Pi, a constant in mathematics, is a mystery that has led to the search for the limits of this number.

Although for people, pi is an irrational number, that is, an infinite number without cyclic decimals, and it is impossible to calculate to its end, many people believe that as long as pi is accurate enough, then human beings will be able to solve the mysteries of the universe.

Pi is found in the famous pyramid, and the circumference of the base of the Great Pyramid divided by twice the height of the tower is Pi.

And as long as pi exists, then it is impossible for humans to calculate the exact area of a circle, because π exists as an infinite non-cyclic decimal, which is an unknown value, which means that it will always exist in a seemingly random sequence.

It is true that the Mayan civilization was centuries ahead of humanity in terms of numbers and astronomy, but in the eyes of people, a civilization that could not even cast bronze and iron, how could they engage in such an ethereal and meaningless thing.

The Mayans are most famous for their prophecies, and the first four prophecies have come true, the first to the fourth civilization all perished under the Maya prophecy, only the fifth civilization, according to the AD calendar, December 31, 2012, is the end of the fifth civilization, but it seems that nothing happened at that time.

Planck shook his head, and the more he thought about these things, the more he found that his mind became more and more chaotic, more and more unable to stop, and fell into a logical loop. The Mayan civilization has always been shrouded in a veil of mystery that is impossible to see.

Planck took a deep breath and stumbled upon a polygonal circle above his head, in which a regular hexagon was cut.

"Inscribed polygon..."

For a moment, Planck's mind exploded with a wave.

"Cut pi!" Inspiration flashed through Planck's mind.

One of the algorithms for pi, the circumcision method, is to draw a regular hexagon attached to a circle, and by multiplying the number of sides of the inscribed polygon, he found that its perimeter will get closer and closer to the circumference.

The method is to make a regular triangle in the circle first, and divide the three-segmented arc into bisecting points to obtain a regular hexagon, similar to a regular dodecagon, until it is a regular 3 times 2^n polygon, with its circumference to approximate the circumference of the circle, divided by the diameter is pi.

Planck looked around at the scene and smiled, following the starting point of the polygon above his head, Planck noticed that all but two of the stone statues were not in their original positions, and the others were in the same position as the fresco on top.

Planck came to the two statues, pushed the statues hard, and the statues were rubbed by Planck little by little, and after half an hour of busy work, Planck finally restored the two statues to their original positions perfectly.

At the moment of restoration, Planck could feel the entire lookout tremble, the dome at the top opened, and a golden ray of sunlight shone through the dome, like the light of the myth and legend when mortals ascended to heaven.

Planck hesitated, but decided to stand in the middle of the sun, looking up, it was a round of glowing sun in the sky, Planck for a moment his consciousness suddenly blurred, and then his body suddenly lost weightless, and there was a big pit under him, and he fell into it.

The cavern's passage was so narrow that Planck bumped into it, wounded himself, and finally fell into the water, his consciousness suddenly sinking, and his body slowly sinking.

......

"Hey, David, thank you for some durian rice wings!" The boys and girls wore T-shirts and started a BBQ in the field, they took local materials, burned wood into charcoal, and then put the barbecue on the iron rack.

"Okay Jack, I don't know how you would want to eat such a disgusting thing, it tastes worse than the cheese I've been sitting on for a long time!" David handed the durian wings to a boy with a look of disgust.

"Don't say that, David, believe me, you're guaranteed to love the taste when you take a bite, it's like an ugly orange, it looks ugly, but only those who have eaten it know it's sweet!" Jack took a bite and smiled brightly.

"I'd rather fall in love with my fermented cheese than try it! it smells worse than those stinking 'eggs of the century,' like roasted!" David retched a few times as he stuck out his tongue.

"David, don't say that, everyone has no appetite for what you're doing, let's hurry up and eat more while Team Leader Planck hasn't come back yet!"

"Team Leader Planck isn't a funny guy!" David rolled his eyes, Planck was an academic nerd, unpopular with the club-minded, open-minded House of Eden, he was too rigid and a machine.

"Don't you think the team leader has been gone for a long time?

"Okay Jack, don't cry there and fake mercy, your smile is written on your damn face, it's so hypocritical!

"But the team leader has been gone for a long time!" said one girl, a little worried.

"Could it be that Team Leader Planck is having a meeting with the Mayans right now, discussing how the sacrifice will take place tonight and tomorrow?" Jack looked unconcerned.

"No work!" One boy tried to contact Planck, but the other party kept showing no signal.

"How come? I'll try!" David also snorted, and just like the boy just now, a gust of wind blew, and everyone suddenly shuddered.

Planck's communication has no signal, so there are only two conclusions, one is that he has turned off the communication service now, such a possibility is almost non-existent, all students know that the communication must be turned on all the time when performing the mission, then there is only one case.

"The patriarch shouldn't have entered a space with a powerful ability disturbance!" a girl's face turned pale, and everyone knows how big an ability disturbance it takes to block the communication.

"No... It's unlikely!" Jack's face changed dramatically, and Planck was really in a shielded space now?

"Ask Adam, if Adam can't even see the location of the team leader, I think this matter is a bit serious!" David sent Adam the location information, and the target was Planck.

"I'm sorry, we have lost Planck's location coordinates here, but please be patient, Planck has a lot of experience in performing tasks, and he will definitely try to contact us!" Adam's phantom appeared in front of everyone's eyes.

Roar......

In the jungle in the distance, several strange beasts suddenly sprang out of the dense rainforest, rushing towards everyone, and everyone panicked for a while.

"Get the weapons!" shouted David, not believing that the beasts had come for their roast, their hideous appearance had already made their identities known.

These students are some sophomores, and they originally came here to accompany Planck to mix up some credits or something, and by the way, they traveled here for three days, but who knew that this kind of thing would happen on the first day.

Bang bang bang......

The weapons in everyone's hands shot towards the running Strange Beasts, and the Strange Beasts fell to the ground in response, and the kinetic energy of their bodies slid on the gravel with their corpses, but a flying Strange Beast poured out of the sky, and black shadows floated back and forth between the heavens and the earth, and the faces of the young people changed greatly.

"Fast forward to the armored car!" shouted David.

Everyone crowded into the armored car, and in a hurry, a girl's foot broke and she threw herself on the ground, "Help... Help!"

"Karen!" Jack shouted, but he didn't want to save the flying beasts outside, which included mutated giant mosquitoes, birds of prey and winged lizards, which he couldn't deal with.

"I'll go! you cover me!" David dropped his two pistols and rushed towards Karen, and everyone used their lame marksmanship to shoot at the Alien Beast in the air, the Alien Beast flew very fast, and was about to pounce on Karen, and Jack shot it off in the head.

“nice shoot！”

David shouted, "Come on, Karen, cheer up!" he put Karen's arm on his shoulder, and the two limped towards the armored car.

"Another one!" cried Jack, his pistol running out of bullets, this time both of them were more than lucky.

"Chain of Gods-Cyclone!"

David looked back at the flying Beast behind him, and activated his own chain of gods, the cyclone, which was able to disturb the surrounding air pressure for a short time, causing a violent wind, and with the help of the cyclone, the Beast was blown into the air.

"You come here to help her, I can't last long here!" David used his two hands together, activating the chain of gods, his body was trembling and hot, he could feel the water in his body evaporating rapidly, and the chain of gods in the range was extremely consumed.

Jack ran over and gave Karen a hand, and the two ran back into the armored car, and Jack shouted, "Come back!"

David severed his connection to the Chain of Gods and ran backwards, but the Beasts had been accumulating potential energy for a long time, and they were twice as fast as they had just since the relative force of the wind had been removed.

"Oh no!" Jack watched as David was about to be pounced on by a huge bird of prey, which swooped down like an eagle catching a chicken.

piu......

A ray of white particles pierced through the raptor's head and fell behind David, black pus flowing from his body.

"It's Team Morgan!"

Jack shouted, tears of excitement coming out of his eyes, they would be saved when they came to their side.

Posey took the alchemy weapon and shot at the Alien Beast in the air, he was an extremely accurate marksman, and with the firepower of the ground team, a large number of barrages poured down, and quickly dispersed the flying Alien Beast here.

Morgan's team ran through the corpse-strewn rubble and toward the armored vehicle.

"Are you all right?" Morgan asked, running up to the group of students.

"It's okay, thank you..."David gasped, a cold sweat broke out on his back.

"Where's your leader?" Morgan asked, looking at the crowd.

"Team Leader... The team leader is lost," Jack muttered.

"Lost?" Morgan and Percy looked at each other, a little confused.

......

"Wake up, my child!"

"Aren't you looking for the truth? this is the world of truth!"

"Come, throw yourself into the arms of God!"

Prang opened his eyes, and around him was a hazy underwater world.

These three words always echoed in his mind, and he slowly swam to the surface of the water, the cold groundwater made his body feel extremely cold, but the temperature on the water surface was high, it was simply a strange appearance of ice and fire.

There is a lot of space here, and the stone walls above are dotted with crystals, twinkling and twinkling like stars in a summer night, and there are all kinds of stone statues around the stone walls, and they hold flames in their hands, and those flames seem to burn in their hands out of thin air, which is incredible.

The world here can only be described in four words, "There is no cave!"
