The defense is good training, and with previous experience, it is good to summarize a little and then readjust it according to the existing weapons, which is also the main direction of training for women.

But the attack was different, most of the people in the tribe had never participated in a major war, and the only ones who had experience were Shi Jiu's few people and the more than thirty captives.

Although the captives seemed to be more obedient, the tribe still didn't trust them very much after all, and Song Xuan didn't dare to believe what they said.

However, for their words, there is still some reference value, such as the weapons and equipment of the black feather and the combat power, the clearest understanding of this should be the newly captured captive, but whether it is fasting or food or beating, he has not been able to pry his mouth open, and occasionally open his mouth, it is just some cursing words, and there is no useful information.

Shi Jiu and the others also became captives after the Teng Snake rebellion, and they didn't know much information, saying that Wuyu's strength had increased a lot, but they didn't know much about the population and weapons.

However, Song Xuan learned about some other situations, that is, another tribe that has been at war with the Wuyu tribe, although the Wuyu tribe is hateful, it is indeed the main defense force in the north of this tribe, the black feather is close to the northernmost part of the long mountain range, and then over a low mountain range to the north is the grassland.

There are also many tribes on the grassland, many of them are strong, although the weapons are backward, but they have the ability to domesticate wild beasts, in Shi Jiu's description, it is a kind of creature that is larger than a deer, but has no horns, Song Xuan estimated that it should be something like a horse.

The cavalry has always been crushing the infantry, although there are conflicts on both sides, but it is generally the Wuyu tribe that suffers, but the year before last, somehow, after the war, the Wuyu tribe actually plundered a lot of people back, but unfortunately all this Shi Jiu They did not participate, so they don't know the specific situation, but those hundreds of captives can't be faked.

As for the rest of the harvest, it is even more unknown, the tribes further north do not seem to settle like the small tribes on the side of the Teng Snake, but run around, although the combat power is strong, but the population is not too large.

Every autumn, they will go south to raid, but there has always been the Black Feather tribe as a meat shield, so it is not too threatening for the tribes further south.

Song Xuan just learned a rough idea from everyone's mouths, and the Wuyu tribe in front of him had not been resolved, and it was too early for the others to worry about it now.

To the north of Teng Snake is a mountain range of hundreds of miles, and even if you go south to raid, it is difficult to run here, so you don't have to worry too much.

There is no substantial breakthrough in the understanding of Wu Yu, it is just that they have become more populous, in Song Xuan's opinion, the difference is not very big, it was a vague concept before, but now it is more vague.

The tribes of 1,000 and 2,000 people are similar to Teng Snake, and the pressure is very high, and the slightest carelessness will wipe out the whole clan and fall into the abyss.

In addition to daily training, it is more about preparing for next year's production, weapons, tools, these have a lot of gaps, most of the things have to rely on everyone to get themselves, even if a few people in the stone class are tired to death, they can't meet the needs of more than a hundred people in the tribe.

This is also a regular project in previous years, and it is not very difficult to do, but Song Xuan still got a lot of new gadgets for everyone.

Next year is bound to carry out large-scale reclamation, and the agricultural tools in the tribe are too lacking, whether it is cultivated or harvested, there is nothing good to use.

Although a few acres of land were planted this year, it was more like an experimental play, and most of the tools were improvised, and the effects of the improvised tools were naturally not very good.

Although there is a plow that can dig the ground, if you want to turn over the hundreds of acres of land, it is estimated that each person will dig several handfuls, and it may not be able to finish.

So it must be something more efficient, give full play to the existing animal power in the tribe, whether it is two cows or Uncle Lu's family, Song Xuan is not raising them in vain, although it has not played a role this year, but next year this knife will definitely not be able to dodge.

These animals in the tribe generally have only two purposes, either as labor, or to provide meat, and it is unrealistic to let Teng Snake raise them for nothing, even if they are prosperous, they have to help take care of the family and the home.

So Song Xuan thought about a simple plough out, the principle of the plough is not difficult, probably the top of the plow, and then the bottom of a shovel, if you want to be simpler, then just make a straight plow, there is not too much complex structure, but the efficiency is lower than the curved plow, and it is not easy to adjust the depth.

Since Song Xuan wants to do it, he must want to do it better, there are not many livestock in the tribe, Uncle Lu's family is just him and the two does, and the strength is slightly greater, and the other fawns are still a lot worse in size now, and it is okay to pull things that are not heavy, but it is still a little difficult to plow the land.

But even so, Song Xuan still has to make the straight plow first, at least there must be a guarantee, so that even if the later Quyuan plow is not successful, then there will be something to use next year.

The main body of this principle can be put together with four pieces of wood, one of the longest is for the animal to be pulled, and the two vertical ones are mainly responsible for connecting the shovels below, and there are also for people to hold by hand.

These four pieces of wood didn't take too long to put together, including the time of polishing is only half a day, of course, this premise is that Shi Ban has saved some wood a long time ago, if you start from cutting wood, it is estimated that it will not be able to do it in a day or two.

The structure of the plough is still easy to do, and the most troublesome thing is the plow shovel below, in Song Xuan's memory, most of this is made of metal, either bronze or iron, which is not only efficient, but also very durable, of course, in this era, it can only be replaced by stone or hardwood.

Whether it is stone or hardwood, it is not particularly easy to polish a suitable plough shovel, the simplest plow shovel is naturally triangular, as long as the ground can be dug up, but in Song Xuan's opinion, it is still too simple, the area that Teng Snake needs to reclaim is not small, if the efficiency is too slow, it will have a greater impact on other things.

Not to mention that there are not many people in the tribe who support farming now, it is basically Song Xuan's idea alone, in this case, it is naturally better to reduce the investment of manpower and time.

So when polishing, Song Xuan specially made the middle a little thicker, so that after the plow shovel was dug into the ground, it could automatically turn over the soil, looking at the rough stone plow shovel in his hand, although Song Xuan felt that it was not perfect, but it should not be too much of a problem to use, after all, it took him more than two days to polish it.

It's a pity that the only drawback is that the outside is now covered with heavy snow, otherwise you will know what the effect is when you get an interview in the field, Song Xuan first shoveled back and forth in the snow a few times, and there is naturally no problem in the face of this soft thing, although it looks ugly, but the effect is not much different from what Song Xuan imagined.

Then he went to Shi Jiu's place to take the clay and try it a few times, but these clays are used to make pottery, and in order to facilitate storage, the stone also added a lot of water to it, and this kind of resistance is obviously not something that the stone in Song Xuan's hand can deal with, but fortunately, next to the kiln, Song Xuan still found a small piece of land that was not frozen.

Even if the snow is falling, the stones will ponder to make pottery, but the number of kilns will become less, this kiln has just stopped fire, and the snow around it has also been melted by the high temperature, revealing the ground Although it was quickly soaked again, it still didn't have time to freeze after all, but it provided Song Xuan with a place to experiment.

The only drawback is that the plow shovel and the plough have not yet been assembled, Song Xuan can only push it with his hands at this time, simulating the state of traveling in the ground, although it is a little laborious, but where the plow passes, the soil is still turned over on both sides, although the depth of the turn is only five or six centimeters, but if it is modified later, it can be better.

Although this depth is not the most suitable for rice planting, and it is even much worse, it is also the most difficult step, if it can reach about ten centimeters, it is not a problem to barely plant, and the maximum yield will be slightly affected, but this is also more delicate than the legendary "slash-and-burn" farming.

It is not easy to tie the plough and plough together strongly, and even if the shape is burned out of wood, it is still difficult to assemble the two perfectly.

After pondering for a long time, the two didn't come up with a better way, so in the end, they still adopted the most primitive and effective method, that is, to make a few holes in it and tie it up with a rope.

The thickest part of this plough shovel is five or six centimeters, and it is not easy to grind through him, and in the absence of suitable tools, Song Xuan can only hold a bow drill in one hand and drill slowly.

Fortunately, the fire bow can also be used to punch holes, and now most of the holes in the tribe are drilled with fire and a combination of bow drills, not only the shape is more perfect, but the speed is also a lot faster, but it can only be slowly sharpened little by little when used to polish stones, but it can still be easier in the end.

This plough shovel can pour a lot of effort into Song Xuan, so he is also very careful when polishing, and a thick piece of animal skin is padded underneath to prevent it from being broken by bumping.

Seeing that the shape was available, Shi Ban began to polish it with wood, although it is easier to make the stone sharper, but after all, the material is placed here, once it encounters something hard, it is easy to break, although the sharpness and durability of the wood are not as good as the stone, but fortunately, it is more tough, even if the front end is dull, it will not take long to re-sharpen it, but it must be smaller and smaller when used.
