How to break into a math book

The man was obviously much calmer than the bartender. Hearing Tu Hua's inquiry about the password, he put away the poker cards on the table, raised his eyebrows and said with a smile, "Holmes sent you?"

Tu Hua didn't know what kind of relationship this person had with Sherlock Holmes in the plot, so he didn't dare to answer rashly.

The man spread out the cards in his hand again: "Don't be nervous, Mr. Holmes and I are old friends. If there is any news he wants, I will know everything."

Tu Hua smiled: "Whether we have anything to do with Mr. Holmes or not, you should be clear that we are definitely not doing bad things."

The man glanced at Tu Hua in surprise, did not continue the topic, pointed to a few poker cards in front of him and said, "If you want to investigate a case, you must have the ability to investigate a case. Let me test you first. I have five cards in front of me." Playing cards, in order from left to right are A, 2, 3, 4, 5, move only three times, and change the order of these five cards according to the method of transposition of the four adjacent cards. 5, 4, 3, 2, A, I will tell you the information of the lockbox."

Tu Hua looked down at the five playing cards, which meant that the order of the five cards should be completely reversed according to the two-by-two exchange method, and they could only be moved three times at most.

Compared with the levels they had experienced before, this little poker trick was simply too simple.

Tu Hua quickly thought of the answer without the need for two military divisions to come up with advice.

从A、2、3、4、5变成5、4、3、2、A,对于第一张牌A来说,从第一个位置移动到最后一个位置，所以必须要将A尽可能的后移。而移动方法只有相邻的四张牌两两换位，所以想要把A换到后面位置，只能把A、2和3、4先进行互换。

于是涂化将3、4两张牌换到了最前面，五张牌的顺序变成了3、4、A、2、5。

The second change of cards is still marked by A. The current position of A is in the middle. If you want to adjust A to the last one, you can only exchange 4, A and 2, 5, so in the second change of cards After that, the order of the five cards becomes 3, 2, 5, 4, A.

最后的结果就显而易见了，只需要将5、4和3、2调换位置，牌的顺序正好可以在第三次换牌之后变成5、4、3、2、A。

"Very good." The western cowboy nodded in satisfaction, and did not embarrass them any more, and said the information of the lockbox, "Tom only told me 'O is neither the first nor the last', and you need to find someone else for other information." OK."

Tu Hua quickly wrote down this message.

According to the bartender, the five-digit code needs judgment information from five people before it can be reasoned. If this routine is followed, besides the western cowboy, the other four people should also pose some problems for them.

Tu Hua thanked the man, and walked towards the second person who knew the password information.

This is a young blond man, sitting alone by the window drinking, looking out of the window in a daze.

Tu Hua walked up and patted him on the shoulder carefully: "Excuse me, may I ask..."

Halfway through the speech, the young man turned around, and Tu Hua was so shocked that he couldn't speak.

This man looks really beautiful.His eyes are clear blue, as crystal clear as sapphires. He has a high nose bridge and deep facial features of a Westerner, but they look soft when combined. When he looks at others, there is always something in his eyes. The attractiveness of pulse makes people unable to take their eyes off at all.

Not only Tu Hua, but also Sun Wei and Shen Siyi behind him were stunned.

The young man smiled: "What's the matter with you?"

Only then did Tu Hua come back to his senses, and stammered: "Well...we want to find out about the password that Tom said last night."

"Oh, so this is the matter, please sit down first." The young man pulled away the chair beside him, let Tu Hua sit down, and said with a light smile, "You stay with me for a while, and I'll tell you."

There are only two chairs in this window seat, and they are very close to each other. If you sit down, it is equivalent to leaning directly in his arms.Tu Hua struggled for a long time, looking at Shen Siyi and Sun Wei as if asking for help, who knew that the young man said again: "By the way, as long as you accompany me, the other two can leave."

After speaking, he glanced at Shen Siyi lightly.

The two school masters who had never been disliked before were very angry, but they had no choice but to disobey the NPC who was in charge of important information, so they had to leave angrily.

Shen Siyi gave Tu Hua a look of "You want to be lucky and be careful of Su Gechi's jealousy", and pulled Sun Wei away: "Let's ask others first, this... you can find a way to deal with it."

Tu Hua looked at the attractive NPC in front of him, wanting to cry but without tears, thinking that appearances are indeed deceiving.He secretly moved the chair out, and sat down tensely: "Sir, please...how can you tell me about the password?"

The man actually leaned over directly, wrapped one hand around Tu Hua's waist from the back of the chair, stared at him affectionately, and slightly raised the corners of his lips: "You have a drink with me."

Goosebumps all over Tu Hua's body, he sat up straight and said nervously, "That... I'm underage."

"Nonsense." The man chuckled, his lips moved close to his ear, scratching his ear with the smell of wine, "You are already an adult, I know."

Tu Hua didn't even care about how he knew his age, he just felt that half of his face was numb from embarrassment.He silently hoped that Su Gechi didn't see this scene, otherwise he would have to rush out and tear this NPC to pieces.

However, this NPC might really be too good-looking. After teasing her a little bit, Tu Hua actually felt that his body was a little weak, and his neck was completely red.In order to prevent the top of Su Gechi's head from turning green, Tu Hua quickly broke free from the man's arm, stood up and said, "Sir, please... show some respect."

The man stared at his face for a while, a satisfied smile suddenly appeared on his face, and he teased softly: "Fool."

After speaking, he reached out and stroked his hair.

Tu Hua was stunned.This movement... this expression...

Sugar Pool? !

Tu Hua jumped away as if his fur had exploded, and stared at his face cautiously for a long time, finding a sense of familiarity in those blue eyes.Just now, I was so focused on admiring this man's appearance that I didn't notice his eyes at all!

Now that Su Gechi has entered the game, how could he allow other NPCs to tease him so nakedly?Moreover, he knew Tu Hua's age, and in order to be alone, he wanted to drive away the idlers and so on, so he chose the best-looking skin for himself, which was indeed Su Gechi's style!

But at first he thought that Su Gechi could only play an NPC in a level, but he didn't expect that he, who had just played Sherlock Holmes, would pretend to be a beautiful NPC in a bar...

The "accompaniment" and "following" he said are really true!

Seeing that Tu Hua had already figured out the ins and outs, the old fox in front of him pretending to be a handsome blond man showed another captivating smile: "Can you sit down now?"

Tu Hua breathed a sigh of relief, and finally sat beside him with peace of mind: "What's the question? I should answer the question correctly before you can tell me the information, right?"

Su Gechi, who was dressed in the skin of a blond man, did not answer his words, but gently raised his chin: "I like young boys like you the most, if you can play dice with me, I will love you more." happy."

The faces of the two were very close. When Su Gechi spoke, the hot air with a faint aroma of wine filled Tuhua's nose. He stared blankly at Su Gechi, although this person was now wearing the skin of another NPC, restrained Due to the limitation of his NPC status, he couldn't get along with him normally, but Tu Hua still read the familiar affection from his eyes.

Through those eyes, he seemed to see Su Gechi's face with a faint smile.

Inexplicably want to kiss.

Tu Hua was taken aback by his own thought, and blushed quickly, "How to play?"

苏格池从兜里掏出两颗骰子，一颗上面只有1、3、6三种点数，一种点数分别占两面，而另一颗只有2、4、5三种点数。

He picked up the 2, 4, and 5 dice, and then handed the 1, 3, and 6 dice to Tu Hua: "We both use two dice to compare the points, and whoever has the bigger one wins. Two out of three games win. If you win, I'll tell you about the lockbox."

Tu Hua picked up the dice with sides 1, 3, and 6 and looked at it for a while, then raised his head and said, "This game is not fair."

Although the NPC in front of him is Su Gechi, the game content set by the system cannot be changed by Su Gechi. He even has to conduct behavioral dialogues according to the system character settings, which means that he cannot intervene in this unfair game. Follow the rules of the system.

This is probably also the reason why Su Gechi wanted to sneak into the identity of this NPC.

I'm afraid that the original setting of this NPC is to tease the challenger, and Su Gechi decided to take advantage of his own people in order to avoid being painted by someone who doesn't understand.

Unexpectedly, the system is not only cruel now, but has also learned to play hooligans!But thinking about it, if the person in front of him wasn't Su Gechi, Tu Hua would probably have punched him right now, and he definitely wouldn't be able to take advantage of it...

But this does not mean that Tu Hua will submit to unfair rules.

他面前的这颗骰子上只有1、3、6三个数字，而苏格池的骰子是2、4、5，如果用这两颗骰子比大小的话，涂化的胜率显然比苏格池低。

There are a total of 9 possibilities for two people to roll the dice, which are (1, 2) (1, 4) (1, 5) (3, 2) (3, 4) (3, 5) (6, 2) (6, 4) (6, 5).

Among the nine possibilities, there are only 4 situations where Tuhua's points are greater than Sugechi's, that is to say, Tuhua's winning rate is 4/9, while Sugechi's winning rate is 5/9.

This is clearly an unfair game.But the character setting of this beautiful blonde NPC obviously doesn't want to admit this: "That's how interesting it is."

This expression is really as bad as it is.If it weren't for the soul of Su Gechi inside, Tu Hua would have solved it by force.But now he has no choice but to succumb to this unfair rule and pin his hopes on his poor 4/9 winning percentage.

Tu Hua was the first to roll the dice: 3 points.Su Gechi smiled, then threw the dice: 2 points.

In the first round, Tu Hua won.

Tu Hua breathed a sigh of relief and threw the second round.The fate is that this round directly casts 1 point.

In the second round, Su Gechi won.

In the third round of the decisive victory, Tu Hua prayed for a long time, rolled the dice devoutly, and kept chanting "6 o'clock" in his mouth, but the dice stayed at the position of 3 o'clock.

Su Gechi's expression was very calm. He pinched the dice with two slender fingers and tossed it lightly. The dice stayed at 5 o'clock.

Two wins out of three, Tu Hua lost.

Fortunately, losing the bet in this game will not eliminate him, but there is one less basis for judging the password.

But Tu Hua couldn't hide his frustration.Su Gechi on the opposite side smiled lightly, reached out and pulled Tu Hua into his arms, and looked down at him: "Although you lost, I can still tell you the information about the password box."

Tu Hua's eyes lit up immediately: "Really?"

Su Gechi approached him slowly: "Unless you kiss me."

Tu Hua froze for a moment, staring blankly at the person in front of him. Is this sentence a character setting of the NPC or Su Gechi's original intention?
