Douluo See You For a Long Time

Chengying has traveled through so many days, and there is no sign of awakening the golden finger. He has no choice but to recognize the reality, and everything has been realized by his own strength.

Having read two Douluo books, he knows very well that Tianmeng is a complete weak chicken, and he has no fighting power in the end. He can't fight for a hundred thousand years after a million years. It may be difficult to expect to become stronger through cultivation. .

But Chengying also thought about it, he didn’t have anything else, but he had a lot of time. In 10,000 years, the most for soul beasts is to cultivate and become stronger, but if you give him, let’s not talk about creating Gundams or interstellar battleships. , It is no problem to build a few aircraft carriers.

Backed by an aircraft carrier battle group, even if a hundred thousand year spirit beast dares to come and make trouble, he can still fight. His mother doesn't even know him.

So Chengying set up a small shop in Tiandou City, starting from the simplest things. A set of industrial systems cannot be supported by one person, but a set of basic scientific enlightenment ideas is something he can do alone. can be compiled.

But before he could do that, he had to make people appreciate the power of science, and to do that would require some ingenuity.

...

On the main street of Tiandou City, a small shop called Science and Technology Small Commodities City appeared someday.

The only thing that attracts attention is the huge glazed window in the shop. Such a large piece of glazed glass has never been seen even in the palace, but it is installed in such a deserted shop. Passers-by can only sigh a waste of money. .

However, people are curious after all. This shop has been open here for several days, and finally welcomed its first customer. The visitor was dressed in a silk robe. Nobles, only these people would step into Chengying's shop out of curiosity.

Entering the store, he felt cool for some reason. As soon as he stepped into the store, he heard a young male voice: "Human blood cells can be roughly divided into three types, red blood cells, white blood cells, and platelets. These three types of cells are respectively Responsible……"

He could understand every word of the lecture, but he didn't know what it meant when they were put together. He boasted that his knowledge was not much worse than those famous scholars, but he didn't understand what the shopkeeper said at all. He was a little more interested in this store, and coughed lightly to remind the two people in the store.

Cheng Ying, who was explaining the characteristics of human blood to Dugu Bo, was stunned for a moment, and then realized that a guest had come to the door, and said to Dugu Bo: "Let's talk about this for today, and you can sort out what you have learned in the past few days." Facing the guests, he raised his eyebrows when he saw that the visitor was well-dressed and without any Ka Fai.

"May I ask what the guest officer's name is?"

"Just call me Ye!" The young man's elegant smile made Chengying think deeply, the nobleman of Heaven Dou City who called himself Ye, and at this age, could it be the future Emperor Xue Ye?

Chengying just guessed, but didn't say anything. Whether he is the future emperor or not doesn't have much influence on him.

"What? Why don't you tell me what you sell in this store?"

"As you can see, the shelves are full of goods." Cheng Ying pointed to the glass counter.

Ye Wenyan smiled: "If you say that your glazed shelf is more valuable!"

"If you insist on buying a pair of pearls to return, it's not impossible to sell them at this counter." Cheng Ying also laughed.

Ye thinks that Chengying is a very interesting person, and what he said is also very interesting. Although I have never heard of this idiom, I can easily understand its meaning.

"Then it's time to ask the shopkeeper to introduce your pearls."

As he spoke, he picked up a small bright silver iron box and opened the lid. He thought it was a rare gemstone, but he didn't expect a cluster of flames to burst out of the box, which startled him.

"As you can see, the lighter is still a useless toy for the time being.

But when the tobacco smoked by those tribes in the south came over, it became useful. "

Ye also understands what Chengying means. Such an exquisite lighter must be very expensive. The poor can't afford it, and the nobles have servants who can't use it for lighting.

Putting the lighter back to its original place, he picked up a small cardboard box and shook it. There seemed to be a few wooden sticks inside: "What is this?"

"It's similar to the previous one, and it's also used to light a fire. This one is called a match." As Chengying said, he took the matchbox and rubbed it. The bright fire made Ye nod his head. If this thing is cheap enough, it's a good thing.

It’s just that Chengying quickly dispelled his thoughts: “I still produce this thing by hand, the cost is too high, and people don’t have a hobby that needs to be frequently lit, it’s just a plaything at best, but this white phosphorus match is a bit Nothing else compares."

As he spoke, Chengying pulled out a match, broke off the match head and said, "White phosphorus, a brand new poison, is almost lethal in my hand."

Chengying's words made Ye couldn't help taking a step back, and the eyes she looked at the matches were no longer looking at the playthings.

"Don't worry so much. If you accidentally eat it, you can still survive by gastric lavage and vomiting." Although Cheng Ying said so, Ke Ye still looked serious.

It's not that he's never seen a poisonous poison before, but it's also a blood-sealed throat. It's hard not to be afraid of such a poisonous poison that can kill if you eat such a small amount.

"Forget it, if you don't like matches, just look at this." Chengying took out a glass jug and handed it to Chengying. Below the glass jug was a metal jar with a metal gear on it.

"What is this?"

Chengying took off the glazed cover, took out a match, and lit the wick underneath. Immediately, bright light was released from the wick, which was very clear even in the daytime, much brighter than a candle.

"The kerosene lamp, if you think it's too bright, you can turn this gear to adjust it." Chengying said and turned the gear twice, and the light became like a candle.

"This is really interesting. You don't need to cut candles, and it's brighter. If you are willing to sell a lot, there should be many big families coming to you to buy." Ye seemed to be very interested in kerosene lamps: "But what does it burn? ? It won’t light up out of thin air.”

"The kerosene lamp naturally burns kerosene. It's not expensive for one gold soul coin and one barrel! I'll sell it right away! If you want to buy the manufacturing technology of the kerosene lamp, you can also sell it to you." Chengying smiled slyly.

"You know how to do business. Kerosene lamps are a one-shot deal, but kerosene can be used for a long time. However, a bucket of gold soul coins is not expensive."

One gold soul coin is probably enough for an ordinary family of three to live frugally for a month, but it is really nothing for a big family. Although kerosene lamps can also make money, they are somewhat despised at night. He is very interested in the refining method.
