The mechanical box is one foot square, the material is just ordinary star iron, and although the forging technique is exquisite and sophisticated, it can only be regarded as an upper-middle level in Nie Bing's eyes.

The highlight of MicroOne is the magnetic field effect created by the wire vein structure, which acts on a mechanical ball the size of a ping-pong ball in the mechanical box, making the ball rotate in the void, like a satellite surrounding the earth, which is a good idea.

It's just that every time the ball turns halfway, it shakes its body and falls. At the bottom of the box is a conical bottom, when the ball falls on the cone point, it is slowly pushed up by the surrounding magnetic force, only to fall again halfway through, and the cycle repeats.

Sidney sat across from him, his gaze never taking off Nie Bing's expression.

This box looks simple, but it is not an ordinary thing, and its scientific name is the gravitational space vortex box.

It is possible to produce an effect similar to that of gravity and magnetic fields around the poles. It can be counted as an independent gravitational space.

And he took out this, firstly, to test Nie Bing's technical level, and secondly, he recently received an ultra-difficult project.

Although dozens of well-known god refiner experts from several surrounding planets were gathered to discuss and conquer together, there was no good way to solve it. Seeing that the construction period was coming, they did not have the most appropriate plan, and forced construction at that time, I was afraid that the consequences would be unimaginable.

And the ball in this box represents the engineering thing they designed, how to make the ball follow the gravitational orbit, circle normally, and not fall halfway, this is the difficulty they want to overcome.

"Does the president want me to put this little ball on the right track?"

Nie Bing looked at it for a while, and he already knew it in his heart.

From Earth to Mars, and then to Jinyun Star, along the way, he has touched and practiced space folding nodes, which one is not related to magnetic field gravity. It wasn't really a difficult question for him.

"Oh? If Brother Nie can answer, please use your means to open my old man's eyes. ”

Sidney's eyes lit up and he sat up straight, his eyes faintly expectant.

Nie Bing nodded, not talking nonsense.

As soon as the palm of his hand was flipped, the aura of gravity was shrouded in the mechanical box, and the entire office trembled for a moment, Sidney's breath was also suffocated, and his eyes were a little more awe-inspiring when he looked at Nie Bing.

Knowing that this was still Nie Bing's deliberate restraint of the power of his ability, otherwise his office would be stripped of his skin.

Snort! The light of the power of Vientiane flashed into the mechanical box, like a mysterious vine, stretching out and penetrating into the veins of the texture of the star's iron.

A round of virtual roulette appeared in the internal space of the mechanical box, and the void trajectory of the original ball rotation lit up the track line at this moment.

The magnetic orbital line that relies on the structure of the star's iron vein is turned into a clear entity, and the small ball is like a machine on the orbital line, running step by step. It's just that when it reaches the fork in the road ahead, the ball will be stunned and fall stiffly.

"Condensation!"

Seeing that the mechanical ball had come to a fork in the road again, Nie Bing's wrist shook, and all the magnetic field segments in the entire mechanical box space seemed to have been cast a space-time freeze magic, and all of them stood still.

I saw Nie Bing's eyebrows raised, and the power of Vientiane instantly turned into a pair of dexterous little hands, building blocks to rearrange the originally flat magnetic field lines, and at the same time, the mechanical balls were also broken down into miniature parts.

The hair-delicate veins of the iron texture of the stars were pulled out of the mechanical ball, and the small hands of the power of Vientiane were arranged in a braid, and a set of magnetic wires opposite to the external mechanical box were framed.

From Nie Bing's point of view, the magnetic track in the mechanical box and the magnetic wire in the ball are like a pair of mother and daughter, holding hands with each other, forming a companion and interdependent structure, revealing a mutual foam, glue-like attraction.

"It's ......"

Sidney on the other side stood up, and the scene he saw was slightly different from Nie Bing's.

It was a pair of colorful butterflies that were about to fly, and the magnetic tracks circled around each other, passing through each other and intertwining with each other, but each line segment maintained a precise distance from each other, slowly running on its own trajectory.

Especially just now, Nie Bing actually built a magnetic orbit in the opposite direction inside the small ball.

As the so-called repulsion of the same sex, opposites attract, the interior of the planet is also divided into two pole magnetic fields, at the beginning they only focused on the magnetic field space of the mechanical box, and completely treated the mechanical ball as a dead thing.

Even though some Divine Refiners had proposed to set up corresponding tracks inside the ball, no one had ever thought that the real principle was like this.

Sidney felt a cheerful heart, as if Nie Bing had opened a window in his mind. Looking at Nie Bing again, his attitude seemed to be a little restrained.

Although Nie Bing didn't explain anything or speak, it was the technical display at that moment just now that it was already an unpassed secret in the inheritance technique.

And as the head of the Divine Refiner Guild, no matter how stupid he is, he knows that he has suffered great benefits.

Airplanes!

The mechanical box shook slightly, and unlike before, which only lit up one virtual roulette, the mechanical box lit up two rounds of virtual roulette.

Nie Bing retracted the aura of gravity and the power of Vientiane. The small ball in the mechanical box began to quietly rotate around the void trajectory in the mechanical box.

This time, not only did the ball show no signs of falling, but it also cycled along several different trajectories from time to time, and the most peculiar thing was that the ball could also rotate for a certain amount of time.

"Mr. Nie, thank you for your guidance."

Sidney straightened his shirt and bowed respectfully to Nie Bing.

"President, don't you dare to be a ......"

Nie Bing hurriedly got up and stretched out his hand to help Sidney, but at this moment, there was a click outside the door, and the sound of a small metal object falling to the ground.

"Who? Get the hell out of here. ”

There was someone peeping outside the door, which made Sidneyden angry, he really wanted to befriend Nie Bing now, but he didn't expect to make a mistake at this juncture.

Squeak!

The door opened, and a figure with a pale face and a whole body like chaff squeezed in through the crack in the door.

"President, Nie, Mr. Nie......"

Poof, the figure finished shouting, and as soon as his legs went limp, he fell to his knees, and in his hand he held a golden badge high above his head, unable to speak again.

"Is that you?"

Nie Bing saw at a glance the person kneeling on the ground, and the middle slit on his head was the middle man who went through the membership procedures for him.

"Li Di, have you been outside all the time just now?"

Sidney's face sank, and he stepped in front of Li Di in one step, and the endless coercion was like a mountain suppressing it. Just now, all his thoughts were on Nie Bing, and he didn't care that anyone dared to peep outside his room.

"Yes, you will listen to me, President."

Li Di trembled and said: "Just now I came to send the certification card and badge, see that your door is closed, but there is light from the crack in the door, curious I took a look at the crack in the door, I didn't expect Mr. Nie to show his might, scared me to the point of urine, as soon as my hand slipped, the badge fell to the ground, I was really unintentional." Even if I borrow eighteen guts, I won't dare to peep into your room, and I will grow up to be a wise man. ”

Li Di was almost prostrate on the ground, and he didn't dare to look at Sidney at all, he was really afraid of angering Sidney and being slapped in the face.
