The First Lackey Under The Empress

Just as Zhao Du'an began popularizing physics.

In the deepest part of the Celestial Master's Mansion, in a quiet and secluded courtyard.

Under the banyan tree, the Great Yu Empress, dressed as a Kun Daoist today, also met the legendary figure of Great Yu, Zhang Yan Yi, the most senior and mysterious Celestial Master of the Daoist sect.

"You've come."

The tall Zhang Yan Yi, with his slender eyes and warm smile, had been waiting for a long time. He sat under the banyan tree, gesturing for the Empress to sit down.

Beside him, Jin Jian was also present, her role today being a page by her master's side.

She had abandoned her usual carefree temperament, and was now meticulously arranging the tea table, pouring tea for the two of them.

"Long time no see, Celestial Master's demeanor is even more impressive than before."

Xu Zhenguan, dragging her long skirt, walked to the empty bamboo chair, gracefully sat down, with a gentle smile on her face.

Zhang Yan Yi quietly sized her up, and sighed:

"Long time no see, Your Majesty's imperial aura grows stronger day by day, while your cultivation aura diminishes."

Xu Zhenguan's smile was bitter:

"Celestial Master's words are still so blunt. It's just that there are so many political affairs. I thought it would be easier to have someone share the burden, but the rebellious factions are restless…"

Zhang Yan Yi waved his hand, interrupting her, and closed his eyes, saying:

"I don't understand the major affairs of the court, old man. I still miss the days when Your Majesty came to discuss Daoist principles."

Xu Zhenguan was silent, understanding why the old Celestial Master had such an attitude.

She clearly remembered that when she was the Third Princess, she stayed in the Celestial Master's Mansion for a short period, and Zhang Yan Yi praised her talent for cultivation.

He once said that if she focused on cultivation, Xu Zhenguan had the hope of catching up with the Great Yu Emperor Taizu.

Because of this appreciation, he spent a lot of effort guiding and teaching her. However, in the end, Xu Zhenguan ascended the throne and became the emperor.

For the sake of major political affairs, she neglected her cultivation.

In the eyes of a worldly expert like the old Celestial Master, the mundane world is not worth mentioning compared to the Great Dao.

Therefore, he felt very sorry for Xu Zhenguan's abandonment of cultivation.

Because of regret, he was a little annoyed, but after all, it was a personal choice.

Although Zhang Yan Yi regretted it, he would not really be angry, just grumbling.

Seeing that the Empress did not answer, he took the initiative to open his mouth, found a few topics, and chatted.

In the end, he was still concerned about her cultivation.

However, with different inheritances, the higher they went, the more different the difficulties they faced.

The so-called conversation was just a superficial exchange.

However, for Jin Jian, who was sitting on a small bench, the sentences casually spoken by the two Heaven-Human Realm great cultivators were already obscure and difficult to understand.

So the girl had to hug her knees, stretch her neck, her small mouth slightly open, pretending to be focused, but in fact her eyes were scattered and her brain was blank.

If she made a few 'aba aba' sounds, she would be no different from a fool.

When Jin Jian came back to her senses, she found that the two had finally stopped talking about cultivation.

"When I came in, I saw a new couplet on the second gate tower. I wonder whose handwriting it is?"

Xu Zhenguan took a sip of tea and asked casually.

Jin Jian came back to her senses, focused her eyes, and vigilantly glanced at her, then at her master.

"Hehe, it was accidentally obtained by a subordinate divine official. This old man thought it was good, so I replaced it." Zhang Yan Yi said shamelessly.

Jin Jian admired it very much, thinking that her master's words were appropriate.

He didn't lie, just concealed key information.

Xu Zhenguan's beautiful eyes flickered.

Although curious, she didn't continue to ask, just said "Oh" and said:

"The Celestial Master's Mansion is indeed full of talents."

This sentence was originally just a polite remark, but it sounded a little wrong to the master and apprentice.

Thinking of the Empress suddenly mentioning the couplet and asking about its origin… Jin Jian looked at her master, thinking:

Could it be that Your Majesty knows something and came to imply us?

Zhang Yan Yi was also a little unsure.

After all, with his status, it would be really embarrassing to poach the Empress's corner.

"Ahem," the old Celestial Master adjusted his sitting posture, with the demeanor of a worldly expert, and said seemingly casually:

"Your Majesty's subordinates are also emerging with talents. Although this old man is sitting idly in the courtyard, I have also heard about it… Like Jin Jian'er, she mentioned someone named…"

"Zhao Du'an."

Jin Jian whispered, pursing her lips.

Thinking that her master was too shameless, still pretending not to know him, not knowing shame.

"Yes, Zhao Du'an," Zhang Yan Yi said with a smile, "He even brought his business to the Celestial Master's Mansion."

He tentatively tested, wanting to determine whether the Empress knew that he was poaching her corner.

Celestial Master Zhang even knows him… Did Jin Jian mention him… Xu Zhenguan was slightly surprised and smiled:

"This person is indeed somewhat intelligent. He also came with me this time, waiting outside. If the Celestial Master is interested, why not call him in?"

Her words didn't have much meaning.

However, it sounded like a formidable enemy to the master and apprentice.

Terrible… Does Your Majesty know?

Or is she suspicious?

So she deliberately brought him here, called him in to test, to embarrass the master in person… Jin Jian had a stern face, extremely serious.

She couldn't help but anxiously look at Zhang Yan Yi, wanting to see how the master would respond to Your Majesty's attack?

Zhang Yan Yi just gave the Empress a meaningful look:

"Jin Jian'er, since Your Majesty has spoken, you should go outside and ask. If that person is there, then lead him in to take a look."

"…Oh."

Jin Jian didn't know what her master was up to, and went out very honestly.

After a while, she came back.

The girl's expression was strange:

"Master, he… something happened outside."

The Empress and the old Celestial Master looked at her suspiciously at the same time:

"What happened?"

Jin Jian, thinking of what she heard when she went out, still couldn't believe it:

"They said that Zhao Du'an was invited by the Fifth Senior Brother, and then… somehow, he started giving lectures to the Fifth Senior Brother… Now, many divine officials have rushed over to watch the excitement, blocking that side tightly."

Xu Zhenguan was stunned, with an incredible expression on her face.

Zhao Du'an?

Giving lectures to Gongshu Tianyuan?

She couldn't help but look at the old Celestial Master inquiringly, but saw that Zhang Yan Yi was also confused.

The next second, he saw the old Celestial Master suddenly pick up the cup on the tea table and splash the tea in the air.

Swish!

In an instant, the tea in the air was splashed into a dynamic "screen" of water.

In the water screen, it was the tightly blocked courtyard, and the picture zoomed in, clearly showing Zhao Du'an's figure standing in front of a whiteboard, giving a lecture in the messy room.

Gongshu Tianyuan, and the other few craftsman god's warlocks, each moved a round stool and sat in front of him, listening attentively.

At this moment, Zhao Du'an's voice came from the water screen:

"…Therefore, if you want to understand why a lens can distort an image, you must first understand the refraction of light."

"What is refraction?"

"That is, when light obliquely enters another medium from one medium, the direction of propagation changes, so that the light is deflected at the interface of different media."

"…"

"…"

"Medium?"

In the room, Gongshu Tianyuan, sitting upright like a primary school student, ignoring the warlocks who were surrounding the courtyard, asked doubtfully:

"May I ask, Envoy, what is a medium?"

Zhao Du'an didn't answer immediately, just glanced helplessly at the dense faces on the windows in the courtyard.

Gongshu Tianyuan said nervously:

"Is the Envoy worried that they will hear the secrets of learning? Don't worry, I will drive them away…"

"…No need." Zhao Du'an sighed.

He just didn't understand why so many people came for no reason.

What if Your Majesty is looking for him?… Forget it, let's finish the lecture quickly, don't delay things.

Thinking of this, he calmed down and said:

"What is a medium? This is a good question. Well, to put it in a more vivid way, it is the substance that water waves, sound waves, and light waves rely on to propagate when going from one place to another."
