"Today, the moon is bright and the stars are scarce, and there are no clouds!" Yuan Tiangang glanced at the sky outside the room and said confidently.

"Stargazing, sun, weather prediction! Talent! Zou Yu then remembered that this can be used in the military, and in the future, when sailing, people who understand the star map are needed to guide the direction!

The more you look at a few people, the more satisfied they are, just like a weasel seeing a chicken, Zou Yu smiled happily and said: "Okay, you can stay, have a light meal, and enjoy the moon together at night!" ”

Although Zou Yu was furious, the three of them hurriedly thanked them and stayed.

"The prime minister's family is really ingenious!" Relaxing and scanning the ornaments in Zou Yu's study, Zhiyuan sighed.

"Yes, simple and comfortable, this kind of table and chair is much more comfortable than kneeling and stooling." Yuan Tiangang sighed.

Yuan Tiangang's family did not go to the family, relatively speaking, Zou Yu's palace is the most simple, and there are no antiques, gold and silver utensils.

Zou Yu's study has hung a lot of calligraphy, calligraphy and paintings, like the Orchid Pavilion Preface, Luo Shen Futu! These. But Yuan Tiangang and others can see that this is the most recent person who copied it.

Zou Yu will definitely not tell them that this is the work of Yan Lide, Yan Liben's brother, although the value is not high now, it may not be much worse than the original in the future.

There is another reason for this, that is, the calligraphy and paintings of the Yan Lide brothers are very beautiful, even Zou Yu, who does not know how to appreciate them, also feels pleasing to the eye, which makes people frame and hang them in the study.

Of course, this kind of behavior moved the Yan Lide brothers, and they felt that this was Zou Yu's attention to them, and they had a kind of mind of doing their best and dying, and turned it into motivation that almost all year round, they were in the craftsman supervisor or workshop, leading people to frantically study the views and requirements put forward by Zou Yu.

"The prime minister's glass mirror, everyone in the world knows, no one knows, how many people want to ask for a side at a high price but can't, I can't imagine that the prime minister is so thrifty." Yuan Tiangang praised again and again.

As long as Zou Yu is not in a formal meeting, he is generally a tight-fitting samurai uniform, because it is more convenient to move, and as for the fabric, it is ordinary silk, so there is a sigh of Yuan Tiangang and others.

"The glass mirror, we call it a glass mirror, is not precious, and the court officials have one or two sides in their homes. When the technology matures in the future, it is not difficult to have one hand! Zou Yu waved his hand and said.

"The prime minister is to let people who understand alchemy come to study this thing?" Li Chunfeng asked.

"This is just one of them, as far as I know, alchemy will use a lot of strange ores, and the things that are refined are naturally varied, but they don't pay attention to these. What they're looking at is what each mineral can do. Zou Yu replied.

"Well, but most of those things are scrap and toxic." Yuan Tiangang nodded slightly.

"Not bad! When ore enters the human body, it is poisonous, and even if it is just some air, it contains something deadly. However, the use is also very huge, so it needs to be studied. ”

"Can this telescope see the poisonous stuff in the air?" Li Chunfeng asked suddenly.

"That's a good question! This kind of mirror does have a magnifying effect, but those harmful substances in the air cannot be found at present. I didn't expect Li Chunfeng to be so fast, so he thought of some uses, Zou Yu was stunned for a moment and replied.

"Oh." Li Chunfeng nodded slightly disappointed.

"Although I can't see it now, it doesn't mean that I won't be able to see it in the future, which needs you to study it in the future! But now, we can look at what's in the water. As soon as the conversation changed, Zou Yu continued.

"What's in the water?" The three of them looked at Zou Yu with great interest.

A simple microscope, made by the skillful hands of the craftsman, although it is not yet possible to observe the cells, but it is barely possible to look at the bacteria and insects in the water.

took the three of them to the corner of the study, lit a few candles around to illuminate the light in the room, and then asked Xi Jun to buy and fill a bowl of dirty water.

A microscope more than 50 centimeters high, like gold in the candlelight, is so bright. Using a small wooden stick, dip a drop of water in a bowl and drop it on top of the glass, then place the glass under the microscope.

Gently debugged and observed for a while, then let go and motioned to Yuan Tiangang and the three of them to look.

According to Zou Yu's appearance, the three of them took turns to look at it for a while, and then stood aside thoughtfully.

"In the classics, it is said that you can see the world in the palm of your hand! Isn't that what it is? Zhiyuan said thoughtfully.

"Buddhism also has a saying that one flower is one world, one leaf is one Bodhi, and it turns out that there is such a thing. Such tiny insects, invisible to the naked eye, exist anyway, and there should be countless such small lives in the water! Yuan Tiangang sighed.

"This kind of worm, could it be that it is angry, because the human body is too angry, so it is sick?" Li Chunfeng guessed.

"Yes, the disease comes from the mouth! Many times people get sick because of what they eat, these bugs, and too many impurities. Zou Yu nodded and said.

"No wonder there are roundworms in people's bodies, and Poor Dao has never known where they came from, it should come from the water!" Yuan Tiangang guessed.

"Bugs in the water, relatively speaking, are not very harmful, and there are more in meat, but whether it is water or food, after cooking, they are killed." Zou Yu explained.

Of course, he didn't say that high temperature only kills most bacteria, and there are still people who are not afraid of high temperatures. He couldn't explain it clearly, not to mention that after the high temperature, the food was safe, and there was no need to say it.

"If Sun Daochang is here, he will definitely like this..."Yuan Tiangang pointed to the microscope and said.

"The microscope, this is the first generation of microscopes, and it is also waiting for someone to improve!" Zou Yu said.

"Microscope! A mirror of subtlety! The prime minister gets a good name! Yuan Tiangang agreed.

"It's not early, let's eat first, and it's time to watch the moon after eating!" It's not too early to see that it's dark, Zou Yu said with a smile.

"Good! After eating, watch the moon! Li Chunfeng couldn't wait.

Originally, a few people wanted to eat quickly, and after eating to see the moon, how did they know that the stir-fried dishes were so delicious, even if Zhiyuan and Yuan Tiangang had cultivated their hearts for many years, they were also broken and ate a lot.

"The prime minister smiled!" Putting down the chopsticks, the elder blushed and said.

"It's okay, it's okay, you don't think it's coarse tea and light rice."

"Where! Where! In the Prime Minister's Mansion, even if it is just green vegetables, it has a unique flavor, and this meal is the most delicious meal in Poor Dao for so many years. Zhi Yuan shook his head and sighed.

"It is said that you don't get tired of eating, and you don't get tired of being fine! After eating a meal in the Prime Minister's mansion, Poor Dao must not know the taste of meat for several months. Yuan Tiangang laughed.
