"If you succeed, you will succeed. You will also learn from Iron Man to show off!"

Just as Qin Lu expressed his feelings in his heart, a brain collapse occurred on his forehead.

"Me, where did I show off?" Qin Lu, who was pulled out of his memories, looked at Qin Xue with a grievance and said.

"I said no, I just got a battery, I can do it!" Qin Xue looked at Qin Lu, with a slight jealousy in her voice.

"Hahaha, it turns out that you are jealous of my master's talent, hahaha..." Qin Lu laughed happily.

"You're talking nonsense..." Qin Xue's pretty face turned red. She was immediately shy when she was exposed to her thoughts and raised her fist to hit Qin Lu.

Qin Lu pretended to hide and gave her a few punches from time to time. The two of them stopped after a half-minute fight.

"Hey, to be honest, you are really amazing. How did you think of using these materials?" Qin Xue sat on the stool, leaning on the test bench, looking at Qin Lu with her head, and asked curiously.

"There is only one secret--" Qin Lu stretched out his hand and pushed his glasses that did not exist, stretched his finger forward, and the dead elementary school student was immediately possessed.

"Hurry up and say, I just imitated the Iron Man, and now I am imitating Conan again!" Qin Xue picked up a glass stick in her hand, with a stern face and said.

"Okay, okay, I'll say!" Qin Lu smiled, and then his face suddenly became very serious.

"The real secret is..." Qin Lu said this, paused for a moment, and then said quickly.

"Read more, read more newspapers, eat less snacks and sleep more!"

After Qin Lu finished speaking, he looked at Qin Xue quietly and waited for her to speak.

"It seems that there is something to be said..." Qin Xue turned her head and thought for a while, and said seriously.

"Forehead……"

Qin Lu didn't expect that he would trick his goddess of wisdom by saying a random word.

It seems that Qin Xue, who is rumored in the world, has high IQ and EQ, which is just rumors...

Qin Lu nodded in his heart and then turned his attention to research.

A large battery capacity does not mean a fast charging speed. At the same charging power, the current flow rate is the restriction of the maximum charging speed of the battery.

"It's a pity that there is no graphene, otherwise, I can still experiment!" Qin Lu shook his head a pity and sighed.

There is not a single graphene at Xijing Jiaotong University. Such a top university has all kinds of chemical reagents.

However, graphene costs 5,000 yuan per gram, which is extremely expensive. Qin Lu and the others naturally cannot borrow it. Unlike these ordinary materials, graduate students from Xijing Jiaotong University can even make it themselves.

Moreover, the special procurement department has cooperative relationships, which are very cheap, far cheaper than the market price.

However, there are only a few manufacturers across the country who can make graphene, clearly marked the price, whether you want it or not, you don’t want it, and others will pay high prices.

Therefore, Qin Lu still plans to take the industrial chain after he goes back and does it himself.

What's more, a 10,000 mAh battery can be used for one day at high strength and can be charged for more than half an hour, and consumers won't care.

Moreover, Qin Lu started to take out the first one, which was the first-class battery with a capacity of more than 8,000 milliampere hours. Many of the latter ones were used by Qin Lu's own products in the future.

As for selling technology?

Qin Lu is not that stupid yet.

He used existing materials in the laboratory to make a charger. After installing the chip on the battery with a capacity of more than 8,000 milliampere hours, Qin Lu clamped it onto a professional testing instrument.

"I'll go, the battery with a capacity of more than 8,000 mAh, the 15v3a charger can be filled in one hour and twenty minutes, right?" Qin Xue's big watery eyes were almost glaring out.

She looked at the data on the instrument in disbelief, then looked at Qin Lu and said.

"There are still flaws. This conductive material is still a bit bad. However, it is enough to take it out as the initial product!" Qin Lu said with a smile.

"My God..." Qin Xue was numb.

"Okay, let's withdraw. The task is completed. Let's go and invite you to dinner!" After Qin Lu's hand, he operated the computer to completely delete the laboratory data, including the underlying files, and some other equipment operation records were eliminated to the point where they were as low as possible.

Even Qin Lu washed the remaining materials in the material tank cleanly with acid and alkali to ensure that they could find only the most ordinary iron ions.

Finally, Qin Lu passed everything in his mind, and after confirming that there was no mistake, he left with the stupid Qin Xue.

Until downstairs of the girls' dormitory, Qin Xue was still stunned.

"Hey, sister, go up and take a shower. I'll go back to the hotel house to take a shower. Let's go to have a meal!" It's inevitable that the battery will be stained with some acid and alkaline, and the smell is quite strong. It doesn't matter to Qin Lu, but Qin Xue is a girl who loves to be stinky and beautiful.

"Okay, stand here and wait for me. I'll be quick, five minutes!" Qin Xue was afraid that the time she said was short, so Qin Lu ran away and went upstairs in a flash, bringing his former president of Taekwondo club to the extreme.

Qin Lu smiled bitterly, walked to the garden and sat down, waiting for Qin Xue.

Since Qin Xue said for five minutes, it would definitely not exceed twenty minutes.

As someone who has had a girlfriend, Qin Lu knows the time it takes for girls to dress up.

After going upstairs, Qin Xue picked up her shower utensils and rushed into Duwei. In less than five minutes, she took a rough shower.

Then, he opened the cabinet like crazy, turned out his underwear, skirt, etc., and put it on his body randomly. He didn't even have time to look at the mirror, so he rushed downstairs. The whole process was less than ten minutes.

When Qin Lu saw Qin Xue, who had wet hair and two different colors of socks appeared in front of him, he was amused and crying.

"Sister, I can understand that you don't blow your hair. After all, you have good physique and are not afraid of colds. I have no objection to the inappropriate matching of skirts and tops. After all, you look good in whatever you wear with beautiful people!" Qin Lu looked at Qin Xue helplessly and sighed.

"But, your socks are always red, and a pink one really hurts your image!" Qin Lu sighed and said.

"Ah..." Qin Xue finally reacted, lowered her head and looked at her feet, and rushed into the dormitory building with a whoosh.

"Take it slow, I'll wait for you!" Qin Lu shouted with a wry smile, and then smiled helplessly again.

After Qin Xue went upstairs, she quickly changed her socks and then carefully checked them.

The skirt was not worn in reverse, the top was tied up, the color of the underwear would not leak out, the buttons were buttoned up, and the safety pants were worn...

After confirming that there was no problem, Qin Xue checked her shoes again before she went downstairs with blushing and came to Qin Lu.

"Okay, you are my sister, you have to be the demeanor of being a sister, do you know?" Qin Lu rolled his eyes, reached out to pat Qin Xue's shoulder, and then the two of them walked towards the house that Qin Lu opened!

He brought Qin Xue to the room, Qin Lu quickly took a shower, and then blew Qin Xue's hair at the same time, and the two of them went to have a meal.

After experiencing the wrong socks, Qin Xue finally came out of her shock.

After eating, they found that it was less than three o'clock, so the two made an appointment to go to a nearby park.

In the park, two people walked side by side, almost two people carved from the same mold. Outsiders saw that they were brothers and sisters or siblings.

There was even a cute little girl coming up to ask if the two were twins, and Qin Xue explained with a smile.

As for the boys in the school, they were blinded by jealousy.

"It seems that we look quite similar!" Qin Xue said with a smile.

"We are brothers and sisters, how can we not be like each other!" Qin Lu also smiled and touched the little girl's head, watching her walk away by her parents.

"By the way, since you have developed this thing, what are you going to do? Find someone to invest or sell technology?" Qin Xue asked.

"Not even, I'm going to open a company by myself and cooperate with those mobile phone manufacturers to build batteries!" Qin Lu said with a smile.

"But, will they agree?" Qin Xue asked with a frown.

"In this world, as long as there is the first person to eat crabs, there will be a second and third..." Qin Lu smiled confidently. Since he came back fifteen years later, he knew many things and naturally could grasp the loopholes and intervene.

"Okay, then I'll wait for you to get rich and support my sister..." Qin Xue joked.
