How to break into a math book

When Tu Hua picked up the playing card, Captain Jack's face suddenly turned ferocious.He rushed over to snatch it, with a very anxious look: "This does not belong to you!"

Tu Hua dodged subconsciously, vaguely feeling that Captain Jack's attitude was not right: "Is there any meaning to this playing card?"

Captain Jack's face froze suddenly, he took a step back, his eyes dodged a bit: "It doesn't make any sense!"

Tang Bo also asked strangely: "Then why did you rob?"

Captain Jack didn't speak, and seemed to glance in Mr. X's direction, and said after a while: "If you want... just take it!"

After speaking, his body slowly disappeared, and the familiar music sounded in his ears again. In the blink of an eye, the island disappeared, the waves disappeared, and the beach gradually faded.There was a wooden floor under their feet. Tu Hua raised his head and saw a piano in the corner, playing beautiful music.

They went back to the music classroom.

【Ding--】

[Challengers Tu Hua, Sun Wei, Tang Bo, and Wang Boyu sailed the world through side missions, and received a reward: a fragment of Hippahos's lost string watch. 】

Wang Boyu suddenly appeared in the faint classroom out of thin air. He was lying on the ground, looking very painful, his limbs stretched out his teeth and claws, and there was a muffled moan in his throat.

The three of Tu Hua looked down at him strangely.

After a full five seconds, Wang Boyu stopped.He lay on the ground like an octopus, and raised his head in bewilderment: "What... what's going on?"

"What's the matter with you?" Tu Hua asked him back.

Only then did Wang Boyu see the surrounding scene clearly, jumped up crying, hugged Tu Hua and whimpered, "I was in the sea just now, and almost drowned! Uuuuuuuuuu Captain Jack, this inhuman thing, finally threw me away too. Into the sea!"

Tuhua: ...

Fortunately, they successfully saw through Captain Jack's trick in the end, passed the level, and obtained the reward of string table fragments.They've got two fragments so far and are four shy of the total.

However, according to the law given by Mr. X, the probability of their next mission to get fragment rewards is only 60%. Even if Tu Hua chooses the right level related to trigonometric functions, the probability of obtaining fragments can barely increase to 65%.

The stakes are high.

Tang Bo suggested: "Why don't we leave the team now and go through the level alone. In this way, as long as each of us successfully clears the level once, we can get 100% of the fragments, plus 4 fragments, we will complete the main task."

But Tu Hua couldn't help but recall Captain Jack's attitude just now.He seemed to care a lot about that last card, and didn't want to be painted to take it away.But in the end, when Tu Hua questioned him, he obviously didn't want to pursue it, probably because he was afraid that he would make too many mistakes and reveal some important news.

And most importantly... he cast one last glance in Mr. X's direction.

Tu Hua turned his head and stared at Mr. X, could there be some shady deal between these two...

"What kind of eyes do you have?" Mr. X shrugged, "It seems like you are going to eat me."

Tu Hua quietly called him to the corner, and asked him in a low voice: "About the probability of fragments appearing...you didn't lie to me, did you?"

Mr. X raised his eyebrows: "You don't believe me?"

Tu Hua thought for a while, Mr. X seemed to have no position to lie to him.Although this NPC has a bad personality, it is not enough to violate the rules of the system and tell lies.

Could it be that he misunderstood?

But why does Captain Jack care so much about that playing card?Tu Hua opened the system backpack, trying to take out the 5 of squares that he brought out from the level, but he couldn't find it after searching over and over again. There were only two pieces of string watches in his backpack.

There are too many doubts...

Tu Hua was frowning in thought, when Sun Wei suddenly said, "There is not much time left."

【Current level: Trigonometric function level】

[Main Quest: The Lost String Table of Hippajos]

[Team challengers: Tu Hua, Wang Boyu, Sun Wei, Tang Bo]

[Obtain string table fragments: 2/6]

【Remaining time: 24:14:34】

"Why are there only 24 hours left?" Wang Boyu asked in surprise.

Tang Bo frowned: "Every one of us has been thrown into the sea, and no one knows how long we have been floating in the sea."

Tu Hua also felt nervous. There were only 24 hours left, and the probability of obtaining fragments in the next level was unstable. Now they had to carry out the mission separately.

Tang Bo opened the team task bar and tried to remove his name, but this time it was not as easy as last time, and a dialog box popped up: [Operation invalid].

"What's going on?" Could it be that each person can only leave the team once?Is it because of the last demonstration operation that Tang Bo can't carry out the task alone now?

But the fact is more serious than they imagined, and the names of other people cannot be removed from the team.This means... It seems that their team cannot be dismantled.

"Why is this?" Wang Boyu wondered, "Can't they be separated?"

Tu Hua frowned: "No matter what the reason is, we can't separate tasks now."

Everyone was depressed, and the hope that had been kindled with great difficulty was shattered in this way.If the tasks cannot be separated, they will never be able to gather the next four fragments. Leaving aside the last 0-probability checkpoint, they may not be able to pass the first 20% and 40%.

And every time a branch level is cleared, the probability of obtaining string table fragments will be reduced by 20%, which means that if they have passed the next level with a 60% probability of obtaining fragments, but they have not obtained fragments, what they will face next The probability of obtaining fragments from missions will drop directly to 40%.

But until the last moment, you can't despair.Tu Hua cheered up and comforted everyone: "We still have 24 hours, which proves that we haven't lost yet. Go find other challengers to inquire first, and there will definitely be a solution."

Tu Hua glanced at the leisurely Mr. X beside him, he must know the problem.But he obviously looked like "you come and beg me", so Tu Hua had to restrain his desire to hug the thigh of this "artificial teleprompter". Even if Mr. X is a free cheat given to him by the system, he must guarantee it The ability to think independently, you can't always want to rely on him.

The four of them planned the next action goal, and prepared to divide into four groups for an hour each to find other challengers to inquire about the news.They were about to leave the music classroom, when they opened the door, they found Shen Siyi standing in the corridor, seemingly waiting for a long time.

When he saw Tu Hua, he showed a trademark smile: "Can I bring money into the group?"

Tu Hua was stunned, he hadn't seen Shen Siyi since Function Guan said goodbye.Tu Hua had really thought about inviting Shen Siyi to break through with him before, but he didn't expect that now he would come to the door on his own initiative, still holding two fragments of string watches in his hands.

Shen Siyi smiled, and handed over the fragments in his hand: "The upper limit of this task team is 5 people, I think you only have 4, mind if I join you?"

Tu Hua turned around to ask his teammates for their opinions. After all, all four of them had gone through the level with Shen Siyi. Shen Siyi's logical ability was obvious to all. Besides, he also brought two fragments to show his sincerity. It was difficult for people to accept him. .

"Have you hesitated for so long?" Shen Siyi shrugged, "I originally planned to go through the level alone, but I couldn't collect the last fragment anyway, so out of selfishness... I wanted to come and hug your thighs."

Tu Huaben had a good impression of him, and after getting the unanimous approval of his teammates, he finally threw out an olive branch in relief: "It's not sure who hugs whose thigh."

Shen Siyi gave the fragments to Tu Hua, and his name was successfully added to the team. He looked at Tu Hua, and suddenly said seriously: "From now on...we are teammates."

His eyes were frank, and Tu Hua understood that after experiencing Li Tao's betrayal, although Shen Siyi didn't care on the surface, he must have been deeply shocked in his heart.In the face of interests, it may be difficult for him to trust anyone.

As for the level of trigonometric functions, if you don't form a team, you can't get to the end alone, so he has no choice but to choose to fight side by side with others again.With Shen Siyi's level of intelligence, he should have observed Tu Hua's team for a long time. He saw the cohesion of this team and the deep friendship between teammates, so he let go of his guard and chose Tu Hua's team.

To be able to fight side by side with such a strong teammate, improving the clearance rate is secondary, what Tu Hua cares more about is the sense of sympathy in which thoughts and souls collide with each other.He was very glad to meet Shen Siyi again.

In addition to the two string table fragments brought by Shen Siyi, they already have four fragments, which is only two pieces away from the total. You can pass the level by getting two fragments in the levels with three chances of 60% and 40%.

It's time to fight back.

This time, Tu Hua chose a level called "Take a walk in the streets of Ming Dynasty".Wang Boyu and the others found it strange that this level seems to have nothing to do with trigonometric functions.

Shen Siyi and Tu Hua looked at each other and explained: "The Ming Dynasty is related to trigonometric functions. my country's first trigonometry masterpiece "Dacai" was written by German missionaries Deng Yuhan and Tang Ruowang during the Chongzhen period of the Ming Dynasty. It was co-edited with Xu Guangqi, a Chinese scholar. This checkpoint is likely to be related to "Datest."

Wang Boyu looked at him in shock: "You know all this!"

Shen Siyi pointed at Tu Hua and smiled: "He also knows."

Wang Boyu looked at them adoringly, his eyes glazed over: "I found that since I came to this game... I always suspect that I am a fool."

Tang Bo patted him sympathetically: "People are valuable to know themselves."

Wang Boyu: ...

[Go to the streets of the Ming Dynasty] The entrance of this level is in the reading room on the first floor of the library. Open the door of the reading room, as if you have traveled directly to the world hundreds of years ago.

Antique streets, old-fashioned buildings, and bustling crowds, wearing long skirts and Confucian shirts, enjoy the natural tranquility in their own time and space.

"Hey...those young people!" An old woman wearing a headscarf by the road suddenly stopped them, "Help me, please?"

Tu Hua looked back, and saw a huge chicken coop in front of the old woman, and a middle-aged man in bunt was standing opposite with a troubled face: "You sell both big and small chickens, what should I count?" Money?"
