Su Yongming finally went to Yuanxin Technology to work as an assistant to his father.

Yuanxin Technology has a 77-storey building in the magic city, and Su Yunxin's office is on the 76th floor, with a panoramic view of the mountains.

As Su Yunxin's assistant, Su Yongming's office is next door to Su Yunxin.

The work was very boring, everyone knew his identity, and they didn't dare to let him be busy and tired, so he yawned all morning, watching the hovering cars coming and going outside the window. In the afternoon, I simply skipped work and went to a friend's house to disassemble an old-fashioned police mecha together.

Su Yunxin didn't dare to reprimand Su Yongming on his first day at work, lest he leave in anger. It was not easy to put his son under his nose to take care of him, and he was ready to take it slowly, not in a hurry.

In the evening, Su Yongming asked Xiaoyue to collect many copies of the battery manufacturing process that were no longer protected by patent law that were circulating on the Internet, and finally selected two solutions that had been researched on the earth.

One is the lithium-sulfur battery, whose energy density is 5 times that of the earth's existing lithium batteries, and the capacity loss of the battery is very small, the service life is at least 3 times that of the lithium battery, and the lithium battery has an overwhelming advantage in cost and weight comparison.

Another option is the sodium-oxygen battery, which has also been studied by some scientific institutions on Earth, but it is not going well. Su Yongming has a mature solution at hand, and the energy density of the finished sodium-oxygen battery is almost 6-8 times that of lithium batteries.

And sodium is much cheaper than lithium, making the cost of such batteries extremely low, almost $60 per kilowatt-hour in the price of the earth world.

At present, the cost of electric vehicle batteries on the earth is about 300 US dollars per kilowatt hour, and the weight of A-class cars is about 1350-1400 kg, and about 25-30 kilowatt hours of batteries need to be installed to drive to ensure a range of more than 50 kilometers, and almost 9000 US dollars of batteries are needed from the cost calculation.

Using this sodium-oxygen battery, the cost can be reduced to one-fifth in the case of achieving the same range, and the weight of the battery itself can also be reduced to one-fifth, and the number of charging and discharging can be increased by 3 times, which can be said to achieve a seckill effect on the earth's existing lithium batteries.

And crucially, both options require materials and manufacturing processes that are achievable on Earth at this stage.

Earth, the morning of November 11, 2019 in the Gregorian calendar.

It's the annual Double 11 again, Su Yongming got up and sighed a little about his single status, and decided to ask Li Shanshan to come out at night to see if he could get off the single.

Ran downstairs to drink a bowl of bean curd, eat a corn nest nest head, he took his ID card, buy a two-color ball bill, taxi to Yunzhou City Shengli East Road Provincial Fucai Center.

After entering the door, Su Yongming looked relaxed and casually found a window and asked, "How do I redeem the prize?" ”

Behind the window was a rather beautiful girl, twenty-five or six years old, with her hair curly and permed. She didn't raise her head: "Bonus 5,000 yuan or less can go to the lottery ticket sales point to redeem the prize,100,000 yuan or less please go to the city fucai center to redeem the prize." ”

Su Yongming smiled, "I won the first prize." ”

The girl raised her head, and after glancing at Su Yongming, she thought he was joking. It's not that she hasn't seen more than the first prize, most of them are wearing masks, and those who don't wear masks are either so excited that they are trembling when they speak, or they are so nervous that they are restless. How can anyone be as calm and idle as if he was walking in a park.

After hesitating for a while, she still replied cautiously: "Please go to the prize redemption room on the second floor to claim the first prize." ”

"Thank you, Miss Wen," Su Yongming glanced at the work card on the girl's chest with satisfaction, which read "Wen Xin", and glanced at her full chest by the way, "I'll transfer 100,000 yuan to you when the meeting is finished, and tell me your card number." ”

Wen Xin's mouth grew in surprise. Her first reaction was that this guy was a madman, and after thinking about it, she thought that this guy was a liar and wanted to use her bank card number to commit fraud.

She immediately picked up the phone on the desk and dialed the phone of the security office: "Brother Liu, please come here, there is a liar here." ”

Su Yongming was stunned, and when he saw Wen Xin's eyes staring at the suspect, he was simply laughing. It was a temporary idea, and I wanted to reward this girl with a little money, as a thank you gift for her to tell herself, but I didn't expect to be treated as a liar.

He leaned on the counter, leaned forward and smiled at Wen Xin: "Beauty, you are really tall enough, I don't want the 100,000 I gave you for nothing." ”

Wen Xin glared at him, and said with a little pride: "How can there be a free lunch in the world, don't treat everyone for fools." ”

While speaking, a tall man in a security uniform had already hurried over, carrying a rubber baton in his hand, and shouted in a loud voice: "Where is the liar? ”

One sentence drew the attention of everyone in the hall.

Wen Xin pointed at Su Yongming, and Su Yongming smiled: "Brother, please take me to the prize room, I'm here to claim the prize." ”

Wen was anxious and said loudly: "Brother Liu, he is a liar, don't believe his words!" ”

Su Yongming turned around and smiled at Wen Xin: "It's good to be confident in your own judgment, but you still have to follow the procedure, right?" If you think I'm a liar, you can call the police, but since I offered to go to the prize room, you don't have the right to stop it, right? ”

Wen Xin was speechless for a while, and the security guard also hesitated, not knowing what to do. After thinking about it for a while, he still decided to take Su Yongming to the prize room first, and then ask the leader how to deal with it.

Wen Xin watched Su Yongming go upstairs and bit his lip unconsciously. Seeing Su Yongming's calm performance, she doubted her judgment again.

In the end, she decided to leave it behind. Anyway, she has already warned her, and the next thing will be a headache for the leaders.

When he arrived at the prize redemption room with a bright window, Su Yongming sat directly on the brown leather sofa, boredly turning the Viking bracelet on his wrist.

The security guard hurriedly walked into the office, and after a while, a middle-aged man with a flat head walked out with the security guard, walked straight to Su Yongming, looked at it quickly with a scrutinizing gaze, and then asked politely: "This gentleman, are you here to claim the prize?" What kind of color is it? ”

"The two-color ball," Su Yongming said, "was bought at the point of sale at 340 North Labor Road." ”

The flat-headed man suddenly shook his body. Although the news was not revealed,But they these staff naturally know,Ten days ago, at No. 340 North Labor Road, the lottery ticket sold at the Fucai sales point opened 100 Note First Prize、600Note Second Prize,And it was bought by the same person.

This is the first jackpot in the history of the lottery since the founding of the People's Republic of China! 622 million!

"Sir, I am Wang Xiping, director of the Provincial Fucai Center, please show your valid documents and lottery tickets, and I will verify them in accordance with the procedure." Suppressing his excitement, the flat-headed man said in as calm a tone as possible, but he still unconsciously brought honorifics.

Su Yongming handed over his ID card and the lottery ticket he had purchased with a big grin.

Wang Xiping was stunned for a while before reaching out to take it. Which of the lottery players he has received before is not trembling, hesitating, and even needs him to spend half a day talking before he dares to hand over the lottery ticket?

Involuntarily held his breath and glanced at the ticket stub in his hand, Wang Xiping intuitively felt that this should be true, and the handsome young man in front of him was the winner of the 622 million grand prize.

He felt that the documents and ticket stubs in his hands were hot. 622 million! This is a huge wealth that many people can't earn in a hundred lifetimes after working hard!
