- Because of the limited time, when everyone saw Yi Wen put on that position, although they had doubts in their hearts, no one spoke at this time.

And when Yi Wen officially started calculus, as long as the viewer could distinguish his desktop with his eyes, they were all even more surprised. An abacus has two areas, upper and lower, and two abacus side by side, there are four vertical areas, but there are still only two areas used by Yi Wen.

After observing intently for a moment, Shi Yi understood that Yi Wen was using this method to save the five beads carrying. In this way, the numbers only need to be carried once when they are stacked to ten beads.

This kind of algorithm, in operation, is clumsy and rigid, similar to when a child is learning to count, the brain is not enough to think about superposition, so use a small stick or stone to replace the number, in the most intuitive way to calculate addition and subtraction.

Shi Yi suddenly remembered a scene. In his previous life, many children used to use a wrench to calculate addition and subtraction within ten digits when they first learned mathematics. This method is slow, but it is accurate.

In order to persuade the students to get used to thinking more with their brains, the teacher often said with a straight face: Now you only need to calculate addition and subtraction within ten digits, and you can barely make up with ten fingers. By the time you start to learn addition and subtraction of hundreds, that is, taking off your shoes and adding your toes, it will not be enough.

Shi Yi looked at Yi Wen in front of him again, his algorithm was like a primary school student, as if he didn't want to use his brain, but Shi Yi would not despise him at all because of this, because he could see that Yi Wen was saving time for mental thinking and using it to improve his speed.

This statement may seem contradictory, but it can work for someone who is confident that they can finger quickly.

At this moment, Yi Wen's subordinates no longer seemed to be dialing the abacus beads that represented the numbers, he was more like pushing the grain with a hand rake, and the numbers in the account book were for him. It seems that it no longer needs to go through the brain, and it is printed directly on the abacus.

What made Shi Yi grind his teeth the most was his speed.

At this time, he still didn't use the multi-fingering method of the Ya name Fulan finger, but the ring fingering method that Shi Yi joked about before, moving his thumb and index finger up and down. His hand, in an instant, seemed to have become the needle of an electrochemical sewing machine. Click......

That's the speed at which you're going crazy!

Shi Yi watched Yi Wen's fingers move when they were already slightly connected with each other, and he couldn't help but swallow a mouthful of saliva.

In the judging position on the opposite side. Ruan Luo saw that Yi Wen still didn't use his finger, and felt a little regretful in his heart, and at the same time a little surprised.

At this time, he could no longer see the steps of Yi Wen's activities as clearly as he did at the beginning of the game. Although Yi Wen's finger speed is fast, the back of his hand is extremely stable, and only the knuckles of his fingers are moving, and staring at his hand for a long time seems to make people feel scratched in their hearts.

I have to say. With such a snap of his fingers and fluency in calculations, Yi Wen could indeed show confidence and only use one-fifth of the time he counted the first time of the account book to calculate it again.

Seeing the scene in front of him, the two-person arena that was originally prepared has become a one-person performance stage, and it is obvious that there is no need to supervise the cheating problem. In addition, his eyesight could no longer keep up with the other party's finger speed, so Ruan Luo did not stare at Yi Wen anymore and withdrew his gaze. He picked up the teacup on the table at hand.

But he had just lifted the lid of the teacup when he suddenly heard a voice from behind him: Brother Ruan, you forgot again!

Ruan Luo's hand holding the teacup couldn't help but tremble slightly, and he was about to look sideways, when Mo Ye, who had been standing behind him, had already walked in front of him. And stretched out his hand.

Ruan Luo understood and closed the lid. Hand out the teacup.

Mo Ye took the teacup and was about to turn around and leave to change the tea, but she only took two steps, turned around and looked back, and couldn't help but say: Xiaoyi, he ...... Is it really wrong?

Ruan Luo understood what she really wanted to ask, but he really hadn't read the answer, and he didn't want to be perfunctory, so after pondering for a while, he only gave a more neutral answer: Wait, maybe when Yi Wen finishes the calculation again, the answer will be revealed.

Mo Ye nodded, didn't ask anything more, and turned to leave. Ruan Luo could feel from her back and footsteps that she usually walked as briskly as the wind, but at this time, there was a slight stagnation in her steps.

Is she worried about Shi Yi's defeat, or does she not want me to replace Shi Yi in the competition? Ruan Luo, who was looking at Mo Ye's back, was in a mood that floated for a moment.

When he retracted his gaze and sat upright, Yan Yu on the side suddenly smiled and said: I didn't expect her quiet temperament to have such a powerful side.

Of course, the word "powerful" that Yan Yu said does not have a derogatory meaning. It was not difficult for Ruan Luo to understand this, probably Yan Yu was laughing with him again.

Glancing sideways at the table where the tea cup had been put just now, Ruan Luo said with a smile: She has persuaded me several times and told me not to drink cold tea, but I am often negligent because of this. No matter how good-tempered a person is, he should be impatient when he encounters someone like me.

Yan Yu shook her head slightly: You just don't know how to take care of yourself, it has nothing to do with character. I'm curious how your sister-in-law got married to you. Even if you take care of you so much, the two of you can be so clearly separated.

She was...... Ruan Luo's words had just opened two words, and he suddenly realized Wang Zhe's identity, and after a little hesitation, he only said simply: I ask a friend to help me and introduce her to stay with me.

That's not ...... Yan Yu was surprised, but before he could say the word maid at the end of his words, he heard a noise outside Dongfeng Tower, and it seemed that someone was rudely banging on the door, interrupting the conversation between Yan Yu and Ruan Luo.

Yan Yu couldn't help frowning slightly, he was tired of the feeling of being suddenly disturbed, but there was no way, Dongfeng Building was not his territory, someone outside wanted to come in, it would not be like when he was at the Yan Family Chamber of Commerce, someone could communicate to him in advance.

However, the attendants he brought with him were well aware of his temper, and it only took one look for two of them to stand up, apparently going out to 'reason' with the man who was knocking on the door.

But at this moment, among the several red girls of Dongfeng Lou who were sitting together on the other side, there was also a person who stood up. She looked much younger than the others, and she was still roughly a girl, and her face was even colder without a gentle smile due to her purple clothes.

Seeing this, Yan Yu's pupils moved slightly.

Before he came to Dongfeng Tower, he didn't inquire about the details of this famous golden building in Nanzhao Emperor's capital, although he hadn't been able to completely find out who the real owner of this building was, but his understanding of this woman in purple was clear and detailed than that of the people in other buildings-
