Chapter 69

After giving the police officers a simple explanation of the working principle behind the alarm device, Ding Chen sighed and said, “Those people are definitely not ordinary hooligans. They really want to cause death. I saw them taking out their knives. If it wasn’t for the sudden ringing of the alarm, causing them to be stunned for a while and buying me time to dodge, I might have already been stabbed in the stomach by someone.”

“I knew it. If it wasn’t an especially serious danger, your dot wouldn’t have turned into such a bright orange-red color!”

Huo Tian anxiously walked around Ding Chen. “Are you sure you didn’t suffer any other injuries? If you’re injured and not coming clean with it, I’ll tell Mom on you!”

“Your uncle isn’t a fool. If I was injured, I would definitely go to the hospital for treatment. Why would I hide my injuries?” Ding Chen was a little amused and also a little touched. He reached out and touched his niece’s hair. “What’s up with that little dot you mentioned?”

Huo Tian obediently let her uncle pet her a few times. She took out her phone and opened the alarm device’s app. “My phone is connected to the alarm device that you and Mom have. Usually, the dots that represent each of you are all green. If you encounter an ordinary level of danger, they will turn yellow. If you encounter a very serious danger, they will turn red.”

The two police officers were also listening to Huo Tian’s explanation and nodding while listening. They were still holding Ding Chen’s sensors in their hands and flipping it over and over, looking at it non-stop.

In the end, the police handed the sensor device to Ding Chen, then pulled Huo Tian to ask, “Student, your uncle just said that you made this alarm device yourself. Is there a way to mass-produce this?”

Huo Tian nodded. “It should be possible to mass-produce it. Uncle and Uncle Zhu are the ones in charge of this aspect. I’m not too sure about the exact situation.”

When Old Zhu and Ding Chen heard the police’s inquiries, they exchanged glances with each other excitedly. They quickly took the opportunity to step forward and interject, “This police officer, our Tiantian is still a student and her responsibilities are only her studies and research. Things like patent applications and mass production of products are what this Boss Zhu and I are jointly responsible for.”

Ding Chen spoke confidently in front of the police in all seriousness, but even the scar on his lips could not hide his excitement. After all, he had already sensed from the police officers’ attitude how popular the alarm device would be after it was introduced into the market.

The slightly older police officer sighed wearily. “Perhaps you hadn’t noticed it before, but we know that although society has improved, there are still many violent incidents that will result in death. Girls, especially, are easily exposed to danger.”

The other police officer added, “Some girls will be tailed by bad people when they walk at night. Some girls who live alone will encounter burglary. Even some girls who go out for a morning run might go missing. When they’re discovered again, they’ve already become a corpse… If your alarm device can be mass-produced, it’ll probably give those girls a chance of survival.”

This was a very heavy topic and everyone fell silent.

After a long while, Huo Tian said gloomily, “This is just an alarm device that can make loud noises. Actually, it doesn’t deal much damage. If we really encounter brutal criminals, this alarm device won’t be able to fend off their invasion.”

Huo Tian still wanted to add some damage-inducing functions to the alarm device, such as releasing electric currents or tear gas when danger was detected.

However, when she interacted with Bi Ying and Si Huan previously, both of them stopped Huo Tian from having such dangerous thoughts. Si Huan even gave Huo Tian a criminal law book the next day, instructing her to remember those laws well.

Although Huo Tian was filled with disdain when she received this gift, she still flipped through the criminal law book. She also understood that it was impossible to make alarm devices into lethal weapons. Therefore, she didn’t voice her thoughts in front of the police.

However, the police officers only thought that the reason Huo Tian was unhappy was that the alarm device couldn’t protect all the victims. The police liked the sense of justice she showed and consoled her with a smile. “There’s nothing perfect in this world. Even if the alarm device you sell can only save one person, it’s still worth it for the victims and us police.”

“Student, you’re doing an amazing thing. We’ll thank you for everything you’re doing on the behalf of those who might be harmed…”

The police officers left with the troublemakers, but Huo Tian’s mind kept replaying what the middle-aged police officer said at the end.

She was feeling very complicated right now. She felt joy from being acknowledged, but she also felt at a loss as to what to do when someone thought too highly of her.

However, overall, it felt wonderful to be thanked with a sincere attitude.
