"Weird!"

Not only Baoyu shouted, but also the girls behind him also exclaimed. Baoyu couldn't bear it, so she simply got up and leaned over to take a look.

Li Weijian smiled and handed the bottle to Baoyu, who held it in his hand and looked at it for a long time, and never peeked through the hidden mechanism. Then he pointed the mouth of the bottle at the water in the jar, but not a drop of water gushed out.

Jia Lan's eyes were hot, but because there was Li Kun behind him, he couldn't bear to step forward, and scratched his ears and cheeks and said eagerly: "Uncle, what is the reason for this?" ”

Li Weijian took the bottle from Baoyu's hand, turned his head and nodded at Xiu Ying: "I won't say the truth for the time being, Xiu Ying, you can demonstrate it again." ”

"Good!" saw Xiu Ying take the bottle, pulled out the stopper and poured the water back into the jar, and then brought a steaming teapot from the east chamber. Pour the hot water from the teapot into the bottle, wait for a few breaths and then spill it out, replug the stopper, turn the bottle mouth upside down to the water in the jar, and the water will be sucked out in an instant.

Jia Lan shouted again: "Uncle, uncle, tell me the truth." ”

Li Weijian smiled and said: "Thermal expansion and contraction, air pressure, these will be learned in the future." ”

Baoyu didn't ask about reason, only tilted his head to talk to Qin Zhong, thinking that he would fiddle like this in the future, and he would definitely bluff a few maids around him.

Most of the girls in the back whispered to the others, but the little girl Tanchun clasped her hands and praised it, saying 'mysterious' words.

After making a fuss for a while, Li Weijian pulled out the cork, this time filled it with water, held the mouth of the bottle with one hand, and turned it upside down suddenly.

What's even more mysterious is that the water in the bottle has not flowed out for some reason. Baoyu pulled Qin Zhong to take a closer look, and after looking at it for a long time, he didn't see the reality.

Li Weijian even took the two toothpicks handed over by Xiangling, and stuffed them slightly from the bottom to the top, and the toothpicks floated and rose. When he wiped the mouth of the bottle with his hand, there was a bang, and the water in it suddenly poured down.

After selling a lot of passes, Li Weijian showed the key points. He showed it as much as the size of the mouth of a bottle, with a hole drilled in it just big enough for a toothpick to pass through.

Seeing that his eldest nephew Jia Lan looked eager to try, Li Weijian ordered Jia Lan to let him try.

Jia Lan glanced back at Li Kun, and when he was bowed, he stepped forward happily. According to Li Weijian's instructions, the bottle was filled with water, sealed with a perforated glass piece, and suddenly turned it upside down, and the clear water in it really did not leak.

Then insert a toothpick through the small hole, and the toothpick floats up.

Baoyu clasped his palms together and praised: "I don't want this real learning to be so interesting, but it's a pity that I haven't known it." Fourth brother thrifty, but there is still a trick on the side? ”

"Yes," Li Weijian said with a smile, "But this time I don't need a bottle." ”

Li Weijian waved his hand, several maids moved the glass bottles and jars together, Hongyu lit rosin, Qingwen brought a cardboard box with holes, Xiuying and Xiangling put the pasted small cardboard boxes into a wall.

The rosin burned in the box, and the smoke filled the room.

Li Weijian adjusted the box to the wall made of cardboard boxes, and said, "Look at my air cannon!" ”

With a slap of his hands, a circle of smoke erupted from the box, and he slowly slammed into the wall of the cardboard box. When it collided, the cardboard boxes scattered in all directions.

"Interesting, interesting!"

At that moment, Li Weijian let go of his body, and let Baoyu, Jia Lan and the girls come forward to try.

After that, he made soap bubbles with rosin, purple alkali and water, lit it with his hand, and splashed it to the sky with blue fire; Then use two iron cylinders to let the iron ball fall from it, shuttle back and forth several times, the iron ball is getting slower and slower, and the careful observation is still rotating in the iron cylinder.

Li Weijian didn't say the truth, but only demonstrated the subtleties of practical learning, which immediately attracted great interest from a group of people. The mysterious little experiment is indeed fascinating, not to mention that it is a boy of the age of Baoyu and Jia Lan, but even a girl like Sanchun, Daiyu, and Baochai are also attracted to it.

Their hearts have their own thoughts, cherish the spring, explore the spring suddenly, it turns out that this is the real learning, really interesting; Although Yingchun also found it interesting, he took this opportunity to look at Li Weijian carefully, and his heart rose when he looked at it;

Li Kun's face was full of praise, her younger brother has been a little old since he was a child, and his father Li Shouzhong once praised him as 'having hills and valleys in his chest', but after she got married, this thrifty brother suddenly didn't get up and went to Maoshan to cultivate for two years, and he got nothing before he returned to the right path. Fortunately, he reformed himself later, and he was selected for a show after just over a year of studying. But I never thought that this time I would stir up the wind and clouds in the Beijing Division, and I would become like this!

Daiyu rarely showed her face, with a smile on her face, watching Li Weijian walk back and forth around the table. I secretly thought to myself, what kind of man is this thrifty fourth brother? This way is obsessed with the career economy, and I don't want to not only study practical learning, have a strategy, but also have poetry and books, and have a delicate mind.

Since he came to Rongguo Mansion, he has helped him several times, Daiyu thought, it's a pity that he doesn't have any brothers and sisters, if he has, he wants to come to his brother is like a thrifty fourth brother, right?

Daiyu's side, Baochai was still concerned about Li Weijian at first, and when she noticed something strange in her heart, she forcibly turned her head and only looked at Baoyu. Seeing its palms and feet, he was overjoyed, and his heart was slightly ironed. Thinking about it, it was not in vain that Brother Bao finally had an interest, and if he succeeded in the future, he couldn't say that he would be able to use this to get a fate.

When it was too late, this practical and interesting lesson came to an end. Li Weijian stood behind the table again, and smiled at everyone: "A few small experiments are quite interesting, and now I will tell you what practical learning is." Practical learning is a study that delves into the inner truth and benefits the world through the truth. ”

Tanchun said: "The previous water company was earned by the fourth brother Jian? ”

Li Weijian bowed his head and said, "Exactly." The water company, well, in the first half of the month, you might as well go to Xinjiekou to take a look, this is a small test. When the study is deep, flying into the sky and turning stones into gold, those techniques that only see their names and do not see their shapes in the Dao Gate will be realized by the practice.

At that time, although thousands of miles away, it can be reached; Far away from the ocean, it can also be like face-to-face; One acre of paddy field can beat thousands of catties of rice; Without leaving home, you can also know the world's major events. ”

There was a lot of discussion at the bottom, some of them yearned, and more of them felt that Li Weijian's rhetoric was exaggerated.

"That's the case today, I just hope that this interesting practical lesson can arouse your interest in practical learning."

At that moment, everyone got up and stepped forward to talk to Li Weijian, this word, that word, after a few words, they dispersed in twos and threes. Only Li Kun and Jia Lan stayed, and Li Kun also led a kind of maid to put the tables and chairs in place, and then entered the main room to talk to Li Weijian.

Hongyu served tea, Li Kun hurriedly poured it for Li Weijian, and said with a smile: "Brother Jian'er drink something to moisten his throat, I just listened to Brother Jian'er's class, but I know that Brother Jian'er has put a lot of thought behind it." ”

Li Weijian shook his head with a smile and said, "The idea is ready-made, but the objects are not easy to find." After a pause, looking at his eldest nephew Jia Lan, who was eager to try, Li Weijian beckoned over with a smile, and asked with a smile: "Brother Lan, do you want to learn real learning?" ”

"Yes!"

Jia Lan's little man, his eyes lit up. Compared with the boring Four Books and Five Classics, this practical learning is too interesting!

Li Weijian said: "Then you are a good student to read and write, and after two or three years, your uncle will personally teach you to learn." ”

"Okay, don't forget when my uncle arrives!"

Li Weijian rubbed Jia Lan's little head with his hand, and stretched out his slap again: "The eldest husband said a word-"

"It's hard to chase a horse!"

Smack-

One big and one small clapped their hands together, which caused Li Kun on the side to laugh and say angrily: "Brother Jian'er has a great future when he comes, where can I teach Lan'er?" Besides, it's enough to find a proper real bachelor to teach, and then Brother Jian will point one or two on the side, but don't spoil Lan'er too much. ”

Looking at Jia Lan pouting, Li Weijian said: "I see that Brother Lan is a smart person, I will give me a little guidance, and Brother Lan will definitely have attainments in practical learning in the future." ”

Jia Lan's tense little face showed a smile and said, "Uncle, don't worry, I will not embarrass my uncle in the future!" ”

Li Kun's mother and son were slightly discussed, and because they had to go to reply to their mother-in-law, Mrs. Wang, the two hurriedly got up and said goodbye.

Li Weijian sent the mother and son to sit on the chair, sipping tea and eating snacks, secretly thinking in his heart, I don't know if Baoyu can learn this time. If you can learn it, it is also a good thing, but Baoyu will still have some use in the future; If you can't learn it...... Scold! When you come, others can see what Baoyu is, right?

He didn't mention how he thought about it, and said that Li Kun led Jia Lan out of the small courtyard in the northeast, and went all the way to the East Corner Gate to send Jia Lan back to himself, and then turned to Mrs. Wang's courtyard.

After Jin Chuan passed, Li Kun entered the inner middle, and saw Aunt Xue and Baochai accompanying Mrs. Wang early. When Li Kun saw the ceremony, Mrs. Wang hurriedly stopped with a smile on her face and said, "It's all your own family, you don't have to abide by complicated rules like this in Su Ri, Brother Zhu's daughter-in-law sit down." ”

It was rare to get the smiling face of her mother-in-law again, but Li Kun felt awkward, and after thanking him, he sat down next to the chair, and then said: "Brother Jian has been preparing for two days, and he really put his mind into it. ”

Mrs. Wang smiled and bowed her head repeatedly: "Yes, Fang Cai Baochai told me." God is pitiful, Baoyu couldn't bear to read those four books and five classics before, so I thought that I was afraid that Baoyu could only be a rich idler, and I didn't want him to have some attainments in practical learning. ”

Li Kun laughed with him, secretly thinking in his heart, but he just found it interesting, and he didn't know what Baochai said, how did he become some attainments in the mouth of Mrs. Wang?

I heard Mrs. Wang say: "I just discussed with my aunt's wife, and I will go to find a few real bachelors in the past two days, and I have to work hard to help my brother choose it." ”

Li Kun should go down, only the Tao is what it should be.

At the moment, Mrs. Wang couldn't help but think about it, thinking that in the future, Baoyu would be motivated, and if she got an official and a half-job, her life would be enough.

Aunt Xue said with a smile: "With Baoyu's intelligence, I don't think the future of the future will be worse than Brother Jian'er." My son, what do you say? ”

Baochai knows that her mother is very unkind to see Li Weijian because of her brother's affairs, but where is the reason for such words to be said in front of Li Kun?

Because it is, he said: "This is too early, if Brother Bao studies hard, he will definitely have a future in the future." ”

Mrs. Wang also felt that her sister's words were inappropriate, and when she saw that Li Kun had a calm face and did not speak, she said, "Brother Zhu's daughter-in-law has also been busy for a day, so let's go back and settle down." Now that you are on an errand, you don't have to come to me every day to make rules. ”

Li Kun responded, then got up and said goodbye. Out of Mrs. Wang's courtyard, Li Kun was extremely disdainful in his heart. She knows Baoyu's temperament, she fishes for three days and dries nets for two days, so she can study hard with such a temperament? Even if you put a lot of thought into it, there are many smart people in the world who learn from practice, but how many people can compare to Brother Frugal?

Look at the situation, Aunt Xue seems to maintain Baoyu as her own son-in-law, but she looks down on the thrifty brother who caused the storm just now, heh! is so blind, no wonder the Xue family has fallen so far!

Li Kun returned home to teach Jia Lan not to mention it, this is the case today, I don't want to miss a person because Li Weijian is in class, and some people in the Rongguo Mansion will be dissatisfied.

Who is missing? is Aunt Zhao's son Jia Huan!

Aunt Zhao only learned about Li Weijian's class later, but she never invited Jia Huan to audit, and scolded Li Weijian at the moment. Immediately, he sent the maid to listen around, and then learned that it was Baoyu who forgot about Jia Huan!

If it's just Li Weijian, Aunt Zhao has scolded her, after all, it's far away, even if she has a thousand means, she can't use it against Li Weijian. But what she forgot about her son was Baoyu, Aunt Zhao's heart suddenly rose, where could she bear it?

When Jia Zheng entered the room from Mengpo Zhai, Aunt Zhao stretched her face, sat on the head of the bed and turned her head, but she didn't look at Jia Zheng.

Jia Zheng wondered in his heart, and leaned forward and said, "What's the matter?" ”

"What else? The wife is too partial, and it is a son who is born only as the jade, but Brother Huan is not. ”

"What do you mean by that?"

Aunt Zhao said aggrievedly: "Today, Mrs. asked Brother Jian to give Baoyu a practical lesson, and Brother Lan and the girls all went together, and they forgot about Brother Huan aside." Master, I've even listened to the Spring Celebration and Spring Greetings, where is my ring? ”

Jia Zheng frowned, he didn't like the set of practical learning in his heart, because he said: "Practical learning is a small way after all, and the scriptures and righteous articles are the right reason." Baoyu's evil obstacle was that he couldn't learn the Four Books and Five Classics, so he had no choice but to try to learn practical learning. Now Huan'er is still young, and he first learned in private school, if he succeeds in the future, I will find a famous teacher for him. ”

Aunt Zhao's heart ironed slightly, got up to serve Jia Zheng and sat down, gently kneaded his shoulder, and said in a small voice: "What the master says has to count." They are all the sons of the master, although they are divided into concubines, but this bloodline is all the master's. If Huan'er is motivated, the old man will also have a bright face in the future. ”

Jia Zheng snorted twice, which was considered to be a promise.

Aunt Zhao kneaded it for a while, and then said softly: "Master, are you still with me today?" ”

Jia Zheng glanced back, and saw Aunt Zhao's face with a spring color, and immediately his heart fluttered, and he said, "Well, I'm not leaving." ”
