Only then did Yang Wang and the others clear their doubts, it turned out that they were all filled with these small round boxes. I just don't know what is in the small round box, what did Li Feibai take these small round boxes to Kaifeng for?

Li Feibai divided the small wooden box among the three of them and said, "This is a new thing I made, called Cool Oil, which has a miraculous effect on mosquito bites. Brother Yang, you open the box, stick a little stick to the itchy area, and it won't itch after a while! ”

Yang Zhen opened the box and wiped it a little on the itch, only to feel that it was extremely cool and comfortable!

Li Feibai saw that there was a small injury on the back of Wang Yaojian's finger, and the injury was not big, but there was some redness and swelling around him, so he said, "How did you get injured there!" ”

Wang Yaojian said: "Yesterday, I was doing carpentry work, and I accidentally let the file touch it. ”

Li Feibai said: "The cooling oil also has the effect of relieving pain and reducing inflammation, you can try it by applying a little." ”

Wang Yaojian also stuck a little bit and smeared it around the wound.

Qin Meng was holding the box and sniffing it at the end of his nose, and saw that Wang Yaojian and Yang Zhen had opened their own boxes and opened their own boxes. There was no itch on his body that had been bitten by mosquitoes, nor was there any injured area, so he went to smell the ointment inside, and when he smelled it, he was refreshed and very comfortable.

Li Feibai said: "By the way, the cooling oil also has a refreshing attack effect." You apply some under your nose and temples for better results! ”

Qin Meng wiped some in each of the three places, and said with a slightly exaggerated expression: "Comfortable!" ”

Li Feibai said with a smile: "The three of you will tell me, this thing will be sold in Kaifeng, how much can one sell for!" ”

Wang Yaojian was obsessed with carpentry, and he had never gone out to buy anything, so he had no idea what things were sold at what price, so he said casually: "Can you sell for forty or fifty yuan?" ”

Yang Zhen was disdainful in his heart, and said secretly: "This is something that Lord Li made carefully, and you actually said that it is only worth forty or fifty yuan, and you look down on Lord Li too much." He said: "Such a good thing, it can relieve itching, pain and refreshment, I think it can be sold for one or two." After a pause, he said: "I'm afraid that one or two will be cheaper, and I may sell it for three or five taels!" ”

Li Feibai shook his head secretly, turned his head and asked Qin Meng, "How much do you say it can be sold!" ”

Qin Meng said: "It depends on who you sell to?" Sold to rich people, forty or fifty wen is a bit low, and one or two is a bit high. Selling to people who have no money, forty or fifty wen is a bit high, and if it is sold for ten or eight wen, someone must still buy it. ”

Li Feibai said secretly: "It's still Qin Meng's sincerity, which is similar to what I expected." However, what Yang Zhen said is not impossible, so we have to make some articles on the packaging of the cool oil, such as the box is made of gold, silver and jade, and some other spices are added to the cool oil, which makes people smell different from only selling ten or eight cents, and it is estimated that some people are willing to buy it. Just like the luxury goods of later generations, it is expensive in one word, but it can also be sold. When I come back, I have to make a fuss about this, and divide the cool oil into three, six, nine and so on. He said, "I'm going to sell this thing for ten cents a piece." The three of you can use what you can, tell your neighbors, and if you can sell it, I will give you a commission. Sell one and get three pennies. ”

Wang Yaojian is just a small clerk in the workshop. Although he fantasizes about being an official like a warden in the future, he is extremely honest and will not make benefits for himself in building and repairing houses, and he has no position or power and no additional income, and lives on only work, food and silver, and lives extremely difficult. I heard that a cool oil can make three cents, and I couldn't help but be moved, thinking about how much money I could make if I sold 180,000 boxes of cool oil a year. The result surprised him very much, he could earn 300,000 yuan, which was a full income of 300 taels, and he couldn't earn this amount in a lifetime in the workshop.

He immediately decided that after returning from Kaifeng, he must move around more and sell the cool oil to everyone he knew.

Yang Zhen, as the old man of Daxiku, can still make money, and he will not be moved by the benefits of the three cents if he is financially generous. It's just that he thinks that Li Feibai won't say such a thing for no reason, and he will buy a 1,2000 box no matter what when he comes back. That's how much it is, but it's just a matter of ten taels and twenty taels, and it is worth it to spend this little money to buy Li Feibai happy!

At this time, Wang Yuexuan hurriedly came with Li Shizhen in her arms. As soon as Li Shizhen saw Li Feibai, he said, "Let's go to Kaifeng?" ”

Li Feibai said: "Let's go!" ”

Li Shizhen clapped her little hands and said, "Okay, I can finally go out to play!" ”

Wang Yuexuan warned: "Give me a good look at Shi Zhen, dare to bump into it, I won't be done with you when I come back!" ”

The people immediately set off, and when they went out of the city, they met someone at the gate of the city who set up a stall to sell meat and steamed buns, and each person ate one or two for breakfast. Li Feibai wanted to see if Qin Meng could eat twenty-eight, so he asked Qin Meng to eat unlimited amounts, but Qin Meng ate sixteen, so he rubbed his stomach and said, "I ate a little bit last night, so I can only eat so much!" ”

Except for Yang Zhen, everyone else is smacking, and the happiest is the stall owner, who never dreamed that he could sell more than 30 meat buns when he opened a shop.

Out of the city, Yang Zhen and Wang Yaojian took a car and walked in front of the road. In the middle, followed by a truck loaded with Jiyuan's specialties, followed by a slightly luxurious car in which Li Feibai and Li Shizhen were sitting.

Originally, Li Feibai didn't plan to let Qin Meng follow. After all, if you go to Kaifeng and Pingchuan, it is impossible for there to be bandits robbing the road. But Qin Meng said: "I have eaten your food, and I have to protect your safety every step of the way." ”

Li Feibai thought about it, let Qin Meng stay at home and live with Hou Yanmin, it was inconvenient for a lonely man and a widow, so he didn't insist. The three of them were crammed into a car, and Li Shizhen rolled around on Qin Meng's big belly, giggling and shouting that it was comfortable!

Li Feibai looked at the fertile land outside the car window, all barren there, waiting for the season to plant wheat. He didn't think it was a pity, if there was corn in the Ming Dynasty at this time, it would be great, so that instead of planting one season of grain a year, he could grow two crops. Moreover, the yield of corn is large, and the income of farmers is also large, so they will not rebel because they have no food to eat.

Walking and walking, a round of red sun is rising, Li Shizhen looked at the sun as big as a millstone, and talked catchily about the two children. After reciting, he asked, "Brother Feibai, are you saying that the sun is close to us at the beginning of the day?" Or is the middle of the day close to us? ”

Li Feibai saw that the time had come, so he said: "I think the sun is as close to us as the sun is in the middle of the day!" The reason why it is cool at the beginning of the day and hot in the middle of the day is probably because the sun does not shine on us. After a pause, he said: "Shi Zhen, do you know why the sun is round, the moon is round, and the earth under our feet is square, is there a possibility, the earth under our feet looks square, in fact, it is also a big round ball, just because it is too big, we are like a speck of dust on it, so it feels square?" ”

Li Shizhen was silent, as if thinking about this question.

Li Feibai saw that there was a play, and then said: "Actually, the sun is not as small as we see, it is very big, countless times larger than the earth under our feet." ”

Li Shizhen clapped his hands and said: "I don't know if the sun is that big, but the moon is not as small as we see, but I know." I thought, since the moon can be big even if it's that small, the sun must be big too. I just don't know if it's as big as you say! ”

Li Feibai said: "Oh, you know that the moon is very big? ”

Li Shizhen said "um", and then chanted a poem: "The mountain is near the moon and the moon is far away, and the mountain is larger than the moon." If someone's eyes are as big as the sky, let him see the mountains and the moon wider! ”
