let go of that priestess

Considering that wolves start breeding when they are about 22 months old, we still have nearly two years to prepare, which is more than enough. "

"Oh, two years." Jiang Hongdou thought for a while, and then realized a problem: "That inbreeding... people will have problems?"

"Yes." Ji Cheng nodded, paused and said, "Although you didn't understand the principle before, you still made your own choices to avoid such situations.

Don't the Damu clan have three major surnames, and there are a small number of other clan members.

In fact, wild animals also have ways to avoid adult males.

This is an evolutionary tendency to avoid bad situations from happening. "

"Well..." Jiang Hongdou responded, and then added: "But the Damu clan has no mandatory requirements in this regard, so how can they be considered close relatives?"

"Close relatives within 5 generations, you can get married after 5 generations."

Ji Cheng also realized this while talking: "We have to set rules when we go back, otherwise the chances of the descendants of the tribe getting sick will be high.

To be honest, I have forgotten, common sense things are easy to ignore and forget.

It's better to communicate with multiple people, and it's better to talk more...Fortunately, I have you. "

"Hey." Jiang Hongdou blinked: "It's lucky to have you, you have helped the Damu clan so much, I..."

"Thank you again?"

"this......"

"It's not that I have no plans."

Ji Cheng sighed: "Like I said, I want everyone to be good together. When civilization develops, I can also enjoy the convenience of civilization. I don't want to live a lifetime of suffering."

"But no matter what, you will always and should be admired by everyone."

Jiang Hongdou whispered: "As for me personally, I, I...well, you come here."

As she spoke, she suddenly pulled Ji Cheng's hand forcefully, pulled him down, kissed his cheek, then continued with a slightly reddened face:

"Even if I put aside the feeling of wanting to thank you, I personally think that you are amazing, and I really want to kiss you..."

"..."

Ji Cheng and Jiang Hongdou looked at each other, then coughed and turned away, looked at the river that could already be seen, and changed the subject:

"Damn it, catch a fish."

"oh oh......"

......

A burst of fishing, the fish in the river have never seen this kind of formation.

The slippery fish scales and the difference in sight distance from the water to the underwater can't stop their fate of being caught.

More than half an hour later, Jiang Hongdou was already processing the fish scales, and Ji Cheng had already started to set up the grill, ready to grill.

"It's too easy!"

Jiang Hongdou exclaimed while handling it: "It's so convenient to get food! Why didn't we come to catch fish last year!"

"Because there is enough food."

Hearing this, Ji Cheng shrugged his shoulders, gathered firewood and said, "Did we lack food last year? It's just that the types of food are relatively simple.

This is the first reason, and the second reason is that eating fish is risky compared to birds.

Well, when I tried plants before, I only talked about the dangers of plants, and I skipped the dangers of animals. Let me talk about it now.

First of all, mammals are naturally non-toxic, except for those with poisonous bags, just remove the poisonous bags.

Secondly, birds are also naturally non-toxic, but occasionally a very few will be poisonous if eaten for a long time, because some animals and plants that are poisonous to humans will exist in their diet.

Although these animals and plants have undergone a transformation in the body of the bird, they inevitably still exist a little, and they will slowly accumulate in the human body after long-term consumption.

This is not the case with the white birds we raise. They eat earthworms, and we can eat them with confidence.

Finally, snakes, reptiles, fish, spiders, all naturally occur in venomous varieties. "

"Ah?" Hearing this, Jiang Hongdou's handling hand froze for a moment, and then continued to deal with it:

"Since you brought me to eat fish... this kind is not poisonous?"

"No, in fact, many fish are poisonous, and there should be some of them, but most of them are not too toxic, and there are ways to avoid them."

Ji Cheng chuckled, and after tidying up the grill, he also came over to the girl to help her deal with it:

"Remove the fish skin, fish head, fish glands, fish tail, and be careful not to break the fish gallbladder. We don't eat these, we only eat fish meat."

Chapter 72 On Penicillin

All the parts that could be removed from the fish were removed, and the blood was drained. In the end, only the white and clean flesh of the fish remained.

The way of handling it is a bit troublesome. This meal is... indeed a bit late, but it is safe.

I heard from Ji Cheng that grass carp, herring, carp, silver carp, etc. I don’t remember, they are all commonly eaten fish.

But these fish are all biliary poisonous fish, poisonous!

In addition, there are liver poisonous fish, blood poisonous fish, and egg poisonous fish, but people eat them all.

There is even a particularly troublesome species called pufferfish, which has toxins in its ovaries, liver, kidneys, blood, eyes, gills, and skin.

After death, the toxins in the internal organs will gradually seep into the fish. It can be said that the whole body is poisonous. In the end, some people still try to deal with it and eat it...

Reminiscent of the chili and Chinese prickly ash that Ji Cheng mentioned earlier, they have evolved aggressiveness, but they still have to be used as seasonings. On the way back to the village, Jiang Hongdou sighed with embarrassment:

"Man, eat everything..."

"Ah, indeed, people dare to try anything, and it is not an exaggeration to call it a devourer of the world."

Ji Cheng shrugged, paused to look at the girl and asked, "How is it? How does the fish taste?"

"It's delicious." Jiang Hongdou tilted his head and recalled: "It's just that some people can't describe the taste..."

"That's fresh~"

Ji Cheng laughed.

There is a lot of teaching content for this meal.

Knowledge of body structure such as internal organs, knowledge of toxins, and the knowledge of scientific cooking that is being taught again now:

"Umami is the fifth basic taste that is different from sweet, sour, bitter and salty.

Sodium glutamate, sodium inosinate, sodium guanylate, and sodium succinate are the main sources of umami.

Fish contains sodium glutamate and sodium inosinate.

When the fish is slaughtered, the proteins in the fish are broken down by enzymes to produce these amino acids.

By the way, spicy and spicy flavors are not counted as basic flavors because the mechanism of generating sensations is different. "

"Uh......"

Jiang Hongdou swallowed after hearing the inexplicable pressure.

Again!

Knowledge that is almost completely incomprehensible...

Only in front of Ji Cheng can she feel that her knowledge has been crushed, and she can't control her heartbeat.

"I, I only remember the five basic flavors, sweet, sour, bitter, salty and fresh."

She absorbed the knowledge seriously and said: "There is one more word, amino acid, I don't remember the others..."

"It's okay, I'm going to give you popular science slowly, and understand a little bit at a time~"

Jiang Hongdou has been by his side all the time. There is no doubt that her knowledge level is much higher than that of the priestesses including Yingying.

Ji Cheng calmly said:

"It's still a long time. According to your learning efficiency and seriousness, I am sure that within a few years, your knowledge level will reach a staged level, that is, you will learn general basic knowledge."

"Well, I will try my best to catch up with you~"

"Okay~ There will be no accidents when we go back, and I have to impart some other knowledge to you. I just thought about it when I was eating fish."

Ji Cheng said: "As the undoubted cutting-edge scientific research personnel in the village, we shoulder the important task of lighting up the village's technology tree.

Next, I think it is more important to improve the medical methods in the clan. "

"Oh." Jiang Hongdou blinked in response: "The treatment method, the treatment method.

Well, although it seems that the situation in the clan is good now, no one seems to be sick, but this is because most of the sick died on the way of migration. "

"Yes."

Ji Cheng sighed and said:

"Although we have allowed the tribesmen to take precautions to reduce the probability of getting sick to a certain extent, in fact, the serious illness will eventually come.

Sickness here is still a very scary thing...

And when the clansman gets sick again, we can't say it's a punishment from God, or use sacrifice and superstition to treat it.

So we need to develop drugs to fight against it.

Specifically, let’s talk about it when we go back to the village. "

"Okay!" Jiang Hongdou's face was serious, and he understood the importance of this matter.

When the two came back from the river, Yingying gave a breast massage and reported to them.

Sure enough, nothing happened while they were out.

The clansmen are still all rushing to their respective task progress.

Which means they both still have their own spare time.

Ji Cheng nodded, and took Jiang Hongdou to the kiln behind the village.

He took a branch and drew two lines on the ground, and then drew a branch from one of the lines, and said while drawing:

"Then, let me explain in detail. Regarding the medicine, there are currently two plans, and they must be carried out at the same time.

First, after the technical manufacturing groups 1 and 2 have completed the current tasks and assembled the spinning loom, they will immediately make several sets of protective clothing for the collection group to cover the face and arms.

Then let the collection team generate smoke to drive away the bees, collect the hives in the forest and bring them back to boil honey juice to obtain precious sugar.

Also, make another standard unit, volume, milliliters and liters.

Then add 25 grams of sugar and 2.1 grams of salt to 1 liter of water, fully dissolve and mix to make a nutrient solution.

This is the most basic medicine.

It may sound absurd that one of the greatest causes of death in human history is dehydration, but it's true.

As the body responds to many infections, it tries to expel the bacteria through the feces, which can eventually lead to fatal dehydration.

By drinking nutrient solution to ensure sufficient water in the body, the fatality rate of diarrhea can be reduced by about 93%. "

"Ah...um." Jiang Hongdou was a little confused, half understanding, but she was used to it.

This is true whenever a new technology is scaled.

After Ji Cheng's previous enlightenment, she also figured it out, just take it slowly, there is no rush.

He is training himself, and he will be his right-hand man in the future.

Thinking of this, Jiang Hongdou tried to analyze it in the way he understood:

"I remember, you said that adults are about 70% water, so dehydration can kill you, I understand that.

So, the first method is to prepare nutrient solution, what about the second? "

"the second."

Ji Cheng paused, looked at the kiln beside him, reached out and patted: "The second one is finally going to use another function of this thing——

Fire the glass.

With glass to make terrariums, what we need is a lot of glass petri dishes.

The broth is boiled from the bones of prey, and then the gel boiled from the hooves and horns of the collected animals is added to obtain the culture medium.
