Chapter 878 Zhang Fei: A Science Geek Delayed by the War
Looking at the excited Zhang Fei, Wang Xuan was really speechless. He didn't bother to pay attention to this guy who didn't stop. He just silently watched the test results of this horse-drawn iron cart.

The test site is large enough. It takes 20 kilometers to run a lap, and there is enough time to accelerate the vehicle. Gradually, the horses run faster and faster. Judging by the speed, they have already reached a speed of about [-] miles.

This speed is already very fast, but it is obvious that it has not reached the limit speed, but the face of the driver in front has already turned pale. After all, this is the first actual test. The four carriages are loaded with counterweight iron blocks to test the load. Afterwards, the performance under various road conditions, but, if the car overturned at this speed... the driver felt that he might be crushed into a meatloaf and die without a whole body.

The front is fine, it’s all straight-line acceleration, and the test is speed. In the back, there are curves with different angles, climbing, and downhill. It’s to test the ultimate performance. Seeing the first curve, the driver’s side He waved his whip tremblingly to direct the direction of the horses, while gritting his teeth, for fear of overturning the car.

When cornering, the entire track must have a certain inclination angle. Use the resultant force of gravity and support force, which can also be said to be the component force of the support force in the horizontal direction, to ensure that the vehicle turns smoothly. If it is completely horizontal, then It is necessary to rely on the deformation of the rails to provide centripetal force, which is too dangerous and is tantamount to derailment, so it must be slightly inclined.

Huh~~ The driver successfully passed the first small curve. The driver did not feel the vehicle tilted. Fast deceleration. Fortunately, after the speed decreased to a certain limit, the vehicle finally climbed up. The driver just breathed a sigh of relief when he suddenly felt that the speed of the vehicle suddenly accelerated, and the speed of acceleration exceeded the normal limit.

"Ah!!" The coachman screamed, and subconsciously began to pull the handbrake. The car stopped suddenly, and even the horses pulling the cart neighed for a while. Only then did the coachman realize that he was a little too aggressive, and quickly released the handbrake, and the car stopped. Speed ​​up again.

Slowly, the speed of the car obviously exceeded the time when it was accelerating in a straight line. Fortunately, it did not reach the limit of the horse and was still within the acceptable range.

After safely entering a section of the straight road, the driver breathed a sigh of relief, but he thought that whether it was a curve or a ramp behind, it was more dangerous than the one just now, and he felt like he was going to die.

Cornering, climbing, descending... I passed it safely twice again, but when it came to the third time, something went wrong after all, the corner turned a little too fast.

what! ! !
Amidst the driver's screams, the vehicle derailed directly, and the huge momentum caused the carriage to rush out sideways. Even the four horses in front were not spared, and were directly taken out by the carriage amidst the neighing.

Seeing that the coachman was about to be crushed to death on the spot, he suddenly felt his body lighten and tighten again, and the whole person flew out directly, making a long scream, and flew more than ten meters before landing safely. Slowed down, he let out a long sigh of relief when he found that not only was he not dead, but there were only some scratches on his body, but his whole body was completely soaked in sweat, um, his pants were a little too wet, and some unknown liquid began to flow down tick up.

"Damn it!" Zhang Fei kicked the coachman out with a sound of scolding, "He actually pissed, what a coward!"

"Okay, you are as thick-skinned as others!" Wang Xuan glared at Zhang Fei and said, "Take the coachman down, so you can get a reward."

"The test results are obvious. Let's take the last curve and slope as the maximum standard. There is no need to test the limit. Judging from the results of the current test, the original design plan has been achieved."

A group of people walked back while saying this. On the way, Wang Xuan said to Liu Bei: "In the previous war, the grain and grass needed by an army of [-] people needed [-] civilians to transport it. As the duration of the war increased, the grain and grass transportation With the increase in distance, less than one-tenth of the food and grass used for the soldiers is actually consumed, and the other [-]% is wasted out of thin air, and a large number of civilian laborers are recruited, which delays the planting of food and causes even greater losses."

"And the civilian husbands have no money or food, leaving their wives and children helpless, causing local turmoil and other problems. Under a series of chain reactions, the cost of war is extremely high. In many cases, it takes several years or even ten years to accumulate enough to launch a war. This is also the reason why the national power will be exhausted even when the war is victorious and a large amount of spoils and land are obtained. The most obvious example is the passage of the early Han Dynasty. After Jing Zhizhi', the national power was strong, and after Han Wudi destroyed the Xiongnu, he harvested countless cattle, sheep and horses, but the national power declined sharply."

"With the railway, it's different. The transportation cost is so low. If the chain reaction is counted, it can be reduced to one percent of the original level. There is almost no loss of national strength. As long as the railway construction keeps up, wars will be waged year after year. It will only get richer and richer."

"The importance of the railway is no different from the lifeline of the country to a country. Wherever the railway goes, the rule can be extremely stable. The influence it brings is not just a matter of how much money is made. This is what I have made up my mind to The reason for the construction of the railway is like the area around the capital where the ruling power of the dynasty is the strongest, the reason is that the distance is close enough, and the railway can expand this distance by dozens of times."

Liu Bei half understood what he heard, but he remembered one thing, the railway is the lifeblood, with the railway, the dynasty will not decline!
When the group arrived at the house, Zhang Fei, who was dizzy from listening all the way, suddenly regained his energy. He patted Wang Xuan's arm, pointed to something in the distance and said, "Zaizhi, what is that thing?"

Looking in the direction of Zhang Fei's finger, it was a four-wheeled flat car parked on the rails, with a seesaw-like lever on it.

This thing is called a 'human rail car', and it was originally designed as a vehicle for inspection along the railway line. It is powered by two people pressing the seesaw back and forth, and it travels very fast.

"This, the human-powered rail car, is a vehicle that can drive automatically without the need for horses, as long as you step on the seesaw in the middle back and forth."

Wang Xuan explained something casually, but Zhang Fei jumped on it with great interest as soon as he finished speaking. It was supposed to be a human-powered rail car that two people stepped on each other, but he split his thighs and stepped on it alone.

The power transmission device of this thing is extremely simple, but the simpler it is, the smaller the intermediate loss and the faster the relative speed. Before Wang Xuan could say anything, Zhang Fei, the giant monster, stepped on the human-powered rail car and 'shot' it out. .

Yes, it can only be described as shooting, the speed is too fast, just like the acceleration of a motorcycle with a large displacement from [-] kilometers far exceeds that of a car.

With just one breath, in about three or four seconds, the human-powered rail car was stepped on by Zhang Fei and flew past the crowd at a speed of about 40 mph, leaving only a burst of magical laughter echoing in the air. .

When a few people chased out of the house, the speed of the rail car definitely exceeded 60 mph. Zhang Fei screamed excitedly, his legs exerted strength again, and he almost stepped on the phantom, and the speed of the rail car suddenly jumped up a step He rushed up the first ramp like flying, and then... whoosh... ah... bang...

The rail car was shot directly from the ramp at high speed, and finally jumped more than ten meters away before falling heavily to the ground.

That is to say, Zhang Fei is the one who controls the vehicle. If an ordinary person flies out at this speed, he will have a powder fracture when he finds it. However, this guy didn’t come down after flying out. He turned his head and flew back directly. After landing, he rushed excitedly. Wang Xuan shouted: "How about it, Zaizhi, this is much faster than your horse-drawn cart!"

"Hurry up, sir!" Wang Xuan rolled his eyes fiercely, "You are as strong as anyone, stronger than an animal, and you can fly the railcar away!"

"Uh, there must be very few people who are as strong as me, but..." Zhang Fei rolled his eyes and said with a smile: "Can you find more people to step on at the same time? I think it is better than a horse. Things are animals after all, so they may not be so obedient."

Wang Xuan was stunned and blinked his eyes. After all, this world is different from the normal one. People's strength is several times stronger than normal, so it may not be impossible!

Especially under the premise of pursuing faster speed, after all, horses are tied to ten horses, and more can't be controlled, but it doesn't matter if people talk more!

Wang Xuan looked Zhang Fei up and down, and said, who is this guy pretending to be? Why did he suddenly become smart? Or, this guy is a scientist who was delayed by the war!
