And more are names of people unheard of in later generations, whose abilities are unknown, but it can be estimated that they are probably not very high either:

After all, when Old Su was creating the new instrument, a large amount of mathematical calculations was needed, and at that time, he basically searched all over Bianjing for mathematicians, and had a deep understanding of the whole mathematics circle of Bianjing.

Unless they are some up-and-coming talents, otherwise their abilities obviously couldn't be very strong.

As things have reached this point, today's lesson naturally is almost over.

Then Old Su thought about it and cheerfully said to Xiaozhao and Xiaoli:

"Prince Jian, Qingzhao, why not stay for dinner at the mansion before leaving?"

Xiaoli and Xiaozhao exchanged a glance and declined by saying:

"Your Grace Junior Master, it was kind of you, but I still need to return to the palace early to find artisans, after all, you know about my brother... so let's schedule it for next time, definitely next time."

Looking at this enigmatic person with a face of 'you understand', Xu Yun blinked in confusion.

As a non-history major science enthusiast, he naturally did not understand.

In this short period after he ascended to the throne, Emperor Huizong of Song had already shown a few traits of the Flower and Bird Emperor:

Spending at least three hours each day on painting and calligraphy, occasionally switching to playing cuju or some other activities.

His brothers could only see him in the afternoon during the hour of Shen.

Of course.

His claim to Empress Dowager Xiang was that he enjoyed reviewing memorials alone, and since Empress Dowager Xiang died early, she was really deceived by Emperor Huizong before her death.

When Empress Dowager Xiang, this low-budget version of Cixi, was alive, Zhao Ji dared to do this, but he became timid when the Jin army came, which is quite ironic.

Then Old Su returned to the study to start writing a letter to Jia Xian, while Xiaoli and Xiaozhao were entrusted to Xu Yun to see them off.

After all, Xu Yun is currently both a "teacher" and a guest, making it appropriate for him to see off Xiaoli and Xiaozhao given his status.

Old Su's courtyard wasn't very large, and since the venue where the lesson took place was in the front yard, it was only a short distance from the main gate.

In just a short walk, the three reached the entrance.

"Mr. Wang."

Just before they parted, Xiaozhao took the initiative to cup his hands towards Xu Yun:

"As the ancients said, listening to your words is better than reading for ten years.

The words of Mr. Wang today truly enlightened me; the concepts of gravity and the planets... I'm afraid I'll never forget them in this lifetime."

Xiaozhao's expression and tone were sincere, and it was indeed from his heart, not just polite words.

After all, if he weren't interested in science, he wouldn't have followed Xiaoli to come to Old Su's mansion to meet Xu Yun — at that time, Xiaoli still didn't know that Xu Yun had been promoted; a prince meeting a servant, this had already exceeded the concept of lowering one's status to make friends.

On the other hand.

Xu Yun also had a good impression of this dashing gentleman, seeing him was like seeing the equally dashing reader:

"Prince Jian flatters me, I'm just relaying the content of the notebooks written by the sages, similar to an instructor of elementary learning, teaching the sacred books, anyone else could do the same.

The real admiration should be for the wisdom of the sages, as vast as the sea of stars, yet so much has been buried in the passage of time."

Xu Yun's words seemed to touch a chord in Xiaozhao's heart, and he sighed:

"Indeed, if Mr. Wang hadn't mentioned it, I'm afraid I would have never known in my entire life that there exists such a mystical sect as Wind Spirit Moon Shadow.

Oh yes, Mr. Wang, is it true that currently, you're the only one left in Wind Spirit Moon Shadow?"

Upon hearing this, a trace of sorrow flashed in Xu Yun's eyes, his face showed bitterness and heartache:

"Wind Spirit Moon Shadow has long dissipated in the tides of time, I was merely lucky, a fortuitous happenstance gained me a broken legacy.

Just like the astronomical telescope, many heritages are now fragmented, we later generations only hear of them by name, never seeing them, alas....."

Xiaozhao shook his head wistfully, then lightly coughed to console:

"Mr. Wang, people should look forward, let's not talk about melancholic words anymore,

As for the matters of artisans and finances, once I return to the palace, I will make arrangements, striving to restore this wonderful astronomical telescope at the earliest!"

Xu Yun nodded, instinctively wanting to advise this Prince Jian to move out of the imperial palace.

But considering it was inappropriate to speak so deeply in light acquaintance, in the end, he could only transform his depression into a deep sigh.

He then glanced at Xiaoli beside him, forcing a slight smile:

"Miss Li, let us part for the day."

At this time, Xiaoli was drooping the corners of her eyebrows, somewhat sullenly waved at him:

"Sorry, Wang Lin, I can't help with this astronomical telescope..."

"Oh, what does it matter?"

Xu Yun gestured indifferently to her and said with a smile:

"Miss Li, don't worry, we have plenty of time, maybe the next chapter... cough, cough, next time, I will have something to trouble you with!"

Xiaoli still nodded weakly, but soon thought of something.

With some anticipation and nervousness, she said to Xu Yun:

"Wang Lin, when they start making the astronomical telescope, can I still come to the workshop?"

Xu Yun nodded firmly, gladly agreeing:

"Of course you can."

Only upon hearing this did Xiaoli regain some energy, letting out a soft sigh of relief.

After all, although women's status in the Song Dynasty was not low, an unmarried girl mingling with a bunch of men still challenged traditional views somewhat.

Xiaoli herself wasn't worried, but her father, Comrade Li, had already resigned himself to it.

Therefore, the biggest obstacle came from this side with Xu Yun and Old Su.

After all, scholars esteemed themselves highly, people like Old Su feared ruining their late stages of life and might find ways to refuse.

Seeing Xu Yun personally agree to let her observe a round of the telescope's manufacture thus meant overcoming the biggest obstacle.

After a few more simple courtesies, the three parted at the door.

Xu Yun followed the courtyard path and returned to the East Wing.

He planned to rest a little longer, and at the same time, organize the knowledge points he was about to write down for Jia Xian.

If there was still time.

He would consider what steps to take next.

As he approached his courtyard, before he even entered the gate.

He saw Wang Bing, this stern-faced man, standing like a pillar at his courtyard entrance.

Seeing this situation.

Xu Yun instinctively felt a shock:

Could it be that something has happened again to Wang Yue?

After all, they only passed through the period of highest risk before, far from being out of danger.

In the inadequate medical environment of the Song Dynasty, anything could happen at any time after antibiotic injections.

So he hurried forward, cupped his hands to Wang Bing, and asked somewhat anxiously:

"Captain, you've come to see me? Could it be that there's a change in Zhonghou's condition?"

Seeing Xu Yun's concern for Wang Yue, Wang Bing's heart was immediately warmed, he waved with a smile:

"Xiaowang, you can rest assured, my brother's condition is fine, I'm here mainly for you this time."

Xu Yun was puzzled, pointing at himself with his index finger:

"Me?"

Wang Bing nodded, took out a few bound books from his body:

"Without you, Xiaowang, saving grace is unrepayable."

"This morning, I couldn't stop thinking, noticing that your physique seems a bit thin, so..."

"Here are a few secret martial arts manuals, although they are not superior martial arts, they can be mastered quickly; are you interested?"
