The discovery of pepper made Su Yan overjoyed, and the discovery of hemp made Su Yan ecstatic, the appearance of hemp will bring great help to the development of the dragon tribe, so that the dragon tribe can step into the era of agriculture with one foot, Su Yan is even ready to let the dragon tribe hold a grand sacrifice to share their joy with all the clansmen.

Now, the joy on Su Yan's face has all disappeared, how does the effect of wild pepper and wild hemp make Su Yan silent, the specific situation will have to wait until the pepper and hemp are ripe to know, the matter of holding a sacrifice, forget it.

Back at the tribe's residence, Su Yan didn't go to see the animals raised in the animal pen, but went directly back to the house where he lived, lying on the kang and closing his eyes and meditating.

Su Yan found that he was a little drifting these days, thinking that things would go smoothly as he thought, thinking that the Dragon Tribe would be able to grow rapidly.

Looking for crops, looking for metal veins to smelt metal, domesticating wild beasts, and collecting herbs, these four projects are the four key projects that Su Yan has planned for the current Dragon Tribe, as long as these four projects go smoothly, the Dragon Tribe will grow rapidly.

With his own presence, the matter of collecting herbs is easy to say, and it is impossible to succeed in domesticating wild beasts for the time being, but simple breeding is still feasible, and when it comes to the remaining two, it is Su Yan's real headache.

Looking for cultivated crops, now I can barely find two crops, as long as the land is reclaimed for cultivation in the coming year, it is equivalent to half a foot of the dragon tribe stepping into the era of farming, but unfortunately these two crops are not mainly to produce food, but it is not bad.

When it comes to farming, there is a big problem, the first problem is that there is no tool to reclaim the land; The second problem is that the adult labor force of the dragon tribe is too small, and it is very difficult to grow hemp and pepper on a large scale, and neither hemp nor pepper is mainly used to produce food, and the dragon tribe must continue to obtain food in the usual way.

There are two ways to solve the problem of land reclamation tools, the first is to use stone tools and wooden sticks to make rudimentary tools, which are expected to be less efficient in land reclamation; The second is to find metal veins to smelt metal, and use metal to build tools, which will be more efficient than the former.

The first method can be regarded as a reluctant solution to the problem, the dragon tribe has a small adult labor force, so at the beginning, cultivate a little less land, try slowly, and when the population of the dragon tribe increases, it can be planted on a large scale, maybe at that time it has found crops that mainly produce food.

In the end, looking for metal veins to smelt metals, Su Yan now felt that this was the most troublesome project, even if he found a metal vein, it was a very troublesome thing to mine metal veins.

The first is to choose metal veins for mining, with the conditions of the Dragon Tribe, the metal veins buried deep underground will definitely not be able to be mined, and you can only choose naked. Metal veins are mined exposed to the ground or up to two meters deep.

Second, the tools for mining the veins, the metal veins have not yet been mined, and naturally there are no metal tools to use, so they can only be mined with simple stone tools, which is inefficient.

The third and most important is the problem of manpower, the dragon tribe now has too few adult labor, hunting and fishing every day, even if it finds a metal vein that can be mined, how many people can be mobilized to mine, and finally how much ore can be collected in a month, and how much metal can be smelted.

As for the final smelting of ore, as long as the ore is mined, the smelting step is much simpler, so let's not mention it for the time being.

Whether it's farming crops or mining metal veins, it all ends up highlighting the same problem - manpower, the dragon tribe has too few adult laborers, even if they only cultivate crops or mine metal veins alone, they will feel understaffed.

The lack of an adult workforce is one of the most important problems facing the dragon tribe at the moment.

At present, the total population of the Dragon Tribe has reached more than 350 people, not counting the high-level leaders of the Dragon Tribe such as Su Yan and Wu, there are 58 adult males and 96 adult females, of which less than 60 are separated from the adult females who are pregnant and unable to do heavy work.

In other words, the adult labor force of the Dragon Tribe is less than one hundred and twenty people, although it is a lot for the Deer Tribe, the Mountain Tribe, and the Rabbit Tribe, but it is far from enough for Su Yan, who wants to make the Dragon Tribe develop rapidly, and a large number of manpower is needed just to mine metal veins.

The former snake tribe has passed the stage of weakness, and the current dragon tribe is still relatively weak in Su Yan's eyes, but in the eyes of other primitive people, the dragon tribe is undoubtedly one of the most powerful tribes in this area inhabited by the dragon tribe, except for the wolf tribe, the dragon tribe has not yet come into contact with other powerful tribes.

Weak when careful development, strong is to take the initiative to conquer and annex other primitive tribes in order to increase the tribal population and make the tribe develop rapidly, the dragon tribe no longer needs to pretend to be kind, under the leadership of Su Yan himself, conquering and annexing other weak primitive tribes is the best choice.

"The first target - the deer tribe." Su Yan had already decided to make the Deer Tribe the first target of the Dragon Tribe's conquest and annexation.

The Deer Tribe is the strongest of the three neighbors of the Dragon Tribe, and under normal circumstances, it should start with the weakest tribe to conquer and annex, but in order to prevent the Deer Tribe from moving away again, Su Yan took the Deer Tribe as the first target of the Dragon Tribe.

Although the deer tribe is strong, it is far from being the opponent of the dragon tribe, and the deer tribe also holds the salt that is very important to the dragon tribe, this year, the deer tribe and the dragon tribe have traded for more than a month, and the second transaction and the first transaction time are separated by a month and a half.

Salt is the main reason why the Dragons have chosen the Deer Tribe as the first target to conquer and annex.

First conquer and annex the deer tribe, and after the deer tribe is almost integrated into the dragon tribe, and then conquer the weaker rabbit tribe and the mountain tribe together, the total population of the dragon tribe will exceed 600 people, and the tribe of 600 people is undoubtedly the strongest group on the entire land in this era.

Halfway through the afternoon, Zhi and Biao came back with the hunting team, and they had a lot of harvest today, hunting an adult wild boar and catching a half-sized ewe.

Su Yan walked out of the room and summoned the four of them, Snake Witch, Tiger Witch, Zhi, and Biao, to the cave.

The four of Snake Witch, Tiger Witch, Zhi and Biao looked at Su Yan and didn't know what the king had done when he summoned them.

Su Yan: "I have decided to start a war and conquer the deer tribe!" ”
