"Tiangong Kaiwu" was first published in the tenth year of Chongzhen of the Ming Dynasty, and was called the encyclopedia of Chinese craftsmanship in the seventeenth century by foreign academic circles, and the whole book is divided into three volumes, a total of 123 volumes.

"Covering people to create foreign objects" is the essence of the manual and mechanical chapter of the classics.

A lot of physics knowledge such as mechanics and heat is used in melting, lost-wax casting, windmill design, etc. In terms of technology, we pay attention to "difference" and "ingenuity".

After breakfast, when Ou Zhou was flipping through this ancient book, he accidentally noticed a few features between the lines: in the three volumes of machinery manufacturing, smelting, and water conservancy, every few pages, there are annotations from readers.

One of the sentences is: Although human skills are skillful, there is no one more skillful than nature.

He pondered the meaning of this sentence over and over again, meaning that the human brain is not as ingenious as the power of nature.

"I see?" Ou Zhou patted the back of his head and smiled, "No wonder we searched the room all over the place, and we couldn't find any clues." It turned out that the door to the vault was not in the room at all. ”

Ke Feier smiled and asked, "Tell me, where is the door to the vault?" ”

"Look at this commentary, although the skill of man is skillful, there is no one more skillful than the skillful man of nature."

"What does that mean?" Shui Jingxin asked.

"It shows that the entrance to the vault was not designed by human beings at all, but by the power of nature."

"Force of Nature, which part of this manor is designed to take advantage of the Power of Nature?"

"We might as well count the forces of nature, wind, water, tides, light, thunder, and earthquakes. You can think about it, in the whole manor, which piece of structural design meets the characteristics of several forces and energies? ”

"This may seem complicated, but we can use the elimination method to filter it," said Kirfiel, "and of the several forces and potential energy, earthquake is the most destructive and the most difficult to control, so it is not practical." Tidal forces are exclusive to the sea, and this condition is not available here. Thunder and lightning are too affected by weather changes to be difficult to navigate, and they can also be ruled out. Light energy is currently only used to generate electricity and extract heat. The potential energy generated by electricity is within the scope of human skills and can also be excluded. Wind power is subject to climate change, and it comes and goes, and people can't use it if they want to. Only water conservancy can be recycled indefinitely. The waterwheel irrigation device of the Three Kingdoms period and the water-pressed rice technology of the Eastern Jin Dynasty all used the natural power of water energy. ”

"Sister, this manor is surrounded by mountains and rivers, and the use of water can have innate advantages, but in the entire manor, I don't see which piece is designed to use water power?"

"Yes, beautiful sister, this house is in the belly of the mountain, the garden is halfway up the mountainside, and it seems that I have never seen the potential energy of the water?"

"Could it be that it's not using the potential of water, it's wind energy, or light energy?" Ou Yiran wondered.

"On a windless day, wind energy cannot be used. Similarly, if it rains on a cloudy day, you can't see the sun and you can't use your light energy. It does not meet the convenience of opening and closing the vault at any time. Jiang Yang analyzed.

"It's also a ha, the eighth layer of the cave exploration micro-heart method can't be found, and there is no water potential available in the manor, what the hell is going on?"

"Could it be that there is no treasury in this manor at all?" Shui Jingxin said.

"The construction of a secret vault in such a scenic area is very much in line with the idea that people do the opposite. Moreover, several altar owners know that there is a vault in the manor, which should not be groundless. Ke Feier analyzed.

"Forget it, my brain hurts when I think about it. Tomorrow will be the Chinese New Year's Eve, let's still think about how to spend this Spring Festival, right? Yun Lei said.

"Anyway, the Tao is natural, everything follows fate. It's ours, sooner or later you can find the vault, it's not ours, you just want to break the sky, it's in vain. Ou Yiran joked.

"Auntie, in my opinion, we won't be going anywhere this Spring Festival, let's spend it here." Water meditation is recommended.

"Yes, Sister Yun, it is a five-star hotel in the city, and it is not as luxurious and beautiful as the environment here!" Xia Zining added fuel to the fire.

"It's also a good place, count and count, it's really good here. Then we will spend the Spring Festival here, and there is nothing missing anyway. Yun Lei smiled.

"Mom, how can there be no shortage of it, in my opinion, there is a lack of a chef!" Ou Zhou said with a smile.

These words reminded Yun Lei: "This is indeed a bit strange, you say, why is there no chef here, can't the three helmsmen cook by themselves?" ”

"Perhaps, the three helmsmen don't dine here at all." Ou Zhou said.

"What's strange, there are enough fresh ingredients in the kitchen, and a complete set of kitchen utensils, if you don't cook or cook, is it for seeing?" Shui Jingxin said.

"It's a bit of an evil door, not only the kitchen, but even the whole living room, it seems to be used for appearance." Ke Feier said.

"Yes, three people, each enjoying a large living room of 200 square meters alone, in any way, it is very unreasonable!" Ou also said.

"Furnishings are usually for people to see, is it all an illusion, and there is something else inside?" Ke Feier wondered.

"The so-called three holes of the cunning rabbit, this is one hole, what if there are two other caves for the head of the flying car bandit?" Ou Zhou is like an initiation.

"I said, you all save it, let the brain cells rest and rest, and have a good New Year, which is stronger than anything else." Yun Lei once again spoiled the scenery.

Everyone looked at each other and smiled, and Ke Fei'er said: "Okay, listen to Mother Yun, we all don't think about anything today, let's concentrate on arranging the New Year!" ”

So everyone worked together and arranged for Jincheng and Liao Yunhui to purchase rich festival necessities outside, and for seven days, they lived in the villa to enjoy the beautiful scenery and food.

At noon on the seventh day of the Lunar New Year, everyone was about to enjoy a sumptuous lunch.

Suddenly, the alarm bell rang out in the villa.

The faces of the seven people changed instantly, and Ou Zhou, Jiang Yang, and Ke Fei'er immediately realized that what was supposed to come was finally here.

"Daddy Ou, Mother Yun, Aunt Zining, don't go out here, let's go and see, which way of the immortal can make such a big move?" Kefeier said.

Ou Yiran and Yun Lei glanced at each other and instructed: "Those who come are not good, you must be careful." ”

The three teenagers hurried to the helmsman's chamber. Shui Jingxin was unwilling to be lonely, and also went together.

At that time, Jin Cheng and Liao Yunhui, the chief and deputy helmsmen of the Promotion Association, were already waiting in the hall.

"Two helmsmen, what's the situation?" Koffel asked.

"Three people came from outside the villa, and they said they wanted to challenge us. The two of us felt that things were not simple, so we warned a few young heroes and asked for instructions on what to do! Jin Cheng said.

"Do you know where it came from?" Ou Zhou asked.

"I don't know, but look," Jin Cheng said, pointing to the big screen, "judging by their clothing and body shape, they should be Japanese people." ”

Ke Fei'er nodded and said, "That's it, two younger brothers, you still pretend to be the two helmsmen, and go out to learn their skills." As I expected, they must have come from the Wa Gang to seek revenge. ”

Ou Zhou and Jiang Yang have been nesting in the villa for these days, and they are about to move their skills, and when they hear the words, they are overjoyed and immediately begin to change their appearance.

Jin Cheng and Liao Yunhui looked at them in astonishment, and in front of the deity, in the blink of an eye, they changed into their own appearance.

At this moment, four people with the same appearance and different mannerisms smiled heartily. The false helmsman went to meet the guests outside the manor.

And the real helmsman and Ke Feier Shui meditated, sitting in front of the big screen to enjoy the wonderful pictures that are about to appear.

Ou Zhou and Jiang Yang Shi brothers went out of the gate and came to the three widows.

Jiang Yang asked in a deep voice: "We are the new chief and deputy helmsman of the chief helmsman, I don't know if the three of us have come here, what advice do you have?" ”

A stocky man with an age of about fifty stepped forward, and said with a calm expression: "I heard that you two killed three helmsmen in one move?" ”

"Yes, do you have any advice, please say it directly?" Ou Zhou said.

"Originally, it was more than enough to sit in the position of the chief helmsman with your efforts, but there is a sequence of things, and there is a superiority, you have committed the following crimes, killed the former helmsman, usurped the important affairs of the gang, and have committed the heinous crime, and today I am waiting to come here to seek justice for the three helmsmen." The man said.

Jiang Yang rebuked in a deep voice: "Do you know how brutal the previous helmsman was, if the two of us hadn't killed by force that day, we would have become dead souls long ago." I want to ask you, as the chief helmsman, why do you regard the lives of your subordinates as grass mustard, kill whoever you want, take whomever you want, take whomever you want, the life of the helmsman is life, and the life of the altar master is not life? ”

The man said: "As I just said, there are high and low things, and there are high and low, and the helmsman is your boss, and as a boss, he has a desire to kill and punish his subordinates to seize power." Otherwise, how to deter subordinates and leaders? ”

Jiang Yang said again: "There is one more question, please tell me?" ”

"Is it okay to be straight?" The man's demeanor was neither humble nor arrogant, and there was no trace of emotional orientation in his tone.

"As far as I know, the backstage of the biker party is the Japanese people, you three, were you sent by the Japanese people?"

"Eight grids!" A fierce-looking man behind him stepped forward and shouted.

The man's demeanor was the same as always, he waved his hand and retreated with a ruthless manly hum.

"You're right, we did come from over there."

"Thank you for being able to speak up."

"No thanks, the reason why I told you is because I don't want you to be a fool."

Jiang Yang and Ou Zhou looked at each other in astonishment, turned around and smiled: "You are so confident, you have the ability to kill us?" ”

The ruthless man took a step forward and said, "Don't be rude, this is the president of our LaCrosse and the number one master of the Great Wa Kingdom." ”

"Yes," Jiang Yang waved his hand, calmly flicking off a flying insect, and the insect snapped on the tip of the ruthless man's nose, "I'm really sorry, I blame this insect for being too eye-catching." He smiled lightly.

The ruthless man wiped it off, and after taking a look, he couldn't help but be furious, and he was about to rush up to theorize.

As soon as the man stretched out his hand to stop him, he couldn't help but be shocked in his heart, the flying insect was close, and it was difficult to bounce it down with his own skills, but if it accurately bounced on the tip of someone else's nose ten meters away, he thought that he couldn't do it.

He couldn't help but feel a deep fear of this trip. He didn't know how powerful the kung fu of the three helmsmen was. But the young man in front of him swayed freely, and the stunt of lifting a weight with one hand like a flying insect with a flick, made him feel awe. As for the other party's use of insects as a metaphor for a ruthless man, he just didn't hear it.

But the man still said calmly: "Since this is the case, let's see the high and low in our hands!" ”
