Cheng Yanjin said vaguely, only said the criticality of the matter, and refused to reveal who Yi's father was.

Zong Xiu snorted: "Doesn't my brother still believe me? Rest assured, although the abacus is ordinary, it can be matched with my mantra to ensure that it can make another storm in the world. ”

After speaking, Zong Xiu pretended to regret again: "Hey, it's a pity that such a treasure is not used to add an official to himself and change to a Qinglou woman." ”

Cheng Biting Jin hurriedly said: "Don't." Yi Yatou has been suffering for more than ten years, and now that she has reached the age of leaving the cabinet, she can't stay in that place for the rest of her life. ”

"Hehe, then you tell me who Yi Qingqing's father is." Zong Xiu asked with a smile.

"This ......"

Cheng Yanjin hesitated.

First, he didn't dare to say it until Yi was free.

Second, he didn't want to say it either.

After all, it was a past that these old buddies who came out of Wagangzhai didn't want to mention, a scandal that made them embarrassed.

When the man died, they did not dare to intercede.

After that person died, although they kept Yi Tingqing, they couldn't let Yi Qiqing grow up like a normal child.

Although they tried their best to ask for their lives, after protecting the deceased. But it also led to the deceased living in the Qinglou later. Although His Majesty decreed that he would not sell his body, it was not a good reputation after all.

After so many years, Cheng Yanjin also figured it out: His Majesty still hates that person. The reason why they were willing to keep Yi for his life back then was not all because of their face, but because they deliberately humiliated that person.

Giving birth to a man as a slave and a girl as a prostitute is the most vicious curse in the market, but His Majesty has made this curse a reality.

Pathetic, lamentable......

Over the years, they, the old buddies who know the inside story, have been trying their best to guard that secret, but who knows how long this secret can be kept?

Once Yi's life experience is revealed, that heroic and dry hero will really be remembered for 10,000 years.

Cheng Biting Jin was silent for a long time, and Zong Xiu sighed: "That's it, my brother doesn't want to say it, and I don't ask." Rest assured, I have decided to change her freedom and will not change my words. ”

Cheng Yanjin got up solemnly, hugged his fists and said: "Don't worry, brother Xian, you have this mind in your heart according to Lao Cheng, if that mantra can't exchange for Yi Yatou's freedom, and provoke His Majesty to punish you, brother, I will fight for my life to keep you safe." ”

"Haha, I'm relieved to have my brother's words."

The corners of Zong Xiu's mouth outlined a hint of a smile.

Cheng Yanjin thought for a while, and suddenly asked again: "Brother, don't blame me for being too talkative, why did your temperament change so quickly?" ”

Zong Xiu endured the pain, gritted his teeth and said, "Thanks to my brother's order, I figured it out." If you come to Chang'an, you will be safe, and if you are lucky enough to go to Chang'an in this life, if you are tied, what is the difference between it and the original? ”

The more Zong Xiu spoke, the more excited he became, and a whip whipped him awake.

Yes, I was fortunate enough to travel to Chang'an, and I was still afraid everywhere, is this worthy of the crossing arranged by God?

Looking at Cui Xianwen, he has no merit and fame, but he can make a lot of nonsense at the roasted tail banquet, and Lao Li has to take care of his feelings.

It can be seen that fame is sometimes a means of self-preservation.

When you have enough fame, even if the emperor wants to move you, you have to weigh it.

At the end, Zong Xiu patted the bed board excitedly: "Life is a lifetime, grass and trees are autumn!" To do something, I have to do the biggest thing, I want to do the wind and wind, I want to turn the world upside down, I want the world to chant my name - really show! ”

The hysterical screams were almost crazy, and Zong Xiu's words were vague, Cheng Biting Jin only thought that Zong Xiu had been whipped, and he was angry, and he didn't intervene, so he should listen to it.

The two chatted for a while, and a craftsman walked in, holding a new type of abacus made according to Zong Xiu's description, and said, "Lu Gong, Gongzi, it's done." The villain is in a hurry, and he didn't bring a tung oil or anything, you take a look, if you don't take advantage of it, the small one will make another one, and the color of the tung oil will be better. ”

Cheng Yanjin stepped forward quickly and took it in his hand.

This is made by a carpenter, the new abacus depicted by Zong Xiu, the carpenter is the fastest, and there is no need to build a mold first, like blacksmiths and goldsmiths, and then pour iron and gold juice to shape it.

Cheng Biting Jin swayed up and down, and said strangely: "Brother Xian, come quickly, what is the formula?" ”

Zong Xiu smiled: "Don't worry, don't worry, when everything is done, I will write the simple mantra on paper, and you will send it to the palace." ”

The people invited by Cheng Yanjin are all famous craftsmen in Chang'an, with quick hands and feet, and exquisite workmanship.

Because the new abacus depicted by Zong Xiu is too simple and easy to do, it is not difficult for them, and it will take less than half an hour from the start of work to the end of work.

After the three identical new abacus of wood, iron, and gold were made, Zong Xiu asked Cheng Biting Jin to write it on his behalf, and he dictated and wrote the simplest addition and subtraction operation formula, and asked Cheng Biting Jin to enter the palace quickly.

When Cheng Yanjin rushed to Daming Palace with his servants and dozens of finished products in large bags and small packages, the noon dynasty had dispersed, Lao Li was chatting with a few old buddies, and even the queen's eldest grandson Wujian was also beside him.

"Your Majesty, Your Majesty, great joy, great joy."

Before Cheng Biting Jin entered the main hall, he shouted first.

Wei Chi Jingde coaxed: "What, didn't Lu Gongmo ask for a small room again, and he was happy?" ”

"Go, go, I'll get down to business."

Li Shimin couldn't help but ridicule: "When will Zhijie have something to do?" ”

Cheng Yanjin left the servant outside the palace, carried a big bag into the hall, threw the burden on the ground, sang a promise with a smile, and said: "Your Majesty, I am here to offer treasure for my younger brother I just recognized." ”

"Zong Xiu?" Lao Li remembered what happened last night, and frowned slightly: "What does the sect assistant want to offer?" ”

The eldest grandson Wujian also said: "I'm afraid it's not a whip, and if you have a good memory, Duke Lu is here to beg for mercy for him." ”

"Niangniang laughed, Brother Zong really has a treasure to offer, but he said that this treasure is not given in vain, he wants to ask His Majesty for someone."

Lest Lao Li and the eldest grandson Wujian misunderstand, Cheng Yanjin explained: "Don't worry, it's definitely not Princess Lanling." ”

The emperor doesn't like bargaining courtiers, Lao Li's eyes narrowed slightly: "Who is he going to ask for from me?" ”

Cheng Yanjin snorted: "Your Majesty, as for who he wants to behold, let me sell it first." Wait for you and Niangniang to finish reading this treasure, if it is pertinent, I will talk about who that person is. ”

"You guy." Li Shimin scolded with a smile and said, "Then take out the treasure, I want to see what treasure he can offer." ”

"Gotcha."

Cheng Biting Jin untied the burden, revealing dozens of rectangular bodies with thin sticks in the middle and beads strung on them.

"This ......" the eldest grandson Wujian looked at it and said, "Duke Lu, this is also a treasure?" ”

Originally, the eldest grandson Wujian thought that Cheng Yanjin wanted to intercede for Zong Xiu and take out some treasure from his own treasure house.

But what is this pile of chic calculations in front of you?

Li Shiji, Wei Zheng, and Fang Xuanling came over curiously, and one of them picked up a pair: "Lu Gong, this is the happy event in your mouth?" ”

Cheng Biting Jin pretended to be mysterious and said, "This is called a new type of abacus!" It is a treasure of arithmetic improved by my brother Zongxian, and with his formula, it can replace arithmetic chips, and can calculate complex algorithms at the fastest speed. ”

"A new type of abacus?"

Lao Li, the eldest grandson Wujian and the ministers are all confused, but they have also learned abacus, which is obscure and cumbersome, and it is better to calculate and be practical.

Cheng Yanjin picked up a gold abacus in his hand, shook it in his hand, and the abacus beads 'banged': "Old Fang, let me ask you, when the treasury is liquidated every year, all the account books are calculated with calculations, how long does it take?" ”

Fang Xuanling thought for a while and said, "It's a month if it's fast, and it's possible to be three or five months if it's slow." ”

"Then if you use the abacus and add my virtuous brother's mantra, it will only take three days, can you believe it?"

"It's impossible!" Fang Xuanling retorted.

Wei Zheng casually dialed the abacus in his hand and said slowly: "I am a little convinced that Zong Xiu can create numbers and formulas, and has unique attainments along with arithmetic. Zhijie, don't sell it, let's talk about it, what is the formula? ”

Lao Li and the eldest grandson Wujian were also aroused, and they all looked at Cheng Yanjin.

In the limelight, Cheng Yanjin took out the mantra written by Zong Xiu from his arms and said, "Your Majesty, this is the mantra, simple and easy to understand, you might as well give it a try." ”

Wei Zheng grabbed the paper and opened it to see that in addition to the formula, there were also some test questions from Zong Xiu, and he tried it according to the formula, and it was really fast.

"This ...... Your Majesty, this is really an amazing treasure, and the sect assistant is really a genius in arithmetic. ”

Wei Zheng can achieve the position of prime minister, and his mind is naturally smart, although he has not used an abacus for a long time, and he is a little rusty again, but he also looks like it.

When the ministers saw that the abacus was moved, they all gathered around to see the piece of paper.

Lao Li coughed lightly, and everyone hurriedly dispersed, Chai Shao grabbed the paper with a smile, and took two gold abacus and handed them to Lao Li and his wife.

Lao Li didn't look at it either, and said: "Since it can be recognized by Wei Xiang, it must be a treasure, let's discuss it together." ”

After speaking, Lao Li ordered the guards to bring the flower stand, and Chu Suiliang transcribed the note.

After a stick of incense, Lao Li, the eldest grandson Wuji, Li Shiji, Wei Zheng, Fang Xuanling, the eldest grandson Wuji, Chai Shao, Wei Chi Jingde and others in the Daming Palace all had a pair of abacus, and dialed the abacus according to the mantra transcribed by Zhu Suiliang.

The sound of the abacus went from being jerky at the beginning to crackling at the end, and everyone became more and more skillful.

From the addition and subtraction of small numbers to the addition and subtraction of huge amounts, everyone seems to be addicted.

It wasn't until it got dark that Lao Li raised his head and said, "Zhijie, why is there only addition and subtraction, not multiplication and division?" ”

Cheng Yanjin's face changed slightly, and he quickly squeezed out a smile.

"Your Majesty, my virtuous brother is a real person, he has recently become obsessed with a girl, and he is worried that His Majesty will not let him go, so he deliberately kept a hand. Brother Zong said that if His Majesty is willing to release people, he will naturally give the multiplication and elimination formula, and if His Majesty is unwilling, he is also willing to hand over the following formula, but ......"
