Sky Curtain: With a vermilion mirror, Jing travels through the modern world, shaking all dynasties.

In front of the residential area, two completely unrelated figures stood hand in hand by the roadside.

Jiang Chuan, dressed in a suit and tie, looked like a successful young entrepreneur.

In contrast, Zhu Jingjing beside him was dressed in a snow-white Hanfu, with flowing ribbons, exuding an ethereal aura.

"What are you two doing dressed like this...?" Lin Xiaoyu looked at the two siblings helplessly. Although they were holding hands, their styles were completely different. "Jiang Chuan, how many times have I told you? You don't need to dress so formally to be a lecturer. People who don't know better would think you're going to represent China in talks with the United States!"

Jiang Chuan scratched his head awkwardly and said, "It's a formal occasion after all, so it's always good to dress formally."

Lin Xiaoyu shrugged. It was too late to change now. "You've all had breakfast, right? Then get in my car, and we'll go straight to the university."

In front of Yenching University's main gate, the three people with their distinct styles attracted a lot of attention, and students frequently cast curious glances at them.

"Brother, why is everyone secretly laughing?" Zhu Jingjing asked, looking puzzled.

"Jingjing, it's not your fault, it's all your unlucky brother's fault." Lin Xiaoyu rolled her eyes at Jiang Chuan and said, "You go inside and get ready, I'll show Xiaoyu around."

Jiang Chuan was taken aback and asked, "What, you don't need to prepare anything?"

"I don't need to be a lecturer, so what's there to prepare?" Lin Xiaoyu said.

"Then why did you come along?" Jiang Chuan asked in confusion. He thought Lin Xiaoyu was also going to give a lecture, so she came with them.

"I came because I wanted to, what's it to you!" With that, Lin Xiaoyu ignored him and took Zhu Jingjing's hand. "Jingjing, how about I show you around today?"

Zhu Jingjing glanced at Jiang Chuan and nodded somewhat reluctantly. She had only met Lin Xiaoyu once, and she still preferred to be with Jiang Chuan.

"Jingjing, you must listen to your sister Xiaoyu and don't run around!" Although Jiang Chuan was a little worried, he still had to go on stage to give a lecture. Rather than letting the little princess wait, he might as well go for a walk with Lin Xiaoyu.

After Jiang Chuan left, Lin Xiaoyu asked, "Jingjing, do you want to see what your brother looks like when he's lecturing?"

Upon hearing this, Zhu Jingjing nodded vigorously. Although she wasn't particularly interested in attending classes, the thought of Jiang Chuan reciting his lessons with his head swaying like those old scholars in the Imperial Academy made her want to go and see.

"Let's go then. I've already checked where he'll be giving his lecture!" Lin Xiaoyu smiled slyly. She knew Jiang Chuan very well; that guy definitely didn't want acquaintances to see him as a lecturer.

That's why she hadn't mentioned going to watch him teach, so as to give him a "surprise".

Lin Xiaoyu led Zhu Jingjing into the university campus, her eyes filled with curiosity as she looked at the vibrant young people around her.

This was completely different from the Imperial Academy she remembered. There were no students who spoke in classical Chinese, nor were there any unchanging scholar's caps and robes.

"Sister Xiaoyu, this Imperial College is huge!" Strolling through the vast campus, Zhu Jingjing couldn't help but exclaim in amazement, "It's probably a hundred times bigger than I remember!"

"The Imperial Academy?" Lin Xiaoyu was taken aback. She naturally knew what the Imperial Academy meant, but in modern times, no one would call a university the Imperial Academy.

Realizing her slip of the tongue, Zhu Jingjing quickly covered her mouth, "No, I meant university!"

Lin Xiaoyu frowned slightly. She had vaguely sensed that Zhu Jingjing was acting strangely. Even if she had never seen a drone before, she should at least know what it was for.

"Jingjing, where did you live before?" Lin Xiaoyu asked tentatively.

"I'm in the mountainous northwest. I only recently came here to my brother's place." Zhu Jingjing's heart was in her throat. Luckily, Jiang Chuan taught her some conversation skills yesterday, otherwise she would definitely have been speechless.

Lin Xiaoyu nodded with some skepticism. It was understandable that Zhu Jingjing, who lived in a relatively underdeveloped mountainous area, had never heard of drones.

But even children from mountainous areas wouldn't call a university the Imperial College, would they?

Lin Xiaoyu's eyes darted around. She glanced at her watch; there was still some time before Jiang Chuan's lecture. She suggested, "Jingjing, how about we go to the astronomical observatory first?"

Hearing this, Zhu Jingjing's curiosity was piqued, and she asked, "Sister Xiaoyu, does astronomy refer to the sun, moon, and stars?"

Lin Xiaoyu's heart skipped a beat. Judging from Zhu Jingjing's words and actions, she was clearly not uneducated, yet she didn't even dare to define the word "astronomy." There was definitely something strange about this!

"That's right. To be more precise, it refers to the positions of celestial bodies such as the sun, moon, and stars in the universe, as well as their movements and patterns of change," Lin Xiaoyu said.

Zhu Jingjing seemed to be deep in thought. Jiang Chuan had previously explained some basic astronomy knowledge to her, which had piqued her interest. "Sister Xiaoyu, let's go!"

Led by Lin Xiaoyu, the two quickly arrived at the astronomical observatory.

"Xiaoyu, what is this?" In her excitement, Zhu Jingjing had long forgotten Jiang Chuan's instructions and turned into a curious child.

"This is an astronomical telescope, which can be used to observe celestial bodies in the universe." Lin Xiaoyu pointed the telescope at the sun and said, "Do you want to see what the sun looks like? Ordinary astronomical telescopes cannot directly observe the sun, but this one uses a professional solar filter, which can effectively reduce the intensity of sunlight to a safe level and block harmful ultraviolet and infrared rays."

A string of technical terms left Zhu Jingjing completely bewildered, but since Lin Xiaoyu had said it was safe, she couldn't wait to get to the eyepiece.

Three Kingdoms, new fields.

"Is this the true face of the sun?" Looking at the orange-red disc appearing in the sky, Liu Bei couldn't help but exclaim, "No wonder the sunlight feels warm; you can feel how high its temperature is just by looking at it!"

Zhuge Liang frowned deeply, his feather fan falling to the ground. "The Huainanzi tells of Hou Yi shooting down the suns, which now seems utterly laughable. What kind of bow and arrow could possibly bring down such things!"

Even Zhang Fei, who was usually loud and boisterous, was so shocked that his eyes widened and he remained silent.

The Great Tang Dynasty, Taiji Hall.

Little Sizi clung tightly to Li Shimin's dragon robe, her voice trembling with tears, "Father, so this is what terrifying things are above us! What if it falls down one day!"

Li Shimin held the little girl tightly in his arms and gently covered her eyes with his palm. "Don't be afraid, little girl, it's all fake."

The Great Ming Dynasty, Fengtian Hall.

Zhu Yuanzhang sat upright on the dragon throne, his gaze dark as he watched the civil and military officials bow and kowtow to the heavens.

"It's just a big fireball, what's there for you to be afraid of?" Zhu Yuanzhang slammed his hand on the dragon throne and shouted angrily.

"Zhongba, you can't blame everyone for this." Empress Ma's voice trembled, a rare occurrence. "If this thing falls, then our Great Ming..."

"A man who worries about nothing!" Zhu Yuanzhang sneered. "If it were to truly fall, not only would the Ming Dynasty cease to exist, but the entire world would cease to exist! But since the future in the heavens still exists, what is there to worry about!"
