Chapter 160: Night Tuition Class? A Secret That Cannot Be Told
"What's going on?" Her father started yelling in a loud voice. He Zhaojun heard it and wanted to die on the spot.
She also heard someone laughing: "Why is my wife performing such a big ceremony today? It's not allowed, it's not allowed..." Wen Ziduan suppressed his laughter and reached out to pick He Zhaojun out of a pile of miscellaneous items.
"Why are they all here?" He Zhaojun looked at the people in the yard. Not only were the other six members of the He family there, but Wen Ziduan and Ling Buyi also came to join in the fun. Add to that the six members of the Cheng family and General Wan and his daughter, and there was no room left in the yard.
Wen Ziduan fanned her and said, "My wife is going to give a lecture to the soldiers, so I have to come and listen carefully, don't you think?"
He Zhaojun waved her sleeves and pushed Wen Ziduan away. "Stay away, it's quite hot!" Then, she awkwardly walked into the room, looked at the props that had been prepared long ago, and coughed lightly. "Please sit down, everyone. I only know a little bit, let's discuss it together."
Ling Buyi spoke first: "When I went to fight against the Xiongnu, there were always soldiers who were not injured in the battle, but gradually became unconscious and eventually no medicine could help them. What was the reason?"
"May I ask, have they undergone strenuous exercise and not been hydrated in time? When they are unconscious, their urine is brown and yellow, and they are in great pain? Even if you put them in cold water to cool them down, will they die faster?"
Ling Buyi nodded and leaned forward slightly: "Exactly. How did you know that?"
"This is because, after being exposed to the sun or the scorching wind and sand, the human body becomes dehydrated and the blood temperature is already high. If one were to quickly cool down by immersing the limbs in cold water, all the blood would be instantly pumped back into the internal organs, cooking them alive."
Several generals had fought in the desert and were horrified. Even if they took out all the cold water, it was difficult to save the soldiers' lives. Could it be that the previous methods were wrong?
He Zhaojun unfolded the flowerpot in front of her, revealing a cactus covered in thorns. "This was brought back by the caravan when they went to the border for trade. It's called a cactus. If you're short of water while traveling, try finding this and cutting it open."
As she spoke, He Zhaojun picked up a dagger and cut off a tuber of the cactus. "It contains abundant water. If it's large enough, it can feed two adults and save lives in a critical moment."
Cheng Ling was listening with great interest and quickly took a pen to draw the shape of a cactus while taking notes.
Hey, even the meeting minutes are there? He Zhaojun smiled and continued, "Next, I'll explain in detail how to drink water to maximize your chances of survival. The misconception is to drink in small sips to moisten your throat. The correct way to drink is to drink a fixed amount of water in a short period of time..."
The knowledge of wilderness survival was also very useful at this time. It even explained methods such as using leaves to get water. It also included some simple physics knowledge. However, they often heard He Zhaojun mention it, so they didn't find it unfamiliar or obscure at this time.
The lecture lasted until late at night. He Zhaojun glanced at the candles, which were almost burnt out. It was already late at night. She said, "Let's stop here for today and continue tomorrow night."
Ling Buyi nodded and bowed to He Zhaojun: "I heard about these things. You originally planned to tell the He family army. Can you allow me to tell the Black Armor Guards as well? After all..."
He Zhaojun shook her head gently: "Of course... no."
