Otaku Engineer in Great Tang Dynasty Chapter 928: Datang’s first astronomical telescope!

At night.

After eating, Li Zexuan went out and walked towards Yanhuang Academy.

Lan'er, the little tail, naturally followed.

Speaking of Han Xiaoyun’s son Mei Zhihuan during the period of time in Li’s family, Lan Er found a new playmate, and finally had a younger person in the family. This girl naturally acted as When I started my eldest sister, the pretending to be an adult always made others laugh.

However, as early as the day before yesterday, Mei Zhihuan’s condition was already healed. Naturally, their mother and son went home. When the little guy finally left, he was a little reluctant to let Li Zexuan hold him. It’s strange to say that this child is here. The Li family does not kiss Daddy Li, Mrs. Li, or Han Yuxi. Instead, they are very close to Li Zexuan, who is often absent from home, so that Mrs. Li laughs and scolds this child as a little heartless~!

The two brothers and sisters are walking on the trails of Yunshan. Although night is falling, the roads of Yunshan are all cement roads, which are flat, and they won't trip over the rough road. Now that it is late autumn, the cool night breeze blows on the body, making people feel a burst of chill.

"You little girl, when my mother asked you to wear more clothes when you went out, you just didn't wear it. Now you know it's cold~?"

Li Zexuan scolded angrily when he saw Lan'er's legs trembling as he walked.

Although he said so, he took off the cloak on his back and wrapped it around the little girl.

Yes, it's just wrap. Lan'er is short and can only reach the height of Li Zexuan's waist at most. If such a long cloak is put on the little girl, half of it will be dragged to the ground. Forget that she would step on the hem and trip herself over!

So the cute Lan'er was wrapped into zongzi!

"Ah! Brother smelly, this is so ugly! Take it down now~!"

Lan Er just wanted to say "Brother is really nice", but Li Zexuan made it into this. She who has always loved beauty, how could she stand this, she immediately protested.

"You are so ugly! After a while, you will be sick, I think you still say ugly!"

Li Zexuan knocked his younger sister on the forehead unhappily, then dragged the latter to continue toward the college.

"Brother, brother! Can we really see the scenery on the moon in a while?"

"Perhaps! It's up to your brother Shaoning and sister Weier to fail!"

"Geely? Brother, what do you mean by force?"

"emmmm... literally means!"

"Hmph, brother smelly, you lied to me again, definitely not literally!"

"Uh... to be strong means to be strong, to be strong!"

"Oh... Then I hope that Brother Shaoning and sister Weier will work harder! Or Lan'er will run for nothing... By the way, brother, is there Fairy Chang'e on the moon?"

"...Heh! Lan'er, you'll know in a while!"

The two brothers and sisters spoke with each other, and they came to Yanhuang Academy after a while. The two went straight upstairs to the atrium.

At the beginning, Li Zexuan designed an atrium in the middle of the fourth to sixth floors of the main double main building of the Guanghua Building, with a semicircular glass zenith on the top for lighting. Now it can be used to place an astronomical telescope for astronomical observation!

After entering the atrium, Li Zexuan realized that there were not only their brothers and sisters here tonight, but dozens of students, including Li Tai, Sun Zifan, and Cheng Chumo, were all there!

"The mountain is long~!"

When the students saw Li Zexuan coming, they all saw the ceremony, and their words were more respectful than before!

Some people at the bottom may not know that the reason why the cholera can be resolved quickly this time is because Li Zexuan contributed the prescription, but how could they, as students of Yanhuang Academy, not know? After all, quite a few of them are very well-informed, and the students basically know that Li Zexuan is the "savior" of this plague!

Especially those students who are in good health with cholera, look at Li Zexuan with gratitude! Others are apprentices to learn art. They not only learn art, but they can also save lives when it is critical. I don't know how many people would be envious of it!

"Hmm! Have you all eaten~?"

Li Zexuan nodded, and said in a pleasant tone.

Now the weather is cold, and the students don’t need military training anymore. Naturally, they don’t have to go to the bathhouse every day after school and eat to grab a bath, so at night they have some time to go out before going to bed.

It’s not that Li Zexuan had never thought of launching an evening self-study system in a college, but the light at night is too poor. In this era, there are no electric lights, oil lamps, or candles. For a large classroom with about forty students, it is no different from a firefly. Huo Zhihui, if you forcefully engage in late self-study, it will only ruin the eyes of the students. After a few years, eight out of ten students are similar eyes, which is not beautiful!

"Eat it!"

As soon as Li Zexuan's voice fell, the students responded rushingly.

At this moment, Mo Lingwei came over by the telescope and said excitedly: "Zhang Chang, can you come and see this telescope? The students just clamored to see it, but I didn't show it!"

She was mainly afraid that the students would ruin her hard work over the past month.

Li Zexuan was angry and funny, and walked to the binoculars with an "um".

He bends down slightly and puts his eyes on the eyepiece opening. There is no plastic in this era. This lens barrel is made of iron, and it feels cold to the touch.

The direction and angle of the telescope seemed to be adjusted by Mo Lingwei in advance. Li Zexuan basically didn't need to make any adjustments, so he saw a big luminous ball in the eyepiece! On the sphere, some cratered grooves and winding undulating mountains are faintly visible.

Li Zexuan went to the Capital Planetarium once when he was studying in the capital in his previous life~IndoMTL.com~. I remember that I took my student ID and the ticket was only ten yuan. There is a public observatory in the planetarium with a 400-millimeter optical reflex telescope through which you can observe the moon, planets, nebulae, and star clusters, and observe sunspots during the day. That time Li Zexuan went there at night. It was the first time he saw the clear appearance of the moon with his own eyes. The shock was far beyond what the picture on the TV screen could compare!

The telescope made by Mo Lingwei is naturally far less clear than the super-large astronomical telescope used by Li Zexuan in the planetarium in his previous life, but this is the Tang Dynasty! It is already very hanging to have a telescope that can see the outline of the moon!

"Well, not bad! Although there are a few flaws, but they are not concealed, they are worthy of encouragement, Miss Mo, congratulations on making the first astronomical telescope of the Tang Dynasty! Tomorrow I will help you convince Mr. Mo! Let him agree with you Stay in Yanhuang Academy!"

Li Zexuan looked for a while, then walked down, and said to Mo Lingwei, who was looking forward to the side.
