"Don't be a fool of heroes," Yan Qingqing said, "I'd better listen to your uncle." ”

Zhao Chuyun continued to calculate and practice, there was almost no room for a piece of papyrus, Yan Qing glanced at it roughly, only to feel that it was more of a headache than the calculus of the university, she silently took out the booklet from the small baggage, handed it to Zhao Chuyun and said: "If it is not enough to write, there is still it here." ”

Several people were relatively silent for a long time, and only the rustle of the pen could be heard in the entire secret passage.

As soon as she stopped, the feeling next to her could not compare to hunger, Yan Qing's stomach had protested several times, she touched it uncomfortably, and sighed deeply, when will this day of displacement pass?

Seeing that Zhao Chuyun's pen was about to write Mars, he suddenly saw him throw the pen and paper, and leaned back.

Yan Qing asked: "It's done?" ”

Zhao Chuyun spread his hands: "There is no solution, it really can't be done, so you can only break through." ”

I didn't expect Zhao Chuyun to break the jar and fall, Yan Qing really wanted to rush over with him, but the protagonist has an aura, and it's not so easy for her to survive as cannon fodder, so she still can't be impulsive, but what is the way to crack this mechanism?

Yan Qing suddenly thought of something in modern times, and she said, "You say, is there a possibility that when the stone pillar comes over and coincides with the wall on one side, we will open it..."

"Don't be kidding, this wall is so heavy, how can it be broken by manpower alone?" Fang Yi remained at the same level and continued to pour cold water.

Yan Qing smacked his lips unpleasantly: "Listen to me first, we have a thing called 'jack' over there, which mainly uses the mechanical principle, and this thing can even hold up something weighing two tons." ”

Zhao Chuyun became interested: "What is the mechanical principle you are talking about?" ”

Yan Qing scratched his head: "I don't know how to explain this to you." ”

She picked up the pen and paper on the ground and drew a jack in a rough shape: "It adjusts the bottom edge of the upper and lower triangles by means of a lead screw and a nut in the middle, so as to lift and lower the height." ”

"Just like a ladder, when the angle between the two arms of the ladder is smaller, the ladder will be higher, and the larger the angle between the arms of the ladder, the lower the ladder."

Yanqing's painting is very powerful, and with her explanation, several people understood it at once.

It's just that Fang Yi and Mu Xiaoba don't often come into contact with the mechanism, and they doubt that such a small triangle combination can lift a few tons of weight, Fang Yi said: "I understand the operating principle you said, but this thing can lift a two-ton weight?" ”

Yan Qing Fang Yi and the two said: "Then think about the trebuchet you use in battle, why can two people lift a boulder weighing a hundred catties or even a thousand catties?" ”

Seeing that the two of them were stunned, Yanqing continued to carry out ideological education: "You can't imagine it, it doesn't mean that it doesn't exist, young man, don't be so pedantic in your thinking, you must know how to transform." ”

Zhao Chuyun said: "Hengmu, aggravated but not bending, extremely victorious, the right school crosses the rope, scratches without additive, and is extremely invincible." The weight of the weight on its side must be beaten, the weight is similar, the balance is the short standard is long, the two plus the weight is similar, the standard must be down, and the right is also marked. ”

Yan Qing didn't understand why he suddenly came to recite the text in Chinese, and looked at him with some puzzlement.

Zhao Chuyun said with a smile: "This is recorded by Mr. Mozi, he means that the reason why the weighing rod will be balanced when weighing objects is that the 'this' is short and 'standard' is long, and the superposition of the weight of one side will inevitably require another mutual weight balance, so if you want to save effort, you have to share the transformation through various machinery, and the jack is used to shrink the two arms by twisting the screw in the middle, it seems that the operator does not use much effort, in fact, the force of the two arms is still the same, perhaps it is the mechanical principle you said." ”

He got it again? Yan Qing simply admired his transformation ability, if Zhao Chuyun was born in the 21st century, he might be able to get a top science student in the college entrance examination.

Zhao Chuyun said: "I heard Uncle Ning say that the underlying principle of all organs is nothing more than leverage and cycle, without exception, so it is normal to pull out a thousand catties." ”

Fang Yi saw that he had said this, and he couldn't refute it: "Since what you said is so fanciful, take out that thing and take a look." ”

This is to the point of Yanqing's death, she has no choice but to spread her hands, too, where did the jack come from in this broken place, is it possible that she still expects Zhao Chuyun to change out on the spot?

As a result, Zhao Chuyun really said so, he raised his eyebrows: "I can make one now." ”

Yan Qing's jaw dropped in surprise: "Ready-made?!" ”

Zhao Chuyun nodded: "The protective armor on my body is removed, and it can be done evenly." ”

Yan Qing knew that there was something to do when he heard his tone, so he couldn't help but answer: "But..."

"But even if you make a jack, it's not once and for all, you think about how operable it is."

Yan clearly understood that the mechanism between the stone wall and the stone wall was not connected in series, so even if they blocked the first block, the second block could still move autonomously, so when that time came, it was impossible for any of them to go back and take off the jack and continue to open the second block.

After thinking about it for a long time, it was still in vain.

Deflated, she collapsed on the ground, wanting to cry without tears.

Fang Yi continued to be yin and yang: "I thought I had come up with some tricks, but it turned out that I couldn't get out." ”

Yan Qing has no strength to talk to him poorly, at this time, it would be good if there was a stinky sock that could be stuffed in his mouth: "Fang Datou, saying two words less will kill you, right?" ”

After waiting for a long time and not hearing Fang Yi's counterattack, Yan Qing was curious, and when he sat up, he saw that Fang Yi's mouth was sealed, and it was still the little Mingmu Qiu that Mu Xiaoba had given him earlier.

Fang Yi whined and asked Mu Xiaoba to recall Mingmuqiu, Mu Xiaoba was so anxious that he sweated out, but that Xiaomingmuqiu didn't move at all, for a long time, Mu Xiaoba was stunned and said: "Uncle, it seems to recognize the master." ”

Confessed to the Lord? Clear your doubts.

Mu Xiaoba looked at Yan Qing: "Sister Yan, do you try?" ”

Yan Qing was puzzled: "How to try?" ”

Mu Xiaoba said: "You just think in your head, just let it come back." ”

Yan Qing pursed his lips and nodded, and said tentatively: "Return... Come?"

The next moment, I really saw that the little thing was removed from Fang Yi's mouth and flew back to Yan Qing's side.

Fang Yi's lips were red, and he was suffocated.

"Poofha," Yan Qing burst into laughter, laughing so much that his stomach hurt, and it took a while to wipe away the tears from the corners of his eyes, "It's really good, how about it, Fang Datou, your mouth stinks nemesis." ”

Fang Yi was so angry that he couldn't do it, the little Mingmu Qiu Mu Xiaoba who had just stayed to protect him had already taken it back, otherwise maybe he could recognize a master or something, he snorted coldly, and scolded with a face: "I'm really convinced." ”

Yan Qing's eyebrows were crooked, and he pulled Zhao Chuyun: "Look at his stupid appearance, it's funny!" ”

Zhao Chuyun was helpless, and shook his head with a smile: "Be careful." ”

Yan Qing waved his hand: "It's okay, I'm just having fun in the middle of suffering now, can I laugh more." ”

Suddenly, something flashed in her mind, and she immediately asked: "By the way, there is a question I want to ask, Zhao Chuyun, how does this stone wall work?" ”

"Running?"

"That's why the trap is triggered?"

"Because of the weight," Zhao Chuyun said, "there is a sensor system in this floor tile, and when it reaches a certain weight, the mechanism will be opened." ”

"That's right!" Yan Qing clapped his hands, this ancient is not the digital age, naturally there is no trigger mechanism such as body temperature, so you can only feel the weight of the human body, so you say, "This is the key, as long as we don't touch it, don't let it sense, can't the mechanism be opened?" ”

Zhao Chuyun shook his head: "If you rely on the hexagram to deduce the number of steps you walk, you can avoid the induction system, but at the moment, what the people who set up the formation are leaving behind is a dead end, and no matter how we go, we will touch the mechanism." ”

Fang Yi said: "If you don't feel it, you can't walk over with your feet, is it difficult to fly over?" ”

The corners of Yan Qing's lips raised slightly, and he smiled: "That's right, fly over!" ”

Zhao Chuyun also thought of it, so the two looked at Mu Xiaoba in unison.

Yan Qing patted him on the shoulder and smiled with a sly face: "Little Ba, it's up to you!" ”

"Ah, me?" Mu Xiaoba was a little dazed.

Fang Yi also understood, and rolled his eyes: "You can do it with my nephew." ”

Yan Qing smiled sweetly at Mu Xiaoba: "Xiaoba, can you build a bridge with Mingmu Qiu?" We're going in mid-air, and we can just let a few of us through. ”

"Absolutely!" Mu Xiaoba's eyes were firm, "It's great that I can help." ”

Yan Qing was very relieved in his heart, and his eyes showed admiration, what a good boy with good roots!

"I'm sorry for you." Zhao Chuyun coughed and reminded Yan Qing to retract his blatant eyes, why do you keep opening the screen to children? Isn't his face enough to see? He suddenly realized that the effect of the pure love fruit seemed to be getting smaller and smaller.

was glared at by Zhao Chuyun, and Yan Qing retracted his gaze aggrievedly, why is this man getting more and more jealous?

It is not a small amount to build a rattan bridge from here, Fang Yi sighed and reminded: "Little eight, do what you can." ”

Mu Xiaoba nodded: "I understand, uncle." ”

He first released a vine out, almost a cup of tea, the vine grabbed a strong and reliable thing, Mu Xiaoba vigorously pulled the vine back, made sure that the thing he grabbed was very strong, and then began to weave the vine into a net, and soon, a rattan bridge was erected.

"That's it." Mu Xiaoba was dizzy for a while, covered his head and took a few steps back, and was supported by Zhao Chuyun.

Seeing that Yan Qing's hand stretched out in mid-air was retracted, Zhao Chuyun hooked his lips slightly, fortunately, his eyes were quick.

Yan Qing didn't notice it, but asked Mu Xiaoba with concern: "Are you okay?" ”

Mu Xiaoba shook his head slowly, he couldn't say anything weak, and the vines on half of his face were much less, only a few were still wriggling on the white bones.

Fang Yi said: "He's fine, it's just that the consumption is too great, and he is a little distracted, just take a rest." ”

Yan Qing nodded: "It's hard work." ”

"Now that the bridge has been built, it's only a matter of time before we go out, so let's rest again."

Zhao Chuyun leaned Mu Xiaoba against the wall: "It's okay." ”
