Gaojia Village.

Early in the morning, the hard-working villagers of Gaojia Village had already gotten up.

The farmers went to the fields, the workers went into the factories, and even the old village chief sat at the door of his house, weaving a pile of bamboo strips into small birds and grasshoppers, ready to sell them at the market for a copper coin to amuse the children.

Such a morning is no different from every morning of harmony.

However, at the gate of the 32nd Middle School in Gaojia Village, a picture that was not so harmonious appeared at this time.

Song Yingxing, Wang Zheng, and a large group of graduate students, senior technical engineers, and blacksmiths were watching a huge iron car.

The car made by Bai Gongzi!

The main part of it is almost entirely made of steel, except for four tires covered with black rubber given by the Celestial Venerable. At the front of the car is a distinctly boiler-shaped thing with a long chimney sticking out of it.

Bai Gongzi's face was excited: "The car, the No. 2 machine, officially started the test run today." ”

He shouted this impassionedly and confidently, but the crowd of onlookers behaved very flatly.

After all, Bai Gongzi's car No. 1 was a joke for everyone.

When the No. 1 machine was made, the power of the steam engine was still very weak, and it could not carry a heavy body, so the body was made of wood. Bai Gongzi forgot to put brakes on it again, and he couldn't brake when he drove it, and he turned into the field twice, and the wooden body was not strong, and it fell apart in an instant.

Later, Bai Gongzi tested many times, but all ended in failure.

As a result, everyone in Gaojia Village has put a huge question mark on the feasibility of the "car".

Bai Gongzi's No. 2 machine was launched this time, but of course it did not get everyone's enthusiastic response.

"Xiaobai, have you put on the brakes this time?" Song Yingxing couldn't help but ask.

Bai Gongzi: "Hahaha, eat a trench and grow wise, this time the first thing I designed was the brake." ”

Everyone: "Don't put the brakes first, what about power?" This time, I used an all-iron body, and the car was very heavy, right? Can the steam engine be moved? ”

Bai Gongzi snorted and laughed: "I dare to use the all-iron body, because the steam engine has been improved, and the power has been greatly improved. ”

Everyone: "Yo yo yo! ”

Bai Gongzi: "Just wait and see, hum!" Ignition! ”

A graduate student who had been doing research with Bai Gongzi for a long time jumped out from behind, took out a fire fold, and threw it into the boiler.

Boiler ignition, soon! The coal that was placed in it then burned.

The steam engine began to spew white gas.

Bai Gongzi's face was proud: "See?" The steam engine is already running, but my car is not moving forward now, because I have the brakes, hahaha, I'm stepping on the brakes now. ”

Everyone: "Don't be complacent about this little function! This is the basic function that the car must have, what kind of car is it if the brakes are not done well? ”

"Okay, now I'm going to show you how powerful this car number two is." Bai Gongzi's right foot was raised and the brake was slightly released.

At this moment, the pent-up power was finally released, and the car slowly ...... Drove forward.

Everyone: "Wow, it can really move." ”

"It's so heavy that it moves."

Song Yingxing and Wang Zheng glanced at each other, and their eyes were full of excitement: "Xiaobai's improved steam engine is so powerful, although it is not large, it can pull such a heavy all-iron car." ”

"This time, the transportation capacity of my Gaojia Village is about to enter a new chapter."

Bai Gongzi held the steering wheel with his left hand, and lifted the lid of a box next to the chair with his right hand, and the box was full of briquettes, one by one made very cute and beautiful.

Bai Gongzi grabbed a briquette, threw it into the boiler, turned the steering wheel with his left hand, turned his body at the three-way intersection at the school gate, and then drove north.

The infrastructure of Gaojia Village is the best, the cement road has long been built in all directions, and there are even street signs at every intersection.

The car drove to a huge intersection, the sign on the intersection was painted, turn left to Chengcheng County in the west, turn right to Heyang County in the east, and go straight to Huanglong Mountain in the north.

Bai Gongzi laughed and drove on the road to Huanglong Mountain.

A large group of graduate students chased behind, wanting to follow to see the excitement, but they didn't expect Bai Gongzi's car to drive faster and faster, and soon exceeded the speed of 30 kilometers per hour, and the onlookers couldn't catch up by throwing ham.

Wang Zheng was in a hurry: "Hurry, bus sun car, get a bus sun car, we can follow." ”

Everyone suddenly realized, and hurriedly rushed to the gate of the main fort, where there is a "Gaojiacun Bus Hub Station", and there are many idle and useless buses.

The school boss wants to call the bus, how dare the station administrator say a word, and quickly approve a special one back to the main station to overhaul, just repaired and is planning to re-put into use the 86 bus sun car for everyone to use.

The driver was the same driver who transported the messenger Li Yuan in Huanglong Mountain, and the car was also the same car, and the car skills were the same, and he yelled: "Everyone, sit tight." ”

The BGM of the shrimp catcher sounded, and the driver shook the steering wheel and rushed in the direction of Huanglongshan, and the car was full of scientists and graduate students, all of whom looked forward with wide eyes.

Eighty-six deserves to be eighty-six, and soon caught up with Bai Gongzi in front.

I saw that the No. 2 machine of the car was driving smoothly on the road, and from time to time it made a "woo" sound, spewing out a large amount of smoke.

From time to time, Bai Gongzi grabbed a briquette and threw it into the boiler.

However, sitting so close to the boiler will inevitably be a little hot and sweaty. After Bai Gongzi grabbed the briquettes, he wiped his sweat on his face, and as a result, a face as warm as jade was made into a big flower face by himself, more like a migrant worker than a migrant worker.

Bus No. 86 equaled the car, slowed down, and the two cars were parallel, and Song Yingxing poked his head out of the window: "Hey! Xiaobai, where are you going to drive all the way like this? ”

Bai Gongzi smiled: "Of course, it's back to Baijiabao." ”

Song Yingxing was secretly shocked in his heart: "Forty miles? How far did you get this car? ”

Bai Gongzi: "I have calculated the weight and mileage of coal, let alone forty miles, even if it is forty miles back and forth, there is no problem." What's more, I can also replenish coal in Baijiabao, and in the future, every city will set up a coal replenishment station, and this car can drive anywhere. ”

Song Yingxing was convinced: "Your invention is too powerful." ”

Wang Zheng: "Tianzun will be very happy when he sees this invention." ”

Bai Gongzi laughed "haha": "In the future, where our cement road is assisted, this car will be able to go, and the transportation of materials will no longer be a problem." ”

Song Yingxing: "The problem is the cost of this car, right?" ”

Bai Gongzi: "......"
