Chapter 936 (1/2)

Through careful analysis of the agent Younai, lingshang knows that there are not a few of the Donghuang Wuji lackeys who have been mixed into the Sanjie Public Security Bureau.

The internal ghosts of the Intelligence Department of the general administration can be locked in, while those hidden in other departments are still unknown. The enemy is in the dark and they are in the light. The situation is very serious.

Gong Youen recognized the woman's photo sent by Bai feiran and identified that the person in the photo, Quan Ji, was Quan Miao's sister and a very popular woman under the throne of emperor Wuji.

But this does not prove that Quan Ji is the woman who sent this letter anonymously.

Soon, however, Gong Youen, who had studied anatomy and trace identification at Harvard Medical School, found clues on the envelopes and papers of anonymous letters.

”My cousin, this paper is a very high-grade retro parchment with a strange fragrance on it. It is specially customized. From the production to the sale, this paper is privately made, which is not available in China. It is a British craft.”

Gong Youen, wearing white gloves and using the golden magnifying glass of lingshang's office, was observing the letter carefully. As he spoke, he suddenly pointed to the edge of the lower left corner of the letter.

”There is a circle of reddish marks in the lower left corner.”

”It doesn't look like the pattern of a letter paper. It looks like it's dirty.”

Ji you is close, suspecting the way.

”Do you have lye, please?” Gong Youen suddenly looks at lingshang.

Purple eyes slightly a blink, Ling Shang soft look to Ji You Nai, ”elder sister, what is alkaline water?”

“…… A kind of alkaline water, you go to ask the scientific research department of the General Administration of China. There must be some. It's better to have another dropper. ”

Jiyunai knows what Gong Youen wants to do. He wants to test the reddish mark on the paper with alkaline water.

Lingshang soon ordered people to send the things Gong Eun needed.

Then, Gong Youen took a few drops of lye with a dropper, and slowly dropped it on the red mark on the lower left corner of the writing paper.

As soon as the alkaline water soaked the pink mark on the writing paper, it slowly showed a light blue state.

”This is dry red wine stains, grape skin red in acid conditions will be red, purple red, alkaline will become dark blue.” With that, Eugene picked up the writing paper again and sniffed it. The fragrance attached to the parchment and the residual fragrance of the wine after the red wine dried up quickly made Gong Youen identify the variety of the wine, as well as the brewing time and grade.

”This wine should be brewed within ten years. It belongs to high-grade red wine, but it is not of taste and collection level. It should be Cabernet dry red. This wine will not be used in foreign high-end Western restaurants, nor will it be collected by people who understand wine. But it is a relatively expensive red wine in the market. It is often provided in five-star hotels and nightclubs. To put it more simply, this wine is It's for people who don't know how to drink. ” Gong Youen, a blonde and blue eyed girl, has a good idea and then goes on to say, ”Quan Ji is a very elegant and extravagant woman. She has to customize a piece of writing paper. Therefore, she will not easily drink this kind of wine which reduces her taste, unless...”

”Unless the wine was provided by her place, and she was in a good mood when she wrote this anonymous letter and wanted to drink to celebrate? Of course, it's just speculation. There's no evidence. ” Jiyou is the connecting cavity.

”Let's look at the envelope again.”

The envelope was white and ordinary, sealed with red lacquer and marked with a rose. It was like a person who went out in a hurry and brought exquisite custom-made parchment without using the same very high-grade envelope.

This gives Ji you a sense of disobedience.

The letter paper is so expensive, but the envelope is so rough?

”The woman who wrote this letter is very intelligent. She has a strong sense of anti reconnaissance. She knows that customized things are easy to trace to the source, but she doesn't want to lower her taste. So she likes to customize parchment, but the envelope only uses very common material. She is very careful. This envelope has been cut and printed in the lower left corner She did some writing, and she took care of it. ”
