Before Zhou You and Xu Tianling could walk back to the dormitory building, wonton smelled the smell of adventure and came out of nowhere. After seeing Zhou You's expression, he confirmed the matter even more.

"It's too cunning to ask me for adventure." Willon bulged his mouth and opened his question.

"This time is not an adventure, it is an investigation, you don't understand." Zhou You waved his hand and said, "Don't make trouble."

"I understand. Tian Ling and I have inspected many times. We have to ask for bodyguards when we inspect. Have you not watched "Grave Robbers' Chronicles"? We have to do it sooner or later." Willon took the form of the Celestial Extinction of the Celestial One, "At this time, the store manager needs a gold medal bodyguard, the Great Chaos."

Zhou You looked at her, then after facing Xu Tianling's expression, he lowered his head and walked away fiercely.

"Hey, hey, can I fight if I don't speak?" Willon forcedly followed Zhou You's thigh, as comfortable as a little koala.

Zhou You's mind was full of π at this time, and he didn't throw her away, so he just walked into the dormitory building quickly.

As soon as I entered the hall, I ran into Su Yiyi, who was carrying a bunch of ingredients downstairs. Su Yiyi realized something when she saw their expressions. She lowered her head with a sad expression: "Oh... Those who work are always working silently and swayingly, can only spend the whole life. This is probably my destiny... They are always serving others... burning themselves..."

"Do it! It's not a trip, it's a scientific investigation, it's very boring." Zhou You cursed.

"I... just want to see the outside world..." Su Yiyi covered her face and wiped her tears, "It's okay, store manager, I am a staff member who deserves diligence in your heart. Go and play, I will continue to work... Silently marginalized, becoming an optional background... I grow old sadly and buried in another township..."

Zhou You was so angry that he said, "Come on! Come on, too, okay."

"Oye!" Su Yiyi instantly threw away the food bag and squeezed into the team, leaned over and pulled wonton, "Where to go, where to go?"

"Be serious." Wanton turned back and scolded seriously, "What are you doing?"

"You get down first, don't hold my legs."

"No! Xu Tianling always lied to me, and last time he suddenly invited me to eat durian cakes and slipped away by himself."

"Then you hug it a little bit, it's very itchy."

"Where is itchy? I'll scratch it for you."

“…”

Zhou You first went to the utility room, took a pair of plastic ropes that tied things, and took a few round plates. Then he went to his office to get some stationery, and then the group entered the secret room in a noisy way and started making reference objects together.

He first took a piece of plastic rope and surrounded the plate to make sure that it would be surrounded for a whole week and then cut it off. Then he visually measured a center of the circle and cut off a piece of rope equivalent to the radius of the circle.

Although the operation is not very standardized and the tools are simple, there must be errors, after measuring with a ruler, their proportional relationship basically meets the pi, and the error will not exceed two millimeters.

Then, they made three sets of ropes with three plates with radii of 8cm, 10cm and 12cm. Each set of ropes is one long and one short, the long one is the circumference and the short one is the radius.

After measurement, the radius of 8cm corresponds to the circumference of 50cm, 10 corresponds to 68, and 12 corresponds to 75, which undoubtedly satisfy the pi.

Wonton looked at Zhou You like a fool: "The circumference is equal to 2πr, I know this, what are you doing with such serious verification by the store manager?"

Xu Tianling looked at Willon with a little begging: "Be a good bodyguard, don't use your brain."

"It doesn't matter, the change of pi is something that we can't understand. We are all equally naive about this." Zhou You wiped his sweat, carefully arranged the three sets of ropes, and arranged the three sets of circles and radii, which were very visually consistent. "It's impossible to be wrong... If pi changes, the definition of the circle will change, and it can't be a circle... right, Tianling?"

Xu Tianling only shook his head: "I don't know, I'll talk about it after seeing it."

She said and turned to Su Yiyi again: "You are from the spiritual plane, right? Do you have pi?"

"I haven't heard of it. We are all thoughtful and there is no physical object in the sense of the earth." Su Yiyi still shook her head after working hard, "I can't explain clearly, I'm not even sure whether there is a concept of circle in the pan-spirit plane."

"I don't want to do it anymore, go to the actual test first." Zhou You took out his phone and started operating, "Go to the Yuling Plane first."

...

It took a long time since I came here, the Yuling Plant has become a large crop factory. There are seven or eight workers from where I don’t know where they come from. Some are busy in the field and some are sleeping. Because the Yuling Plant has an eternal and comfortable climate, it does not require a house to shelter from the wind and rain. If you hadn’t seen a familiar tree, you would have thought you had accidentally entered a large farmland with a fertile soil in heaven.

"Why did it happen like this?" Zhou You turned his head and looked at Su Yiyi.

"Don't ask me, they did it." Su Yiyi pointed to Xu Tianling. The so-called "them" could only be Leng Xie.

Xu Tianling made a hip-hop gesture and changed the topic stiffly. "Quick test Pi yoo."

"No, this cannot be mixed up. You can explain first. What happened during this period of time? "

"Simply put,..." Xu Tianling chose to continue hip-hop, "yoo~~ The Yuling plane planted crops, and the area of ​​whatever you planted is large. The yield per acre of beef is 18,000, and you will no longer need to import it. You can earn fish balls!"

“…”

Seeing that Zhou You's expression changed, Xu Tianling knew that he didn't like this music style, so he quickly ended: "yeah~~Don't worry, don't worry, the fish balls are all managers!"

"For the sake of your hard work," Zhou You shook his head, and immediately took out the plate and watched first.

Several people also watched hard around the plate, up, down, left, left, right, front, back and back.

"Is it round?" Zhou You swallowed and spitted.

"It must be." Su Yiyi nodded.

"There are slight errors in mathematics, but they do not affect our judgment." Xu Tianling also returned to the state of seriousness.

"Do you have any pitfalls in your mind?" At this time, it was normal that wonton was the only one. She looked at the rest of the people like a psychopath, "What kind of unintelligent investigation is this?"

Zhou You ignored her, breathed a sigh of relief, put the plate with a radius of 8cm on the ground, then picked up the rope corresponding to its circumference and surrounded it bit by bit.

Zhou You looked very nervous.

This 50-centimeter-long plastic rope has never been so sacred. If the pi changes, the rope will not be able to surround the plate. This will become the strangest thing he has ever encountered in his life. Although it is just a simple number, the shock is far beyond the magic war.

The last small piece of rope was almost trembling and surrounded.

The beginning and the end are just in line.

"Hu..." Zhou You sat down on the ground and breathed a sigh of relief, "I just said...How could the pi change?"
Chapter completed!
