After pouring the water, Su Qinghua retreated to the study, listened attentively, and then remembered Du Zhili's voice outside: "Dare to ask Brother Yang, what is the ratio?"

"The ratio is divided, and the density is the mass divided by the volume!"

"Divide?! Oh, I see! Yes, yes, the heavier it is, the looser it is, like wood and iron, and the density of Gaine is also! ”

"Exactly."

"Brother Yang is really talented, which makes me pause! It's just that I still don't understand a little, so please give me advice from Brother Yang. ”

"Lord Du is polite, please speak."

"Just now Brother Yang said please float, then naturally stop sinking, but a few days ago I was at the temple fair, I saw an iron boat floating on the water, according to Brother Yang's theory, the iron should sink in the water, I don't know why this iron boat? The iron ship was made by Brother Yang, right? ”

Hearing Du Zhili's words, Su Qinghua only felt a 'bang' in his heart......

Hearing Du Zhili say this, Shen Shixi and Liu Mang were also stunned, they didn't expect that the words that came in and sang would actually be written by Yang Bin, and then their eyes all looked at Yang Bin, shining brightly, like a treasure.

Yang Bin was also stunned, but he didn't expect Du Zhili to be so good at reasoning, and his reasoning was very correct.

He wanted to be humble, and then admit it, but then he thought about it, these brothers-in-law wrote love letters to girls, and it was really funny to spread it, and Su Qinghua was in the house, and his personality was also decent and serious, if he admitted it in person, although he entered the house now, if he admitted it in person, it would not be possible to knock her out of the house.

Moreover, it seems that this is a bit against social morality, and it is difficult to say whether it will affect the qualification of 'student'.

"Be rigorous in doing things, and be reliable in your sister!"

Thinking in his heart, Yang Bin waved his hand and said, "Master Du is too worried, but I didn't write that word, it's just that the reason why this iron boat can float on the water involves another concept." ”

"Oh, please Brother Yang to solve my doubts!"

Su Qinghua was slightly disappointed when he heard this, but then he thought about it, if this word was really written by Yang Bin, and the signature was Su Tong's, "Then what are they doing?" ”

Su Qinghua's eyes widened in disbelief.

At this time, I heard Yang Bin say: "This involves a more concept - force!" Force is everywhere, there is buoyancy in the water, the springs on the car have elasticity, and the iron has gravity......"

"Oh, no wonder the car...... What is Gravity? ”

"There is this basic attraction between all things, and gravity is the attraction between things and the ground, like fallen leaves returning to their roots......"

……

After pouring a glass of water again, Su Qinghua made a salute and retreated,—— it was almost noon, so of course the distinguished guest had to explain to the kitchen! Although she didn't know why Du Zhili would help Yang Bin, she felt that Yang Bin would definitely ask.

And when he walked outside the door, he saw that the pillar was looking up at the sky, and muttered: "There is a basic attraction between all things, so is there an attraction between me and Xiaocui, Master used to say that I was a stupid thing." ”

……

Su Qinghua reserved the best private room, and next to the private room, there were Liu Shiming, Ding Ming, Wan Pandou and others. Of course they're here to see the fun!

At this time, they were talking.

Wan Pandou: "I didn't expect Master Du to really come, it seems that kid has some skills!" ”

Ding Ming: "What are you capable of!" That question is just a brain teaser on the basis of Brother Liu's original question, he is called Hanako, he must not have real talent and real learning, look at it, Lord Du will definitely be disappointed! ”

Wan Pandou: "Yes, arithmetic is so profound! ”

Shen Hanshan: "No matter how profound arithmetic is, it can't compare to articles, everything is inferior, only reading is high!" ”

Liu Shiming was silent, the folding fan in his hand shook gently, but his heart was burning with jealousy.

At this time, Wan Pandou, who was standing next to the back window, folded his fan and shouted: "Lord Du is out, hey......"

Ding Ming: "What? ”

"Look!" Wan Pandou pointed out the window.

Liu Shiming, Ding Ming, and Shen Hanshan immediately rushed to the window, raised their eyes, and immediately fell silent.

In the corridor downstairs, Yang Bin was talking with Du Zhili, walking side by side, Du Zhili's waist was slightly bowed, and their top boss Shen Shixi was behind the two, although Liu Mang was in the end, he was chic.

……

"Brother Yang's talent can be my teacher, today I have benefited a lot, borrow flowers to offer Buddha, I salute Brother Yang a cup!"

"Your Excellency has won the prize, please, please!"

"Brother Yang, this wine and food is really a must, I will eat it after eating it that day, and then eat others, the taste is the same as chewing wax."

"Carving Insect Little Skill......"

……

The laughter came next door, Liu Shiming, Ding Ming, etc. were silent, like sitting on pins and needles, wine and food were at the table, but the taste was the same as chewing wax, after listening to it for a while, I finally couldn't help it, and retreated halfway.

……

Full of wine and food, sent Du Zhili away, taking advantage of Yang Bin's toilet skills, Shen Shixi arched his hand to Su Qinghua, and said embarrassedly: "Mrs. Yang, Yang Gongzi is a pedantic and a man, full of knowledge of things, his talent is a hundred times better than me, I can't teach him, I'm ashamed!"

"Knowing things? Is the knowledge of things a sage? ”

Su Qinghua said the doubts in her heart, she listened to the conversation between Yang Bin and Du Zhili just now, but one thing is certain, she must have heard what the talents usually say.

"The knowledge of things is not the study of a sage, but a reason, a hundred reason, Yang Gongzi is smart and intelligent, as long as he usually studies more." Shen Shixi replied.

"Just what do you study? I hope you will let me know. ”

Su Qinghua was a little uneasy, and continued to ask persistently, after all, no matter how smart you are, you have to use it in the right place!

"This, I'll make a book list for Yang Gongzi."

"I'm sorry to trouble Lord Shen, Lord Shen is here, please."

Su Qingti bowed, took Shen Shixi to the counter, and asked Laixi to bring a pen and paper.

Shen Shixi wrote a large sheet freely, and after writing, he put the pen down, and then said: "The emphasis on learning is accumulation, and after memorizing the books on this, it will be almost easy to understand it thoroughly!" I believe that with Yang Gongzi's intelligence, it is not difficult to understand. ”

After that, he picked up the paper and looked at it carefully, "Since this Yang Gongzi is smart, this endorsement is naturally as good as possible, and if you read more, you can also bypass it roughly." ”

Thinking about it, Shen Shixi added a few more strokes to the paper, and then left slightly drunk.

Subsequently, the news that Lord Du came to visit Yang Bin spread in Shangyuan County......

……

Yang Bin came out of the toilet, but saw Su Qinghua standing at the back door of the kitchen, his white face was like ice meeting Chunyang, and he was smiling and waving to him.

"It's changing so fast! Lost in love with me so quickly......"

There seemed to be a thousand worms wriggling in his heart, breaking through the cocoon and turning into butterflies, and Yang Bin hurriedly rushed over.

When I walked up, I was greeted by a large piece of paper.

"What is this for?"

Yang Bin was stunned, but he heard Su Qinghua's voice like a finch in the clouds: "Xianggong, this is the book list that Lord Shen gave you, he said that the second uncle above is almost able to understand it thoroughly after memorizing, and he also said that knowledge should be focused on the accumulation of ordinary times, you usually have to memorize more when you are fine......

Yang Bin hesitated to take it, and looked down to see that it was densely packed with about one hundred and ten books.

"Oh my god...... No wonder there are so many white heads! ”
