night.
After eating, Li Zexuan went out and walked towards Yanhuang Academy.
Lan'er, the little tail, naturally followed.
It is said that during the time when Han Xiaoyun's son Mei Zhihuan was in the Li family, Lan'er found a new playmate. Finally, there was someone younger than herself in the family. This girl naturally acted as the elder. Sister, many times the way you pretend to be an adult always makes others laugh.
However, Mei Zhihuan's condition had recovered as early as the day before yesterday. Naturally, the mother and son went home. When the little guy finally left, he was still a little reluctant and insisted on being held by Li Zexuan. Strangely enough, this child was not allowed in the Li family. He kissed Father Li and Mrs. Li, but did not kiss Han Yuxi. On the contrary, he was very close to Li Zexuan who was often away from home, which made Mrs. Li laugh and call the child a heartless boy~!
The two brothers and sisters were walking on the trail in Yunshan. Although night had fallen, the roads in Yunshan were all cement roads and were considered smooth. They would not trip due to the bumpy road surface. It's late autumn now, and the cool night breeze blows on the body, making people feel a chill to the bone.
"You little girl, your mother asked you to wear more clothes when you went out, but you didn't wear them. Now you know it's cold, right?"
Seeing that Lan'er's legs were still shaking as she walked, Li Zexuan scolded her angrily.
Although he said this, he still took off the cloak from his back and wrapped it around the little girl.
Yes, that's right, Lan'er is short, and can only reach as high as Li Zexuan's waist at most. If such a long cloak is put on a little girl, half of it will be dragged on the ground. There's no telling if she'll step on the hem and trip herself up!
So, the lovely Laner was wrapped into rice dumplings!
"Ah! Stinky brother, this is so ugly! Take it off quickly~!"
Lan'er was just about to say, "Brother is so kind," but she was tricked into doing this by Li Zexuan. She, who has always loved beauty, could not bear this, so she immediately protested.
"You're so ugly! I'm going to get sick from the cold for a while. I wonder if you're still saying you're ugly!"
Li Zexuan knocked his sister on the forehead angrily, then dragged the latter towards the academy.
"Brother, brother! Can we really see the scenery on the moon soon?"
"Maybe! It depends on whether your brother Shaoning and sister Wei'er can do their best!"
"Awesome? Brother, what does "Awesome" mean?"
"emmmm...literally!"
"Huh, brother, you lied to me again, you definitely didn't mean it literally!"
"Uh... Geili means giving energy, bringing energy!"
"Oh... I hope brother Shaoning and sister Wei'er can help! Otherwise Lan'er's trip will be in vain... By the way, brother, is there Fairy Chang'e on the moon?"
"...Ha! Lan'er, you will know in a moment!"
The brother and sister chatted and talked, and after a while they arrived at Yanhuang Academy. The two went directly upstairs to the atrium.
Li Zexuan originally designed an atrium in the middle of the fourth to sixth floors of the twin main buildings in the center of Guanghua Building, with a semicircular glass zenith on the top for lighting. Now it can be used to place astronomical telescopes for astronomical observations!
After entering the atrium, Li Zexuan discovered that they were not the only ones here tonight. Li Tai, Sun Zifan, Cheng Chumo and dozens of other students were all here!
"Chief Shan~!"
When the students saw Li Zexuan coming, they all greeted him with more respect than before!
Some people at the bottom may not know that the reason why this cholera epidemic was quickly suppressed was because Li Zexuan contributed the prescription, but as students of Yanhuang Academy, how could they not know? After all, quite a few of them are very well-informed and spread the news from one person to another, so they basically all know that Li Zexuan is the "savior" of this plague!
Especially those students who had contracted cholera and were in good health looked at Li Zexuan with eyes filled with gratitude! Others learn skills from their masters. Not only do they learn skills from their masters, but they can also save their lives at critical moments. If you tell them, you will envy and ruin many people!
"Well! Have you all eaten~?"
Li Zexuan nodded and said pleasantly.
Now that the weather is getting colder, students no longer need military training. Naturally, they don't have to rush to the bathhouse to take a bath after school every day, so they still have some time to go out and move around before going to bed at night.
Li Zexuan had never thought about introducing an evening self-study system in the academy before, but the light at night was too poor. There were no electric lights in this era. Oil lamps and candles were no more than the light of fireflies in a large classroom with about forty students. , if you force late self-study, it will only damage the eyes of the students. After a few years, eight out of ten students will have similar eyes, which will not be beautiful!
"have eaten!"
As soon as Li Zexuan finished speaking, the students responded in a variety of ways.
At this time, Mo Lingwei walked over from the telescope and said excitedly: "Captain, can you come and take a look at this telescope? The students were clamoring to see it just now, but I didn't even let them see it!"
She was mainly afraid that the students would spoil her hard work over the past month.
Li Zexuan was angry and funny. He said "Yeah" and walked to the telescope.
He bent slightly and put his eyes on the eyepiece. There was no plastic in this era. The lens barrel was made of iron and was very cold to the touch.
The direction and angle of the telescope seemed to have been adjusted by Mo Lingwei in advance. Li Zexuan basically didn't need to make any adjustments before he saw a big glowing ball in the eyepiece! Some pitted grooves and winding ring-shaped mountains are vaguely visible on the sphere.
In his previous life, when Li Zexuan was studying in college in the capital, he went to the Capital Planetarium once. I remember that I had a student ID card at the time and the ticket cost only about ten yuan. There is a public observatory in the planetarium, which contains an optical catadioptric telescope with an aperture of 400 mm, through which you can observe the moon, planets, nebulae, star clusters, and sunspots during the day. That time Li Zexuan went there at night, and it was the first time he saw the clear appearance of the moon with his own eyes. The shock level was far beyond what the images on the TV screen could compare to!
The image resolution of the current telescope built by Mo Lingwei is naturally far inferior to the super-large astronomical telescope Li Zexuan used in the planetarium in his previous life, but this is the Tang Dynasty! It’s amazing to have a telescope that can see the outline of the moon!
"Well, not bad! Although there are a few flaws, they are worthy of encouragement. Miss Mo, congratulations on making the first astronomical telescope in the Tang Dynasty! Tomorrow I will help you convince Mr. Mo to agree to your stay in Yanhuang Academy!”
Li Zexuan watched for a while, then walked down and said to Mo Lingwei who was looking forward to him next to him.
