Under the intentional guidance of Zhang You, the old and the young decided to open up history, and immediately prepared.

In fact, Zhang You has been deducing this matter in his mind for a long time, in fact, he already has a general direction, but the most difficult thing is that the airtight material is not easy to solve, who knows the problem he thought, Guo Zaoqing quickly found a way to solve it - silk and tung oil.

Tung oil is a special oil tree species in China - tung oil seeds extracted oil, is an excellent dry vegetable oil, with fast drying, light specific gravity, strong adhesion, heat resistance, acid resistance, alkali resistance, anti-corrosion, rust and other characteristics, is very widely used.

Zhang You is no stranger to tung oil, many places in later generations will use this thing, the reason why he didn't expect it, in his subconscious, such a high-level thing, should not appear in this era, listen to Guo Zaoqing's explanation, only to find that he really underestimated the ancients - maybe he is very familiar with the Ming Dynasty figures or major deeds, when it comes to this kind of corners and corners involving people's livelihood, he doesn't know much, after all, history and him, is just a preference, not a medical skill, is the means he relies on to survive.

Because of these common sense little things, through these days, he has not been less hit, for example, when he first considered the plan to make a fortune, he was like the protagonist in many travel works, he considered making perfume and soap, and so on, and later learned that not only did he have perfume in this year, but even soap, there was already such a thing as pancreas, and Zhangfu used to wash with pancreas mixed with spices.

By the way, tung oil seems to be the main ingredient for making soap, right?

His mind was deserted again, and when he came back to his senses, Guo Zaoqing had already asked people to buy tung oil.

"Jia Lin, do you want to go back to Long's house with me?" It's so close, you should go and see Li Quanfu and his wife anyway, not to mention that in Zhang You's conception of the hot air balloon, Li Carpenter's craftsmanship is indispensable.

Zhang Jialin is fascinated, but she is a little embarrassed, to put it bluntly, although she is more rebellious than most of the ladies, but after all, she is a young girl with a tender face, although she is willing to do it in her heart, the discussion of the world style is still something she has to take into account.

"Let's go, let's go, the spring is bright, isn't it a waste of this good spring * light at home?" Zhang You took the lead, Zhang Jialin hesitated for a moment, but in the end she still followed, Chun Xing wanted to speak and stopped, but after all, she didn't say anything.

The three of them took the path to Long's housework, and happened to pass by the waterhole, but they saw that the frost was hanging in the shade, and a few plum blossoms were standing next to them, and they were blooming. Seeing this, the two little girls had forgotten their embarrassment and ran over to pick plum blossoms in surprise.

Touching the scene, familiar poems involuntarily came out of Zhang You's mouth: "The wind and rain send spring back, the snow welcomes spring, it is already a cliff with ice, and there are still flowers and branches." Pretty doesn't compete for spring, only reports the spring, and when the mountains are full of flowers, she laughs in the bushes. ”

The voice came along the warm wind, Chun Xing only felt that the word was wonderful, but Zhang Jialin's heart was shocked, her cheeks were hot, and she held the plum blossom that was folded off and praised: "It turns out that the world brother is not only good at medicine, but also good at writing, listening to your Yongmei work, the little sister immediately remembered Lu Fangweng's song of the servant operator Yongmei, all of which are Yongmei's masterpieces, but the word is too sad, but the world brother made the opposite of its meaning, the words are upright, the momentum is high, among the many Yongmei works, I am afraid that there is no other." ”

Zhang You was very ashamed, he really didn't mean to "plagiarize" the great man, and hurriedly said: "This word is okay?" It's a pity that it's not made for my brother.,Although my brother thinks he's also a little literate.,Such a masterpiece.,But I definitely can't make it...... Let's go, it's not far ahead. ”

Zhang You is a person who has come over, understands the little girl's thoughts, guesses that the word just now is afraid that Zhang Jialin will misunderstand, and has the heart to explain two sentences, but is afraid that Zhang Jialin will not let go, so he simply changed the topic and walked in the direction of Li Quanfu's house first, Zhang Jialin followed behind in confusion, and thought to herself: This word is obviously what you did just now, why don't you dare to admit it? Could it be ......? Her cheeks suddenly burned, and she shook her head slightly, and she didn't dare to think about it.

Seeing that Zhang You actually brought the daughter of the old man into the house, Li was surprised and delighted, while making tea and pouring water, he called Li Quanfu to buy vegetables, his smile never broke, his eyes moved from Zhang Jialin to Zhang You, and then from Zhang You to Zhang Jialin, secretly gave a thumbs up, and said in his heart that Brother You is really good, look at this meaning, I'm afraid it won't be long before I have to eat the wedding wine of the two, right?

With Mrs. Zhang's reward from the previous time, the lunch was very rich, Zhang Jialin was beautiful, eating in small bites, and looked a little shy. Zhang You didn't care about her, and said while eating: "The child just bought a house in the town, and when he comes back this time, he will pick up your second elder to enjoy happiness." ”

Li Quanfu and his wife first refused, unable to resist Zhang You's sincere invitation, and finally agreed.

Guests and hosts have fun.

After the meal, Li accompanied Zhang Jialin to chat, and Zhang You ran out to watch Li Quanfu make the coffin - he was about to move to the town, and the new customers naturally would not receive it, but the ordered coffin had to be completed.

"Grandpa's hands are so skillful, the wood is like dough in your hands, you can fiddle with it as much as you want."

"Do a lot of work, I'm afraid of any craft." Li Quanfu said honestly, with a smile on his black and red face.

"Can you make a wooden car like this?" Zhang You asked, while drawing on the ground with a small wooden stick, his drawing ability is average, but simple geometric three-dimensional figures can still be drawn.

He drew a four-wheeled cart with a long pole erected on it, which looked a little weird. Li Quanfu stopped what he was doing, squatted over and looked at it for a moment, frowned, and said, "It's easy to do, but what is the top one for?" ”

"Hang something...... Such a car needs at least four cars, four wooden poles, and at least hundreds of pounds of weight! Zhang You said, thought about it, pointed to the top of the vertical line and said: "It is best to make a movable hook here, use the rope to control it at the bottom, and gently pull it, and the hook can fall off with the hanging things." ”

Li Quanfu pondered for a moment and said, "It's simple, just install a message machine...... But what's hanging on it? Why can't I think about it for a long time? ”

Zhang You smiled and said mysteriously: "Don't ask, you'll know when it's done." By the way, if you can make such a wooden car, can you do this? As he spoke, he roughly drew the appearance of the wheelchair on the ground in his memory, and explained as he painted: "It's better to have an extra ring on the wheel...... The backrest should ideally be repositioned back and forth......"

The more Li Quanfu listened, the brighter his eyes became, and finally looked at Zhang You and said, "Why do you have such a brain?" Isn't this a wheelchair used by people with inconvenient legs and feet for the rich, why didn't I think I could make an extra disc and push it by myself? ”

So you have a wheelchair this year?

Zhang You was stunned......
