The plasterer came soon. The town was originally small. The middle-aged woman found the plasterer in just a few minutes. Just like the blacksmith just now, she was also a simple and honest middle-aged man. Bai, immediately put on a respectful look: "Buy Faren, I heard that you are looking for a plasterer, I am happy to help you."

Robb didn't mean anything, and said directly: "I need you to cut off the roof of my church and build a cistern on it."

"Hey?" The plasterer was startled: "Faren, this is not okay. Build a reservoir on the roof, top-heavy, the house is easy to fall, and it is also easy to leak water, and the house will feel like it is raining."

Robb thought about it carefully, and that's right, the level of construction this year hasn't reached the level of a rooftop cistern.

"Let's do it then." Robb said: "Beside the church, a small stone tower was built on the open ground next to the well, and then a reservoir was built on the top of the tower."

"I can do this." The plasterer hurriedly saluted: "But this requires a little more manpower, and it takes a lot of rocks to move it. I don't have enough power alone."

This kind of artificial thing is quite troublesome for ordinary people, but for the rich, it is a trivial matter. Robb suddenly thought: I used to take tasks in games, and I was commanded by NPCs. It's almost time for Feng Shui to take turns now.

OK, release a constructive task.

He took out two gold coins and said with a smile: "Well, now I give you a task, that is to help me build a small stone tower as high as a roof, and build a big reservoir on it. These two gold coins are Remuneration, you find a way to hire labor, but I don’t care about it.”

The plasterer is overjoyed. The labor in this broken town can be worth a few dollars. It doesn’t take dozens of silver coins to invite a lot of people to line up to carry the stones, and then deduct the cost of materials. You can earn at least one gold coin after completing this task yourself. .

He happily said: "Buy Faren, please leave this to me."

The plasterer used all the compliments he knew to praise Robb, and then left happily.

Three days later!

Next to the well, a wide and thick stone tower was erected. Since the top of the tower needs to be built with a reservoir, the stone tower cannot be built to be very small. It must be built to have a big waist. The bottom is solid with stones. The middle is not hollowed out like an ordinary "tower", but it is all filled with stones. It is not so much a stone tower as it is a stone mountain.

Twenty townspeople were dispatched to build this stone mountain. They kept carrying stones from the rocky **** on the side of the mountain, and under the command of the plasterer for three days, the gap between the stone and the stone was used. Kind of strange mud to stick. And each of them was paid only three silver coins, just like that, they were already very happy.

The plasterer pasted layer after layer of waterproof material in the top pool. Honestly speaking, Robb really didn't understand how people in this era prevent water from leaking. He also made this kind of strange material. I don’t know, but it doesn’t matter.

"Buy Farren!" The plasterer gave Robb a big gift: "Now it is ready. Just wait for it to dry, and you can store water in it. If it rains before it dries, I will rush to it immediately. Cover it with oilcloth."

Robb said: "Very well, these two gold coins are yours."

The plasterer took the money: "Thank you God of Light, thank you for buying Farren."

Thank God again? Well, you are not kind, and I am not righteous anymore.

Robb put on a glorious appearance: "Oh, my child, the God of Light will remember your dedication to the church."

This is called treating one’s body by the way of others. Since you like to thank the God of Light so much, then I will let the God of Light remember your dedication. As for me, of course don’t remember it, I To be a feudal landlord with no emotions, hum!

After the plasterer collected the money, he looked curiously at the stone tower towering high by the well: "Buy Faren, what are you doing? Although I helped you make this thing, I think this thing is nothing. It's not practical. Why build the reservoir on such a high place? How can it be used to store water like this? Is it necessary to build a ladder to climb up every time I need to use water?"

Robb smiled and said, "Well, don't worry! There will be an answer soon."

At this point, the blacksmith came, and he also brought many iron pipes of different lengths, and several taps.

As soon as he saw Robb, he immediately saluted him respectfully, first greeting the God of Light, and then greeting his father: "Buy Faren, I fixed the iron pipe and the faucet according to your request, and got your instruction. After the process, I quickly made the iron pipe, but the faucet was really too difficult and it took a lot of time."

"Well, it's okay, it's understandable to spend some time." Robb smiled and said to the plasterer: "You help the blacksmith and install these iron pipes in the deepest part of the reservoir."

The blacksmith actually didn't know what he was doing now, but when the plasterer saw the iron pipes, he looked up at the cistern built on the heights, and suddenly understood. After all, he is a profession that often deals with mud and water, and the truth of the water flowing down is better than anyone else.

"Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!

The plasterer felt as if he had learned something.

However, he quickly sat down on the ground and said annoyedly: "No! Although it seems to be easier to get water, but if it doesn't rain, there will be no water in the pool, and this pool won't be used at all. , And even if the water is full in the next heavy rain, it will be used up as long as it does not rain for a few days. Although the idea of ​​adding iron pipes to this high-level reservoir is great, it is actually not very practical."

Robb patted the plasterer on the shoulder and smiled, "Do you know Archimedes?"

"I know!" The plasterer nodded fiercely: "The most famous ancient great wizard Archimedes, no one on this continent doesn't know."

Robach said: "Great Sorcerer? Ahem!"

Well, it seems that Archimedes is also in this world, but he is no longer an ordinary mathematician, but a great magician. Forget it, that's not the point! Let’s talk about business first, Robb said: "Archimedes has solved the pumping problem long ago. Its name is Archimedes Water Spiral."
