late at night.

The bright moon hangs high in the sky, casting a soft silver light.

The Qin Mansion was silent, with only the breeze blowing gently through the treetops, and the leaves swaying in the wind, making a rustling sound.

Under the night sky.

A black shadow passed through the streets and alleys like a wisp of smoke, its figure as graceful as a crane emerging from a mountain.

In the blink of an eye, they arrived outside the Qin Mansion.

Then, the veil spun, and a beautiful slender foot lightly jumped onto the wall of Qin Mansion and slid in.

Suddenly, the figure that was as ethereal and graceful as a crane, dancing in the wind, suddenly stopped.

It turned out that her left leg was resting on a long thin wire.

There is a bell tied to this thin wire. The bell rings softly, but the sound is not loud and is hidden in the rustling of leaves.

The black shadow slowly moved its feet back little by little without making any sound until the thin line returned to its original shape.

She breathed a sigh of relief and groped forward more cautiously.

This person seemed to be very familiar with the Qin Mansion and knew the location of the Qin Mansion's organs like the back of his hand.

Even so, it took a lot of hardship and effort to finally reach Qin Yuan's house.

She stretched out her slender jade fingers and quietly opened a hole in the window paper.

Through the hole, I took a look at the situation inside the house.

(——h, like this.)

Suddenly, his ears turned red.

I spat in my heart: "Big pervert!"

Use... use your breasts?

Why is there such a trick?

Before she knew it, her mouth was dry.

Only inside the house.

Qin Yuan seemed to sense something, and suddenly raised his eyes and glanced towards the location of the black shadow. Then the corners of his mouth slightly raised, revealing an evil smile.

The black shadow raised his eyebrows, knowing that he was exposed, and ran away in a hurry.

…

In the palace.

Yan Jiaoran lay in bed, feeling upset, tossing and turning, unable to fall asleep.

"Yanran, what do you think this dog man is doing now?"

"Yanran, do you think the Golden Lotus can succeed?"

"Yanran, do you think this dog man is really Liu Xiahui?"

“…”

Yan Jiaoran chattered and muttered endlessly.

However.

Murong Yanran seemed to have heard nothing and was concentrating on looking at a piece of paper in front of her.

Yan Jiaoran was unhappy.

Why don’t you pay attention to me when this bastard is not around!

He got up immediately.

Tiptoe.

Quietly walked behind Murong Yanran.

He stretched his neck and looked at the piece of paper in front of Murong Yanran.

I only see a circle.

Apart from this circle, the paper is clean.

Well……

round?

It’s just a circle, and you’ve been looking at it all night?

Yan Jiaoran found it a little unbelievable.

She thought it was a love letter!

No……

wrong!

That's definitely not the case.

Maybe it’s a secret code between Yanran and that guy?

But such a circle.

What can such a circle represent?

Yan Jiaoran felt a little overwhelmed, and her breath was as fragrant as orchid, and the warm air was blown onto Murong Yanran's neck.

Murong Yanran sensed something was wrong, turned her head, and shuddered.

"Your Majesty... Your Majesty!"

Yan Jiaoran retracted her head, put her hands on her hips, squinted her eyes and smiled: "Hmm? Yanran, you are very dishonest."

"Tell me, what does the paper mean?"

"You've been staring at this paper all night!"

Murong Yanran's pretty face flushed as she explained, "Your Majesty, you misunderstood!"

“This is a question.”

“How do I calculate the area of ​​this circle?”

"According to the solution from previous mathematical classics, it's roughly to draw a square first, and then cut it off bit by bit."

"But no matter what I do, there will always be an excess, so the calculation won't be accurate."

"Your Majesty, look at this..."

Yan Jiaoran felt a headache after hearing this and quickly stopped Murong Yanran from saying anything further.

"You've been thinking about this question all night, nothing else?"

Murong Yanran folded the paper, put it back into her sleeve, and nodded, "Your Majesty, Yanran has indeed been thinking about this topic all night."

"What is it, your Majesty?"

"It's getting late, it's time to rest."

Yan Jiaoran glared at her with a look of annoyance, muttering something.

"Yanran, what do you think this dog man is doing now?"

Murong Yanran looked up at the sky outside and replied, "He should be asleep by now."

After spending three months with Qin Yuan, she was very familiar with his daily routine.

"Asleep..." Yan Jiaoran felt a little melancholy.

"It's getting late, Your Majesty should rest." Murong Yanran reminded.

Yan Jiaoran didn't answer. She frowned slightly and said with a wry smile, "Yanran, do you think Jinlian will succeed?"

Murong Yanran then remembered that Yan Jiaoran had sent Jinlian to "invite" Qin Yuan.

This move is completely in vain.

First of all, Jinlian's skills are not as good as Qin Yuan's.

Secondly, even if Jinlian could defeat Qin Yuan, how could she bring Qin Yuan into the palace without anyone noticing?

If Qin Yuan didn't cooperate, this would be impossible.

Murong Yanran sighed: "Your Majesty, it's getting late, it's time to go to bed."

Yan Jiaoran grumbled, still feeling a little hopeful: "Wait a little longer... just a little while..."

Murong Yanran shook her head helplessly.

Not long after, Jinlian came back.

Yan Jiaoran was overjoyed and took Jinlian's hand and asked, "Jinlian, how are you?"

Jinlian recalled the scene she saw in Qin's mansion, and a charming blush appeared on her delicate face.
