±2 t5 p , c *F 4-n L*c 5ú C Qv M =0 Steelmaking is a steel made after pig iron is repeatedly folded and beaten, and most of the carbon elements are removed by using oxygen in the air in the process, so that the carbon content is reduced to a very low standard.

Generally speaking, steel can be folded more than 100 times to become 100 steel.

But to fold and forge a piece of iron more than a hundred times is a huge and magnificent project.

According to the general casting process of blacksmiths, the weight of a sword cast by 100 steels is between one and a half catties to two catties, even if it is two catties of iron, it takes at least ten days to cast a sword with 100 steels as raw materials.

On the other hand, a blacksmith can refine two catties and one hundred steels in ten days.

Two taels a day, there are only twenty catties in one hundred days, and seventy catties can be refined in a year.

Then three years is two hundred catties!

A thousand blacksmiths count, three years is 200,000 catties of iron, these numbers are less than one thousandth of the 40,000 catties that Su Baiyi said!

It's no wonder that Mao Bijiang reacted so much after hearing it!

"When did this official deceive you?" Su Baiyi frowned, and asked in a cold voice: "You just said another word, could it be that I deceived you before, Xiao Mao, be honest, don't be untrustworthy." Beware of saying too much and losing it! ”

"Heh......" said in a hurry: "Master Su doesn't care about him, the students are just suspicious of how these thousands of people can train 40,000 catties of 100,000 catties of steel in three years, and I hope Lord Su will say it clearly!" ”

"There's no rush for this!" Su Baiyi waved his hand and said: "When I arrived in the workshop, the official naturally let you see how I smelted a hundred steels, and now, the official will talk about the issue you are most concerned about, that is, the three benefits of this railway!" ”

"Now this official will talk about the first advantage, that is, speed!" Su Baiyi took a few steps back with a microphone in one hand and a stick in the other, stopped in front of a huge display board on the right, and pointed to the display board with the stick in his hand, saying: "Fast speed, how fast is it, here I can't help but give you a clue." After a slight pause and attracting everyone's attention, he said: "From Huai'an Mansion to Xi'an Mansion, the whole journey is two thousand miles, and the train will only take two days and two nights to arrive after the construction of my railway, remember, this is the most conservative estimate, that is, it is likely to take less than two days!" ”

The speed of the steam locomotive is not as turtle as people think, it turns out that in history, the first day of the steam locomotive appeared in 1804, it was still a single-cylinder steam locomotive, burned wood, the power was very low, and it ran to a speed of 8KM/h after pulling five wagons full of goods. At the beginning of the twentieth century, when the whole steam engine technology really matured, the speed of the truck was about 60 kilometers per hour, and the passenger car was even faster, up to 80 kilometers per hour.

Su Baiyi conservatively estimated that the steam locomotive he made was based on the experience of thousands of people after all, and even if it could not reach the mature technology period of later generations, it should be better than the first horizontal bar steam engine.

Let's take a positioning of 20 kilometers per hour, so that you can run almost 1,000 kilometers in 48 hours in two days, two nights!

Of course, Su Baiyi is sure that the speed of the steam locomotive he will build in the future is more than 20 kilometers, maybe it can reach 40, but there is still the stay time of each station, the so-called seven points are full, there is just room for it!

Even so, the people below were shocked when they heard this speed!

"What? Two days and two nights? Zhu Guobi's eyes widened, and his face was incredible.

"Two days ......"

"Can it really be two days?" Kang Hui's eyes lit up slightly.

From the East China Sea to Xi'an, the road is not a smooth road, although there are not many mountains and valleys, but there are many small water systems that are constantly blocked, even if a person drives an empty carriage, I am afraid it will take half a month, if you do not take a carriage and just ride a horse, it will take at least eight to ten days.

But this truck, such a big iron bump, can get to Xi'an Mansion in two days and two nights?

"Lord Su!" Zhang Shuo of Tongguan arched his hand and asked, "According to what Master Su said, can this train be left in the dark at night?" ”

"That's nature!" Su Baiyi said: "The two rows of wheels of the train are stuck on the tracks, and the direction of walking can always only be forward, and it doesn't matter if there is light or not. ”

"Oh!" Zhang Shuo arched his hand, then looked at Kang Hui and said in a low voice: "Look, no wonder you are called Xiao Zhuge or not, don't care if you have this kind of bearing and self-confidence, who of us can match it." ”

"Lao Zhang, are you going to buy it?" Yangzhou salt merchant Gao Bin asked.

"Why don't you buy it?" Zhang Shuo said: "For us, what is 500,000 taels? Since there are people who come here and don't want to buy them, I can see that this railway, nine times out of ten, is really as Lord Su said. ”

"Hmm......" Gao Bin nodded, but he was still a little hesitant, not that he didn't believe Su Baiyi, but that Su Baiyi threw out so many novel things, he couldn't fully understand it for a while, as the saying goes, knowing oneself and knowing one's opponent is invincible, this most basic information can't be mastered, so it is indeed a little embarrassing for him to spend 500,000 taels of silver wrongfully.

"Brother Kang, what do you think?" Gobin hesitated and looked at Kang Hui again.

Kang Hui ignored him!

It's not that he ignored him, but that he didn't hear what Gobin was saying at all.

At this moment, his eyes were fixed on a large photograph of a train with billowing smoke speeding on the railway, and the smoke from the chimney was thrown behind him as the train moved, and it looked like a big monster.

"Lord Su!"

Very abruptly, Kang Hui didn't pay attention to the salt merchant Gao Bin who was waiting for him to speak next to him, but looked at Su Baiyi who was smiling at the front with a look of anticipation, and arched his hand: "Kang asks for advice!" ”

"Mr. Kang, please speak!" Su Baiyi raised his hand!

"Lord Xie Su!" Kang Hui's face turned to the huge photo of the train again: "Kang has only one question, the power of water and fire that Mr. Su said is not to boil water with fire, steam water into gas, and then rely on the power of the atmosphere to push the train to run?" ”

When Kang Hui spoke, everyone was startled, and then their eyes focused on the giant painting.

What is Atmosphere?

I'm afraid that none of the people present understand, but the atmosphere has great power, and a bowl of atmosphere is comparable to the strength of more than thirty horses, and everyone still knows this.

And it cannot be denied that only Su Baiyi in this world understands the atmosphere and can use it.

Su Baiyi's pupils shrank slightly, and he looked at Kang Hui: What a person who is observant, he can figure out a single photo with just a photo, I really don't know if I will cooperate with him in the future to build a ship, whether I will take advantage or suffer a loss?

"Hehehe......" Su Baiyi laughed, doing business with the country, even if an individual can take advantage of it, it is only a star and a half, a person's power is limited, and he can only bear the entire industrialization change, it can only be him Su Baiyi, it is this court, it is the Ming Dynasty: "Mr. Kang is not an ordinary person!" ”

Su Baiyi gave a thumbs up, but did not elaborate too much.

The train is boiled by fire and steamed, and then the power of the atmosphere is used to propel the train.

Yes, that's right!

But Kang Hui's cleverness can only go so far!

How is the train propelled and how is the power of the atmosphere used? How to make a cylinder? How do you achieve a perfect four-stroke?

There are also two connecting rods, big wheels, boilers, air pressure!

Even if Kang Hui's IQ is two hundred and five, he will definitely not be able to think of it.

"Sure enough!" Kang Hui arched his hand: "Su Zi is also talented!" ”

Everyone looked at Kang Hui suspiciously, but they didn't understand the meaning.

Mao Bijiang frowned, and suddenly had an extremely bad premonition.

Gao Bin next to him said in a low voice: "Brother Kang, what the hell is going on?" ”

Kang Hui sighed and said, "I don't know, but I'm sure that this train is walking with the power of fire and water, absolutely right!" ”

"What about you?" Gobin wondered.

"I regret it!" Kang Hui said: "I knew earlier, I should have made a move yesterday, hehe, or Mr. Gu has a unique vision!" ”

Gu Changzuo, who bought a stake yesterday, smiled.

He did buy the railroad, but it had nothing to do with his eye, he bought it because someone asked him to buy it, not because he really liked the future of the railway.

"Alright, let me talk about the second advantage!" Su Baiyi waved his hand, and after quieting the people who were coaxing below, he said, "This second advantage is: the load is more. If you ask me how much cargo the train can carry, then I can answer you now, I can pull 5,000 stone of grain in one cart, and I will reach Xi'an Mansion in two days and two nights. Moreover, it is not that my railway can only transport 5,000 stone in two days and two nights, under the normal operation of the railway, every half an hour or an hour, you can send a train, as long as the trains do not fight and collide with each other, the materials transported can be endless! Moreover, our Longhai Railway is a double line, that is, there are two lines that come and go, and they are not contradictory. ”

"What?" Gao Bin grew his mouth: "Five thousand stones, two days and two nights?" ”

It's simply unimaginable.

He has been in the salt business all year round, and what he is most afraid of is transportation, especially long-distance transportation, and every time he transports a large amount of salt, he must bring a large amount of grain with him, otherwise the roots will not be able to be transported.

"The third advantage: it is fully functional, not only can transport all kinds of goods, but also has a special passenger car to transport people, and one car can take thousands of people to travel. Hehe, for example, your home is in the East China Sea, and you suddenly want to see Huashan, okay, as long as you go to Huai'an Mansion or Donghai County first, buy a ticket at a fixed station and get on the train, you can reach Huayin Huashan in two days! If your home is in Xi'an, you want to go to Nanzhili to play, it is very convenient, just buy a ticket in Xi'an, two days later, you will go to Huai'an, from Huai'an to Nanzhili There are too many ways! ”

A train exhibition, coupled with Su Baiyi's detailed explanation on the side, especially after saying the three advantages of the train, many people are ready to move.
