Hearing the doctor say that the rabbit's injury was man-made, Nangong was angry, and said angrily: "Qiu Jieding, this bastard, he must have injured this rabbit, he did it on purpose, and wanted to use it to make soup, thanks to being stopped by me!" Ren Xiao hurriedly persuaded: "Don't rush to conclusions, if he wants to eat rabbit meat, he can kill it and bring it back!"

"Hmph, I'll question it when I get back!" Nangong put the little white rabbit bandaged by the old doctor into the box, and the latter said to it: "This wound seems to have been pierced by a sharp blade, and ordinary hunting weapons cannot cause this kind of wound!" Ren Xiao became interested after hearing this, and asked, "Doctor, can you elaborate on it?"

The old doctor said: "This little white rabbit is only a big palm, and hunters generally don't attack this kind of cub, and ordinary hunting tools will inevitably cause fatal damage to animals of its size" Nangong said to the old doctor in surprise: "I don't see that you still know how to hunt, doctor!" The old doctor smiled and said: "No, I don't know how to hunt in the down, but there were often people who went up the mountain in the past who were injured by the hunter's trap, and according to the size of these wounds, I slowly understood the tools and destructive power of hunting!"

"Then since the rabbit's injury was not caused by the hunter, how did it get injured?" asked Ren Xiao. The old doctor took a deep breath and said, "I saw this wound of the rabbit a year ago, and I was very impressed because it was very special. At that time, Baijietang had just moved here, and the business of my hospital was not affected. One day a wounded man came, his chest was bleeding out inexplicably, because he couldn't find the wound so he didn't dare to bandage it casually, so he came to the hospital for help, I wiped the blood stains on his chest, and found no wound, but after a while, his chest began to bleed again, and I saw that the blood gushed out of the atrium. When I touched the bleeding area with my hand again, I realized that the wound was there, and the reason why I didn't find it the first time was because the wound was so small that I couldn't find it without looking at it. ”

Ren Xiao listened with relish, and when he saw that the old doctor stopped, he hurriedly asked: "What happened to the wounded?" The old doctor took a sip of tea, looked up at Ren Xiao, and then said slowly: "Although his wound is very subtle, several major arteries connecting the heart have all been cut off, although the injured person will not feel strong pain, but the blood will soon be drained! In the end, because the best rescue time was delayed, the person's life could not be saved!"

Ren Xiao gasped and said, "There is such a strange thing, so that the wound on the rabbit's leg is the same wound you have seen before?, then how can you be sure that it was a human being?" The old doctor said: "At first, I didn't know that the wound of the deceased was man-made, and it was not until finally the wounded man said the reason for his injury before he died. Ren Xiao stared at the old doctor intently, he was completely attracted by this story, and the old doctor continued: "The deceased said so before he died, so-and-so you are so hateful, you are so hateful that you left this fatal wound on my body while I was not paying attention, and I will not let you go as a ghost!"

"I see, the rabbit's wound reminds you of the dead man you once had. Ren Xiao nodded thoughtfully, and then asked, "Then do you remember the name of the deceased at that time?" The old doctor shook his head and said, "I really have this."

I can't remember, if I remember, how could I not tell you!"

"By the way, old doctor, have you finally figured out the origin of this wound?" Nangong didn't speak for a long time, she kept thinking about every word the old doctor said. The old doctor showed a relieved expression, as if Nangong's question was what he wanted to hear. "It's not a blind claim, if this kind of wound is placed on an ordinary doctor, no matter how he investigates, he will never know the cause of this wound!" The old doctor's face showed a confident smile, and at this time, even the young man who had been working in his hospital couldn't help but say: "Sir, don't sell it, hurry up!"

"I see that you are all martial arts people, but do you know what is the most imperceptible weapon?" the old doctor ignored the young man's words, and still did not answer the question directly. Ren Xiao saw that this was the old doctor showing off his ability, and he was embarrassed to dismantle the stage, so he replied according to his rhythm: "The weapon that is the least easy to detect is of course the hidden weapon! Could it be that the master who used the secret weapon did it?"

The old doctor stroked his beard and said, "That's right, it's a hidden weapon, so do you know what is the most difficult thing to find in the hidden weapon?" Nangong replied, "Could it be the silver needle?"

"The girl is really smart, and she is indeed a silver needle!" the old doctor praised. Ren Xiao retorted: "But no matter how small the silver needle is pierced into the body, it will leave a wound back, besides, if the silver needle remains in the body, why didn't you find it at the beginning?" The old doctor adjusted his sitting posture slightly, and said: "Although I am not a person in the rivers and lakes, I have treated many martial arts heroes when I was young, and the wounds left by swords, guns, swords, and halberds are not the same, and the wounds caused by weapons are nothing more than skin and flesh or bruising and swelling, but there is one thing that cannot be seen on the surface after hitting a person!" Nangong understood at this time, and she said, "Old man, you want to talk about internal strength!" The latter could already see from her eyes that she had guessed everything, and gave her an affirmative nod.

"Why do I get more confused the more I listen, explain to me quickly!" Ren Xiao asked anxiously. Nangong took over from the old doctor and said: "For a master of internal force, it is not difficult for the internal force to transform into shape, if this person condenses the internal force into an insignificant embroidery needle, or even smaller than this, then the trauma caused is not easy to be discovered!"

"In that case, the killer must also be a doctor who knows a lot about the structure of the human body?" Ren Xiao moved his gaze to the old doctor, "Otherwise, how to explain the fact that the major arteries around the deceased's heart have been cut off, it must be these positions that the killer was aiming at from the beginning!" Nangong said: "What you said is not impossible, but although the structure of the human body is the same, everyone is different, not to mention the intricate structure of blood vessels, and the difficulty of aiming at the internal blood vessels from outside the body is comparable to ascending to the sky!" ”

After being denied, Ren Xiao asked unconvinced: "Then tell me, what should be going on?" Nangong said with a smile: "It's a shame that your martial arts are so high, and your understanding of internal force is only like that!" Ren Xiao rolled her eyes and didn't speak, Nangong continued: "Let's put it this way, when you attack a plank with all your strength, which position of the plank is destroyed first?" Ren Xiao didn't think about it, and said: "Of course I hit the place!" Nangong like

I already knew that he would answer wrong, and shook his finger and said: "No, the first thing to break must be the most vulnerable part of the plank! The same is true of the damage caused by the internal force, but as long as the internal force is controlled, it can accurately destroy the place it wants to destroy! I think the killer must have used this principle to first condense the internal force into a subtle attack that will not cause considerable attention to the naked eye, so that it not only evades the victim's detection, but also covers people's eyes and ears, and then uses the internal force to destroy the designated parts of the victim's body to confuse the public!"

Ren Xiao was stunned after hearing this, it was hard for him to imagine that there was such an attack, if the opponent he encountered was like this, then even if he died, he would never know how he died. "Having said all this, then the question is, if the murderer who attacked the rabbit is the same person, then why did he use such a powerful trick to attack this ineffective rabbit? And he only hit its hind legs, but did not kill it?" Nangong shrugged his shoulders and said: "This question can only be known by asking the person concerned, and we can only guess!"

After saying goodbye to the old doctor in the hospital, Ren Xiao and Nangong were about to go back to the tavern to put the rabbit down first, but they didn't expect that not long after leaving, they heard Mu Ziyi's voice on the street: "Isn't it just to give that little kid a toy, is it necessary to be so attentive?" Ren Xiao and Nangong followed the sound, and saw that there was indeed Mu Ziyi in a blacksmith shop on the side of the street. After the two walked in, they found that not only Mu Ziyi was here, but Luo Yun was also here, only to see him holding a short sword that had just been taken out of the furnace with pliers.

After seeing Ren Xiao and Nangong coming, Luo Yun said excitedly: "Yo, Nangong girl, it's too good time for you to come, come and help me!" Nangong had never struck iron, so he didn't know what Luo Yun was doing, let alone how to help him.

"What are you doing here?" Ren Xiao asked first. Mu Ziyi replied for Luo Yun: "It's not that I promised to send a toy to the little kid before, so I came over to make a toy!" Ren Xiao looked at the burnt red short sword and said, "It's just a toy, you're too concerned!" Mu Ziyi echoed: "Look! I just said this sentence!"

Luo Yun said with a smile: "Since I promised the little gourd, I must do it, this is called keeping my word!"

"But haven't you already made one for him out of wood? Why do you want to make another one? It's still an iron one, aren't you afraid that he will miss and hurt someone?" Ren Xiao said. Luo Yun didn't bother to explain to them, and said: "This is my business, you have to ask, if you can do it, you can help, if you can't help, don't affect me here!" Ren Xiao had no choice but to step aside. Nangong looked at the short sword and asked, "But how should I help you?" I don't know anything about forging weapons!" Luo Yun held the short sword with the pliers in his right hand, and then condensed a ball of internal force with his left hand, and said to Nangong: "You just need to do what I say!" Nangong Chuyan nodded, and Luo Yun continued: "Your control over internal force is higher than theirs, so the purpose of your help is to hope that you can use the same internal force with my internal force!"

Nangong raised his hand without saying a word, condensed the blue internal force, and said: "This is simple, then what should I do?" Luo Yun said: "Next, I will instill my internal force into this short sword little by little, and at the same time, I need you to cooperate with my internal force to instill your internal force into it!" Nangong said: "This is not difficult, can you start now?"
