"Boss, second. When you get to the top of the mountain, I'll show you a treasure I invented, which is guaranteed to be an eye-opener for you. When he got out of the car, Sha Xiaojing said suddenly.

"Is that what you're in this bag?" Xiao Fei asked. When the three of them left the school, Sha Xiaojing deliberately went to the house to pick up a large travel bag and put it in Zhu Xiaojie's car. When he got into the car, he asked him if he still said, and then he took it out to offer the treasure.

"yes!" Sha Xiaojing said, "I can guarantee that this is definitely the greatest invention of this century." ”

"The greatest invention?" Xiao Fei and Zhu Xiaojie were both interested, "Then you can take it out and show it to us." ”

"I'll take it out when it's at the top of the mountain, this place is not suitable for demonstration." Sha Xiaojing said.

"That's okay, then you can slowly carry the package up the mountain by yourself, we don't bother to help you carry it." Xiao Fei said.

After saying that, the three of them walked towards the mountain together. Target, Lotus Temple.

It didn't take long to come to the top of a small hill below the Lotus Temple. It is connected to the wide road below the mountain, and there is a pavilion on the top of the mountain. Since it is the top of the mountain, the terrain is very steep, and the slope of the road is very large.

Xiao Fei and Zhu Xiaojie didn't take anything, and it was relatively easy to walk here. Sha Xiaojing was different, carrying the travel bag all the way, tired and sweating. It can be seen that the contents of his bag are still relatively heavy.

And Sha Xiaojing was also very honest, and he didn't call Xiao Fei and Fat Paper for help halfway.

"It's just here, the terrain is very suitable." Sha Xiaojing put his travel bag on the railing of the gazebo and said.

"Hurry up and show us!" Zhu Xiaojie said.

"Dangdangdang...... While! Sha Xiaojing called rhythmically, but opened the travel bag. Xiao Fei and Zhu Xiaojie looked at it, and saw that it was all wood, iron parts and other things, "This is what you said, the greatest invention of this century?" ”

"You don't understand that, do you?" Sha Xiaojing said proudly, "This is what I made for a vacation, and it's called 'Open the World, Super Invincible Rocket Car!'" ’。 Now you may not know how powerful it is. When I'm ready, you'll say I'm a great inventor. ”

After speaking, Sha Xiaojing began to assemble the parts inside. Within a few minutes, the rocket car was assembled with ease.

Xiao Fei took a look and saw that this thing looked like a small car as a whole, but there was only one seat in the middle. There are four wooden legs underneath, and four wheels are installed under the wooden legs. On the wooden legs, four stainless steel cylinders are also tied.

"This is your Super Invincible Rocket Car?" Xiao Fei and Zhu Xiaojie were surprised, "Then how do you use it?" ”

"Have you seen it?" Sha Xiaojing said proudly, "These four cylinders are filled with high gunpowder. The man sat on it and slid down the hill while I lit the four leads. The gravitational potential energy of the rocket car's slide, combined with the rear thrust of gunpowder, can make it fly! ”

"What an awesome invention!" Xiao Fei and Zhu Xiaojie were amazed, "However, have you tried it before?" ”

"This invention is currently theoretically successful." Sha Xiaojing said: "But I didn't have a chance to test it myself, because no one pushed me from behind. ”

Xiao Fei's eyes looked at the foot of the mountain dozens of zhang high, and smiled evilly, "Why don't you sit on it and try it first?" ”

"That's okay!" Sha Xiaojing said, "This is my own invention, and I should always take risks for the invention." ”

"Then sit down! We'll help you later. Fat Paper also showed a sinister smile on his face, and said encroachmently.

"Good!" Sha Xiaojing said, "Second brother, you push the cart in the back, boss, you help me light the fire!" After that, this guy really sat on his rocket car.

"What are you doing in a daze, let's start!" Sha Xiaojing said.

"If he goes on like this, he won't fall to his death, right?" Xiao Fei said.

"If he had calculated the amount of gunpowder accurately enough, he might have landed safely." Zhu Xiaojie lowered his head and thought for a while, and said, "The gravitational potential energy is downward, the power of the bazooka is diagonally upward, and the combined force of the two forces is parallel to the ground......"

"It doesn't matter if it fails." Sha Xiaojing said, "In this world, there are always some pioneers who will sacrifice their lives for new inventions, and you are my witness." In the future, I will go down in history and appear in physics books. ”

So the two of them really fulfilled Sha Xiaojing and pushed the rocket cart to the top of the road first. Then Xiao Fei took out the lighter from Sha Xiaojing's pocket and began to point the lead at the bottom of the cylinder. He lit the fire very quickly, trying to do it at the same time.

Snort!

The lead began to smoke, and Zhu Xiaojie saw this and pushed the car down hard. The rocket car that Sha Xiaojing was riding in slid down at an extremely fast speed, and there was also acceleration.

It's about to fly! Sha Xiaojing, who was sitting on the rocket car, felt the wind whistling in his ears, and his heart was excited.

Rumble!

Suddenly, one of the four cylinders began to burst into flames, and tongues of fire erupted from the cylinder. And then...... The huge force made the rocket car change direction, and it actually rushed out of the road, and on the side of the road, there was a high cliff!

And Sha Xiaojing was on the rocket car, his face turned white with fright.

Seeing that Sha Xiaojing was about to fall off the cliff with the car, another cylinder suddenly caught fire, and another force pushed the rocket car inside. Then the third cylinder was ignited, and the rocket car was pushed down the cliff, followed by a fourth......

In a very short period of time, the rocket car that Sha Xiaojing was riding was constantly bouncing in the sky and changing direction. He actually made a spin in mid-air at the top of the mountain, and then rushed back to the road and crashed directly into the stone wall.

Then Sha Xiaojing was also thrown out, and the rocket car was also knocked apart.

This Nima is also too scary! Xiao Fei's heart fluttered. When he saw Sha Xiaojing about to fall off the cliff, he just wanted to help, but he didn't expect the second cylinder to let him fly inside. As soon as the hanging heart was put down, the third bazooka pushed him out again...... Xiao Fei, who was harmful, condensed the exercises twice, and wanted to enter the immortal mode twice.

"Big Panya, how are you?" Xiao Fei and Zhu Xiaojie hurriedly rushed down.

"This Nima, this is so exciting!" But Sha Xiaojing said excitedly, "That kind of feeling, if you don't experience it yourself, you can't imagine it!" In the sky, it's like a roller coaster! ”

Reaching out and touching his head, there was blood on his hand. He hit the stone wall just now, and he was slightly injured.

"You guy, if you were unlucky just now, you'd fall off the cliff!" Zhu Xiaojie said.

In fact, when he saw that Sha Xiaojing's life was in danger, he still regretted it very much in his heart, and regretted that he shouldn't have pushed him down. And Xiao Fei had the ability to save him, so he didn't care much.

"It's okay, invention and creation will always encounter some danger!" Sha Xiaojing said, "And it turns out that my theory ...... It was a success! ”
