Even as a science student, Gu Lan said that he was not interested.

If it weren't for the exam in the previous life, this life would be rewarded by the system... I would never have anything to do with this kind of agricultural classics!

"Xianggong, you're back." Mu Yuyan came back to his senses from the book, looked up at Gu Lan with a delicate little face, and muttered: "Today, I was sweeping the study for Xianggong, and I accidentally dropped this book, and when I saw some strange pictures drawn in it, I couldn't help but pick it up and look at it for a while...

Can you read this book as a concubine? ”

Her smart eyes twinked, and she asked with her red lips pursed.

It seems that he is afraid that this book will touch Gu Lan's privacy.

"Absolutely." Gu Lan rubbed her black hair dotingly, and said with a gentle smile: "It's written for people to see, if you don't understand, you can come and ask me." ”

When it comes to the classics of my previous life, I still have something, although there are not many things...

"Thank you."

Mu Yuyan thought for a moment, turned to a page of drawings from the book, and asked in a shallow voice: "Can Xianggong tell me what this "big wheel" is?" ”

Gu Lan looked down.

It turned out that the drawing was a model of a waterwheel that I had nothing to do.

He was also quoted as a marker next to it: "The height of the ground is drawn by a water wheel, and irrigation is very convenient." ”

"It's called a waterwheel, or a tube truck, and it's an irrigation tool built on a river."

Gu Lan described: "It can use the flow of water, save manpower, and direct the river water to the fields. ”

"Save manpower? Is it a kind of immortal method? ”

Mu Yuyan asked confusedly.

She didn't know what it meant to use the current.

But there is indeed an immortal method in this world that can move mountains and reclaim the sea.

However, when the monks reach this level, they will definitely not use their immortal methods for such trivial things as irrigation of farmland.

"It's not an immortal law, ordinary people can do it."

Gu Lan shook his head and smiled, patiently explaining.

"The waterwheel is fixed to the river, and the river pushes forward, driving the wheel of water to turn, and on the wheel there are some wooden cylinders fixed to it, which can fill it with water at a low place, bring it to a high place, and flow down the wooden trough to the distant fields..."

Gu Lan pointed to the waterwheel on the drawing, wrote and painted, and gave a decent lecture.

Mu Yuyan leaned over and leaned on Gu Lan's shoulder to listen carefully, her pretty face was full of curiosity, like a white-skinned and beautiful school girl in her previous life.

Moment.

Before Gu Lan finished explaining the principle of kinetic energy and potential energy, Mu Yuyan suddenly realized.

With her IQ, as long as she speaks it once, it is naturally effortless to understand simple farm tools.

It's just that such a novel tool is something she has never heard of or seen!

"Xianggong, how did you come up with such an ingenious tool?!" Mu Yuyan was very surprised, and stared at Gu Lan with interest.

This mysterious and charming man... There are always surprises.

"It's... Isn't it ingenious? ”

Gu Lan raised his eyebrows and asked rhetorically.

Mu Yuyan: "??? ”

"It allows mortals to cross the gap between immortals and mortals, and do things that ordinary monks can't... Isn't that clever enough? ”

Mu Yuyan's beautiful eyes were surprised.

In her opinion, this kind of tool is simply ingenious, after all, there has never been a mortal artifact in the world that can replace the immortal method!

But Gu Lan's eyes looked extremely flat, and the empress was not confident at all!

It seems that the immortal law of the fantasy world has stifled the development of scientific and technological civilization to a certain extent... Gu Lan said that the 5,000-year-old labor wisdom of my hometown is just the most primitive.

"Come, lady, look at these pictures, and you will understand that the farm tool is not enough."

Gu Lan chuckled, walked to the table, and took out a stack of drawing paper, which was full of interesting things that he usually had idle and boring, recalling his previous life.

"Xianggong, this is a painting... Trees, bugs, and fish ponds? ”

Mu Yu Yanyu pointed to his lips, and his watery eyes revealed incomprehension.

She didn't understand the purpose of putting these three things together.

Then.

Gu Lan took the pen and spent three arrows on the paper, so that the three formed a closed loop.

"Lady, look, this leaf can feed insects, insect sand or insect chrysalis can feed fish, and fish mud can be turned into fertilizer to nourish trees, and the three depend on each other..."

Gu Lan told carefully.

In fact, this thing has a very simple name - Sankey Fish Pond!

As long as you have studied junior high school biology, you will know.

With a special breeding model, to maximize the benefits... This is much more advanced than just a tool.

After listening to the explanation, Mu Yuyan gradually understood the mystery!

From the time Gu Lan drew the arrow, her expression was slightly enlightened, and after listening to a few words, her beautiful eyes widened directly, and there seemed to be such a wonderful blueprint in front of her!

I actually thought of letting the three supply each other and harvest at the same time, this model can really be... Mu Yuyan unconsciously covered her mouth.

However, that's not all!

Mu Yuyan hadn't finished digesting the shock at the moment, and the following pictures came into view, which made her even more overwhelmed!

"This is a wooden ox and flowing horse, which can save people from carrying goods on their shoulders and hands; It's called a vernier caliper, which can eliminate the error of the naked eye, and measure to the millimeter..."

"This is a windmill, it's still not the same as a waterwheel..."

"Ahem, that... It's called a mobile phone, but it's not a chicken, it's a communication game device, and it should be very difficult to make it now..."

Gu Lan talked eloquently, like a few treasures.

Mu Yuyan was numb!

The product of wisdom that has never been seen before, a wave of unsettled and wave after wave of trembling of the heart!

makes her feel that in the past 20 years of being in charge of the world, it seems that she is sitting in a well and watching the sky!

It's not about cultivation.

It's just that the proud and intelligent empress is convinced when she feels that her IQ and knowledge are being crushed!

Half a day.

After Gu Lan finished speaking, Mu Yuyan hurriedly handed over a cup of hot tea.

The beautiful little face is shocked and full of worship!

"Xianggong, these... How did you come up with the idea?! ”

As far as Mu Yuyan is concerned, what he heard in just half an hour is too unbelievable.

She never thought that Gu Lan's small bookstore would contain a vast amount of knowledge that no wise man in the world had ever touched!

Compared with Gu Lan, those people in the Ministry of Industry of the Imperial Court are wine bags and rice bags are all lifting them!

Facing the admiration of the lady who is about to overflow.

Gu Lan waved his hand lightly and said with a gentle smile: "Looking up at the vastness of the universe and looking down at the prosperity of categories, if the lady is interested, I will draw them in the future and take a closer look with you." ”

Looking at Mu Yuyan's rippling peach blossom eyes, Gu Lan felt that Gou's life in Langzhou was suddenly not so boring.

In my previous life, I told the girl that I would be annoyed with knowledge, but I could pretend to be a good beep in front of the lady.

Who can withstand this?

Gu Lan's heart was full of joy, far from being as light as it appeared on the surface.

At this time, the sound of Lao Yang Tou and Xiao Xi having dinner came.

The two sorted out the books and paper, and walked out of the study hand in hand by moonlight.

At the same time, a mechanical voice sounded in Gu Lan's mind.
