Reborn Troops

"I think we can use temperature-sensitive materials to achieve the color-changing effect," Engineer Li suggested, "so that the necklace can change color according to body temperature."

"What about the dynamic snowman?" Qianqian asked.

“We can use micro motors and LED lights to simulate the movements of the snowman,” Engineer Li replied, “but we need smaller motors and more efficient batteries.”

Zhou Wanwan nodded and said, "Let's split up. I'll contact the material supplier, and Qianqian, you and Engineer Li will work together to research micromotors and batteries."

A few days later, Zhou Wanwan returned to the laboratory with a batch of temperature-sensing materials.

Engineers Qianqian and Li have also made some progress. They have found a new type of micro motor that is small in size and high in power.

"Let's start making samples," Zhou Wanwan said excitedly.

However, just as they were about to take action, Engineer Li received a call from the company's senior management, asking him to return to the company immediately to deal with an urgent matter.

"Wanwan, Qianqian, I may have to leave for a while," Engineer Li said helplessly, "You guys should proceed according to the plan we discussed first. If you have any questions, feel free to contact me."

Although Zhou Wanwan and Qianqian were a little disappointed, they still nodded.

"We will try our best," Zhou Wanwan said firmly.

After Engineer Li left, Zhou Wanwan and Qianqian began the intensive production work.

They assembled the various parts of the necklace step by step according to the design drawings.

Zhou Wanwan and Qianqian were busy in the laboratory, their fingers shuttling between various materials and tools, as if they were weaving a beautiful painting.

Time passed by unknowingly, night fell, and the lights in the laboratory seemed exceptionally bright.

"Wanwan, do you think there is something wrong with the wiring of this micro motor?" Qianqian frowned and pointed at the circuit board on the table.

Zhou Wanwan put down the tools in her hands, moved closer to observe carefully, "Well, it seems something is wrong. Let's check the line again."

The two rechecked the circuit and found that there was indeed a wire connected in the wrong position.

After adjusting it, Qianqian breathed a sigh of relief, "Fortunately I found it in time, otherwise the motor might have burned out."

"Yes, details determine success or failure." Zhou Wanwan nodded in agreement, "Let's continue and try to make the sample tonight."

Just as they were about to continue working, Zhou Wanwan's cell phone rang again.

She glanced at the screen and saw that it was Master Zhongshan calling.

"Hello." Zhou Wanwan answered the phone with a hint of fatigue in her tone.

"Wanwan, how are you progressing?" Master Zhongshan asked with concern.

"We are making samples and have just solved a small problem." Zhou Wanwan briefly reported the situation.

"Very good, but I have a new idea that may further improve your design." Master Zhongshan's voice was filled with excitement.

"Teacher, please speak." Zhou Wanwan immediately perked up.

“I suggested adding some tiny crystals to the snowflake part of the necklace, which would create a shimmering effect under the light and make it more attractive,” Master Zhongshan explained in detail.

Zhou Wanwan's eyes lit up, "Teacher, this is a great idea! Let's try it right away."

After hanging up the phone, Zhou Wanwan immediately told Qianqian about Master Zhongshan's advice.

The two decided to take a break from their work and began to study how to incorporate crystals into snowflake designs.

"We can use laser engraving technology to carve tiny grooves into the snowflakes and then embed the crystals into them," Qianqian suggested.

"Good idea, but we need to find suitable crystal materials." Zhou Wanwan nodded in agreement.

The two immediately began searching for relevant materials online and eventually found a suitable tiny crystal. They contacted the supplier and ordered a batch of samples.

A few days later, the crystal samples arrived, and Zhou Wanwan and Qianqian couldn't wait to start the experiment.

They first used a laser engraver to carve grooves into the snowflake model, and then carefully embedded the crystals into them.

"Look, it really sparkles under the light!" Qianqian excitedly showed their work.

Zhou Wanwan also showed a satisfied smile, "It's so beautiful, the teacher is indeed a master."

Zhou Wanwan and Qianqian worked hard in the laboratory, and the production of the necklace progressed smoothly.

However, just as they were about to take the final step, they encountered a problem.

"The color change range of this temperature-sensitive material is not wide enough, and our necklace can only display limited colors." Zhou Wanwan said distressedly.

Qianqian frowned and thought for a moment, then suddenly an idea came to her mind: "We can try to use a mixture of multiple materials, so that we can expand the range of color changes."

Zhou Wanwan's eyes lit up and she immediately began to look through the materials, looking for suitable materials.

After some research, they decided to use a mixture of three different temperature-sensitive materials.

"Is this method really feasible?" Zhou Wanwan asked with some concern.

Qianqian smiled confidently: "Trust me, it's okay."

After some intense experiments, they finally found the best mixing ratio.

The color variation range of the necklace has been greatly expanded to meet their design requirements.

Just then, Master Sun Yat-sen walked into the laboratory.

"You two little guys, thank you for your hard work." Master Zhongshan said with a smile.

"Master Zhongshan, you are here." Zhou Wanwan and Qianqian immediately stopped their work and greeted Master Zhongshan.

Master Zhongshan looked at the necklaces in their hands and exclaimed: "Your progress is amazing. The design of this necklace is really unique."

Zhou Wanwan said modestly: "We are still far from it, Master Zhongshan, can you help us see if there is anything that needs improvement."

Master Zhongshan looked at the necklace carefully and said, "Your design is already very good, but I can give you a suggestion to make this necklace even more perfect."

Zhou Wanwan and Qianqian immediately pricked up their ears and listened carefully to Master Zhongshan's advice.

Master Zhongshan said: "You can add a dynamic pattern of changing seasons to the pendant of the necklace, which can better reflect the theme of the necklace."

Zhou Wanwan and Qianqian smiled at each other. They thought Master Zhongshan’s advice was great.

"Master Sun Yat-sen, you are such a genius!" Zhou Wanwan said excitedly.

Qianqian also said excitedly: "Let's start designing right away!"

So, Zhou Wanwan and Qianqian immediately started designing dynamic patterns of changing seasons.

After some hard work, they finally designed an exquisite dynamic pattern of changing seasons.
