Reckless snowfield, five huge figures like houses in the snowy night, these are five mammoths. Each elephant is covered with an armor made of bamboo and rattan, and the elephant is hunched on its back in a bamboo hut that can accommodate up to five people.

That's right, this is a remnant of the former traverser that Wang Qiang is looking forward to! Two days ago, a meteor fell from the sky, and the elders of the remnant clan learned that the divine envoy had descended again, and decisively sent the last warrior of the tribe out. Everything is logical in the predictions of the super players.

It has to be said that, as with all good traversers, the development of the predecessor was excellent. He is a doctoral supervisor at an agricultural university, and he is proficient in all aspects of wheat, sorghum, rice, corn, soybean, hybrid, rice, transgenics, and he came to the game because of an accidental car accident.

Even though he was an expert in agriculture, he was equally knowledgeable in basic astronomy and geography, and he looked at the stars at night, found the positions of the North Star and the Big Dipper, and some zodiac constellations, and calculated his latitudinal position, which should be the Yellow River region of the Central Plains. Then he also deduced from the position of the Big Dipper, which is different from later generations, that he may have been one or two hundred thousand years ago, which was the end of the fourth quarter of the Ice Age, and it was also the period when the earth's climate began to warm and human civilization began to bloom.

The alluvial plain of the Yellow River during this period was undoubtedly the most suitable area for the development of human civilization, and the low-lying areas in the middle and lower reaches of the Yangtze River were all wetlands and swamps where mosquitoes and flies breed left by the melting ice and water after the glacier retreated, and the environment was very harsh. But even so, the archaeological community has long found that during this period, there were human tribes in the Jiangxi Xianren Cave on the shore of Poyang Lake in the lower reaches of the Yangtze River, but it was too far away from itself, and the Hunan Yuchanyan, known as the ancestor of rice, was even farther away, and it was destined to have no civilization intersection in the early stage of the game.

The doctoral supervisor understands the rules of the game and knows his own abilities and specialties, and of course he has a response to the crisis in 5 years - that is, to establish a country in agriculture and use the population advantage to explode the mobility advantage of the nomads. As long as the population goes up, the productive forces go up, and the armament walls are there.

And the other party is a nomad, destined to have a population of not much, and if there is one less one on an expedition of thousands of miles, they can't afford it.

Bodao soon found a kind of wild wheat in the wild, very similar to the barley of the Qinghai-Tibet Plateau in later generations, the yield is not guaranteed, but the vitality is definitely as strong as weeds, and the staple food is it. The game system is obviously based on the traverser's strengths.

At the same time, the doctoral supervisor also found a huge hidden danger - a herd of wild elephants! No, much taller than the elephants of later generations, probably mammoths!

Ph.D. supervisors have become accustomed to the fact that there are elephants in only a small area of Xishuangbanna in China, and I really didn't expect that there were elephants in the plains of ancient China. In fact, if you think about it carefully, the story of Chinese chess, Cao Chong's elephant, and Shun Gengli Mountain all show that there were elephants in ancient China, not to mention the prehistoric era of one or two thousand years ago.

As a traverser, the doctoral director also wanted to be a Shun, so he saw the potential of the elephant: he could cultivate and transport in his spare time, and he could fight to deter the enemy in wartime, and at the same time, he also removed a major harm from the wheat fields that were about to be developed on a large scale. Moreover, the tribesmen also have rich experience in hunting and driving elephants from their ancestors.

The best time to sow barley is in summer, so it is necessary to get rid of the hidden danger of the elephant herd before summer. Therefore, under the careful planning of various traps of the doctoral supervisor, the elephants around the tribe were hit by a net and fell into the large pit dug and arranged in advance and raised in captivity.

Hunger is always the way to tame wild beasts, so even if the doctoral supervisor is a layman in this area, he has achieved a lot of results. As for the adult elephants that are really unruly, of course, they are not expected to be tamed, they exist as food, and the captivity of them frees up a large number of people in the tribe for the development of arable land.

After getting rid of the wild elephants, the doctoral supervisor has completely established his prestige among the clansmen, and the focus on "cultivated land" will be more convenient to carry out.

As early as in the process of searching for wild wheat, the doctoral director chose the terrain in the alluvial plain by the river, a large area of lush vegetation. Directly burn the weeds into ashes with a fire-the legendary "slash-and-burn"! Burning so much does not mean planting so much, but keeping a few more plots of land for the next year's wheat field to "rotate".

After carefully inspecting the humus layer of this land, Bodao found that the situation is not optimistic, the climate soil of this era is a bit similar to the frozen soil of Siberia, in fact, it is more suitable for growing potatoes, but the potatoes are native to South America, don't think about it, and now you can only make up for it with strict management.

Therefore, the doctoral supervisor is as rigorous as training doctoral students, and the clansmen are almost harsh to implement their own orders, all kinds of deep ploughing distances, field management, and day and night duty to drive birds and beasts, and not be sloppy for a moment. As a doctoral supervisor, his leadership education skills are undoubtedly 5-star, although the people do not understand, but they must also be understood in the implementation, and then executed in the understanding.

During the slack period after sowing, Bodao built a simple stone kiln with stones, excavated river mud and fired pottery to prepare for food storage and improved food hygiene. With the advent of pottery boilers, copper and salt smelting can also be carried out.

In the Yellow River Basin, the most famous inland salt producing area is Yuncheng, Shanxi, and there are copper mines in the nearby mountains, which is said to be the main city of the Chiyou Jiuli people. But very helpless, the doctoral supervisor only has five years of precious development time, with prehistoric traffic conditions there is no time to find mines, so there is only a very backward way to extract salt from the nearest stones. That is, when the pottery is burned, a pile of crushed stones mixed with red, purple and yellow colors are burned, which is the stone containing rock salt. Rock salt is very widely distributed and abundant in China.

You don't need to burn it for too long, otherwise the other ingredients will be burned into lime, and then the hot gravel is put into the clay pot where the boiling water is boiled, and the boiled water is a brine with a little salty taste. Then the brine is poured into another jar and boiled, which is equivalent to a purification.

In short, it is to keep adding ingredients to boil the brine in the second jar, which is enough, and there is no need to completely boil and refine the salt crystals. Although it has a strange smell, it is a "treasure water" rich in various calcium, magnesium, iron and other trace elements in the human body, and the taste immediately leaps when you add a spoonful to the broth. In fact, the dish called "stone pot fish" is based on such a principle.

So far, Bodao has been worshiped like a tribal god, and this brine has become the supreme treasure of the tribe!

If this achievement is worshiped as a god, then the back is completely the super-divine path of the traverser.

With the clay pot, the doctoral supervisor began to correct the tribesmen's lazar habits, that is, they must learn to use the "toilet" to hoard fertilizer.

Then autumn came, and the wild wheat in the fields was harvested! The doctoral supervisor has fired hundreds of crockpots, but they can't hold these wheat.

The clansmen cheered, but the doctoral supervisor was indeed very dissatisfied. Because these are the first generation of artificial wheat cultivated from the seeds of wild wheat, they are only about quantity rather than quality. As long as we go through the next round of seed screening, next year's harvest will be far beyond expectations.

But the problem also comes, the tribe does not have enough manpower. Building city walls and digging moats were also major projects, especially in the prehistoric era when tools were backward, and huge manpower was required.

Then, as a traverser, of course, you should do something about traversers, that is, ride ten domesticated juvenile mammoths to co-opt and deter the surrounding tribes.

Of course, if it is to eliminate the other party, it is a very simple matter, but it is really difficult to absorb the other party! Because, the language barrier! That's right, although the traverser has the language correction that comes with the system, but this is limited to its own tribe, and it won't work for other tribes!

However, after all, the doctoral supervisor is a five-star talent who is proficient in two foreign languages and has certain drawing skills, and the language barrier does not mean that he cannot communicate, and there are not many mural narratives in prehistoric times? This shows that whether it is prehistoric humans or modern children, comic books and even hieroglyphs are the most effective means of communication.

At the same time, the doctoral supervisor has realized that in prehistoric times, God was a universal belief, and if you want to recover the other party, you must show yourself as a god.

Therefore, on the bamboo tower of the elephant ridden by the doctoral director, it is to hang all kinds of flash ceramics, hang all kinds of flowers and ivory, and make a loudspeaker amplified microphone by himself, as soon as he speaks, all the clansmen and soldiers around him kneel and kowtow - this pretending to be a battle is already the extreme of prehistoric conditions. Although the doctoral supervisor is an agricultural scientist, he doesn't want to pretend to be superstitious, but it is indescribably sour, and it is difficult to extricate himself.

Then capture a few people alive, treat them to a meal of wild wheat paste brine broth, and then invite them to see the comic strip "Demon Cavalry Attack" and what to do, and send a crockpot of wild wheat back to show strength and goodwill of cooperation.

In short, after convincing people with virtue, the doctoral supervisor was worthy of the name of an excellent traverser, and in the autumn of the first year, he was "friendly" to the nearest two tribes and moved to live, and the mammoth perfectly played a strong diplomatic ability to move.

So far, the population of the tribe has exceeded 2,000! Then they began to intermarry men and women to strengthen ties, read comic books, learn to produce, and so on. Although everyone didn't pinch it at first, as long as there is food and spirit, you don't have to worry about the small details of various language barriers.

With a good start, the rest is snowballing. The population, walled city, and cultivated land area of the doctoral supervisor expanded rapidly in the next two years, and the focus of the doctoral supervisor's work was also on the formation and training of the army.

But Bo Dao is not an expert in cold weapon warfare, although he also knows from common sense that the bow and crossbow is the most effective means to deal with nomads, but the bow and arrow seem simple, but it is very troublesome to manufacture under the conditions of prehistoric times, and the bow with a range of up to forty or fifty meters made by bending a wooden pole is completely a child's toy and has no lethality.

Then simply practice throwing guns hard, and focus on throwing spearmen, the Roman Empire had infantry who specialized in throwing guns, and there was also a world record in throwing 100 meters in the Olympics. Bodao believes that even if the other party is a nomad and already knows how to ride and shoot, their bows and arrows should not be well developed, and they can be completely suppressed by numbers.

Of course, the idea is simple, the road is tortuous, and it is really a lot of helplessness to expect this group of prehistoric adult humans with unrestrained personalities to become an army in the real sense. The doctoral supervisor had to put his hope on the children from an early age, so the doctoral supervisor selected a thousand healthy children from tens of thousands of people in the tribe to focus on training, ensure nutrition, and named the Youth Pioneers.

Of course, only if they can wait until they grow. As a five-star traverser, even if you don't know about the military, you still have to have self-confidence.

During this period, the doctoral supervisor went out to prospect many times, and the farthest one rode an elephant to the hill seven days away, but perhaps limited by his own non-prospecting professional, each time he returned empty-handed, and as a result, within half a month of round-trip, there were many fights in the tribe, which made the doctoral supervisor realize the helplessness of "the family cannot be without an owner for a day". And what if a mine is discovered? Is it possible to abandon farmland and walled cities and move long distances to mining areas?

Then, in the fourth year, the problem came! The food produced by the tribe was no longer enough to feed a city of 40,000 people.

It was only at this time that the doctoral supervisor suddenly woke up and fell into the "Malthusian trap"! The gist of it is "the increase in the labor force of the population, so the production of food increases, and then the population is further stimulated, but the result is still not enough to eat!" The rate of food growth can never keep up with the rate of population growth, and then there will be famines, wars, and the population will fall, and the cycle will continue......"

Although this theory is very controversial, and the developed fertilizer agriculture and high-yield genetic crops of the 21st century have greatly alleviated this trap, the fact is that many countries are still not out of this trap.

What to do? Abandon the old, weak, sick and disabled population? Prehistoric humans did the same.

Tribal inbreeding was severe in prehistoric times, and the proportion of this vulnerable population was as high as a quarter, which was indeed a huge food burden. The doctoral supervisor with great "divine power" does not need to care about the evaluation of others, but the doctoral supervisor is still a civilized modern person after all, and he can't be so cruel, so he still gave the 10,000 people a few elephants and a large number of food tools, materials and seeds, and let them migrate to the south to find a sub-base in the mountainous area, only in the mountainous area can it be found copper and iron ore, which can be regarded as "waste utilization" to lay the foundation for the later period. If there is a late stage.

Then, the big tribe that traveled lightly finally had a great harvest in the autumn of the 5th year! At this time, the tribe can be said to be all soldiers, each of whom has prepared bamboo armor, bamboo shields, and even war elephants are covered with bamboo armor. Bo Dao believed that with the level of bows and arrows in prehistoric times, they would not be able to penetrate these armors at all, and they would never lose in frontal combat.

Then the people who were sent to the mountainous area to open the base actually traveled thousands of miles to bring good news, the copper ore and iron ore were not found, but they found a place with hot water underground, and the whole valley was a steaming place like spring all year round, where the grass and trees were very lush, there were mountains full of wild melons and wild fruits and mountain deer, not only 10,000 people could be fed, but also elephants could be fed.

The doctoral supervisor was surprised, originally the doctoral supervisor was already mentally prepared for their humane destruction, but he didn't expect that a year later, they would actually have a major discovery! They must have discovered the hot springs, and the doctoral director of the place where there is a hot spring in the southern mountains only thinks of one, the tourist health resort Lushan! However, the Lushan Mountain in later generations should be next to Poyang Lake in the south of the Yangtze River, right? Did 10,000 of them cross the river?

Don't worry about the river problem one or two thousand years ago, if you really find Lushan, then there are Daye Copper Mine and Jiangxi Copper Mine nearby! In particular, Daye is less than 200 kilometers away from Lushan, and the terrain of Lushan is steep, easy to defend and difficult to attack...... By the way, when you get there, you can build a boat to find the fairy cave from Poyang Lake, and you can incorporate a tribe, which is an ancient tribal site with rice left for more than 10,000 years, God knows how many people?

At that moment, the doctoral supervisor wanted to move the capital! But it was too late, and as soon as winter came, the nomads came.

What a hateful and lamentable! I only have 5 years, and it takes most of the energy to cultivate land and grow grain for all kinds of incorporated populations, and it is too late to explore the way, and it took 5 years for this Lushan to find out, this prehistoric era!

But he was not willing to be a doctoral supervisor at all, so he decided to relocate a thousand young pioneers from the tribe just in case. After all, the big war is coming, they are too young to play a role, and there will be danger, it is better to let them travel a long distance to exercise.

……

Then winter came, and when the frost froze the river, the nomads arrived as scheduled. Not much, two or three hundred horsemen stretched for several miles, looking like a guerrilla scattered. This made the doctoral supervisor who had been preparing for a long time secretly breathe a sigh of relief.

Then, something was wrong, these knights never hung out of the walled city, never engaged. This makes every time the mighty army out of the city, the powerful Bo Dao is powerless.

The only time he chased was particularly close, the doctoral supervisor finally saw the appearance of the other party, each knight was extremely majestic, and the height may be more than 1.9 meters, which was not seen before because their horses were also very large. And what is the average height of the strongest man in his tribe? About 1.6 meters! What does this mean? If there are too many people, they can't catch up with them, and if there are fewer people, they will easily kill them!

After that, the doctoral supervisor didn't chase anymore, just watched them hunt and catch fish and barbecue outside the city every day. The other party's cunning is beyond their imagination, and their toughness in not being afraid of the cold is even more beyond imagination.

The doctoral supervisor realized that he was going to lose! The other party is small and big, hundreds of them hunt a few deer a day and come over, and how much food do their 30,000 people have to eat a day? If they just spend it until tomorrow summer, and they can't sow seeds, won't they be finished? It's actually yourself who can't afford it!

……

There was no suspense, in the summer of the sixth year, the exhausted traverser launched the final national general attack, when hundreds of sharp arrows have an incredible range, accurate, and powerful concentrated fire shot through the bamboo armor that they were proud of, and shot themselves into a hedgehog, a long-lost car accident scene of the sharp pain surged all over the body!

The traverser instantly understood that he was an all-round backward in the tactical system, and even if he entered the Iron Age, he was not the opponent of the other party!

The next moment, the traverser saw the god who received him with a disappointed face in the white space, and only said one sentence: "I have a game of hemp and wheat ......"
