"Lingnan Road and Johor have similar climates, and the Feng family is willing to try to grow Johor rice for the imperial court in Lingnan, so as to promote the entire Tang Dynasty!"

Feng Zhidai felt bitter in his heart, since there was all hard work left, since this was the case, then the Feng family would do the hard work to the end.

In this regard, Merton did not refute that Lingnan Road is like summer all year round, with high temperature and rain, and it is indeed the best choice for trying to grow Johor rice.

Hearing this, Dasi Nong Su Lingnong put down the rice seed in his hand and nodded: "Lingnan is indeed the best choice, but this rice will definitely be promoted to the entire Jiangnan in the future, it is better to try to plant in Huguang, Suzhou and Hangzhou and other places at the same time, so that there can be a few more places as a reference, and it can also leave experience for future promotion." ”

"Da Si Nong's words are reasonable, so I will do what you say." Li Shimin nodded.

Feng Zhidai's face suddenly darkened, if he tried to plant at the same time in all parts of the south of the Yangtze River, then the only little hard work of the Feng family would be shared by many people, so that even if the rice seed trial was successful in the future, the credit of his Feng family would be diluted to the extreme.

In the entire Weiyang Palace, the ministers' minds suddenly floated, they watched a good show today, from the Feng family's grabbing merit to Merton's counterattack, which can be described as extremely exciting.

The Feng family's move was not without gain, but it was far from as expected, and it was not known whether it was worth offending the Mo family.

The grievances in Feng Zhidai's heart can be imagined, and when he saw Merton, he suddenly had an idea, and said in an unkind tone: "Today is the birthday of the emperor, I don't know what kind of gift Marquis Mo is going to prepare, and let me wait to open my eyes?" ”

Li Yuan and Li Shimin immediately frowned, glanced at Feng Zhidai unkindly, and suddenly disliked it in their hearts.

Merton smiled slightly: "Weichen does have a gift to celebrate the birthday of the Emperor. ”

Feng Zhidai's face suddenly froze.

"Oh!"

Li Yuan was immediately in high spirits, and he was extremely satisfied with the hair dyeing secret technique that Merton had given him before, and he was immediately looking forward to Merton's gift.

Merton took out a palm-sized brocade box from his arms and presented it, Feng Zhidai sneered in his heart when he saw it, even if the brocade box was worth a thousand gold, it was not comparable to the treasure offered by the Feng family.

Li Yuan didn't care, took it and opened the brocade box directly, only to see that in the brocade box, there was a strange transparent thing, which was the reading glasses that Morton had made with great effort.

"This is Shuiyu?"

Li Yuan saw the transparent lenses of reading glasses and said in surprise, he had seen countless treasures in his life, but it was the first time he had seen such a transparent jade, but it was cold to the touch, far less comfortable than warm jade.

"Emperor Hui, this is the latest product of the Mo family, called glass, not jade." Merton explained.

Hearing that it was not jade, Feng Zhidai snorted coldly in his heart, since this is the case, it must not be a valuable thing.

"What is this thing used for?" Li Yuan looked at the reading glasses in his hand puzzled, and couldn't figure out how to use such a strange thing.

Li Shimin's heart on the side moved, as long as it was something newly developed by the Mo family, it would definitely have a strange use, and if Mo Dun could present it as a birthday gift for Li Yuan, it would definitely be extraordinary, and he couldn't help but look forward to it.

"The Emperor Taishang put it in front of him, and you can see it at a glance." Merton sold Guanzi and handed over the latest issue of the ink magazine.

"Huh!" Li Yuan looked down and suddenly exclaimed in surprise.

He did as he was told, and put his eyes on the bridge of his nose without a teacher, only to find that the original blurry font on the original ink journal was extremely clear.

"There's something wrong with the Emperor!" Suddenly, the Manchu Dynasty Wenwu suddenly exclaimed.

Li Yuan shook his head and said with a shocked face: "The old man usually has very presbyopia, and it is very difficult to read ink magazines, but wearing this thing is extremely clear. ”

Since he got older, he has been plagued by presbyopia, who would have thought that when he was nearly seventy, he would still be like a teenager, reading and reading without any obstacles.

"What? Can this thing cure presbyopia? In the Weiyang Palace, the ministers were shocked when they heard this, Li Yuan had presbyopia, which everyone knew. , Looking at Merton's eyes suddenly became hot, and he was able to climb to the position of the courtiers, I am afraid that most of them are already fifty years old, and the older Gao Shilian and Xiao Yu are nearly sixty years old. Old eyes dizziness can be said to be extremely common, usually reading political affairs, extremely difficult, if there is this reading glasses as an auxiliary, I am afraid everything will be solved.

Merton nodded and said: "This thing is called reading glasses, which is specially designed to treat the elderly with presbyopia, which can restore the eyesight of the elderly to the general of a teenager. ”

"Good, good! In the past ten years, I have been a dizzy and dizzy general, and it is extremely inconvenient on weekdays, so I didn't expect to solve it today. Li Yuan said excitedly, among all the birthday gifts, I am afraid that the one that Moton is the most satisfying to him.

When Feng Zhidai heard this, his face suddenly froze, who would have thought that Merton would be such a strange thing, and he would make the emperor happy.

Li Shimin looked at Li Yuan, who was directly wearing reading glasses and couldn't put it down, and glanced at Merton with satisfaction, Merton was able to think so thoughtfully for Li Yuan, which was more gratifying than giving him a gift.

"So, the Mo family has solved the cause of presbyopia?" Li Shimin asked in a deep voice.

Merton nodded and said, "Actually, presbyopia is not a disease, but a symptom that will inevitably appear in people's eyes as they get older. ”

"Bound to happen?" Li Shimin suddenly frowned and said, in this way, one day, he will also have presbyopia, so he will use this reading glasses.

"Yes, sooner or later, it will appear sooner or later, I don't know if Your Majesty still remembers, at the beginning of the year, the secret technique of the Mo family displayed by Weichen at the Mo Family Secret Skills Exhibition, small hole imaging." Morton said in a deep voice.

"Aperture imaging?" Li Shimin suddenly had an idea and said: "Could it be that Mozi's small hole is imaging, just like a human eye?" ”

Aperture imaging can reflect the image of the outside world into the aperture, just as the human eye can see the image outside.

"No, the image of the small hole is an inverted image, while what the human eye sees is an upright image." Li Yuan shook his head and said. He has been very bored recently, but the Mo family's ink skills are very interesting, and he has a very good appetite, and he knows almost everything about the secret skills of the Mo family.

Merton shook his head and said, "Although the truth is the same, the human eye is a step more complicated than the image of a small hole, when the small hole is imaged, the round hole is a plane, but our eye is a convex surface. ”

When everyone heard this, they couldn't help but touch their eyes, and sure enough, they were convex.

"So on the basis of the small hole imaging, the kid made further eyes for this phenomenon, and made the mirror convex, as if there was a pair of eyes outside the eyes, so as to help the elderly recover their eyesight." Merton explained.

Everyone was suddenly amazed and couldn't help but secretly admire. I'm afraid that this secret technique can only be done by the Mo family, just ask, who in this world knows the mystery of light and shadow better than the Mo family.

Li Shimin also sighed, who would have thought that in the secret technique of the Mo family, the seemingly useless small hole imaging would actually promote the birth of reading glasses and solve the problems of the old people in the world.

"Can this be mass-produced?" Li Shimin asked, you must know that Li Yuan is not the only one in the world who suffers from presbyopia.

In an instant, Merton suddenly became the focus of the audience, you must know that in the main hall, many important ministers are old.

Merton nodded and said: "This glass is not the first of the Mo family, in the country of the extreme west, it must have a history of thousands of years. ”

After Merton finished speaking, he deliberately glanced at Feng Zhidai on the side, which immediately made Feng Zhidai sit still.

Merchants from the Western Regions brought a steady stream of secret techniques and seeds from the Silk Road that the Tang Dynasty did not have, and the contribution to nature is self-evident, and the glass in front of them is the best example.

"Although the production is not high, it is enough to supply the demand for reading glasses." Merton said with a confident smile.

The important ministers of the Manchu Dynasty suddenly showed a satisfied look, as long as they were not the only eyes in the world, they were naturally indispensable.

"Over time, the output of Mojia Village will increase, and this thing will definitely be like an ordinary thing, and everyone in the world will have a pair of hands." Merton said again.

"Good! It seems that this thing is not a birthday gift for me alone, but a common birthday gift for the old people in the world, and I am ashamed of this filial piety for the old people in the world. Li Yuan said proudly.

The Tang Dynasty governs the country with filial piety, and no matter how much Confucianism attaches great importance to filial piety, Li Yuan's evaluation can be said to be extremely honorable, but everyone has no objections, after all, Merton should evaluate this, only Feng Zhidai bowed his head unwillingly.

The result is very obvious, among all the birthday gifts, Merton's reading glasses are the best, and they are the most popular with Li Yuan, for the royal afterlife, how can those gold, silver, jewelry, and rare objects be put in their eyes.

The Feng family tried in vain to cut off Hu Johor rice to show their loyalty, but instead of succeeding, they stole chickens and rice, and Mo Jiazi's pair of reading glasses benefited the emperor and the common people, and the results are self-evident.
