It rained heavily all night, and except for Zhangjiacun, everywhere else was muddy.
Naturally, someone who loves cleanliness like Zhang San is not planning to go out. The early advertising was very powerful. Those merchants who placed advertisements in newspapers were more attractive than merchants in the same industry, and their sales volume continued to rise. This also made those merchants
Businessmen who have tasted the sweetness are more interested in advertising.
Due to the heavy rain these days, Li Tai did not come to see Zhang San. Zhang San also enjoyed his leisure time. Of course, he did not know that the weekly report of the National Commercial Bank was now popular in Chang'an.
Due to the strong yin and weak yang at home, Zhang San is now "isolated" by them again, so Zhang San is also very bored these days.
So I continued to study my own telescope. I couldn't help much at the medical school. What I knew was of no use now.
Unless you are teaching knowledge like battlefield first aid, you can just find someone from the escort to teach you. Now they are all experts.
Especially Genzi, Zou Rong and the others who followed him to the border.
Zhang San actually wanted to develop a microscope, but his strength did not allow it. After studying it for a long time, he made no progress at all. It was no more than a magnifying glass and could not be used for medical research.
Things like those bacteria cannot be seen at all.
Zhang San is thinking about setting up a scientific research team. He has rich theoretical knowledge, but lacks practical ability.
However, Zhang San also knew about the abilities of these people in Zhangjiacun and had no talent in this area at all.
"Talents are needed in the 21st century, and we need talents even more now!" Zhang San sighed while assembling his small telescope.
"What are you mumbling about?"
At this moment, a voice suddenly came into Zhang San's ears.
As soon as Zhang San heard this voice, he wanted to run away, but he was very surprised as to why Li Shimin ran away from his home without anyone notifying him.
Didn't this catch me off guard? Fortunately, I didn't say anything bad about Li Shimin just now, otherwise I would have stopped eating.
Since it was cloudy today, it was windy outside and relatively cool, so Zhang San tinkered with his telescope in the yard.
Now that Li Shimin had arrived, Zhang San had no choice but to put down his work and quickly stood up and walked forward to salute: "I have seen the emperor, and I said that the magpie was standing on the tree of my house early this morning and kept screaming. It turned out to be the emperor."
It’s so exciting to come…”
Hearing that Zhang San was obviously flattering again, Li Shimin interrupted angrily: "Okay, if you don't know how to flatter, don't imitate other people's flattery. It sounds awkward. What are you doing?"
Li Shimin felt like he was at home wherever he went, talking and doing things by himself.
I saw this tube-shaped thing with two holes at both ends, which were blocked with transparent glass.
After continuous improvement and technical processing by Zhang Ergou and others, colorless glass was finally developed. Of course, it is not completely colorless and transparent, and there are still some bubbles in it.
Li Shimin was very curious when he saw the thing in his hand, and then he put his eyes to a hole in the bamboo tube, "What the hell?"
Li Shimin was startled when he saw a big eye. He threw the bamboo tube in his hand and hit the big-eyed monster in the face.
Xu Huang was innocently hit in the face by the bamboo tube thrown by Li Shimin, but Xu Huang did not dare to dodge and did not even blink.
"Why is it you? I saw a big-eyed monster just now?" Li Shimin was very confused when he saw that he had hit Xu Huang's face.
Zhang San stood aside and wanted to laugh but did not dare to laugh. He was feeling very uncomfortable.
Li Shimin saw Zhang Sanqiang holding back his smile and knew that he had been embarrassed just now.
But who was Li Shimin? He quickly changed his target.
"Just laugh if you want, Zhang Xianhou. Don't hold it in. I just remembered that the thirty-big board was a little too light last time. How about we start over?"
Hearing Li Shimin's obviously threatening tone, Zhang San quickly said seriously: "No, I was in bed for half a month last time!"
As for the specific number of days he lay in bed, Zhang San couldn't remember clearly, but it only lasted a week, but it was better to tell more at this time.
Li Shimin picked up the bamboo tube again. This time Zhang Sanxue was smarter and quickly explained: "Your Majesty, this is a telescope invented by me. It can see very far away. Of course, if the distance is too close, like just now, Your Majesty, you looked at Xu at close range."
Father-in-law's face will be magnified infinitely..."
After listening to Zhang San's explanation, Li Shimin looked at the telescope in his hand again.
"Is this thing so magical?" After Li Shimin finished speaking, he placed the bamboo tube in front of his eyes again. This time he looked at the sky. There happened to be a group of birds flying through the sky. When they passed Li Shimin's sight, they were instantly magnified countless times.
Almost like a big goose.
Li Shimin used his binoculars to chase the birds and did not stop until they were out of his sight.
"Your Majesty, come with me. Let's stand on the platform on the roof and see better." Zhang San said when he saw that Li Shimin liked the telescope very much.
At this moment, Fang Keying and Mrs. Xu knew that Li Shimin was coming and hurriedly came out to see him.
Li Shimin exchanged a few words with the two of them and then impatiently followed Zhang San to the roof.
Of course, this time Zhang San finally understood why Li Shimin liked to take the old eunuch Xu Huang with him wherever he went.
Just because he wanted to use the ladder to climb up, he stood aside to hold the ladder for Li Shimin.
Unexpectedly, he didn't need it at all, and even glanced at me with very contemptuous eyes.
Then Zhang San saw Xu Huang flying directly to the roof with Li Shimin's arm.
"Why are you still standing there? Climb up quickly." After Li Shimin climbed up, he saw Zhang San's big mouth and shouted proudly.
Zhang San came back to his senses and was shocked, "Damn! This is a master! It turns out there really is such a thing as Qing Gong!"
Naturally, Xu Huang would not fly down to give him a try, so Zhang San had no choice but to climb up the ladder obediently.
"Eunuch Xu, master, is this Qing Gong? Can you teach me?" Zhang San said to Xu Huang quickly after he came up.
Xu Huang just smiled and said nothing. After Li Shimin got on the platform, he saw a larger telescope set up on it.
"Why are you keeping such a big telescope here?" Li Shimin asked.
Seeing that Xu Huang ignored him, Zhang San touched his nose, but he made up his mind that he must find such a master to become his apprentice.
"Back to the emperor, this is an astronomical telescope developed by me. It is used to see the stars." Zhang San explained.
"Look at the stars?" Li Shimin looked up, then looked at Zhang San, as if to say, are you kidding me?
Are you watching the stars here on this cloudy day?
Zhang San can’t say that Li Shimin has never seen the world, but he certainly can’t see the sky. Zhang San is put here just to see the scenery.
The Qinling Mountains in the distance have been cleansed by a heavy rain, and the water vapor permeates the mountains. From a distance, it looks fairy-like and beautiful.
