Chapter 302 How to Repay the Female Knight’s Debt of Gratitude?

After finishing the conversation, there was silence in the conference room. For a moment, the bishop who came to the meeting from the Temple of the God of War turned his head to discuss a few words with the attendants behind him, raised his hand and said:

"We want to see the real thing."

Grete took them down immediately. The biogas pool is not far from the mage tower, just behind the animal breeding room. When cleaning, you can flush the excrement into the pool with a bucket. The Lord Bishop walked around and found that it didn't stink very much, so he nodded with satisfaction. Asked Grete 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 top, leading directly to the stove. Grete unscrewed the iron pipe valve and cast a spark spell. A flame burst into flames, and soon the boiling water began to gurgling in the iron pot on the stove.

"How much excrement can be processed in a biogas digester in a day? How much water can it be boiled?"

Gretel smiled slightly and nodded to the priest girl in charge of biogas research and development. The female priest took a step forward:

"Next to our mage tower, we built a 10-cubic-meter pool. Currently, it is enough to process the feces of two big pigs, three little pigs, four sheep, and a pile of rabbits. If the biogas pool is equipped with a human toilet, it is estimated that 50 A cubic meter biogas pool can be used by 300 to 500 people.

——A 50 cubic meter biogas pool can produce two tons of water a day. "

"In summer, you can boil more water, probably twice as much." Grete added next to him. The bishop lowered his head and did some mental calculations, then asked:

"Can this rattan be replaced with an iron pipe?"

"Of course!"

Gretel rushed to answer before the priest girl. Well, the reason why rattan is used instead of iron pipes is that rattan is cheap and can be stimulated by natural magic, which saves money... It was in the research and development stage before, and Gretel didn't give much funding, so everything was used as it was.

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

He placed the order without asking the price. As he started, the female knight Selina followed and stood up:

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

"A 10 cubic meter biogas digester can produce 12-16 tons of fertilizer and 50-64 tons of biogas liquid a year. 4 tons of fertilizer is enough for one acre of land..."

This time, Grete answered a little less confidently. He estimated the annual amount of fertilizer and biogas slurry produced; he heard about how much fertilizer is enough for one acre of land through correspondence with Elder Erwin. As for the effect of biogas slurry on increasing production, this...

All he knows is that production can definitely be increased, and he can’t make up the exact amount!

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

"not enough."

"What's not enough?" Ever since the female knight took the lead in paying the money during the last hearing, Grete felt a little guilty when he saw her - without him, the favor of 2,000 gold coins has not been paid back yet. Now that I saw that the other party was too little, I quickly went up to ask. The female knight stretched out her fingers:

"One biogas digester is enough for 4 acres of land. There is one biogas digester for every 1,000 people in this city, so there are only 400 to 500 biogas digesters. At best, it can be used for 2,000 acres of land. How can 2,000 acres of land be enough!"

Gretel sweated. 2,000 acres of land, sister! How big of a landowner are you? These fertilizers are enough for 2,000 acres of land, but you still think it’s not enough...

However, thinking about the two castles under his name and the viscounty he saw with his own eyes the last time he went there, Grete had to admit sadly:

2,000 acres of land is really nothing to a lady...

"Your Excellency, this is not how it is calculated." Gretel had to explain to her: "The urban biogas digester I planned can burn 2 tons of water every day, and it will have a volume of about 50 cubic meters..."

"So, the fertilizer is enough for 10,000 acres of land? That's about the same." The female knight nodded with satisfaction: "How much does it cost to build one?"

"The above-ground part, including the water room, costs about ten gold coins. The underground part..." I haven't counted yet.

However, there should be discounts if the quantity is large?

Including the magic related to modulating biogas pools, you should also be able to talk to the Natural God Cult...

"That's not much." The female knight muttered softly. She then flicked her hair around her temples, raised her face and smiled. Apart from being careless, there is something bright and touching:

"Okay, isn't it just 400 seats? I'll cover it!"

"Salina!"

Next to the female knight, a young nobleman exclaimed. While making a sound, he took two steps forward and subconsciously moved his body in front of her, as if to prevent the female knight from seeing Gretel. Selina glanced at him sideways:

"Brother, what's wrong with you? It's not expensive. I have to hold two less banquets and buy one less piece of magic jewelry. This money will be saved. These days, increasing food production is more important than anything else, don't you understand?"

As he spoke, he walked forward, past the young noble, and walked straight to Gretel. The young noble was speechless, unwilling and a little worried. His eyes flicked between Salina and Gretel:

"I'll tell dad!"

"Yo, yo, my dear little brother." The female knight's eyes flashed and she laughed loudly:

"I'm going to tell my father, I'm going to tell my father - I'm going to tell my father about any trivial matter, when will you grow up?"

Selina turned and left. After the plan to build 400 biogas digesters was determined, there was nothing important in this meeting. The guests took their leave one after another, and Grete sent the mage tower out, giving the female knight an extra ride. Seeing the two siblings riding their horses side by side and galloping away, the female knight suddenly turned her horse's head and ran back to him like a gust of wind:

"Mage Nordmark!"

"Your Majesty the Viscount?" Gretel, who owed another debt of gratitude, quickly responded. The female knight jumped off the 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 you can make a fortune with me?"

I'm not! I don't! All this money belongs to the Department of Public Health, and not a penny has gone into my own pocket!

——Gretel wanted to say this. However, looking at the bright smile of the female knight and thinking about the five or six thousand gold coins she had spent before, there was only one answer he could give:

"Let me think about it..."

How can it be so easy to make so much money from a business?

Even if I have the technology, I still have to consider the cost of transformation and the market capacity. Besides, there is no point in squeezing money from your own people. Improving productivity is the way to go!

He frowned in thought. The female knight pursed her lips and waved her palm towards him:

"Okay, I won't rush 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. Gretel was left alone, tossing and turning in the magic tower, thinking hard:

Where can I find a job to make money?

Where can I find a technical improvement that can easily earn five or six thousand gold coins, and how can I return the favor?

"If you ask me, it doesn't matter if you don't pay it back." Aurora opened the door and came in. Seeing him curling up into a ball with his head in his hands, barely hiding under the table, Aurora couldn't help laughing:

"Perhaps they don't want you to pay back at all? The debt keeps getting bigger and bigger, and the debt keeps getting bigger and bigger, and then... hmm?"

"I will definitely pay it back." Gretel rolled her eyes at him:

"It's easy to borrow again, but it's a mess... Let me think about it, which project should I use to pay off the debt? All the good projects I have have been sold..."

Pasteurization, salt purification, metal thermometers to control furnace temperature to assist in iron-making...a bunch of the most valuable projects were all given to the Department of Public Health in exchange for investment, and the others are not so valuable anymore!

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

Or the upcoming smallpox vaccine? This is even worse. Vaccines are not meant to make a lot of money! "

"You'd better think quickly!" Master Lin En opened the door and came in. Mr. Trocca jumped down from his shoulder, holding a gold-gilded post in his mouth, and sent it to Grete:

"Well, I've specially invited you to their party! If you don't want to sell yourself, just come up with something that can redeem you!"
