"Super Mosquito Boy" can drive a computer to make sounds of the same frequency as the mosquito's natural enemy dragonflies, bats, or male mosquitoes, thereby achieving the purpose of repelling mosquitoes.

While there was no class in the morning, Li Tianzong came to the library for the first time to go to the meeting website and checked the relevant information.

The function of "Super Mosquito" was not beyond his expectations, but there were many skeptical sounds on the Internet, believing that the sounds emitted by dragonflies and bats belonged to ultrasonic waves, and computer speakers are designed based on the human hearing range and cannot emit ultrasonic waves.

Seeing this, Li Tianzong couldn't help but cough dryly. He picked up the throat soggy tablet he just bought and contained one. The computer could not emit ultrasound, and probably not people could do it.

Even if he could, he didn't plan to try it casually. He shouted the day before yesterday. It was still hard to speak now. If ultrasound was emitted, the vocal cords might be torn apart.

Li Tianzong checked the Bluetooth information again.

Bluetooth is a radio technology for short-distance communication. In essence, it is a way and path for information transmission. Using Bluetooth, data transmission and communication can be achieved. If the device supports it, wireless control can be performed, such as using a wireless mouse and keyboard, which can perform all normal operations on a computer.

In the process of wireless control, Bluetooth plays a role only in information communication, just like the wired mouse and keyboard connecting the computer cable. The control itself also depends on the equipment at both ends, including hardware and software. Bluetooth itself has nothing mysterious.

Li Tianzong took a look on Baidu online and found that there are many software downloads such as "mobile Bluetooth spies", "bluetooth snipers", "super Bluetooth spies", and similar special equipment purchases and sales.

After looking at the introduction of these software, Li Tianzong discovered that what Li Changhao did today was actually not magical. The more difficult part might be password cracking. After that, it was like using a remote control to control the phone, and there was no technology at all.

Li Tianzong was a little scared when he thought about it. Fortunately, the software was damaged and could not be read. Otherwise, Li Changhao would not control a mobile phone, but his head.

Li Tianzong quickly downloaded several Bluetooth spyware to USB drive, and his consciousness seemed to be unable to see the specific situation in his brain. These software might be fine.

The existence of Bluetooth is equivalent to building a bridge between his brain and the outside world. It may allow him to see the situation inside, and there are also hidden worries because others can also come in through this bridge.

He was also trying to turn off the Bluetooth interface, otherwise everyone could use Bluetooth to connect his "brain". Even if there is no password, it would not be able to crack it. Those messy scans and request messages were enough for him.

After downloading several software, Li Tianzong checked it again, then turned off the computer and prepared to get off the computer.

Once the software is available, I don’t know if it’s easy to use. Now I just need to find a mobile phone and connect to Fan Xiaoxiao’s mobile phone, or the Bluetooth port that exists in my brain through Bluetooth.

"Li Tianzong!"

As soon as Li Tianzong paid the money, he walked out of the computer room and heard someone calling him. Looking in the sound, he saw two girls slowing down and walking over not far to the left.

The taller one has long hair that is over the shoulder, slightly yellow and slightly curly, making her look white and delicate, full of femininity, delicate and charming.

Li Tianzong recognized this girl, Wang Xiyi, the class monitor of the 091 class of the MACC, and his roommate Liang Jialiang have been talking about it, saying that she is the recognized class beauty, department flower, and hospital flower among this class, as well as of course, school beauty candidates and one of the most powerful competitors.

Wang Xiyi is indeed beautiful. She puts a simple light purple short-sleeved T-shirt on her body, which is also the convex place where it should be concave, and the slim figure is looming.

Light blue jeans wrapped around a pair of slender and straight legs, revealing a piece of crystal-clear, snow-white and pink calves, and a pair wearing white sandals with pink and jade-carved feet.

Li Tianzong had no relationship with Wang Xiyi. He always thought that Wang Xiyi was a girl very capable. Although she was working hard and wanted to get along with her classmates, she seemed to have something that made people feel inaccessible. Inadvertently, she gave people a feeling of being arrogant.

Li Tianzong knew that this was not because Wang Xiyi did this on purpose, but because she was born like this, or because her growth experience and living environment had developed her temperament. If she deliberately lowered her posture, she would still show it from time to time.

The pretty and simple girl beside Wang Xiyi had a ponytail, wearing a blue round-neck short-sleeved T-shirt and beige casual pants, which gave people a simple and pure feeling, which made Li Tianzong look at her twice.

This girl seems to be a classmate in the class. She looks pretty good and looks pretty. Although her skin is a little dark, she is very delicate and has a shy expression. She looks at Li Tianzong's big eyes full of curiosity, and she seems to be dodging and dare not look directly.

Li Tianzong smiled and nodded to the two girls, his voice a little hoarse: "Hello, are you okay with me?"

"Li Tianzong, your voice is not healed yet?" Wang Xiyi also nodded at him with a smile.

Wang Xiyi's smile looks very elegant, but gives people a sense of distance, which is far less cordial than the girl next to her big eyes.

Li Tianzong nodded and simply stopped talking.

Wang Xiyi didn't change anything. She walked to Li Tianzong with a smile and looked behind him: "You just went to the Internet cafe. Are you going to the classroom for class now? Let's go together?"

Li Tianzong nodded again. He was indeed going to class, not to mention that Wang Xiyi is also a beauty, and there is a little beauty next to her. The beauty invited her to accompany her, so it is naturally difficult to refuse.

In fact, Li Tianzong really doesn't want to walk with Wang Xiyi. Walking by the beauty will inevitably attract a lot of revenge and various gazes.

These eyes are admired and erotic to beauties, but most of the men around the beauties are jealous and hated.

It seems that now, Li Tianzong felt many less friendly eyes around him and bet on him.

Besides, he also thought that Wang Xiyi took the initiative to say hello to him and invited him to the classroom together, afraid that there was something to say.

Sure enough, when he walked out of the library, Wang Xiyi held up a small lilac umbrella, looked up at Li Tianzong, and smiled slightly: "Li Tianzong, you must take good care of your voice. Together with our class, if you want to participate in the competition in the hospital, you must be recognized by the classmates!"

"The squad leader wants to persuade me to quit?" Li Tianzong knew that his voice was hoarse and it was inconvenient to speak, but the beauty was talking next to him, and it was not good that he didn't say it, so he asked directly.

Wang Xiyi was slightly stunned, and two faint blush appeared on her fair and pink cheeks. Why did Li Tianzong say this? No wonder everyone calls him "Brother Zong"!
