The length of the shackle represents how far the slave can walk in one step, tentatively set at two feet, which can be appropriately reduced, but it is best not to be less than one and a half feet, less than one and a half feet, and the slave walks very hard.

Casting chains is a little more troublesome than casting chains, the chains are composed of oval rings, directly casting a small ring with a gap at one end, and then the gap of a small ring is smashed to death when the two small rings are connected in series, and the small rings are connected in series, and finally a chain is formed.

In general, casting copper shackles is not a very difficult thing for the dragon tribe, half a day to cast the various components of the shackles, and it takes less than half an hour to smash the small elliptical rings into a chain, and then it is impossible to continue to assemble, so it can only wait for the slave to be used, and the shackles are directly nailed to death with rivets.

The weight of such a pair of copper shackles is twenty-three catties, which is heavy enough, and a large amount of blister copper needs to be used, fortunately, the daily output of blister copper of the dragon tribe has exceeded two hundred catties, and some blister copper can be taken out every day to forge several pairs of shackles, and after accumulating day by day, the dragon tribe will have enough shackles to use.

In the future, when the dragon tribe conquers other tribes, once there is a fierce battle, it is no longer necessary to kill all the adult males, and directly reduce them to slaves and shackles to work for the dragon tribe, such slaves will hardly be converted into clansmen, and will continue to work until death.

Su Yan tried to smash the chain with a stone, and was able to "smash" the chain, that is, to smash the gap of the small ring, but it took a lot of effort, and it took several times to smash it, if the slave wanted to break the chain with a stone, it would take more time, and the loud noise would definitely attract the attention of the guards.

Shackles are either shackles or handcuffs, but the shackles of the handcuffs are a little smaller than the shackles of the shackles, and the slaves only use the shackles at first, and if there are slaves who are disobedient, then add handcuffs.

Before leaving the smelting area, Su Yan gave the snake to manage the smelting area a task, and the smelting area built at least three pairs of shackles every day.

The dragon tribe has been refining copper for many years, and with the daily output of blister copper skyrocketing to more than two hundred catties in twenty-two years, there is blister copper left almost every day, and the remaining blister copper is cast into copper pieces, put aside and piled up, if necessary, these copper blocks can be used directly.

Of course, the plan to refine pure copper has been going on, but it has not met Su Yan's requirements, let alone the development from pure copper to bronze, which is the pinnacle of the Bronze Age.

More than a month is fleeting, the hot and rainy summer is over, and the harvest autumn has arrived.

A very helpless thing, this year's summer rain is particularly heavy, and the fields cultivated by the dragon tribe are full of drainage canals, but the yield reduction has become inevitable, and it is expected that the yield will be reduced by up to three percent, and the dragon tribe can still bear it.

The rain not only affects the yield of crops, but also affects the construction of Takejo, which is expected to end next spring, and some families from Genjo and Akagi will be relocated to Takejo in batches in the summer.

The first thing to do in autumn is naturally a blind date, this year is the first year of the reform of the marriage system of the dragon tribe, and the people who have just become adults are somewhat uncomfortable.

Not counting the clansmen who just joined the dragon tribe this year, only fifty-two of the one hundred and thirty-seven male clansmen and one hundred and thirty-six female clansmen who have become adults this year have registered as husband and wife before the blind date is held, and the remaining eighty-five male clansmen and eighty-four female clansmen are still single, and they all decided to participate in the blind date, hoping to find their favorite partners at the blind date.

Few tribesmen are willing to wait until next spring for the tribe to arrange a partner for them.

Without the necessary fighting competitions at the blind date in previous years, the number of people who came to watch the blind date this year has been greatly reduced, and the blind date has almost become a festival for single people.

In the square in front of the temple, several bonfires are burning, and adult clansmen are busy around the bonfires, preparing food for the singles attending the blind date, and the beautifully dressed singles are scattered in various areas of the square.

There are men who take the initiative, and women who take the initiative, looking for the target to "hook up", feeling that they can see it, the two sides sit together and communicate, if they can't look at it, they shake their heads or wave their hands directly, and the other party naturally leaves here to find the next target.

There are also cases where more than one man has a crush on a woman or more than one woman has a crush on a man.

If multiple men fancy a woman, the woman can choose one of the men she likes to stay, let the other men leave, or let all the men leave; If the woman does not choose, that is, the strongest force can get her, the man will fight for her, the loser leaves, and the winner holds the beauty.

Multiple women fancy a man, women don't fight, they can only choose by the man they fancie, and in a patriarchal society like the dragon tribe, women and men can never be equal.

Men and women sit in pairs with each other, eating food, chatting, and getting to know each other better, until they get to know each other hand in hand, and then they leave the square hand in hand, go to the "household department" to register information, and form a new family.

The two formed a new family without consulting their parents first, which is also a flaw that still exists in the dragon tribe to this day.

When the children grow up, they are equivalent to being truly independent/independent, and they can make their own decisions about everything, and they do not need to consult their parents, who have no opinion on this, at most, they will bring their spouses home for their parents to see after forming a new family.

This is probably the reason why the vast majority of human beings in the primitive era died before they were old, the elderly need to be taken care of, and the most suitable to take care of the elderly is naturally their children, in the primitive era, there were many cases where children died before their parents, but fortunately, the situation of the dragon tribe is changing, and in the future, Su Yan will also formulate laws for young people to support their elderly parents.

The blind date is over, more than a dozen clansmen are still single, single men are mainly people with low force, and single women are mainly "ugly" people.

The next day, Su Yan summoned these dozen clansmen to the temple, looking at them who didn't know whether they were excited or scared causing their bodies to tremble, Su Yan smiled and said to them: "This year, only you are the only adult clansmen who are still single, you get to know each other, if you haven't found a spouse by the end of this year, and when it comes next year, you can only arrange it by me." ”

The single men and women looked at each other, as if they were choosing the person they liked, but helplessly, the "excellent" spouses were gone, and only they were left.
