Daming: Old Zhu, we agreed not to rush!

Chapter 415 Science and Superstition

"Sir, what are you doing?"

Zhu Di looked at Su Jing with a strange look on his face, wondering what Su Jing was doing.

He couldn't see the use of this device made by Su Jing at all.

Su Jing smiled and said: "King Yan, bring the big basin and fill it with water."

Zhu Di didn't know what Su Jing was going to do, but he did it very smoothly.

A large basin for washing clothes was first dragged into the yard, and then Zhu Di filled it up with water one by one.

Seeing that there was enough water, Su Jing immediately put the device in her hand on the water. Of course, she still poured some water into the special-shaped bottle first.

Then Su Jing lit the candle at the bottom of the bottle, and the water in the glass bottle quickly began to boil under the heat of the candle.

Then, the entire wooden board moved in the tub, like a small boat.

"Move, move!"

Zhu Di looked at the device in the basin in surprise. He was shocked and shocked.

Su Jing said with satisfaction: "King Yan, this is a simple engine. When the power of the steam is strong enough, it can push huge objects forward."

"Although the engine on the train is much more complicated than the one I made, the basic principles are the same."

Storytelling can never be as shocking as actual small experiments.

Zhu Di immediately said: "Sir, if this device can be put on the ship, will it be possible to move forward without sails?"

Zhu Di's thinking was still broad, and he directly thought of its use on ships.

Su Jing nodded and said: "Of course it is possible, but simply transferring it up will not work. We have to consider another issue, which is the efficiency of fuel use."

"To put it bluntly, if this engine is burning coal and it is not as fast and durable as manually rowing, then there is no point in using this engine."

In the large basin, as the water in the glass bottle was boiled dry, the entire device completely lost power and stopped.

Zhu Di was thinking seriously about Su Jing's words and looked at the stopped device with a look of confusion on his face.

"Sir, the students probably understand how to use this ship, but the train does not run on the rails, but it has wheels. How does it drive the wheels forward?"

Zhu Di still couldn't figure it out. Su Jing's teaching aids were placed on the water and all he could think of was its application on ships.

Su Jing was not surprised. If Zhu Di could draw inferences and easily understand, Su Jing would be surprised.

"Prince Yan, wait a moment, let me process it again."

Su Jing smiled faintly, turned around, came to a pile of wood, and started tinkering.

Zhu Di became the underling again, handing him one thing at a time and another at another time.

"Young Master Su."

Before Su Jing had finished tinkering, Liu Banxian's figure had already appeared outside the hospital.

He was still dressed the same as before, wearing a faded Taoist robe, holding a semi-immortal flag, and with his gray hair and beard, he looked somewhat immortal.

Of course, the main reason is that I didn't pull any wood today, I feel relaxed and my demeanor is naturally much calmer.

"Liu Banxian, why are you here? The fortune-telling business looks good today. How many customers are there?"

Su Jing looked up and asked with a smile.

Liu Banxian replied with a smile: "Thanks to Mr. Su's blessing, there have been five of them this morning."

No wonder Liu Banxian was so happy. There were five customers this morning, and there might not be so many in a day on weekdays.

Despite the fact that at this stage of the Ming Dynasty, there was no budding science and technology, and things like magic were prevalent, but fortune telling had never been very good.

The main reason is the popularity of Buddhism.

Compared with fortune-telling, ordinary people are still more willing to burn incense and worship the Buddha, and go to the Buddha to ask for fortune-telling.

Fortune tellers like Liu Banxian actually have a very difficult life.

Five customers a day were enough for Liu Banxian to close the stall immediately.

"The business is indeed good, but since the business is good, why not continue? Such good business does not happen every day."

Su Jing asked with a smile.

Liu Banxian walked straight into the courtyard, sat on a stone chair, put Banxian's flag against the table and said: "Master Su, everything must be done in moderation, five people a day is enough, any more is greedy, no way!" "

"Hahaha."

Su Jing smiled and said: "That's right. After all, it's about leaking secrets. If you leak too much on this day, you will easily be punished by God. I understand."

Liu Banxian said seriously: "Master Su really understands me, what he said is right!"

The two of them were laughing and talking, but Zhu Di on the side was very impatient.

Zhu Di originally thought that Liu Banxian was someone who had an irreconcilable relationship with Su Jing, so he kept silent and did not show any attitude.

But in the past two days, he also roughly knew the ins and outs of Liu Banxian and Su Jing.

Liu Banxian said he was a fortune teller, but in fact he was just a charlatan with little ability.

Listening to Liu Banxian's serious explanation, he couldn't help it anymore.

"If you are really afraid that the secret will be leaked, then why don't you just not do this business in the first place? Could it be possible that if you change your profession in the Ming Dynasty, you will starve to death."

Zhu Di looked at Liu Banxian coldly.

When Liu Banxian heard this, he was immediately unhappy and was about to scold Zhu Di, but he immediately thought of Zhu Di's identity.

"Young Master, you can't say that."

Liu Banxian said with a smile: "It is not good to leak secrets, but it can also help other people. To borrow a Buddhist saying, if I don't go to hell, who will go to hell? I, Liu Banxian, am also a person with great aspirations!"

Good guy, this Liu Banxian has directly portrayed himself as an upright and upright person who works for the benefit of the people.

Zhu Di didn't know how to refute it for a while, but he didn't agree with his theory.

Su Jing smiled and said: "Liu Banxian, your ambition is really big, but since you have big ambitions, why would you run to me?"

Liu Banxian's face paused, and he did not show any embarrassment. He smiled and replied: "Of course I am here to help Mr. Su survive the bloody disaster. This is also part of my great ambition."

Su Jing shook her head and said, "Sure enough, the saying that people become thicker-skinned when they get older is really not nonsense."

"Mr. Su, what's wrong with being thick-skinned? I also asked Mr. Su, you are the big boss of our Lishui County. Your business is so big, how could you still be thin-skinned?"

Liu Banxian reached out and poured himself a glass of water. There was no sense of restraint in Su Jing's home.

This made Zhu Di very dissatisfied. He respected Su Jing so much. This little fortune teller really didn't take Su Jing seriously.

"Don't talk nonsense here. How could Mr. Su have a bloody disaster? It's absolutely impossible!"

Zhu Di glared at Liu Banxian.

Liu Banxian replied: "Young Master, you also saw my fortune telling yesterday. I, Liu Banxian, never speak empty words. I am absolutely certain that Mr. Su will suffer a bloody disaster. I just can't predict when it will happen."

"If you don't believe me, young master, just wait and see. I'm still very confident in myself."

Su Jing looked at Liu Banxian's neither humble nor overbearing answer, and had a somewhat different understanding of this fortune teller.

Su Jing felt that even if Liu Banxian couldn't guess Zhu Di's identity accurately, he could still make a rough guess.

Ordinary people, if they knew Zhu Di's identity, would probably be so frightened that they would tremble when they spoke.But Liu Banxian was calm and calm, even so confident.

This is not something ordinary people can do.

Could it be that this guy also has some unusual identity?
Su Jing suddenly became curious.

After listening to Liu Banxian's words, Zhu Di couldn't help but think of what happened in the lumber shop yesterday.

Liu Banxian's fortune telling is still somewhat accurate.

"In that case, how do you solve Mr. Su's bloody disaster?"

Zhu Di asked Liu Banxian.

Su Jing's safety is not only his personal problem, but also the problem of the entire Ming Dynasty.

Liu Banxian smiled and said: "Young master, there are some secrets that can only be understood but cannot be expressed in words. If I tell them, it won't work."

"So please forgive me, young master, but I can guarantee that as long as I am here, Mr. Su's bloody disaster will definitely be solved."

It can only be understood but cannot be expressed in words. This statement is really a panacea.

Zhu Di's face twitched, and he even considered using his status as King of Qin to oppress Liu Banxian.

"Okay, Liu Banxian, I don't care about fate, and I don't believe in fate, so please stop selling here."

Su Jing said: "Although you are here, I will not prepare food for you."

Liu Banxian directly took out a big cake from his pocket and said: "Don't worry, I, Liu Banxian, am not the kind of person who just wants to get food for himself. I have a big cake, and I only need to ask for saliva."

Even Su Jing, a ruthless person who brought his own dry food, would not be able to easily ask the other party to leave.

"Sir, are you really going to let him stay here?"

Zhu Di looked at Su Jing and asked. He didn't want anyone else around him when he was receiving Su Jing's teachings.

Su Jing said calmly: "It's okay, he doesn't understand it anyway."

……

When Liu Banxian heard this, his face jumped. This was really a slap in the face.

But he had no choice but to stay here with Su Jing, and it was hard for him to open his mouth and say anything more.

"Yes, sir."

Zhu Di nodded and immediately stopped caring about Liu Banxian's affairs.

After a while, Su Jing finally made a simple 'locomotive'.

The structure of the main body is not much different from before, except that the mouth of the special-shaped bottle corresponds to a small wheel plate, which is somewhat similar to the wheel plate of the keel waterwheel, and the two ends of the wheel plate's central axis are two rear wheel.

Su Jing's idea is very simple, that is, water vapor pushes the wheel plate and drives the rear wheel to roll, thereby realizing the advancement of the entire 'locomotive'.

However, when the candle was lit, Su Jing realized that her idea could not be realized at all.

Because of lack of motivation.

The water vapor generated by burning water with such a small candle cannot push the wheel plate to drive the rear wheel.

The dead weight of the entire device is too great, and the buoyancy in the water can offset it a lot, and the friction on the water surface is also much smaller.

Once on the ground, you can't move forward at all.

"Sir, this..."

Zhu Di looked at the motionless 'locomotive' on the ground and wanted to ask, but felt it was inappropriate.

"It's okay. Doesn't this just show that simply mastering the principles cannot build a train?"

Su Jing immediately picked up the 'locomotive'. Without the limitation of its own weight, the wheel plates immediately began to move, driving the rear wheels to move as well.

"Did you see that the wheels are moving?"

Su Jing immediately began to explain: "The reason why it didn't move just now is actually that the kinetic energy was not enough. This engine can drive the wheels, but it cannot drive the entire car."

"The same goes for building a train. Although the principle is very simple, if you really want to build it, there is still a long way to go."

Seeing the wheels of the 'locomotive' in Su Jing's hands rolling continuously, Zhu Di's eyes shone with light.

train!

He could finally understand how the train moved.

"Mr. Su, if you want to build a train, what other knowledge do you need?"

Zhu Di couldn't wait to ask.

He was now convinced that it was possible to build a train.

Zhu Di just wanted to know how to make such powerful military strategic equipment right away.

Su Jing smiled and said: "That's too much. It can't be explained clearly in one or two days. It may not even be possible to understand it in ten or twenty years."

The steam engine in history was really widely used during the Industrial Revolution.

The appearance of trains was much later. The first train was built in 1804.

It is still more than 400 years from now.

Moreover, Su Jing also knew that the speed of the first train was surprisingly slow, only 5 to 6 kilometers per hour.

Therefore, Su Jing's ten or twenty years is already extremely exaggerated.

Zhu Di's face darkened, feeling a little disappointed. He knew that there was a means of transportation like a train, but he couldn't really see it.

Beyond the former, there will always be some troubles that ordinary people don't have.

"Okay, I've been busy for a long time, let's go wash up first."

Su Jing said to Zhu Di that he was also very tired this day.

First making bicycles, and then giving lessons to Zhu Di, it was really fulfilling.

"Yes, Mr. Su."

Zhu Di nodded, then turned and entered the kitchen.

Upon seeing this, Liu Banxian asked Su Jing: "Master Su, what is the train you are talking about? Why haven't I heard of it?"

Liu Banxian was still very concerned about what Su Jing said just now, which he couldn't understand anyway.

Originally he thought that Su Jing would not look down upon him, but after listening for a while, he realized that what Su Jing said was absolutely right.

Su Jing said calmly: "Liu Banxian, what I just talked about was science, but what you talked about in fortune telling was superstition, not all the way, so don't force it."

science?

superstitious?

Liu Banxian frowned and asked, "Mr. Su, what do you mean by this? I, Liu Banxian, tell fortunes with truth, so how can I call it superstitious?"

"And what do you mean by science?"

Su Jing looked at Liu Banxian, thought for a while and said: "Science is a secret that is completely leaked, while superstition is a secret that is hidden for fear that others will know it. Do you understand?"
