"Your son-in-law, once had a relationship?"

After listening to Yanqiu's words, Cheng Yujiao couldn't help asking. When she opened her mouth, she regretted it, and it was very inappropriate for a woman in this era to ask a man about his feelings.

Sounds good, are you interested in this man? To put it mildly, are you spring?

Before getting married, the woman's expression was very subtle, and this was very direct, but Li Erniang didn't notice this, but replied seriously.

"My son-in-law is good at everything, but he doesn't have a woman's popularity."

Cheng Yujiao didn't believe it, although Jiang Wei looked average, he was better in temperament. Men don't need to be too handsome, in the eyes of women with connotations, too handsome is flashy and unreal. Only true talents and real learning, with an average appearance, such a man, wherever he goes, there will be women who are not loved, let alone Jiang Wei?

I don't know what Cheng Yuzhen thought, she opened her mouth in surprise, and there was a sentence that she almost burst out.

Does your son-in-law like men?

Fortunately, Cheng Yujiao's self-control is good, and she has never been able to say this sentence, but a flush of excitement appeared on her face inexplicably.

At this time, Jiang Wei and Cheng Chuliang had just finished talking, and they sneezed inexplicably, rubbed their noses and didn't care too much.

This time, Cheng Chuliang brought a lot of information.

The owner of the teahouse is the contact person responsible for communicating with Chen Shuozhen and planning. After Chen Shuozhen lost his freedom, he has been sending people to monitor Jiang Wei's every move, and as long as there is an opportunity, he will carry out a second hijacking again.

After Jiang Wei listened, he couldn't help but his eyelids jumped. He gritted his teeth. At this moment, he felt a feeling of contempt. It's as if they have become meat on the chopping board, whether they want to stew, fry or steam, as if they have become something that they can decide with one sentence.

At first, Jiang Wei was a little hesitant, after all, this matter was too big. He felt a little out of breath from the pressure.

But at this time, Jiang Wei no longer hesitated, he smiled lightly and spit out a breath of turbidity,

"Chu Liang, one more thing to help the teacher."

Cheng Chuliang nodded with a serious face,

"Master, you just command."

Jiang Wei groaned and thought about it seriously,

"I want you to catch all these people. Leave only one living mouth to contact the upper family, I am useful, go. ”

After Cheng Chuliang left, he went to the living room under the guidance of the maid. As soon as I entered the living room, I saw Cheng Yujiao, who was in her soul, and felt very strange for a while.

"Little sister, what's wrong with you?"

Cheng Yujiao saw that it was her second brother, so she came back to her senses,

"It's okay, second brother, are you done talking to Jiang Gongzi?"

Cheng Chuliang glanced at this sister suspiciously, he rarely saw Cheng Yuzhen's appearance, what did he encounter in Jiang Mansion? But thinking of the task given to him by the master, it was more urgent, and he didn't ask.

"Let's go back first,"

Cheng Yujiao was not very happy, there were too many questions she wanted to ask this time.

"I still have a lot of things to ask Jiang Gongzi, what about Jiang Gongzi and others? Why don't you see him come out? ”

Cheng Chuliang said helplessly,

"The master has something, how can he have time to take care of you?"

Cheng Yujiao held her mouth, but she was not a person who was messing around, and she had gained a lot today, so she followed Cheng Chuliang back to Cheng's mansion.

As soon as he returned to Chengfu, a guard came to report that Princess Qinghe was coming.

Cheng Chuliang had something to do, so he left in a hurry and asked her to say hello for herself. Where does Cheng Yujiao care about this, as soon as she heard that Princess Qinghe was coming, she immediately became excited, and decided to tell Princess Qinghe the good news of today's harvest.

Princess Qinghe's full name is Li Jing, and she can be said to be a rare good princess. She is a virtuous woman and is the concubine of His Majesty Li Er.

Although she is not a virtuous lady, compared to her sisters, such as Princess Gaoyang, who is the first in trouble, gave Fang Er a Hulunbuir prairie, a waist slashing experience card to the debate monk, and a family destruction experience package to Fang Xuanling's family.

Among the daughters of His Majesty Li Er, there are not only Princess Gaoyang, but also several. For example, Princess Chengyang, the daughter of Empress Changsun, gave Xue Juma an experience card for guest death.

Princess Baling and Chai Lingwu experienced a one-way travel ticket to the Netherworld. Princess Dongyang was with her husband and received a one-stop service of seizing the city and being exiled.

Compared with these princesses, Princess Qinghe in history kept to herself. Princess Qinghe did not give Cheng Chuliang a forgiveness hat experience card, nor did she give the Cheng family a package for the destruction of the family. Among the daughters of His Majesty Li Er, Li Dexian can be regarded as a good wife.

At this time, Princess Qinghe was waiting in Cheng Yujiao's boudoir, and not long after, she saw Cheng Yujiao trotting in with great interest.

"Princess, I've discovered a big secret."

When Princess Qinghe saw her like this, she was quite curious for a while,

"What's the secret?"

Cheng Yujiao looked out of the door, and then closed the doors and windows with her backhand. Princess Qinghe saw it.

Princess Qinghe sat in front of the dresser, and Cheng Yujiao stood beside her, helping her comb her hair while looking at Princess Qinghe with a rosy face in the mirror.

"Princess, you are so beautiful."

Princess Qinghe smiled sweetly,

"You haven't told me what the secret is!"

Cheng Yujiao whispered in her ear at this time,

When Princess Qinghe heard this, her eyes widened in surprise for a while, and she couldn't believe it,

"You mean Jiang Gongzi ...... him?"

After finishing speaking, Princess Qinghe's face also flushed with excitement.

This afternoon, the two girls had a discussion called curiosity about the total possibility.

In Jiang's Mansion in Yunling Village, Jiang Wei didn't know anything about the discussion of the second daughter, so he went into the laboratory and prepared to start the production of gelatin.

Photographic gelatin is one of the three important materials in the production of photosensitive materials, and due to its unique physical and chemical properties, there is no substance that can completely replace gelatin.

The raw material used in photographic gelatin is fresh beef bones. Collagen purification adopts the liming method, the time is as long as 90~100 days, and it is the first product obtained by extracting with hot water in the first extraction temperature of 40~50 °C.

As a result, photographic gelatin is the product with the highest purity, the fewest impurities, the greatest gel strength, the lightest color and the highest transparency.

However, with the current conditions, Jiang Wei is temporarily unable to achieve the second purification, and the effect may be much worse than that of gelatin in the previous life.

During this time, Jiang Wei did not let Li De be idle, but asked him to collect fresh beef bones. After these days of hard work, I finally found a batch of fresh beef bones in the morning, and then decided to start making gelatin in the afternoon.

After obtaining gelatin, it is only one step away from film molding, and only photosensitive material is left, and the film production can begin.
