The doll is soft and delicate, and her skills are at the top of the 70 exam

The next day.

Jiang Mengmeng covered the quilt and met those jet-black eyes.

Ouch, Mengmeng is scared to death, Mengmeng is scared to death.

"Dad, what are you doing? Why are you staying by my bed, why don't you hurry down and have breakfast?" Jiang Mengmeng patted Jiang Aiguo's shoulder very caringly, "Dad, your kindness is so cute. Now, I will go down to eat by myself, you just need to obediently fill your stomach, don't wait for me!"

Jiang Aiguo gritted his teeth, "You have to wait for your leaky daughter to eat. Look, look, look at your father and my eyes. If you hadn't said yesterday that I had private money, your mother wouldn't have let me stay all night." Lying on the floor sleeping, you little liar, tell me where your private money is hidden? Hand it over quickly, or daddy, I will kill you."

Jiang Mengmeng yelled and jumped out of bed in fright, "Dad, won't you secretly get up in the middle of the night and then climb into bed after sleeping on the floor? What are you doing? Sleeping on the floor obediently, you are too Stupid, you can't blame Mengmeng for sleeping on the floor."

Jiang Aiguo became aggressive, "If you didn't say that I have private money, would your father and I still sleep on the floor?"

Jiang Mengmeng is distressed, and I really can't blame her for it. Last night, her father insisted on asking her grandparents about their little secrets. She promised to keep it a secret, so she definitely can't tell it.

So she can only make excuses.

Jiang Aiguo, a manly man, can make his daughter run away easily. He still has a purpose today, but he can't let her run away easily.

So he caught the screaming girl and threatened, "With your little treasury, I will reluctantly let you go, but you have to agree to one request from daddy."

Jiang Mengmeng blinked and nodded obediently, "Father, tell me first, and then I will decide whether to agree or not."

Jiang Aiguo: ...you nodded first, isn't the latter sentence all nonsense?

"Do you still remember the little books you told me about yesterday?" Jiang Aiguo asked.

Jiang Mengmeng's whole face was wrinkled, "Dad, I've already told you, I can't tell you about grandparents' account book."

Jiang Aiguo waved his hand, "I don't care about your grandma's little secret now. What I'm telling you now is that I have confirmed it with your grandma. I will keep accounts at home in the future, but okay, at home The only thing I have is a pencil, but the pencil uses water, and the hands get dirty if you are not careful, which is very unsightly. The main reason is that the pencil is not easy to carry around, and the sharp refill is easy to get hurt, so now you have What is a good way?"

Jiang Mengmeng froze for a moment, her mind began to think, then her eyes rolled, she shook off her father's hand, and ran into her experiment room with a thud.

She remembered that she used a pen to get a refill some time ago.

Because the laboratory is cleaned by the old man and the old lady. The glass inside is their treasure, and they have to look carefully. In order to prevent grandma from touching dangerous objects, Mengmeng puts many things in wooden cabinets inside.

So Mengmeng went directly into the room, then opened the cabinet directly, and took out a small plate inside.

Jiang Mengmeng picked up the plate and ran towards her father.

When he was using an electronic pen in the system a long time ago, Mengmeng felt that his pen was not easy to use. Even if she wrote very carefully, the pencil would still get black everywhere, making the page blurry. It's very unsightly. Mengmeng thinks that she is still very clean, so she is not used to it, and what bothers her most is that it is very inconvenient to carry a pen or a pencil.

Every time she goes out, she hangs a small bag. Well, it doesn’t matter, but the ink that needs to be brought is very inconvenient. There are many clothes that get ink on, and it is very, very difficult to wash. Complained several times, saying that there were small black spots on her clothes that could not be washed off.

In fact, these small black spots are really not caused by ink, some of them are caused by pencils.

So she used her brain to think, is there any way to make this ink easy to use, not to leak out, and to carry it with you. .

After thinking about it for a long time, she began to complain, if only there was something like the electronic pen in the system.

No, Dabao heard this and recommended the oil-based pen technology to her.

This technology is not difficult at all. To be precise, its technical content is very low, and it belongs to a relatively backward technology. When Mengmeng asked, Dabao generously called out the information for Mengmeng, so that she could still see the picture. .

Jiang Aiguo's eyes lit up when he saw the things on the tray, "This thing is good, but isn't the outside too fragile? Yours is made of glass, isn't it too thin? Your grandparents are used by rough people. If something written with such a thin pen is pinched hard, wouldn’t it be all over the body?”

Jiang Mengmeng blinked, "Then why don't you find something to wrap it up?"

Jiang Aiguo thought it was a good idea.

"Let me think about it, let me think about it." Jiang Aiguo frowned, "If you don't need wood, this kind of thing is in the middle of the pencil. Let's find a thicker wood and put it in. In the future, Mengmeng, you can put this glass again Make it thinner so we can put this in when we hollow out the middle of the pencil."

Jiang Mengmeng shook her head, "I can't, the time it takes is too short, if you keep changing it, it will be very troublesome."

Dabao suggested, "Actually, Mengmeng, you can use iron sheets entirely."

"Ironhide?"

Dabao opened the picture for her, and showed Mengmeng a variety of printed iron shells, "Although these pens have been completely eliminated in our place, this handmade pen is still very valuable for collection. If You already have plastic here, you can use plastic to replace this iron sheet, but plastic is not conducive to environmental protection, and the pollution to the environment is also very large, so I also recommend using this softer iron sheet, you can use it outside the glass Set a few times, it can be used repeatedly, it will not be eliminated, and it will not cause pollution to the environment."

"Of course I'm just giving advice, Mengmeng, you can refer to it or not."

Jiang Aiguo had already walked downstairs with Mengmeng's pen, while Mengmeng returned to the room, leaned on the bed and started chatting with Dabao.

By the way, let's take a look at what the plastic looks like, and what is the material of the plastic?

Because Jiang Mengmeng doesn't have enough points, and plastic pollutes the environment very much, so it is very expensive to buy with free points.

According to what Dabao means, the main brain hopes that the plastic will appear in her world as soon as possible, which is why she marks the freedom point so high.
