Don't hear what's going on outside the window!

This is not Li Kang's style, since the Xiangguo Temple came back from selling books, Li Dang had to go to the bookstore every once in a while, buy a tabloid and come back to see.

On this day, he read a lace news in the tabloids, saying that Peng Yuanwai of the Peng family lacquerware shop near the Daxiangguo Temple was stolen by thieves a glass vase, and he was distressed and willing to pay a thousand yuan to redeem the vase.

A vase was worth a thousand yuan, and Li Kang's brain cells quickly became active.

In his previous life, he had an accident due to a medical accident and stopped working as a doctor, so he and a few friends opened a glass shop at home, imitating jade and selling it in a scenic spot. The porcelain workshop of the Song Dynasty is already very advanced, as long as you come to the next one, slightly transform, use it to burn glass, make glass, think about it is not too difficult.

Li Dang held the bulky steel syringe in his hand, and thought to himself that if it were changed to glassware, it would be much lighter. Moreover, a glass vase is worth a thousand yuan, if you can fire glassware and glass utensils, then you can easily make a bowl full of plates.

Li Dare smiled, as if it was already raining copper coins in front of him.

Wen Wan was coming in from outside at this time, and when she saw Li Kang holding a syringe in his hand, the corners of his mouth raised, and his teeth cracked, she thought that Li Kang had found a way to cure Wen Kang, and she was overjoyed in her heart.

Seeing Wen Wan come in, Li Dang restrained his smile, he pulled Wen Wan in, smiled and said, "Come, come, Wan'er, didn't you say that you want to be the female shopkeeper in charge of the accounts, Brother Li will teach you the ninety-nine multiplication formula." ”

"Ninety-nine formulas?"

Wen Wan didn't want to mention how disappointed she was, she originally thought that Li Kang would tell him the good news of treating Wen Kang, but she didn't expect that Li Kang wanted to teach herself what mantra table, and she smiled so happily.

"Ninety-nine-eighty-one!"

Li Dang took out eighty-one copper plates, divided them into nine piles, and asked Wen Wan how many they had in each pile. He wants to teach Wen Wan the knowledge of arithmetic, he feels that he will definitely have a lot of money in the future, and he needs Wen Wan, the master of the house, to help him take care of it.

Wen Wan looked at the pile of copper coins stacked on top of each other and shook her head blankly.

No, I haven't taught multiplication yet, how can I be gentle and divide Li Dang found that he had made a mistake, and he asked again, there are nine copper plates in each pile, there are nine piles in total, and how many copper coins are there in total.

"Eighty-one, ninety-nine eighty-one!" A sly smile appeared on the gentle pretty face.

"Yes, yes, Wan'er is so smart, reward a kiss!"

Li Dang kissed him heavily on the gentle cheek, and then taught "Ninety-Eighty-Seventy-Two, Ninety-Seventy-Sixty-Three......

Wen Wan only felt that the place on her face that had been kissed by Li Dang just now was crispy and itchy, how could she have any heart to memorize the mantra that Li Dang taught her.

"Ninety-eight-seventy-three!" As soon as Wen Wan thought about it, she realized that she had misremembered, she smiled and added, "Ninety-eight seventy-three is one less." ”

In Li Dangkai, it is a very simple multiplication formula, and Wen Wan has memorized it for a night and still has not memorized it.

"Come, let's put down this arithmetic first, Brother Li will teach you geometry?" Li Dare saw that Wen Wan couldn't memorize the formula for a while, and wanted to teach Wen Wan some plane geometry knowledge to relax her brain.

"Is there a difference between this arithmetic and geometry?" Wen Wan looked puzzled.

Only then did Li Kang remember that there was no term "geometry" in the Song Dynasty, and this term was first used by Song Guangqi, a scientist in the Ming Dynasty.

"Oh, oh, big brother will teach you points, lines, and surfaces! This is the point, this is the line, this is the surface! ”

As he spoke, Li Dang used his fingers to draw a dot, a line segment and a square on the table.

Wen Wan is still full of question marks, does this Brother Li want to teach himself painting knowledge, his painting skills are much better than Brother Li, you see how dull his square painting is.

Li Dang finally made Wen Wan understand the difference between obtuse triangles and acute triangles, and he encouraged Wen Wan a few words, saying that Wen Wan was talented and intelligent, and she had learned enough mathematics today, so it was time to rest.

"By the way, why did Wan'er come to Brother Li late, is there something to tell Brother Li?" Only then did Li Dang remember that Wen Wan was unusually today, and she came to her room to find her at night.

"Only now do you know that people are looking for you?" Gentle and coquettish.

Then Wen Wan told Li Dang that Li Dang went to Cai Bian's mansion with Qin Guan in the morning. The Wen family came with an uninvited guest, a well-known matchmaker in Bianjing City.

She came to help Cai Han, the third son of the right prime minister's family, propose to the Wen family, saying that Cai Gongzi is willing to marry Wen Wan as his wife, and the dowry is ready, as long as the two get married, Wen Kang can also be taken into the prime minister's mansion to support, Cai Han also said that he would find the best doctor in Bianjing City, and the imperial doctor of the Hanlin Medical Office can also help Wen Kang treat his illness.

This Cai Han really wants to become his rival in love, Li Dang felt a little uneasy in his heart, and he asked Wen Wan: "What does Madame think of this matter, did she agree?" ”

"My mother would agree, of course she refused, and the matchmaker still wanted to chatter, and was invited out of the house by my mother!"

Wen Wan felt very happy when she saw the nervousness on Li Kang's face, and she told Li Kang in detail how Mrs. Wen rejected the matchmaker.

"What does Wan'er think about this, don't you want to be the prime minister's daughter-in-law?"

"Brother Li said with a smile," Wen Wan's face was gloomy, didn't Brother Li still understand Wen Wan's intentions, she continued, "What will Wan'er do to be the prime minister's daughter-in-law?" ”

"What's so rare about Wan'er?"

Li Dare salivated and looked tactful and gentle.

"Nasty!"

Wen Wan also found that Li Kang was making fun of herself, and she raised her fist and gently hit Li Kang's chest.

"Woo woo...... Wan'er doesn't really hate Brother Li, right?" Li Dang stroked his chest with his hand, looking in pain.

"It's just annoying!" Of course, Wen Wan knew that Li Dang was pretending.

"Then what does Wan'er want Brother Li to do so that she doesn't hate Brother Li?"

Li Kang's hands began to become dishonest again, he wrapped one hand around Wen Wan's slender waist, and the other hand played the piano on Wen Wan's green bandeau chest.

Although Wen Wan is only seventeen years old, a pair of jade peaks are already tall, strong and elastic.

Li Dang closed his eyes, felt the ecstasy and beauty of his fingertips, and moved his mouth towards Wen Wan's face, and suddenly Li Dang found that Wen Wan's pink face was a little strange, cold and cold, and there was no temperature, he opened his eyes and looked, it turned out that Wen Wan didn't know when he brought a metal syringe and stuffed it into his mouth.

Just when Li Kang was stunned, Wen Wan took the opportunity to break free from Li Kang's embrace, she quickly flashed to the door, turned back to Li Kang and said, "It's late at night, Brother Li should rest early." ”

Seeing the disappointed expression on Li Kang's face, Wen Wan said again: "In this life, Wan'er and Brother Li don't become parallel lines that will never intersect, Wan'er and Brother Li will become intersecting lines, and they will be together all the time." ”

Li Dang was stunned, this little girl actually used the geometric knowledge she had taught to learn and use it to show her heart.

"Brother Li too, but Big Brother wants to be with Wan'er now." Li Kang has already been obscene and unable to control himself.

Wen Wan heard the meaning of Li Kang's words, her face turned red, she buried her head, hurried back to her boudoir, stroked her rapidly undulating breasts, and drank a pot of tea.
