Time changes the hour to hours, minutes, seconds, milliseconds, lengths to feet, inches to kilometers, meters, centimeters, millimeters, weights to pounds, two, pounds, baht to tons, kilograms (kilograms), grams, milligrams, and acres to acres, divided into square kilometers, square meters, square centimeters......

Starting from the most basic time, length, weight, area, and volume, all the way to the newly added density, volume, angle, force, hardness, torque, etc., and finally ending with the food gas measurement, Qin Yu spent a full day and a night before finally finishing the reform of weights and measures.

During the period, there was no one to go to the toilet, everyone was listening attentively and remembering carefully, trying to understand and digest, and not daring to slack off.

Because this reform of weights and measures was recognized by all the saints, all the saints of the thirteen kingdoms gathered to hold the edict of the world, obviously preparing to implement the reform system as soon as possible, so the sooner you adapt, the better, and through the explanation of Qin Yu, the founder, it is undoubtedly the best opportunity to adapt.

After the explanation, Jixia Food Palace sent food and wine, everyone took a break and began to enter the question session, everyone only had one chance to ask questions, so that Qin Yu could answer questions.

"Actually, I don't understand how the twelve hours are divided, why are they divided like this, and now that they are going to be changed to twenty-four hours, can you explain to me why?" asked a food emperor in the United States.

Qin Yu condensed the ball of light with food qi and drew an orbit in the air: "Actually, it's very simple, look at the land where we are located as a round ball, the ball revolves around the sun for a year, and a circle around itself is a day, as for why it is divided into twenty-four hours, because ......"

Before he finished speaking, the crowd suddenly stirred, and most of the people had a look of disbelief in their eyes, and the Mi Guo Food Emperor who asked the question was stunned: "What are you talking about? The land under our feet is round? This is impossible, if it is round, how can we stand firm?"

Another food emperor said: "And the sun, obviously the sun revolves around us, why do we revolve around the sun? We are the center!"

Everyone bowed their heads in agreement, obviously struggling with these two questions, in their understanding, the sky is round and flat, the sun rises in the east and sets in the west, naturally the sun should revolve around the food continent.

Qin Yu vomited blood, and actually forgot about this stubble, didn't the world he came to in ancient times also think that the sky was round? Copernicus was also burned to death because of heliocentrism, cough cough, although Copernicus was actually one-sided, but we must not forget the sacrifice he made for the truth......

Uh, it's far away, the brain hole is retracted, Qin Yu sighed, it seems that he has to give this group of guys in the ancient timeline a good science popularization, otherwise how can he be worthy of the elementary school teacher in that world?

"Everyone, maybe you will be unhappy to say this, but in fact, you are all wrong!" Qin Yu raised his voice and shook the audience.

The commotion of the crowd gradually quieted down, looking at Qin Yu with suspicious eyes, wanting to hear why Qin Yu said they were wrong.

"First of all, we must make sure that the earth under our feet is round, not square, flat, and the reason why it looks flat is because we are so small, and with the undulating mountains and houses, it is almost impossible for us to distinguish the curvature of the ground. Qin Yu said in a loud voice.

"Since you can't tell the difference, what evidence do you have that the earth is spherical?" asked a certain food venerable of the Qi Kingdom solemnly, everything is about evidence, if Qin Yu didn't have evidence, he would definitely not believe it.

Qin Yu said: "Of course, there are many big foods from coastal countries, you must have experienced such a thing, standing on the beach and looking at the sea, obviously there are no ships on the horizon, but as the ships sail to the coast, you will first see the top of the sail, then the middle of the sail, and finally the whole ship." ”

Hearing this, almost all the big eaters from the coastal countries silently bowed their heads in thought, they had indeed seen such a scene, but they never thought about why it was.

If the ground is flat, the ocean is of course flat, and theoretically no matter how far away we are, we can see the whole ship as far as we can see it, why do the ships gradually appear in our field of vision? ”

"In the same way, the earth under our feet is also part of the sphere, and the land and the sea form a huge sphere, and if you start from a point and run after the sun, you will eventually come back to where you are, because you have run around the sphere. On the other hand, if the ground is flat, you chase and chase and run into the void, have you ever seen such a thing? If you don't believe me, you can fly around and try it, and I guarantee you'll come back in the opposite direction. ”

Seeing that Qin Yu's tone was so confident, and what he said was indeed very reasonable, everyone talked about it, and some of them were really eager to try.

"Don't worry, it's not too late to try again after the edict is over. Qin Yu smiled dumbly, pointed to the condensed ball of light and orbit, and continued, "The second question is who revolves around whom, the spatial scope involved is too large to be explained, and it involves the problem of the frame of reference. In short, the rising and setting of the sun in the east and in the west is the result of the autobiography of the earth beneath our feet, the moon that surrounds us, and the other spheres, revolve around the sun, and the sun revolves around another core, as the saints can attest. ”

Everyone looked up at the saints, and the majestic voice of the head of the saints sounded: "That's right!"

The audience was in an uproar, it turned out that the earth under their feet was really round, it was a sphere, not the sun revolving around the food continent, but the food continent revolving around the sun, which in turn showed that the food continent is not the center of the endless void, the food continent is not special, and it is not the only darling of the big world!

The long-standing common sense has been completely subverted, and when this news of the affirmation of the saints spreads, it can be imagined how much waves it will cause, and the entire food continent will struggle to shake in the change of wrong and right.

Qingyi looked at Qin Yu blankly, and suddenly felt that Qin Yu's figure was a little taller, as if even the background had turned into an endless void of billions of stars.

"Silly girl......" Huo Sheng looked at Qingyi's expression in his eyes, and sighed secretly in his heart.

After more than half an hour, everyone calmed down one after another, with the shock brought by this question, the people who asked the next question were really scrambling, fortunately, this is the Jixia Food Palace, and the Holy Overseer, otherwise it is estimated that it can be pinched.

For everyone's questions, Qin Yu answered all the questions, and they all answered in great detail, and even explained the principles clearly, which opened everyone's eyes and accepted the baptism of shock again and again.
