From Chief to Ball

It sounds like a high-end technology, but the front-end technology is very simple.

Brewing, pottery, distilling wine.With these three technologies, this kind of preparation can be done manually, but it just takes more time to burn. This is not high-end technology, high school biology level.

If you want to double the chromosomes of a plant, you can use colchicine to induce it. Soak the seeds or seedlings in colchicine. He doesn't know the concentration, but it can be soaked hundreds of times. Record the situation next year and you will know. .

Colchicine is found in the day lily. If you eat too much day lily, you may be poisoned, and in severe cases, you may die. Since people can be poisoned, the content is obviously enough.

This kind of poison is very soluble in alcohol and water. It only needs to be soaked in a high degree of alcohol extraction, and then it will be concentrated by using the volatile characteristics of alcohol.

Under the current conditions, it is definitely not pure, there will be messy things like pigments in it, but what Chen Jian wants is just a certain concentration of colchicine, and it is not for experiments, so there is no need for any analytical purity.

It's like arsenic mixed with soil will kill you if you eat it. If it's just for killing people, why do you have to purify arsenic?

Now that there is food, the yeast koji has been improved for several generations, and the green mold is gradually decreasing, so it is no problem to use it to make grain wine.

Distilled wine is nothing more than because the boiling point of alcohol is lower than that of water, and it will boil at more than 70 degrees, so wine will turn into steam and fly out more easily than water.

Chen Jian probably knows the principle, these things are common sense, including everything he has done before.All that needs to be done is to combine this knowledge with today's crude conditions.

He has never seen a wine still, but the existing conditions are not impossible to have an alternative method. After closing the lid of the pot, a small hole is left to force the steam to escape from the small hole.

Fasten a pipe on the small hole, a pottery pipe will do, and it doesn’t need to be molded at one time. Now there are isingas, fish skin, pig skin, and thatch in the village, all of which can be used as links at the seams.More than a dozen pottery pipes are glued together, the longer the better.

Then get some earthenware pots with holes at the bottom and put them on top of these pipes. The perforated places are blocked with glue and leather, and cold water is filled in the pots as a condenser, so that the steam in the pipes is cooled to form a liquid to flow out.

Because the boiling point of alcohol is low, the earlier the alcohol comes out, the higher the concentration. This is called the head of wine in the countryside in the previous life, and the first distillation can reach [-] to [-] degrees.

In order to increase the concentration of wine, the ancients would choose to steam three times and brew three times, but in fact this is a method of getting twice the result with half the effort.The so-called Sanniang is to use wine as water to ferment grain again, but the yeast will not work when the alcohol concentration is high, so Sanniang is useless for eggs, and what is useful is only triple steaming. This dead end can be avoided up.

If the concentration of the wine distilled for the first time is not enough, it will be distilled again.Only the head of wine is selected for experimentation, and the tail of the wine in the back has a low alcohol content and can be drunk as wine.

Regardless of the cost, there is no need to consider the recovery of alcohol during the extraction of colchicine, even if it can be recovered, he would not dare to drink it.

If all goes well, with the right concentration of colchicine, perfect crossing with rye and rye, and only the beneficial genes are left, it will take three years to produce the first hexaploid wheat.

It seems like a long time, but compared to the tens of thousands of years of accidental variation under natural conditions, this is very easy to accept.

For a future farming nation, nothing is more important than good seeds.

Only when you are full can you have more children, and if you have more children, you can occupy the best place. Only by occupying the best place can the nation and civilization have a greater chance of survival.

All that is needed is a pair of hands and a head capable of applying the knowledge learned in middle school and high school, and no advanced theory is required.

Can't calculate the density of wine without a buoyancy meter to estimate the concentration of wine?Make a balance, make pottery weights of the same size, weigh the weight of a jar of water, and then weigh the weight of a jar of wine, do a division to calculate the density of the wine as a percentage of water, and estimate the concentration.

Can't calculate the concentration of colchicine without a spectrometer?It is manually divided into hundreds of parts, and the concentration of each part is reduced by one-thousandth, and the seeds or seedlings are soaked separately. It takes an extra year to observe which ones are tetraploid and which ones grow thick and deformed, and choose the appropriate concentration.

No return line to recirculate cooling water?Relying on people holding clay pots and pouring cold water into them is nothing more than a matter of adding a few more people, and it doesn't require too many people, nor is it ready for mass production.As for the inability to recycle alcohol and the like, it is even simpler, just don't want it, regardless of the cost.

When brewing and fermenting, do you know whether the fermented product is acidic or alkaline?After soaking the morning glory, it turns blue, which means it is alkaline. Just add some vinegar that has been cooked at high temperature. Acidic conditions are more suitable for yeast to convert sugar into alcohol.

All the problems can be solved bit by bit. The fourteen tribes exchanged two to three thousand catties of grain, which is enough for him to toss about. If the grain is eaten, it is only ten days' food for the tribe.

Local methods are sometimes effective. He habitually outlined all possible problems on the bark, estimated the possibility of solving them, and felt that this plan was feasible.

So after dinner, he and his clan asked for a few days off.

There is no complete division of labor between mental and physical power, and he positions himself as a "non-off-time cadre". Now he has to do a lot of work, and everything he does now is to lay a good foundation.

Just like studying in the previous life, why do you have to suffer so much to read books?Why not have fun?Why don't you learn from others and study abroad happily?

For a few years of pleasurable play can turn out to be a lifetime of unhappy play.Those children who study happily are all squatting in public schools, while those who stay up until midnight in private schools go to the Ivy League, continuing to fool more people to study happily.

It's still in its infancy, even if you want to be extravagant and lustful, you don't have that chance. If you leave the tribe, you won't be able to do anything, and you will starve to death; and the tribe will still live the same life without him, but progress will be slower.

After he made a suggestion, the clansmen happily agreed, and the men claimed that they would finish the land he should hoe, which was their trust.

Women can do the work of steaming wine; women can spin hemp that is about to be retting;

Chen Jian suddenly felt a little sad. His role for a long time... would be the director of the Village Women's Federation.

Chapter 12 Expedition

Everything is not a day and a night, day and night alternately passed the peach moon, bypassed the melon moon, and finally arrived at the fruit moon.

Usually, this is the busiest time of the year for the clansmen, and all kinds of fruits have already matured. Nowadays, people will not leave the village except to pick some during the ten-week break.

The wine is still fermenting and bubbling, and the hemp has to be peeled and dried after being fished out of the retting tank, and there is still a long time before it can be spun into thread.

The adults are busy harvesting the seeds that have not exploded and dropped ears, and carefully collect the barley meal waiting for the next apricot; the children also get the snack caramel from the by-products of wine making, and they know that the wheat has grown. The buds are so sweet, but I don't know why we have to use sprouted wheat for wine making, let alone why Brother Jian rejoices at a pile of moldy and wet wheat grains.

On the seventh day of the fruit month, the village ushered in the first group of tribes, a total of 13 people, all strong young men.

They were the tribe near the upper reaches of the Grass River, and the most active in this matter.

Along with them comes the dire news that another tribe has been attacked.

According to those who escaped, the people who rushed to the front were several members of Hua's former tribe. They loosened their hair and shouted in an incomprehensible language, showing their strength for the new tribe.

The people of the clan can't imagine what kind of situation this is, and why they can live together despite the hatred of killing relatives.If you haven't experienced it, it's naturally unimaginable.

A few days later, more and more people came to the village, bringing their own stone axes, bows and arrows or stone spears.

The people in the village have already prepared enough food, and an ordinary meal is already a very high level of hospitality in the eyes of those people.

Chen Jian counted the days. On the 15th day of Fruity Moon, ten of the fourteen tribes who made the oath last time came, one tribe was attacked, and three did not come. They were all tribes far away from the threat .

The chaotic village was covered with a murderous atmosphere. Chen Jian led the tribesmen of the two tribes to form a good team under the black and white flags in front of the village. clucking at their tidiness.

Song stood at the far left of the team, glanced sideways at those crooked tribes, and involuntarily stood up straighter, with his chest raised.He felt that if he rushed over with these thirty people, he would be able to knock down the dozens of people next to him.

Standing at the front of the team, Chen Jian didn't make any provocative speeches. Instead, he led a horned deer and purposely swayed it around in front of people.

"That tribe killed our people, of course we have to kill them back. That tribe has horned deer, sheep, and food for the winter. Every tribe that participates in this battle will get a share."

My own people were still quiet, because the drums did not sound, and speaking at this time was to carry a stone and hit a cane.The rest of the tribe shouted excitedly, and they too wanted to ride the horned deer, tall, rideable animals that held an irresistible fascination for men.

After Chen Jian said only this sentence, he beat the drum, indicating that the clansmen could disperse.There are a lot of things to do tonight, and a lot of things to prepare. The whole village is busy. He has to make final preparations for tomorrow's expedition.

The women busily prepared food, or carefully inspected their brothers' weapons and wicker armour.

Wicker garments strung together with buckskin and rope like tiers of leaves, they checked carefully for damage.

The unpregnant women of the tribe with different surnames silently looked at the few people they liked, whispered something to them, or carefully embroidered an extra piece of deerskin on their wicker armor, right where the heart beat .

The old grandmother kept wandering around the stove, reminding those who cooked the food not to forget to add salt to the lard, not to forget to fry the peas, she couldn't remember how many times she said it.The women didn't get bored either, and responded sentence by sentence, although they knew they would never forget.

All kinds of pendants and animal teeth, carrying the hopes and blessings of the women, are hung on the necks of their brothers or lovers.What was sung in the sunset was not a war song, but a love song that made people blush.
