Reborn Troops

"But..." Qianqian wanted to say something, but was interrupted by Zhou Wanwan.

"We will definitely find a solution." Zhou Wanwan said.

Just when they were about to give up, Zhou Wanwan suddenly had an idea.

"Qianqian, do you still remember the transparent tape we saw when we went to the technology exhibition last time?" Zhou Wanwan asked.

"Transparent glue?" Qianqian was stunned for a moment, "You mean the transparent glue that can be used to glue various materials together?"

"Yes!" Zhou Wanwan said excitedly, "If we use this transparent glue to fix the luminous material on the bracelet, maybe we can solve this problem."

"Good idea!" Qianqian's eyes lit up, "Then let's try it quickly!"

Zhou Wanwan and Qianqian excitedly came to Professor Sun's laboratory with their newly invented voice-controlled luminous bracelets.

Professor Sun is a materials scientist they met at a science and technology exhibition. He was very interested in Zhou Wanwan and Qianqian's project and agreed to help them further improve the bracelet.

"Professor Sun, look, this is the bracelet we designed." Zhou Wanwan handed the bracelet to Professor Sun, her eyes flashing with anticipation.

Professor Sun took the bracelet, looked at it carefully for a while, and then nodded slightly.

"Yes, your design is very creative. However, I need to test its performance."

"Of course, please go ahead." Qianqian said with a smile.

Professor Sun took out an instrument and began to perform various tests on the bracelet.

Zhou Wanwan and Qianqian stood nervously by the side, holding their breath, waiting for the result.

"Well, the stability of the luminous material is pretty good, and the voice recognition system is basically working."

Professor Sun said as he was testing, "However, I noticed a problem."

"What's the problem?" Zhou Wanwan asked anxiously.

"The battery life of the bracelet is not ideal." Professor Sun frowned. "If the user uses it for a long time, the battery will run out quickly."

"What should we do?" Qianqian was a little anxious. "We finally solved the problem of luminous materials. Are we going to be stuck on batteries again?"

"Don't worry, I have an idea." Professor Sun pondered for a while, "We can try to use a new type of rechargeable battery. This battery is small in size and has a high energy density. It should be able to meet your needs."

"Great!" Zhou Wanwan breathed a sigh of relief, "Then when can we start?"

"Tomorrow, I'll prepare some samples for you and you can try them first," said Professor Sun.

The next day, Zhou Wanwan and Qianqian came to Professor Sun's laboratory again. Professor Sun handed them several small battery samples.

“These batteries charge very quickly and can be cycled many times.”

Professor Sun explained, "You can modify the battery compartment of the bracelet a little bit, and it should be able to fit in."

"Thank you so much, Professor Sun!" Zhou Wanwan said gratefully.

"You're welcome. I'm glad I could help you." Professor Sun said with a smile, "But I have another suggestion."

"What suggestions?" Qianqian asked curiously.

“Although your bracelet is very creative, the appearance design can be improved.” Professor Sun said, “Young people nowadays not only pursue functionality, but also pay attention to aesthetics.”

"You're right." Zhou Wanwan nodded, "We really need to work harder in this area."

"I know a very talented designer who may be able to help you," Professor Sun suggested.

Chapter 3: Design and Challenges

Zhou Wanwan and Qianqian returned to their studio with great expectations, bringing the new battery samples provided by Professor Sun. They immediately began to modify the battery compartment of the bracelet.

"Wanwan, how difficult do you think it will be to modify this battery compartment?" Qianqian asked while fiddling with the internal structure of the bracelet.

"It shouldn't be too difficult," Zhou Wanwan replied, "Professor Sun has given us very detailed instructions. As long as we follow his advice, we should be able to complete it smoothly."

The two of them divided the work, Zhou Wanwan was responsible for dismantling the original battery compartment, and Qianqian was responsible for measuring the size of the new batteries to ensure that they could be perfectly embedded in the bracelet.

"Look, this battery is the perfect size," Qianqian said excitedly, "We just need to slightly adjust the internal structure of the battery compartment and it should fit in."

"Great," Zhou Wanwan breathed a sigh of relief, "This way, our bracelet's battery life problem is solved."

However, just when they thought everything was going well, problems arose.

"Wait, Wanwan," Qianqian suddenly frowned, "Look here, the connector of the new battery doesn't match the original one."

Zhou Wanwan leaned over to take a look, and sure enough, the shape of the new battery interface was completely different from the original one.

"What should we do?" Zhou Wanwan was a little anxious. "Do we have to redesign the circuit again?"

"Don't worry, let's calm down first." Qian Qian took a deep breath, "Maybe we can ask Professor Sun again to see if there is any solution."

The two decided to put aside their work for the time being and go to Professor Sun's laboratory again.

"Professor Sun, we have encountered a problem," Zhou Wanwan said straight to the point, "The interface of the new battery does not match the original interface, and we don't know how to solve it."

Professor Sun took the bracelet, examined it carefully, and nodded.

"Well, this is indeed a problem," Professor Sun said, "but don't worry, I have a solution."

"What plan?" Qianqian asked anxiously.

“We can use an adapter,” Professor Sun explained, “Is this adapter okay?
