In mid-air, a slightly chubby figure flickered and rushed forward, the posture was not graceful, and there was an ordinary bottle in his right hand at some point. The bottle is filled with a black liquid. I saw that the moment Mr. Cui unscrewed the cap of the bottle, there was a fluctuation of energy in the air. At least Yi Hui felt the feeling of being excluded. Suddenly, the black liquid automatically peeled off from the bottle, floated in the air, and gradually turned into a ball, the size of a fist. Teacher Cui seemed to be controlling the position of the black liquid sphere, and the large black water droplets were motionless. The middle school students were silent, Yi Hui and Shui Er were behind them, and they didn't dare to come out, very worried that the big black water droplets would suddenly burst and then splash out black ink all over their bodies.

It's a pity that I still think too much. For example, the fist-sized water droplets begin to deform and begin to stretch in two sections, and the direction of the stretch is called a straight. The stretching feeling is like the Monkey King's golden hoop stick, which is long when it is said to be long, but unfortunately it becomes thinner and thinner, until the black line stops elongating, and it is roughly estimated to be 10 meters long. In the next scene, the thin black lines are getting thicker and thicker, and the colors are getting lighter and lighter, and gradually a light black curtain gradually becomes clear. As the black curtain slowly unfolded, a square of black patches was formed, and then an incredible phenomenon occurred, the patches became thicker and thicker, and finally formed a complete cube. All these changes, Mr. Cui did not speak, just floated in the air and watched the spatial changes.

To tell the truth, Yi Hui, I didn't know why at first, but later I found out that this is called point movement into a line, line movement into a surface, and surface movement into a body. Looking at Shui'er again, he was contemplative and did not express his position. After waiting for the change to be completed, Mr. Cui threw out several bottles from the bracelet, which were in various colors, including red, green, blue, orange, yellow, purple, and cyan, and then threw the seven bottles to the seven students one by one. The rest of the students were very envious, staring at them with big eyes and dry eyes, and Teacher Cui saw it in his eyes, the corners of his mouth twitched, and he was very proud, and he definitely didn't have a beaten expression. Then the next action, everyone's hearts were happy, this math teacher was teasing the students. One after another, many bottles were made in a tricky way. Even Yi Hui and Shui Er got purple and blue bottles, respectively. The expression of excitement was palpable.

"You wait a while to release the liquid in the bottle. Let me be clear first. After a while, please stay away from each other and don't let the transformation water released by the other party stick to each other. Don't forget! Otherwise, the two geometries will disappear. This is similar to soap bubbles. I'm done, let's spread out with each other! ”

As soon as the words fell, the whole sky saw some students begin to expand their fields outward. In the end, the scattered students fought on their own, ready to release the transformation water. No one knows what shape of geometry the deformed water will become. Some students were in a hurry to release it, but unfortunately this deformed water turned out to be a regular octahedron, and a pyramid-shaped regular quadrangular pyramid was directly formed less than fifty meters behind it. The purple deformed water released by Yi Hui finally formed a perfect purple ball, and the deformed water of the water formed a blue regular pentagonal prism. It is easy to look back at the realm of other people, and then look at the sky, it is really lively, and the geometry of various colors echoes each other in the air. The sky is like a blooming flower, purple and red, blooming in all colors.

In the sky, floating geometries of various colors, flutes and non-flutes, convex polyhedra and concave polyhedra. The whole process took less than 5 minutes, and the entire geometry was released. The students cheered, especially the girls, and they chattered non-stop. The boys formed their own group and laughed non-stop.

Teacher Cui frowned, so he gathered his classmates and temporarily stayed away from the geometry that bloomed in various colors. This geometric gathering is spectacular. But Shui'er held her chin in her hand, looked at Yi Hui a little boredly, and said uninterestedly: "Stupid master, do you think the flying geometry is interesting?" ”

Yi Hui said with a smile: "I think it's still a little interesting, I always feel that there is still something missing, which is not enough to support the teaching task of this class." It seems to be an appreciation lesson. There is no mathematical calculation. There are no theoretical explanations and explanations. ”

"Doesn't geometry count area and volume?" Shui Er proposes a possibility.

And at this time, Mr. Cui's dialect sounded, "The effect of deformation water, let me first say that deformation water itself needs energy, and from the moment it is released, the change has already begun." So, please stay calm. ”

Sure enough, everyone looked back and saw that the various geometries in the sky began to stretch and deform. Some are bulging, some are deflated, but they still don't stop changing.

Yi Hui saw his big purple ball, which began to get smaller, like a deflated ball. Looking at the other geometries has also become smaller, it is only a blink of an eye, and the sky was still occupied by various geometries of various colors before, and now there is no longer the scene of flowers in full bloom. With the deformation of the water after the return to its original state. The mutation began, and the purple deformed water that was easy to return began to have some subtle changes. Re-jog into a line, the movement of this point is concave and convex, and then the line moves into a surface, Yi Hui found a clue, a piece of sheet similar to the shape of a car is formed, and the last step, the surface moves into a body. As the face bends, a purple sedan is finally formed. It's a pity that the purple sedan is like a stereoscopic projection, which only has a sense of technology.

The blue transformation of the water eventually turned into a massive blue airship. The airship is also engraved with red letters. Looking at the sky, a red tree has a large bright red apple, and the size of the apple is almost like a human head. On the other side, a yak is making a bull state, which is mighty, and the students are amazed. "Wow, wow, wow" non-stop. The most exaggerated thing is that there is a brown deformed water and a small brown building with multiple floors, and there are also staircases.

The funniest thing is that someone released the earthy yellow deformed water, which simply turned directly into a large area of platform, on which there were flower pots without flowers, and then no longer changed. The brown multi-story building was dragged to the top of the platform, and it fell down with a bang, and the geometry of the two colors was actually glued, and it did not disappear. Yi Hui's jaw dropped in shock. Isn't it impossible to stick, many students looked at Teacher Cui, and Teacher Cui said "uh" and said, "This is purely accidental!" If the transformation ends, the combination will not disappear! Teacher Cui laughed and said with a smile. The students are "Cut!" "Yes.

"Hey, hey! What kind of attitude do you have? I still won't say, what will change in the end, see for yourself! ”

"Heavenly Palace!"

Several auspicious clouds float over a palace-like building, with a staircase leading to the top of the main hall. At the top of the main hall, there is a colorful streamer at this time, which is beautiful and holy. "Is this a palace made of deformed water?" Shui Er began to move, turned to look at another platform, the modern building was located behind the hill, a fashionable high-end car parked at the door, and a small purple man with clear facial features came out of the car, guarding the door.

This is the rhythm of waiting for the owner to get in the car! "Interesting, interesting!" , Shui'er's eyes lit up, and she finally found something interesting. But after a closer look, the little purple man invited him to get on the car, which was very boring and single. Yi Hui laughed out loud and was glanced at by the water.

Shui Er looked at his airship, hanging in the air, the propeller turned, driving the whole airship forward, not fast, but also slowly flying into the distance.

"Can you stop the airship?" Yi Hui asked Shui'er, but Shui'er didn't pay attention to Yi Hui.

"Shui'er, why don't you look like you anymore, Shui'er, Shui'er has changed to lively mode."

Shui'er's eyes changed and changed, with a sly smile in her eyes.

I saw Shui Er kicking the ground with both legs, jumping on top of the airship, and his little hand grabbed the hatch of the airship tightly, and with a hard slap, the hatch was shaken open.

This series of actions made Mr. Cui's eyelids tremble, jumping and jumping, Mr. Cui seemed to know that this girl was not a student, could it be the inspector's bodyguard, so strong?

The water entered the cabin, and I didn't know how to operate it, and the airship was not far away from everyone.

"Teacher, why is the Transfiguration Water so magical? It's really up and running! In this lesson, I figured out that there is no geometry without change, and there is no mathematics without change. ”

Teacher Cui snorted, to be honest, even he felt that the effect of deformation water was more than that. So he smiled and said: "Geometry is not limited to this, the application of deformation water will be continuously enhanced and upgraded in the future study, I hope that students will be good at faking things." ”

"Today's geometry is over, and the next math session will be held tomorrow."
