After hurriedly washing up, Li Zhengyi hurried to the Internet café in a hurry.

As soon as he entered the Internet café, Li Zhengyi couldn't help but be stupid, didn't he say that there was something wrong with the legend? Why are the people in the Internet café still having a lot of fun, and the legendary game is very normal.

Li Zhengyi was about to ask what was going on, but Shao Qin said in the bar, "Come in quickly." ”

"What's wrong?"

"Come and see. Shao Qin said to Li Zhengyi, who walked into the bar, "I was tying gold bars, and I found that the money in the backpack would not decrease no matter how I bundled it, but the gold bars increased one by one, do you think there is a problem?"

Li Zheng opened Shao Qin's little warrior's backpack hanging in the safety zone at one point, his eyes were staring at him, and his mouth was wide open and he couldn't close it at all. In the backpack of this little soldier named Zhengyi Internet Café, Huang Cancan's bag of gold bars.

"You...... How did you get here?" Li Zhengyi's voice trembled a little.

"In exchange. Shao Qin didn't understand what was going on, and told her about how Li Zhengyi taught her how to tie gold bars yesterday.

Li Zhengyi said: "I remember that you little soldier didn't have gold coins, where did the gold coins come from?"

"I asked Li Yong for it. Shao Qin said, "I came to clean up in the morning, and it happened to be empty, so I got on the Little Warrior and wanted to try to tie the gold bars again, and then found that the Little Soldier didn't have enough money, so I asked Li Yong to trade it for me." ”

Looking at the 1,002,000 gold coins in the little soldier's backpack, Li Zheng's scalp suddenly felt a little numb, he knew that his little aunt had inadvertently hit the right and touched a crazy money swiping bug in his previous life.

I heard this loophole in my previous life, and at that time, Li Zhengyi heard these things in a fog, and he always went in and out of his left ear, so he didn't know what the loophole was about.

Li Zhengyi calmed down his mood, and then said, "Little aunt, this matter is a bit big, are you silent?"

Shao Qin said no.

Li Zhengyi said again: "That's good, you tell me the original story." ”

The two hid behind the bar and whispered, and after a while, Li Zhengyi figured out the ins and outs clearly, and sighed in his heart after listening to it.

Things have to start with Shao Qin.

In the morning, Shao Qin finished cleaning and boarded the Little Warrior, and wanted to go outside Beechcraft to play with the scarecrow, but suddenly thought of Li Zheng's bundle of gold bars yesterday, and also wanted to use this number to try, so he ran to the warehouse for a bundle in a hurry, but was prompted that the gold coins were insufficient.

Shao Qin knew that Li Yong controlled the miner's number, so he chatted with Li Yong privately and asked him to trade some gold coins for himself.

Li Yong happened to sell ore in Viper Village, dug for a night, plus the rest before the update, less than one million, so he asked Shao Qin how many gold coins he wanted.

Shao Qin is more serious in his work, and he usually keeps accounts and calculates accounts at a glance, and he is not sloppy at all. So Li Yong asked her how many gold coins she wanted, and she pulled the calculator commonly used at the bar, used the one million plus the handling fee that Li Zhengyi said, subtracted the gold coins in her backpack, and then told Li Yong the amount of gold coins she needed.

Li Yong is a person who is more rigid in doing things a lot of times, he saw Shao Qin give a specific number, and he didn't ask why, he honestly traded gold coins according to the number provided by Shao Qin.

In this way, the gold coins in Shao Qin's backpack are fixed at 1002000, a Shao Qin who does things with a single glance, and when he encounters the hard-brained Li Yong, he accidentally opened the most bizarre BUG of the legend.

Luck can't be stopped, Li Zhengyi can only sigh like this, if he had known that this bug appeared so early, and he could still be discovered by his aunt, why did he waste so much time, running to change construction drawings, ask gangsters, buy computers, buy tables and chairs, pull broadband, and be busy for so long, in fact, he can't afford a single BUG.

This bug, Li Zhengyi heard of it in his previous life, but he never asked how to get it, and he didn't know how to operate it, and the only time he remembered the outbreak should be after the opening of the White Sun Gate.

In his previous life, before Li Zhengyi went abroad to mix in society, he fooled around in the coastal area all day long, and he played private clothes when he had nothing to do. It is said that it was after the update of the White Sun Gate that this bug broke out, causing the legendary gold coins to instantly depreciate to nothing.

Compared with other more complex money and equipment bugs, the gold bar bug is not very difficult to understand. However, Li Zhengyi's temperament is relatively lazy, and he will never study these outdated things, nor will he spend his brain to understand those useless things, so in this life, Li Zhengyi only knows the approximate time of the outbreak of legendary bugs, and he doesn't know how to operate specific bugs.

The gold bar bug actually uses the basic principle that the gold coins in the backpack cannot be 0 to make logical errors when processing the program, and the program design does not take this into account, and at the same time, there is no logical error rollback mechanism. Therefore, once this error occurs, the server program will return the same amount of gold coins to the player's backpack at the same time as the gold bar, and the program believes that both parties are legitimate, thus forming a loophole for swiping gold bars.

This loophole is not very difficult, but it was hidden in the legend for more than a year and no one knew about it, and then someone inadvertently, just like Shao Qin today, was discovered by mistake.

The difficulty lies in the fact that it is difficult to coincidentally reach the value of 1,002,000 gold in the player's backpack. Once this value is reached, when the player is bundling gold bars, the legendary client runner will first send a request to the server for gold bars, and the server will determine whether the number of gold coins in the player's backpack can complete the verification requirements for gold bars.

This verification requirement is the amount and handling fee of the gold bar itself, and the total value is 1000000+2000, so below this value, the gold bar binding instruction cannot pass the verification.

After the server is verified, it will send an instruction to the server to execute the program, adding a gold bar to the player's backpack and deducting 1,002,000 gold coins from the player's backpack.

At this time, a logical error is formed, when the server executes the program to give gold bars, it is because the player's backpack does have the equivalent amount of gold coins, and this instruction is reasonable and legal through the verification procedure, so the execution program cannot be reversed. After the server executor deducts the 1,002,000 gold coins in the player's database backpack, it is found that the player's backpack gold value is 0, and the backpack gold value is 0, which is expressly forbidden in the basic principles of the main program.

What to do?

Quite simply, the server executor thinks that this deduction of gold is wrong and cannot be executed, so the same amount of gold must be returned.

Of course, for Li Zhengyi, these principles are equivalent to playing the piano to the cow, and he doesn't need to understand these, as long as he knows that now that he has mastered a super money BUG, then countless servers and all gold coins can be monopolized.

How much of an asset is that?

The wealth is actually not much, Li Zhengyi is not a fool, at this stage, the legend has three district servers, and the current number of players is more than 10,000. Although gold coins are in short supply, there is a limit to the amount of consumption that players can spend, and they will not be sold if they are sold to a certain extent.

If Li Zhengyi stupidly dumps gold coins in large quantities, it is not certain whether he will be investigated, the key is that if there are too many gold coins, it will cause instability in the gold coin market.

Therefore, the biggest advantage of this BUG is that it saves Li Zhengyi a lot of time and manpower and material resources, and the gold coins that originally needed to be accumulated by time now only need to click a little mouse.
