Zhang Ning took a deep breath, calmed his troubled mind, and asked, "What is that Z substance?" ”

Ji Ruyan shook his head and replied, "I don't know very well, it is said to be a substance that can break the conservation of energy!" ”

If it is true as Ji Ruyan said, then Z matter should not appear in this world, once it appears, the world will be out of order, from ancient times to the present, I don't know how many domestic and foreign physicists have studied the conservation of energy. Pen, fun, and www.biquge.info

There are many scientists who have invented perpetual motion machines, but without exception, they all ended in failure. A perpetual motion machine is just a fantasy and can never succeed, just like plants and animals, it cannot be immortal. As for the reason, it violates one of the most common laws of nature, that is, the law of energy transformation and conservation.

But if there really is a substance that can break the conservation of energy, then all of the above is possible. Perpetual motion machines will exist, plants will not wither, and humans will gain eternal life.

Although eternal life was once the dream of many emperors, it would be a terrifying nightmare for modern humans.

"Miss Ji, take the liberty of asking, who are you? Why know so much! Ji Ruyan is obviously no longer an ordinary person, Zhang Ning asked the doubts in his heart.

Ji Ruyan took out the ID card he showed at the police station before and said: "My identity on the surface is a professor at Fenghai University, but in fact I am the leader of the Huaxia Special Operations Group, if you have something, you can come to Fenghai University to find me." ”

After telling his identity, Ji Ruyan no longer cared about anything, but said to Zhang Ning: "I can't hide it, I found Mr. Zhang this time to get Mr. Zhang's help!" ”

After hearing so much, Zhang Ning's heart of a strong woman was a little nervous: "What can I do?" ”

The two talked for a long time, Ji Ruyan was about to get up and leave, stretched out his hand and said with a smile: "It feels weird to call a big beauty like you, Mr. Zhang, in the future, I will directly call you Zhang Ning, I hope the cooperation is happy!" ”

Zhang Ning smiled reluctantly, nodded and said, "Happy cooperation!" ”

The cooperation that the two talked about was that Ji Ruyan would help Zhang Ning return to the Elegance Group and let her continue to serve as the chairman of the Elegance Group, while Zhang Ning needed to conduct an investigation in the company and provide Ji Ruyan with clues to the secret plan.

Although this is very difficult, as long as you have the heart to investigate, you can find out some things, and Zhang Weiguo must have left some clues during his lifetime.

Yu Fei has been busy building a company these days, he found a location and rented a storefront, because the location is not very good, and the rent is not so expensive, about 1,080 a month. Yu Fei directly signed a one-year contract with the landlord.

After several twists and turns, Yu Fei's maintenance company was also established, and the name was Feiyang Home Appliance Maintenance Center.

The establishment of a home appliance maintenance company, Yu Fei had this idea the day after he got the all-round assistant, and after so many days of application, Yu Fei also understood what the function of the all-round assistant probably was.

First, the all-round assistant is a new intelligent product to help the host improve its maintenance capabilities, generally speaking, if you want to get assistant coins, you must apply this ability.

Second, the all-round assistant is also a tool used in life assistance, which can help the host perceive the danger, and then remind the host to prevent it, and can also help the host analyze the problems encountered.

Thirdly, the Almighty Assistant has an assistant shop, and the shop has skills that can be purchased with assistant gold.

After comprehensively analyzing the capabilities of the all-round assistant, Yu Fei knew that he wanted to obtain a large amount of assistant gold coins, so establishing a home appliance maintenance company was the only shortcut.

Of course, this is also a good thing for Fei, first, he can use the ability of the almighty assistant to earn money, and second, while earning money, he can also get assistant gold, so as to buy skills in the assistant shop, and then improve his ability.

On the second day after the establishment of the Feiyang Home Appliance Maintenance Center, Yu Fei had business at the door.

After helping a housewife fix the washing machine, Yu Fei got fifty points of assistant gold, although it was not much, but over time, it would be no problem to empty the items in the assistant's store when the time came.

At noon, Yu Fei's classmate, Liu Yingjun, called and said: "Yu Fei, if you are free in the past two days, you can go to Fenghai Mall, and the staff there called, saying that there is a problem with the central air conditioning, you should go over and take a look as soon as possible!" ”

Yu Fei has signed a contract with Liu Yingjun's home appliance store, and the approximate content of the contract is that Liu Yingjun will pay Yu Fei a monthly salary of 10,000 yuan every month, and Yu Fei will ensure the after-sales service of Liu Yingjun's home appliance store.

Although Yu Fei is a single commander, his current work is much better than before, although he is a little tired, Yu Fei is not a person who is afraid of tiredness. Yu Fei's current career has two advantages, first, freedom of work, and second, a high salary.

Let's not talk about Liu Yingjun's after-sales service with a fast monthly salary of 10,000 yuan, Yu Fei can also help others repair household appliances while doing after-sales, which is charged separately. For example, Yu Fei helped the housewife fix the washing machine, and Yu Fei charged her eighty yuan for labor fees.

Fenghai Mall is a shopping mall that mainly buys clothes, with a total of five floors, and after coming here, Yu Fei found the staff.

The staff was very polite and handed Yu Fei a cigarette, Yu Fei did not refuse, although he usually does not smoke, but he does not like to smoke, but there are three younger siblings at home who want to go to school, and he wants to save that money.

The staff took Yu Fei to the place where the central air-conditioning host was placed, and said with some displeasure: "This air-conditioner has only been used for half a year, but I didn't expect there to be a problem so soon!" ”

Yu Fei started the all-round assistant and quickly found the key to the problem, he smiled: "Technology products are like this, if you are lucky, you will not have any problems if you buy and use it for a few years, if you are unlucky, there will be problems in one or two months!" ”

The staff didn't say much, he explained to Yu Fei the problem of the air conditioner and left.

Because Yu Fei has an all-round assistant, unlike other repairmen, he does not need to use a multimeter to test the fault. Because after activating the all-round assistant, Yu Fei can see the fault as long as he relies on his own eyes.

In Yu Fei's sight, there were three red dots, that is, there were three problems, he took out the repair tools and began to get busy.

An hour later, when Yu Fei finished finishing, the staff also came over, and after starting the air conditioner, he couldn't help but breathe a sigh of relief when he found that everything was normal, and he politely sent Yu Fei to the door of the mall.

After Yu Fei came out, he called Liu Yingjun and said directly: "Old classmate, the air conditioner here in Fenghai Mall has been repaired!" ”

Liu Yingjun over there was stunned, "So fast?" ”

Yu Fei smiled faintly and said, "When you called me, I happened to be free, so I came over!" ”

After Liu Yingjun hung up the phone, after the staff on the Fenghai Mall side confirmed it, they were very happy, and secretly said that the cooperation with Yu Fei this time was still very beneficial to themselves. Since Yu Fei can repair the central air conditioning of Fenghai Mall so quickly, it is enough to prove two points, first, Yu Fei's repair technology is excellent, and second, Yu Fei is not the kind of person who is lazy and procrastinating.

While Liu Yingjun was happy, Yu Fei was even happier than him, because after Yu Fei repaired the central air conditioning of Fenghai Mall, he was reminded by the system.

Congratulations to the host for earning 100 Helper Gold!
