The logs were driven deep into the soil to create a strong support. On the bracket, a wild deer was tied tightly, with its limbs spread out, clearly revealing its body and abdomen. At this moment, the injured wild deer wailed mournfully, its body heaved and struggled, but it did not die for a long time.

The female warrior Naxiu stood beside her, her arms were firmly pressed down on the shaking deer's head. The wild deer struggled for a while, exhausted its strength from the constant blood loss, and became a sample without moving.

Obsidian's short dagger was fast, and Shulot's hand was steady. He accurately cut the deer skin and cut the muscle, revealing the regular beating heart of the wild deer, but never hurt the artery, nor the deer lung above the heart, which was still breathing.

"Alyssa, my love. In Nahua we never speak of an organ by itself, such as eyes, nose, ears, mouth, and teeth. Instead, we say, my eyes noixteyotl, my nose noyacatzotl, my ear nonacas, my mouth nocamac, and my teeth."

Shulot pondered for a while, and did not rush to explain, but started from the traditional concept of Nahua language, and gradually integrated into the medical common sense of later generations.

"We say this precisely because the parts of the body cannot live without the body. They are not separate entities and need to be connected together to form a living whole... just like all my organs, all my bodies Parts, connected together, form multiple systems, and then form me."

"Sholot, I understand! You mean that the organs and what systems together make up the 'tonacayo' tonacayo, which is our entire body! And as the priests said, the vitality in our body comes from Sun, corn and water!"

Alyssa blinked and smiled knowingly. She looked at Xiulot expectantly, waiting for her lover's compliment.

In the Nahua language, "Tonakayo" is a combination of all organs and refers to a complete body. But the word can also refer to "whole corn" and "the warmth of the sun". "Tona" means the sun. In the traditional concept, the human body corresponds to the corn, and even more so to the warmth of the sun. Therefore, whenever the alliance offers sacrifices to the sun god, or prays for a good corn harvest, human sacrifices are required.

"Exactly! Tonakayo is the human body. In the whole body, there are nine organ systems, each responsible for different physical activities."

Xiu Luote paused for a moment, and decided to simplify the concept of the human body system, and try to use language that can be understood in this era to explain. He steadily stretched out the short dagger, used it as a teaching stick, and drew on the body of the wild deer.

"Alyssa, look, there are many organs in the body of this deer. There is a brain in its head, which can think; there are a lot of muscles in the limbs, which can run fast; the lungs in the chest are under the neck. Breathing up and down; below the lungs is the heart, beating to supply blood; behind the heart, there is a dark red liver, a brown red stomach, and then to a light red intestine, and a light red kidney... Together they are responsible for digestion Food and excretion; and under the rump, there are organs responsible for reproduction... Uh, this is a stag!"

Shulot froze, looked at a certain part of the stag, and was slightly surprised at the length. After counting breaths, he coughed lightly and made a conclusion.

"All in all, brain thinking, muscle movement, lung breathing, heart blood supply, liver, intestines, stomach and kidneys correspond to digestion and excretion, and then add reproduction. These are seven organ systems, corresponding to seven physical activities!"

"Hee hee, I understand, these are very easy to understand!"

Alyssa held back her smile, took a few glances, and bit her lips. Well, tonight, I want to make up for my lover... Then, she thought for a while, and asked suspiciously.

"Sholot, you said earlier that there are nine systems in the human body. According to what you said, thinking, movement, breathing, blood supply, digestion, excretion, reproduction... there are seven in total. Then, the remaining two What is it?"

"Well...the remaining two are not visible at a glance, but they are everywhere in the body."

Xiulot thought for a while, and gave an example that was not particularly accurate.

"If the human body is likened to a kingdom, and the normal operation of the body corresponds to the normal operation of the kingdom, then the eighth messenger system is the messengers running throughout the kingdom. The messengers convey various instructions and tell the city-states , As small as a village, when to plow in spring, when to harvest in autumn, when to pay tribute, when to mobilize, when to go to war... The messenger transmits instructions, regulates all aspects of the kingdom, and also regulates all aspects of the human body. We start from babies At the beginning, growing up little by little, the voice changes, the body grows taller, and the ability to sing is all the result of the messenger's guidance."

Hearing this, Alyssa's eyes flickered, and she fell into long thoughts. She believes every word of her lover, it just takes time to understand. After a while, she asked softly.

"Sholot, what is the messenger in the human body? How did it come about?"

"The messenger in the human body... is produced by organs, cells or glands. It is very small, and the amount is small but the impact is huge... a special kind of vitality."

Xiulot worked hard to organize the language, describing the concept of hormones in the human body. Afterwards, he exhaled and continued to talk about the last part of the immune system.

"As for the last immune system, it is the body's defense system. It is used to resist the invasion of pathogenic microorganisms and recover from injury and illness. They are equivalent to the warriors and militiamen of the entire kingdom. If foreign enemies invade, they will come from all over the kingdom. Mobilize everywhere, gather into a resistance army, fight to the death with the invading enemy, and fight to the end...The strength of the army determines the survival of the kingdom, and the strength of the defense system determines the life and death of people. We were cut, Being able to resist infection, heal wounds, recover from a cold, and stop coughing all depends on the body's immune system..."

Then, Xiulot glanced at the thinking lover, and added a few more words.

"In the immune system of the human body, warriors and militiamen are special cells. And their production comes from certain special organs, especially bone marrow, thymus and lymph... Simply put, the resistance to disease and Defense is collectively referred to as immunity, that is, immunity from diseases. The so-called ability of immunity is a kind of... um... and a special kind of vitality!..."

After speaking, Xiulot looked expectantly and looked at his lover.

"...Alyssa, do you understand what I said, the body's messenger and immune system?"

"Hmm...understood...a little bit."

Alyssa opened her eyes wide, filled with confusion. She first pressed her hand to her heart and made a gesture of understanding. Then, she spread out her white palms, curled up her fingers one by one, and finally only stretched out half of her pink little finger.

"Probably one palm... no, one finger... um... one fingernail is so much! Hehe."

Seeing his lover's playful actions, Shulot suddenly felt a headache.

Although the artisans of the kingdom have used priceless natural transparent crystals to grind out several rare magnifying glasses, they are still a thousand miles away from the invention of the microscope. Without high-power observation tools, there will be no real and visible evidence. However, in this age of ignorance, it is tantamount to spreading the common medical knowledge of future generations directly, and it may not last long.

After thinking about it, it is necessary to improve the level of the alliance's medical theory in a short period of time...the only feasible way is to combine with the medical inheritance of priests in this era, and use traditional cognitive methods to understand arguments!

Two steps away, Naxiu was thoughtful. She looked at His Highness who was thinking hard, and reminded tentatively.

"Your Highness, the special vitality produced by the organs~lightnovelpub.net~ maintains the operation and health of the human body... You mean the tonalli in the brain, the teyolia in the heart, Or 'ihiyotl' in the liver?"

"Huh? tonalli, teyolia, ihiyotl?"

Hearing these familiar and mysterious words, Shulot was slightly taken aback, and suddenly he was enlightened.

"Tonali", "Tejolia", and "Ihotel", these three words appear from time to time in sacred prayers and have very rich meanings. The three words respectively symbolize three different special energies, which have been passed down from generation to generation in the orthodox priestly education. They tell about the unique understanding of the human body and the world of the Aztec and Mesoamerican ancestors. And if the medical common sense of later generations is to be widely accepted by people of this era, it cannot do without these inheritances.

Shulot pondered for a while, and made a decision in his heart. He smiled slightly, looked at the cold female warrior, and ordered in a deep voice.

"Naxiu, you have received a complete priestly education, and you have also learned the healing rituals of the witch doctor. It is up to you to talk about the explanation of the human body in the priestly inheritance!"
