Reborn Troops

Zhou Wanwan shook her head: "No, I have always used ordinary sandpaper and polishing cloth."

Master Zhongshan smiled and said, "Micro grinding wheels can process surface details more finely, especially for areas that require high-precision grinding. You can give it a try."

Zhou Wanwan nodded gratefully: "Thank you, Master. I will prepare it now."

Master Zhongshan waved his hand and said, "Don't worry. I have some suggestions. Although the dynamic structure you designed is ingenious, the rotation speed of the stars seems a bit uneven. You can consider adding some micro springs between the gears to adjust the rotation speed."

Zhou Wanwan listened carefully and nodded from time to time. Master Zhongshan continued: "In addition, the magnetic control between the stars and the moon also needs to be optimized. You can try to use a dual magnet structure, one to control the direction of the star's rotation, and the other to control the rotation speed."

Zhou Wanwan listened attentively, and suddenly her mind became clear. She said gratefully: "Master, your advice is so valuable. I will definitely make improvements."

Master Zhongshan smiled and nodded: "Young people, it is good to be creative, but you must also pay attention to details and the accumulation of technology. Jewelry design is an art and a science, which requires continuous learning and practice."

Zhou Wanwan nodded solemnly: "I understand, Master. I will continue to work hard."

Master Zhongshan stood up and prepared to leave: "Well, I have other things to deal with, so I won't stay any longer. I hope to see a more perfect work when I see you next time."

Zhou Wanwan and Qianqian sent Master Zhongshan to the store door and watched him go away.

After returning to the store, Zhou Wanwan immediately began to make improvements according to Master Zhongshan's suggestions.

She first bought a micro grinding wheel and carefully polished the surface of the moon. The result was much better than before.

Then she adjusted the gear structure and added micro springs to make the stars' rotation more uniform.

However, just as she was about to take the final step to optimize the magnetic control, she encountered a new problem.

Although the direction of the star's rotation has stabilized, the speed of rotation has become difficult to control. Sometimes it is fast, sometimes it is slow, and sometimes it may even stagnate.

Zhou Wanwan frowned and felt pressured again.

She tried many methods but still couldn't solve the problem. Just when she felt helpless, Qianqian came over.

"Wanwan, what's wrong?" Qianqian asked with concern.

Zhou Wanwan sighed: "There is a problem with the magnetic control, and the rotation speed of the star is unstable."

Qianqian thought for a moment and said, "How about we ask Master Zhongshan for advice?"

Zhou Wanwan shook her head: "The master has helped us a lot, I don't want to trouble him anymore."

Qianqian patted Zhou Wanwan's shoulder: "Don't worry, Wanwan. Let's think about it, there will definitely be a solution."

Zhou Wanwan nodded and decided to try again.

She carefully checked the installation position and magnetic strength of the magnet and found that the problem might be due to the uneven magnetic force of the magnet.

So she decided to try using a different type of magnet to see if that would solve the problem.

After many experiments, Zhou Wanwan finally found the right combination of magnets.

The stars' rotation speed became stable and smooth, as if dancing gracefully in the night sky. Zhou Wanwan looked at herself in the mirror, her eyes sparkling with excitement.

"Qianqian, we succeeded!" Zhou Wanwan shouted excitedly.

Qianqian came over after hearing the sound, and when she saw the effect of the necklace, she couldn't help but exclaimed: "Great, Wanwan, you really did it!"

However, just as the two were immersed in the joy of success, Zhou Wanwan suddenly discovered a new problem.

Although the stars rotate smoothly, the surface of the moon will have slight color differences under different light, affecting the overall beauty.

"How could this happen?" Zhou Wanwan frowned and felt pressured again.

"Don't worry, Wanwan, we'll think of a solution." Qianqian comforted.

Zhou Wanwan nodded and decided to readjust the design. She began to study how to deal with the chromatic aberration of the moon's surface and tried various materials and methods.
