Hearing the young man's "resentful" voice and seeing the young man's "resentful" eyes, Wang Dafu couldn't help but swallow a mouthful of spit: "This brother Tai has no ringworm of broken sleeves in the next ......"

The young man burst out laughing: "Haha, brother, I'm joking!" ”

Wang Dafu left a huge bead of sweat on his forehead: "Are you kidding? But man, your tone just now is clearly very serious! ”

"Seriously? Huh, huh? The young man said with a smile, and then said with a straight face: "Maybe, because I really envy you!" ”

Wang Dafu hurriedly waved his hand: "Don't! I don't have that hobby! ”

"I don't have that hobby either!" The young man shook his head with a smile and said, "I envy Dingchen for being so loyal to you!" ”

Glancing thoughtfully at the hunting master next to him, Wang Dafu laughed: "I'm just lucky, it's just half a step!" ”

The young man smiled and stepped forward, stretched out his right hand and said, "Thank you for helping me, it's nice to meet you, I'm the Hellfire!" ”

Wang Dafu naturally shook his hand and said, "Hehe, I've heard of the name for a long time, it's the first time we met!" ”

After greeting him, Hellfire looked at Wang Dafu seriously for a long time, and finally asked, "You...... Why do you want to help me? ”

Wang Dafu tilted his head and thought for a moment when he heard this, and then spread his hands and said very casually: "I don't know, maybe it's because I'm in a good mood!" As he spoke, he laughed, perhaps because he himself found this statement interesting.

- Just be happy! Need more reasons?

The Hellfire on the other side was stunned for a moment, and then laughed as well. Even Li Dingchen, the hunting master who was sitting next to him, laughed together without knowing it, and the sound of knowing laughter drifted far away from the window......

A few days later, Stygian left Greenwillow and returned to his own Silverpeak. He came out this time to borrow the official holiday of three months every year, but Yinfeng Town is now waiting for him to deal with a lot of things, so he can't stay outside for a long time - Wang Dafu has many special talents to help him take care of various affairs in the territory. Hellfire didn't have such good luck, and he had to do most of the things himself!

However, before the Hellfire left, the two who fell in love at first sight signed an alliance agreement, and Wang Dafu also passed this agreement to Fangniao, Chu Feixiang, and Zhang Yingzhe. Naturally, they also gained their recognition, so Wang Dafu and their small group officially added a fifth member - Yinfeng Town, Muma City of the Yuanjiang Empire!

Later, although players unanimously agreed that Wang Dafu's Greenwillow City was an outstanding representative of moderate players, Wang Dafu admitted it many times in private. In fact, the Hellfire's Yinfeng City is the true representative of the conservative faction, and at the same time, Zhang Yingzhe, who is known as the "Invincible Lucky Star", is said to have personally admitted that if his Wild Wave City fights head-on, he may not be able to fight against the "Broom Star" Hellfire Yinfeng City!

"Broom Star" Hellfire - the most mysterious of the light and dark hexagrams!

-- Length-- Phase-- -- Decision -- Determination -- Destiny -- Luck --

During the time that the Hellfire was in the town of Greenwillow. He gave Wang Dafu a lot of his own advice!

Maybe it's precisely because Yinfeng Town doesn't have too many high-level special talents, and many trivial things have to be handled by Hellfire himself. Therefore, his basic experience in territorial construction far exceeds that of Wang Dafu, and he pointed out many construction problems in Luliu Town that he did not notice, such as the water supply system, and urban sanitation, and many, many basic problems!

Xiao Rang was an excellent administrative official. However, he was born as a scholar, and he is actually not very proficient in township infrastructure. At least not as proficient as Stygian Fire! By the way, Hellfire's major in college is urban construction!

There was no professional water supply system in Luliu Town before, and the town's residents mainly relied on well water for their daily life, and Wang Dafu was not surprised by this - you can't expect tap water to appear in the era of cold weapons, right?

As a result, I didn't expect that the Hellfire Formation taught Wang Dafu a solid lesson!

"Whoever prescribes it in an ancient context

Can't you have running water? How much technology do you think the tap water system has? When he said this, Hellfire looked at Wang Dafu like he was looking at a fool!

“…… It seems that the modern tap water system seems to be one of the symbols of modern industrial civilization, right? Wang Dafu hesitated and said, although he didn't understand it very well, but he vaguely remembered that the old people seemed to be eating well water!

"That's right! The modern tap water system is indeed one of the symbols of modern industrial civilization" Hellfire nodded seriously, but immediately continued: "The problem is that there were also ancient urban tap water supply systems in ancient times!" ”

"Huh?" When Wang Dafu asked this question, the look on his face was indeed very much like a fool!

――――――――――――――――――――――

The Romans used to use the difference in water level and height to supply water to the city, which was the ancient urban water supply system, which used the spring water source in the mountains as much as possible, and then used a complex system of channels with a slope of about 1% to divert the water to the city.

The construction of aqueducts is standardized, in places with large water volumes, they are generally brick or stone channels, generally 0.3~1.5m wide, 0.6~3.0m high, and there are vents and inspection holes every 75m or so. There is an arc-shaped cover plate at the top of the canal to prevent the canal water from being polluted and to facilitate maintenance workers to work in the canal. The channels are waterproofed, and it is said that the waterproof paint made of figs, lime, and lard is used to prevent leakage. When crossing the ditch, the U-shaped inverted siphon method is used as much as possible, using lead pipes with a diameter of about 10 cm in several rows, buried in a pre-opened trench, and the water is carried from one end of the valley to the other.

After the aqueduct enters the city, the water level is maintained by an elevated elevated line, and the flow is diverted in appropriate places. Part goes into the homes of the wealthy, part into public baths, and part into public fountains, which fetch water for the public. There are automatic facilities to ensure water supply to the public. In order to ensure water supply and prevent pollution, water supply in cities is often carried through underground lead pipes.

However, the Romans did not invent the faucet, and the water supply system was open, so it was necessary to have an equally strong drainage system. This is generally solved by underground drainage channels with masonry arches.

――――――――――――――――――――――

After seeing the information in this article, Wang Dafu felt that he had indeed become a fool!

Even the ancients in the feudal era knew how to invent this simple tap water system, and they were stupid enough to watch the residents of Luliu Town drink well water every day!

Hellfire smiled and said, "Brother, I've already built this water system over there, do you want me to help you build one too!" Haha, I really didn't think that you have so many special talents here, and you didn't expect this little thing! ”

Wang Dafu patted his head when he heard this: "Okay, buddy, don't laugh at me anymore, I will come up with a plan as soon as possible!" ”

Stygian blinked: "Is it really not needed?" ”

Wang Dafu pouted: "Of course you don't need it!" ”

Stygian laughed, "Hehe, it would be better if you didn't need it......"

Looking at the smug smile of the Stygian Fire, Wang Dafu simply hated itchy, but he refused the help of the Hellfire not because of anger, in fact, the system used by the Hellfire has a fatal flaw - that is, it is easy to be cut off from the outside, which is the main reason why this water supply system was completely abandoned during the war-torn medieval period!

For Wang Dafu, he has a better choice......
