"Nope! I don't want alchemy! I just want a group of people who love this way to help the court study something. Zou Yu waved his hand and said.

"Prime Minister, as soon as Cheng Immortal said, after all, it is ethereal, and Emperor Qin and Han Wu have never been immortal!" Yuan Tiangang frowned, and then persuaded with a tangled face.

Looking at Yuan Tiangang's appearance, Zou Yu was secretly grateful, and felt funny. A Taoist master, just from his mouth, Cheng Immortal asked, ethereal words. But for his concern, I am quite grateful.

"Dao Chief, you're too worried, I really don't want to live forever! Many of the things that alchemists refine are very useful, but they don't know the way. And their spirit of pursuing answers is what I need. Zou Yu smiled and said with relief.

"So be it! Daoist, look at this! Zou Yu took a copper stick of different sizes at both ends and the thickness of an adult's wrist from the shelf on the side of the study, handed it to Yuan Tiangang and said.

Yuan Tiangang stretched out his hands and held them hard, feeling very light, only to find that the copper rod was hollow, and it should be called a copper pipe.

The appearance of the copper pipe is smooth and there is no pattern, Yuan Tiangang looked at the middle of the copper pipe and found that it was actually inlaid with glass in two sections.

"What is this?" Yuan Tiangang looked at Zou Yu suspiciously and asked.

"You put this in front of your eyes, and then look inside." Zou Yu smiled slightly, helped lift the copper pipe, and explained to him.

Yuan Tiangang followed Zou Yu's explanation, put the copper pipe in front of his right eye, and looked into the copper pipe.

As soon as he put his eyes in front of the copper pipe, Yuan Tiangang was so frightened that he raised his head back violently, and then his eyes blinked quickly, waited for a while, and put his eyes on the copper pipe again.

This time, Yuan Tiangang was not frightened again, but looked around with great interest, and kept saying: "Wonderful! It's wonderful! ”

"Brother Dao! Brother Dao! Seeing that Yuan Tiangang was strange, holding a copper pipe with a long neck, it was very strange like that, and the elder Dao felt a little embarrassed, and couldn't help but gently pull his sleeve and shouted.

"Prime Minister, isn't this the legendary clairvoyant?" Yuan Tiangang didn't have a chance to reach Yuan, but asked excitedly.

"What!"

"Clairvoyance!" Before Zou Yu could answer, Zhi Yuan and Li Chunfeng exclaimed.

"I can't see that far, dozens of miles at most! If you go any further, it's blurred! Zou Yu waved his hand and said.

Of course, this copper tube is a telescope, but this is the first generation of telescopes, but because of the firing of glass, it depends on luck, and there are impurities and bubbles if you are unlucky, so the first generation of monoculars, this size lens is a little too large, the proportion is not coordinated, and the influence of transparency, so Zou Yu thinks it is very general, but it has commemorative significance.

"Can you show Lao Dao?" Zhiyuan asked expectantly.

"Absolutely!" Zou Yu handed him the binoculars again, and from the door of his study, he looked into the distance, and there happened to be a mountain faintly.

"Tsk! Gee! That mountain is thirty miles away! It's so clear! With Yuan Tiangang's demonstration, Zhiyuan directly put the telescope in front of him, and couldn't wait to stretch his neck to look around.

Seeing their fuss, Xi Junmai disdainfully pursed his mouth, and completely forgot that he had been watching it for a long time before he reluctantly put it down!

"Master! Show me! Li Chunfeng anxiously waited for Zhiyuan to watch, and finally waited for him to put it down, and immediately rushed over and said.

Zou Yu knew that they would have to watch for a while, smiled slightly, stretched out his hand to Yuan Tiangang, and invited him to sit down and talk.

"Good tea!" Yuan Tiangang sat down, picked up the cup, saluted Zou Yu as he raised the tea bowl, smiled and took a sip, and the tea was still warm, and he admired it.

"Hehe, it's just a cup of tea, and the Taoist has won the award!" Zou Yu picked up the lid of the tea bowl with his right hand, gently brushed the tea leaves twice, then drank two sips, put down the tea bowl and said with a smile.

Drinking tea, of course, is a bowl of tea, which not only has a sense of ceremony, but also has a lid, and the tea can be kept warm even if you don't drink it immediately, and there is a lid, which makes it easier to brew the taste of the tea and will not dissipate.

"Poor Dao, this is not nonsense, this kind of tea, many Taoist friends are also drinking, although it looks light, but it has a different flavor! Prime Minister, your tea is not so bitter, and the aftertaste is even sweeter! Yuan Tiangang shook his head and sighed.

"Hehe, what the Taoist chief said, it should be the tea leaves that are directly picked and dried! And my tea leaves, with a few more processes, so the taste is slightly better, and it is stored for a longer time, even if it is stored for a few years, the taste will not change. Zou Yu introduced with a slightly smug smile.

Tea making, he just remembers such an introduction, which can be said to be crossing the river by feeling the stones, successfully made, and praised by everyone, which is of course happy.

Li Chunfeng reluctantly put down the binoculars and kept looking at Xi Junmai intently, until the telescope was put on the shelf, and then he looked away with difficulty.

"I call this a telescope! The key is the glass inside, which is fired by the craftsmen of the craftsman's supervisor. It's just that the craftsmen and supervisors are so busy that I want to ask a group of Taoist masters to help study these things. Zou Yu explained with a smile.

"Give me a telescope, and I'll help the prime minister research!" Li Chunfeng stood up and said.

"Sit down!" Zhi Yuan glared at him and shouted. Then he apologized to Zou Yu and said: "The little apprentice is rude, please Prime Minister Haihan, the main reason is that he is obsessed with stargazing and celestial phenomena, so he is so out of shape." ”

"This can't be used for stargazing!" It turned out that he wanted to see the stars, Zou Yu shook his head and said.

"Would you like to see what's on the moon?" Seeing Li Chunfeng's dejected appearance, Zou Yu smiled mysteriously and said.

likes to look at the stars, this hobby is good, it seems to remember that Li Chunfeng is an astronomer, Zou Yu began to think about keeping him in his heart.

Although for the mysterious space, even in later generations, the understanding is very, very limited, but someone has to take this road, if one or two thousand years in advance, someone to systematically study and explore, this will undoubtedly make a great contribution to future generations, so that future generations can have fewer detours and more accumulation.

"Prime Minister, do you have a telescope that can see the moon clearly?" Li Chunfeng stood up again, his nostrils were full of air, his eyes widened, and he looked at Zou Yu expectantly and asked.

Of course, Zou Yu would not let him down, nodded with a slight smile and said, "Yes!" ”

After thinking about the date for a while, Zou Yu continued: "You have come at the right time, tonight is the sixteenth, if there are no clouds, it is a good opportunity to see the moon!" ”

Like the first ruthless man at the end of the Sui Dynasty, the first ruthless person at the end of the Sui Dynasty.
