arranged for the Yan family to live in the city, but Wang Mai invited the third Yan Qinli alone. This Yan Qinli person www.biquge.info as his name suggests, after chatting for a while, he has already performed three salutes, and Wang Mai can only return the salute according to the rules, which makes him tired, and he will call his second brother out if he knows it.

"Assistant Teacher Wang, thank you for your guidance just now, I didn't expect the world to be really all-encompassing. The microscope just now really presented the world in a drop of water in front of you. Those little insects that are difficult to distinguish with the naked eye are really amazing to look at, please take a prostration. Yan Qinli said and bowed again.

Wang Mai hurriedly helplessly supported him: "Okay, okay, okay, brother Qinli, don't be polite, I'm a junior, you worship me again and again, I really can't afford it." ”

"Chao Dao asked about death," Yan Qinli's face was excited, "If it weren't for Assistant Teacher Wang's teaching today, how could Qinli learn so much knowledge." Take the microscope just now......"

"Brother Qinli, when it comes to this microscope, I haven't finished introducing ...... yet."

Yan Qinli saluted again: "Please also ask Assistant Teacher Wang to teach ......"

"Brother Qinli," Wang Mai smiled bitterly and held him up, "I can say, but can you not always worship me like this, I am an impolite person, and you make everyone very tired like this." ”

"How can that be?" Yan Qinli shook his head, "If you are respectful and rude, you will ...... hard"

"Brother Qinli," Wang Mai stopped, "You listen to me first, etiquette is not a formality, Wang Shichong plotted to usurp the throne, but he treated others with courtesy, even the peddlers and pawns were courteous and said all the good things to please them, do you say this is a real courtesy?" ”

"No," Yan Qinli replied without hesitation, "but ......"

"No," Wang Mai continued, "etiquette is external, and as long as we are benevolent, everything we will naturally do is in accordance with etiquette." Otherwise, even if he is as comprehensive as Wang Shichong, he is not a person who knows etiquette, right? Wouldn't it be nice for you and me to be like ordinary people? ”

"Ordinary people?"

"It's a thank you when you express gratitude, and it's a big deal...... You don't have to bow so badly every time. If you do this again, I will have to flee in the wilderness, and you will naturally not be able to hear about it. "Wang Mai is about to leave.

"Assistant Teacher Wang......"

"Just call me by name."

"Okay," Yan Qinli frowned, "Jikai, since that's the case, please forgive Qinli for being rude......"

"That's right," Wang Mai patted him on the shoulder, "Brother Qinli doesn't care how old I am, why should we be so polite between our brothers?" ”

"What else is there to learn about the microscope? Please continue to teach. Yan Qinli was just about to bow habitually, but suddenly remembered what Wang Mai had just said, and hurriedly stopped.

Wang Mai nodded with satisfaction: "First of all, the optics inside is a university question." ”

"Optics?"

"Yes," said Wang Mai, "is the study of light. If you think about it, it's just a university question. You see, the afterglow of the sunset, the fire of thousands of miles of clouds, why is there such a magnificent scenery? ”

"I don't know ...... below" Yan Qinli looked at the clouds in the west, and his face was reflected fiery red.

"Also, what is the reason why light brings life to all things?"

Yan Qinli shook his head blankly.

"We are born with the presence of light, but what is light?" Wang Mai patted him on the shoulder, "If we can unravel the mystery, does that mean that we will be able to grasp the power contained in the light?" ”

"Mastering the power of light?" Yan Qinli opened his mouth, this person really dared to say it.

"Actually, we've got some scratches of the surface, which is lighting." Wang Mai looked at the gradually lit windows on the side of the street and said.

"This ......"

"Brother Qinli must be talking big about me, but if you think about this microscope, you also understand the principle of it, isn't this a kind of research on light?" Wang Mai said.

"Yes, I thought that the light could only change its course under the reflection of the copper mirror, but I didn't expect that it would change its route when passing through this glass." Yan Qinli said while thinking.

"It's a property of light, and knowing about it, I built a microscope and uncovered the tip of the iceberg."

"The tip of the iceberg?"

"Legend has it that there are countless icebergs in the far north, and when an iceberg floats on the water, people only see the part on the water, and most of the underwater is not visible, and not seeing does not mean that it does not exist." Wang Mai explained.

"An iceberg...... Yan Qinli lowered his head and thought for a while, "You are really rich in five cars, this analogy is indeed very appropriate." ”

"When we came, we were on the way to catch up with the summer harvest, the growth of grains is inseparable from light, if we can uncover the secret of light, can we control the growth of grains, and there will be no hunger in the world?"

"It makes sense," Yan Qinli said, "but if you want to do it, it's not easy to say." ”

"Brother Qinli is erudite and talented, and he must know that there is a big island in Hainan, and there are three counties on the island." Wang Mai asked. There was no detailed map of this era, and he asked for a long time before he learned about the current situation on Hainan Island from Lao Xu.

"Yes, in the third year of the Great Cause, Ding Mao changed Yazhou to Zhuya County, and then analyzed the southwest region and placed Linzhen County. In the sixth year of the Great Cause, the original two counties were relocated to three counties: Zhuya, Dan'er and Linzhen. Yan Qinli didn't think about it, and opened his mouth to tell the current situation on Hainan Island.

"There is spring all year round, there is plenty of sunshine, and it is said that rice can be harvested three times a year, I don't know if Brother Qinli knows?"

Yan Qinli shook his head: "I only heard that it is a place of smoke and miasma, a place where the imperial court exiles criminals, but I don't know much about the appearance and topography here. ”

Hainan Island was not officially included in the administrative region until the Liang Kingdom of the Southern Dynasty, and the yamen had just been set up on the island, and the information that spread to the Central Plains was naturally very small.

In short, this Hainan Island can be said to be blessed with a unique climate, not a miasma of smoke, so the local people do not have to suffer from hard work like the people of the Central Plains, they can have enough warehouses and families without worry. Isn't this a benefit of light? Wang Mai withdrew the topic again.

"Really? How can there be such conditions in this land of Hainan? ”

"Can I still lie to you?" Wang Mai said with certainty, "So the knowledge in this light ......."

"But," Yan Qinli shook his head and interrupted him, "After all, there are only three counties there, even if all the grain is grown, it will not be enough for the people of the world to eat......"

"Not necessarily," Wang said, thinking of the hybrid rice technology of later generations, "the conditions there are also very suitable for crop improvement technology...... Alas...... Let's continue to talk about optics. ”

"Improving crops?" Yan Qinli looked at him, "Please also ask Brother Jikai to give advice." ”

"Okay," Wang Mai sorted out his thoughts, "I only have one or two crops in the Central Plains every year, which means that Si Nong only has one or two opportunities to select and breed seeds every year. If this process is carried out on the island of Hainan, the chances of finding a good seed will be doubled, and the chances of finding a good seed will be greatly increased. ”

"I once studied Jia Sixian's book "Qi Min Yao Shu", and the book said that good seeds are related to the yield of crops, and I also asked the tenant farmers at home, and they also think so." Yan Qinli recalled.

"Brother Qinli, you even read this agricultural book?" Wang Mai looked at him in surprise.

"Qi Min Yaoshu" is a comprehensive agricultural book, which summarizes the agricultural knowledge of the Central Plains in detail, but there is a sentence in the book, "Zhang Renri: 'The four bodies are not diligent, the five grains are not divided, who is the master?'", mocking Confucius for not attaching importance to agriculture, Kong Ying reached the Guozijian After taking office, in order to avoid it, Guozijian's colleagues did not mention this book in front of him, which was a small unspoken rule in the Guozijian.

I didn't expect this Yan Qinli to dabble in such a wide range of books, even reading agricultural books.

"Knowing is knowing is not knowing is not knowing, and knowing is also knowing. Although the Yan family is a protégé of Confucius, they have never been secreted by His Holiness, which is the legacy of his grandfather. Moreover, Jia Sixian's "Qi Min Yao Shu" is a rare agricultural book, and there is no reason to abandon it. Yan Qinli explained.

Indeed, there were so few ancient Chinese scholars who were willing to bend down to study agriculture that a thousand-year-old agricultural country did not leave many agricultural books to be passed on to future generations.

"Agronomy is a university question, it looks inconspicuous, but it is related to the stomach of the people in the world, and agriculture is the foundation of the country." Wang Mai sighed.

"That's right," Yan Qinli agreed, "what you said just now that the climate of Hainan is suitable for breeding, and that is reasonable. If this can really be realized, it will be a great event for the benefit of the country and the people. ”

Originally, I just wanted him to see optics, but I didn't expect to talk about agriculture, alas...... Wang Mai had the intention to bring the topic back, but he was told back by Yan Qinli several times. In the end, I had to tell him what little knowledge I had about agriculture and genetics.

"Rice is male and female, how can we improve it?" Yan Qinli asked. Just now, Wang Mai inadvertently mentioned the high yield of hybrid rice, but he didn't expect it to arouse Yan Qinli's great interest.

Wang Mai struggled to recall the documentary he watched about hybrid rice, and only some remnants remained in his mind: "Some sterile wild rice seems to be unisexual, and this should be solved by using this." ”

Yan Qinli's eyes lit up when he heard this: "Ji Kai is really knowledgeable, not bad, you can start from here." By the way, if it's late today, I don't know where you're going to take me? ”

Wang Mai's heart finally returned to the topic: "How many places does the yamen Qinli brother know about this night's errand?" ”

"Taishi Eunuch?" Yan Qinli thought for a moment and said.

"Not bad." Wang Mai pointed to the gate not far away, "This is it." "I just showed you the microscope, and now I let you see the astronomical telescope, and you know the power of optics.

After Taishi Jian borrowed the astronomical telescope, he never returned it, so Wang Mai had to ask Taishi Ling for a pass, so that he could come over at any time to take a look at his invention. I have to look at my own things now, and I have to find someone else's permission to reason with someone.

However, the observatory in the prison is indeed professional, and the weather is very good, and it is a good day to observe the stars. When I arrived on the stage, I found that there were two Taoist priests who had already been here, and it was Yuan Tiangang and Li Chunfeng who I saw during the day today.
