have to have a rubbing. Two very critical raw materials are also needed! ”

"Among them, oil and coal ink is a special ink used to rub the color patterns on the silver ticket, which is only produced in Xishan Mansion in Jizhou, and the annual output is extremely rare, and it must be handed over to the imperial court as a tribute!"

"After the rubbing is completed, it will be stamped by the Treasure Banknote Bureau with a unique ingot seal, so that the silver ticket can be considered effective and can be officially sold."

"Otherwise, if these two items are missing, the real money will also become a counterfeit."

"And Zhong Prison, as a veteran of the Criminal Department for decades, only discovered the problem of rubbing, which means that the oil and coal ink and Yuan Baozhang are real!"

"But these two items are extremely important materials, and every time they are used, they must be recorded."

"So, now Your Highness, you and Lao Zhang, one goes to the Ink Bureau, and the other goes to the Treasure Money Bureau, and looks through their case vaults in the name of investigating the case."

"As long as you can find a record of the abuse of oil and coal ink and ingots, it is solid evidence!"

"When the time comes, it must not be difficult to find out the connection between the officials of the two bureaus and Liu Jing."

After listening to Li Changkong's overall plan, Zhang Han and Liu Yu glanced at each other, both relieved.

Obviously, the two of them once again have a backbone in their hearts.

Li Changkong in this state is the familiar Li Changkong in their memory.

"Without further ado, let's wait until dawn to act?" Zhang Han asked.

Liu Yu nodded: "Okay, if the evidence is implemented this time, Liu Jing is afraid that he will be completely ruined!" ”

Li Changkong also nodded, no matter how much Emperor Jing Xing loved Liu Jing.

When it comes to such a major event of people's livelihood, it will never be spared!

It is light to be reduced to a commoner, and what is even more terrible is life imprisonment, or even... Direct decapitation!

……

The next morning, early in the morning.

Zhang Han finished washing, didn't tell anyone, only took a coachman, sat in a carriage, and went straight to the ink bureau!

It is difficult to say whether there are traitors among them or not, and who the traitors are.

But it's always right to be on guard.

A moment later, the ink bureau was about to arrive, but the street outside the carriage suddenly became noisy.

Zhang Han frowned slightly, and asked the coachman, "What's wrong?" ”

"Back to the young master, it seems to be out of the water."

Zhang Han nodded, it is the height of summer now, the weather is hot, and it is not uncommon to walk in the water.

However, out of curiosity, he still asked more: "Where is the water?" ”

"It seems to be the ink bureau, and the officials inside ran out in disgrace and said that the ink was on fire."

Groov!

Zhang Han's heart contracted instantly, and the whole person stood up rubbingly, no longer paying attention to the coachman, but quickly walked out of the carriage.

Sure enough, all I saw was the shouts of walking water.

Not far away, in the Ink Bureau, there are a few grizzled officials who are complaining.

What's more, they took the basin and rushed into it.

"There can't be such a coincidence in the world!" Zhang Han muttered.

Then he yelled: "It's water!" Come and put out the fire! ”

"Hurry up and put out the fire!"

"When the fire is extinguished, five taels of silver per person, I am the prince of the Dingguo Mansion, and my words count!"

Zhang Han directly sacrificed the moves of Li Changkong and Chen Qianyuan when they were fighting.

Although this trick is full of copper smell, it can't stand its use!

As soon as they heard this, many passers-by who were still watching the excitement immediately took the water and rushed in.

After tossing and turning like this for half an hour, the fire was finally extinguished.

A middle-aged man with a black and gray face and a bloated figure walked over to Zhang Han, bowed deeply, and hugged his fists and said, "Thank you, Shizi!" ”

"If it weren't for you today, I don't know when this fire would stop."

Zhang Han ignored these, but went straight to the point: "Where is the fire, but the case room?" ”

When the man heard this, he was immediately dumbfounded: "Zhang Shizi is not a god?" It's the fire in the case room! ”

"At that time, Director Hao was in it to check the case, and somehow, a fire suddenly broke out."

"If we hadn't rescued him in time, I'm afraid Director Hao would have burned half his life."

Hearing this, Zhang Han let out a long sigh, feeling sincerely tired, and said helplessly: "Can I go into the case room to take a look?" ”

The man was a little surprised when he heard this, but he nodded anyway.

After all, he is the prince of Dingguo, with a noble status, and he just spent a lot of money to help put out the fire, and he just wanted to enter the case library to take a look.

After a while, Zhang Han walked out of the case room, his face was extremely pale.

He guessed correctly, the records of the use of oil and coal ink in the past year have been burned clean!

Even, the storage place of those materials is the core ignition point!

This fire did not happen by accident at all, but someone deliberately set it on fire!

But at that time, there was only one Hao Chang in the case room, and now he was burned unconscious.

Even if he wanted to ask, he would have to wait for Hao Chang to wake up before asking.

"Damn! Got a head start again! I hope His Royal Highness the Crown Prince will have a smoother time there! Zhang Han said.

But there was a faint worry in his heart, the other party even thought of the oil and coal ink, how could he miss the ingot chapter?

At this moment, Liu Yu has just arrived at the Treasure Banknote Bureau.

He deliberately didn't bring Wei Xiang, not even half of his servants, and came alone!

It's just that as soon as I entered the treasure banknote bureau, I was stopped by the person in front of me.

I saw that this man was about forty or fifty years old, with a thin body, with a straight face, and was looking at him with squinted eyes.

"You are Luan Fu, the director of the treasure banknote bureau?"

"Exactly, I don't know what to do?" Luan Fupi smiled and didn't smile.

"This palace is the crown prince, and by the will of His Majesty, the counterfeit money case will be thoroughly investigated."

"Now I suspect that your treasure money bureau is related to this case, and this palace wants to check the use records of the ingot treasure chapter!" Liu Yu said sharply.

When Luan Fu heard this, he didn't raise his eyelids, but said disdainfully: "You said you are the prince, you are the prince?" ”

"I'm still the king of heaven! Tokens out! ”

"Tokens? What token? Liu Yu was surprised.

"The Treasure Money Bureau is an important place for the imperial court, and the case room is an important place for the Treasure Money Bureau, which can be described as a completely confidential place."

"You can enter a place like this, you can go in if you want? Naturally, it is a token that needs to be presented by the household. ”

"Presumptuous! This palace has been ordered by His Majesty to come to investigate the case, how dare you stop it? ”

"Or do you say that your treasure money bureau only respects the household department, not the holy frame?" Liu Yu was completely angry and scolded loudly.
