For the next three months, Ding Qi stayed in the blessed land of Changcheng, and occasionally disappeared for a while, when he took the time to quietly go out. Patriarch Chen introduced this Mr. Ding to everyone, and everyone was very curious and respectful of Ding Qi. Everyone knows that he is a visitor from outside, confirming the legend of hundreds of years ago, and in their concept, those who can come in from the outside are great people.

Mr. Ding gave everyone a chance to take them out to find another home to live in, but he would not be reluctant, he would wait here for three months, and then whoever wanted to go would follow him. During this time, Patriarch Chen went door-to-door to persuade everyone to move, and Ding Qi also traveled all over the blessed land to find out the current situation here.

The area of Changcheng Blessed Land is not large, the terrain is roughly a plain surrounded by mountains, there are three villages, and the current population size is about 800, which is close to the limit of production conditions and natural resources.

Not all places are suitable for farming, and there is a cost-effectiveness problem between gathering and hunting, which makes these productive activities meaningless if they consume more energy than they gain. According to the existing production conditions, Ding Qi roughly estimated that the maximum population that could be accommodated in the blessed land did not exceed 1,000.

Ding Qi finally understood why the old patriarch had never found a suitable successor, because his options were too small. There are only 800 people here, excluding the old, weak, sick and disabled, less than half of their physical strength and energy are in a vigorous state, and among these 800 people, there are more than 60 people.

The so-called fool is a fool, born with a low IQ, and this proportion is too high. Ding Qi had heard Tan Hanchuan introduce that if a population wants to maintain its genetic diversity and not degenerate, the minimum individual size should be maintained at about five hundred, and the population in the Qin Gaotai world once dropped to this dangerous number.

Changcheng blessed land is a different situation, since this tribe moved here, it has always maintained the size of a few hundred people.

A lot has also happened in these three months. First of all, Ding Qi sacrificed the treasure of the Realm Control, and also condensed the entire Outer World into his heart. He asked Chen Angu what secret method the old patriarch had taught, and Chen Angu told him truthfully. Ding Qi practiced it himself, and left Chen Angu with the inheritance of the Divine Thoughts Heart Seal, and instructed him from time to time.

Interestingly, this is Ding Qi's Yuan Shen world, and in reality he has not learned the secret method of taking advantage of the blessed land. The so-called inheritance of the secret method from Chen Angu, and then turning back to guide Chen Angu after successful cultivation, is actually Ding Qi's own deduction, or Ding Qi based on the cultivation of the secret method outside the square, and created a secret method of taking advantage of the blessed land alone.

Ding Qi's version of the secret method of Chang Cheng Blessed Land, pretending that Chen Angu was taught by the old patriarch, evolved in this strange Yuan Shen world, and also included the Fengmen Heart Disk Technique. Among the eight secret techniques of the rivers and lakes, Ding Qi has studied the most and has the highest cultivation realm is the heart plate technique, which is more experienced than the other seven secret techniques.

Two and a half months later, Chen Angu had finally practiced the secret method and was able to open the portal with the treasure of the Realm Control. After ten years of studying with the old patriarch and not succeeding, Ding Qi taught Chen Angu in more than two months.

Now that Chen Angu can open the portal of the secret realm of heaven and earth, things seem to have taken a new turn, that is, the clansmen do not have to move anymore, and they can continue to maintain as before, and Chen Angu continues to play the role that the old patriarch once played. Of course, he can also use this as an opportunity to make another choice and take his people out to find another home.

Chen Angu asked Ding Qi for advice, what should he do, and whether the matter of moving can be slowed down? Ding Qi replied: "You have not changed the status quo of this place, you can cultivate the secret method, but you can make a choice. If I hadn't come, and you hadn't cultivated the secret method, you wouldn't even have a chance to make this choice!

Do you still want to be another old patriarch and then let future generations face the same dilemma? Even if you want to do this, let me ask again, do you know where to carry salt? The supplies outside are not picked up randomly, what do you exchange for alone?"

Chen Angu: "That's not what I meant. But I was worried that in this case, the people would not want to move, and it was only during this time that I finally persuaded some people to go with me. ”

Ding Qi smiled and asked rhetorically, "Why did you tell them?"

Chen Angu was stunned: "Shouldn't you tell the truth?"

Ding Qi: "I taught you the secret method, but I didn't want to take advantage of the blessed land inheritance to break off, not to prevent the clansmen from making the choice they should make. You don't lie to your people, but you don't have to say anything. ”

Chen Angu thought about it, and finally nodded and acquiesced to Ding Qi's suggestion. During this time, he did say that more than half of the people in this place moved out, because he truthfully told everyone the real situation at the moment, and Mr. Ding was only willing to wait for them for three months, and if he didn't go out, he would probably be trapped in this place forever.

Many people also came to Ding Qi to ask about the situation outside, to be honest, Ding Qi was not too clear about the details of the outside area during the Northern Song Dynasty, so he could only answer what he knew and tell them what kind of world it was outside.

Ding Qi found that every household was already packing their things, including those who claimed that they were reluctant to leave, but they were actually secretly packing up. Three months were fast in coming, and the village had finally run out of salt.

Why do people eat salt, Ding Qi also asked Tan Hanchuan when he was chatting. Because many people have the impression that other wild animals living on land do not need to eat so much extra salt, and they have nowhere to buy salt. Tan's answer is also interesting, it is said that this is a puzzle in the history of evolution.

The most significant difference from other terrestrial homeothermic animals is that the human body surface does not have such a thick layer of heat-insulating hair, the subcutaneous fat layer is not thick enough, and the skin is very fragile and delicate, full of capillaries, and sweat glands are very developed. As a result, humans have an advantage over other animals – heat dissipation is very fast.

Learning to wear clothes to keep out the cold is also a sign of the birth of wisdom, and if there is no wisdom and no hair, the human species would have been extinct long ago. When did people start to shed their hair? It should be when they learn to consciously and actively replenish salt, accompanied by wisdom and clothing.

In addition to the skin system, humans have two systems that are significantly different from other animals. One is the nervous system, including the brain, which has a very high proportion of total weight to body weight and consumes a lot of calories for complex thinking activities. The second is the digestive system, which includes the stomach and intestines, and its total weight as a percentage of body weight is very low, so it requires a high frequency of continuous eating to maintain physical strength.

Some animals can store more than half or more of their total body weight after a full meal, and then they can stop eating for a long time and just lie on their stomachs in the nest. And human beings can never do it, I have never heard of a person who is more than 100 catties when he is hungry, and he can eat dozens of catties of food in one meal.

It seems to be a disadvantage in terms of survival, but it has become a great advantage from a different perspective. Human endurance is very good, can continue to maintain a certain intensity of exercise for a long time, can work continuously, or continuous output under stable power.

If we simply look at the strength, people will definitely not be able to compare with oxen, and in terms of speed, people will not be able to compare with horses. But when hunting in groups, people are constantly chasing and rounding up, and eventually most of the prey can be exhausted. Of course, otaku in modern cities will no longer and do not need to give full play to this physiological advantage, but they will also continue to consume and consume calories to do something else.

Because the body's heat dissipation function is very good, the burden on the digestive system is small, and it will not lead to hyperthermia during continuous exercise. For example, if a group of people chase a herd of deer with spears, the speed of the deer herd can quickly throw people away, but when they have to stop to rest after running a certain distance, the hunters will slowly catch up, and eventually the herd of deer will be consumed alive.

Many animals can't run fast after they're full, and they can't run far when they're hungry. Wild horses, which are not bred in captivity and carefully cared for, are far from being human opponents in this kind of endurance competition of continuous pursuit.

More importantly, people can continue to work day after day, and this kind of labor is relatively high-intensity, working under the conscious command of the brain, and the production efficiency is incomparable, which is also the basis for the development of a civilized society. Human physical labor itself is accompanied by the process of mental labor.

In order to do this, in addition to constantly replenishing food and water, people also need to maintain electrolyte balance and consume a lot of salt. Electrolyte intake in a natural food environment is not sufficient. If the salt intake is insufficient, and only other foods are eaten, the person will lose this stamina advantage, and the efficiency of doing everything will drop dramatically.

There is a real story. During the period of resisting US aggression and aiding Korea after liberation, a major general of the Central People's Republic of China who was lurking on the mainland received an important order from the Taiwan side, that is, he must find a way to destroy the Chongqing mustard factory! Because at that time, mustard was an extremely important military material to be transported to the front.

Lao Tan's original conclusion was: In a sense, man is the most efficient animal, but he has to take in a lot of extra salt, which is due to evolution. As for why people evolved like this, Tan Hanchuan can't explain it, anyway, it became like this. If we continue to discuss it, I am afraid that it will become another question that Ding Qi and others have pondered, is evolution itself conscious?

In short, the salt in the blessed land is exhausted, and everyone is aware of the crisis except for those fools. On this day, the patriarch Chen Angu organized a general meeting of all the clans in the wilderness, and each family had to send a representative to participate. Chen Angu didn't talk much nonsense, so he directly announced his decision to leave here early tomorrow morning and lead his clansmen to go outside to find another home.

After this period of communication, about 500 people are willing to follow him. There were more than 300 others who suggested staying, but they did not advise themselves to stay, but to advise all the people of their clan to stay here.

At this time, a young man brought a stool, stood on it, and made a generous speech, which was really difficult for him, and his performance was almost like a speech in later generations. Ding Qi already knew this young man, his name was Yang Fulai, and he was one of the few literate people in the local area, and he looked very similar to Yang Chengong, the lord of the blessed land of Changcheng in later generations, or Yang Chengong, who was more than ten years younger.

Yang Fulai stood tall, waved his arms and said excitedly: "Even if you enjoy a hundred years here, you are lustful and ignorant, how is it different from dying in the twilight of life? Even if it is death, I want to go to the outside world to see!"

Ding Qi didn't say much, this clan meeting was just a notice, anyway, he would open the door tomorrow and leave, whoever wanted to follow him. The next day, after the rooster crowed, the team packed up and left the village, Chen Angu was still thinking about the more than 300 clansmen, but Ding Qi told him not to worry, those people would follow.

As Ding Qi expected, everyone followed the big team. Those clansmen who were reluctant to leave had actually been prepared for a long time, and when they saw that everyone was really going to move, they didn't want to stay alone, and those fools were also called to go on the road together.

After opening the door, Ding Qi told them another thing, most of their things couldn't actually be brought out, unless they were brought in from outside. It has come to this point that people have had to abandon a lot of supplies.

Dan Ding Qi also prepared in advance, and ordered the men and women to form separate formations, because most of the people had no clothes on their bodies after going out, so they took the prepared grass leaves and leaves outside the door to cover their bodies, and carried chickens and dogs and the like to continue to move forward.

Fortunately, they did not walk far, and they picked wild peaches that were ripe on the way to satisfy their hunger, and they walked more than three kilometers until sunset to reach the No. 5 valley. A lot of simple sheds have been built here, and some materials have been piled up in the sheds, which are the preparations made by Ding Qi with Chen Angu in the past half month, and the weather is not cold now, which can give the clansmen enough buffer time.

Ding Qi told Chen Angu to lead his clan to settle here, and not to bring them back after they came out, but Chen Angu himself could take the time to go back, and he should also select a successor to continue to teach the secret method of taking advantage of the blessed land, so that the treasure of the control realm and the inheritance of the secret realm of heaven and earth will continue to be extinct.

After the group of clansmen had been settled for the time being, it was already dark, and Ding Qi returned to the blessed land of Changcheng alone, and came to the center of the village, still sitting alone under the big tree. When the rooster crowed in the village, the sky was already slightly bright, and Ding Qi finally opened his eyes and stood up.

Ding Qi had already left the realm, and what he saw was not the morning of the Song Dynasty, but the ruins of the village eight hundred years later. This is a very fantastical experience, Ding Qi looked down at the peach pit in his hand, this thing has been refined into a magic weapon by him, it seems that it still contains a magic weapon of vitality.

How to describe this feeling, this peach pit seems to contain a world, if it is planted to grow and sprout, it seems to be able to evolve into a blessed land. But this is just a feeling, it's not like Ding Qi can really grow a blessed land, at least now he doesn't have the ability.

So what is the real magic of this peach pit? It is equivalent to a new treasure of world control! Ding Qi created another set of secret method inheritance for the blessed land of Chang Cheng in the Yuan Shen Realm, and sacrificed another treasure of world control. If he passed on this set of secret methods and the treasure of controlling the realm to others, as long as the person who had to teach it was successful, he could still control this secret realm of heaven and earth.

It may be an exaggeration to say that he completely controls the secret realm of heaven and earth, but at least he can control its portal, and he can also use this peach pit to sense heaven and earth to continue cultivating here. For Ding Qi himself, this peach pit is actually of little use, he has a secret method outside the square, and the Jing Wenshi he sacrifices can open the portal to any outside world, and there is no need to do it at all.

But from another perspective, this peach pit is very significant. It is specially refined by Ding Qi for the Changcheng blessed land, and it also cooperates with the corresponding secret method, which is equivalent to a backup of the inheritance of the Changcheng blessed land.

It is impossible for everyone to have such a cultivation as Ding Qi, even if it is Ding Qi himself, it is only after cultivating to break through the Seven Realms that he can truly open the portal and lead others in and out of the outside world without the help of the treasure of the Realm Control. And this peach pit and the corresponding secret law do not need these prerequisites, it is the traditional inheritance method of the outside world.

For example, if Yang Chengong lost his Realm Control Treasure, Ding Qi could teach him this peach pit, including the set of secret methods he had created, and then replace the original inheritance of the Changcheng Blessed Land.

Ding Qi's purpose in doing this, of course, was not to use this to seek the blessed land, it was just an attempt in cultivation, and it was also an exploration of cultivating the secret method outside the square to a higher realm. Ding Qi spent three months in the fixed realm, running his heart plate to deduce the world, in fact, he was refining this peach pit, at least he succeeded in the first step.

Looking at the peach pit in his hand, Ding Qi felt that it was almost meaningful to the real treasure of the control world, and this feeling was indescribable. The treasures of the realm control that Ding Qi has seen are actually artifacts, but this peach pit is not, and Ding Qi has not yet had the ability to refine an artifact.

It is more like a more useful sub-weapon specially designed for the cultivation of the blessed land, and in some ways it can even replace the treasure of the realm control, and with the exclusive secret method inheritance, it can only be used in this outer world. You may not need it right now, but other worlds need it!

For example, if the legendary Xiaoyang Kingdom really found this outside world, but could not find the treasure of the control world, and did not get its secret method inheritance, then how could the Fang Outside Alliance explore and develop? The same can be done.

At dawn, Ding Qi put away the peach pit and walked back to the courtyard where Yang Chengong and the others lived amid the sound of chickens. For him, the time spent refining the peach pit was not one night, but a real three months, and it also consumed three months of longevity. When Ding Qi walked into the courtyard gate, Ma Xiao also happened to come out of the house, only to see her exclaim in surprise, "Who are you?"
