It's not that hard to open a hospital in another world, right?

Chapter 302 How to repay the female knight's debt of favor?
After speaking, there was silence in the conference room.After a while, the bishop who came to the meeting from the God of War Temple turned his head and discussed with the followers behind him, raising his hand and saying:

"We're going to see the real thing."

Gretel immediately took them down.The biogas pool is not far from the mage tower, just behind the animal breeding room. When cleaning, you can carry a bucket and flush it with water, and you can flush the excrement into the pool.The Bishop walked around the area and found that it didn't stink so much, so he nodded in satisfaction.Asked Gretel again:

"Is it convenient to boil water?"

Gretel took him next door.A hollow rattan snakes out from the ground, with an iron pipe on the top, leading directly to the stove.Gretel unscrewed the valve of the iron pipe, and randomly cast a spark spell.A flame was ignited, and after a while, boiling water began to boil in the iron pot on the stove.

"How much manure can a biogas digester process in a day? How much water can it burn?"

Gretel smiled slightly and nodded to the pastor girl who was in charge of biogas research and development.The female priest took a step forward:
"Next to our mage's tower, we built a 10 cubic meter pond, which is just enough to handle two big pigs, three small pigs, four sheep, and a pile of rabbit feces. If the biogas digester is paired with human toilets, it is estimated that 4 A cubic meter biogas digester can serve 50 to 300 people.

——50 cubic meters of biogas digesters, the biogas produced can burn two tons of water a day. "

"In summer, you can boil more water, about twice as much." Grete added next to him.The bishop lowered his head and did some calculations, and asked again:
"Can this cane be replaced by an iron pipe?"

"Of course you can!"

Gretel rushed to answer before the pastor girl.Cough, the reason for using rattan instead of iron pipes is that rattan is cheap, and the natural magic can be used to stimulate it, saving money... It was in the research and development stage before, and Gretel didn't give too much money, so everything was just used.

"Then let's get a set for the temple first. It needs 100 cubic meters - at least it can deal with horse manure and boil water by the way."

He placed the order without asking the price.With him at the beginning, the female knight Selina then stood up:

"How much fertilizer can a biogas digester produce? How much is it enough to increase production?"

“一座10立方的沼气池，一年可以产12-16吨肥料，以及50-64吨沼液。4吨肥料够一亩地用……”

This time Gretel answered a little less confidently.He estimated the annual fertilizer production and biogas slurry production; he heard about how much fertilizer was enough for one mu of land in correspondence with Elvin Elvin.As for the effect of biogas slurry on increasing production, this...

He only knows that the production will definitely increase, and he can't make up the exact amount of production increase!

However, the female knight had already smiled.After laughing, Xiumei frowned slightly and sighed:

"not enough."

"Where is it not enough?" Gretel felt a little guilty when he saw the female knight taking the lead in paying the money in the last hearing—the favor of 2000 gold coins has not yet been returned.Now seeing that the other party is too small, I hurried up to ask.The female knight stretched out her five fingers:

"One biogas digester is enough for 4 mu of land. There is one biogas digester for every thousand people in this city, and there are only 400 to 500. At best, it can cover 2000 mu of land. How can 2000 mu of land be enough!"

Gretel sweats profusely. 2000 acres of land, sister!How big a landowner are you, these fertilizers are enough for 2000 mu of land, and you still think it is not enough...

However, thinking about the two castles under his name, and the Viscounty he saw with his own eyes when he went there last time, Gretel had to admit sadly:
2000 mu of land is really nothing to a viness...

"Your Excellency Viscount, that's not the way to calculate it." Gretel had no choice but to explain to her: "The urban biogas digester I planned can burn 2 tons of water per day, with a volume of about 50 cubic meters..."

"So, the fertilizer is enough for [-] mu of land? That's about the same." The female knight nodded in satisfaction: "How much does one cost?"

"The ground part, including the water room, costs about ten gold coins, and the underground part..." Not counting.

However, if the quantity is large, there should be a discount?

Including the related divine arts of modulating the biogas tank, you should also be able to talk to the natural gods...

"That's not much." The female knight muttered softly.She then tossed her hair from the sideburns and smiled.In addition to being careless, don't be bright and moving:
"Okay, isn't it just 400 seats? I'll take it!"

"Selina!"

Beside the female knight, a young nobleman exclaimed.While making a sound, he took two steps forward, subconsciously slanting his body in front of her, as if trying to prevent the female knight from seeing Gretel.Selina squinted at him:
"Little brother, what's the matter with you? It's not expensive. I'll save two banquets and add one piece of magic jewelry, so I can save some money. These days, increasing food production is more important than anything else, don't you understand?"

While talking, he walked forward, passed the young nobleman, and walked straight to Gretel.The young noble was at a loss for words, unwilling to reconcile, and a little worried, his eyes swept back and forth between Selina and Gretel:

"I'll tell my father!"

"Yo, yo, my dear little brother." The female knight flashed her wonderful eyes and smiled softly:

"I want to tell my father, I will tell my father—I will tell my father about any trivial matter, what can you do to grow up?"

Selina turned and walked away.After confirming the plan to build 400 biogas digesters, there was nothing important about this meeting.The guests left one after another, Gretel sent out the mage tower, and gave an extra ride to the female knight.Seeing the siblings urging their horses side by side, and heading away, the female knight suddenly turned the horse's head and rushed back to him like a gust of wind:
"Master Nordmark!"

"Your Excellency the Viscount?" Gretel, who owed another debt of favor, hurriedly responded.The female knight jumped off her horse and smiled at him:
"I heard that you have recently taught several businessmen how to improve production technology. How about it? Is there any way to make a fortune with me?"

I'm not!I do not have!All the money belonged to the Department of Public Health, and none of it fell into my own pocket!

—Grete wanted to say that.However, looking at the bright smile of the female knight and thinking about the five or six thousand gold coins she spent before, there is only one answer he can give:
"Let me think about it..."

How could it be so easy to earn so much money!
Even if I have the technology, I have to consider the transformation cost and the market capacity.Besides, it's meaningless to squeeze money from one's own people, and improving productivity is the kingly way!

He frowned thoughtfully.The female knight pursed her lips and shook her palm at him:

"Okay, don't rush you. You think about it slowly, when will you figure it out, and when will you write to me—"

She got on her horse and rode away.Only Gretel was left alone, tossing and turning in the magic tower, thinking hard:
Where can I find a lucrative job?

Where can I find a technical improvement that can earn five or six thousand gold coins casually, and how can I return the favor?
"If you want me to say, it doesn't matter if you don't pay back." Aurora opened the door and came in, seeing him curled up with his head in his arms, almost getting under the table, she couldn't help laughing:
"Maybe they don't want you to pay it back at all? The more you owe, the more you owe, and then... hmm?"

"I still have to pay it back." Gretel rolled his eyes at him:
"It's not difficult to borrow and repay, but it's a mess... Let me think about it, which project should I use to repay the debt? All the good projects in hand have been sold..."

Pasteurization, salt purification, metal thermometers to control furnace temperature to assist in ironmaking... A bunch of the most valuable projects have been thrown to the Department of Public Health for investment, and the others are not so valuable!

"Is it possible to cooperate in the production of penicillin? No, absolutely not. This project is a matter of life and death, and the parliament must control it in its own hands...

Or the soon-to-be-developed smallpox vaccine?Not to mention this, things like vaccines are not for making big money! "

"You'd better think about it quickly!" Master Lin En pushed the door and came in.Mr. Troka jumped off his shoulder, holding a bronzing post in his mouth, and sent it to Gretel:
"Then, I specially invited you to their dance party! If you don't want to sell yourself, hurry up and bring out something that can redeem you!"
