Cultivation in the city

Duan Xiaolou and Chen Yan did not immediately go to the place Zeng Fan and the others said to test and register after returning, probably because they had already made preliminary contact with them, and they also believed that they did not reject or dislike the ability group. They were also very tolerant and understanding.

Duan Xiaolou's third year of high school summer vacation has not yet ended, and Duan Xiaolou's grades don't have to worry about further studies. He should have been very idle, but Zhang Wenya's new vacuum cleaner has been well received. time was spent on my own research.

Regarding vacuum cleaners, Duan Xiaolou has done some research. The principle is relatively simple, but many modern techniques have been designed. Not to mention that he does not have core technologies. Even if he does, he may not be able to make products that surpass Zhang Wenya’s .

He also asked Duan's father that Duan's Tiancheng Electric used to make vacuum cleaners. What was advertised was not as practical as those old-fashioned cleaning tools, so after a period of time, it was discontinued due to poor sales.

When Dad Duan talked about the vacuum cleaner he produced, his tone was full of regret.At that time, he was still young and full of energy. He originally wanted to use the vacuum cleaner as a trump product to enhance the company's image. Unfortunately, the technology was not strong enough to achieve what he wanted, and because the investment in the vacuum cleaner was too large, the company was hindered. , I almost couldn't catch my breath.

The reason why Duan Xiaolou is more concerned about the research of vacuum cleaners is, on the one hand, to compete with Zhang Wenya, and on the other hand, to fulfill his father's dream of a vacuum cleaner.

Although Dad Duan didn't mention Tiancheng Electric much, every time he talked about it, he would be full of nostalgia and sentimentality. It can be seen that in his heart, no matter how big the business is now, it can't make up for Tiancheng Electric's bankruptcy. He brings regret.

During this period, the Chen family urged Chen Yan several times, and Chen Tai'an even bluntly said that if Chen Yan didn't come home again, he would not recognize him as his son.It's a pity that such words have no deterrent effect on Chen Yan. He still does his own thing, but after Mr. Chen tried to persuade him a few times, Chen Yan agreed without pain, but there was no change at all.

Gradually, the Chen family didn't care much about Chen Yan's affairs, and only told the family to remember to go back and show their faces when they get together during the holidays and festivals, and just don't leave anything to those reporters. Chen Yan agreed very readily this time.

Duan's father and Duan's mother did not dislike Chen Yan because they had lived at home for a long time. Instead, they seemed to be in love with Chen Yan, and they became more and more considerate to Chen Yan.

They all noticed Chen Yan's care for Duan Xiaolou. Although they never said it clearly, they already regarded him as half a son in their hearts.

If it weren't for the fact that the Chen family's business was too big and too complicated, Mother Duan would even want to find a god-in-law.It's a pity that the Chen family was too chaotic, so Mother Duan had no choice but to give up the idea.

Chen Yan became more and more comfortable in Duan's house. He talked with Duan Tiancheng in the study about the progress of Duan Xiaolou, and Duan Tiancheng was so moved that he almost rushed to the laboratory to give Duan Xiaolou a bear hug.Immediately afterwards, he went to help Duan Anran with his homework, and successfully received a look of gratitude mixed with admiration.Because Duan Yiqing was not at home, Chen Yan couldn't get in touch with each other smoothly, but he and Duan Yiqing have always been friendly and harmonious, and it's the same when the other party comes back to make up.Finally, he went to the kitchen, talked about his love for yesterday's dinner, and ordered a dish by the way, and then, under the loving gaze of Mama Duan, he walked towards the laboratory with the cocoa cookies and fruit tea that the other party had already tested go.

On the way there, he also put a needle through Grandma Duan, and turned down the volume of the radio for Grandpa Duan who was already asleep.

Entering Duan Xiaolou's laboratory, Chen Yan put the tray on the table and poured himself a cup of fruit tea.

Then he sat comfortably on the sofa, eating slightly bitter cookies while drinking sweet and slightly sour fruit tea, feeling very uncomfortable.

Duan Xiaolou buried himself in his own business and ignored Chen Yan's arrival.

He took the vacuum cleaner-like thing off the test stand, as if he was going to try the effect.

I saw him turn on the switch of the vacuum cleaner and point the flat suction nozzle at a cloud of ink on the ground. The ink was quickly sucked into the vacuum cleaner, leaving only a light layer of black marks on the ground. Because of this, a floor mat not far away also tends to be sucked over.

Seeing that the situation was not good, Duan Xiaolou quickly turned off the vacuum cleaner.He looked at the floor mat that had been sucked to less than ten centimeters in front of the flat suction nozzle with some sorrow, as if the other party had given him a great grievance.

Chen Yan was a little funny. He walked over and pulled Duan Xiaolou to the sofa to sit down, and by the way, he stuffed a cookie into the other's mouth.

Duan Xiaolou was chewing on the cookies, his cheeks moved like a little mouse stealing food.

Seeing that his brows were still tightly furrowed, Chen Yan couldn't help comforting him: "Too much suction can only prove that the things you make are effective. Although the effect is too good, it is also a trouble, but at least it shows that your idea is feasible, doesn't it? "

Duan Xiaolou shook his head and said: "No matter what, things that are not practical and cannot be promoted are worthless failures."

Chen Yan understood Duan Xiaolou's meaning, he thought for a while, and said: "I remember you made a broom for Auntie Duan with a spell of wind, and the effect was better than ordinary vacuum cleaners. Why didn't you continue the idea this time?" ?”

Duan Xiaolou took a sip of fruit tea, put down the teacup and explained: "The broom with the Qingfeng spell rune last time was easy to use, but it took me a day to carve the rune. It looks like a relief, but it is useless for ordinary people to carve the same pattern. It must be infused with spiritual power like me to have an effect. And the broom is not used for a long time, even if it is turned off every time it is used up, mother It was completely useless after only one month of use.”

Duan Xiaolou also thought about using the Qingfeng Curse, after all, the broom was highly praised last time, but considering the above problems, this idea could not be realized after all.

After hearing this, Chen Yan asked: "The original Qingfeng Mantra doesn't work, so have you thought about simplifying it? I don't want the effect to be as good as the Qingfeng Mantra, but the description is simpler, the threshold is lower, and the energy consumption is less. Can it be done? ?”

Chen Yan's question seemed to open the door to Duan Xiaolou's new world. He was a little annoyed why he didn't think of this, and he couldn't wait to carry out the next experiment.

He was pressed by Chen Yan and ate two more biscuits and drank half a cup of fruit tea before he was allowed to continue the experiment.

Standing in front of the test bench, Duan Xiaolou still seemed to be suppressed by Chen Yan. He concentrated on drawing the runes of the Qingfeng Mantra with various materials, and then used the same material to draw different styles of Qingfeng Mantra runes. There is a momentum that will not give up if you don't play this rune to death.

Chen Yan shook his head helplessly, randomly found a novel on the nearby bookshelf, and read it contentedly.

On the third day after Chen Yan put forward his opinion, Duan Xiaolou finally made a breakthrough. He created a rune pattern, which is similar to the effect of the Qingfeng Curse, but much weaker, and he does not need to draw it himself. Just splicing according to the pattern he provided.In terms of energy consumption, it is also much less expensive than the Qingfeng Mantra.

However, although the energy consumption is small, Duan Xiaolou still needs to continue to study the ability to supplement this.

When he was making a broom for Mama Duan, he developed a converter that stores and converts electrical energy into other energies for runes to use. However, this converter cannot be used multiple times and can only store a certain amount of power.Of course, he was also affected by the size of the broom at that time, so he didn't develop a more efficient energy storage conversion device.

Now, the vacuum cleaner does not have such a big limitation. Duan Xiaolou can completely make the conversion device bigger, and even remove the storage function of the converter and change it to a mode that can be charged at any time.

Of course, it is up to Duan Xiaolou to decide what kind of finished product will be. He can even make these types of vacuum cleaners and split them into different series for sale.

While Duan Xiaolou was making vacuum cleaners, his acceptance letter had already been sent home.He did not apply for foreign universities, but filled all the local schools. Of course, his first choice—Central Continent University—was finally accepted.

Central Continent University is one of the best in the country, and Duan Xiaolou does not need to go to other places to study, Duan's family is very happy, Duan's mother even started planning to buy Duan Xiaolou a house close to the school, so that they can visit and take care of her.

But Mama Duan's idea failed to come true in the end, because Chen Yan had already bought a house there in advance.

Since Chen Yan already had a property there, the Duan family also felt that there was no need to buy another one there.It can also be seen from this that the Duan family really treats Chen Yan as their own family.

Duan Xiaolou's research on vacuum cleaners was finally basically completed before the start of school.

The vacuum cleaner he made is similar to the hand-held stick vacuum cleaners on the market. Dad Duan took a closer look, and it seemed that the main body was removed from a vacuum cleaner he bought for Duan Xiaolou some time ago.

It's just that the plastic dust box for storing garbage at the front of the vacuum cleaner has become a black box hanging on the back, and the plug has also changed from the side of the vacuum cleaner handle to the top of the black box.

At first glance, this vacuum cleaner seems to be lacking in aesthetics, but Duan Xiaolou's tools are limited after all, this kind of problem that can be solved by design is not a problem for Duan Tiancheng at all.

The Duan family looked at Duan Xiaolou without blinking. They were fully prepared and were waiting for the "moment to witness the miracle"!

Duan Xiaolou plugged the plug into the power supply under the expectant gaze of the crowd, and then turned on the switch.

There was a loud "bang", a spark exploded from the plug, and Duan Xiaolou stood there stupidly, the vacuum cleaner in his hand did not respond at all...
