Reborn Troops

Zhou Wanwan and Qianqian were both a little nervous. Xu Mei's description made them realize that the design of the necklace was far more complicated than they had imagined.

Not only does it have to look good, it also has to function in extreme environments.

"Mr. Xu, our preliminary design has been completed."

Zhou Wanwan took a deep breath and tried to make her voice sound steady.

"The main body of the necklace is a silver chain, the pendant is embedded with LED lights and micro-heating sheets, and the battery is hidden in the chain."

“We also plan to add an emergency signal light, which is not normally on and will only be activated in an emergency.”

After listening to this, Xu Mei frowned slightly, as if he was thinking about something. He was silent for a few seconds.

Then he slowly said: "The LED lights and heaters work well, but the signal lights... may not be enough."

"Not enough?" Qianqian was puzzled. "What other functions do you think are needed?"

Xu Mei tapped his fingers lightly on the map, his eyes deep. "The environment of the sand cave is more complicated than you think."

“In addition to the low temperatures, darkness and complex terrain, there are also magnetic field disturbances.

Ordinary signal lights may not be able to penetrate the rock formations. What I need is... a communication device that can work stably in extreme environments."

Zhou Wanwan's heart sank. Xu Mei's request was obviously beyond their ability. She turned to look at Qianqian and found that her expression was also a little solemn.

"Mr. Xu, this request... may be a little difficult." Zhou Wanwan hesitated for a moment, but decided to tell the truth.

"We are just jewelry designers and are not familiar with communication equipment. If we want to add such a function, we may need the assistance of professional engineers."

Xu Mei nodded, not seeming surprised. "I understand. So, I brought someone with me."

As soon as he finished speaking, the door of the store was pushed open again. A tall and thin man walked in.

He was wearing a dark grey jacket and carrying a black tool box.

He wore a pair of thick glasses on his face, and his eyes behind the lenses looked a little tired, but revealed a sense of concentration.

"This is Engineer Lin," Xu Mei introduced. "He has extensive experience in the field of communications equipment.

I invited him here in the hope that I could complete this design with you.”

Engineer Lin nodded as a greeting. He walked to the counter and opened the tool box, which contained various sophisticated instruments and circuit boards.

"Mr. Xu has already briefly introduced the situation to me." Engineer Lin's voice was a little hoarse, but his tone was firm, "The magnetic field interference of the sand tunnel is indeed a big problem.

However, I have recently been researching a new type of shortwave communication device that may be able to solve this problem."

Zhou Wanwan and Qianqian looked at each other, both a little surprised. They didn't expect Xu Mei to bring an engineer directly, and they didn't expect things to suddenly become so complicated.

"Engineer Lin, what exactly is the shortwave communication device you mentioned?" Qianqian couldn't help but ask.

Engineer Lin took out a small circuit board from the tool box and handed it to them.

“This is a shortwave frequency-based communication module that can remain stable in extreme environments.

It’s small enough to fit into a pendant on a necklace. However, it requires special batteries, and… it’s not cheap.”

Zhou Wanwan took the circuit board and looked at it carefully. Although she was not familiar with electronic equipment, she could see the precision of this circuit board.

She felt a little uneasy and couldn't help asking, "So...how much does this device cost?"

Engineer Lin pushed up his glasses and said calmly, “This circuit board alone costs about five thousand.

If you add batteries and other accessories, the overall cost may exceed 10,000 yuan.”

"Ten thousand?!" Qianqian couldn't help but exclaimed, "This... This is far beyond our budget."

Xu Mei seemed to have anticipated their reactions, and her tone remained calm: "Money is not a problem.

I can afford it. But I need you to design it quickly and make sure the necklace is functional.”

Zhou Wanwan felt a little complicated. Xu Mei's attitude made her feel more stressed, but at the same time, she also realized that the importance of this matter was far beyond her imagination.

"Mr. Xu, we...we will try our best." She took a deep breath and tried to calm herself down, "However, we need some time to adjust the design.

After all, the whole structure of the necklace might change after adding the communication device.”

Xu Mei nodded. "I understand. You can discuss the technical details with Engineer Lin first, and then adjust the design. I'll give you three days. Is that enough?"

"Three days?" Qian Qian glanced at Zhou Wan Wan with some embarrassment. "Time is a bit tight, but... we will try our best."
