At night.

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

Lan'er's little tail naturally followed.

It is said that during the time that Han Xiaoyun's son Mei Zhihuan was in the Li family, Lan'er found a new playmate, and finally had a person younger than herself in the family, this girl naturally acted as a big sister, and many times the pretending to be an adult always made others laugh.

However, as early as the day before yesterday, Mei Zhihuan's condition had already recovered, and their mother and son naturally went home, and the little guy was still a little reluctant when he finally left, so he had to let Li Zexuan hug him, which is strange to say, this child is not close to Father Li, Mrs. Li, or Han Yuxi in the Li family, but is very close to Li Zexuan, who is often not at home, and makes Mrs. Li laugh and scold this child for being a little conscience~!

The brother and sister walked on the path of Yunshan, although night fell, the roads in Yunshan were all cement roads, which were smooth, but they would not trip because of the bumpy road. Now that it is late autumn, the cool breeze of the night blows on the body, making people feel a chill to the bone.

"You little girl, when you go out, your mother asks you to wear more clothes, but you don't wear them, now you know it's cold~?"

Li Zexuan saw that Lan'er's legs were still trembling while walking, so he reprimanded angrily.

Although he said this, he still took off the cloak on his back and wrapped it around the little girl's body.

Yes, it's wrapping, Lan'er is shorter, at most it can only be as high as Li Zexuan's waist, and if such a long cloak is draped on the little girl, half of it will be dragged to the ground. Maybe she'll step on the hem and trip herself up!

So, the lovely Lan'er was wrapped into zongzi!

"Yikes! Stinky brother, it's so ugly! Take it down~! ”

Lan'er just wanted to say "Brother is so good", but was wrapped up like this by Li Zexuan, where can she, who has always loved beauty, stand this, and immediately protested.

"Ugly you! I got sick after a while, I see that you are still ugly! ”

Li Zexuan knocked his sister's forehead angrily, and then dragged the latter and continued to walk towards the academy.

"Brother, brother! Will we really be able to see the scenery on the moon for a while? ”

"Perhaps! It depends on whether your brother Shaoning and Sister Wei'er can give it a lot! ”

"Awesome? Brother, what does it mean to give power? ”

“emmmm… That's what it means literally! ”

"Hmph, stinky brother, you lied to me again, it's definitely not literal!"

"Uh......... To give is to give strength, with the meaning of strength! ”

"Oh...... Then I hope that Brother Shaoning and Sister Wei'er will give you strength! Otherwise, Lan'er would have run for nothing...... By the way, brother, is there a fairy Chang'e on the moon? ”

“…… Scold! Lan'er, you'll know in a moment! ”

The brother and sister talked with each other, and after a while, they came to Yanhuang Academy. The two went upstairs directly to the atrium.

At the beginning, Li Zexuan designed an atrium in the middle of the fourth to sixth floors of the two main buildings in the center of Guanghua Building, with a semicircular glass ceiling on the top for lighting, which can now be used to place astronomical telescopes for astronomical observations!

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

"Mountain Chief~!"

When the students saw Li Zexuan coming, they saluted one after another, and their words were more respectful than before!

Some low-level people may not know that the reason why the cholera was quickly subsided this time was because Li Zexuan contributed a prescription, but how could they, as students of Yanhuang Academy, not know? After all, a considerable number of them are very well-informed, and the students basically know that Li Zexuan is the "savior" of this plague!

Especially those students who had cholera and were in good health, looked at Li Zexuan's eyes full of gratitude! Others are apprentices to learn art, their apprentices not only learn art, but also save lives at critical times, I don't know how many people will be envious when they say it!

"Hmmm! Have you eaten yet~? ”

Li Zexuan nodded and said with a pleasant face.

Now that the weather is cold, the students don't need military training, so naturally they don't have to run to the bathhouse to take a bath after school and eat every day, so they still have some time to come out and take activities before going to bed at night.

Li Zexuan didn't think about introducing the evening self-study system in the academy before, but the light at night is too poor, and if there are no electric lights, oil lamps, and candles in this era, for a large classroom with more than 40 students, it is tantamount to the glow of fireflies.

"I've eaten it!"

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

At this time, Mo Lingwei walked over from the telescope and said excitedly: "Mountain Chief, can you come and see this telescope?" I didn't even show it when the students were clamoring to see it! ”

She was mainly afraid that the students would ruin her hard work for more than a month.

Li Zexuan was angry and funny, said "um", and walked to the telescope.

He bent down slightly and pressed his eyes to the mouth of the eyepiece, there was no plastic in this era, and the barrel was made of iron, which was very cold to the touch.

The direction and angle of the telescope seemed to have been adjusted by Mo Lingwei in advance, and Li Zexuan basically didn't need to make any adjustments, so he saw a large round ball glowing from the eyepiece! Faintly visible on the sphere are potholed grooves and winding rolling rings.

When Li Zexuan was studying at a university in the capital in his previous life, he went to the Capital Planetarium once, and he remembered that he was holding a student ID card at that time, and the ticket was only about ten yuan. The planetarium has a popular observatory with an optical reflex telescope with an aperture of 400 mm, through which you can view the moon, planets, nebulae, star clusters, and observe sunspots during the day. That time Li Zexuan went at night, it was the first time he saw the clear appearance of the moon with his own eyes, and the degree of shock was far from being comparable to the pictures on the TV screen!

The imaging clarity of the telescope made by Mo Lingwei now is naturally far inferior to the super-large astronomical telescope that Li Zexuan used in the planetarium in his previous life, but this is the Tang Dynasty! It's nice to have a telescope that can see the outline of the moon!

"Well, not bad! Although there are a few flaws, but the flaws are not hidden, it is worth encouraging, Miss Mo, congratulations on making the first astronomical telescope in Datang! I'll help you convince Mr. Mo tomorrow! Let him agree to your stay in Yanhuang Academy! ”

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