Ying Baoyue stood at the foot of the battle platform, looking at the disciple who was called after her but had already stepped onto the battle platform.

This kind of high-profile occasion is usually nervous for young children, but the young boy surnamed Du has a calm expression. Standing on the stage and looking at her condescendingly, her still childish face was a little disapproving.

and disdain for her.

"What? Is the former Qin princess afraid? If you want to hurry up, don't let the master wait, the master still has a Taoist problem that has not been solved! Du Siqi shouted.

Technique...... Title?

Ying Baoyue was stunned when she heard this, and looked at the cute and strange little boy on the battle platform.

She has seen a lot of weirdos in her past and present lives, but this is the first time she has met such a child.

"What is he talking about?" Ying Baoyue looked at Chen Zichu, "What does the problem mean?" ”

Chen Zichu was also stunned when she heard the words of the girl next to her, but she didn't expect that on such an occasion, she not only didn't get angry when she heard the clamor of this little boy, but she cared about these things for the first time.

However, as a son of a family, he did hear of Du Siqi's strange behavior.

"Look at where he was standing," Chen Zichu said, "it should be at his feet." ”

Ying Baoyue looked over, and then on the ground where Du Siqi was originally standing, he saw a lot of ...... Geometry.

Triangular, rectangular, trapezoidal, fan-shaped...... are densely carved on the mud ground with tree branches, and in an instant, Ying hugged the moon soul and returned to the math class before the college entrance examination.

She looked at the young man on the high platform, and no wonder she had noticed at first glance that it was not his face, but the dirt on the placket of his chest.

In her mind, she suddenly remembered the picture of the other people practicing on the stage just now, but the little boy was lying on the ground and drawing geometric figures.

It turned out that she didn't see him not only because of his height, but because he was lying on the ground all the time......

Although she had seen such a person in modern times in her previous life, she had never seen it on the Shanhai Continent, let alone seen it in the family.

As the heir of the Du family, who is also known as the two great families of Southern Chu and the Ye family, this sister-in-law's interest ...... It's really special, too.

You must know that the family has always paid attention to the cultivation of appearances and poetry, literature and scriptures, and the calculation of academic mathematics is regarded as a strange skill, and there are few people who learn, fewer people who are interested, and fewer people who understand.

At this time, Guichen beside Ying Baoyue followed her gaze to the dirt and frowned, "What are these?" Ghost Draw Charms? ”

"It's all stuff from the Shuyuan, and I don't know," Chen Zichu said.

Although it was not the first time he had seen it, Chen Zichu did not know what Du Siqi had painted. The six arts of the gentleman, etiquette, music, archery, royalty, calligraphy, and mathematics, although there are "numbers", but the number ranks last, and has always been the least valued by the family.

The average family can understand an account book and not be deceived by others, but for the family, these are mundane things, and it is not beneficial to be more involved.

After all, they are not craftsmen and pariahs, and the children of the family are proficient in arithmetic, but in the calculation of quantity and money, no one will look at those strange graphics, let alone study what Du Siqi hangs on his lips all day long. ”

Ying Baoyue listened to the words of the two family sons around her who really didn't know, looked at Ni Di's strange figure in the eyes of others and said quietly, "This is Fang Tian." ”

"Fang Tian?" Guichen was stunned and repeated.

"The first chapter of "Nine Chapters of Counting", the chapter is called Fang Tian. The drawings on this ground are all the figures that appear in the chapter of Fang Tian. Ying Baoyue explained.

As we all know, "Nine Chapters of Arithmetic" is divided into nine chapters, so it is called nine chapters of arithmetic, and the first chapter is "Fang Tian," which mainly describes the calculation method of the area of plane geometric figures.

A total of eight methods for calculating the area of the figure include rectangle, isosceles triangle, right-angle trapezoid, isosceles trapezoid, circle, fan, bow, and circle. In addition, the four rules of operation of fractions and the methods of finding the greatest common divisor of the numerator and denominator are systematically described.

She has already chosen a statement that people in this world can understand, but Guichen should have been kicked out of the homecoming mansion to read the "Pharmacopoeia", and many people in the family did not have the opportunity to read the required reading.

"Is it really nine chapters of arithmetic?" Chen Zichu had a headache and said, as the most famous book in arithmetic, of course he knew the name of this book, but he only skimmed it over and did not study it deeply.

It's just that even the sons who often go out to socialize and talk to others don't read this book, why does the princess in front of her, who should only learn needlework in the deep palace, look like she has read this book?

Even Zhao Guang, who was healing with his eyes closed, opened his eyes and looked at him in surprise when he heard this.

"What the hell are you ......" However, before Chen Zichu could ask this sentence, the examiner's impatient voice came from the battle platform.

"Former Qin princess, come to power quickly, otherwise it will be considered as giving up this battle!"

"I have to go," Ying Baoyue stretched out her hand to Guichen beside her, the two snapped high-fives, she looked at the worried teenagers behind her and smiled, "I'm on!" ”

After saying that, she didn't look back, and strode onto the stage of her first battle.

The two people fighting each other were standing still on the stage, but the expressions of the people and cultivators who were watching the two figures from the high stage were quite complicated.

"What kind of weird pairing is this," Jiang Yuanyuan looked at the two tall and short figures on the stage, and his expression was a little subtle, "If these two people are not cultivators, they can probably only be described as old and weak women and children." ”

"A young child and a woman, what kind of battle is this......"

The people under the high stage whispered.

"This Du family son is also a freak...... A good young genius is not obsessed with what arithmetic ......"

"Two freaks, who will win......"

"Du Gongzi's talent is one of the best, after all, at the age of twelve, he became the sixth rank, if Meng Jizi didn't participate this time, he would say that this person can reproduce the demeanor of Chunhuajun and win the top!"

Twelve-year-old rank six?

Guichen in the audience widened his eyes when he heard this, "Is this person ......?"

"Before the age of ten, Du Siqi was a famous genius in the mainland," Zhao Guang opened his eyes and said lightly, "At that time, people said that he was the most talented prodigy on the mainland after Shao Si Ming Lin Baoyue. ”

"Following that young master...... "It's really hard to imagine that boy with perverse manners would be such a powerful person, and Guichen was like being in an ice cellar when he heard this.

If it weren't for the fact that he went to the math academy to learn mathematics later, with Du Siqi's talent, he might be no less famous than Ji Jiashu now.

Chen Zichu's eyes were slightly cold on the side.

But even if the reputation is not there, Du Siqi's strength is also first-class. His record is not as good as Ji Jiashu because he is obsessed with arithmetic and does not participate in any screening of the Jixia School Palace, but if there is no problem with his memory, Chen Zichu remembers it very clearly.

"I remember ......"

Chen Zichu took a deep breath.

"Du Siqi has been undefeated in the battle with the sons of the same realm families, except for Jiashu and Siyuan."

and Ji Jiashu because Ji Jiashu's realm is higher than him, and Ye Siyuan because Ye Siyuan said that Ye Du's two families are not in harmony and resolutely do not compare with this little boy.

Guichen was speechless when he heard this, and he only looked at the figure of Ying Baoyue on the high platform, only full of worry.

However, the tension in the audience did not reach the stage.

Ying Baoyue stood still on the battle platform under the urging of the examiner, but found that although the examiner was urging her, Du Siqi, who had been urging her to come to the stage before, was silent from just now.

The young black bean's eyes watched her walk up in silence, and after she stood still, he suddenly spoke, "You also know Fang Tian?" Know nine chapters of arithmetic? ”

"I know a little bit about it," Ying Baoyue said with a glance up at him.

Although she was dressed in, she was a liberal arts student in her previous life, and her best subject was not mathematics, so she didn't want to make a mistake in front of people who really loved it.

However, her words didn't know which nerve of this genius boy was stimulated, and Du Siqi's round face instantly turned cold when he heard this.

"Sure enough, how can a woman understand this." The little boy sneered, "It's a shameless person who doesn't know how to pretend to know how to do arithmetic and pretend to be erudite." ”

With two swishes, he drew his sword from its sheath and spoke proudly, "Draw your sword and attack." ”

"A mere seventh-rank cultivator," Du Siqi sneered, "let me chop you up." ”
