Qin Feng returned to his RV again after being away for more than a month.

If this house had been unoccupied for more than a month and the doors and windows were tightly closed, it would definitely be filled with a musty smell.

Why does a house have a musty smell if it has been unoccupied for a long time? This is because the bacteria that breed in a humid environment without ventilation for a long time will produce a putrid smell. In a closed environment, furniture, leather goods, wood products, etc. slowly release

The odor cannot be dissipated and gradually accumulates to a certain concentration.

These gases are naturally harmful to the human body.

This kind of thing usually just needs ventilation.

Of course, fungi in the air will persist for a long time.

it's actually really easy.

Take out a little mugwort and put it in a bowl, then drop a bottle of 82-year-old Fengyou essence on the mugwort, then light it, and finally place it in the room. After it burns out, wait for the smell to dissipate, and leave the room

The musty smell will disappear. Fungi in the air will naturally be killed.

Qin Feng was also worried that there would be a strong musty smell in the RV, so he prepared mugwort and Fengyoujing in advance.

Unexpectedly, after opening it, there was no musty smell inside.

After calling to inquire, I learned that this RV has an automatic ventilation function that will continuously keep the air in the RV fresh. Moreover, if the air is too humid, it will also turn on dehumidification. Moreover, it will automatically turn on when no one is inhabiting it.

Use ultraviolet light to sterilize and ensure that everything in the car is in a clean state.

Of course, these all require electricity.

However, the entire vehicle management system of the RV has already been set up by itself.

If there is no external power supply, the RV will automatically reduce the air freshening time and dehumidification times. As for the ultraviolet lamp, the turning on time will also be reduced. Moreover, when the energy is about to be insufficient, in order to ensure that the RV can start, it will be turned off

All power-consuming equipment.

And if the external power supply is turned on, it will automatically follow the normal procedure.

As for Qin Feng, he connected charging piles and water pipes from Harvard to ensure the water supply and power supply of the RV.

After all, no matter how big the battery is, you can't really use it as you wish.

Therefore, the entire RV maintains a very pleasant air environment.

This made Qin Feng very satisfied.

Afterwards, Qin Feng checked the security issues in the RV to see if anyone had entered. After confirming that there was no problem, Qin Feng turned on his computer and logged into the dark web.

Qin Feng has not logged in for more than a month.

Although it is said that logging in in China is actually possible.

Moreover, Qin Feng believes that the safety factor should be very high.

After all, China is very vague about the dark web and not too clear about it.

However, for safety reasons, Qin Feng still did not log in.

Be sure to log in in the most secure environment.

And this RV is the safest login environment Qin Feng has found so far.

The entire RV is bulletproof, including rockets, which can withstand one shot. Moreover, if the enemy wants to release poisonous gas, the RV will call the police.

In this way, whether it is a forced attack or a covert attack, Qin Feng has enough time to destroy the evidence so that no one can obtain any data from his computer.

After all, Qin Feng also studied IT, and he is also the chairman of the Baike Alliance.

This is no joke.

Qin Feng knows very well how to delete hard drive data without being retrieved.

Simply delete it and you can get it back immediately.

And if you overwrite it repeatedly, you may not be able to cover all the data.

Therefore, under normal circumstances, if the FBI attacks, in the movie, hackers can delete all the data in the computer with one click of a button and cannot get it back. That is really a joke.

Indeed, the FBI is afraid that hackers will delete all evidence, so it generally will not act rashly and will conduct raids to prevent it from being deleted.

However, that’s because hackers are afraid of taking precautions and deleting it in advance. If you give hackers time to prepare, once the data is deleted, it cannot be retrieved.

But if you rush in directly, the hacker will be caught off guard. Even if he can delete some data, he can still intercept a large amount of data.

After all, it takes time to overwrite data on the hard drive.

The larger the hard drive, the longer the overwriting speed.

Therefore, Qin Feng has specially developed a small program.

Once someone breaks into the RV, Qin Feng will start this small program.

This small program will use the fastest speed to quickly copy and post data in the same sector of the hard disk, filling the entire hard disk. Because it is the same sector, copying and posting is very fast.

After the hard disk is full, it will start to destroy sectors, and then clear the sector data. Then, re-create sectors, reconstruct the simplest data, quickly copy and post, and then delete it again.

It will continue until it is forcibly terminated.

In this case, Qin Feng had timed it to 7 minutes. As long as he gave himself 7 minutes, he could modify the entire hard disk and no longer be able to retrieve any data.

Of course, 7 minutes is too long.

If it takes 5 minutes, it can be guaranteed that 95% of the data will be overwritten and difficult to retrieve.

If it takes 3 minutes, 70% of the data can be covered.

If it's only 1 minute, it can only cover 30% of the data.

Of course, the reason why this small program designed by Qin Feng is so powerful is that it can prioritize coverage based on core data sectors.

In this way, even if it only takes 1 minute, 30% of the core data can be covered.

Basically, it would be extremely difficult to retrieve it, especially to find useful information against Qin Feng.

After logging into the dark web, things changed a lot.

The content of the external network of the dark web is even more complex.

Naturally, since it is a dark web, all illegal activities are published on the outside.

Qin Feng used his privileges to check and found that the transaction rate was very high.

Basically, the closing rate is over 70%. This is already very high.

This will lead to the darknet being sought after by more illegal people in the future.

As for illegal activities, Qin Feng briefly scanned them and stopped looking.

Because many of them are anti-human, very perverted, and even cruel.

Qin Feng is worried that if he watches too much, he will become mentally ill.

This person is the most vulnerable.

It is easy to learn bad things but hard to learn well.

If you stay in a place like this for a long time, you may become mentally twisted.

Once it's distorted, it's ruined.

Therefore, Qin Feng directly entered the darknet network.

Compared with the external network, this place is simply a paradise on earth.

Basically there are no changes. Most of the forums are discussing various technologies.

They are all in harmony with each other. It is not like the bloody storm on the outside network.

Everyone also expressed respectful greetings to Qin Feng's arrival.

After all, the existence of the darknet is all because of Qin Feng. Everyone respects Qin Feng, the founder.

Because their lives have changed for the better.
