Five pine chairs, two coarse teas.

In the west wing, the majestic old man put down the teacup and looked at the young man in front of him.

"Qin Xianao's divine book, it's good that you can meet the requirements so quickly. Sima Guang nodded slightly, "The content of the Divine Book is the Longevity Formula, I hope it will be useful, but this is unlikely, so don't get your hopes up too much." ”

"Master, I have always had no hope, the hard work and luck required by the recipe for longevity, as well as wisdom, I am familiar with the algorithm, but I just make the calculation a little faster. Chen Qian said with a smile.

Sima Guang's jaw: "It's like going to Lingnan, walking, horseback, and boating, but there is speed and slowness, but what determines whether you can get to Lingnan is whether you are on the right road, well......"

"Master, Mr. Yichuan asked someone to send a gift. ”

The door was pushed open, and I saw the old man walking in with a cylinder on his head and a newspaper in his hand.

"......Gifts? Telescope?" Sima Guang's eyes lit up immediately, and Sima Guang also made a telescope, but Cheng Yi specially sent it, it couldn't be very bad.

"I don't know if it's a telescope or not, but here's a note from Mr. Ikawa. Lao Chongtou put down the cylinder, took out a letter from under the newspaper and handed it to Sima Guang. Sima Guang connected and opened, and there was a thin piece of paper inside.

"Recently, I was invited by Qin Xianao to go to Lingnan, and I felt a lot, Qin Gongzi has a new telescope experiment, and there are fifteen remnants, I asked for it, one of them, and I gave it to Junshi. ”

Sima Guang looked at the short note in his hand in a daze, Qin Xianao's defective product, you want to come back and give it away?

"Master, this thing is set up!" the old man's voice sounded.

Sima Guang smiled bitterly and shook his head, originally thought that Cheng Yi would give a better telescope, a little better than his own, but they just asked Qin Xianao's cripples back. How good would it be?

"Well, let's see how bad it has become. ”

Sima Guang walked out of the house, came to the high platform, and looked at the set up telescope, and his eyes lit up.

The three golden characters of 'Chongzheng Building' appeared in the line of sight, and the words were so clear that even the texture was visible.

"This ......"

Sima Guang looked away. Look at the tall building in the distance.

"I actually saw ...... through the telescope" Sima Guang glared, took a breath, and moved his gaze to the telescope again, and then the whole person was stunned.

"Really, it's really 'Chongzheng Building', and Chongzheng Building is almost ...... away from here This...... Is this a defective product?" Sima Guang looked at the plaque in the camera in a daze, and only after a while did he start to move the camera, observing the tall buildings and plaques in the distance. His eyes were getting brighter and brighter, and after a long time, he put down his binoculars.

"This Uncle Zheng, it's really ......" Sima Guang shook his head, "If this is a defective product, then wouldn't no one want my one to throw in the garbage heap?" Sima Guang was amused and weird in his heart.

"Master, this telescope?" asked Chen Qiang.

"Good, good. It's never been better, you know it when you see it. Sima Guang's face was full of red. looked at the newspaper in the hand of the old head on the side, "This is the new issue of "New Youth"!"

"That's right, master, according to the newspaper boy, this issue has Qin Xianao's article. ”

"Which issue of "New Youth" does not have Qin Xianao's article. Sima Guang took the newspaper with a smile and flipped it open, and then his expression became solemn.

"Supplementary Matters on 'All Things Have Quality'!"

This is Qin Xianao's article.

"When Ah Zhu and Ah Bi interviewed me, I mentioned that Mr. Yi Chuan's "Everything Has Quality" is theoretically perfect. But it is not enough to put it in the textbook, because there is a lack of standards...... "Sima Guang continued to read, and gradually his eyes became brighter and brighter.

"Put mercury in a U-shaped tube, vacuum at one end, and pressure pressure at the other end will press on the other end......"

I read Cheng Yi's "All Things Have Quality". Knowing the knowledge of pressure, atmospheric pressure, etc., and reading the principle of barometer production described in the Qin Dynasty, Sima Guang naturally understood it as soon as he read it.

"It's really the best way to measure air pressure, but it's just ...... What is this tube for?" Sima Guang looked down suspiciously.

"The difficulty of this method is to observe the height of the mercury column, so the container for the mercury must be a transparent substance like crystal, but crystals have always been precious, and even if there are enough crystals for people to waste, the process required to make a barometer is a great problem......

Sima Guang nodded slightly, it is not easy to polish the crystal concave and convex mirror, let alone make it like a barometer.

"I have a sense of glass, made of glass, and it can also be colorless and transparent......"

Sima Guang's eyes widened, made of glass, colorless transparent glass?

Sima Guang became interested.

"This glass, also known as colorless glass, is best suited for making a variety of observation tools, and of course for atmospheric pressure. "The Qin Dynasty just passed by a simple sentence, and then-

"I made a barometer and invited Mr. Ikawa to go south ......"

......

One by one, the scholars read this 'Addendum', and many of them were extremely interested in the 'glass' that Qin Xianao talked about, but Qin Xianao didn't say much in the article at all. In addition to glass, the most emotional, and even jealous thing in the article is that after Qin Xianao made a barometer, he actually invited Cheng Yi to go south to determine the standard.

"Qin Xianao didn't even pay attention to Confucius, but this time he ......" Sima Guang put down the newspaper and narrowed his eyes.

"Either Qin Xianao is putting on a show, or Qin Xianao respects 'cheap learning' from the bottom of his heart. Lu Gongzhu sighed slightly, his eyes were full of envy, "Qin Xian is proud of his standards, and he actually named it after Uncle Zheng, a standard atmospheric pressure is called 'Yi', this trick is very poisonous!"

In later generations, in order to commemorate the outstanding contributions of physicists, it is normal to name the unit of voltage with 'volts', 'ohms' for resistance, and 'Newton' for the magnitude of force.

The Qin Dynasty used the name 'Cheng Yi' to name a unit of standard atmospheric pressure, which was the first time in the world.

And the benefits that come with this.

Many scholars do not seek wealth or power, but seek a name, which even Sima Guang, Wang Anshi, and Cheng Yi, who are flawless in moral cultivation, can't escape the word name in their hearts.

The natural phenomena that will be discovered, named after the person who discovered them, can be imagined. Even if Cheng Yi is nothing, this alone can make him famous for a hundred years, such benefits ordinary people don't feel, but who in the academic world doesn't envy them.

"Obviously, it can be named something else, Qin Xianao invented the barometer, and he will determine the pressure unit. You can use your own name, but ......"

"Cheng Yi invented pressure, and named the standard pressure unit after him, it is indeed reasonable, but Qin Xianao can do it without leakage, and he also invited Cheng Yi to discuss and determine the standard air pressure and pressure formula......"

"Qin Xianao really wants to straighten out the 'cheap learning'. That's why I work so hard!"

......

In a courtyard of Lizheng Academy, Luo Congyan put down the newspaper with a smile: "It turns out that the pressure unit is 760 mm Hg, this millimeter is the unit of Lingnan, and a pressure unit is called 'Yi', which is the name of the ancestor, I will say how the teacher can go to Lingnan, and his mouth is suddenly a lot more polite to Qin Xianao, and the benefits are here." ”

To say that there is no envy is false.

"Still. My priority now is to pick the fruit!" Luo Congyan walked to the table and sharpened the ink. I thought about it naturally in my mind, and quickly sharpened the ink, and naturally Luo Congyan picked up the brush and wrote.

"Huh?"

Not far away, several scholars glanced at each other.

"Didn't Senior Brother Luo say that after reading the newspaper, he began to pick fruits from the point of view in the ancestor's "All Things Have Quality", what's the matter?"

"Picking the fruit has always been a very difficult task, and when you pick the fruit, you don't have to think about it for days. Dozens of days? And intermittently, where can there be a saying that picking fruit can be written with a pen?"

"Still writing so smoothly, with a smile on the corner of your mouth?" they shook their heads one by one, and they all knew in their hearts. Big brother must be writing something else.

One by one, the formulas of longevity poured out from Luo Congyan's pen like water.

Because the difficulty is too high and the frustration is too great, it is often extremely painful under normal circumstances.

But this time.

A kind of pleasure, thoughts like flying, writing like a god, the kind of handy, like playing a game everything in the chest, easy and easy, even if you occasionally stop thinking about it, you can quickly find the next way to operate.

Time passes.

After Luo Congyan began to pick fruits, Qin Wanqing also completed the task of the divine book, and then two or three more were completed, and it was 40 days in the blink of an eye.

In a courtyard to the west of Lizheng Academy, two scholars looked strangely at Luo Congyan, who was flying like a pen in the house.

"It's strange, Senior Brother Luo obviously said that he was the recipe for longevity, but for more than a month, he didn't know what he was writing?"

"Yes, Hechangsheng Jue has always been bumpy, there has never been such a thing, he must be writing something else, and even I suspect that he didn't do anything, just practicing calligraphy, if he hadn't told us a long time ago that we couldn't bother him, I would have gone into the house to see it. ”

"Senior Brother Luo has a very good temper, you must not enter the house, just deliver food and food as instructed. The two scholars laughed, and the old man in white not far away shook his head, and suddenly the old man's body trembled.

"Vision?"

The old man glanced around, then looked up at the sky, and then his body trembled: "It's a vision, it's a vision of heaven and earth!" The old man rushed out of the house, flew on the roof, and stared at the sky, "This is really a vision of heaven and earth, it seems that there are masters here who are cooperating with the secret of longevity......" The old man was stunned.

"No, there's no one picking fruit here. ”

It's not that no one picks it, Luo Congyan said 40 days ago that he wanted to pick the fruit, and it didn't take long for Qin Wanqing, Wang Jinping and others to complete the task of the divine book, and some of them also began to pick the fruit.

"Picking a fruit, even if it is an extremely easy 'cheap learning', it is difficult to succeed without years, not to mention anything else, no matter which one of my Lizheng Academy protégés, it is impossible to be so fast, who is that?"

After a long time, the old man smiled bitterly: "Forget it, forget it, no matter who it is, in short, let's inform everyone!" He raised his head and let out a long howl, the whistling sound came from afar, Luoyang has always had many congenital masters, although because of the outbreak of fruit picking frenzy in Lingnan, many people went to Lingnan, but the members of the Tai Chi Club no longer pick fruits recently, but entered the Tai Chi class as training teachers, and many of the original Luoyang innate masters naturally returned.

One after another congenital masters gathered at Lizheng Academy.

As time passed, Lizheng Academy had a vision of heaven and earth, and the news of who picked the fruit also spread to all directions. (To be continued.) )
