Cheng Haitang hurriedly returned to his small study and took out three yellowed books under the bookcase, all with three big characters on the cover: Luban book.

I don't know where the master got this book, there are three volumes, the upper volume is some strange door manufacturing buildings, and the middle and lower volumes are some medical methods, Taoism and witchcraft, which are miraculous. The master told Begonia, don't read this book, let alone use it. It is said that the above medical skills are more like black witchcraft, which cannot cure people, but will kill people.

However, Begonia not only used it, but also used it to save the lives of Xie Yuanyu and Xie Ruijiao.

Haitang put the middle and lower two volumes on the table, and only took the upper volume, ready to give it to the second child. Xie Ruijiao happened to come back and saw Haitang holding a yellowed old book, and when he took it, he smiled: "I've heard you say it a few times, and it's the first time I've seen it look like this today." What are you doing when you come out of this book? ”

Xie Ruizhu listened to Haitang's thoughts, he casually inserted the three "Luban Books" on the bookshelf, and asked Chang Le to go to his study and bring two other books, one "Qi Min Yao Shu" and one "Mengxi Pen Talk". The three different books, Begonia didn't think to collect them, so they kept sticking them on the shelves.

He smiled and said, "These two books are both natural and technical, if he likes them, let him read them." Yun Xuan took you, now you are quirky enough, if you give him those few immortal books, I am afraid that our palace will not be able to keep it. Still is...... Leave it to yourself. ”

When Yunxuan was almost four years old, Xie Ruizhu and Haitang had three princes.

The emperor is in charge of the crown prince, the queen is in charge of the third child, Xiao Yunqi, and the second prince Yunxuan has to create his own sense of existence.

On this day, five-year-old Xie Yunxuan asked for saltpeter from his mother.

Haitang asked strangely: "You don't make gunpowder, and you don't heal diseases, what do you want saltpeter for?" ”

"Mother, you give it to me, the more the better!" Xie Yunxuan said mysteriously: "I can't say it now, I'll play a trick for you!" ”

Haitang was watching the third prince Xie Yunqi take a wooden spoon to eat, Yunqi heard it, he didn't eat anymore, he held the wooden spoon in his hand, stood up and was about to leave, and said: "Trick, trick......"

Haitang grabbed the restless Yunqi, and had no choice but to let Ji'er go to the pharmacy to get some saltpeter for Yunxuan, and then watch how he played.

Yun Xuan got a bag of saltpeter, he asked Chang An to bring a bowl of water up, put the saltpeter into the water, only to see the saltpeter slowly melt in the water, and the bowl of water gradually turned into ice!

"Yikes! What a trick! I only know that saltpeter has the effect of tackling tough problems, detoxifying and reducing swelling, but I don't know that it can form water into ice! Ji'er exclaimed: "I'm afraid that the second prince is not the reincarnation of an immortal, right?" Know everything! ”

"What's this? There are so many miraculous things recorded in the "Dream Creek Writings" that my father gave me! The second prince looked at the ice in the basin and said with some worry: "Although saltpeter is non-toxic, this ice is not delicious......

"What's so hard about that? Ji'er, go and take out the Fen Ge Ding where we ate hot pot to the second prince. Haitang walked over with Yunqi in his arms and said.

So the second prince, with the help of his mother, made a bowl of edible ice by himself, and Cai Lian brought fruit juice and sugar, and poured it on Yun Xuan's ice.

The third prince in Shuang'er's arms was about to rush forward with his bullish strength: "Eat ice!" Eat ice! ”

In a mess, the emperor and the crown prince returned.

Xie Ruijiao smiled and asked, "What?" The second and third are grabbing food? ”

"Father, brother, look! This is the ice I made! Yun Xuan hurriedly said: "The method you recorded in the "Dream Creek Writing Talk" you gave me. ”

"Oh? This is a new thing, it is not enough to rely on cellar ice in midsummer, if you can make ice in the summer, then you will share your father's worries! Xie Ruijiao encouraged. The second child likes new things, which is a good thing. On weekdays, if there are any strange Western things in the palace, the emperor will pick them first.

The prince's brother also felt strange, and walked over to take a look, Yun Xuan was proud in his heart, and hurriedly demonstrated it again on the spot. Several people saw it with their own eyes, and they all thought it was magical and interesting.

With the encouragement of his father, since then, the second prince has been more active in doing all kinds of strange experiments.

Feng Mingze and Jiang Saihua also have a pair of children, the son's name is Feng Qi, he doesn't like to read any four books and five classics, so he likes to tinker with the pile of treasures in his father's private collection. He was the same age as Yunxuan, and the two were not yet ten years old, so Feng Qi poked Xie Yunxuan out to travel.

Feng Mingze listened to the emperor's casual sentence before the noon dynasty, and when he went home, he beat Feng Ji: Poke the fire prince out on a trip? Your dad will beat you into sleepwalking!

can't go out, Yun Xuan is tossing new tricks in the palace.

Yun Xuan saw that the Queen Mother's legs and feet were inconvenient, and she had to be carried outside to bask in the sun, so he drew a picture of the wheel and asked Chang An to go out and find someone to do it, and then he installed the wheel on the Queen Mother's chair, and the chair could be pushed. Later, he and Feng Qi made many improvements, and finally made a stable wheelchair.

The Queen Mother finally breathed a sigh of relief: This time I finally can't push it over, and again, my old bones will be handed over to this great-grandson!

Yun Xuan saw that the queen mother often boiled some ointment with medicinal materials to let them scrub their teeth with willow branches, so he found a bone, pulled out the unused bristle pen in the study, inserted it into the handle of the bone grinder, and then went to brush his teeth with the ointment of the queen mother. Now, not only are the teeth brushed clean, but it is not easy to poke the flesh.

The emperor didn't feel sorry for his new brush at all, and saw that the toothbrush made by his son was really good, but the hair on the brush was too soft. The emperor asked people to find short and hard bristles to make bristles, so that the cleaning effect of the toothbrush is better.

At this time, everyone in Xuanyun Palace began to use the toothbrush invented by the second prince and improved by the emperor.

In order to distinguish whose toothbrush it was, the palace people made different handles out of bamboo, wood, and animal bones. Later, it became more and more refined, and the handles became varied.

Once Gu Mansheng came to the palace, he accidentally saw a toothbrush, so he asked curiously: "What is this new thing?" Still have pig hair on the bamboo? ”

Haitang said with a smile: "This is a small tool that Yun Xuan came up with, applying the ointment used to clean and sterilize to the mane, used to brush his teeth, and his teeth are brushed very cleanly, which is much better than the willow branches used before." You can bring two back and try them, and if they think they work, just ask them to do it. ”

How could Gu Mansheng not want it? Even begonias made of honeysuckle, herbs, green salt and clove bark brought back a lot of ointment. Soon, the Cheng Mansion and the Shen Mansion also used the toothbrushes invented by the second prince.

I love to follow the trend in the capital, not to mention that this is still a new invention of the prince and the emperor, no? Isn't it too shameless? As soon as they meet, they like to ask, "Did you brush your teeth today?" Didn't you brush it with a prince's toothbrush? Then please stand five steps away and don't talk to me. ”

From the capital, it spread to dignitaries and nobles all over the world, and the bristle toothbrush became a popular tooth cleaning tool in the Celestial Empire.

The second prince Yunxuan grew up so eccentric. Take a look at the latest chapter of "Fengqi Begonia Claw Book House" and read it for free for the first time.
