Yan Wangli, Chang'an Qing.

When there is a hint of the night coming.

Countless official mansions in Chang'an City are lit up.

Later in the day, countless large families followed.

When night fell completely, the entire Chang'an City was instantly shrouded in thousands of lights.

All kinds of lanterns and lanterns have completely turned Chang'an City, an ancient city that has experienced hundreds of years of wind and frost, into a city that never sleeps.

Thanks to Xu Yi's title of King Yan, from today onwards, Chang'an City will completely cancel the curfew in the next three days, which is to congratulate King Yan.

For a time, hundreds of people poured into the streets with their families.

In the past, it was an ordinary day, but because Xu Yi was named the king of Yan, it became as festive and lively as the Shangyuan Festival.

Inside the royal compound.

Wang Qiujin held a pot of wine, sat on the eaves, and quietly looked at Chang'an City, which seemed to be a city that never sleeps.

The lively sound in the market continued to reach Wang Qiujin's ears.

However, it was not attracted by the bustle and excitement.

Wang Qiujin slowly lifted the wine jug and saluted from afar towards the location of Jingzhao Mansion.

An indescribable smile instantly bloomed on his face that was as clear as water.

Under the illumination of various lanterns, it is really beautiful.

"Qing." Wang Qiujin said in a low voice, and then raised the wine jug to take a sip.

When the wine was in her stomach, a slight red appeared on Wang Qiujin's face, and a touch of silence flashed in her eyes.

"It would be nice to be able to congratulate you in person." Wang Qiujin muttered in a low voice, and then looked up at the crescent moon in the sky.

There is an indescribable loneliness and regret in his expression.

Just when Wang Qiujin was taking a sip of wine and admiring the moon.

Suddenly, there was a slight sound behind him.

Wang Qiujin turned her head to look.

I saw a black figure silently appear on the eaves under the moonlight.

Wang Qiujin stared blankly at the black shadow that was slowly approaching by stepping on the tiles, and in an instant he seemed to have forgotten even his breathing.

None of them.

The black figure was so familiar to her, so familiar that it seemed to be engraved in her bones.

The black figure quietly approached Wang Qiujin, and finally stopped half a step behind Wang Qiujin and slowly sat down.

The lights in this position cannot be reflected, but Wang Qiujin can see it very clearly.

As soon as the black figure took his seat, he leaned forward and picked up the wine jug in Wang Qiujin's hand lightly, raised his head and drank it lightly.

"You...... Why are you here?" Wang Qiujin came back to her senses, her face turned crimson and said, "Didn't Jingzhao Mansion celebrate tonight?"

The black figure is not someone else, it is Yan Wangyi, who has just been canonized today.

"Jingzhao Mansion has started since the time of the application, and it is really boring." Xu Yi put down the wine jug, leaned back, and lay on the eaves, with an indescribable relaxed look between his eyebrows.

As Xu Yi said, the celebration in Jingzhao Mansion had already begun, and it didn't end until half an hour ago.

The whole celebration banquet was full of hypocritical greetings, and Xu Yi described it as boring, which is really suitable.

"Can today's canonization ceremony be smooth?" Wang Qiujin glanced left and right, and after seeing that there was no one inside or outside the courtyard, she asked softly.

Xu Yi crossed his hands behind his head, looked at the half moon in the air, and replied, "Except for the cumbersome process, the rest is quite smooth."

Wang Qiujin nodded slightly, clasped her legs with her hands and raised her head slightly to look at the half moon in the air.

For a moment, the two people on the eaves fell silent.

But for some reason, although there was no word between the two, they were extremely reassured.

After a while, Wang Qiujin's breathing gradually came from behind him.

Looking sideways slightly, Xu Yi behind him didn't know when he had fallen asleep.

Wang Qiujin looked at the sleeping Xu Yi behind him, and wanted to wake him up.

But after seeing that he slept very sweetly, he couldn't bear it.

I wanted to go down to get a quilt for him, but I was afraid that Xu Yi would fall from the eaves after leaving.

For a while, Wang Qiujin really didn't go, and it wasn't okay if she didn't go.

Fortunately, it was already mid-April at this time, and the night in Chang'an City was not cold.

In desperation, Wang Qiujin had no choice but to slowly move back half a step, using her body to shield Xu Yi from some of the slightly noisy wind.

As soon as the slightly noisy wind was covered, the body was so close.

A slightly rich sense of wine instantly rushed into Wang Qiujin's nose.

But Wang Qiujin couldn't withdraw at this time, so she had to sigh slightly.

Time passed slowly.

One more day.

Two watches.

Three watches.

Until dawn was about to break.

Wang Qiujin moved her numb hands and feet slightly.

Then he gently shook Xu Yi's arm and said softly, "Wake up, it's almost dawn."

Although the two have set a marriage date, they have not yet married after all, and if they are discovered, it will inevitably be another verbal criticism.

Because of this, after Xu Yi arrived last night, he stopped behind Wang Qiujin.

And Wang Qiujin hid Xu Yi motionless behind him after he fell asleep.

As soon as Wang Qiujin shook two or three times, Xu Yi opened his eyes in a daze.

Xu Yi looked at Wang Qiujin beside him, then looked at the sky, and a blank look flashed in his eyes.

"It's almost dawn, it's time to go back, if someone sees you, you'll be in trouble." Seeing Xu Yi wake up, Wang Qiujin urged softly.

It was only at this time that Xu Yifang came to his senses completely.

At the celebration banquet in Jingzhao Mansion yesterday, Xu Yi was the protagonist of this time, and there were not a few people who drank water.

If it was in the past, I would have slept when I was drunk.

But yesterday, for some reason, Xu Yi came to the Wang family compound by ghost.

Due to the etiquette, Xu Yi did not enter directly, and wanted to turn around and leave, but at this moment, the leader of the heart reported that he found the princess on the eaves.

That's what happened last night.

Thinking of this, Xu Yi's back couldn't help but break out in layers of cold sweat, and the only trace of alcohol that remained instantly turned into nothing.

At the same time, the mind is constantly alerting itself, "Remember the cause and effect of today, and never regenerate the heart of laxity in the future."

In the final analysis, Xu Yi is also a human being, and it is impossible to keep his mind all the time if he is a human being.

The king who had been planning for half a year was able to get his wish, plus he drank some more wine during the banquet.

That's what happened last night.

"It's almost dawn." Seeing that Xu Yi was stunned, Wang Qiujin glanced at the sky and urged softly again.

Xu Yi calmed down, got up slowly, held Wang Qiujin's cold little hand, and gently rubbed it several times.

Then he whispered, "I worked hard for you last night."

Wang Qiujin felt the warmth in her hands, and her face couldn't help but turn crimson again.

Xu Yi glanced left and right, then hugged Wang Qiujin into his arms, and whispered in his ear, "I'll go back first, and I'll marry you."

As soon as the words fell, Xu Yi gently stamped a stamp on Wang Qiujin's forehead.

Immediately, in Wang Qiujin's eyes full of shame, he quickly left.

After Xu Yi leaves.

Wang Qiujin took dozens of deep breaths before she completely regained her composure.

......

......

Deep in the street not far from the royal compound.

Xu Yi, who was leaving the eaves, suddenly paused, and put his hands on his lips and blew slowly.

After a while, several inquiring guards dressed in black quietly walked out of the shadows of the street.

"Meet the master." As soon as several inquisitors walked out, they all saluted in low voices.

From the moment the canonization decree was issued, Xu Yi was already the true master of the conscience Baiwei.

Xu Yi looked at a few people and asked in a deep voice, "Can others see what happened last night."

A questioning person replied, "Back to the master, there were seven pairs of eyes near Wang's house last night, and all of them have been pulled out."

When he smelled seven pairs of eyes, Xu Yi couldn't help but feel a layer of cold sweat on his back again.

Fortunately, all seven pairs of eyes have been removed.

Ask what the strength of the heart Baiwei is, Xu Yi has already seen it more than once.

Now since the Conscience Baiwei said that all of them are pulled out, they are all pulled out.

There is still some confidence in this.

Xu Yi couldn't help but breathe a sigh of relief in his heart, and then waved his hand slightly to signal the conscience Baiwei to continue hiding in the dark.

......

......

When a ray of light breaks through the night and shines again on the world.

The one-night carnival has completely become the yellow flower of last night.

Chang'an City is once again busy in its past.

The inner house of Jingzhao Mansion.

Xu Yifang finished washing up and was about to start practicing the eight vajra exercises.

There was a sudden knock on the door of the inner house.

"Your Highness, the head of the household is still asking to see you." Zhang Kaiyuan's voice came along with the knock on the door.

'Tian Yichu? , Xu Yi muttered when he heard this: "I thought you wouldn't come." ，

Xu Yi put down the towel in his hand and said calmly, "Please go to the side hall."

"Yes." Zhang Kaiyuan agreed, and then quickly turned around and left.

It didn't take a while.

Xu Yi was dressed in a black robe and walked into the side hall of the front hall unhurriedly.

"Meet His Royal Highness King Yan." Tian Yichu got up and bowed.

Xu Yi bowed his hand slightly as a salute, and then said, "Tian Shangshu, please take a seat."

"Yes." Tian Yichu agreed, and waited for Xu Yi to take a seat before taking a seat.

After all, this time is different from the past, and now Xu Yi is already a prince with real power.

And the prince is the first to be the son of heaven, and the crown is the first in the Cheqi Mansion.

Even if it is seen by the six books, it is necessary to bow.

"Tian Shangshu is here to settle accounts this time?" Xu Yi lifted the teapot and poured a cup of tea for him, and then got straight to the point.

Tian Yichu got up slightly, took the teacup and replied, "Your Highness Mingjian."

After the words fell, Tian Yichu paused and continued: "Now the remaining disaster relief food in Jingzhao Mansion has been put into storage."

….

"However, there are so many accounts that even if the household officials turn around, they will not be able to put together all the accounts in the time set by His Majesty."

"I heard that Your Highness has a more convenient way to settle accounts here."

"Dare to get it."

Xu Yi smiled when he heard this, didn't say much, and directly took out an object from the hem of his sleeve.

Place it on the table and slowly push it to Tian Yichu's side.

"Your Highness, what is this?" Tian Yichu looked at the finger-thick account book on the table and said in surprise.

Xu Yi slowly spoke: "This is the method used by Xiao Wang to close accounts during the disaster relief period."

In the company of smart people, sometimes honesty is ten million times better than scheming.

And Tian Yichu is a smart person in Xu Yi's eyes.

Tian Yichu got up and bowed heavily when he heard this, and said solemnly: "Your Majesty has thanked His Royal Highness King Yan first."

The lower officials thanked first, not the lower officials thanked the officials of the household department first......

"Tian Shangshu has tormented the boy." The corners of Xu Yi's mouth rose slightly, and then he got up and helped Tian Yichu up.

After Tian Yichu got up.

Xu Yi slowly spoke again: "This method was born from the Nine Chapters of Arithmetic, and it should have been handed over to Tian Shangshu after the court meeting that day."

"But at first, Xiao Wang just knew how to use it, and he couldn't use it

Sort it out completely."

"After it was completely sorted out by Xiao Wang, it was canonized again, and it was completely delayed."

Tian Yichu arched his hand and said, "With His Royal Highness King Lao Yan, this great favor will definitely be remembered by His Majesty."

Xu Yi smiled, and then changed the topic and said, "Tian Shangshu will check it first, and if there is anything unclear, you can ask Xiao Wang at any time."

Tian Yichu thanked him again, and then picked up the account book and slowly flipped through it.

If you hear Xu Yi's explanation again, Tian Yichu still has a little displeasure in his heart.

Then, as the account book slowly opened, the slightest displeasure in his heart was instantly completely replaced by gratitude.

None of them.

The first page of the book was filled with all sorts of strange symbols.

Although Xu Yifang just mentioned that this method was born from the nine-chapter arithmetic, in fact, Tian Yichu could not see the slightest shadow of the nine-chapter arithmetic in the account book.

Tian Yichu's face was puzzled: "His Royal Highness King Yan, this ......"

Xu Yi glanced down at what Tian Yichu was pointing at, and then slowly explained: "This method was born from the nine chapters of arithmetic, and these special symbols mirror each other with the numbers in the nine chapters of arithmetic."

「......」

「......」

As Xu Yi explained word by word, Tian Yichu instantly understood that this was just a more convenient way to convert the nine chapters of arithmetic into a more convenient way of calculation.

But soon, as Xu Yi gradually explained in depth.

Tian Yichu gradually realized that he was thinking things too simply.

This method is derived from the nine chapters of arithmetic, but it has its own set of rules.

However, the core of this set of rules itself is consistent with the arithmetic of the nine chapters.

To put it simply, Xu Yi re-improved the nine-chapter arithmetic in another way.

It simplifies the arithmetic of the nine chapters as a whole, making it easier to calculate and learn.

Thinking of this, Tian Yichu couldn't help but be excited: "Great talent! What a talent! This magic is in the future! It's a long way off!"

"Tian Shangshu?" Seeing that Tian Yichu had not spoken for a long time, Xu Yi couldn't help but look up at Tian Yichu.

….

'Huh? , Tian Yichu muttered, and then came back to his senses in an instant.

He asked worriedly, "His Royal Highness King Yan, this method ...... Can this law be passed on?"

As soon as the words fell, Tian Yichu looked at Xu Yi worriedly, for fear that he would not agree.

Xu Yi chuckled, and then replied, "This method will be tried in the household department first."

"In the past few days, Xiao Wang has reorganized and compiled it to make it easier to learn and disseminate."

"When the time comes, Xiao Wang will push it into the world."

The voice fell.

While Tian Yichu breathed a sigh of relief, he quickly got up and saluted solemnly: "King Yan, the lower officials admire."

Xu Yi smiled noncommittally, and then motioned to Tian Yichu to continue studying.

In fact, this is a plan set by Xu Yi in advance, how can there be no talk of not promoting it?

The reason why it has been delayed until now is nothing more than waiting for an opportunity to maximize benefits.

At this time, there is no need to worry about false accounts during the disaster relief period.

Second, you can take this opportunity to make the head of the household department Shangshu Tian Yichu grateful to him.

Thirdly, after the trial implementation of the household department and the good results, the household officials will spontaneously promote it, so that when Xu Yi officially writes a book and implements it all over the world, it will achieve twice the result with half the effort.

Fourth, once this book is thoroughly promoted, Xu Yi will completely occupy a place in the literary world.

How many people are there in the world? As long as a small part of this can be used by Xu Yi, it is enough to make it even stronger.

Why not kill four birds with one stone?

Moreover, these are only obvious benefits, as for the more subtle benefits, there will only be more and not less.
