County government office, chief clerk's room.

Niu Qiqing and Yang Yuan sat together with tea, glanced at Wu Ji's table, which was filled with account books, two thick stacks, which were particularly conspicuous.

The two looked at each other and smiled, drank tea, and started talking, and looked down upon them.

"You said, will he come today?" Niu Qiqing took a sip of tea and asked calmly.

He had no answer at all when he heard his tone. He had already contained the answer.

"I guess he won't come." Yang Yuan smiled proudly and pointed to two stacks of account books: "That's a thick account book, not to mention three days, just ten days. I'm still talking about whether it can be completed!"

Just as the two were discussing, Huangfu Song, who was sitting aside and drinking tea on his own, moved his ears, raised his eyebrows slightly, and a playful smile appeared on the corner of his mouth. He glanced at Niu and Yang and returned to silence again.

"Bang! Bang!"

The footsteps sounded, and the land fell very lightly, and they were very weak. This was Wu Ji's footsteps. Wu Ji was so tired that he was very weak when he walked.

"Here you come!" Niu Qiqing was a little surprised. He had just expected that Wu Ji would not come.

"What can I have to do if I come?" Yang Yuan didn't care at all, and he cracked his lips: "Isn't it embarrassing to see you!"

"Who is talking bad about me behind my back?" Wu Ji's voice sounded, and he plunged in, his eyes swept over Niu and Yang, which was quite interesting.

"I'll just talk about you!" Niu Qiqing was really awesome as his surname. He raised his neck and chest and said proudly: "If you can't settle the accounts, you have to get out. Isn't that embarrassing?"

"Niu Qiqing, I'll give you a piece of advice. Don't do things too well. If you say too much, you're asking for trouble!" Wu Ji's eyes condensed on Niu Qiqing and said coldly.

"Haha!" Niu Qiqing seemed to hear the most ridiculous thing in the world, looked up at the sky and laughed: "Have you said too much, you will know in three days. Yesterday was not counted, so you have nothing to say, and you will be convinced by the loss!"

"There is no need to wait until three days later, and there will be a conclusion today!" Wu Ji was full of confidence and came to the table, put the abacus on the table, and sat down.

Huangfu Song originally looked like an ancient well, his eyes were fixed on the abacus, and his brows were tilted again, and he was quite surprised. His eyes kept looking at the abacus, showing a thoughtful look, but he didn't say anything.

"What can you do if you make a broken thing?" Yang Yuan didn't care at all, and then laughed at Wu Ji.

Wu Ji ignored them, took a account book, flipped it open, flipped the account book with his left hand and pulled the calculation beads with his right hand, making a "pa" sound, which was particularly crisp and beautiful.

"It's mysterious!" Niu Qiqing pulled the corners of his mouth and drank tea leisurely.

Yang Yuan even saved even more of his words.

Wu Ji flipped through the account book page by page, and kept pulling the beads with his right hand. The sound of "pa" was crisp and continuous. For a moment, the whole house was filled with the sound of beads.

Huangfu Song's eyes flashed with a splendor, like a sharp sword, and it disappeared in one flash. Wu Ji buried his head in settlement, but he did not notice it.

Wu Ji finished a thick account book without much effort. He picked up a brush, dipped it ink, wrote down the numbers on the account book, and put it aside.

Huangfu Song stood up, came close to him, picked up the account book, and looked through it. After turning a few pages, he showed a deep thought, thought for a moment, picked up the calculation sheet, and kept fiddling with it, fiddling with it while fiddling with it.

Niu Yang and the others saw it and couldn't help but smile contemptuously, sitting and drinking their tea, without caring about it.

Wu Ji shook his hand, took another account book, flipped the account book with his left hand, and pulled the calculation beads with his right hand. This time, the calculation beads were pulled faster, with constant noise and compactness. This is why Wu Ji became more and more skillful as he used it.

Modern people, except for those old antiques, use either calculator or computer, who can use abacus? Therefore, although Wu Ji knew it, he had not used it for many years and some of them were born. As he had more calculations, he became more and more proficient. He pulled up the abacus beads with his right hand and moved quickly.

Huangfu Song stopped the calculations in his hand, looked at Wu Ji for a while, and his eyes showed a look of surprise, a little unbelievable.

Niu Yang and the others were a little confused when they saw Wu Ji so focused. Niu Qiqing lowered his voice and asked, "Did he be a pretentious person or how many times did he really do?"

Yang Yuan looked at Wu Ji, but he was still unsure of his mind: "Are you going to be mysterious? Maybe, maybe, you should... how many times?"

The two stood up, came to Huangfu Song, lowered their voices, and asked, "Mr. Huangfu, how about it?" The two seemed a little afraid of Huangfu Song, their tone was extremely respectful, and their figure was lowered.

"Can't you calculate it yourself?" Huangfu Song gave the two a blank look, and the light flashed in his eyes.

The two seemed to have done something wrong, so they quickly lowered their heads and did not dare to look at Huangfu Song's eyes, as if they were dodging their eyes. The two wanted to find a account to settle, but they saw that Wu Ji had not finished the calculation yet, so they wanted to calculate with Huangfu Song, and then rolled their eyes, which scared them to speak. For a moment, the two of them were not human.

Fortunately, Wu Ji didn't have much effort to calculate the second book, so he picked up the pen and wrote the numbers on it, put it aside. The two hurriedly grabbed it, returned to their seats, picked up the calculation sheet, and started to calculate.

"Bao! Bao!"

The crisp sound of beads kept ringing, as dense as fried beans. Listening to such a tight sound of beads, Niu and Yang became more and more shocked and could not control it. They tried their best to settle the accounts.

Huangfu Song kept fiddling with the calculation of the funds, and it took a lot of effort to finish the calculation. Looking at the numbers on the account, he couldn't help but look surprised, and an unbelievable look appeared in his eyes. He turned his head and looked at Wu Ji, and saw that there were four more calculated accounts on Wu Ji's desk, which means that Wu Ji's efficiency was five times that of him.

This was too unbelievable. Huangfu Song stared at Wu Ji, his eyes flashing: "Mr. Wu, have you learned it long ago?"

"Why did it happen?" Wu Ji stopped, raised his head, and found that Huangfu Song had changed. He was full of energy and was filled with a strong aura. He was completely different from Huangfu Song before, and he couldn't help but be surprised.

"Although this thing has appeared for some time, it can only perform addition and subtraction operations, but cannot perform multiplication and division. Imperial College..." Huangfu Song seemed to realize that he missed his mouth and quickly changed the topic: "It is said that if you are proficient in this thing, it is not worse than mental arithmetic!"

"Isn't it worse than mental arithmetic?" Niu Yang and his two surprised voices rang, their faces very ugly.

"Although the way of mental arithmetic is great, there are too few people like that, and there may not be one out of a million. However, if you learn this thing well, even ordinary people have the ability to mental arithmetic!" Huangfu Song looked surprised and kept looking at Wu Ji.

"This..." Niu Yang and the others realized that they seemed to have kicked the iron plate, and sweat oozed out of their foreheads.

"Who taught you?" Huangfu Song asked in anticipation.

"Does it need to be taught such a simple thing?" Wu Ji shook his head. Wu Ji found some materials on the Internet, bought abacus, and then learned it.

"Simple?" Huangfu Song's eyes widened, his chin almost hit the table.

Abacus has been around for a while, but it can only perform simple addition and subtraction operations, but cannot perform multiplication and division operations. Therefore, it has not been popular yet and belongs to the research stage. In Huangfu Song's eyes, people who are skilled in using Wu Ji are the masters among the masters, and they are no longer as high as possible.

Wu Ji's light words actually shocked Huangfu Song half to death!

"Is it okay?" Wu Ji saw Huangfu Song's shock in his eyes, and felt a little funny.

In modern society, things that appear in the Song Dynasty were all extraordinary events, and they were enough to shock the great scholars and scare this little chief clerk. It is naturally no problem.

I kept calculating, and the sound of the calculation beads resounded throughout the house.

"Mr. Huangfu, is the result correct?" Niu Qiqing suppressed his fear and asked quietly.

"Do it yourself!" Huangfu Song replied in anger, picked up another account book, fiddled with the calculation of the plan, and then started to calculate.

Niu Qi's face was so cold that he felt very uncomfortable. He couldn't afford to offend Huangfu Song, so he had to go back and continue to calculate with Yang Yuan.

The two of them looked at Wu Ji from time to time, and saw Wu Ji one by one for a while, as if it was not a thick account book, but a small thing, and it was not difficult at all. The more they read it, the more they were more and more frightened, and the feeling of the bad feeling became stronger and stronger.

"Are you confused?" When the two of them finished calculating, Wu Ji's calculation was extremely correct, and he couldn't help but be foolish. He could only attribute this result to Wu Ji's confusion.

"You guys are confused and try it!" Wu Ji was in no mood to pay attention to them at all. Huangfu Song picked up several calculated account books and put them in front of the two: "All these are right! Can you be completely confused?"

"..." The two of them opened their mouths and wanted to speak, but they couldn't find the words to speak.

The three of them used all their strength and were sweating profusely, but Wu Ji was extremely relaxed, as if he was strolling in the garden, without any tension. When the three of them calculated less than one-third, Wu Ji pushed the abacus and breathed out: "It's over! It's over!"

"Is this over?" Although Huangfu Song knew that the abacus was very powerful and comparable to the mental abacus technique, he was still very surprised.

"This..." Niu Yang and his two teeth grinded their teeth, their faces were extremely ugly, and they all turned blue!
Chapter completed!
