Chapter 172 Sha Xiaojing's Invention

"Boss, second. When we get down to the top of the mountain, I will show you a treasure I invented, which will definitely open your eyes." When getting off the car, Sha Xiaojing said suddenly.

"Is it just in your bag?" Xiao Fei asked. When the three of them left school, Sha Xiaojing went home to pick up a big travel bag and put it in Zhu Xiaojie's car. When I got in the car, I asked him and he didn't say anything. Only then did he take it out to offer the treasure.

"Yes!" Sha Xiaojing said, "I can guarantee that this is definitely the greatest invention since this century."

"The greatest invention?" Both Xiao Fei and Zhu Xiaojie became interested, "Then why don't you show it to us?"

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

"That's fine, then you can slowly carry the package up the mountain by yourself, we are too lazy to carry it for you." Xiao Fei said.

After speaking, the three of them walked up the mountain together. Goal, Lotus Temple.

Not long after, I came to the top of a hill below the Lotus Temple. Connecting the wide road below the mountain, there is a pavilion on the top of the mountain. Because it is the top of the mountain, the terrain is very steep, and the slope of the road is also very steep.

Xiao Fei and Zhu Xiaojie didn't take anything, so it was relatively easy to get here. But Sha Xiaojing was different, he carried the travel bag on his back all the way, sweating profusely from exhaustion. It can be seen that the things in his bag are relatively heavy.

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

"It's fine here, the terrain is very suitable." Sha Xiaojing said as she put her travel bag on the railing of the gazebo.

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

"Dangdangdang...dang!" Sha Xiaojing called out rhythmically, then opened the travel bag. Xiao Fei and Zhu Xiaojie took a look and saw that there were some wood, iron parts and other things inside, "Is this what you said, the greatest invention of this century?"

"You guys don't understand." Sha Xiaojing said proudly, "I spent a vacation making this, and the name is 'Create the world, super invincible rocket car!'. Now you may not know how powerful it is. ...and when I'm done, 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 the whole thing looked like a small car, 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, there are also four stainless steel cylinders tied.

"This is your super invincible rocket car?" Xiao Fei and Zhu Xiaojie were surprised, "Then how do you use it?"

"Have you learned it?" Sha Xiaojing said proudly, "I filled the four cylinders with strong gunpowder. People sat on them and then slid down the hillside, and at the same time I lit the four fuses. The gravitational potential energy of the rocket car's slide, plus the back thrust of the 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 theoretically successful at present." Sha Xiaojing said: "But I have no chance to try it myself, because no one pushes me from behind."

Xiao Fei looked at the foot of the tens of feet high mountain, and smiled evilly, "Why don't you try sitting on it first?"

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

"Then sit on it! We'll help you from behind." Fat Paper also said with a sinister smile on his face, encouraging him.

"Okay!" Sha Xiaojing said, "Second brother, push the cart at the back, and boss, help me light the fire!" After speaking, this guy really sat on his rocket cart.

"What are you waiting for, let's start!" Sha Xiaojing said.

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

"If his calculation of the amount of gunpowder is accurate enough, he may land safely." Zhu Xiaojie bowed his head and thought for a while, then said, "The potential energy of gravity is downward, and the force of the rocket launcher is upward obliquely. The resultant force of the two forces is parallel to the ground. ..."

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

So the two of them really fulfilled Sha Xiaojing, first pushing the rocket car to the top of the road. Then Xiao Fei took out the lighter from Sha Xiaojing's pocket, and started lighting the lead wire at the bottom of the cylinder. He ignites very quickly, trying to do it all at the same time.

Chi Chi Chi!

The lead wire started to smoke, and seeing this, Zhu Xiaojie pushed the car down hard. The rocket car Sha Xiaojing was riding on slid down at an extremely fast speed, and there was still acceleration.

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

boom!

Suddenly, one of the four cylinders burst into flames, and tongues of flame gushed out of the cylinder. Then... the huge force caused the rocket car to change its direction, and rushed out of the road at a high speed, and beside the road, there was a high cliff!

And Sha Xiaojing was on the rocket car, her face turned pale with fright.

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

In a very short period of time, the rocket car Sha Xiaojing was riding on bounced in the sky and changed directions. He actually made a turn in mid-air on the top of the mountain, then rushed back to the road and hit the stone wall directly.

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

This nima is too scary! Xiao Fei's heart thumped wildly. When he saw Sha Xiaojing was about to fall off the cliff, he just wanted to help, but he didn't expect the second cylinder to let him fly into it again. Just as he let go of his hanging heart, the third bazooka pushed him out again... Xiao Fei, who was harmed, gathered two exercises and wanted to enter the immortal mode twice.

"Big Ban Ya, how are you?" Xiao Fei and Zhu Xiaojie rushed down.

"Damn, this is so exciting!" Sha Xiaojing said excitedly, "You can't imagine that feeling unless you experience it yourself! It's like riding a roller coaster in the sky!"

Stretching out his hand to touch his head, there was blood on his hand. He was slightly injured when he hit the stone wall just now.

"You bastard, if you were unlucky just now, you would have fallen 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, regretting that he shouldn't be pushed down. And Xiao Fei has the ability to save him, so he doesn't care much.

"It doesn't matter, inventions and creations will always encounter some danger!" Sha Xiaojing said, "And it turns out that my theory...is very successful!"
