Jin Feng first took out a ball of thin thread and a small curved needle from his hand.
"This is no ordinary needle and thread. It can not only be used to sew clothes, but also to sew wounds. If necessary, it can also be used to fish."
Jin Feng couldn't explain things like bacterial disinfection to the escorts, but he still reminded: "But before suturing the wound, you must use fire to burn it, otherwise pus will easily develop."
The Ninth Princess and the person Qing Xinyao found took the ball of thread and looked at it curiously.
But the escorts were no strangers to suturing wounds with needles and threads, so they put it down after just one glance.
Under the expectant eyes of the escorts, Jin Feng took out a small whistle made of bamboo tubes.
Put it in your mouth and blow twice, and it immediately emits a sharp, penetrating whistle.
"The mountains in the south are high and densely forested. If you get separated or encounter danger, you can use this whistle to call for help. You can also agree on a secret code for communication."
"Tch, I thought it was some magical thing, but it turned out to be a whistle."
Qing Mulan picked up the whistle and looked at it, a little disappointed: "Isn't this the one that was removed from the sounding arrow?"
"Miss, don't underestimate this whistle. It can save lives at critical moments."
Amei, who was standing beside Qing Mulan, whispered.
"How can a little whistle save lives?"
Qing Mulan looked suspicious.
"For example, if someone is separated from his companions in the mountains, or is injured, having this whistle will save a lot of effort."
Amei said: "Miss, don't think this is not a big deal. Keep shouting, it consumes a lot of energy."
"That's true." Qing Mulan nodded.
On the stage, Jin Feng put down his whistle and picked up another pill.
"This pill is specially prepared by a high-ranking doctor. If you are injured, take one pill a day to detoxify and expel evil spirits, reduce swelling and relieve pain. Each saber is equipped with five pills."
This kind of pill was specially prepared by Wei Wuya for emergency use by escorts. Jin Feng did not ask in detail about what to use, but according to Zhou Jin, the effect was very good.
In fact, the penicillin cultivated by Jin Feng is more convenient to use, but he has been too busy recently and has not had time to make syringes and glass bottles, so he cannot carry it with him for the time being.
The needle and thread, the whistle, and the pills were not rare things, and Qing Mulan was a little disappointed.
But Princess Ninth breathed a sigh of relief.
However, before he could relax, he saw Jin Feng take out a small wooden stick.
Qing Mulan and the escorts also followed suit and took out small wooden sticks.
"These are matches, used to make fire."
Jin Feng took out the handle of the knife again: "Have you seen this place? Use the red end and rub it on it to make it catch fire."
With that said, Jin Feng gave another demonstration.
Hold a match and rub it on the handle of the knife, and a puff of white smoke will rise.
Then the stick started to burn.
Jin Feng placed the match under the prepared hay and lit it.
"This is good, this is good!"
Qing Mulan clapped her hands excitedly.
To survive in the wild, you often need to make a fire.
In the past, escorts used flint, fire sticks or bow drills to make fire.
But it is very difficult to make fire with flint and bow and drill. Sometimes it takes a long time to smash it and a long time to drill it, only to get a few sparks.
Huozhezi is convenient, but it is easy to spontaneously ignite and often burns in the user's arms.
In short, the previous methods of making fire had various problems.
Matches are much simpler. You can make fire with just a touch. They are much more convenient to use than the previous methods of making fire.
"The space of the knife handle is limited, and it can only hold so many things. It is used for everyone's emergencies."
Jin Feng reset the handle of the knife and clasped his fists toward the audience: "The rest will be hard for you all!"
"I will definitely live up to your expectations sir!"
The escorts responded with clasped fists in unison.
"I will definitely live up to your expectations sir!"
When the Ninth Princess and Qing Xinyao's people saw this, they also clasped their fists.
"Then everyone should rest early today and set off early tomorrow morning!"
Jin Feng nodded and jumped off the high platform.
He raised his eyebrows at the Ninth Princess and asked proudly: "Your Highness, how do you think of my saber?"
In the previous life, this saber was nothing and could be purchased online.
But Jin Feng spent a lot of time to make this kind of saber in Dakang.
It can almost be said that it represents his current highest level of craftsmanship.
From the perspective of science and engineering men, this is the most worthy thing to show off.
Although Princess Ninth was not a physicist and could not get Jin Feng's excitement, she was thoughtful and nodded cooperatively and praised: "It's very good. It's the most perfect saber I've ever seen."
As a master performer tempered by court battles, the Ninth Princess has a natural expression and a sincere tone.
If it were before, a straight man like Jin Feng would not be able to notice the abnormality at all.
But now his relationship with the Ninth Princess is further advanced than before, and he cares more about the Ninth Princess.
Although the look and tone of the Ninth Princess were normal, Jin Feng was still keenly aware that something was wrong.
"What's wrong? Are you unhappy?"
Jin Feng asked softly.
I also felt slightly disappointed.
This feeling is like that in his previous life when he worked hard to build a model and excitedly went to find his girlfriend to share it with him, only to find that his girlfriend was dealing with him.
Fortunately, Princess Ninth had much higher emotional intelligence than Jin Feng's girlfriend in his previous life. When she realized that Jin Feng was disappointed, she didn't deny it, but nodded slightly and whispered: "I can't say I'm unhappy, I just think you're a bit... rash."
"Reckless?"
"It can't be said to be reckless...how should I put it?"
The Ninth Princess pulled Jin Feng aside and said sincerely: "These things you just took out are all of great significance to me. The whistle, needle and thread, and pills are fine, especially the compass and matches. If used properly, they can
It can play a great role, and at the worst, it can earn countless amounts of money just like Shuiyu.
But you just gave them away for nothing."
Speaking of this, the Ninth Princess, who had always kept her expression calm even when the mountain collapsed, unexpectedly blushed for a rare moment and said in a low voice: "I'm not afraid of your laughter if I say it. Just now I really wanted to go find them and take the saber back..."
This time she didn't pretend, she was really sincere.
When Jin Feng heard this, he couldn't help but laugh.
"I thought it was something, but it turned out to be this."
"Isn't this not serious?" Ninth Princess said angrily: "I am feeling distressed right now, and you are still laughing!"
The Ninth Princess's words reminded Jin Feng of Tang Dongdong. The two of them were almost the same on this point. They both wanted to cover up Jin Feng's inventions and only keep them for their own use.
Such kind of Ninth Princess made Jin Feng suddenly feel a little more fireworks than usual.
She was no longer the aloof and indifferent princess she had been before, but more like the girl next door who pouted and acted coquettishly at him.
But this girl still calls herself "I".
Thinking again of the way the Ninth Princess looked at people with her chin raised, Jin Feng's heartbeat suddenly jumped two beats faster.
Subconsciously, I wanted to reach out and rub Princess Ninth's head, but seeing that there were many people around, I finally took my hand back.
