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

"Observe the stars, watch the sun, and predict the weather! What a talent!" Zou Yu then remembered that this can be used in military affairs, and in the future, people who understand star maps will be needed to guide navigation!

The more he looked at them, the more satisfied he became, just like a weasel looking at a chicken. Zou Yu smiled happily and said, "Okay, everyone, just stay, have a light meal, and watch the moon together in the evening!"

Although Zou Yu was heartbroken by this sight, the three of them quickly thanked him and stayed.

"The Prime Minister's home is really unique!" Zhiyuan sighed after relaxing and scanning the decorations in Zou Yu's study.

"Yes, it is simple and comfortable. This kind of table and chair is much more comfortable than sitting on your knees or on a bench." Yuan Tiangang sighed.

There were many visits to the Yuan Tiangang family's wealthy family. Relatively speaking, Zou Yu's palace was the simplest, with no antiques, gold or silver utensils.

In Zou Yu's study, there are many calligraphy and paintings hanging, such as the preface to Orchid Pavilion and the pictures of Luo Shen Fu! But Yuan Tiangang and others can see that these were copied by recent people.

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

Another reason for this is that the calligraphy and paintings of Brother Yan Lide are so beautiful that even Zou Yu, who does not know how to appreciate them, finds them pleasing to the eye, so he had them framed and hung in the study.

Of course? This kind of behavior moved the Yan Lide brothers. They felt that Zou Yu valued them. He had a kind of mentality of working hard to die. It turned into motivation all year round. Almost all of them worked as craftsmen's supervisors or in workshops, leading

People frantically studied the views and demands put forward by Zou Yu.

"The Prime Minister's glazed mirror? Everyone in the world knows it? Everyone knows that how many people want to buy one at a high price but cannot get it. They never thought that the Prime Minister is so frugal." Yuan Tiangang praised repeatedly.

Zou Yu usually wears a tight-fitting samurai suit unless he is in a formal meeting? Because it is more convenient to move around? As for the fabric, it is ordinary silk, which is why Yuan Tiangang and others lamented it.

"Glazed mirrors, we call them glass mirrors, are not precious. Court officials? Most of them have one or two in their homes. When the technology matures in the future, it will not be difficult for everyone to have one!" Zou Yu waved his hand and said.

"The Prime Minister is asking people who know how to make alchemy to come and study this thing?" Li Chunfeng asked.

"Is this just one of them? As far as I know, alchemy uses many strange ores? Naturally, the things that come out are all kinds of different? But they don't pay attention to these. What they want to study is every mineral? What they can do

The effect produced." Zou Yu replied.

"Yeah, but most of those things are waste materials and toxic." Yuan Tiangang nodded slightly.

"That's right! Ore is toxic when it enters the human body, and even some air contains deadly things. However, the uses are also very huge, so people need to study it."

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

"Good question! This kind of mirror does have a magnifying effect, but the harmful substances in the air cannot be found yet." Unexpectedly, Li Chunfeng came up with some uses so quickly, Zou Yu was stunned and replied.

"Oh." Li Chunfeng nodded slightly disappointedly.

"Although it is not visible yet, it does not mean that it will not be visible in the future. You will need to study it in the future! But now, we can take a look at the things in the water." The topic changed and Zou Yu continued.

"Things in the water?" The three of them looked at Zou Yu with interest.

A simple microscope was made by the skillful hands of the craftsman. Although it cannot observe cells, it can still barely see bacteria and insects in the water.

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

A microscope over fifty centimeters high is as bright as gold under candlelight. Use a small wooden stick to dip a drop of water in a bowl, drop it on the glass, and then put the glass under the microscope.

He adjusted it gently and observed it for a moment, then stepped aside and motioned to Yuan Tiangang and the others to take a 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.

"It is said in the classics that you can see the world in your sleeves and see the world in your palms! Isn't that the case?" Zhiyuan said thoughtfully.

"Buddhists also say that there is one flower and one world, and one leaf and one bodhi. It turns out that this is true. Such tiny insects are invisible to the naked eye, but they exist. If you think about these little creatures in the water, there should be countless!" Yuan Tiangang sighed.

"Could this kind of bug be a result of hostility? It's because the hostility in the human body is too strong, so it makes you sick?" Li Chunfeng guessed.

"Yes, diseases enter through the mouth! Many times, people get sick because there are too many bugs and impurities in the food they eat." Zou Yu nodded and said.

"No wonder there are roundworms in the human body. I don't know where they come from. They should come from the water!" Yuan Tiangang guessed.

"Relatively speaking, bugs in water are not harmful. There are more bugs in meat. However, whether it is water or food, they will be killed after cooking." Zou Yu explained.

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

"If Taoist Master Sun were here, he would definitely like this very much..." Yuan Tiangang pointed at the microscope and said.

"Microscope, this is the first generation of microscope, and it is also waiting for improvement!" Zou Yu said.

"Microscope! A mirror that reveals the subtleties! The Prime Minister gets a good name!" Yuan Tiangang agreed.

"It's getting late. Let's eat first. After dinner, we can watch the moon!" Zou Yu said with a smile when he saw that it was getting late.

"Okay! Watch the moon after dinner!" Li Chunfeng said impatiently.

Originally, a few people wanted to eat quickly and eat while watching the moon, but they didn't know that the stir-fried vegetables were so delicious. Even though Zhiyuan and Yuan Tiangang had been cultivating their minds for many years, their skills were broken and they ate a lot.

"The Prime Minister is laughing!" The elder said with a blush as he put down his chopsticks.

"It's okay, it's okay, as long as you don't mind having a simple meal."

"Where! Where! In the prime minister's house, even the vegetables have a unique flavor. This meal is the most delicious meal Pindao has had in so many years." Zhiyuan shook his head and sighed.
