"My in-laws are not outsiders." Old Madam Zeng did not show weakness at all.

Mrs. Zeng really loved and respected her wife, so she glared at her and didn't continue to say anything, but said to Jiang Wanbai: "See me." ”

Jiang Wanbai shook her head, indicating that she was a little disturbed.

After a polite look, everyone returned to the living room. At this time, Mrs. Zeng showed Mrs. Zeng the bracelet that Jiang Wanbai gave her, and Mrs. Zeng was also full of surprise, for the first time, seriously, looked Jiang Wanbai up and down.

In his impression, Jiang Wanbai was an ordinary peasant woman, but he didn't expect her to take out the clams and give them to his wife so lightly. In addition, she had already heard about some things about her and the Tang family, and Mrs. Zeng became more and more aware that Jiang Wanbai was really a little unusual.

Perhaps, marrying the Tian family is not as bad as he imagined.

Mrs. Zeng looked at Jiang Wanbai, Jiang Wanbai was also looking at him, and Zeng Jingwen. As she thought, Mrs. Zeng was an upright person at first glance, and as for Zeng Jingwen, his quiet appearance was not like a nerd who only knew how to read.

In this case, there is one thing in her heart that she can say.

"Zeng Gongzi just said that you are going to do business, I don't know what business you want to do?"

"In-laws, what is the name of Zeng Gongzi, just like me, just call him Jingwen." Old Madam Zeng interjected.

Zeng Jingwen nodded hurriedly, "What my mother said is, just call me Jingwen." As for what kind of business to do, I think about it, and I feel that I have lived for so many years, and it seems that I am not very good at anything other than reading a little more.

So, I wondered if I could open a bookstore or a shop specializing in antiques, calligraphy and paintings. ”

His answer was basically not Jiang Wanbai's expectation, "Is it open in Yancheng?" ”

Zeng Jingwen nodded.

"I'm afraid it's not easy. This Yancheng is a small city by the sea, and the total number of scholars in the city is less than thousand, including some people who can't afford to buy books at all.

As for antique calligraphy and painting, I'm afraid it's even less optimistic. In my opinion, if you can go to the capital to open it, with the influence of the Zeng family, whether it is a bookstore or an antique calligraphy and painting shop, you will definitely be able to make a profit, but it will be ...... here."

Zeng Jingwen didn't know what Jiang Wanbai said. But with the current situation of the Zeng family, it is impossible for his father to agree to him returning to the capital.

"If you don't open a bookstore......" Zeng Jingwen was a little at a loss.

"I have a business here, but I don't know if you're interested?"

"Oh?"

"Do you know about Ghost Rock Beach?" Jiang Wanbai suddenly asked a seemingly useless word.

Zeng Jingwen was born in Yancheng, and often went to the beach to play when he was a child, of course he knew about this ghost rocky beach, but he didn't know what Jiang Wanbai's words meant.

Old Madam Zeng was a good-tempered person, and immediately urged: "My family, I also know about this ghost rocky beach." Don't go around or spin around, if you have anything to say, just say it. ”

Jiang Wanbai no longer sold Guanzi, and said that the ghost rock beach was actually formed by oil leakage, what is the use of oil, what are the characteristics, and why those supernatural things appeared in the ghost rock beach before, and completely explained it again.

Finally, he said: "The business I am talking about is related to this oil. ”

In ancient times, before the invention of the gas engine, oil actually had several main uses. One is to directly light the lighting, in which oil can be made into stone candles. Such a stone candle can hold three candles at a time, which can be described as cheap.

However, if it is used for lighting, one of the disadvantages is that the oil burns to produce black smoke. Over time, the house and bed tent will be blackened, so it is generally only used by poor families in order to save money.

But fortunately, this oil is an ownerless thing, and if you really want to sell it, it is like a business without capital, and the profit is also considerable.

Of course, this is just the simplest, and it is also the method that Jiang Wanbai disapproves of the most. Because oil produces black smoke from combustion, it has a second use, that is, to make ink.

Shen Kuo's "Mengxi Bi Tan" records that the ink made from oil is lighter, darker, and of better quality than that made of pine. It's just that because of the low oil production, it has not been developed.

If the Zeng family can develop this kind of ink, with the Zeng family's status in the academic world, the ink will definitely become famous, and at that time, the grand scene of a thousand gold and ink will not appear. Even, the Zeng family is likely to be passed down through the ages because of this ink.

This belongs to the high-quality route, which is what Jiang Wanbai admires the most.

In addition, oil can also play a lubricating role. For example, the axle will turn more lightly if it is smeared with some oil.

Of course, the stone can also be used for warfare. Just imagine, a lit oil barrel is equivalent to a dynamite package. In this ancient world, which was full of cold weapons, this oil barrel was no less powerful than a nuclear bomb.

Jiang Wanbai didn't tell the Zeng family about this application, she was afraid that it would cause the court's attention. When the time comes, not only will I not be able to make money, but I am afraid that the destruction of the family and the clan will be imminent.

But just these three applications, the Zeng family was also dumbfounded. They didn't expect that the place known as Ghost Rock Beach would hide such a treasure, which was simply a vault.

"What you said is true?" At this time, even Mrs. Zeng couldn't sit still.

"Of course."

"It's true, it's true...... Although the old lady Zeng is concentrating on learning, but after living for so many years, he still has the knowledge he should have, so he immediately realized what a good opportunity this is, and couldn't help but stand up, put his hands behind his back, and walked in the living room.

Zeng Jingwen was already excited and didn't know what to do, he had already seen his future path, saw the hope of the Zeng family's future, and now he couldn't wait to immediately put on his wings and fly to the ghost rock beach.

Even Mrs. Zeng was stupid, she thought that Jiang Wanbai was talking about some kind of business, but she didn't expect it to be such a great opportunity.

Jiang Wanbai looked at the three of them, and sighed a little in her heart. They only know a little bit of what oil is used for, and if they know the real purpose of oil to make you fly and make you run, they don't know what it would be like to be surprised.

It's a pity that there is no steam engine now, otherwise, she would have been able to carry out an industrial revolution in this ancient world. No, this steam engine is not completely impossible...... Jiang Wanbai suddenly thought of a person, if he was invited to study together, this oil should be able to develop more uses.

The more she thought about it, the more perfect she felt, and Jiang Wanbai became excited.

"That thing called oil, is the ink really as good as you say?" Mrs. Zeng still pays more attention to reputation, so she cares more about this.

"Indeed." Jiang Wanbai patted her chest and promised.

"How do you know that?" Old Lady Zeng had calmed down a little at this time and began to think about some questions.

This ...... "I'm from the future?" I'm afraid that if I dare to say it, you won't dare to believe it, Jiang Wanbai was a little speechless for a while.

"Father." Zeng Jingwen shouted, he can't wait to offer Jiang Wanbai like a bodhisattva now, he is really a little afraid of annoying her.

Old Lady Zeng did not retreat at all, and looked at Jiang Wanbai with burning eyes.

Jiang Wanbai's mind turned, and she took out the person she thought of before, "Old lady Zeng knows about Scholar Lin?" ”

In the current dynasty, there was only one person who could be called a Lin student student, and the old lady Zeng didn't know how to do it, "You are talking about the owner of the You Hong Poetry Society, Lin Qiyuan, who just published "The Theory of Heaven and Man" last year. ”

"Yes, that's him." Master Lin is not only a literati, but also a scientist, last year, he also intersected with Jiang Wanbai because of buoyancy and small hole imaging, and also helped Jiang Wanbai, so Jiang Wanbai wanted to pull him over to study the real use of oil.

Now, he's also the best shield.

Sure enough, when it came to Bachelor Lin, Mrs. Zeng, who was full of poetry and books, also felt inferior, "It's him, it's him, no wonder." I said, if there is really one person in this world who can know such wonderful things, there is no one else but him. Hahahaha. Old lady Zeng actually laughed.

Zeng Jingwen also sighed, "It's a pity that he left the government and the opposition early, and I didn't have the opportunity to meet him, which is really a regret in my life." ”

"Maybe you're going to see him soon." Jiang Wanbai smiled slightly.

"Oh?" Zeng Jingwen was a little puzzled.

"There's more to this oil than that. Also, about its mining, refining and other things, I think I have to come to Master Lin himself.

So, I have a mention yì. If you think this business is feasible, we will call Master Lin and the three of them will partner in this business, how about it? Jiang Wanbai finally said her plan.

"Of course it's good that Master Lin can come, but I'm afraid that he won't come......" Zeng Jingwen was a little eager to speak.

"He's coming." Jiang Wanbai is still very confident in this. Think about it, a science madman, if you tell him about these wonderful things here, it will be strange if he doesn't come.

Zeng Jingwen saw that Jiang Wanbai was so confident, and immediately thought that their relationship must be unusual, and immediately smiled reassuringly, "That's good." ”

"Old lady Zeng, what do you think?" Old Lady Zeng is the master of the three princes, and Jiang Wanbai still wants to drag him into the water together.

Old lady Zeng twisted her beard, looked at Zeng Jingwen who was excited, groaned, and suddenly said, "That ink is made, I want to test it myself." If it's really good, you can sell it. ”

He just agreed, Jiang Wanbai immediately nodded in agreement, and said with a smile: "That's natural." When the time comes, I will ask the old lady to give this new ink a nice name. ”

This kind of thing to leave a name, Mrs. Zeng naturally couldn't ask for it, and there were more and more smiles on her face, and even the wrinkles were stretched out a lot in the end.

"Humph! It's cheap and good. Old Madam Zeng glanced at Old Madam Zeng and mocked with a smile on her face.

Mrs. Zeng was a little embarrassed, but she had no choice but to stare at Mrs. Zeng.

"What are you staring at, am I not right? At that time, you didn't agree to this marriage for Cheng'er, but now what? Old Madam Zeng took advantage of the reason, and she was quite proud of it.

"Only villains and women are difficult to raise." Old Mrs. Zeng shook her head and sighed, but there was no anger between his eyebrows, it was all about the old lady Zeng's love, which showed how good the relationship between the two was.
