Otaku Engineer in Great Tang Dynasty

at night.

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

Lan'er, the little tail, naturally followed.

By the way, during the period when Han Xiaoyun’s son Mei Zhihuan was in Li’s family, Lan Er found a new playmate, and she finally had a younger person in the family. This girl naturally became a big girl. Sister, many times the pretending to be an adult always makes others laugh.

However, as early as the day before yesterday, Mei Zhihuan’s condition had been cured. The mother and son naturally went home. When the little guy finally left, he was a little reluctant to let Li Zexuan hold him. It is strange to say that this child is not in Li's house. Daddy Li, Madam Li, nor Han Yuxi, but very close to Li Zexuan, who is often absent from home, and made Madam Li laugh and scold this child as a little unscrupulous~!

The two brothers and sisters were walking on the trails of Yunshan. Although night fell, the roads of Yunshan were all cement roads, which were flat and would not trip over the rough roads. 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 them. Now you know it's cold~?"

Seeing that Lan'er's legs were still trembling as he walked, Li Zexuan rebuked.

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

Yes, just wrap, Lan'er is short, and can only reach the waist height of Li Zexuan 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!

As a result, the lovely Lan'er was packaged 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 gave it to her. She who has always loved beauty, how could she stand this, she immediately protested.

"Ugly, you're so ugly! After a while, Jie got sick, I think you still say ugly!"

Li Zexuan knocked his younger sister's forehead unhappily, then dragged the latter to continue toward the academy.

"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!"

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

"Emmmm... literally!"

"Huh, 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 Wei'er 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 were talking together and not, 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 central double main building of the Guanghua Building, with a semi-circular 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, Cheng Chumo, etc. were all there!

"Mountain 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 is resolved quickly this time is because Li Zexuan contributed the prescription, but how could they be students of Yanhuang Academy not knowing? After all, quite a few of them are very well informed, and the students basically know that Li Zexuan is the "savior" of the 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 save their lives when it is critical. I don't know how many people would be envious of it!

"Hmm! Have you all eaten yet~?"

Li Zexuan nodded and said in a pleasant tone.

Now that the weather is cold, 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 take a shower, so at night they still 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 the academy, but the light at night is too poor. If there are no electric lights, oil lamps, and candles in this era, it would be tantamount to the glow of fireflies in a large classroom with about forty students. If you forcibly engage in late self-study, it will only spoil the eyes of the students. A few years later, eight out of ten students are similar eyes, which is not beautiful!

"Ate!"

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

At this moment, Mo Lingwei walked over from the telescope and said excitedly: "Chairman, can you come and see this telescope? Just now the students 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 side of the telescope with an "um".

He bends down slightly and put 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 have been adjusted by Mo Lingwei in advance. Li Zexuan basically didn't need to make any adjustments, and he saw a big shiny 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~www.ltnovel.com~. I remember that I was holding my student card and the ticket was only ten yuan. There is a public observatory in the planetarium, which has 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, it's not bad! Although there are some flaws, but the flaws are not concealed, it is worth encouraging, Miss Mo, congratulations on making the first astronomical telescope of the Tang Dynasty! Tomorrow I will help you to convince Mr. Mo! Let him agree to your stay in Yanhuang Academy!"

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