The next day, nothing happened.

Going to class, eating, going to work, gnawing on the dregs of medicine.

The three-dimensional value of the harvest was 0.5, the strength increased by 1600 kg, and the "meaning" did not change.

……

On the third day, nothing happened.

Go to class, eat in a big bite, go to work, and munch on the dregs of medicine.

The three-dimensional value of the harvest was 0.6, the strength increased by 1920 kg, and the "meaning" did not change.

……

On the fourth day, it was sunny, the morning dawned, and the sunlight broke through the clouds, like a brilliant golden pillar, obliquely inserted between heaven and earth.

"Today's sunshine is a bit dazzling!"

"Mmmm, Brother Yan is so literate!"

The duo of Yan Xing and Raymond, as usual, walked towards the academy with dewdrops, and halfway through the walk, they heard a fierce commotion in front of them.

A group of teenage outer disciples formed a group on the periphery of the school, three layers inside and three layers outside, and a few children in the middle spoke fiercely, fighting for each other.

"Humph! You are a mud leg, and you are more knowledgeable than me? Do you understand the speed at which light travels? Do you know the nature of the formation of the Great Day? Joke! You know it's a big ball of fire! ”

"What else to say, the sun is very big today, red, like a red persimmon, I'm illiterate!"

"You ......"

The child who was dumbfounded was still an acquaintance, it was the girl in the green dress who had seen Yan Xing gone, and her little face was red with anger at the moment, and she couldn't speak with her fingers outstretched.

"Don't change the subject!"

"What we're talking about is whether the westernmost people can see the same sun when the sun rises in the east of the continent, or if it should be the sun in 200 billion years, and we are bathed in the same sun?"

This realm is a round place, so the only thing that hinders the propagation of light is distance, and when everyone knows the infinite vastness of the continent under their feet, they have some thoughts about some daily phenomena, and this is why there is this debate about the sun.

Wow, two children arguing about the day?

Yan Xing's expression moved slightly, and he walked out of the crowd in a few steps, looked at the children whose faces were as red as the sun, and then looked up at the bright golden sun in the void, and was puzzled in his heart.

It has been a while since his memory awakened, and through a series of phenomena, he found that many physical constants in this world are no different from those in his previous life, such as the propagation speed of sound and light, magnetic permeability, gravitational constant, etc., and he has to suspect that the four basic forces of the universe in the two worlds are connected.

From this, if light travels at that "slow" speed, how does it manage to shine in the face of something as magnificent as the infinite continent, which spans 200 billion light years?

Moreover, there is also the sunrise in the east, and the four seasons change, which is even more unreasonable.

"Let's just say you're a mud leg, I once flipped through ancient books in the clan library, and I saw a description of the Great Day from them."

"It is said that in the opening up of each realm, there is a great power to penetrate into the void and bring a great sun to hang in the sky, so ah, what all beings on our infinite continent see is not the same sun!"

Yan Xing nodded slightly when he heard this, it seemed a little reasonable, but ......

"Giggles, a world for a day? Our Meteoric Realm is not very big on the mainland, but the east and west also span ten trillion kilometers, and it takes a year to run alone, so how can we achieve such a synchronization of time and day, day and night? ”

"This, this ......"

The other party was speechless, and the girl in the green dress pulled back a city, proudly clasping her hands on her waist. Yan Xing's brows furrowed slightly, what he was wondering about was this, he lacked a lot of extraordinary knowledge, and he couldn't even understand the most common phenomena.

"It's time for morning recitation, what are you still doing here?"

A burly man passed by here, saw the noise outside the school, and came over to scold.

"Ah, I've seen Mr. Lu!"

Everyone bowed, Lu Tiexian, one of the elders of the inner gate, was their teacher of a brief history of civilization, and also served as nature, biology, geography, analysis of surrounding forces, etc., everything could be related to two sentences.

"Mr. Lu, we are discussing the ...... of the sun"

"Oh?"

Lu Tiexian understood the beginning and the end, and sighed in his heart, it turned out that it was because of Lord Ethereal Lingzi, these things were not originally something that outer disciples needed to know, and now, he could only incorporate them into the curriculum.

"Let's go to the morning recitation first, and I'll explain this question to you in class after breakfast."

After that, Lu Tiexian stepped out in one step, turned into an afterimage and disappeared, for the next explanation, he needed to go back to the inner door cave to get a prop.

Hey, I just wanted to earn some contribution points, but I didn't expect it to be so troublesome, and I will never take this kind of errand with children in the future.

After the morning recitation, the Great Stomach King Yan Xing was full of firepower, and directly swallowed the blood food of a hundred people, and no one dared to approach it within a radius of ten zhang. Those who read the joke and mocked him for being a red-haired pig have changed their eyes.

"Brother Wang, this ...... There's something wrong with this guy! ”

"Humph! Do you want you to say it? Lao Tzu is not blind! ”

He is not stupid, he understands how much benefit it will be to the flesh if so much blood food is digested and absorbed, and in the long run, the strength of this mud leg must not surpass him?

Wang Li's expression was ruthless, and he secretly decided in his heart that he couldn't let Yan Xing continue like this.

Clang! Bell –

"Yes, my strength has increased a lot."

Yan Xing wiped his mouth, nodded with satisfaction, got up and walked towards the school, mainly because the meal time was limited, otherwise he could eat more.

"All here?"

On the high platform, Lu Tiexian stood with his hands in his hands, scanning below with a majestic gaze, he is now a teacher, and he has to look like a teacher.

"I've met Mr. Lu! Good morning, teacher! ”

"Well, sit down."

"Today's Topic - Day!"

Lu Tiexian stretched out a finger and wrote the word "day" in the void with a point of light as a stroke, and then the word "day" exploded, and countless points of light shrank together violently, turning into a round of burning sun.

Yan Xing was amazed to see it, this teaching method was both intuitive and interesting, and it immediately attracted the attention of all the children.

"The sun shines and the light shines on the world, which is one of the main ways for all spirits to obtain energy."

"Especially for ordinary beings, they cannot absorb the aura of heaven and earth, they can only obtain energy from plants and beasts, brute beasts, brute beasts hunt wild beasts, wild beasts eat plants, and plants thrive in the sun......"

"From this, a complete food chain is formed."

"Before you take off your mortal body, you are also in this food chain, and after you achieve transcendence, there will be more choices, eating and drinking dew, and carrying aura, which are just basic operations."

Lu Tiexian paused, then waved the fireball in front of him, and with a movement of his mind, he took out something from the storage bracelet and placed it on the high platform.

This means of taking things out of thin air, so that a group of children are hot, storage treasures, expensive, the most important thing is that it needs extraordinary power to drive, it is said that after the promotion of the inner door, the cave will be equipped with one for each person.

Yan Xing didn't feel anything about this, his left eye was infected by the essence of the Monkey Phoenix, and the deep pupils mutated and evolved into a hell dimension, the space is huge, it can suppress the enemy, and it can also store things, so naturally he can't look down on this ordinary little bracelet.

"Okay, after talking about the importance of the Great Day, I will now tell you about how the Great Day of our world exists and how it works."

After that, Lu Tiexian pinched the trick in his hand and lightly tapped it on the cone in front of him, and on its smooth surface, dense inscriptions suddenly appeared, slowly hanging in the air.

The solid cone becomes transparent, and its interior is divided into layers after layer, except for the bottom part, which is still solid, the upper half is transparent and formless, and the bottom of the cone also spews gray mist, forming a short cone that twists and irregularly.

"Teacher Lu, what is this?"

Everyone couldn't see it, so they couldn't help but ask in a low voice.

"To know how the Great Sun exists and works, you first need to have some understanding of the dimensions, this gadget, called [Material World and Thirteen Dimensions Simulator]."

"Look!"

Lu Tiexian stretched out his hand and pointed at it, and actually inserted the cone, dotting on the only entity on the bottom of the cone, and there was a round of light masks above and below it, which together formed a flat ellipsoid.

"This is the world we live in, that is, the material world, where ninety percent of the origin is concentrated, and there is time to run through the past and the present and the future, so it is also called the four-dimensional world."

"Underneath the material world, this short twisted cone, are three-dimensional, two-dimensional, one-dimensional, and zero-dimensional worlds, which are collectively called low-dimensional worlds."

"Above the material world, five to thirteen dimensions, is the high-dimensional world."

"And the great sun, which you can see every day, is here......"

Lu Tiexian moved his finger and pressed it on the top of the cone, on the small pointed tip.

"Thirteen Dimensional Worlds."

"Huh!?"

Although they didn't understand anything, they didn't know why, they always felt that what Mr. Lu said was very awesome and very lofty.

"Huh, ahhh

"The infinite continent spans nearly 200 billion light years, and the light transmission of the great sun is still a trivial matter. Just move more! ”

Lu Tiexian spoke very quickly, his voice was full of emotion, and the corners of Yan Xing's mouth, who was listening seriously, twitched, knowing that this guy was going off topic again, but it was okay, you could learn more about the secret knowledge.

"In ancient times, there was a realm, because of the power of the hand, formed a scene of ninety-nine days at the same time, the earth was scorched to the ground, and finally it was my human race who took a shot, took a bow and arrows, and shot down ninety rounds of the sun, avoiding a catastrophe ......"

"So the Great Day is just a small thing, the infinite continent is huge and immense, what really restricts the development of civilization, the exchange and communication between various places, is hindered by the boundless distance, which is also the reason for the emergence of the chaotic ancient era!"

"Why is the Age of Troubles called the Dark Ages? Because at that time, the sheltered places of the various realms were independent of each other due to the closed transmission of information, like walking in the dark forest, whoever exposed the location first could attract the siege and hunt of the surrounding realms. ”

"The chaos of ancient darkness lasted for 98.1 billion years, until the alliance of the nine major races established the [Supreme Council], and the first organization formed after the establishment of this council was the [Time and Space Dimension Administration], well, right here, the headquarters of the Authority is in the thirteenth dimensional world."

"Ahem, let's get back to what you care about."

Lu Tiexian's expression froze, coughed lightly twice, and then focused on the tip of the cone with his fingers, and said in a condensed voice: "Looking down on the low dimension from the high dimension, there is no spatial distance, and in conceptual understanding, the two are overlapping points and points. ”

"Therefore, with the [Space-Time Dimension Administration] as a transit hub, information exchange and cross-border passage are no longer obstacles, and if you can afford to pay the price, you can cross it in one step!"

"Since then, the communication between civilizations has been unhindered, ending the dark and turbulent ancient era, stepping into the ancient void colonization era, and the nine major races have driven out the other races under the control of the [Supreme Council] and shared the infinite continent."

Syllable!

Lu Tiexian snapped his fingers, and a little glimmer of light fell on the tip of the cone, like a big sun, and the rays of light crossed the layers of dimensions, shining in the material world, and at the same time, not missing a corner.

"The Great Sun is just an accessory after the end of the war, and the [Supreme Council] placed the Great Sun in the Thirteen Dimensional Worlds for the unity of civilization."

"Of course, the transmission of light is solved by the dimension, but the conservation of energy remains the same, and a great sun feeds an infinite continent spanning two hundred billion light years at the same time, and the consumption is very terrifying, and it needs to replenish 'fuel' at all times, which is under the jurisdiction of a special organization [Nichiji]."

"I'm done, do you understand?"

Lu Tiexian breathed a sigh of relief, waved his hand to retract the cone, and everyone below nodded again and again, and the two children who debated the day also lowered their heads in shame, they were too ignorant.

Wonderful! Perfect!

Fair and reasonable!

Yan Xing's emotions were stirred, and his heart's perception of the extraordinary was refreshed again, and its powerful and majestic place surpassed ordinary imagination.

But now, he's hungry.

It's time for lunch.

Class!
