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

Since it is a lecture, naturally it cannot be piled up on the playground. Captain Leon Knight raised his hand and invited him politely. The bald bishop agreed with a smile and walked towards the meeting hall of the military camp together.

The priests followed suit. Grete fell back a few steps, trailing at the end, and came together with the little pastor John. The little priest immediately came over and said urgently in a low voice:

"I told the bishop!"

"What about the knight?"

"Yes!" The little pastor nodded quickly. Gretel smiled and patted his shoulder hard:

"thanks!"

The meeting hall of the City Guards was neither too big nor too small. There was a long table in the middle. The wooden board on the tabletop was obviously split from a whole tree trunk. It was not even painted except for being planed smooth. There is a map of Boss hanging on the wall opposite the door. If we squeeze around, about 20 people can sit down.

The bald bishop and the captain of the city guard entered first. Seven or eight pastors rushed in and immediately filled the conference room half full.

Gretel was sandwiched between the four squadron leaders and followed naturally. The squad leaders and soldiers behind also wanted to squeeze in. The squadron leader at the end glared at them and was about to close the door.

"etc!"

Flynn Knight stopped it just in time. He glanced at Gretel and saw that the young man kept looking back. He couldn't help but smile and waved to Captain Cullen who failed to squeeze in:

"Karen, come and listen too!"

There was a small commotion in the crowd. The soldiers who were not allowed to push each other and complained half-jokingly:

"Captain, this isn't fair!"

"Captain, we want to hear it too!"

"Captain, this is a way to save lives!"

Captain Cullen moved forward amidst the envy of his comrades. Grete looked left and right, and saw Brother Raymond and the others far away in the crowd at the entrance of the hall. It was really hard to squeeze in. After thinking about it, he turned to look for the captain:

"Captain, what I'm going to talk about is very useful to everyone. It can help everyone try to save their lives when they are injured. Do you think you can..."

He moved his palm outward:

"Get a bigger place?"

That must be possible! The captain naturally agreed, and the bald bishop had no objections. A group of people left the meeting hall and moved to the hall. Before anyone arrived, the smell of hot food was already drifting from the direction of the hall.

Gretel's stomach growled twice.

...How could he forget that the largest room in the city guard is the hall when ceremonies are held, and it is usually the dining room...

The soldiers and priests sat down to listen to the lecture, and Gretel stepped onto the podium without hesitation. There was no blackboard or chalk, so he made do with the simplicity and made vague gestures on himself:

"We use our lungs to breathe. When the lungs work, they are like bellows for burning fire. When you open the bellows, you inhale, and when you push it out, you exhale. Once the lungs are damaged, they sometimes form a one-way movement. The valve all leaks into the chest when inhaling, and cannot be exhaled when exhaling..."

He explained as simply as possible how tension pneumothorax came about and how to deal with it during first aid. Before the bald bishop could ask more questions, his tone dropped and he sped up:

"On the battlefield, there are many reasons for death. However, in addition to being killed immediately, many of them are seriously injured and cannot be treated by a priest in time. Now, I will talk about what kind of injuries should be treated first aid."

The soldiers are refreshed!

The squad leaders and ordinary soldiers were especially excited. As noble knights and the backbone of the battlefield, captains and squadron captains always find it easier to get treatment. The same cannot be said for civilians like them. Sometimes, a small cut on the hand of a noble master is more important than their broken hands and legs...

He can obviously survive! Some comrades can survive if they receive timely treatment!

"Little Grete is pretty good!"

Next to Captain Cullen, a squad leader touched his arm and whispered.

"Like his father." Another squad leader added.

"That's right, the captain was like this back then, trying his best to take care of us..."

A group of middle-aged men were talking in low voices, looking at Gretel with eyes filled with admiration and nostalgia. Gretel nodded to them and said in one breath:

"There are many reasons for death on the battlefield. The most important ones can be classified into three types. First, excessive bleeding; second, cardiac arrest; third, inability to breathe. Let's first talk about how to survive quickly on the battlefield. Stop bleeding..."

There was a commotion in the hall.

Heart arrest and inability to breathe, in the eyes of the soldiers, are basically serious injuries that will lead to death - or they can basically be judged to be dead. When this happens, most people's first reaction is to give up.

There is only blood. How many people watched helplessly as their comrades around them bled, unable to hold them down or stop them. In the end, he became weaker and weaker, and closed his eyes forever...

Little Grete wants to talk about how to stop bleeding?

Very good!

"Wait a minute!"

Suddenly, two or three voices shouted at the same time. Everyone looked around and saw two squadron leaders sitting in the second row jumping up and down:

"Little Grete, please speak slowly first! Let's get some paper and take notes!"

There was a sudden silence in the hall. Then, burst into laughter.

Gretel couldn't help but laugh. He waved his hand to Flynn Knight who jumped up, trying hard to tighten his muscles to prevent himself from laughing:

"Uncle Flynn, help me get two large pieces of paper and a board to hang them up. I need to draw some pictures for what I'm going to talk about next, so I can see clearly with the pictures -"

He drew pictures with his hands and explained with his mouth. From time to time, he would also find people to come up and give bandaging demonstrations. Everyone listened in rapt attention. When it was time for dinner, bread and bacon were brought from the kitchen, and everyone had a meal of vegetable soup and continued to listen.

Just after he finished talking about how to stop bleeding on the head and arms, a noise sounded in the distance. Getting closer and bigger.

Grete looked up and looked out the hall door, and at the same moment, several knights suddenly stood up, pressed their swords and turned their heads.

"who?!"

"who!"

"Team, team, captain!"

Boom boom boom, a series of footsteps. Outside the ajar door of the hall, a city guard soldier ran in as if he was desperate, holding on to the door and wheezing:

"Captain, the City Lord's Mansion is here to arrest someone!"

"What?"

"what happened!"

"The city lord's palace is arresting people. How come they caught our city guards here?!"

There was a burst of noisy discussion in the hall. More than 100 city guard soldiers whispered to each other, either shocked or angry, or confused. Some people were even confused and blurted out:

"Aren't we the ones doing the job of arresting people?"

puff……

Grete stood firmly on the podium. At this time, the city lord's palace came to arrest people. He could roughly guess why, and sure enough -

The door burst open. A well-dressed messenger led two guards and walked into the hall arrogantly.

"According to the order of the temple, Gretel Nordmark was summoned to ask questions——"
