"Oh, it's so lively!"

City Lord Qiao An staggered in. The people on both sides were at war with each other, glaring at each other, but he seemed not to notice it and looked around with a smile. If his beard was dyed white and lengthened three times, it would be incredible.

You can go cosplay Santa Claus.

"Lord City Lord."

"Your Excellency the Viscount."

Everyone present greeted each other with mixed greetings. Viscount Joan waved in this direction, nodded in that direction, and walked all the way to the center of the crowd. He stopped, stroking his beard and looking at Gretel:

"I remember you. You are that...the one from last Midsummer Festival...the disciple of Elder Erwin, right?",

"Grete Nordmark, I salute your Excellency." Grete bowed his head and saluted. Viscount Joan waved his hand scrawly:

"Well, you said there is evidence? Where is it? That bottle? Show me!"

"Seeing it requires tools." Gretel looked around: "Lord City Lord, if you allow me, I would like to find a brightly lit room to show you the evidence."

"Then what are you waiting for? Come in quickly!" Qiao Anzi raised her feet and walked towards the Spring Water Temple. After taking two steps, she turned back in surprise: "What are you doing?"

Grete rolled up the hem of her robe and was lying on the edge of the fountain, stretching her arms to scoop up the water in the fountain...

"The evidence is in the water of the fountain, Lord Viscount." Gretel went into battle in person, just to attract the attention of the city lord. After achieving his goal, he immediately stopped and stood up:

"Of course, for the sake of fairness, it is best if you send guards to get water. Or," he curled his lips and suppressed a smile:

"You can also get water from the priests of the Spring Water Temple..."

The bald bishop burst into laughter. Elder Erwin did not laugh out loud for the sake of his apprentice, and his white beard also trembled under the firelight. High Priest Horner's face was as black as the bottom of a pot, he snorted, and had to say something to

The city lord said:

"Please, sir, send guards to fetch water!"

"Remember to wipe the mouth of the spray bottle as well——"

Gretel walked in among the crowd, and while racing against time, he turned around and shouted...

A group of people entered the temple in large numbers. Gretel set up a microscope, and Viscount Joan went up to take a look, and his eyes lit up.

"Interesting, really interesting..." He walked around the microscope and exclaimed. Sometimes he put his finger over it, sometimes he pulled a sleeve, and sometimes he pulled out a hair and put it up to look at. After struggling for a full quarter of an hour, he remembered that there was a stick on the edge.

The guard, beckoning:

"Just use this thing to see things in the water? Bring it here!"

"Uh, it's not..."

Grete sweated profusely. Boss, nothing has been done about bacterial culture, fixation, and staining! What can be seen through microscopic examination alone?

Fortunately, Viscount Joan, who had gotten a new toy, was very patient and allowed him to fiddle with it. Gretel gave an order, and the priests of the Natural God Church and the Temple of the God of War came in two rows, one command and one movement.

Coupled with Elder Erwin's bacterial growth-stimulating technique, it didn't take long for the dyed bacterial samples to be delivered piece by piece to the city lord.

High Priest Horner walked around anxiously, but he couldn't just lift the table, and couldn't find any reason to stop him. Viscount Joan took matters into his own hands, fixed the glass pieces on the stage, closed his eyes, and looked at them one by one.

:

"This has!"

“There’s this one too!”

“There’s this one too!”

"This one doesn't have...oh, this one is made with cold boiled water..."

"This is the one that wiped the mouth of the fountain bottle..." As he watched, Viscount Joan's face slowly darkened, and he turned to High Priest Horner:

"Come and see for yourself!"

High Priest Horner reluctantly came over. Gretel stepped back a few steps and watched him finish observing one piece of glass and then changing to another. His brows furrowed tighter and tighter, and the movements of his hands became faster and faster. Beside him,

Elder Erwin pulled him quietly and said with worry:

"Little Grete, what if he says that we made these things and that we harmed him?"

"Then ask him to do it himself." Gretel raised the corner of his mouth. Teacher, you are so considerate... I was in need of someone to compliment me, so here you are...

"He collected water samples by himself, cultured them by himself, made smears and dyed them by himself. Don't worry, teacher, I guarantee that as long as the steps are all correct, the products will be exactly the same."

"That...that magic..."

"You don't need to use magic, just leave the aspic for 24 hours and it will be the same."

Bacteria are there if they are there, and they are not there if they are not. You can see it, others can see it, and you cannot deny it. This is the principle of repeatability in scientific experiments. Are you going to bite me?

Gretel's words became more and more certain. However, the face of the high priest Horner became darker and darker. He finally threw down the glass piece in his hand and roared:

"So what if you have this thing? It's a little bigger, you don't need this - this -"

"Microscope." Grete reminded him in time. Elder Erwin almost laughed: You might as well not mention it!

Sure enough, High Priest Horner glared at Gretel fiercely. After glaring, he remembered and continued roaring:

"What if you find something that you can't see without a microscope in a fountain? There are too many small things in this drop of water! Why do you say it caused the plague? Not something else? Why do you think it caused the plague?

What, it’s not like the poor themselves are sick?!”

There was a sudden silence in the temple. Lord Joan was stunned for a moment. The bald bishop scratched his head. Elder Erwin instinctively wanted to answer. He opened and closed his mouth and looked at Gretel:

...Yes, why do you say that this gadget can make people sick and spread the plague?

Gretel suddenly laughed. Amid the chuckle, he confidently took a step forward and held his head high:

"Of course I have a way to prove it."

At his request, Viscount Joan's guards turned around and went out, carrying ten rabbits. Eight were healthy and two had diarrhea. The three sect leaders, High Priest Horner, Bald Bishop, and Elder Erwin, took turns.

He took action and used the treatment technique to treat the healthy rabbits over and over again. Until he was sure that there were no problems, he started the experiment step by step under Gretel's guidance.

——Take the feces of healthy rabbits and sick rabbits and put them on the aspic respectively. Elder Erwin used a growth spell and threw it on them. After the magical spell was completed, he did a bacterial culture. In the feces of the sick rabbits, it was found out as expected.

Those short, stick-like gadgets.

"Healthy rabbits don't have gadgets like this, right?"

Grete smiled leisurely. Eight petri dishes were lined up, and no stick-shaped gadgets were found in the feces of eight healthy rabbits. Looking at his dazzling smile, the great priest Horner endured it again and again.

That’s why I didn’t throw rabbit shit in his face:

"No! So what?"

"Not very good." Grete shrugged and continued to the next step. He picked up a few bacteria from the gray-white round colonies in the petri dish of the sick rabbit and applied it to a newly sent, never used.

In a clean petri dish——

"Teacher, I have to trouble you again."

Throw the second growth technique on. The translucent aspic is quickly covered with round bacterial colonies. Cultivate the bacterial flora and verify the purity of the bacterial colonies. Then mix the bacteria with cold boiled water and feed it to the healthy rabbit. Wait patiently for a few seconds.

hours until they start to get sick——

As expected, the same rod-shaped microorganisms were cultured in the feces of the newly infected rabbits.

After everyone took turns to verify it, Gretel faced High Priest Horner, smiled and spread his hands.

"It can be found in sick rabbits; it can't be found in healthy rabbits. Things obtained from sick rabbits can survive, reproduce, and multiply, and are injected into healthy rabbits, causing exactly the same disease. From the second batch of sick rabbits,

The same thing has been isolated again - do you need any other evidence?"

The famous Koch's Law can be refuted on the spot, unless the goddess of spring water descends to earth immediately!

"Impossible!" The great priest's face was ashen. He suddenly turned around and ran to the main hall, knelt down in front of the statue, and hugged the skirt of the goddess with both hands:
Chapter completed!
