It turns out that although the so-called siphon principle is a thing that was named after later generations, in fact, this thing has been widely used among the people as early as the early years of the Western Han Dynasty.

It was only at the time of the chaos that this technology gradually disappeared.

Five nonsense!

That is not inferior to the Chinese tragedy of the massacre of Mongolia in the south and the ten-day massacre of the Qing army entering Yangzhou!

"Eleven Lang is really talented, it's only been two days since I saw it, so I remade the mountain dragon again!" Shen Kuo's face was full of admiration, if this mountain dragon is used in farmland, I don't know how many Li people can benefit!

That's a great merit!

The so-called Taishang Lide, if you can really promote this mountain dragon, so far this career, it is enough to make Eleven Lang immortal!

Xin Xi laughed: "Yes, I met an old farmer yesterday, listen to what he said, there is a shortage of water this spring, and he often has to carry water up the mountain to water the ground, seeing his hard work, he thought of this thing, but ......"

"Just what?" Shen Kuo was a little puzzled, Eleven Lang's idea was really a benevolent and righteous move, what else was there to hesitate about!

"Just. You also saw it, Brother Cun, this rainbow ...... This mountain dragon can only lead the water from the high places to the low places, and it is too difficult to solve the problem of watering the ground on the hillside. Xin Zhen said deliberately: "I don't know, does Brother Cun have any good ideas?!" ”

Oh? Shen Kuo looked at Xin Zhen suspiciously, he felt that Xin Zhen was definitely changing his method to test his understanding of the use of this mountain dragon!

After a moment of deep silence, Shen Kuo spoke: "The height of the big river is about five zhang above the ground, and its water surface is high enough, as for the water surface at the low place, you can dig a deep well on the hillside!" ”

Xin Xi's face was really like this, and his heart had the same expression, but he said with sorrow: "But this tube ...... From the Yellow River to the hillside, it is about four miles, such a long pipe, and it has to be bent...... Hard! ”

"A certain family is in the bamboo business, knowing that in Bianjing, there is a Cao Zhixiu, who is running a bamboo business, find him, buy enough bamboo, find a land master, and have a land master to survey the specific water diversion route, it should not be a problem!"

A geographer, roughly equivalent to a surveyor in later generations, was a person who specialized in the layout of buildings.

Xin Zhen nodded and asked, "I don't know where that Cao Zhixiu is?!" Can Brother Cun give a recommendation, so that Xin can win a large number of bamboos at a low price! ”

Shen Kuo nodded, quickly took out a pen and paper, and said while writing a letter of recommendation: "Then Cao Zhixiu usually stayed in the store in Nanshi. His shop is on West Street near Jinshui Gate, and there are a lot of bamboos in front of the door, which can be seen by Shiyi Lang as soon as he goes! ”

After receiving the letter of recommendation written by Shen Kuo, Xin Zhen hugged his hand and said goodbye: "In this case, I won't bother Brother Cun, Brother Cun should have a good rest, I will try tomorrow, come on!" ”

"Thank you Eleven Lang!" Shen Kuo clasped his hands and saluted, and then was stunned.

Will try tomorrow?! Nima, it's almost the fourth watch now, and the fifth watch is about to dawn!

Eleven Lang, Shaft, you will try it next year, and watch Shen chat with you all night!

When I got home from Shen Kuo's place, it was already the middle of the night, and the dogs in the Zhuangzi kept barking.

When I returned to the house, I finally had a bottom in my heart about the siphon principle to divert water, and Xin Xi was also relieved.

Lying in the room, thinking carefully about the siphon principle, trying to find out if there is anything that can be improved, you must succeed once!

Just thinking about it, Xin Xi suddenly remembered that the system has been upgraded, it seems, after the system upgrade is completed, there will be one more module called the lottery, right?!

"System, is the lottery module on?!"

"It's on! But each lottery needs to consume 100,000 reputation points, does the host choose to draw?! The system's cold voice rang out.

Lottery?! 100,000 points?!

looked at his reputation of only more than 20,000 left, Xin Zhen's face was full of unhappiness: "How can Lao Tzu have 100,000?!" ”

The system was silent for a while: "The first lottery is free, and every time you go forward, you will have 100,000 points!" ”

And free?! Xin Xi was surprised, very surprised, this is equivalent to earning 100,000 prestige out of thin air!

His brain began to come alive, and Xin Zhen asked, "What's the prize drawn?!" ”

"There are three types of prizes: consumable, permanent, and functional!"

"Are they all real things? Can you get a siphon?! Xin Xi asked whimsically, if you can draw a siphon, then what kind of bamboo do you buy?!

No, no, how can you just have such a low requirement for a siphon?!

It's best to pump it straight to a pump! With that thing, do you still need to get such a painful thing as the siphon principle?!

"There are physical and virtual items, and everything that is reasonable has a probability of being drawn!"

"I'll wipe it, I'll smoke it!" Xin Zhen opened his face full of confidence, he will definitely draw what he wants, his psychology at this time, just like buying a lottery ticket, bought a note, and suddenly gave birth to the confidence that he will win the jackpot, the result is ......

"Deduct the number of free draws!"

As the cold voice of the system came, the books in Xin Xi's mind began to change the picture, turning to the last page.

This is the first time this huge book has turned to the last page, and no matter what I looked up before, it only turned to the middle.

The last page, the huge page, was twice as big as Xinxi's bed, and there were countless small boxes on it, and in the middle of the small boxes there was a blank space.

The system explained: "When the host shouts to start, all the treasure chests will roll quickly, and when the host shouts stop, the item that stays in the empty center is the prize drawn by the host!" ”

That's it!

Looking at the dense pages, there were still a lot of empty spaces, Xin Xi asked, "What if there is nothing in the blank space in the center after stopping?" Is it one more time? ”

"After stopping, the items in the empty space in the center are the host's prize, including nothing!"

Your sister!

Forget it, it's all free anyway!

After a pause, Xin Xi felt as if he had reached his lucky time, and suddenly spoke: "Start!" ”

As his words fell, countless boxes on the huge pages of paper spun rapidly at a speed beyond visual perception.

It seems that there is no possibility of cheating at all!

The so-called inseparable!

After silently counting eight seconds, Xin Xi spoke: "Stop!" ”

The high-speed treasure chest came to a sudden halt, and a dusty chest stopped in the empty space in the center!

Water pump, water pump! It has to be a water pump!

Xin Zhen muttered silently.

The black treasure chest suddenly flew out and appeared in front of Xin Zhen.

Xin Xi stared blankly at the wooden box in front of him that was about thirty centimeters long, wide and high, and was slightly stunned.

With a click, the chest opened, and a gray book landed on the bed.

Xin Zhen grabbed it with his hand, and started with the gray book: the first paragraph of Bajiquan......

Martial arts?!

What about the water pump?!

In the next second, the whole book turned into a streamer and rushed into Xin Xi's body, Xin Xi suddenly fainted, and some inexplicable pictures began to appear in his mind.
