In 8500 B.C., the originally arid and barren Sahara Desert and its surrounding areas suddenly continued to be moistened by a continuous drizzle after the rainy season, which greatly promoted the development of agriculture in the Mesolithic Age, and at the same time, due to the reduction of evaporation at the same time as precipitation, the growth of crops in this period was several times stronger than in previous years.

But as the rain continued, the human settlements in the area began to sense that something was wrong. Due to the prolonged drought, the vegetation cover in the desert is very low, and the sand and gravel itself has a poor water storage capacity, which leads to widespread and dangerous soil erosion after the rainwater is retained to a certain volume, while in the desert steppe and shrubland, excessive water accumulation has a devastating impact on the root system of plants, and a large number of plants die during this period, causing a further decline in land compactness.

With the rapid accumulation of rainwater, puddles of water have formed in the Sahara, and after the horrific phenomenon of the entire sand dunes moving with the water, these puddles gradually flow into the nearby rivers. The sudden increase in runoff overwhelmed the river, which rushed to both banks, flooding areas of farmland and forcing tribes that depended on river agriculture to relocate urgently. The multiplied river also carried away the sediment that had accumulated in the valleys on both sides of the river as it rushed down, and the flooding area was tens of thousands of paces wide, especially on the west bank of the Nile, where the Valley of the Kings and the Valley of the Emperors is now located, and the raging water carried away all the soft sand and gravel, exposing the basement rock layers at its base.

The impact of the wild accumulation of water on the grasslands is also very severe, and large areas of sub-Saharan Africa and the Nile basin are too wet to be inhabited, so people living here have to look for new habitats along the coast west of the Sahara, the tall mountains to the southeast, and across the Great Rift Valley. Some of these tribes eventually migrated to the Saharan core, where water was more evenly distributed, living in savanna-type environments.

However, this long-term precipitation also had significant positive effects: the increase in the Nile's sediment content led to the beginning of sediment accumulation in the Nile estuary, that is, the formation of a vast and flat Nile Delta, and the re-planning of the distribution of water bodies in the desert areas, washing away the original sand and gravel in these areas, revealing hard rock formations, which could only be beneficial to the tribes to establish new camps.

As for the fate of the Shin'ne-Nu tribe, which is entangled in the sub-Saharan steppes, it depends on what Hado thinks about on his way to the Falie cave.

Wading through waist-deep water in the col, Hado's gold and iron objects hindered his movement slightly, but at the same time shielded him from the impact of the branches and pumice stones in the water—in the water, he was not as agile as he was on hard ground, and it might have been difficult to move forward in such a dense body of water if it weren't for his incredible physical strength.

The path to the cave of "Fare" was covered with wooden posts and railings that craftsmen had urgently inserted into the mountain, allowing Hadu to climb and move forward. The excellent location of this cave is reflected at this time: the mountain wall outside the cave is intact and there are no plants rooting on it, so that the cave entrance only has water flow and no other debris; the inside and outside of the cave mouth are extended from the bottom up, even if the cave is flooded, its water level will not be higher than the inside of the cave, and because the cave entrance is close to the height of one and a half people, unless the water outlet in the col is blocked, it is impossible to submerge into the cave (after all, the cave is on the mountainside, and the nearby terrain has a strong hydrophobic ability, in fact, there is no "water outlet" at all The air circulation of the cave is blown out by the vents deep inside the cave, and the air is exhausted through the holes, so that the air quality in the caves is kept at a fairly fresh and healthy level.

But despite all these benefits, Hadu had trouble entering the cave: the ramp into the cave was too flat and slippery after being soaked in water, and Hadu failed to reach the top several times in a row - even if he jumped to the top of the slope with all his might, the water droplets on his body would wet the slope. After repeating this several times, he finally got annoyed, took off the copper thorn and plunged it into the ramp, and in this way he repeatedly stabbed in and out alternately with both hands, and finally climbed to the top of the slope with a "big image injury".

Hadu was amazed by the sight at the top of the slope: the hard stone wall that had been expected to take 30 fire seasons to be chiseled was now suddenly opened, and a passage of the same width as the cave walls on both sides was opened, and the breeze blew on Hado's face. Further inside, the walls of the cave began to narrow and press down until you had to bend down to get through. After groping for a while in the narrow passage towards the light, Hadu came out of the passage and saw a pool of crystal clear water. Looking up, you can see that the top of the cave is a small natural patio, there may be no pits on it, the water flowing from here is not large, and the rain can just be disturbed to fall in.

Stone pits have been dug into the walls of the cave around the waterhole, and copper and wood bars (actually iron trees) that can bear heavy loads have been inserted around the outer ring of the waterhole to the depths of the cave. Curious, Hado continued inside, and then saw his sister and her spouse playing happily with their newborn baby in their arms. When she found Hadu back, her sister screamed and shoved the child into her husband, jumped up and hugged Hadu so hard that he suddenly felt a little out of breath. Also, Hadu has been gone for more than ten years, which is just as the climate is changing abruptly and the tribe is affected, and it is the rarest thing to be able to see the backbone at this time.

Hadu sniffed a little about his parents and Mordo, and when he heard that it was all right, he was relieved, and then asked about the cave excavation, and then it became clear: the craftsmen had a great headache with the hard black stone, but later found that it was much easier to inlay this extremely hard stone in the tip of the copper blade and dig its stone wall—it was easy to think about, isn't it just hard, it seems that Hadu's order to collect these stones was extremely prescient. Speaking of the excavation of the cave, it can be said that it is now the third phase of the project - the first stage is to chisel through the wall, and the second stage is to expand the diameter of the passage along the ventilation duct - to carry out the functional transformation of the life of the cave. Build a trestle bridge to extend the path from Tan Bian, and then clean and expand the inner holes, gradually repairing a number of caves that can be inhabited. Due to the humid environment and the fact that the burning of torches would affect the air inside the cave, further works could not be started for the time being.

Because the cave** is well ventilated, the humidity in the cave is low, and the integrity of preserved food and various utensils is also extremely high, so there is no need to worry about food shortages - in order to ensure that the craftsmen can work smoothly in the cave, they are specially equipped with 20 times the total number of food reserves, of which 7CD is air-dried food, and there is no problem in preserving the whole fire season. The only possible problem is the way of food continuity: there are floods everywhere outside, except for the domesticated animals that have been brought to the high ground sheltered from the water as much as possible, other wild animals have escaped and died, and it is impossible to hunt and hunt;

To sum up, Hadu finally decided: withdraw. He gathered the craftsmen who were working in the depths of the cave, and prepared to join up with his family and plunder them to get rid of their "going to get sick". Then he found out that the leader of the craftsmen who are now carrying out the excavation operation is actually his elder brother, Mordo. It turned out that after so many years, Mordo had always wanted to help Hadu in the construction of the tribe (in fact, Hadu had not done anything else except to implement simplified symbols), but he always found that he was unable to do anything (or did not know how to start at all), and finally thought of coming to the "Falie" cave to learn masonry, and stayed for 12 years.

Hadu had a lot of apologies for this brother, but he knew that this was not the time for children to grow up—there were still a lot of clansmen waiting for him to decide. Hurriedly plundered, he began to arrange for everyone to clean up the cave, and then began to find a way to take them out together. At this moment, Hado's parents came up to him and said a thought that made him extremely silent.

Uta and Uma are too old to walk and can't go far.

People are old and don't need much food, so they stay in caves if they want.

The tribe is growing rapidly, and there are more and more young people, who can no longer keep up.

At least while everyone was packing up and ready to leave, Hado sat quietly beside his parents, and all three of them were silent, just waiting for time to pass. By the way, he plundered the food stored in the cave for "mold" and "rot", so that it could be preserved for a long time enough to be eaten.

In the end, Uta and Uma didn't make it through the narrow passage to get out with Hado—in addition to their own decisions, physical strength was a major factor—and they really didn't have the ability to travel long distances with their people. Hadu didn't speak, but silently used dry rattan to keep everyone around his waist to prevent it from being washed away by the current. Everyone didn't say anything, they all knew how uncomfortable Hadu was feeling now. Mordo stepped forward, stood side by side with Hado, and patted the old buddy he hadn't seen for a long time.

It's all in plain sight.

At this moment, the rain had decreased slightly, and it was a good opportunity to get out of the cave, and Hadu looked back at the passage that had been opened, and stared at it affectionately for a long time, before resolutely turning back and leading everyone out of the cave and down the mountain to join the tribesmen. The water had dropped along the way, but sharp gravel and twigs had begun to accumulate at the bottom of the col, requiring the group to walk carefully. In this way, they came to the border of the steppe by wading through the waterway.

Hadu counted the total number of people who were ready to transfer:

"Shin'ne-Nu", 7,3305 (900 who have been missing for decades and are still missing);

In order to ensure the continuous combat capability of the armed forces in the future, a total of 20,7202 people were carrying weapons and armor at the same time, including 4 handfuls:

Bronze weapons include 36,000 spears, 57,600 short blades, 2,1260 double-headed axes, 2,6575 double-headed blades, 12,600 long axes, 11,400 throwing blades, 1,3300 throwing axes, and 32,000 long sticks;

In addition, the "Honorary Chieftain Guard" formed in "Shin'ne-Nu" carries 1,200 pieces of copper spears, bronze three-headed flying blades, iron chain axes, iron visorels, copper-covered leather armor, stone-skinned horn rhino skin leggings, and short-haired cowhide leg guards.

At the same time, in order to prevent the problem of not being able to find minerals for production in a short period of time after entering the hinterland of the desert, Hadu also specifically requested the urgent mining of 67,220 copper ore (blue-copper-zinc ore) and 42,205 iron ore (hematite), and urgently inspected 2,400 trees on the eastern plateau of "Falie", cutting off the branches and leaving only the trunks to move with the team.

Fortunately, after so many years of breeding, there are more than 110,000 horses and about 86,000 camels in the tribe that are still healthy enough to travel long distances, so that they can lift and pull all the materials and reserves needed by these 870,000 people.

Once you've calculated everything you need to take with you, it's time to choose your route. The Hado and the cavalry patrols of the tribe consulted and finally chose to go down the river first, turn west at the point where the river bends its banks, reach an iconic solitary peak, and then turn northwest to follow the rocky mountains and finally reach the heart of the desert. The team was divided into three parts, with most of the patrol unit opening and reconnoitring routes first, the material transport team in the center, the infantry and the migration team of the tribesmen behind, and the elite and leader of the patrol force personally guarding the rear. As for the "Nin-Ham'me", Hado knew that they had a high talent for domesticating animals, so they took care of the domesticated cattle and sheep that followed the migration in the team.

The large army of more than 70,000 people set out after eating, and the procession dragged for more than 100,000 steps. At the end of the procession, beside him was the descendant of the Locke, as handsome as Locke, a white horse with a swarthy back, called Hip, and with the same eyes as his predecessors, and stood quietly beside him.

Hadu stood here and watched, unable to let go for a long time: he was born here, grew up here, unified the steppe here, set out from here, and finally returned here, but he didn't even have enough time or space to embrace the air here to embark on the road to the distance again—and he didn't know if he would return to this homeland in the future.

Hadu stood here sighing silently, unable to let go for a long time: when he was young, he had taken on the responsibility of the tribe, far away from his homeland in order to bring back peace, to dominate the steppe to quell the killing, and to return the people to a fertile land, and now because of this unstoppable force of nature, he felt powerless, helpless, and helpless - this was already an overwhelming force that his "wealth plundering" ability could not resist.

Hadu is standing here with the vicissitudes of life, unable to return to his senses for a long time: he is an adult at the age of 14, leaves home at the age of 35, and returns at the age of 50, how many 50 years can he have in his life, and can he spend another 50 years in his life? He will also age, he will die, he will also turn into ashes and scatter into the sky, and before that, he must ensure that his people can live a stable, prosperous, and peaceful life, and no longer move and lose their homeland like this - no need to conquer other human settlements, do not provoke other human tribes, just survive and reproduce, just survive well, and that is enough.

Hadu's spirit suddenly rose from the trough to the peak, and the vicissitudes of life suddenly bloomed with a resolute glow. Feeling the change in his master's aura, he snorted, and was very happy that his master was able to come out of the dark shadows in his heart.

Hadu turned and mounted his horse, chasing after the rear of the group.

In this way, he galloped to catch up with his people, and when he came to them, he dismounted, and did not look back at Fa Lie.
