Before Zhou You and Void Heavenly Spirit walked back to the dormitory building, Wanton smelled the smell of exploration, and he didn't know where to get out, and after seeing Zhou You's expression, he confirmed the matter even more.

"Expeditions don't call me, it's too cunning. Wonton puffed out and asked.

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

"I know, I've been with the Heavenly Spirit many times. You have to have bodyguards for the investigation, haven't you read "Notes on Tomb Robbery"? "Wanton put up a Cangsheng Silence Accumulation Style, "At this time, the store manager needs a gold medal plane bodyguard, Great Chaos." ”

Zhou You looked at her, and then after exchanging expressions with the Void Heavenly Spirit, he lowered his head and walked away at the same time.

"Hey, hey, it's okay if I don't talk and fight. Wonton forcibly followed and hugged Zhou You's thighs, as comfortable as a little koala.

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

As soon as I entered the hall, I bumped into Su Yiyi, who was carrying a bunch of ingredients downstairs, Su Yiyi realized something when she saw their expressions, and lowered her head gloomily: "Alas...... Those who work are always paying silently, swaggering, and can spend all day drinking, this is probably my fate...... Always in service to others...... Burn yourself ......"

"Oh yes, it's not a trip, it's a scientific expedition, it's boring. Zhou You scolded.

"I ...... I just want to see the outside world......" Su Yiyi hid her face and wiped her tears, "It's okay, store manager, I am a diligent staff in your heart." Go play, I'll get on with my work...... Silent marginalization becomes a dispensable background...... Old and buried in another country......"

You traveled for a while, and his head was big: "Come on, come on, come too, okay." ”

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

"Be serious. Wonton looked back and scolded matter-of-factly, "Investigate." ”

"You come down for me first, don't hold my legs. ”

"No! The Void Heavenly Spirit always lied to me, 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's the itch? I'll scratch it for you. ”

“……”

Zhou You first went to the utility room, took a handful of plastic ropes to bundle things, took a few round plates, and then went to his office to get some stationery.

He first took a piece of plastic rope, encircled the plate, made sure that it was cut after a full week, and then visually inspected the center of a circle to cut a piece of rope equivalent to the radius of the circle.

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

Next, they made three sets of ropes with three plates with a radius of 8cm, 10cm and 12cm, each set of rope is one long and one short, the long one is the circumference and the short one is the radius.

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

Wanton looked at Zhou You like a fool: "The circumference is equal to 2πR, I know this Wow, what are you doing so seriously verifying?"

The Void Heavenly Spirit looked at Wanton a little pleadingly: "Be a good bodyguard, don't use your brains." ”

"It doesn't matter, the change in pi is something that none of us can understand, and we are all equally naïve about it. Zhou You wiped his sweat, carefully arranged the three sets of ropes, and laid out three sets of circles and radii, which were very visually consistent, "There can be no mistake...... If pi changes, then the definition of a circle changes, and it can't be a circle...... Right, Celestial?"

Void Heavenly Spirit only shook his head: "I don't know, I'll talk about it after seeing it." ”

She said and turned to look at Su Yiyi: "You are from the pan-spiritual plane, right, do you have pi?"

"Haven't heard of it. We are all distracted, and there is no physical object in the sense of the earth. Su Yiyi still shook her head after some effort, "I can't tell, I'm not even sure if there is such a concept as a circle in the pan-animatic plane." ”

"I don't want to, let's go to the actual test first. Zhou You took out his mobile phone and began to operate, "Go to the Yu Ling plane first." ”

……

I haven't been here for a long time, the Yu Ling Plane has become a large crop factory, there are seven or eight workers in the field who don't know where they come from, some are busy in the field, some are sleeping, because the Yu Ling Plane has an eternal and comfortable climate, and there is no need for a house to shelter from the wind and rain, if you don't see a familiar tree, you will think that you have strayed into a large farmland with a god-given fertile soil.

"How did this happen?" Zhou You turned his head to look at Su Yiyi.

"Don't ask me, they did. Su Yiyi pointed to the Void Heavenly Spirit, the so-called "they", and the other can only be cold and evil.

The Void Heavenly Spirit made a hip-hop gesture and changed the subject stiffly. "Quick measurement of pi Yoo. ”

"No, this can't be mixed up, you explain first, I don't care what happened during this time?"

"To put it simply, it's ......" Xu Tianling chose to continue hip-hop, "Yoo~~ Yu Ling's plane grows crops, what is planted is a large area, the yield of beef per mu is 18,000, there is no need to import it anymore, fish balls are earning a lot!"

“……”

Seeing that Zhou You's expression had changed, Xutian Ling knew that he didn't like this genre, so he hurriedly finished: "yes~~ Don't worry, don't worry, the fish balls are all store managers!"

"For your sake. Zhou You shook his head, and immediately took out the plate to watch first.

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

"It's round, right?" Zhou You swallowed and foamed.

"It has to be. Su Yiyi nodded.

"There was a slight error in the mathemat, but it didn't affect our judgment. "The Void Heavenly Spirit has also returned to a serious state.

"Do you all have a hole in your brain?" At this time, only Wonton was normal, and she looked at the rest of the people like a neurotic, "What kind of out-of-the-way investigation is this?"

Zhou You ignored her, took a deep breath, put the plate with a radius of 8cm on the ground, and then picked up the rope corresponding to its circumference and surrounded it little by little.

Zhou You's expression was very nervous.

This 50-centimeter-long plastic rope has never been so sacred, if the pi is changed, this rope will not be able to just enclose the plate, this incident will become the weirdest thing he has ever encountered in his life, although it is only a simple number, but the shock is far greater than the magic war.

The last small piece of rope was almost finished trembling around the tour.

From beginning to end, just right.

"Huh......" Zhou You sat on the ground and breathed a sigh of relief, "I'll just say it...... How could pi change. ”

Wonton leaned over to Su Yiyi's side and whispered, "Is he so serious? Is it because of my brain problem or does he have a problem?"
