(Foreword)

Cold ice can't break the water, and dead wood can meet spring again.

I looked up and saw a person standing on the cliff, eight feet long, with a face like jade, this person stared intently, a folding fan in the book, constantly flapping in his hand, staring intently. It seems to be thoughtful, but it is difficult to speculate. It seems that this person is Lu Xun, the new governor of Jiangdong.

I don't know if what he is thinking about at this time will be my plan, I can't help but smile, it shouldn't be possible. I returned to the camp where our army was stationed from the foot of Wu Jun Mountain.

"General Cheng, is there a good way to attack the enemy in this exploration?" Wu Ban asked anxiously.

"But there is a strategy to control the enemy, let me discuss it carefully." I replied confidently.

"Cheng Yin, what do you think of?" Professor Wu asked from the side.

"I've just observed the terrain nearby, it's steep, it's really hard to attack, but we can do it another way." Before I could finish speaking, I was interrupted by Professor Twilight.

"Another way? How to attack? "Professor Twilight was anxious to know what I could do to attack this treacherous mountain.

"Actually, you also have the credit for this method." I paused deliberately.

"Mine? What did I pay attention to? Professor Twilight was confused.

"Didn't you say that you know the laws of physics? Come and see. "I took out the drawings in my pocket, and said that this paper and pen were still asked by Cui Li during the battle of the three generals, but I didn't expect them to come in handy at this time." This is a simple drawing based on the topography of the place, this is the peak where the Wu army is stationed, and under this peak is a clearing field, and on the opposite side of the peak there are dense trees. ”

"Cheng Yin, there are still a lot of numbers on it." Lin Yun's observation power is also very powerful.

"That's right, I got a rough estimate of the height of the cliff and some other data." I said, pointing to the numbers on the paper.

"Do you want to ......," Zhang Han's eyes widened, and he stopped talking.

"That's right, the mountain is so steep that it's almost impossible for our army to attack it. Moreover, Wu Jun waited for work at ease and could not hold out. So, in this case, we might as well build machinery to attack the mountain. I slammed my hand on the table, but there was no sound.

"Manufacturing machinery? Cheng Yin, you're not joking, are you? How can we make machinery in this place? And what do we take to make it. Don't forget, this is a 'virtual world'! Professor Twie was a little emotional when he heard this idea.

"This ...... It's on the ...... Just kidding, I'...... How do we ...... How...... It is possible to manufacture ...... Out of machinery? "If it weren't for this staccato voice, I wouldn't have realized that Hu Zaide was here.

"Yes, Cheng Yin, this idea is novel, but with our current situation, it is really difficult."

Actually, when my idea was formed, I knew it would be what it is now, and it was difficult for people to approve of my idea, and it was true that it sounded a bit exaggerated at first.

"It's a difficult idea to implement if it were just me, but we're a team now, and it's not out of reach for us." I turned to look at Zhang Han and said, "The last time you repaired the sightseeing car, I knew that you were very good at mechanical operation. I'm sure that some mechanical design of wooden structures will not be difficult for you. "Zhang Han didn't answer my question, but I got the answer I wanted from his eyes." Professor Wu and Professor Du Jiang must have come up with some physics-related knowledge, and finally the calculation and analysis of the data, I believe that Lin Yun and Lecturer Hu will be able to complete it easily. ”

"Maybe you have some truth in what you say, but there is one of the most critical problems, this is the 'virtual world', and it is difficult for us to pick up a cup, let alone build a wooden machine." Professor Du Jiang analyzed the problem very thoroughly.

"Moreover, how can we make a certain scale of mountain tapping machinery in a short period of time?" Lin Yun asked anxiously.

"Military ...... Difficult ...... in the army Isn't there an attack...... Siege and the like... Catapults? Hu Zaide looked at General Wu Ban.

"Catapults were too large for mountain marches to transport, and they were never used for mountain raids." Wu Ban's face was embarrassed.

It is true that in ancient times, there were indeed siege equipment, but most of them were bulky, time-consuming to assemble, and inconvenient to use, so it was almost impossible to manufacture siege machinery according to local conditions. But now is the critical time, and we only have one try.

"General, are there skilled craftsmen in the army?" I asked Wu Ban.

"Since Zhuge Kongming became prime minister, he has been good at studying clever things, so there are many skilled craftsmen in the army." Wu Ban said.

"Great! Zhang Han, how long does it take to design mechanical drawings that can attack mountains? "My confidence is back.

"One day is enough, it's not that difficult, and Professor Wu needs to help them in the calculation of some leverage." After Zhang Han finished speaking, he put on cool headphones again.

"The calculation of this lever is a trivial matter, but where can I find the materials for this fabrication?" Professor Twilight looked at me.

"The materials for this machine have been prepared for a long time." I pointed to the opposite side of the mountain.

"I see!" Professor Twilight finally smiled.

It seems that everything is ready, and my idea has finally been approved by everyone.

"In that case, Ben will go and send someone to prepare the required materials." After Wu Ban finished speaking, he left first.

"Cheng Yin, you still have a way!" Professor Wu praised.

"No, no, I still need everyone's help." I hurriedly excused myself.

"No, I always didn't believe it before, but this retreat is not less." Professor Twilight said with a smile.

………

………

Suddenly, Lin Yun looked solemn and didn't say a word. It stands to reason that we have already thought of solutions to all the problems, I don't know what Lin Yun is still thinking about? Is there anything else we haven't thought of?

"Lin Yun! Lin Yun! I called her name, but she didn't respond.

Lin Yun !! What happened to you? I raised my voice again.

"Ahh I... I just suddenly felt weird. "Lin Yun's observation ability has always been very powerful, there must be something wrong.

"What's wrong? Any questions? My tone was low.

"Didn't you notice?" Lin Yun's tone was a little mysterious.

"What's wrong?" Professor Twilight asked.

"Do you think a military general of the Three Kingdoms period can read Arabic numerals on paper? We have said so many things that are not from this period, but why Wu Ban does not have the slightest doubt, and it seems that he can understand it. Lin Yun's eyes widened.
