The "mysterious person" who wore a voice changer to talk to Feng Hao was Fang Ziyu, and contrary to Feng Hao's speculation, Fang Ziyu was on the roof of another residential building in the community from beginning to end, less than 200 meters away from him.

When the electric car siren sounded in the community, Feng Hao didn't hear the sound from the mobile phone, because Fang Ziyu would press the mute button every time he finished speaking.

Fang Ziyu's mind is not as smart as those geniuses, but he also has an advantage that others don't have, that is, he will never make the same mistake a second time.

The last time he returned the mobile phone to Wang Bing, the sudden ringing of the class bell made Fang Ziyu accidentally expose the fact that he was nearby during the call, although the mistake did not bring any adverse consequences, but Fang Ziyu also remembered it and was deeply impressed. Therefore, in the process of talking to Feng Hao this time, Fang Ziyu only turned off the mute state when he spoke, and every time he finished speaking, he would immediately press the mute button, so as not to expose his location in the ambient sound.

In fact, this trick is easy to crack, because after pressing the mute button, Feng Hao can't hear any sound in his mobile phone, not only the sound of talking, but also the sound of breathing, subtle environmental sounds, all of which will disappear, and those subtle environmental sounds will inevitably appear when Fang Ziyu speaks, as long as you pay careful attention, it is not difficult to find the difference.

However, Feng Hao was not so smart, and he had great ups and downs in his mood at that time, so he didn't notice this.

Fang Ziyu is not so bored that he teases the friends he just met, nor does he have a curious mentality and leisure to do social experiments, the reason why this is so is because Fang Ziyu needs a helper.

Several events happened one after another, which made Fang Ziyu realize that his situation may not be as safe as he had imagined, especially after seeing the news yesterday that Ouyang Jie, a Chinese-American high school student in Ohio, had stopped the school shooting, Fang Ziyu's sense of security decreased sharply.

Even if you are far away on the other side of the ocean, after seeing this news, you will immediately think that the other party may have a future notebook, so if there are other future notebook holders in the world, what will they think when they hear about what they have done?

Regardless of whether Ouyang Jie has a future notebook or not, he Fang Ziyu does have a future notebook!

If there really were other future notebook holders, and Fang Ziyu had caught their attention and attracted their temptation, what would be the consequences? I can't imagine.

Although Fang Ziyu has not found any strong evidence so far, which can prove that there are other future notebook holders in the world, but be careful to sail the ship of ten thousand years, especially before he is strong enough, no matter how cautious he is, after all, this is a major matter related to his family's life.

So Fang Ziyu needs a helper, or rather, a puppet who walks to the front of the stage instead of him.

If the future tablet always releases some future clips that foreshadow tragedies and tragedies, Fang Ziyu can't always go into battle in person, if he goes in person every time, he will inevitably leave clues, and sooner or later he will be noticed. Besides, Fang Ziyu didn't want to be a firefighter forever, so he thought that he could let others change the future.

Judging from the experience of previous tasks, the real difficulty in changing the future is actually to obtain information, as long as you can obtain enough information, and then reverse the fragment of the future you see, maybe a phone call can erase the disaster from the source. Therefore, what Fang Ziyu really has to do is to hide behind the scenes and gain insight into the essence of the incident, as for the hands-on and errand work, it can be completely outsourced.

But outsourcing also has to pay attention to skills, and you can't just pull someone to let him change the future. Because everyone in the real world has thoughts, not NPCs that can be controlled at will, once the people who find them start to be curious and start to explore why the instigators behind the scenes can always accurately predict the future, it will be a fire.

Fang Ziyu couldn't control other people's curiosity, but at least he could hide himself, so after careful consideration, Fang Ziyu chose to "recruit" Feng Hao in this way.

Feng Hao is the most suitable person Fang Ziyu can find now, he doesn't have overly complicated minds, his mind is not too smart and he is not stupid, he is not easy to do bad things, and he is not smart enough to guess Fang Ziyu's secret after a few interactions. What's more, Feng Hao is alone, with only one friend, Xu Baiyi, even if he can't help but reveal the secret, he has no one to confide in. Moreover, when he really encountered a critical situation, Feng Hao had nothing to worry about.

For what he did and thought, Fang Ziyu did not feel glorious, he did become smarter, but at the same time, he also became "bad".

Fang Ziyu, who was sincere to people in the past, would never treat his friend as his pawn, even if this friend had only known each other for less than a week.

Maybe it was because he remembered his previous self and couldn't let go, so Fang Ziyu gave Feng Hao three chances to refuse, if there was danger in carrying out the task, Feng Hao could refuse, if Feng Hao refused, then Fang Ziyu would find someone else, or end up in person.

"If someone knows what I've done, they may scold me for being a cousin and wanting to set up a memorial arch." Fang Ziyu said something to himself, leaned on the railing of the rooftop and looked up at the sky, and began to recall whether there was a flaw in his arrangement.

Considering that the instructions given later may be very strange in Feng Hao's opinion, Fang Ziyu gave inexplicable instructions from the beginning, such as running up to the rooftop and turning over bricks, such as taking off his shirt and wrapping it around his arm, and letting Feng Hao do these things don't have much meaning in themselves, only two purposes.

The first is to let Feng Hao get used to this kind of inexplicable instructions, get used to following instructions, and form the concept of "you can get cash rewards by following the instructions on the phone" in his heart.

The second was to divert Feng Hao's attention and let him not explore the coat hanging on the tree too much.

The coat given to Feng Hao, the fabric and workmanship are very good, after Fang Ziyu bought the coat according to Feng Hao's size, he did some tricks on the coat in a tailor's shop in the old city, he asked the tailor to cut a small hole on the inside of the coat, stuffed a tracking chip into it, and then sewed the coat, so that as long as Feng Hao wore this coat, Fang Ziyu could know his location through his mobile phone or computer at any time.

In fact, Fang Ziyu's card mobile phone at Feng Hao's door also has a positioning function, that kind of card mobile phone was originally designed for the elderly and children to use, after binding the number used by the card mobile phone to the "guardian number", use the guardian number to send a text message to the designated recipient, you can receive a reply within one minute, and know the location of the card mobile phone.

But just having a positioning tool is not enough, in order to take another layer of insurance, Fang Ziyu customized the coat for Feng Hao, relying on the tracking chip, not only can locate the location of the jacket at any time, but also remotely turn on the recording and monitoring functions, and complete the positioning function of the card mobile phone, the only drawback is: Feng Hao will charge the card mobile phone, but will not charge the tracking chip.

However, it is not difficult to solve this problem, after the tracking chip runs out of power, let Feng Hao throw away this dress and change it or send another one, as for whether it will arouse Feng Hao's suspicion at that time, if it arouses suspicion, how to solve it, Fang Ziyu has not thought about it for the time being.

We'll talk about it later, so let's get the matter in front of us first!

Fang Ziyu took a deep breath, picked up his handbag and walked downstairs.

Next stop, No. 6 Middle School.
