"Oops, oh bad, I forgot to talk to you guys!" Gong Yizhen walked over with a look of chagrin and picked up the parts scattered all over the place. Pen, fun, pavilion www. biquge。 info

"Teacher, this... What is this?" Shui Xuanyue's face was a little red, thinking of his voice just now, 'Where is the demon', she was really embarrassed.

"It's a machine car, it's still in the development stage, but unfortunately it doesn't work out. You don't understand, but you'll understand later. Gong Yizhen picked up these things and smiled helplessly.

"Can't control the power?" Ji Yun couldn't help but speak after being surprised.

Yun Gui smiled: "What kind of garlic are you pretending!"

Gong Zhenzhen didn't think much about it, just as a teacher's professionalism, he nodded: "Yes, this steel bar is a source of power, but it can't be controlled." ”

Ji Yun can see clearly, this is a clockwork, rolled into a flat shape, and when it is curled, there will be elastic potential energy, and when the clockwork is bounced open, the elastic potential energy is released, which is the source of power.

In the early days of the previous life, the clocks used the hammer original clockwork, but now there is a clockwork, and it seems that the steel bar is extremely tough, so it can not make a watch?

"Can you show me?" Ji Yun was excited in his heart, looking at these familiar things, his whole person seemed to have returned to his previous life, and a feeling of relaxation and pleasure suddenly arose in his heart.

There are clockwork, there are gears, and the hammer is easier to find, and with the ability of the public to lose the family, it is definitely possible to make a clock!

Gong Yi Zhen smiled: "What, you want to study?"

As he spoke, he put a large pile of parts on the ground, looked at the three of them, and then pointed to the clockwork: "This is the power system, it is made of refined steel bars, and this is the concave cam, which can be buckled with each other and can change the direction of power transmission." ”

Ji Yun didn't listen to his explanation, and fiddled with a lot of materials: "Why don't you fix a bearing that can rotate at one end of this steel bar?"

"Can be rotated...... Can you spin?" Gong Yizhen's eyes suddenly released a fine light, and he suddenly grabbed Ji Yun and laughed: "Good nephew, you are really a genius, why didn't I think of it?"

Ji Yun was suspended in mid-air, his breathing was difficult, his face turned red, and he hurriedly shouted: "Academy... There is no family affection in the school!"

Gong Yi was stunned, and quickly let go, staring at Ji Yun like a beast staring at a little sheep: "Xiao Yunzi, how did you think of it?"

Ji Yun took a big breath, mediated his breathing for a while, and then pointed to the clockwork: "You don't understand what I mean, I understand, you are using the thrust at this end to push this tooth... The concave cam is fixed inside, so of course it is difficult to control the power!"

Ji Yun has dismantled a lot of clocks and watches, and when he was a child, the orphanage also had that kind of winding toy car, and he also dismantled a lot, and he was extremely familiar with the working principle of the clockwork and gear coordination, and he could see the defects of the public shock at a glance.

The clockwork is fixed to a rotating shaft at the central end and the outer end to a pillar that cannot be moved.

The mainspring wants to loosen, and because the peripheral end is fixed, the mainspring can only be loosened by rotating the central shaft, in this process, the elastic potential energy is released, and the central shaft rotates by this, and then the gears and pendulums are used to limit the rotation speed and cycle.

The male shock is just reversed, using the outside end to bounce the gear, not only the energy consumption is huge, but also extremely difficult to control, and it is even impossible to rewind the clockwork.

"That's right!" After all, Gong Yi Zhen is a member of the Gong Loss family, and these things are thorough at all, "Why didn't I think of it?"

"Hey, Xiao Yunzi, are you really blinded?" Yun Gui looked at Ji Yun in surprise, yesterday the two iron balls landed at the same time and they were able to be blinded, and the feather and the iron ball landed at the same time and were also blinded, and today they were blinded again?

Gong Yizhen shook his head: "It's not Meng, this is wisdom! Ji Yun, I'm optimistic about you!"

Gong Yizhen's eyes were full of joy, and he turned his head to look at the copper kettle dripping on the side: "It's almost time!"

Ji Yun also glanced at the drip and shook his head secretly, such a timer should be eliminated.

However, he would not take the liberty of telling Gongzhen his watchmaking philosophy, he would rely on this thing to earn himself a knighthood.

Once knighted, he will have his own fief at that time, and it will be much easier to do anything at that time.

Shui Xuanyue looked at Ji Yun deeply, is this son really extremely wise?

As he spoke, the other students also came to the school, and when he saw Ji Yun, his eyes suddenly narrowed, and he didn't say a warning, but sneered and stood aside.

"Hmm, you still dare to come?" At this time, Lao Qi and several of their princes also arrived.

Immediately, a man with a horse's whiskers shouted next to him: "This scourge is actually coming, kill him!"

"Silence!" Gong Zhen saw all this in his eyes, glanced at Ji Yun, his eyes showed a look of worry, and then waved his hand: "All the students come with me, this is not a classroom!"

Everyone followed Gong Yizhen out of the hall, repented and retreated to the end, discussing something in a low voice with the old seven.

"I can't beat these people now, and even if I can fight them in the future, I can't blatantly kill them, or...... I can kill people accidentally!"

Ji Yun had a killing intent in his heart, and as soon as the killing intent of the clinker was raised, Gong Yizhen, who was walking in front of him, suddenly stopped, looked back at him, and said in a solemn voice: "Don't mess around!"

Ji Yun's heart sank, and the thought that his father had always given him was that his mother's family cultivation was not very strong, and their strength lay in the architecture, organs, and formations.

But at this moment, it seems that this uncle's cultivation is also unfathomable, and he only has a little killing intent, and he keenly perceives it!

They came all the way to the main road between the rows of houses, which was paved with iron and sand, flat and dry, and extremely hard, unlike the dirt road outside, which would be muddy when it rained, and after a few turns, they came to the door of a huge room.

There were already people waiting at the door, and when they saw the students coming, they stretched out their hands and pointed in the air, but they didn't know where they hit, but they heard a loud bang, and a huge window immediately opened around the boxy bungalow, and at the same time a wide stone door also opened.

"Let's go in!" Gong Zhen turned around and smiled, and walked in first.

Ji Yun followed up, and saw that there were rows of tall bookshelves in the center, surrounded by wooden tables with a faint fragrance, Ji Yun recognized them at a glance, these tables are made of Qingshen wood, which can clear the mind and eye-catching, make people energetic, concentrated, and have no sense of irritability when reading.

"This is a collection of all kinds of inventions and theoretical knowledge of the Gewu Zhizhi Academy, you can read it here in the morning, the academy will bring food in the afternoon, and we will have the first class in the afternoon. ”

After Gong Zhen finished speaking, he nodded towards Ji Yun: "Ji Yun, you come with me!"

As soon as his words fell, he heard Ji Shaohong sneer: "Teacher, are you going to give Ji Yun a single meal?"

Gong Yizhen's expression was cold, and his voice was flat: "What does this student mean by this?"

Ji Shaohong saw that Gong Yizhen actually called him a student, and his anger suddenly rose: "As far as I know, the teacher is Ji Yun's own uncle, so if you ask him out alone, is it because you want to leave the relationship?"

"Yes, since everyone treats everyone equally, if there is anything, say it publicly!"

"Yes, openly!"

Ji Yun couldn't cry or laugh, and Gong Yizhen was even more speechless, opening the back door?

"Okay!" He was not angry, and turned his head to look at Ji Yun: "Ji Yun, have you had breakfast? Have you been studying hard lately? Have you worked hard in your cultivation? I caught a bird yesterday morning, it's very beautiful, do you want it?"

"Poof..."Shui Xuanyue couldn't help but be amused, although Ji Yun couldn't help laughing, she also held back her stomachache, her uncle's hand was really amazing!

"Okay, I'm done, you!" Gong Zhenzhen said and walked out.

The room was spacious and bright, and the students went to the shelves to get their books, but strangely, only the books in the first row of the shelves could be moved, and the rest seemed to be closed by some powerful force and could not be held at all.

Gradually, everyone also knew, and they came to the first row of bookshelves, looking for the books they wanted to read.

"The Preliminary Idea of Force", "The Theory of Power Transmission", "On How to Skillfully Use the Principles of Mechanics in Architecture", ......

The books are all in the form of handwritten notes, and when you look at them, they are all high-level theoretical knowledge, and there are no examples of iron balls and feathers landing at the same time that you were interested in yesterday, and so on.

Ji Yun swept over one by one, and found that the books here were all physics knowledge he had learned in his first year of junior high school, and he took out a copy of "The Great Significance of Heavenly Craftsmanship in Agriculture" and prepared to return to the desk.

As soon as his hand pressed on the book, a ruler pressed down on the book.

Ji Yun frowned slightly, turned his head to look, and saw Lao Qi leaning on the bookshelf, with a sneer: "I want to read this book!"

Ji Yun didn't bother to argue with him, walked away a few steps, and casually took one of the books.

As soon as the clinker hand was put on the book, Ji Shaohong's ruler came up again.

"What are you going to do?" Ji Yun stared at Ji Shaohong coldly.

"What's the matter, just reading a book!" Ji Shaohongpi didn't smile, but looked like a hooligan, not a noble prince.

Ji Yun suppressed his anger and pointed to the bookshelf: "Then you go first!"

After saying that, he actually left directly, walked to the edge of the desk and sat down, his eyes turned outward, and he looked at the scenery.

Who knew that Ji Shaohong didn't give up, grabbed a book casually, actually followed, took out a ruler and patted Ji Yun on the shoulder: "Hey, let me go, I like this position!"

Ji Yun couldn't hold back any longer, and stood up.

"Ouch..."

As soon as he stood up, he watched Ji Shaohong wail, and then fell down softly.

"Touching porcelain?" Ji Yun was dumbfounded, how could it be like this?

He didn't think about it, so he shouted loudly: "Teacher, come quickly, Ji Shaohong has a seizure!

The dignified son went crazy, and this was worth it, and a few teachers outside the door rushed in a few steps.

Ji Shaohong lay on the ground and scolded in a trembling voice: "Fart, it was Ji Yun who beat me!" Ji Yun ......"

"Ji Yun, you are so bold, you actually dare to openly fight in the academy and be expelled!" Yesterday, the goatee Qu Shansi appeared again.

"Damn!" Ji Yun scolded in his heart, the emperor really follows his words, every word and deed can determine the fate of a person's life, he only slightly shows his distrust of King Ling, and the courtiers dare to attack him like this.

"Ahh

Ji Yun suddenly glanced at his eyes, boomed, and also lay on the ground.
