On this day, from the completion of the preliminary test at noon to the evening dinner, Qin Yunfei has already drawn countless design drawings in the laboratory, but there are many deviations in each design drawing.

Yes, it is easy to change from high voltage to low voltage, but it is troublesome to change from low voltage to high voltage, and the most troublesome thing is that you can output stable enough high-voltage electricity.

The design drawings for Ling Qi were originally not intended to use hundreds of thousands of volts of ultra-high pressure, so there was no entanglement in this.

However, since he had agreed with Long Jun that he wanted to make a bet with her, how could he defeat the enemy if he had to deal with those Soul Venerable level thunder powerhouses, without a volt voltage starting at 100,000?

"In the previous world, it was possible to increase the pressure of the boiler to achieve tens of millions of volts, but in just half a month, it was impossible to increase the boiler. So, how can we ensure the stability of the voltage?"

Qin Yunfei fell into a tangle again, how can the three alternating currents achieve stable boosting?

While he was racking his brains to think, the door of the laboratory was suddenly pushed open.

Lin Feixue slowly walked in with a bowl of shredded meat noodles.

"Yunfei, it's time for dinner. ”

Qin Yunfei casually said "oh", then looked at the design with the noodles and began to eat.

His serious appearance made Lin Feixue feel very relieved in her heart, but deep in her heart, she was even more heartbroken.

When a man puts in work or cultivation, he is the most handsome, but which woman is willing to see her man tossing her body like this day and night?

"Yunfei, there are still miles of time, you better rest for a while, after eating, let's continue to work, okay?" Lin Feixue stepped forward and stroked Qin Yunfei's shoulder with concern.

At this time, Qin Yunfei lamented, "Every inch of time is an inch of gold, now there are only three days left before the agreement, if I can't achieve a stable voltage boost, I will definitely not be able to win." What should I do then?"

Lin Feixue thought for a while, and then asked, "Outside, there are so many batteries, when the time comes, if the batteries are connected in series, maybe they will be able to reach the target voltage you said?"

Lin Feixue's reminder made Qin Yunfei suddenly brightened.

"yes! I didn't think of this idea!"

As he spoke, he stood up suddenly, hugged Lin Feixue in his arms, and smiled excitedly, "Feixue, you are really a genius! Why didn't I think that when I made up the voltage, I could just make the current correction directly from the source of the current?"

Qin Yunfei is talking about electric power engineering, although Lin Feixue has a preliminary knowledge, but has not yet learned the stage of practical electrical engineering, so when Qin Yunfei said this, he was also a big one, and he didn't figure it out at all.

However, seeing Qin Yunfei's serious appearance, she also smiled happily, "Since this is the case, can you eat noodles with peace of mind?"

Qin Yunfei nodded happily and said, "Well, of course, have you eaten?"

Lin Feixue lamented, "You have so many batteries outside, but the charging cable is not enough, it is full of this, I have to change which one, I have not been idle in the afternoon." Did you say I ate it?"

The more Qin Yunfei looked at it, the more he liked it, so he let her sit on his lap and stomach, and took chopsticks to clip a piece of meat for her.

"My good flying snow, you are the greatest hero today! Come on, come on, I invite you to the most delicious pork belly in the world!"

Qin Yunfei fed Lin Feixue like this for the first time, and when Lin Feixue saw it, her heart was beating fast and her face was flushed, but she was extremely excited and liking, stretched out her head slightly, and was about to eat this piece of pork belly.

However, as soon as she opened her cherry mouth, a scream came from outside the door, "What are you doing!"

Qin Yunfei raised his head in astonishment, while Lin Feixue stood up from him suddenly, at this time, he lowered his head and didn't even dare to raise his head.

And Qin Yunfei looked out of the door in embarrassment, but saw that Ye Linghua was looking at them in embarrassment at this time.

"Sister Linghua, why are you here?

In order to avoid embarrassment, Qin Yunfei hurriedly diverted the topic.

Ye Linghua's face turned pale at this time, and he was going to have a seizure, but after thinking about his current identity, it was inconvenient.

She snorted and said, "I came to ask you to eat, and you have all eaten." ”

As she spoke, she glanced at Qin Yunfei with resentment, as if to say, "I know you have a good relationship, but you don't have to perform like this in front of me, right?"

However, the more she was like this, the more embarrassed Qin Yunfei became.

"Well, Feixue said she didn't eat either, so didn't I ask her to eat with me? ”

When Qin Yunfei explained, he smiled awkwardly, obviously trying to please Ye Linghua and ask her not to step on her little tail and continue to torture the two of them.

Who knows, this Ye Linghua suddenly said angrily, "Oh, she didn't eat it, you can eat like that? I didn't eat it either!

Qin Yunfei was afraid that women would be jealous, so when he encountered this kind of problem, he was immediately dumb and silent.

Lin Feixue said something on the side, "No one stopped you......"

She didn't say that it was okay, as soon as she said it, the more atmosphere this Ye Linghua was, she held the dishes and chopsticks, stepped on the breath, and walked to Qin Yunfei in less than two steps, without saying a word, she sat directly on Qin Yunfei's lap.

"Okay! Then I'll eat like this! Yunfei, you come and feed me!"

As he spoke, Ye Linghua didn't say a word, he opened his mouth and asked Qin Yunfei to feed him.

Qin Yunfei said embarrassedly, "You don't have to do this, right?"

Ye Linghua shouted domineeringly, "Why don't you use it?"

At this time, Lin Feixue also sat on Qin Yunfei's lap again, and she even hooked Qin Yunfei's neck with her hand.

"I promised you that we would compete fairly! However, Sister Ling Hua, you are going too far!

In this way, the two women sat on their laps and had to feed them by themselves, which really embarrassed Qin Yunfei.

"Well, you've made my legs numb, why don't we go out to eat together?"

Qin Yunfei's embarrassing proposal, jealous of women, he was really fed up.

However, as soon as he spoke, these two big beauties shouted in unison, "Shut up!

Originally, I wanted to protect both sides, but now it seems that I am really going to suffer.

Sure enough, just after Qin Yunfei knew the result, Ye Linghua was already holding the bowl, and said with a smile on his face, "Okay! Okay, I won't let Yunfei feed me, I'll feed him!" Yunfei opened his mouth, ahhhh......h

Seeing that Ye Linghua wanted to feed Qin Yunfei noodles in person, Lin Feixue was not to be outdone, and hurriedly followed to deliver the meat slices.

"Yunfei, you eat me first, open your mouth, ah......"

Just when Qin Yunfei was in a dilemma, there was a sudden sound of chopsticks falling from outside the door.

The three of them turned their heads to look, but saw Su Xinghe looking at them in a daze, and after about three seconds of embarrassment, Su Xinghe immediately covered his eyes and ran out.

"Oops, my soup splashed in my eyes, I didn't see anything......"
