Time passed quietly, and a slight rustling sound suddenly sounded under the door, Wu Suyan slowly stood up, walked over gently, and saw a piece of paper slowly stuffed under the crack in the door, only to see that it was written: "Sister, pi can no longer be calculated, it is an infinite and endless decimal place, even if it is calculated to the end of life, it will not see the end." ”

Further down is the formula for calculating the area and perimeter of a circle.

Thinking of the cautious appearance of the leaves behind the door, a smile appeared on Wu Suyan's face, and all the embarrassing entanglements disappeared in an instant, "The little pervert is a younger brother, I am a sister, if the little pervert is cranky and talking nonsense, I will clean him up!"

A gentle knock sounded on the door, and Wu Suyan knew that this was a signal to inform herself, and it was also a signal that Ye Zi was leaving.

Wu Suyan suddenly pulled the door open, revealing Ye Zi, who had turned around and was about to leave with a panicked face, and grabbed Ye Zi's ears with lightning speed, "Little pervert, look where you are running this time!"

I really have a way to die, Ye Zi cried with a sad face, and was obediently pulled into the room by Wu Suyan.

"What did you see tonight?" Wu Suyan asked with a smile.

Ye Zi heard the strings and knew the elegant meaning, and he didn't know how to answer: "I didn't see anything!"

"What do you hear?"

"Didn't hear anything!"

Wu Suyan was very satisfied with Ye Zi's upper words, and the hand holding Ye Zi's ears relaxed, "You didn't see anything tonight, you didn't hear anything, did you?"

Ye Zi nodded again and again like a chicken pecking rice, "I didn't see anything, I didn't hear anything!"

Wu Suyan let go of Ye Zi's ears and patted the top of Ye Zi's head, "What a good child!"

Ye Zichang breathed a sigh of relief, it seems that this matter is in the past.

Wu Suyan also secretly breathed a sigh of relief, looked at the paper stuffed under the crack of the leaf delivery door and asked, "What is the infinite and endless decimal place of pi?"

"I don't know why!"

For Wu Suyan's question, Ye Zi could only smile bitterly, he could know the calculation method of pi because the particularly knowledgeable teacher had said it when he was in school, in fact, even so, it has been forgotten for many years, but after crossing over, many things that have been forgotten and vague will be vividly remembered as long as they are touched and remembered.

"I can only tell my sister that the person who told me how to calculate pi said this, and that the Taoist instrument that has the ability to calculate is not inferior to the nine-turn abacus has not calculated the result. ”

Ye Zi believed that the computing power of the computer would not be lost to the abacus of the ninth turn, and the computer did not calculate the result.

"Is that so!" Wu Suyan said regretfully, although she had given up halfway, but with the opportunity, she still hoped to draw a successful end to her years of research, but this kind of pi cannot.

Seeing Wu Suyan's regret, a bright smile appeared on Ye Zi's face, "Sister, there is no perfect thing in the world, maybe it is because of this that the world is so gorgeous and colorful." And as long as there is a trade-off, we can get the calculation results that meet our needs, so why should we force too much and ask for trouble, sister, don't you say?"

Wu Suyan looked at Ye Zi in amazement, although she had already realized that this was a young master, she was still surprised by such philosophical words.

"The little pervert can say such a reasonable thing, it's really surprising to my sister!" Wu Suyan rubbed Ye Zi's head vigorously, venting her frustration that she actually needed a child's enlightenment.

"Sister, didn't nothing happen tonight?" Ye Zi protested, he hadn't done anything, how could he bear such an indishonorable title.

Wu Suyanqiao's face turned slightly red, and she said angrily: "Nothing has happened, but my sister said that if you say that Xiao Seliang is a little pervert!"

Ye Zi didn't dare to be angry, nor did he dare to speak, so he could only label Wu Suyan in his heart: Lafayette!

Mozhu lay quietly on the table, Wu Suyan walked over and sat down on the chair, and then she had to calculate the area and circumference of the circle, and when the calculation was completed, Mozhu's promotion would be completed, and her years of research would come to a complete end.

First, take out a short rope and draw a standard circle, measure the radius, and start calculating.

The calculation of the perimeter and area was completed successively, the ink beads made a joyful vibrating, and the abacus beads beat happily and made a crisp and pleasant sound, which is Wu Suyan's emotion at the moment, and the ink beads present it, but it is also the emotion of the ink beads.

The lotus master became friends with the immortals and became friends, and the Taoist instruments were one.

In the pleasant sound of the collision of abacus, the dark black of the ink beads becomes more and more warm and deep, which is the sublimation of the material. The sublimation speed of the Dao artifact material should be slow and imperceptible, but at this moment, it is a speed that can be detected by the naked eye, which is a phenomenon that can only be brought about by the great growth of the Dao artifact's spirituality.

The sublimation of the material was finally completed, Wu Suyan put away the ink beads, looked at the leaf excitedly, and hugged the leaf tightly in her arms, "Brother, thank you!"

The head is buried between the round and soft twin peaks, and the silkiness of the skin can be clearly felt through the thin clothes, but the leaves of such a beautiful blessing can't stand it, and they complain in their hearts**: "Sister, how did you learn my master's methods!"

But at this time, he didn't do anything to push Wu Suyan away, so Ye Zi had to muttered in his heart that coloring is empty and coloring, so as to calm the spurting blood.

The excitement slowly calmed down, Wu Suyan let go of the leaves and said again: "Brother, thank you!"

Finally relieved, Ye Zi let out a long breath, and felt sincerely happy for Wu Suyan, "Isn't it right for my brother to help my sister, besides, only if my sister is powerful, my younger brother can be a fox and a tiger, and he can be domineering and bullying men and women, right?"

The fox is pretending to be a tiger, bullying men and women, and being domineering, Wu Suyan almost held her breath and didn't catch her breath, can't this little bastard speak normally?

Knocking on the head of the leaf with a chestnut, Wu Suyan raised her face and said fiercely: "Speak to me well!"

"I'm talking well!"

Ye Zi rubbed his head with grievances on his face, "Money has to be spent to be valuable, if it is piled up at home, it can only be regarded as a pile of good-looking metal." In the same way, if my sister becomes a powerful Lotus Master, of course I have to go out and show it, otherwise who will know that I have a strong sister.

When the time comes, I will take a folding fan, write on it 'My sister is Wu Suyan', and take Xiaohua to beat Gong Xuan first, that guy owes me four dolls and has not delivered them so far, and then snatches Qing'er back to pay off the debt......"

It turned out to be such a fox and a fake tiger, rampant and domineering, bullying men and women!

Looking at a serious leaf, thinking of the fan that said "My sister is Wu Suyan", Wu Suyan couldn't help laughing anymore, holding her stomach and laughing, the flower branches trembling, completely forgetting the reserve of women.

Finally stopped laughing, Wu Suyan breathlessly said, "You little bastard, laugh at me......"

"Sister should laugh more!" Ye Zi smiled brightly, and couldn't resist the tiredness of yawning, "Sister, rest early, I'll go to bed too!"

"No!" Wu Suyan categorically vetoed, "I said that I want to get drunk with my sister today, do you want to deny it?"

Her desire to drink now is stronger than before, but it is no longer because of depression, but because she is happy: she has solved the math problems she has studied for many years, the abnormal mentality that has been bothering her for a long time has finally been eliminated, the ink beads have not only completed the sublimation of the material, but also grown spiritually, and more importantly, the bad brother has made her very happy.

Wu Suyan was happy, and Ye Zi was also happy for Wu Suyan, cheering up, "Okay, I'll drink with my sister!"

"You go get the wine, I'll go to the kitchen and prepare something to eat!" Wu So-yeon assigned the task.

Not long after, Wu Suyan had prepared a few side dishes to accompany the wine, and Ye Zi also brought back a jar of wine, and the two of them drank it in a staggered manner, and soon they were drunk.

Wu Suyan drank a glass of wine again, and suddenly thought of the Dao Weapon that she had never seen a leaf before, "Brother, although the cultivation of the source of the Heavenly Phenomena and the cultivation of Baolian are the foundation of the Lotus Master, and you have also become acquainted with Xiaohua and Jin'er, but the cultivation of Dao Instruments is still important, you must not slack off!"

"Sister, don't worry, how can a genius like me not cultivate the Dao weapon, it's just that I can't take it out yet, and when I can take it out, it will frighten many people a little.

My Taoist weapon is a dragon fishing rod!" Ye Zi said triumphantly, he would lose his words when he was drunk, but the more important reason was that he trusted Wu Suyan.

"It turned out to be a fishing rod!" Wu Suyan laughed happily, "No matter how good the name is, it's also a fishing rod, brother, you don't have to be shy, there's nothing wrong with being a fisherman, maybe you really have a chance to catch a dragon in the future." ”

"It's a real dragon fishing rod......" Ye Zi was about to explain, when the wine came to his head, and he was already lying on the table and drunk.
