I am the only one who practices magic: I practice magic in the city

Chapter 142: The Invasion of the Arcane Trojan Horse (First Update)
"Yeah, it's okay. I've already dealt with it. I'll be back soon. I've already entered the community. Qiqi, you go to sleep first. Okay."

Fang Yu parked the car and Tang Yufei just hung up the phone.

Fang Yu picked up the phone and saw an Alipay transfer message.

Twenty thousand yuan was exactly the amount of money he had just paid as a deposit for the hospitalization of Fan Bingcheng and his wife.

Transferor: tangtang390521.

"After the exam, I will send them back to Haipu. Their medical insurance is there, and they have a lot of assets there, which should be enough for their medical treatment." Tang Yufei drooped her eyelids and said in a low voice.

Fang Yu glanced at Tang Yufei and said calmly: "Go back and rest early."

Tang Yufei hummed and forced a smile.

Along the way, Tang Yufei was very silent.

Maybe, I really have a bad fate.

Anyone who has a close relationship with me may end up being unhappy.

The real world is not a novel, and it is difficult for parent-child relationships to be truly satisfying.

Although Tang's mother and Fan Bingcheng were locked up in a mental hospital, Tang Yufei seemed to have escaped from the imminent danger and seemed relieved.

But from Tang Yufei's perspective, this also means that life in the future may become more difficult.

She is Tang's mother's biological daughter and Fan Bingcheng's stepchild. Legally speaking, she is obligated to support these two people until her death.

Both the biological mother and stepfather are mentally ill. This family situation is an unbearable burden for any ordinary person.

Fang Yu watched Tang Yufei enter Unit 2 of Building 2, then picked up Youzi and walked towards Building 3.

"Master, I found a problem." Yuzi said softly, the yellow light on his body flickering.

"Every time this woman comes to 601, you lock me in the car. Why is that?"

"Even if I'm at home, I won't say or move around. You don't have to worry about me being exposed."

Fang Yu rolled his eyes. Are you afraid that you will say or do something wrong?
That’s because I’m afraid you’ll look around!

"Okay, now let's try the Arcane Trojan." Back in Room 601, Fang Yu was ready to go, and Yuzi also glowed orange with excitement.

This Trojan was compiled by Youzi during Fang Yu's group meeting in the afternoon. It took nearly an hour, which was longer than the time it took to invade the Magic Network Wave Monitoring System.

After all, the magic network fluctuation monitoring system is still within the application scope of arcane, and this time Yuzu wants to hack into the computer, which has nothing to do with arcane.

Based on the last experience of using the "reading technique" on the computer, it may be due to the problem of the computer's overall data bandwidth. The computer cannot accommodate too much arcane information in a short period of time.

Therefore, youzu needs to further reduce the size of the Arcane Trojan to a level that the computer can bear.

But according to Youzi's calculations, no matter how it is compressed, the amount of information in the Arcane Trojan will still exceed the bandwidth limit that the current north bridge chip and BIOS can withstand.

Just when the idea of ​​one person, one ball had reached a bottleneck, the huge fan noise emitted by Cheng Feng's old computer, which had been used for more than three years, at the group meeting gave Fang Yu an inspiration.

Can a Trojan be attached to a power supply?
Using the power supply as a carrier, the Arcane Trojan enters the power management chip of the motherboard along with the electric current, and then invades the core system of the computer through the power management chip?
Youzi had never thought of this plan, so he modified the Arcane Trojan according to Fang Yu's idea.

Just do it.

Fang Yu first took out his M17X from three years ago. Although it was a 3058 machine, the combination of i7-3820QM+GTX 680M still has decent performance today.

I'm sorry, old friend. If you were damaged by the arcane Trojan, I would definitely use repair technology to fix you as soon as possible. From childhood to adulthood, Fang Yu kept every computer he had used and never sold it.

In his room at home, there is a special shelf for storing electronic products he has used.

Yuzi's arcane Trojan this time was divided into two steps. The first step was to let Fang Yu cast a self-created first-level spell - blessing - on the laptop power supply.

This spell is actually a first-level spell of light, which was a scroll of magic that he bought from Master Jacques when he first went to the main plane.

After Yuzu decompiled the magic scroll, Fang Yu obtained the algorithm of the spell, and recombined his own parameters to generate a corresponding spell model in the sea of ​​consciousness.

The blessing spell is effective for 3 minutes and its function is to increase a person's luck when doing something.

For example, when you buy a lottery ticket, when you buy the Double Color Ball, you draw 33 balls from 6 balls. When you draw the first ball, the probability of drawing the first red ball you choose is 1/33.

Suppose you cast a blessing, which may increase your luck by about 40% when drawing the ball, that is, 1/33*1.4, then the probability of drawing the ball you choose becomes 1/24.

The same goes for the second red ball.

Fang Yu used the blessing spell on the power supply at this time not to increase the success rate of the Arcane Trojan's invasion, but to use the blessing spell to serve as an interface for the Arcane Trojan.

To function as an interface, the spell must be a continuous enchantment school spell.

The so-called continuous spell does not mean that the effect is continuous, but that the spell is continuously attached.

For example, the sleeping spell can make a person sleep for at least ten minutes, but these ten minutes are the effect time after casting the spell. The spell does not stay attached to the recipient for ten minutes. After hitting the target, the spell has taken effect and disappears.

Among all the spells that Fang Yu currently masters, the only two that are truly continuous spells are Arcane Armor and Blessing.

The Mage Armor will increase the difficulty of invasion by the Arcane Trojan and obviously cannot be used as an interface.

After casting the blessing, turn on the machine.

At the same time, the grapefruit had turned silver-white, and the arcane Trojan was injected into the blessing magic that was already attached to the power supply. Along with the current in the power supply, it invaded the power management chip next to the CPU.

The computer's boot process remains the same as usual, without any impact.

"It works!" Fang Yu and Youzi were both excited.

This method really works!
The power management chip has built-in multiple protection mechanisms.
Yuzu carefully controlled the Arcane Trojan to simulate normal voltage fluctuations to prevent the voltage fluctuation protection from taking effect.

Then, it controls the current waveform to avoid the overcurrent protection mechanism and adjusts the frequency and intensity of the current to prevent the overtemperature from triggering the overheating protection.

After cracking the hardware protection, the Arcane Trojan begins to analyze and crack the protection algorithm in the power management chip firmware.

The protection algorithm in the power management chip is not complicated. In a blink of an eye, the Arcane Trojan successfully bypassed the firmware protection and access control and successfully gained control of the chip.

After occupying the power management chip bridgehead, the Arcane Trojan quickly replicated and soon embedded itself into various chip systems and operating systems of the computer.

At this point, the mission of the Arcane Trojan has been successfully completed.

Fang Yu first used the antivirus software that came with Windows to check and found nothing.

Success! Fang Yu waved his fist vigorously.

No, it's too early to be happy, it's only half successful.

Now, it depends on whether Yuzu can transfer part of his consciousness into the computer through the Trojan horse as an anchor!
