The fleet went south to explore for nearly half a year, and it stopped before winter fell, and in the cold winter, not only the small river next to the dragon tribe would freeze, but even the surface of the big river would also form a layer of ice.

The river is too wide, I don't know if the ice on the river can carry the weight of people, maybe some tribes have tried to step on the ice river in winter, maybe it is safe to pass, or maybe the river surface is broken, anyway, the dragon tribe will not try such a dangerous thing.

After nearly half a year of exploration, at the end of the first month of autumn, the fleet finally determined the location of the Niu tribe's residence, next to a tributary of the great river, the fleet also entered this tributary, and even the fleet was discovered by the people of the Niu tribe.

It's easy to determine if the tribe you find is a cow tribe, just by seeing a cow.

Lu Shi clearly saw the figure of a cow in the distance, and this tribe has a relatively large population, so it is very likely that it is a cattle tribe.

For Su Yan, it doesn't matter whether this tribe with cattle is a tribe of cattle or not, as long as there are cows.

Autumn, the harvest season.

Last year, there was too much rain, and the 20,000 mu of millet, 3,000 mu of hemp, and 3,000 mu of soybeans planted were finally harvested only more than 760 tons of millet, nearly 100 tons of hemp seeds, and nearly 110 tons of soybeans, and the yield was reduced by several percent.

This summer saw abundant rains, but there were no floods and a bumper grain harvest.

In the spring, a total of 40,000 mu of millet, 6,000 mu of hemp and 6,000 mu of soybeans were cultivated, and finally a total of 2,100 tons of corn, nearly 250 tons of hemp seeds and nearly 300 tons of soybeans were harvested.

According to the calculation that the food consumed by two juvenile clansmen is equivalent to that of one adult clansman, each adult clansman can get about 570 catties of grain on average, and an average of one and a half catties of grain can be eaten every day, which is pure grain, and water must be added when cooking.

The people of the dragon tribe only eat two meals, morning and evening, and they can eat a large bowl of corn for both meals, and then add various dishes.

According to the Dragon Tribe's grain production this year, these grains are almost equivalent to one-third of the current population of the Dragon Tribe's annual food consumption, which is a very considerable proportion.

Wait until next year, the dragon tribe will cultivate more farmland, if next year is also a bumper harvest year, then the proportion of food produced by the dragon tribe will rise to half or even higher, and the dragon tribe has completely entered the era of farming.

Compared with hunting or fishing as the main way to obtain food, hunting and fishing have a population carrying limit, but there is no farming, the more land you have, the more food you get, then the more land you cultivate, and the development of the dragon tribe will no longer be affected by the problem of food.

The bumper harvest of grain is indeed a thing to be happy about, but Su Yan understands that food is very important to the Dragon Tribe, and meat is also very important to the Dragon Tribe.

Eating meat can make you stronger, and with the same weight of food, meat can provide more energy for the body than a vegetarian diet.

Food can be eaten at every meal, meat can not be lacking, meat and vegetables are matched, nutrition is balanced, especially the members of the hunting team and the reserve team, there should be more meat per meal, and the developing minors should also eat a little more meat.

Frequent hunting has reduced the number of beasts in the jungle, and the daily harvest of hunting is inevitable, and there is a way to solve it for the time being, and this problem will be repeated in the future.

The Sosaurus tribe was able to fish from rivers and domesticated animals on a large scale, both of which were able to obtain meat in large quantities.

The cultivated area of farmland is increasing, and the farmland produces grain and feed for raising animals, and the scale of domesticated animals of the dragon tribe is constantly expanding.

Farming farmland, fishing, and domesticating animals will be the main ways for the dragon tribe to obtain food for a long time, and perhaps as the population increases, the status of fishing will slowly decline, and the status of hunting, fruit picking, wild vegetables and plant roots will be even lower.

However, there are also problems that need to be worried, and the cultivation of farmland depends on the weather for food, and once it is a drought or rainy year, it will have a relatively large impact on grain production, but fortunately, the problem of grain production reduction can be alleviated to a certain extent by repairing water conservancy facilities, so that the grain harvest will not be lost.

Domesticated animals have to worry about the epidemic problem, once a serious outbreak of the epidemic, a large number of domestic animals will die, to a certain extent to solve this problem can only be divided into each family free-range, this matter will be implemented soon.

……

With the arrival of the first snow in winter, people who have been busy for most of the year finally get time to rest, but Su Yan does not have much time to rest, Su Yan has to make arrangements for various matters next year, and next year the Dragon Tribe will establish a criminal department and a ritual department, and preparations will be made in winter.

The establishment of the Criminal Department and the Ministry of Rites is only a key point next year, and more importantly, the Dragon Tribe will go south next year, and there is still a big war waiting for the Dragon Tribe.

After the bamboo city is built, then the fourth city should also be prepared, and the construction time was put behind by Su Yan, but the construction site of the fourth city needs to be carefully considered by Su Yan.

The fourth city will be built near the Great River, and there are two options, one is the south bank of the Great River, and the other is the north bank of the Great River.

Putting the fourth city on the south bank of the river is a step, and putting it on the north bank of the river is stable, thinking carefully about the gains and losses of building the city on the south bank and north bank of the river, and finally Su Yan decided to build the fourth city on the south bank of the river.

The Dragon Tribe is already a powerful tribe, and for the time being, no powerful tribe has been found to be able to pose a threat to the Dragon Tribe, even if the Niu Tribe who defeated the Blood Tiger Tribe may not even have one-fifth of the strength of the Dragon Tribe.

In this case, the dragon tribe no longer needs to be cautious, and directly strides forward, marching to the south bank of the Great River, conquest, non-stop conquest, conquering other tribes to gain population.

It can be said that marching into the south bank of the Great River to the Dragon Tribe is a new beginning.

Population has always been the most important factor influencing the development of the dragon tribe, and the northern region is sparsely populated and cannot be compared with the warmer climate of the south.

With the presence of ships, the tribes that live in the areas near both sides of the river and even the areas on both sides of the tributaries of the river will be the target of the dragon tribe, as long as the dragon tribe can accommodate it, the expedition team can fight for more than half of the year, and the dragon tribe does not lack the problem of food.

The general location of the fourth city is where the original Blood Tiger tribe lives, and the specific location needs to be investigated on the spot, the city lord, Su Yan decided to transfer Zhi over, separated by a big river, only Zhi will reassure Su Yan.

Holding the brush, soon, one piece of paper after another was full of words, and the planned projects in his mind were written down by Su Yan, which are all needed for next year.

In the room, except for a little movement made by Su Yan, all that was left was the noise of the two children, and the two sisters sat quietly, looking at the two children, and looked in the direction of Su Yan from time to time.
