"On these two crystals?" Feng Ruzhang picked up the crystal, looked left and right, but couldn't see the clue. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Lu Dian said: "These two crystals, one convex and one concave, can be placed at both ends of the copper pipe to achieve the effect of pulling the distant scene in, but in fact it is just an illusion effect." ”

"But how do these two phases work?"

Lu Dian frowned, he was afraid of something, it was really troublesome to meet a curious baby.

"First of all, we think that light travels in a straight line. ”

"Is the light the sun in the sky?"

Lu Dian nodded.

"Why does it go in a straight line? What does that have to do with this concave and convex mirror?"

Lu Dian scratched his head, this is completely impossible to communicate. The worldviews of the two worlds are completely different, and even the most basic perceptions are very different. Lu Dian rubbed his eyebrows, it seemed that he had to change to a way that Feng Ruzhang could understand.

"Ruzhang, do you know what this light is?"

"Light is light, what can it be?" Feng Ruzhang wondered if Lu Dian had suddenly short-circuited his brain and asked such a question.

Lu Dian shook his head and said, "If you want to understand my medical skills and even these strange techniques, you must first establish a cognition, that is, everything in this world is made of matter. Can you understand?"

"Everything in the world is made up of matter, do you think that this light is also a substance, and the true yuan spiritual power is also a substance?" Feng Ruzhang was not stupid and quickly expanded Lu Dian's concept.

Lu Dian pondered for a while and said, "It can be understood like this. ”

I'll show you something. As he spoke, Lu Dian took down a prism from the test bench and placed the prism in the sunlight, and a seven-colored ribbon quickly appeared on the cave wall. Lu Dian pointed to the ribbon and said, "The white light we see seems to me to be composed of these seven colors of light or even more light. It is a substance, even a decomposable substance, and this prism is the tool to disassemble it. Can you understand that most of my research uses this kind of research methodology?"

After Lu Dian finished speaking, he raised his eyes and looked at Feng Ruzhang. Feng Ruzhang was completely dumbfounded, looking at the colorful light on the wall in a daze and muttering, "The white light can be divided into seven colors? Sir, your strange art is truly a rare wonder in the world. ”

As soon as Lu Dian heard this, he knew that Feng Ruzhang still did not treat his things as a universal truth, but still regarded his own scholarship from the perspective of a cultivator, and regarded his science as a kind of cultivation technique, not even a practice. Lu Dian sighed and said, "Forget it, so be it." I'll just tell you how much you can understand your own ability. ”

Lu Dian took out a pen and paper and drew a mirror image for Feng Ruzhang on the paper, and explained to him for a while, but seeing Feng Ruzhang's dazed face, it seemed that this thing was too subversive for him.

"Sir, everything seems to be a rational word?" Feng Ruzhang muttered for a long time, and a sentence came out.

Lu Dian was stunned for a moment, and then said: "Yes, in my opinion, everything in the world follows one principle, there is a principle of cultivation, there is a principle of cultivation, there is a natural reason, and there is a reason for people." There is no escape from a single word for everything. ”

"In this way, the way of Mr. is very close to Lu Sheng's lineage, and I don't know if the inheritance is related to Lu Sheng. Feng Ruzhang said, as if he understood something, and his expression was relieved.

Lu Dian shook his head and said, "My reason is fundamentally different from Lu Sheng's reason. ”

Feng Ruzhang suddenly laughed: "Sir, it is really arrogant, the way of cultivating the truth in the world is inherited from the Three Sages except for the evil demons. Is it that Sir has found another way to open the heavens and canonize the saints?"

Lu Dian was silent. His knowledge is the crystallization of thousands of years of human wisdom on the earth, a methodology, a behavior pattern, and even an experimental habit are all summarized and condensed by predecessors after a hundred years, so to speak, Lu Dian itself is a huge treasure. What he knows is absolutely subversive to the world, not another way that Feng Ruzhang knows.

Feng Ruzhang smiled and looked at Lu Dian. Lu Dian said lightly: "Dissection itself is a technical job, but I want you to understand that we are not simply dissecting for the sake of dissection. We are trying to understand the similarities and differences between the sick and normal human bodies, and to provide a basis for medical methods such as pharmaceuticals and surgeries. As he spoke, Lu Dian picked up a pen and smudged the ink, and the ink penetrated along the white rice paper, and with the control of Lu Dian's painting skills, a picture of the appearance of the human body was gradually formed. Later, Lu Dian took out another piece of paper to also perform his painting skills, and a picture of the appearance of a woman's body jumped on the paper.

Feng Ruzhang smiled faintly: "I didn't expect Mr. to have such skills, I can admire it." This kind of smile is gentle with obscenity, and obscenity with the meaning that all men understand, obviously Feng Ruzhang misunderstood again.

Lu Dian said with a blank face: "There is no difference between men and women in doctors, and showing you the picture is to let you first distinguish the difference between the two different human bodies." ”

Feng Ruzhang snorted and almost laughed: "Mr. is really joking, I can still distinguish between men and women." ”

"Really?" Lu Dian glanced at him, then pointed to the lower abdomen of the female appearance map and said, "You tell me what is the difference between this position of men and women?"

Feng Ruzhang's smiling face suddenly closed, Lu Dian's question seemed simple, but he knew that the internal structure of the lower part of the dantian that Lu Dian was referring to was different from men and women. He had heard this from a mad elder in the family, but he couldn't figure out the difference.

Seeing that he didn't answer, Lu Dian continued to ask: "How many bones are there in the human body, and are the number of bones of men and women the same?"

Feng Ruzhang shook his head, he really didn't count the human bones with his heart when he saw a lot, who knows how many bones a person has, but looking back, this question seems to be very important to medical skills. If you can know exactly the number and location of human bones, you can definitely reduce a lot of trouble when treating some traumatic injuries. He secretly wrote down Lu Dian's question, and when he went back in a while, he must get a skeleton and count it.

"I'll ask you again. Lu Dian knocked on the chest of the female appearance picture and said, "Can you sue me why this position is different for men and women?"

"Hiss!" Feng Ruzhang suddenly gasped. Lu Dian's questions seemed to be simple questions, but why hadn't he thought about them before? Why? He stared at the two pictures of the appearance of the human body and had long since lost his initial yellowing thoughts, and now he was thinking about the questions raised by Lu Dian extremely seriously. He felt that there must be a secret of the human body hidden in these questions.

Lu Dian said: "A normal adult human body has two hundred and six bones, which are divided into three parts: the skull, the trunk bone and the limb bone. Among them, there are 29 skull bones, 51 trunk bones, and 126 limb bones. Newborn babies can reach 305 fast because many bones do not grow together, and the bones of children are about 217 to 218 during the growth period, because there are five sacrums in children, and they are combined into one when they become adults. A child's coccyx has four to five pieces, and when they grow up, they also form one. Children have two iliac bones, two ischial bones, and two pubic bones, which by the time of adults they merge into two hip bones. This adds up to eleven to twelve more bones in a child than in an adult. There is no difference in the number of bones between males and females, which is roughly the case. As for the problem of the mammary glands, I would like to explain it to you slowly when I have time, this problem is a bit more complicated than the bones, and it may take a little more time. ”

Feng Ruzhang was completely dumbfounded, and only two hundred and six pieces were left in his mind, why two hundred and six yuan? He couldn't wait to immediately find a dry bone to verify Lu Dian's words. Lu Dian's words really shocked him. Lu Dian even knew how many bones a baby has, how many bones a child has, and even knew why the number of bones changed. It's amazing! Feng Ruzhang felt that the Lu Dian in front of him was simply an amazing treasure, and his medical skills were absolutely unique in the world, because he had never seen that healer who could understand the human body to the extent that Lu Dian was almost perverted.

"Sir, are all these things true?"

Lu Dian nodded and said, "I will personally count it for you in the next anatomy learning process." ”

Feng Ruzhang said excitedly: "Sir, can we start immediately?"

Lu Dian shook his head: "Don't worry, let's start with the most basic human appearance......"
