"Seven years, we spent seven full years searching for documents.

It took a lot of effort to find this place, just to be able to see the exercises cultivated by the legendary martial gods..."

Su San raised his eyebrows, and said in an affirmative tone: "It's the book you just said you wanted." ”

Dahan nodded: "What we said in the inn yesterday, this girl must have heard it." ”

Su San pursed his lips, without the slightest embarrassment in eavesdropping, and even raised his eyebrows, waiting for his next words.

"We came to this place last time, but the fourth child was too reckless, and almost made a big mistake, fortunately we retreated in time, otherwise..."The big man closed his eyes and shook his head slightly.

Su San stared at him, and when he saw that he opened his eyes, he moved his gaze to the metal box, and the meaning could not be more obvious.

The big man also stepped up and took a few steps forward to stand in front of the metal box.

Qian Feng and Qian Cai both automatically moved to the sides, surrounding the big man and the metal box.

Dahan didn't seem to know, or maybe he didn't care at all, he squatted directly in front of the box, stretched out his hand and stroked the pattern on the lid of the box: "The method of opening the box has indeed been recorded." ”

Su San and Qian Zhao also squatted next to him, listening carefully to his words, and looking at the metal box in front of them.

"I was fortunate enough to read it in a book, but the way it was written was really hard to understand."

When Su Sanzheng heard the key, Dahan didn't say anything, which made her a little unhappy, and turned her head to stare at Dahan: "Go on!" ”

Dahan stared at her for a moment before continuing, "The air pressure on the outside is greater than on the inside. ”

Su San squatted on the ground, touched his chin, and suddenly turned his head: "This is the end?" ”

Dahan blinked and nodded: "Well, that's all there is to the book." ”

Su San looked into his eyes, probing the truth of what he said.

The big man was fearless, looking back at her without dodging or dodging, his eyes were clear, not like he had told a lie to deceive her.

Su San turned his head, his eyes rolling, thinking about what he meant by his words that had no beginning and no end.

"Black Dragon, you are well-informed, do you know what this sentence means?"

"Well, I don't really know, but my friend drank too much that day and told me...

It was the woman who said something inexplicable to him, and among them was the pressure he said. ”

Su San nodded, so it seems that the unpacking method that Dahan said may be left by this woman, after all, even an old man like Heilong doesn't know the word pressure, so there is only that woman.

Unless, of course, there are others like her...

She sighed lightly, got up and circled around the metal round box twice, thinking about the pressure in her head, and the most classic case should be the water cup.

When the cup is just filled with hot water, the gas inside the cup is as hot as the water, and when the lid is closed, the air pressure is equal to the external air pressure.

But when the gas inside the cup cools, the air pressure inside the cup decreases, and the lid naturally cannot be opened.

"But that's talking about closed containers like glasses!" Su San touched his chin: "Could it be that this metal round box has reached a sealed state?" ”

After two laps around the box, she returned to the front of the box and fell into deep thought.

"Yawn, maybe you can try the solution to the state you said, in case the blind cat touches the dead mouse, it will be opened." In Xuanyu, the black dragon yawned and said with a wistful expression.

Su San suddenly brightened up, and put down the hand that was touching his chin: "Yes, try it and you'll know if it works." ”

"I thought about it." She slapped her head and looked back sharply, startling the big guy.

Qian Zhao and Dahan stepped forward with interest, stood on her left and right and said in unison: "What method?" ”

"Pry" Su San raised his index finger, pretending to respond mysteriously with only one word.

The money trick smashed the mouth, and he immediately lost interest: "I tried it just now, but I can't pry it open at all." ”

Su San pursed his lips and smiled, patted him on the shoulder, and ordered: "You just listen to me, you will do whatever I tell you to do." ”

Qian Zhao looked disbelieving all over his face, Su San pulled the corners of his mouth and stopped looking at him, and directly commanded him: "Dagger." ”

Qian Zhao took out the dagger and handed it to her suspiciously.

Su San took it without looking at it, squatted down, and pinned the dagger to the connection between the lid and the box.

After turning around a little, there was a faint sound of deflation in the box, Su San's eyes lit up, and then there was a different kind of hissing sound.

She paused in her hand and drew her dagger directly.

pursed his lips and got up expressionlessly: "No." ”

"Isn't it quite confident..."

Qian Zhao just wanted to squeeze her two sentences, but when he saw her depressed expression, he immediately retracted what he wanted to say next, and changed his tone: "It's okay, everyone can't open it anyway, you just try, it's okay if you fail, isn't it Ah Cai." ”

"Ang" Qian Cai responded perfunctorily.

"Uncle, think about what else is recorded in that book." Su San turned his back to the big man and asked.

Dahan didn't think about it, so he replied directly: "No." ”

Su San turned her back to everyone, her eyes were dark, and after two seconds, she turned to look at Dahan: "Why don't you try it, which box to open, which one is yours." ”

The big man looked at her suspiciously, but she didn't have any other expression.

He nodded, hesitantly looking at the others: "Then I'll try..."

Qian Feng raised his head, he didn't have any opinions.

I saw that the big man suppressed the emotions on his face, and solemnly stepped forward and squatted in front of the metal round box and tinkered.

"Click" The big man held the lid of the round box and turned it twice, and the round box made a crisp sound.

Su San listened to the crisp voice, his eyes narrowed, he waved his hand at a few people behind him, retreated to the side of Qian Zhao, and said softly: "Watch the show!" ”

Qian Zhao turned his gaze at Su San and Dahan in confusion.

After a while, he got the answer!

As soon as the round box was opened, there was nothing inside, so the big man anxiously reached in and wanted to get the things inside.

Su San gritted his back molars, raised the corners of his mouth, and said to the black dragon in his heart: "This person is really stupid, how can that woman's things be so easy to get..."

The black dragon yawned: "You are not fine, you two are half a catty, you are cheap, you will sell well!" ”

Su San was not angry, the corners of his mouth were rising more and more, and he saw that the big man's hand was getting longer and longer...

At the edge of the box, a black snake suddenly appeared, and its soft body wrapped around the big man's arm and spiraled upward.

said that it was too late, and the next second the snake body directly wrapped around the big man's neck, the snake's head stretched forward, and his eyes looked at the big man...
