Into Unscientific

During the previous 1665 dungeon settlement process, Xu Yun made one thing clear:

The higher the score, the better the reward you will get.

So for Xu Yun.

In order to obtain the highest score possible, Bianjing’s priority is obviously higher than that of Jingkou.

After all, this is the political and economic center of the entire Song Dynasty. The social environment is much more complicated than Jingkou, and it is also easier to cause trouble.

Moreover, from the perspective of medical level, although the current medical level of Song Dynasty is still in the stage of ancient medicine, the medical reserve of Bianjing is obviously better than that of Jingkou.

Once Old Suzhen had an accident such as a fall, maybe the well-known doctors in Bianjing could rush to the scene as soon as possible to minimize his injuries and try to avoid the early death of such a great master.

Therefore, based on the above considerations, Xu Yun must keep Lao Su in Bianjing.

But still that sentence——

Where is the entry point?

This is clearly not a problem for which a solution can be easily devised.

However, due to the sufficient time for the task, Xu Yun was not in a hurry, after all, it was only the first day.

He put aside the point of entry for the time being, and chatted with Xiao San'er with the intention of inquiring information and chatting:

"Third brother, how old are you this year?"

Xiao San'er was tying a rope at first, when he heard this, he subconsciously touched the scarf, and tucked the corners of the unbound hair:

"Seventeen this year."

Xu Yun nodded slowly.

If I remember correctly, the adult age of a man in the Northern Song Dynasty should be twenty years old:

"Then what's your full name? Is it just Xiao San'er?"

Little San'er shook his head:

"That's not true, my name is Zhang San, and I am the third in the family, so everyone calls me Xiao San'er.

Just like your Wang Mazi, a cheap name is easy to support. "

"So that's it. By the way, who was the old man who was the leader yesterday?"

"Old man? Oh, you mean the old man is in charge. His name is Xie Yuannian, and he is also the chief steward of the entire mansion. How much money we get every day to buy vegetables and goods has to be approved by him."

"Then what about the guy from before?"

Xu Yun guided him intentionally or unintentionally in this way, and after half an hour, he basically sorted out the relationship between Su's family:

Besides Lao Su, the 'Second Master' in the mansion is Lao Su's fourth son, Su Mao, who is also the only son of Lao Su who stays in Bianjing.

As for the servants, Xie Yuannian was the chief steward in charge of personnel and finance in the mansion, and next to him was a maid named Yue Lian.

The leader of the nursing home is a man named Zheng Kuan, who is rumored to have served in the Western Army and has superb martial arts skills.

Su Mao, Xie Yuannian, Yue Lian, Zheng Kuan.

This is F4 in the whole mansion except Lao Su's family.

During the period, Xiao San'er also asked about Xu Yun's information, but it seemed that out of a certain "protective" mentality, Xiao San'er didn't ask much about Xu Yun's past.

that's all.

Two quarters of an hour flew by.

Two quarters of an hour later.

In front of Xu Yun and Xiao San'er there were no more than twenty wooden barrels. Seeing that all the barrels were filled with water, Xu Yun quickly picked up one of them and said to Xiao San'er:

"Third brother, shall we set off now?"

Xiao San'er was humming a song, but when she heard this, she looked at him in surprise, and asked:

"Where are you going?"

"."

Xu Yun couldn't help raising a black line on his forehead, and asked:

"Didn't you say to send water to the main room?"

The expression on Xiao San'er's face was even more surprised:

"It is to send water to the main house, but there is no need to carry a bucket."

Xu Yun:

"????"

Seeing Xu Yun's bewildered face, Xiao San'er waved his hand:

"Ham, it's troublesome to talk about, you'll find out later, put the barrel down first."

Seeing this, Xu Yun had no choice but to put down the wooden barrel, followed Xiao San'er to find a seat by the well for some unknown reason, and waited with a trace of curiosity.

After half a quarter of an hour.

At the entrance of the courtyard where the well was located, a figure of a young woman appeared.

The visitor's hair is in a bun, tied with a blue ribbon, the hair is soft and smooth, and is draped over the shoulders obediently.

Wearing a light green long dress with light blue peonies embroidered on the cuffs, a few auspicious clouds drawn out with silver threads, and a small round face against the delicate features, which looks quite flattering.

Seeing this person appear, Xiao San'er quickly got up with Xu Yun:

"Hello, Miss Yuelian."

Xu Yun also lowered his head slightly, and a flash of clarity flashed in his heart:

Yue Lian, it seems that this is the big maid in the F4 group.

Yuelian heard the words, and smiled at Xiaosan'er very familiarly:

"Hello, third brother, you look good today. It seems that yesterday's cuju must have won?"

Xiao San'er scratched his head hehe, a little embarrassed and said:

"Haifeng Xuegong lost three goals first, and chased them all back within a quarter of an hour before thinking about it. They won a big victory when they hit the point. They were lucky enough to make fifty or seventy cash, and they were able to buy an extra pork knuckle to eat."

Yue Lian nodded while laughing, her gaze swept over Xu Yun curiously.

Then he didn't know what to think of, and a trace of pity flashed in his eyes.

Xu Yun: "????"

Why is everyone looking at me like this?

Afterwards, Yue Lian's expression straightened, and she said to Xiao San'er:

"Okay, third brother, the business is important, let's start now."

"Decree!"

Xiao San'er was still smiling, and familiarly took out a small tombstone cough, a small wooden cup from his body.

Then he walked to the wooden barrel that had been beaten, scooped up a small cup one by one, and drank all of it into his mouth. (Paper 10.15986/j.1008-7192.2020.02.003 is attached to the anti-bar, the study of the urban space of Tokyo (Bianliang) in the Northern Song Dynasty from the perspective of daily life, which talks about the drinking habits of the rich and powerful, and the servants who need to fetch water to test the water non-toxic for delivery)

After Xiao San'er had tried all twenty buckets of water, Yuelian just nodded.

Walking to a stone pillar at the corner of the wall, he took out a key.

It was only then that Xu Yun noticed that there were three cuboid stone pillars standing at the corner of the courtyard, about half a meter in height and 30 centimeters in side length.

In the left middle of each stone pillar, there is a keyhole.

Then Yue Lian inserted the key into it and twisted it lightly.

The top of the stone pillar lifted slightly like the lid of a rice cooker, opening the hollow pipe inside.

Then Xiao San'er winked at Xu Yun:

"Wang Mazi, don't talk too much, just pour some water."

As he spoke, he picked up a bucket of water, went to the side of the stone pillar and poured it in.

Xu Yun was stunned for two seconds, and quickly followed suit.

Xiao San'er's bucket of water was quickly emptied, and Xu Yun took over immediately, with a very positive attitude.

However, although the movements of his hands were swift, there was still a doubt in his heart:

It is clear.

The pipe of this stone pillar should lead to a certain reservoir, so as to save the trouble of manpower carrying buckets.

But the problem is that it is easy to pour water. How does this water flow to the reservoir?

Xu Yun's three-dimensional sense is very keen, he can be sure that the deepest part of the stone pillar is the ground, a standard L-shape.

That is to say, there is no situation where the bottom of the stone pillar is higher than the ground, and the pipe uses the height difference to transport the water source—in fact, this method is not very feasible, because the straight-line distance between the well and the main house may be nearly a hundred meters, tens of centimeters If the slope of the height wants to be extended to this distance, the cost is enough to send water by manpower for decades.

The same is true for drilling holes obliquely:

Under the background of this age, it is not too difficult to open a parallel pipeline in the shallow layer, but the cost of drilling a hole obliquely is high.

But if the stone pillar pipe is parallel to the ground, how does the other end get water?

A parallel pipe that is a full hundred meters long, even if all 20 barrels of water are poured down, the flow that can be received at the other end is destined to not be too much.

The principle of pumping wells is possible, but the 100-meter pipeline relies on the principle of one-way valves of pumping wells.

Again, the cost is greater than that of simply delivering water by manpower.

unless

It has something special inside it that makes it possible to bring water to the main room continuously and without much effort under parallel conditions
