Douluo see you

Chengying has traveled through so many days, and there is no sign of awakening Golden Finger. Helpless, he can only recognize the reality, and everything is achieved by his own strength.

He who has read two Douluo books is very clear that Tian Meng is a completely weak chicken, and in the end it has no fighting power. It has not been able to fight for a hundred thousand years in a million years. It is difficult to expect to become strong in cultivation. .

However, Chengying also thought about it. He didn’t have anything else, but he had a lot of time. Ten thousand years gave the soul beast the most, that is, the cultivation became stronger. But for him, don’t talk about building a Gundam or an interstellar battleship. , It’s okay to build a few aircraft carriers.

Backed by an aircraft carrier battle group, even if a hundred thousand-year-old soul beast dared to pick up trouble, his mother would not know him.

Therefore, Chengying set up a small shop in Tiandou City, starting with the simplest things. An industrial system cannot be supported by one person, but a set of basic scientific enlightenment ideas can be supported by him alone. Can be compiled.

But before that, he must first let people experience the charm of science, and to do this requires some tricky things.

...

On the main street of Tiandou City, a small store called Science and Technology Commodity City opened up someday. The owner neither issued flyers nor solicited business, and there were not even a few goods on the container.

The only thing that attracts attention is the huge glass window in the shop. Such a large piece of glass, even if it is not seen in the palace, is installed in such a deserted shop. The pedestrians passing by can only sigh the violent thing. .

However, people are curious after all. This shop has been here for several days and finally welcomed its first customer. The visitor was dressed in a silk robe. Although there was no embroidered mark, it can be seen that it is a family. Noble, only these people will step into Chengying's shop out of curiosity.

Entering the store, he felt cool for some reason. As soon as he entered 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. Be responsible for……"

He could understand every word of the lecture, but he didn’t know what it meant when connected together. He was arrogant that his knowledge was not much worse than those of famous scholars, but he didn’t understand the knowledge of the shopkeeper at all. I became a little more interested in this store, and coughed gently to remind the two in the store.

Cheng Ying, who was telling Dugu Bo about the characteristics of human blood, was stunned for a moment, and then he realized that a guest had come to Dugu Bo, and said to Dugu Bo: "Let’s talk about it today. You can sort out what you have learned in the past few days." Faced with the guests, seeing that the visitors were well dressed, no Jiahui couldn't help raising his eyebrows.

"Dare to ask what the guest officer is called?"

"Just call me night!" Cheng Ying's elegant smile made Cheng Ying thoughtful, and the nobleman of Heaven Dou City, who claimed to be Ye Ye, is at this age. Is it possible that he will be the future Emperor Xue Ye?

Chengying was just guessing, but didn't say anything, whether it was the future emperor or not, had little influence on him.

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

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

Ye Wenyan smiled: "Say your colored glaze shelf is even more valuable!"

"If you have to buy caskets and return beads, this counter is not impossible to sell." Chengying also laughed.

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

"Then I have to ask the owner to introduce your pearls."

When he said that, he picked up a small bright silver tin box and opened the lid. He thought there was a rare gem in the box, but he didn't want a cluster of flames to suddenly burst out of the box and startled him.

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

Ye also understood what Chengying meant. Such an exquisite lighter must be very valuable. The poor can't afford it, and the nobles have servants who can't use it. The only function is to use them to pretend to be when they go hunting.

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

"It's similar to the previous one. It's also used for ignition. This is called a match." Said Chengying took over the matchbox and nodded at night. If this thing is cheap enough, it is a good thing.

It’s just that Chengying quickly dispelled his thoughts: “This thing is still produced by me by hand. The cost is too high. People don’t have a hobby that needs to wipe the fire frequently. At best, it is just a plaything. Nothing else can compare."

Speaking, Chengying drew out a match, broke the head of the match, and said, "White phosphorus, a new kind of poison, which is almost lethal in my hand."

Chengying's words made Ye couldn't help taking a step back, and his gaze at the match was no longer a plaything.

"Don't worry so much. If you accidentally eat it, you may survive gastric lavage and vomiting." Although Chengying said so, Ye still looked solemn.

It's not that he has never seen the poisonous, but it is also a blood seal, like this kind of poison that will kill you if you eat such a little bit, it really can't let people not be afraid.

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

"What is this again?"

Cheng Ying took off the glass cover, took out a match, lit the wick below, and suddenly, the bright light was released from the wick, which was very clear even in the daytime, much brighter than the candle.

"The kerosene lamp, if you think it's too bright, you can turn this gear to adjust it." As Cheng Ying turned the gear two times, the light became like a candle.

"This is quite interesting. It doesn't need to cut candles, and it is brighter. If you are willing to sell in large quantities, there should be many big families coming to you to buy." Ye seems to be very interested in kerosene lamps: "But what does it burn? It will never light up out of thin air."

"The kerosene lamp naturally burns kerosene. A barrel of gold soul coin is not expensive! I will sell it! If you want to buy the manufacturing technology of the kerosene lamp, you can also sell it." Cheng Ying smiled slyly.

"You know how to do business. Kerosene lamps are a one-shot deal, but kerosene can flow slowly, but a bucket of gold soul coin is not expensive."

A gold soul coin is probably enough for an ordinary family of three to save money and spend a month, but it is really nothing to a large family. Although kerosene lamps can also make money, they are somewhat insignificant at night, even kerosene. He is very interested in the method of extraction.
