Jun Qinglan hooked the corners of her lips slightly, and when she saw the look in Fang Qing's eyes, she knew that Fang Qing had already seen the mystery in the drawing.

"Fang Zhutou, what do you think?"

Jun Qinglan took half a step back and handed over the initiative to Fang Qing. In the end, she is an outsider, and she is a character closely related to this case, Huang Zhong is afraid that he has long disliked her to the extreme. Fang Qing was different, he was originally Huang Zhong's very trusted subordinate, so if the two of them said the same thing, it would cause different results.

"There's something wrong with this drawing." Fang Qing didn't shirk, took Jun Qinglan's words, and raised his hand himself, pointing towards the thin ink line.

"Your Excellency, please see, when the light comes out from behind the paper, it is brighter here than it is elsewhere. Although the difference is very subtle, it can be seen on a closer look. ”

Fang Qing's voice paused for a moment, and only then did he continue after making sure everyone saw it.

However, since the paper used to draw the drawings came from the same source and stored in the same environment, there was only one reason for this, and it was tampered with at some point later. This is the first inadequacy. ”

Everyone frowned when they heard this, the first is inappropriate? Could it be that there is still a second or third that can't be done?

As soon as this thought came to mind, I heard Fang Qing really say a second.

"Second, where the paper is thinned, there are some irregular fine folds on the surface of the paper, but elsewhere the paper is smooth, and there is no such phenomenon. Thirdly, it is this ink line, which looks a little darker than elsewhere. ”

Jiang Yu Fanqi said: "The ink is black, can it also become an unreasonable place?" ”

"Normally not, but it's a big mistake to put it here." Fang Qing said: "All the state capitals of Northern Xia have pen and ink production, but the color of the font written by the pen and ink sold by each firm will be more or less different. Even the pen and ink produced by the same firm will reflect subtle differences due to the difference in the environment and temperature at the time of production. Even if it is produced in the same batch, it will show different color effects due to the different strength and habits of the writer. ”

Jiang Yufan scratched his head: "In a small pen and ink, there is still so much knowledge hidden?" ”

Fang Qing turned around and returned his gaze to the drawing: "The lines of this drawing are uniform and full, and the ink is slightly yellowed and faded due to the long storage in the treasury. Only this thin line, but it is very clear, and it is clearly written with different pen and ink. But....... ”

Fang Qing frowned: "This punishment has obviously been deliberately changed. But I really can't figure out what method that person used to modify the drawings and do it so seamlessly? ”

If it weren't for Jun Qinglan's repeated insistence, if it weren't for the fact that the back hall was a little dim, she brought the oil lamp close to the drawing, who would have noticed the subtle differences in the drawing? Of course, this technique can be called seamless!

"It's not hard to change the existing ink, you just need to master one thing."

Jun Qing's blue eyes froze, but he glanced at Li Congyao first. Li Congyao also looked at her at that time. The four eyes looked at each other, and they all saw solemnity from the bottom of each other's eyes.

Jun Qinglan knew that Li Congyao wanted to go with her. Wasn't the chronicle on that page of the Qin family tree manipulated in the same way? In this eye, there is heaviness and relief

However, there are doubts, but more worries and regrets.

Li Congyao is worried about her?

Jun Qinglan closed her eyes and turned her head away. She is the calm and calm of Beixia, and there is really nothing to worry about!

"I heard that a few years ago, Huang Lao solved a strange case with a magical liquid, just because that liquid can erase any handwriting written by pen and ink in the world. But the so-called liquid, after all, there are some shortcomings that cannot be ignored. When it falls on the paper, it dries up and leaves some fine wrinkles. ”

Jun Qinglan's voice was low and cold, and every word was slow and sonorous.

"At present, the villain believes that the memory of the county keeper has indeed not deviated, and someone took advantage of the opportunity of the construction of the underground sewer to dig a secret passage that no one knows, and it leads directly to the underground of the bedroom of the old Huang family. The purpose is very simple, it is to create a comfortable living environment for the pond lice. With the growth of pond lice fish, Huang Lao will inevitably be disturbed night after night, and eventually die quietly because of sleepless nights and poor spirits. At that time, he opened the iron gate again and let the pond lice fish swim down the underground waterway into the Jialu River, and the case ended unconsciously. Where did I think that by mistake, the pond lice fish actually became a water monster, so that the true face was exposed step by step. ”

Jun Qinglan took a slow breath: "He saw that his deeds were lost, but he was not willing to leak them. So, on the one hand, he informed the Huang clan ancestral hall that Wen Niang had committed adultery, and on the other hand, he sneaked into the government office and modified the waterway drawings. In this way, with both prongs, no one will suspect him anymore. Pity...... He did a lot of calculations but never thought that Wen Niang actually killed the moon in such a way, and was solved by a dog, and until now, the person who has always been hiding behind the scenes, I am afraid that he will not be able to hide anymore. ”

Jiang Yufan frowned: "How come there is still a person behind the scenes?" How complicated is this case? ”

"It's not complicated, but it takes a little longer." Jun Qinglan said slowly.

This person has been laying out the underground waterways since six years before the construction of the underground waterway, and he wants to get rid of Huang Yuan without knowing it, which is ...... What a terrible mind and perseverance. In order to kill someone, is it so hard?

"The house in Xuanshuifang under the name of Wen Niang is worth a lot of money, and Huang Lao's income is simply not enough to pay for that expensive expense. Aren't you wondering how he could afford to buy that house?

"Maybe you can say that you secretly financed your lover at the beginning of the month, but I want to tell you that it must be impossible."

Jun Qing's blue eyes were cold, and he continued: "At the beginning of the month, I was limited by the law, and I can't leave my lowly status and be good in my life. Such a cruel truth can make anyone crazy. When a crazy person meets a suitor who is crazier than her, she may be able to find a little comfort in her heart. But how can she be willing when the only fanatical man suddenly retreats and throws himself into the arms of others, and the woman above her is nowhere better than her? ”

Jun Qinglan was stunned, and her clear eyes slowly swept over all the men present, and her eyes gradually deepened: "Dare to ask you, how can such a woman take out her own body and silver, buy a mansion for a negative person, and then marry the woman next to her?" ”

After a little thought in their hearts, everyone knew that there was indeed no such possibility. If they were to be replaced at the beginning of the month, they would definitely not do this kind of thing that would make their relatives and enemies happy.

Therefore, the silver taels of the Huang family's new house were neither obtained by Huang Lao Yulu, nor was it secretly funded at the beginning of the month. Then there is only one possibility left for the origin of such a large sum of silver, and that is to be funded by others. ”

Jun Qinglan raised her eyes slightly: "Wen Niang once told me that one day she undoubtedly heard a corner between Huang Lao and the beginning of the month, saying that she wanted to introduce an old man for Huang Lao, and the old man's help to Huang Lao back then was always remembered. Therefore, it can be basically concluded that the silver taels for the purchase of the new house have a great relationship with the old man in the mouth of the month. ”

Huang Zhong frowned: "Lan Qing, what you are talking about in circles is some irrelevant things. Please don't waste everyone's time! ”

"What the villain said is naturally closely related to this case." Jun Qinglan looked at Huang Zhong, her eyes were firm, her chest and back were straight, stubborn and strong.

"The drawings of the underground waterways were altered by a special potion that could erase the handwriting. More than ten years ago, Huang Lao used this potion to solve a strange case, and since then he has become famous all over the world. Before the Year of the Six Gases, someone proposed the idea of building an underground waterway to the Gunjo-sama, and you received your support. It took about three years for the construction of the waterway to complete. After that, someone used the waterway pipe network as a support and cover, and dug a secret passage, which went straight to the bottom of Huang Lao's bedroom. After nearly three or four years, Huang Lao died of exhaustion after being tortured by pond lice fish. When searching for the drawings of the underground waterways of that year, it was found that someone had changed the direction of the drawings with a potion. The piles are all connected by a clear line. That line is a word elimination potion, isn't it? ”

Everyone was silent, and their hearts were thinking about Jun Qinglan's inference. The word elimination potion is indeed the key in this case, but ...... How does this relate to the case from more than a decade ago?

"Everyone only knows that the word elimination potion is owned by Huang Lao, and when it is used properly, it has become his assistant who has benefited in his career. However, you don't know that this potion was not created by Huang Lao. ”

Jun Qinglan took a breath: "Wen Niang Fang has already said in court that the word elimination potion was first obtained by Uncle Jing by accident, and after careful research, the ratio of the prescription was determined. This prescription aroused Huang Lao's great interest, and the Jing family uncle did not hide his secrets, so he gave the prescription to Huang Lao. Soon after, this medicine made a great contribution in a case, and Huang Lao received a lot of rewards, however, no one mentioned Uncle Jing. Soon after, Uncle Jing drowned because the stone bridge collapsed while watching the dragon boat race. Wen Niang was determined that Huang Lao was ruthless in killing people in order to monopolize fame and fortune, so she sold herself to become a cook in the Huang Mansion. After that, everyone is clear. ”

Jun Qing's blue eyes froze: "The characters related to this case, Wen Niang, Huang Lao, Yue Yue, and Uncle Jing, the only thing that can connect them together is the word elimination potion, which naturally cannot become an ordinary thing." To say it's useless is to be worthless. But if it falls into the hands of someone with a heart, this is a priceless treasure. ”

Jun Qinglan closed her eyes. The husband is not guilty, but he is guilty. It is precisely because this thing is remembered by people with a heart that Huang Lao will be in a difficult situation, and many innocent people will be implicated. And the Qin family ...... Fear is the real key to today's case.

"Your Excellency." Jun Qinglan suddenly opened her eyes, and her eyes were clear: "Villain, there is a bold conjecture!" ”
