The second round of questions is multiple-choice, and one or more answers are selected from ten options, all right, and the next round is progressed to the next round, false, eliminated, and it must be fast.

Yuxing knew through telecommunications spiritual power that the entire exam server group still had some unsavory functions.

For example, timing, recording the time for each player to answer questions of all levels of difficulty, the same F-level question, you took 30 seconds to answer correctly, but he only had 25 seconds, which reflects the gap between the players and the players. Of course, the difference of a few seconds and more than ten seconds for a question like a multiple-choice question is not obvious, after all, the number of text descriptions for each question is different. But later, when programming problems arise, this kind of reference will be valuable.

Another example is the "less time to increase the difficulty of the question" function, this function is different from the obvious rules stipulated in the number of people decreased, the difficulty of the question increases accordingly, it is only an implicit function for individual players, simply put, the shorter the time for the previous round of answers, the difficulty of the next round of questions will increase invisibly, anyway, there is a "decrease in the number of people and an increase in the difficulty of the question" in the way, and the players in it cannot feel the changes. And the real performance of each candidate has long been truthfully recorded in the database of the exam server group, and it has been clearly grasped by the rice guys.

Therefore, Yuxing monitored the entire examination system with telecommunications spiritual power, and answered the questions at the same time, ensuring that his position in the next round fluctuated around one hundred, neither outstanding nor lagging behind. There are still a lot of tasks to come to the United States this time, although he is the one who is placed on the surface to attract firepower, but there is no need to be a bird. Just get a decent grade and enough to make a difference. Of course, if the comprehensive results of these people in the domestic participating group really enter the top three, he doesn't mind giving a boost and bringing the collective honor back to China.

In a word, Yuxing's plan is not to drag the participating teams back, and he doesn't mind being the champion when the participating teams are competing.

However, judging from the information fed back by the telecommunication psychic power. The possibility of the domestic team winning the championship is very small, because it has just entered the third round, and only about 50 people are left in the more than 90 participating groups.

The questions of the third round began to become conscious. It's a programming problem, and almost all of the contestants who made it to the third round get the same questions, and the text descriptions seem to be varied. In fact, after a detailed analysis, the needs and purposes of programming are the same, that is, to make a scanner, as for scanning the information transmission port or scanning the system vulnerability, the contestant himself will do it.

"Mother Fakyu!" Yu Xingwo scolded in front of the computer screen, "Isn't this a mistake?" And it was so blatant. ”

To put it bluntly, a scanner is a beginner hacking tool, and it is also the most basic hacking tool. To put it simply, it's as if a thief has entered a residential building, and his purpose is to steal, and it doesn't matter which one he steals. The key is to be able to enter the house, but he looked upstairs and downstairs, hehe, and found that there was a door that was not closed tightly, and it was hidden. And there's no one, so it's not easy to catch! The process of checking upstairs and downstairs is called his scan!

Generally, hackers who don't get into the stream use scanners made up by others, and when someone can independently write their own scanners, then he is already an entry-level hacker. Although this level of hacking is not a big threat, it still has technical skills. It can be called a talent, and as long as it is a talent, the Immigration Bureau of the United States is willing to accept it!

What the? What did you say? It is possible to infiltrate spies from other countries. It doesn't matter to the USCIS folks, what matters is that the annual tax dollars that Congress spends on the intelligence and counterintelligence services are not in vain, and these units have something to do.

Yuxing thought about it, but reluctantly wrote a scanner. However, the scanner function he made up was satisfied, but the code was too redundant, and the functions that others could achieve with two lines of code, he wrote three or four lines or even five lines. …,

Such a scanner is naturally not very fast to use, but what is time for a hacker? That's fate! Find the door quickly, open the door quickly, turn over the cabinet and steal things quickly, and sweep the tail and exit quickly. In a word, a fast hacker is not necessarily a top-notch hacker, but a top-notch hacker must be fast, and it is all-round fast, and it is fast-paced.

It was precisely because Yuxing had compiled a "bloated" scanner that he had fallen outside the top 300 when he entered the fourth round, and even so, he was in the first group among thousands of players, not to mention the more than 1,000 unlucky guys who had been eliminated at this time.

Sure enough, the question of the fourth round was as Yuxing expected, giving an IP address, allowing the contestants to find a way to enter the server with this IP and create an account with their own entry number as their username.

If the previous round of writing scanners was a normal selection, the requirements for the fourth round of questions are already a living invasion. It's just that the IP addresses mentioned in the title are all in the IP segments of Harvard and Massachusetts, and Yuxing checked it with telecommunications spiritual power, and there are only more than 30 IP addresses assigned to the remaining 3,000 players.

The most important thing is that each server has a number of permissions to create accounts, and a single server can only create fifteen accounts, which means that if you want to enter the next round of the competition, you need to kill at least 100 people.

It is conceivable that at that time, there will be N people scanning on each server, and N people are competing for permission to try to create an account, and how lively it will be is absolutely impossible to describe in words.

And the guy who can kill from the many players pulling each other's hind legs, no matter how high the strength is, the players themselves will be convinced without saying anything from the organizer. Besides, when trying to enter (invade) these servers, it doesn't mean that you are safe, so many players, there are not a few who don't like each other, and it is not impossible to follow the data flow of the other party's test server, hack the opponent's exam computer, and completely kick the other party out.

I thought that this kind of behavior was already illegal, and the players from all over the world would have some scruples, but the players were mostly excited. Is there anything more exciting in the world than to be able to invade blatantly?

The answer is no.

Therefore, at the beginning of the fourth round, each player had a look of fascination on their faces, as if they were in a state of addiction after playing CS for the first time, and some even shouted in the arena.

Indeed, the fourth round of the match was just a matter of using one's own computer skills to kill each opponent instead of using firearms.

Yuxing's telecommunications spiritual power also discovered an interesting thing. In the fourth round, it was not without the withdrawal of competitors, and the entry numbers of those who withdrew were recorded separately in a separate database.

I have to say that active withdrawal is not necessarily a good thing, because there are only two possibilities for active withdrawal, one, the ability to easily create a server account, and second, there is no technology in this area. But you can even make up a scanner, dare you say that the slightest bit of technology won't hack into the server? No one believed it, and it became logical to keep the numbers of these people separately.

There is a total time limit for the entire fourth round of the competition, and the fifteen players who have the authority of the server account will automatically enter the next round when the specified time is up, and there are more than 30 servers, which is just over 500 people.

However, the players used the teaching computers provided by the two famous universities, and did not have the right tools at hand, a few downloaded some technical tools from their online mailboxes, and many more wrote some simple tools to help hack into the server.

So, the battle for server account slots has been boiling out from the start. Yuxing could only imagine how fierce the battle was when he saw the number of eliminated people in the upper left corner of his computer screen rising. …,

Yuxing has telecommunication spiritual power, and he didn't mess around at the first time, he was like a god on top, silently watching all the actions of the players who were assigned to the same IP server as him, and quickly found a few outstanding guys.

These guys were the first to create an account in the server and successfully withstand other people's attacks. Not only that, but from time to time, they also betrayed other players who had created accounts, and together with external attacks, they canceled these newly created accounts, freeing up the pit for others to drill into, so that the pressure on several of them was naturally greatly reduced.

Yuxing checked, without exception, these lewd guys are all little devils, and there are more Noda and Goto among them.

As for the guy who has been in the hands of a long time, Yuxing estimates that the chicken feet are not crazy yet! What he has to do now is to wait for the moment when the whole time is about to come, and hack all the game computers of these little devils, and then they will not even have the tools to commit the "crime", and they will make a fart! But before that, Yuxing first had to make sure that his game computer didn't go wrong.

Because Yuxing has been hiding from the side to watch the excitement, he has only scanned the available ports of the server, and has never launched a real invasion of it, so there are no players who come to him. On the contrary, the computers of the players in front of and behind him would crash or restart from time to time.

Suddenly, one of the contestants in the front row jumped up and shouted, "Wow, it's smoking!" ”

But no, there was a trace of white smoke in the cracks of the chassis on the table, and Yuxing even heard the "snort" sound of the hard disk inside spinning too fast.

It seems that this player is very guilty, maybe he offended some villain, and even hacked him into the computer with a hardware destruction virus.

The Massachusetts professor who was invigilating on the spot turned blue and called the player with the smoking chassis out of the competition venue. But why does Yuxing think that the old professor's eyes are full of banter?

In full swing of telecommunications spirit, Yuxing soon found out that Harvard and Massachusetts had ordered a batch of new computers more than half a month ago, and the current competition computers were old goods from several years ago.

Yuxing instantly understood what the idea of this group of foreign grandsons was fighting. Sure enough, before his thoughts could be finished, there were twenty or thirty more players coming out of the chassis of green smoke. (To be continued.)
