When they heard Hou Xiaoqiang say this, Liang Jialiang and Sun Xiaoyong's faces suddenly looked ugly. They were not that they didn't believe Li Tianzong, but they just asked Hou Xiaoqiang to shout, but they had not turned around for a while.

Fan Xiaoxiao also smiled proudly and said, "Hehe, Li Changhao, I heard that you are a hacker, it's really amazing!"

"Hacker?" Li Tianzong raised his eyebrows, as if he realized something, but based on his understanding of hackers, it seemed that he specializes in attacking the network and personal computers. What does it have to do with mobile phones?

"Haha, if you can find Bluetooth, this phone must be on," Hou Xiaoqiang said smartly: "Fan Xiaoxiao, please call your mobile phone number quickly. When the phone rings, you will know where it is!"

Li Tianzong was slightly stunned, and then he realized that Li Changhao was using Bluetooth! He felt something was wrong. If Li Changhao and the others were not intimidating, that is, they could use Bluetooth to search for that Apple phone?

He originally thought that since Fan Xiaoxiao's phone could not be found, it must have undergone some change and completely disappeared.

Since there are more "Qianqian Jingting" and "qq" in his head, it is not impossible for a mobile phone to disappear completely. Even in his head, it is definitely not the original mobile phone.

So he was not afraid of Fan Xiaoxiao's perplexity.

Unexpectedly, Li Changhao actually searched Fan Xiaoxiao's phone with Bluetooth. What does that mean? It would never be a mobile phone of the same model, with the same name.

Could it be... Li Tianzong thought of a very bad possibility: the phone was in his head! And it could be searched by Bluetooth.

Li Tianzong had no time to consider the possibility of the phone in his head and the consequences it would cause. He was only worried that if he finally confirmed that the phone was on him and even if he stripped his whole body of clothes, would he have to be dissected?

Li Tianzong found that if he didn't handle this matter, there would probably be more and more trouble.

After hearing Sun Xiaoyong's words, Fan Xiaoxiao took out a new cell phone from her body and started dialing the original number.

When Li Tianzong heard Hou Xiaoqiang ask Fan Xiaoxiao to call, he was even more surprised. Generally speaking, if someone steals someone else's cell phone, he must turn off the phone and change the card.

Li Tianzong did not take the phone, but the phone was on him now. It can be found in Bluetooth, which proves that the phone is still on and he has not changed the card...

Li Tianzong stared at Fan Xiaoxiao's fast-moving fingers with a burning look, and he was extremely nervous. He didn't know if Fan Xiaoxiao could dial it. If it was dialed, what would happen.

Since Bluetooth can be found, the card has not been replaced... Li Tianzong is a little afraid to think about it anymore.

Fan Xiaoxiao pressed the dial button, lifted the phone to her ear, and quickly put it down: "It cannot be connected, I have called it many times."

"Wow!" Li Tianzong let out a long sigh. It turned out that it was a false alarm. He was worried that his phone could really be opened, and then... his mouth rings?

But thinking about it, it was impossible for Fan Xiaoxiao to have not called her number. She had not responded before, and now she was even more unlikely to respond. Li Tianzong shook his head secretly, feeling that he was still not calm enough.

"Haha," Li Changhao was looking at Li Tianzong all the time, and the smile on his face became stronger and stronger: "After so long, the mobile phone card has been replaced long ago."

"Then, there is always another way, right?" Hou Xiaoqiang scratched his head in disappointment, and wanted to show off in front of the beautiful woman, but there was no way.

"Yes, do you have any solutions?" Fan Xiaoxiao asked hurriedly, then glared at Li Tianzong fiercely: "You must leave this bastard without any escape."

Li Changhao looked at Li Tianzong and said confidently: "Since this phone is still there and Bluetooth is on, it can be searched, of course there is a way."

"Li Tianzong, what do you think?" Li Changhao asked suddenly.

Li Tianzong shook his head. This person was like a calm detective, bringing him a lot of pressure.

Li Tianzong even felt that if this continued, Li Changhao would really be able to reveal the secrets in him.

Hou Xiaoqiang, Fan Xiaoxiao, her support team, and even a few classmates watching nodded. Since they could find the Bluetooth signal, they should be able to find the phone through certain technical means.

Fan Xiaoxiao was very excited: "Li Changhao, look for it quickly."

Li Changhao smiled and retrieved the phone from Fan Xiaoxiao's hand: "I'm a copycat phone, which I assembled by myself. There is an enhanced version of Bluetooth on the phone. The effective search range is about 100 meters. Now, this ipne phone called Savage Princess has been searched on it."

"What can this mean?" Liang Jialiang couldn't help but retort: ​​"Your Bluetooth search range is as high as 100 meters. Even if you find this phone, it may not be in our dormitory."

Li Changhao smiled and said, "This really doesn't mean anything. I can only determine a rough range for us. Now that mobile phone is within a radius of one hundred meters."

"Isn't that all? One hundred meters!" Liang Jialiang curled his lips and said disdainfully.

Li Changhao had a smile on his face, not angry at all because of Liang Jialiang's robbery: "We can find a way to determine the specific location of the phone."

"For example, ask the public security organs to intervene and use reconnaissance equipment to determine the specific location of the signal source. However, our public security organs have a lot of things to do and may not make a big fuss for a mobile phone," Li Changhao said slowly.

Liang Jialiang curled his lips, and asked this guy to say anything he wanted to refute.

Li Changhao was always slow, as if talking to himself: "There is another way, which is to narrow the range. For example, use Bluetooth with an effective range of only one meter and search around. If the range can be narrowed to one meter, haha..."

Li Changhao did not continue to say it, but everyone understood what he was going to say. It is naturally not a problem to find a mobile phone within a radius of one meter; even if you can't find it, you can still see who is the suspect at a glance.

"Use mine, my old-fashioned mobile phone, the Bluetooth range is at most ten meters," Sun Xiaoyong immediately took out a black straight-board mobile phone from his body, turned on Bluetooth, and started searching for signals.

Fan Xiaoxiao stared at Li Tianzong with smugness, looking like she was hiding you. Sun Xiaoyong quickly raised his cell phone excitedly: "I found it, I found it, it's true that it's around here."

"It's obvious that the phone is within a radius of about ten meters, and it's still on," Li Changhao glanced at the phone in Sun Xiaoyong's hand and said slowly.

"Is there a mobile phone with a Bluetooth range of only one meter?" Fan Xiaoxiao glared at Li Tianzong. The range of ten meters is still too large, and it can cover at least a few dormitories around. If it can be reduced to one meter, I believe this rogue would have nothing to say.

Li Changhao shook his head: "Yes, but I don't. In fact, if you want to find the person who takes your phone, you don't have to use that kind of phone."

"What else?" Fan Xiaoxiao was so anxious that she felt that the boy in front of her was really slow, but he was really amazing. He almost left the thief with a few words. It seemed that he had asked him right.

Thinking that Li Tianzong would be unable to argue soon, Fan Xiaoxiao suddenly became a little excited.

"Application 1 is to let your suspect go to the football field, stand in the center of the court, and make sure that he is the only one within ten meters. Then you can determine whether the phone is on him," Li Changhao said with a smile.

"What if he didn't carry his phone with him?" Liang Jialiang couldn't help but question him when he saw Li Changhao's confident look.

"Don't forget, I'm a hacker, so there's another way..." Li Changhao smiled and raised the counterfeit phone in his hand: "This phone has a software installed on it that can perform some operations on other phones that turn on Bluetooth, such as checking mobile phone information, battery capacity, serial number, etc., and even making phone calls and playing music..."

"Damn, is it so powerful?" Liang Jialiang felt a little incredible: "Do you think you are 007!"

"It's not that magical. In fact, Bluetooth has such functions. For example, Bluetooth headsets can answer calls, make calls, and play music on your phone," Li Changhao smiled, his fingers jumped on the phone's keyboard, and called up the key sound. The phone suddenly ticked.

"So, controlling a mobile phone through Bluetooth is a feature that Bluetooth itself has, and it is not difficult."
