The rise of Internet addict Liu Chan

Waking up now, seeing Lu Yusheng standing in front of him with a face full of surprise, Liu Chan suddenly became fat and blushed.

"Uh, Yu Sheng... why are you here?"

Lu Yusheng did not notice that Liu Chan was fishing,

She also breathed a sigh of relief and said excitedly:

"I have known for a long time that the son will not be surprised, it is really good."

Before Liu Chan could react, the little girl knelt down beside him, took out the heavenly book from the cloth bag behind her like a magic trick, unfolded it carefully, and placed it in front of Liu Chan.

"My lord, I have nothing to do on the boat, so I use the knowledge my lord taught me to calculate the itinerary, which is really good.

It is known that the speed of the ship is less than the speed of the water, and the direction of the bow of the ship is perpendicular to the direction of the water flow, the time is the shortest..."

Liu Chan: ...

What?

What was Yu Sheng talking about just now?

Liu Chan finally broke the binary linear equation recently, and is ready to accept Qi Jinjin's praise.

Why... why is Yu Sheng starting to learn a bunch of things that he doesn't even understand?

"These "Physics" books that my son gave me are only my favorite books after "Mathematics".

Of course, I also like "Chemistry", "Biology" and "Geography",

It's a pity that I am so dull that I have never been able to understand the Dao in the book.

These days, I suddenly remembered that I could combine the contents of the book to make a military weapon, so I took the liberty to come to Chengdu without the permission of my son.

Your Majesty won't blame me, will you? "

Liu Chan: ...

Yu Sheng, are you speaking human language?

Fortunately, after rounds of blows, Liu Chan can now face many things calmly.

He smiled slightly, took the physics book handed over by Lu Yusheng, and sighed:

"Yu Sheng is smarter than me,

There are some difficult problems in this book, but I will try my best to answer them for you. "

"Really?!" Lu Yusheng was inexplicably happy,

"I improved the trebuchet by using the principle of leverage and the conversion of potential energy and kinetic energy, but it has only existed in imagination.

Can the prince do me a favor and ask a craftsman to build one? "

Speaking of this, Lu Yusheng stuck out his tongue again, bowed his head and said:

"I know that Meng Lang is joking about this, so please don't punish me."

The war is about to start, how can I help Lu Yusheng make toys like kinetic energy and potential energy?

However, Lu Yusheng had a hard time traveling thousands of miles away, and the manufacturing of weapons was for Liu Chan's plan, so Liu Chan naturally couldn't directly refuse.

Those books that my sister gave contain all the principles of the universe,

Yu Sheng has studied hard for a long time, if he can really apply what he has learned, it will definitely help the big man a lot, so he might as well give it a try.

-----

He thought about it, nodded and said:

"Yu Sheng might as well draw a picture, I'll ask someone to make it first and try it out,

If it can be done, this is a great achievement of Yu Sheng! "

"real!?"

Lu Yusheng was both surprised and delighted.

She also doesn't know how effective her theory can be in practice.

Manufacturing a large trebuchet would consume a lot of manpower and material resources, and Liu Chan was willing to do so, and Lu Yusheng was so happy.

After all, what she has learned so far comes entirely from books,

She has no confidence in whether she can play a role in this world.

"Also, Yu Sheng still has a lot of problems and wants to get the advice of Shizi.

Yu Sheng is really stupid, can you please don't be disgusted with me, please help me... a little bit to solve the confusion in my heart? "

The little girl was worried about gains and losses along the way, for fear that Liu Chan would think that her progress was too slow and blame herself for being too lazy after seeing her.

Unexpectedly, not only did Shizi not blame himself for playing around, but he was willing to test what he learned from the heavenly book for himself.

Shizi is really a good person...

Seeing Liu Chan's affirmation of her hard work these days, she couldn't help biting her lower lip, and said quite moved:

"Thank you, son, thank you, son."

The little girl came all the way, Liu Chan arranged for her to rest as soon as possible,

But Lu Yusheng was still very persistent and first wrote down the problems he had figured out along the way on paper and asked Liu Chan to answer them.

She looked at Liu Chan tearfully, until Liu Chan promised, she cheered and ran to sleep.

Liu Chan shook his head helplessly, looking at Lu Yusheng's beautiful writing, his head grew dizzy again.

"This is completely beyond my knowledge level. I don't know if I can stand it."

Chapter 289 This Is the Real Way of Heaven

If you encounter difficulties and want to find Zhuge Liang,

This is the only way that Qi Jinjin gave Liu Chan.

Taking advantage of Lu Yusheng's rest, Liu Chan ran to Zhuge Liang's residence with a large pile of mathematics, physics and chemistry textbooks, and spread them out in front of Zhuge Liang.

Zhuge Liang, who was planning for Liu Bei's enthronement, was overjoyed when he saw these color-printed pages.

He hurriedly stopped all the work at hand, picked up the book, and read it carefully in front of him tremblingly.

After a long time, he nodded:

"There is such a way to describe numbers, it is really amazing."

"Can the military master understand it?" Liu Chan was quite shocked.

"Hehe, what's so difficult about it?"

Although Zhuge Liang didn't know the symbols on it at all, he could think of the page number in the lower right corner of the page when he observed the book a little.

Contrasted with 1234 and read it a little bit, he also quickly grasped the rules, and then read it in the book, and also understood the meaning of these symbols;

The algebra part is clustered together, Liu Chan's head looks big,

But although Zhuge Liang didn't know how to pronounce it, he contacted the upper and lower sides to think about it, and he also knew that it was a code name.

He can automatically make up other things instead;

As for the other simplified characters, Zhuge Liang's big touch that even birds and insects can read without barriers is not a big problem.

After reading for a while, he quickly got into the rhythm. After reading the first chapter, Zhuge Liang was already deeply addicted to it.

Gee.

Speaking of which, the things that Shizi made before may have some connotations, but Zhuge Liang didn't show much interest after watching them for a long time.

Zhuge Liang was also worried that the heavenly scriptures in Shizi's hands were all the same thing

He thought that as the son said, to promote classics other than traditional scriptures, there must be a corresponding knowledge system and book content.

It must be able to explain to people in detail what is the way to persuade people to go up in the book.

But this junior high school mathematics book brought Zhuge Liang a deep shock.

This is the heavenly book, this is the way!

Zhuge Liang felt as if he had picked up a piece of dazzling stardust from the vast galaxy,

He was immersed in it, unwilling to get rid of it for a long time,

It wasn't until Liu Chan coughed dryly that he came back to his senses.

"This book, the son of the world, would you like to borrow it to have a look?"

"Well, sure,

However, I have given this book to the young lady of the Lu family before, and I still need her permission to borrow the book.

Miss Lu would not refuse if she wanted to borrow from the military adviser. "

Can the lady of the Lu family understand it?

The Lu family in Jiangdong is really pedantic about heaven and man.

Zhuge Liang remembered that his wife Huang Yueying was also very interested in this heresy, so even if he was busy, he could let his wife study it.

This book is of great help to the great man, so one must grasp its mysteries as soon as possible.

"Okay, then I'll wait for news from Mrs. Lu."

Seeing that Zhuge Liang did not regard this book as a sorcery, Liu Chan was also quite happy in his heart.

"In addition to this mathematics, Mrs. Lu also studies physics intensively.

She modified a trebuchet, what did the military adviser think? "

Before Liu Chan came, he took advantage of Lu Yusheng's rest time to learn about the concept of leverage principle and the simple conversion between potential energy and kinetic energy.

He was afraid that he would forget, so he recited it upside down all the way, and finally kept it firmly in his heart, so that he could show off his talent in front of Zhuge Liang.

He took a chopstick and told Zhuge Liang about the fulcrum, the point of application and the point of force in detail.

He also explained the plan in Lu Yusheng's conjecture:

Set the counterweight on the trebuchet, lift the very heavy counterweight, store human or animal power in the counterweight in the form of gravitational potential energy, and then drop it suddenly,

The gravitational potential energy stored by the counterweight is transmitted to the boulder by means of a lever,

In theory, it can produce huge lethality and cause huge damage to the city wall.

Zhuge Liang was very good at inventing and transforming facilities when he was in Gaowolongzhong. After he got the creation of Tiangong, he hurriedly researched many ordnance and agricultural tools.

He knows how to do it, but has been unable to understand the principles contained in the interaction of several things.

Under Liu Chan's explanation, he quickly understood the principle of the trebuchet, and praised:

"That's right, um,

This is potential energy, this is kinetic energy

This knowledge of understanding the power contained in all things in the world is mechanics!

This physics should be the great truth that God Haotian makes all things run in the world, right?

It's amazing, it's amazing! "

In fact, Liu Chan himself doesn't understand

However, Zhuge Liang has already understood.

He is worthy of being a military adviser, and a wise man recorded in the annals of history,

In front of him, Liu Chan felt incredibly stupid.

Zhuge Liang thought for a while, and thought that Lu Yusheng's improved trebuchet was of great value.

Should work great.

Although the Perak car has become very popular these days,

But because it is mainly pulled by manpower, and the people who are dragging can't walk in unison, naturally they can't release too large stones, and they don't fly far.

When fighting, it is necessary to push this cumbersome thing close to the city wall. If you are not careful, you will suffer heavy casualties if you are counterattacked by the soldiers in the city.

Therefore, although this thing has a long history, it has achieved certain results in Guandu, and it has not been adopted by a rush of people.
