"Oil coal ink, ingot seal?" Zhang Han muttered to himself.
Prince Liu Yu asked directly: "What is this?"
"These are the raw materials used by the imperial court to print banknotes. Every time a bit is used, it must be recorded in the book."
"So, they are also the evidence we are looking for next!"
Li Changkong's eyes sparkled, and he explained the plan in his mind: "Zhong Yu only found errors in the brushstrokes on the counterfeit banknotes, but there were no flaws in the rest."
"But I learned that if you want to make rubbings of banknotes, it's not just the rubbings that are enough. You also need two very critical raw materials!"
"Among them, oil ink is a special ink used to imprint the colorful patterns on silver notes. It is only produced in Xishan Prefecture in Jizhou. The annual output is extremely rare, and it must be handed over to the court as a tribute!"
"After the rubbing is completed, the banknote bureau will stamp it with a unique ingot seal, so that the banknote will be considered valid and can be officially sold."
"Otherwise, if these two items are missing, the real banknotes may become counterfeit."
"As for Zhong Yu, who has been a veteran of the Ministry of Justice for decades, he only discovered the problem with the rubbings, which means that both the oil ink and the ingot seal are real!"
"But these two items are extremely important materials. Every time they are used, they must be recorded in the book."
"So, now, Your Highness, you and Lao Zhang, one will go to the Ink Bureau and the other to the Treasure Bank Bureau, to look through their case files in the name of investigating the case."
"As long as we can find records of the abuse of oil ink and ingot seals, it will be solid evidence!"
"It won't be difficult to follow the clues and 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 looked at each other, feeling relieved.
Obviously, the two of them have a backbone in their hearts again.
Li Changkong in this state is the familiar Li Changkong in their memories.
"Without further delay, let's take action as soon as daybreak?" Zhang Han asked.
Liu Yu nodded: "Okay, if the evidence this time is implemented, Liu Jing will be completely ruined!"
Li Changkong also nodded, no matter how much Emperor Jing Xing liked Liu Jing.
When it comes to such important matters of people's livelihood, we will never be lenient!
Being demoted to a commoner is a light thing, but what is even more terrifying is being imprisoned for life, or even...direct beheading!
…
The next morning, early in the morning.
Zhang Han finished washing up and without telling anyone, he only took a coachman with him and rode the carriage straight to the ink bureau!
Whether there is a traitor among them or who the traitor is is hard to say.
But it’s always right to be careful.
A moment later, as the ink station was about to arrive, the street outside the carriage suddenly became noisy.
Zhang Han frowned slightly and asked the driver: "What's wrong?"
"Come back to me, young master, it seems that you have lost your temper."
Zhang Han nodded, it was midsummer now, the weather was hot, and it was not unusual to get into the water.
However, out of curiosity, he asked one more question: "Where did the water leak out?"
"It seemed like it was the printing and ink bureau. The official inside ran out in disgrace and said that the ink was on fire."
Ding!
Zhang Han's heart suddenly contracted and he stood up. He ignored the coachman and quickly walked out of the carriage.
Sure enough, all that came into view were the shouts of people walking through the water.
In the printing and ink bureau not far away, there were a few disgraced officials complaining incessantly.
What's more, they take a basin of water and rush it in.
"There can't be such a coincidence in the world!" Zhang Han murmured.
Then he yelled: "The water has escaped! Come and put out the fire!"
"Come quickly to put out the fire!"
"When the fire is out, I will give you five taels of silver per person. I am the heir apparent of Duke Dingguo. I will keep my word!"
Zhang Han directly used the moves used by Li Changkong and Chen Qianyuan during the fight.
Although this trick is full of the smell of copper, it is so useful!
Upon hearing this, many passers-by who were still watching the excitement immediately took water and rushed inside.
After struggling like this for half an hour, the fire was finally extinguished.
A middle-aged man with a gray face and a bloated figure walked towards Zhang Han, bowed deeply, cupped his fists and said, "Thank you, Your Majesty!"
"If it hadn't been for you today, I don't know when the fire would have stopped."
Zhang Han ignored all this and said straight to the point: "Where did the fire start? Is it the desk room?"
When the man heard this, he was immediately dumbfounded: "Could it be that Prince Zhang is a god? It was the fire that started in the filing room!"
"At that time, Director Hao was checking the documents, and for some reason, a fire suddenly broke out."
"Had we not rescued him in time, Director Hao would have been burned for half his life."
After hearing this, Zhang Han let out a long sigh, feeling sincerely tired, and said helplessly: "Can I go into the filing room and take a look?"
The man was a little surprised when he heard this, but he still nodded.
After all, he is the prince of Dingguo and has a noble status. Moreover, he just spent a lot of money to help put out the fire. I just want to go into the archives and take a look. Although it is not in line with the rules, there are always exceptions to everything. People cannot live too anciently.
plate.
After a while, Zhang Han walked out of the desk room, his expression extremely ugly.
His guess was correct. All the oil and coal ink usage records in the past year have been burned clean!
Even the storage location of those data is the core fire 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 desk room, and now he was burned to the point of unconsciousness.
Even if he wanted to ask, he would have to wait until Hao Chang woke up before asking.
"Damn it! I got one step ahead again! I hope things go smoothly for His Highness the Prince!" Zhang Han said.
But there was a faint worry in my heart. The other party had even thought of oil, coal and ink, so how could he miss the ingot seal?
At this moment, Liu Yu had just arrived at Baochao Bureau.
He purposely didn't bring Wei Xiang with him, not even half of his servants, so he came alone!
However, as soon as he entered the treasure bank, he was stopped by the person in front of him.
I saw that this man was about forty or fifty years old, thin in stature, with a straight face, and he was looking askance at him.
"Are you Luan Fu, the director of the Baochao Bureau?"
"Exactly, I don't know what you are doing?" Luan Fu said with a smile.
"I am the prince, and according to His Majesty's decree, I will thoroughly investigate the counterfeit currency case."
"Now that it is suspected that your Baochao Bureau is related to this case, I want to check the usage records of the Yuanbao Chapter!" Liu Yu said sternly.
When Luan Fu heard this, he didn't even raise his eyelids. He just said disdainfully: "You said you are the prince, but you are the prince?"
"I am still the King of Heaven! Take out the token!"
"Token? What token?" Liu Yu asked in surprise.
"The Baochao Bureau is an important place for the imperial court, and the Document Room is also an important place for the Baochao Bureau. It can be said to be a completely secret place."
"You can enter a place like this if you want? Naturally, you need a token from the Ministry of Household Affairs."
"How dare you! I have been ordered by His Majesty to investigate the case. How dare you stop me?"
"Or are you saying that your Baocha Bureau only respects the household department and not the holy frame?" Liu Yu was completely angry and yelled loudly.
