"Oh, it's only been a day, you've got it figured out, what is it?" Gong Yizhen's eyes lit up, he had long been sure that his nephew was not Mai Mang, who fell into the eye of the needle and happened to say those strange theories, but really had an amazing talent.

"It's... I'm tentatively named a clock, it's a more accurate timer!" Ji Yun explained, "I think our previous timers are nothing more than copper kettle dripping, sundials, and even most people look directly at the sky, and there is a little incense, a cup of tea, etc., that is not accurate!"

Everyone's eyes widened, could there be a more accurate timekeeper than a copper kettle dripping and a sundial?

"Explain it quickly, we can also help you improve it!" Gong Yi Zhen glanced at Gong Yi Ghost Axe, and hurriedly urged Ji Yun.

Ji Yun nodded, picked up a piece of white paper, drew a large circle with a brush, and then looked up at Gong Yizhen: "Our time says like this, when we are young, when we are ugly, when we are ugly, when we are young, when we are ......."

As he spoke, he drew twelve scales on the circle.

"Well, that's right, that's the case with sundials, but if it's cloudy and rainy, sundials are useless. Gong Yizhen nodded, with a contemplative expression, but he still couldn't guess Ji Yun's thoughts.

"What do you think this looks like?" Ji Yun suddenly picked up the paper and showed it to Gong Zhen through the sunlight outside, "Doesn't it look like your concave cam?"

Gong Yizhen looked confused.

Ji Yun sighed secretly, it seems that guided teaching is not good, and he can only say it in one go.

So they talked endlessly, how to use the clockwork to drive the gears, how to use the cycle of the pendulum to control the rotation of the gears, and how to use the large and small gears to drive different speeds......

The more others listened, the more confused they became, but as some teachers of the Gewu Zhizhi Academy, the more they listened, the brighter their eyes became, especially the two members of the Gongyi family, who almost interrupted Ji Yun's words when they listened, and said it back and forth.

They've got it.

Twelve hours, twelve scales, and various knowledge inherited by the Gong family, combined slightly, immediately understand the working principle of this clock.

"Perfect! God-given artifact!" Qu Shansi has a deep study of mechanics, and when he heard Ji Yun say about the movement of the pendulum and the change of gears in mechanical transmission, by the time Ji Yun finished speaking, he was completely lost in the wonderful picture of the rotation of gears and the balance wheel and clockwork in his mind.

"Inform all the vigorous heavenly craftsmen and skilled craftsmen in the Gewu Academy, make it immediately, and strive to make it today!"

Ji Yun was taken aback, one day, it was so powerful, but after thinking about it, he understood that the public lost the ghost axe probably thought that this thing was the kind that was going to be made big, and that kind of natural simplicity.

He thought for a moment and looked at Gong Yizhen: "We can not only make it big, but we can also make small ones! Uncle, think about it, if it is made the size of a coin, and anyone has a piece and hides it in his arms, wouldn't that benefit all the people? Time is unified, and the rhythm of the whole country is brighter and more unified!"

"That's good!" "Gong Yi looked at Ji Yun, his eyes were shining, "Just imagine, every time you go to the court, the emperor has to punish late officials, just because the time cannot be unified, and in the army, if there is a situation where the enemy is flanked on both sides, you only need to agree on the time and launch an attack at a few minutes, so that you will be more disciplined and more able to enhance combat efficiency!"

What these people thought of was far more far-reaching than what Ji Yun thought, and this sentence alone made everyone's eyes brighten.

"Haha, the people no longer have to listen to the time in the middle of the night, when they wake up, take out this clock and look at it, the time is naturally clear and clear!" An old man with a farmer's appearance and trouser legs pulled up his beard and laughed, "And this is also of great help to me in studying crop growth!"

"It seems that this person is studying farming!" Ji Yun secretly wrote.

"The deputy hospital, I have been notified to rush down!" At this moment, a teacher came back to report.

"Okay, Ji Yun, you come with me, no, everyone goes, all of us in the Gewu Zhizhi Academy want to witness the arrival of this epoch-making treasure!"

Everyone was about to leave, when they heard someone behind them groaning: "It's over, my title..."

Everyone turned around, but saw that Ji Shaohong's face was like ashes, and he was depressed, only a pair of eyes stared at Ji Yun, as if Ji Yun had taken away his title.

"You have researched an invention yourself, isn't the title still there?" Ji Yun didn't want to speak, but suddenly his heart moved, and an idea came to him.

"Huh? Yes, yes, I have an invention of my own, wouldn't I have been stripped of my title?" Ji Shaohong suddenly felt like a new life, laughed, and his spirit recovered.

Ji Yun was disdainful in his heart, and walked out with everyone.

All the way to the Tianding workshop, this workshop is obviously much larger than the others, it is simply a huge industrial plant, there is no sound outside, but as soon as you enter, you can hear a deafening sound.

Ji Yun really wanted to see how they made gears and other things, he was still guessing if there were molds or the like, but when he saw it in person, he couldn't help but be surprised.

There are no molds, no imaginary lathes, just dozens of people in armor at work.

The way they work is very simple, take a piece of refined iron ore in their hands, pinch it with both hands, and then pull it, and it immediately becomes an iron bar, and then grab this iron bar, just like Lanzhou ramen, and beat it on a huge workbench made of unknown material.

After pulling it up, rub it with your hands again, and it becomes a lump again, and then pull it and knead it again......

Ji Yun was dumbfounded, and his brain was dizzy, it was fine iron, not dough, they actually concocted iron like kneading dough.

"This is the great heavenly craftsmanship and great craftsmanship of the Gewu Zhizhi Academy, using the aura to temper refined iron, the effect is countless times stronger than the flame calcination, these people are actually puppets, so they are so powerful, as long as you tell them about your ideas in the way of divine soul transmission, they will create exactly the same artifact as you imagined!"

Gong Yizhen saw Ji Yun's face full of shock, and he didn't want to say it, for fear of poking at the sore spot of Ji Yun's inferior qualifications, but after thinking about it, he still explained.

"What about the delicate objects?" Ji Yun still felt a little incredible, such as the clockwork in a very small watch, that is, the hairspring, these puppets in armor, their hands are so big, how to get them?

"Hehe, I know you don't believe it, you come here!" Gong Zhen pulled Ji Yun to the side, lifted a straw mat, and suddenly the golden light flashed, revealing a huge plate.
