Oak also shouted: "Ahhh

Chang Yufeng: "This ......"

I saw a figure on a wall, just like a mountain and flowing water.

He also flexibly adjusts the angle, such as when he is about to hit the ceiling, and when he suddenly turns around, he almost touches the edge of the ceiling, and runs forward.

Walk with the wind, and walk on the wall.

Not long after, something even more incredible happened.

He rushed to the ceiling again, and rushed over, and all at once he stuck to it, hanging upside down.

It's like driving a car, rampage through the ceiling, like entering a no-man's land. But then again, there really is no one on the ceiling, only him, and he can rush and hit as much as he wants.

It didn't take long for him to slip onto a pile of people.

Whether it was Ou Ke, Huangfu Xiaoge, Chang Yufeng or others, they all raised their heads one after another, and their faces formed parallel lines with the ceiling.

All the mouths were open, and the faces were full of surprise, even shock!

Huangfu Xiaoge couldn't help but shout: "Brother Xia Fan, you have to be careful! Don't fall!!...... It's so dangerous, how the hell did you do it?" At this, her face was full of surprise, and she couldn't help but shout excitedly: "Wow, you succeeded! But why don't you climb, it's slippery?!"

The person on the ceiling is not Xia Fan.

At this moment, he will not only become Spider-Man, but also a ghost who can go to heaven and earth in horror novels.

He carried a wall-climbing backpack and his hands were in gloves.

It's just that the gloves are more.

Previously, it had to move its hands to crawl, but now it just clings to the wall and can be sliding.

Xia Fan curled his legs, pressed the ceiling tightly with both hands, and turned on it, like an oversized humanoid.

The most important thing is -

It didn't make a single sound!

Specifically, the wall-climbing backpack he was operating did not make the slightest sound.

Xia Fan smiled at the flamboyant and shocking face below, then swung his ass again, and slid out forward-

It's about to hit the wall!

Huangfu Xiaoge couldn't help but exclaim, telling him to be careful.

Then he scurried against the wall and slid all the way down it.

It's like sliding down a slide to a smooth floor, rushing to the other wall, and sliding up again when you see that you are about to hit the wall.

And so it goes, from the floor to the wall to the ceiling......

Constantly spinning in circles, very flexible and fast, no sound has ever come out.

The people around him were already stunned, and their eyes and heads kept following him.

This is a super skater!

Ten minutes later, Huangfu Xiaoge covered his eyes.

"Ouch, I can't stand it anymore. Brother Xia Fan, you stop quickly, the shaking makes me dizzy, and my head is about to turn into paste. ”

Oak raised two fingers, pressed his temples and nodded straight and said, "Yes!!"

Chang Yufeng was completely stunned, and his face was pale.

Xia Fan laughed and slid in front of Ou.

He straightened up, handed him the wall-climbing backpack, lifted his chin and didn't speak.

Oak immediately put it on, and under Xia Fan's guidance, he quickly mastered the operation skills.

Soon he also relied on the wall-climbing backpack and quietly slid onto the wall, whatever he wanted.

He didn't dare to slide up to the ceiling, feeling like he would fall off and break his head.

But in spite of this, he was very satisfied and happy.

He slid back in front of Xia Fan, excitedly took off his wall-climbing backpack, and couldn't help but look at it over and over again.

He looked up suddenly, looking at Xia Fan's eyes shining.

"Mr. Xia, I didn't expect you to be so powerful. is still in his early twenties, but he is actually ...... actually upgraded the climbing rucksack to such a bull's nose in two or three hours. More than just ...... Quietly, you can still slide, how did you do it?

What an honorable title!!

Xia Fan was rarely modest, waved his hand and said: "The first person in Huaxia Science and Technology is far from being called, and the wall-climbing rucksack is just a small skill for carving insects." ”

Then, let's talk about the general changes.

First of all, it is caused by the motor, and when the power is instilled into the two gloves, they will be attached to the wall, which will cause a certain impact force, which will inevitably cause a louder sound, and the main solution is this problem!!"

Although so far, what Xia Fan said is nonsense.

But no matter Oak or Huangfu Xiaoge and the others, they all nodded again and again, only Chang Yufeng froze there.

"So I simply improved the glove and used the Chinese Tai Chi principle to fit it with metal balls. Through the balls, it can not only firmly attach to the wall, but also continue to move forward, and most importantly, it can dissolve the sound ...... created by the power generated by the motor."

He spoke freely for more than ten minutes, pointing out the mountains and rivers.

Huangfu Xiaoge applauded, and Ou Ke admired him so much that he threw himself to the ground.

He sighed: "I can't think of it, it's really unexpected, this is a miraculous improvement! By changing the suction surface on the glove to a ball, it not only solves the noise problem, but also greatly reduces the burden on the user." You don't have to climb up all the time, just stick your gloves to the wall and you can take it to slide freely. And with certain techniques, it can also run freely on the ceiling...... Hanging explosion!!"

"Okay, I'm going to order 3,000 sets...... No, I'm going to order 5,000 sets, you can make a price. ”

Xia Fan didn't dare to call the shots, so he looked at Huangfu Xiaoge.

The little beauty of the emperor thought for a moment, and said crisply: "In this way, Mr. Oak's original price was fifteen hundred dollars, but now it has added a double effect." Grade up ...... How about two thousand dollars?"

Oak's eyes lit up, but he didn't hesitate, and nodded again and again: "Okay, then two thousand dollars." ”

Xia Fan's eyes darkened, and he hurriedly raised his voice: "This and this...... Let's negotiate well, two thousand dollars is a bit low. After I solved the problem, it seems that there are more than ...... new features What about two thousand five hundred dollars?"

He glanced at Huangfu Xiaoge, his face full of encouragement.

Huangfu Xiaoge was taken aback by him: "What, two thousand five hundred dollars?"

Chang Yufeng couldn't help but say loudly: "Are you crazy? Who wants such a high price of 2,500 US dollars? Don't take Mr. Oak for a fool, he is willing to agree to 2,000 US dollars, and he is already very optimistic about us! Don't talk about it there, don't talk nonsense if you don't understand the market!!"

Xia Fan didn't bother to pay attention to him, so he looked at Oak.

Oak groaned slightly, smiled bitterly, and slapped his face: "Okay, Mr. Xia, for the sake of your amazing ability, you can upgrade the wall-climbing rucksack to this level in two or three minutes, I will promise you, two thousand five hundred dollars a set, and buy five thousand sets from you first." I have two small requests, though. First, the maintenance period of this batch of climbing ruffles has been extended to three years, and second, if I have to subscribe to the next batch, you have to give me a discounted price. ”

"Anyway, we're old customers, aren't we?"

Huangfu Xiaoge is surprised, often scorched on the outside and tender on the inside.

He stared at Xia Fan with resentment, turned his head abruptly and left, and had no face to stay here any longer.

Xia Fan is a big blow to him!!

How could there be such a strange thing in the world, not only obstructing him everywhere, slapping him in the face, but also making him miserable.

"You wait, I won't let you have a good time!!"

Walking out of the door of the workshop, Chang Yufeng suddenly raised his head and made a hideous sound in the air.

A bewitching figure hid behind a large tree, staring at him closely, his face full of sadness, and sighed slightly.

The Huangfu Xiaoge in the workshop didn't care much about the wind, she was already a little carried away by the powerful surprise.

Two thousand five hundred dollars, and all at once **5,000 sets, how much does it cost?

It can be said that in Xiaoge's business this year, even if this one is not the largest, it is still in the top three.

Huangfu Xiaoge was so excited that he wanted to hug Xia Fan's arm and kiss him endlessly on the face.

Huangfu Xiaoge signed a contract with Oak and received a deposit.

This will be followed by a kick-off meeting with the participation of all relevant technical staff.

Chang Yufeng said that he was not feeling well, and he had to rest well, and he couldn't come.

Huangfu Xiaoge was a little helpless.

Xia Fan was very calm: "I believe he is really uncomfortable, because he was knocked out by my slap in the face, let him rest well." After I told you the key points of the core technology, you decided whether you want to talk to Chang Yufeng or other relevant people. ”

Huangfu Xiaoge nodded straightly, very excited: "Brother Xia Fan, technology is power, in my eyes, you are really becoming more and more powerful." I'm going to give you a sum of money to buy the technical points, and it's not interesting, anyway, I'll just give you dividends. In the future, all the benefits brought by the wall-climbing rucksack will be divided into 30%!"

Xia Fan was extremely excited, sure enough, technology is power, and technology is wealth.

Taking this order as an example, after removing all the costs and giving it to him in 30%, it is an immeasurable wealth.

He felt that he was much more powerful than before, not only richer, but also the money he earned. As soon as I talk about it this time, I can let that damn Xue Tianya and all the family members know that Lao Tzu is no longer a big young master who spends all day and wine with family money!

I can make a lot of money myself, more than you!

Of course, now is not enough, we have to take it in stride.

Until you step on the sea of stars, go back and let Xue Tianya kneeling down and holding Lao Tzu's feet and licking them.

Thinking of this, Xia Fan's whole body blossomed with joy.

He smiled and said yes, and asked Huangfu Xiaoge not to worry. When all the goods are sent out, Oak will call all the final payment, and it will not be too late to divide it among him.

Huangfu Xiaoge nodded: "Okay, but Brother Xia Fan, if you are in a hurry to use the money, just tell me, and I can give you an unlimited advance here." ”

Unlimited advances, what a beautiful word.

As soon as Xia Fan heard this, he felt all kinds of big bills floating down in the sky.

"Good!!"

Huangfu Xiaoge said: "After lunch, I will take you to choose a car, didn't my grandfather promise you to give you a villa and a luxury car? There are many luxury cars in my garage, you can choose." ”

"Why do you have so many luxury cars in your house?"

Huangfu Xiaoge suddenly showed a trace of sadness.
