After Wu Fan obediently carried back a big tree from the woods and inoculated it in the open space in front of the house, Wu Fan finally redeemed the food box from Zhang Liang, which is really gratifying!

"Congratulations, congratulations!" On the way back, Wu Huan became more and more unhappy the more he thought about it, and finally couldn't help but throw the branch that he had broken off casually in the direction of Zhang Liang. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"You deserve it!" Shi Lan snickered.

"I said Shi Lan, you are laughing at me, so give me back the gem that you don't know where to hide. Wu Huan looked at Shi Lan angrily.

Shi Lan immediately turned her head to look straight ahead, walking seriously.

"It's really... Wu Huan tilted his head, and after looking at Shi Lan twice, he still didn't see where the gem was hidden.

As soon as he put the thing behind him, it disappeared, and when Shi Lan casually put Wu Huan's gem behind him, Wu Fan looked around Shi Lan in the next moment. I was stunned that I didn't see the figure of the gem, and my clothes didn't bulge.

It wasn't until Shi Lan herself took it out from behind her, showed it to Wu Huan and put it back that Wu Huan, who was seriously suspected of Shi Lan secretly throwing away and hiding somewhere else, was speechless.

They still think it's normal, it's obviously not scientific at all.

But I can hide things myself, Wu Fan suddenly pondered, and he can hide a lot more than them, big things.

Oh haha, when I think about it like this, Wu Fan instantly feels balanced. And why is there still a sense of superiority. Hey, hey, hey...

Shi Lan said, interrupting Wu Huan, who was about to look up to the sky and smile: "Didn't you say that you would exchange a lot of diamonds with me?"

"Hey, when did I say this, why don't I remember?" Wu Huan shrunk his neck, twisted his head to the side, and took a step away from Shi Lan.

Wu Huan cried silently in his heart, blaming himself for being too confident, too arrogant, and too ... On the way to get a tree, I told Shi Lan... Ah, my heart aches when I think of this, and my heart is tired.

Shi Lan came to Wu Huan's side again, walking surprisingly calmly, calmly overdone.

"Shi Lan, I really didn't expect this to be much more difficult than I imagined. Wu Xuan sighed and took out a black stone the size of an egg.

Please don't care why it went from a small pile of black powder to such a big one. Wu Huan will tell you to order a little more tree by the way when picking trees?

If it weren't for Shi Lan to stop him, he might have changed a lot, Wu Fan thought so.

Fortunately, it was stopped! Otherwise, there will be another tragedy similar to the one behind a certain house a certain year ago!

Ahh!!h

Wu Huan exhaled happily: "Ah, it seems to be quiet." ”

Shi Lan turned her head curiously, looked at the thing in Wu Huan's hand, glanced at it and couldn't help but say, "It's so ugly!"

"Uh. Wu Fan paused: "Indeed." ”

Wu Huan explained the stone in his hand: "Graphite: the softest known ore in the world. ”

As soon as Wu Huan finished speaking, Shi Lan sighed softly. This grade has dropped to the end in an instant, and it's still so ugly.

"But people have a lot more to do. It can be used for many more purposes than a complete diamond! Wu Fan couldn't help but defend the poor graphite gentleman.

"What's the use of this stone called graphite?" Shi Lan couldn't help but ask.

Wu fantasized for a moment: "Pencil lead, used for writing and drawing." ”

"Oh. Shi Lan understood.

“。。。 Wu Fan was silent next.

"Huh, what else?" Shi Lan asked after waiting for a while, and then rolled her eyes: "Don't tell me you forgot again." ”

"It's not that I forgot, it's that I don't know. Wu Huan nodded: "Those are specially processed, I don't even know how to make pencil leads, but I know that its raw material is graphite, just like I know that the raw material of paper is wood, but even if I mix the wood into thin mud, I can't get it out." I don't know how to do it. ”

"Oooh. Shi Lan nodded.

Then Shi Lan continued to walk, and Wu Huan followed Shi Lan and lowered his head and began to prepare for the huge project of turning graphite into diamond.

Wu Huan suddenly found that compared to arranging his own carbon atoms, it was much easier to make it with high temperature and high pressure!!

"Uh!" Wu Xuan grabbed his grip, but he didn't know how to get high temperature and pressure. The high temperature, the fire that you make by yourself is more than 1,000, which is super powerful, but it is not enough. The high pressure is completely far away, how can the high pressure be able to deform things, but it is not enough, so Wu Huan felt that he should be obedient.

Wu Xuan couldn't help but go crazy and said: "Shi Lan, I have a dense phobia, ah!!hh This is definitely not something that can be solved by tens of thousands! This can be said to be billions, trillions, trillions, trillions... Countless trillions of billions of dots, CCC... I'm crazy, one dot connects four dots, one dot connects four dots, one dot!" Wu Huan said this, and decisively hit the wall.

And Shi Lan was holding the food box in the corner, watching Wu Fan cover his mouth.

Wu Huan squinted his eyes and rubbed his forehead, don't think that Shi Lan, if you cover your mouth, I won't see the corners of your mouth hooked!

When he came to Shi Lan's side, Wu Huan couldn't help but complain again: "Shi Lan, why don't you tell me!

Shi Lan changed the food box to hold it: "At that time, this hand was holding the food box, and this hand didn't reach it." To remind you that you've crashed into it. ”

"Okay, good, Shi Lan, you won. Wu Huan raised his hand, and suddenly found that he had unconsciously arrived at the path next to the library pavilion: "Ahhh

"What's wrong!" Shi Lan looked at Wu Huan, and then at the Library Pavilion. I don't know if Wu Huan is swollen today, and he always cares about the library pavilion that he usually ignores directly.

"Ahhh。。。h Wu Fan was frightened again.

"Don't always be scared when you're fine! Shi Lan said calmly.

"Burning books and pit Confucianism!" Wu Fan said even more frightened, suddenly realizing what to look around, fortunately no one, pulled Shi Lan aside under the big tree and whispered again: "Burning books and pit Confucianism... When I heard Zhang Liang say that there are many kinds of books here. I felt it faintly. This is probably the book they burned. ”

Shi Lan was silent for a moment and said, "Book burning pit Confucianism, it sounds so brutal... What's more? ”

"Uh... This one. Ying Zheng did it, Li Si came up with an idea... It has a great impact on future generations. Wu Xuan nodded and said.

"In short, you don't know. Shi Lan rolled her eyes: "What can you put in your head!"

"Ahem, it's not that I don't know! This is the heavenly machine, don't you know!" Wu Fan roared at Shi Lan.

Shi Lan covered her ears, which were shocked by Wu Huan, and said, "Tianji, is it delicious?"

"Hmph. Wu Huan turned his head angrily, turned his head and blinked his big eyes: "So I want to learn Fu Xizhi." ”

"Copy, what is this?" Shi Lan wondered.

"It's learning to learn to learn!" Wu Fan said.

"Oh, not copying?" Shi Lan asked.

"Of course it won't be a copy. Wu Huan pinched his waist and said.

"Which copy is that?" Shi Lan thought.

"Shi Lan, which ear is listening to copying!" Wu Xuan shouted.

"Both ears heard. "Shi Lan Dao.

Wu Fan said word by word: "Learn from the West, learn from the West." Learn to learn to learn zhi. ”

"Oh, I see. Learn to copy. Shi Lan nodded.

"Okay, Shi Lan, you win, I want to copy. Wu Huan let go of his shoulders.

"Good. Shi Lan said.

"Shi Lan has already investigated, and there is no one around. Wu Fan said, a blue light surrounded him and Shi Lan: "Take advantage of now!" Wu Fan shouted and pulled Shi Lan to the side of the library pavilion, and entered the library in a flash.

“。。。 Shi Lan looked at Wu Huan, who let go of herself, and pointed to the door with a thin crack exposed: "Didn't I say you didn't see that the gate was not closed just now?"

Wu Fan looked at the gate, and the six blue dots that appeared on his head disappeared in line one by one, until they were gone, Wu Fan turned his head and waved his hand without looking at the gate: "Oh, anyway, it's already in, don't care about those little details!"

"Ahh Let Wu Huan, who was about to scream, stop and look at Shi Lan.

"I said Shi Lan, don't rob me of my screams, okay. Wu Xuan looked at Shi Lan dissatisfied.

"I knew you were going to scream, so I'll help you scream first. "Shi Lan Dao.

"Okay, if Shi Lan calls it, I won't call it!" Wu Huan spread his hands and began to look at this library pavilion: "Ah!"

"Didn't you say you wouldn't call it!" Shi Lan said, putting the food box aside.

Wu Huan touched his head and said, "Hehe, get used to it." ”

“。。。 Shi Lan said that this library made me have a faint sense of déjà vu. It seems to have been seen somewhere. Wu Huan glanced at it a few times and said.

"Where have you seen it?" Shi Lan asked, looking left and right.

"!!" Wu Fan looked at the top of the library pavilion, only the walls were surrounded by books and the middle was indeed empty, not separated layer by layer as Wu Fan imagined, which was exactly the same as the room pattern of the Yin and Yang Family: "The Yin and Yang Family... But this one is too small, it's really weak. It's not half the size of the Yin and Yang family. ”

"Okay. Shi Lan spread her hands, took out a bamboo slip placed aside, spread it out and looked at it a few times before putting it back.

Wu Huan watched Shi Lan's movements, and also picked up the bamboo slip beside him decently and spread it out. After thinking about it, with the setting that you must fight back, then... Wu Huan turned witfully. After a few glances, I put it back.

"You don't know how to read, what do you open to see? And you were right, but after a turn, it turned around and turned it back. Shi Lan said with a smile.

"I said, Shi Lan, please don't keep complaining that I don't know how to read, okay! Wu Fan spread his hands.

"Shi Lan, I'll take you to the top, and the top is full of good things. Wu Fan stretched out his hand to Shi Lan.

"Okay~" Shi Lan put her hand on Wu Huan's hand.

Wu Huan clenched Shi Lan's blue light and jumped up. Until he reached the top, Wu Xuan stopped and floated in the air with Shi Lan.

"Shi Lan, let me tell you that the Yin and Yang family is very high, and the bottom is dense, and each layer is composed of a transparent floor. At the beginning, I appeared directly on the top, which scared me, and I fell down in an instant... But the forbidden arts above are really powerful. I've looked at the layer below, and I feel like I'm instantly weak. . . Wu Huan pulled Shi Lan to explain the sadness at the beginning.

"Oooh. Shi Lan looked down and nodded, then looked at Wu Huan: "You hurry up and copy, it won't be good for someone to come then." ”

"Yes. Wu Xuan stopped and looked at the blue light around him.
