In terms of strength, now the black skin has surpassed the bald head, and in terms of wisdom, he is still far behind, but several ancestors know some words, and they will usually teach the next generation, and the black skin is not illiterate.

"Bald, you send a few dinosaurs who are proficient in writing to get close to those sword tigers, be sure to understand their language as soon as possible, and then learn more information from their mouths, and be sure to find a way to pry their mouths open and let them reveal more about the sword tigers and other races." Zhang Jun then said to the bald man.

The bald man nodded and said, "Okay, I will definitely complete this task as soon as possible." ”

Then Zhang Jun thought of another means, that is, the matter of the reconnaissance team, and immediately said to Fei Ge: "Fei Ge, you have one more task, you ask He Meng to organize a temporary reconnaissance team to infiltrate Central Asia to find out the living conditions of sword tigers and other creatures, mainly to find out their numbers, distribution, and sphere of influence, all of which must be drawn into a map, bring the flying dragon who understands the text, let them record it, and we will study it in detail when they come back." ”

"Yes, I will organize a few squads and let them take turns to enter Central Asia, try to get more details, and come back to report to the big leader." Fei Ge commanded.

In the past hundred years or so, the flying dragons have also occasionally entered the Central Asian region, but they are all for the purpose of ordinary reconnaissance, to prevent other creatures from entering the area west of the Red Sea, mainly for the sword tiger, this time it is necessary to carry out systematic, large-scale, long-distance reconnaissance, and find out all the information of the other party in detail, it must be a large area, all-round, so as to know oneself and the other.

After arranging this matter, Zhang Jun began to sit around the fire with several ancestors, together with the leaders, village owners, and captains, and began to discuss the specific matters that need to be implemented in the village in the recent period, including breeding, defense, law enforcement, young dragon raising, combat readiness, training, reconnaissance, construction, and other matters.

After the specific work arrangement was implemented, Zhang Jun began to announce one thing, which was a decision he made after thinking about it for a long time, and it was about the problem of time notation, that is, now the dinosaur clan needs to start using the year, month, minute, hour, minute, second, and specific time to calculate the progress of time.

In the past, they only knew the year and the day, but now they have to distinguish the time period in detail, but the hours, minutes, and seconds are difficult to calculate, so for the time being, they can only calculate the time according to the hour, and it is not so accurate.

Zhang Jun has been discussing this matter with several ancestors for a while, and the most important thing for him now is to raise the question about the first year, which year the so-called first year is the year of the zero year of AD.

In the end, the result of everyone's discussion basically agreed with Zhang Jun's proposal, that is, from the year when Zhang Jun found the Flying Dragon, the Flying Dragon, and the great fusion of dinosaurs, with that year as the base point, as the zero year of AD, the subsequent years have increased year by year, so the current year has reached 105 AD.

Zhang Jun knows that the current social development process will definitely be much faster than the history of human development, once the dinosaur race is born with a more advanced civilization, the sword tiger and humans, and other races will speed up social progress through learning, so the original barbaric era 10,000 years ago will definitely not last 10,000 years, and the feudal society and capitalist social form will definitely come in advance.

Therefore, Zhang Jun thinks that there is no need to calculate 10,000 years after 10,000 years as AD 0 according to the algorithm of the previous life, and now it can be calculated like this, and Zhang Jun cannot accurately grasp which year AD 0 is, he only roughly estimates that it is about 10,000 AD years ago.

"A.D. 105, this is our current year, well, now we have a record of the year, whatever major events happen in the future, we can record them in the year table, then we know what happened in the past, what time it is, this is great." He Meng felt very practical about this vintage recording method and said with a little excitement.

Everyone also feels very reasonable about the notation of the Common Era, from which the dinosaur clan can record historical events and future events in a certain time period of the Common Era, so that future generations can extract useful time information from it.

Zhang Jun then instructed Xiao Al again: "Little El, you have to grasp a job now, that is, let your historical historians record the historical time in more detail, and they can't be as rough as before." ”

"For example, today's battles, how they were fought, including the occurrence, time, place, arrangement of troops, attack, collection of troops, specific to the detachments going into battle, and how to destroy the enemy, must be recorded in detail, and the historical experience of these battles will have a great impact on our future generations in dealing with the enemy, and this matter is very important, and in the future we can compile a book of the battles that have taken place in the past, circulate them, and let the soldiers read them, so that they can remember the battles that have taken place in history and how they were conducted." Zhang Jun then said solemnly.

"I understand, leave this matter to me to deal with, the bald man is too tired, he used to do a lot of things about words alone, and now we should also share a part." Little Al commanded.

Previously, Bald was in charge of all the work related to writing, but now he was no longer able to do it, so Zhang Jun gradually dispersed the powers of several ancestors, Bald was in charge of politics and also the military, Heipi was in charge of law enforcement, Qili was in charge of finance and material distribution, Da Al was in charge of construction, Little El was in charge of young dragon training, and Feige was in charge of training and defense.

Basically, each performs his own duties, and in the future, Zhang Jun is ready to hand over the cultural affairs to Xiao Al to be responsible, so that the baldness will be much easier.

Regarding the historical record, Zhang Jun believes that this is a very important work, in the previous Chinese historical records, there is a great lack of military aspects, that is, the description of the battle is too rough, just a simple description of the battle process, and does not carefully record the specific command, movement, implementation of the details of the battle, including the details of weapons and equipment, so Zhang Jun is ready to change this, so that the record becomes more detailed and accurate, so as to play a greater educational significance for future generations.

Then the dinosaur group returned to Longzhai, and one of the key points in the work after that was to master the language of the black tiger as soon as possible, and to get more things out of his mouth, in order to complete this work as soon as possible, Zhang Jun let Bald Head and Big Al personally participate in it, their language skills are stronger.

After about half a year, Bald and Little Al were able to communicate with Black Tiger in a verbal manner, and their men could understand what Black Tiger was basically saying, which was achieved through a long period of time with Black Tiger.

Then Bald and Little Al began to interrogate the Black Tiger, at first the Black Tiger did not plan to confess anything, but after a long period of soft grinding and hard foaming, as well as the threat of torture, the Black Tiger slowly confessed some things.

The Black Tiger told the bald head that they came from the sea east of the desert, where there was a huge tribe of sword tigers, and there were thousands of sword tigers in the tribe, an astonishing number, and they were only a small part of them, and they were sent by the patriarch to explore the way.

From the mouth of the black tiger, Zhang Jun learned that the sword tiger tribe has been the dominant one in the Middle East and Central Asia in the past hundred years, but in recent years, many humans have migrated from East Asia, North Asia, and South Asia, and their number is more, and in Europe, there are more intelligent creatures, in addition to humans, there are pigs and wolves, giant rats, a variety of intelligent creatures, they gradually stretched their claws to the Asian region, because there is fierce competition in their living environment, fierce racial strife, and they must expand their territory to other regions.

In addition to these land creatures, according to the Black Tiger, the Sword Tiger tribe is often harassed by giant whales from the ocean, and these races that once lived in the sea are no longer satisfied with their habitat and have begun to extend their claws to the land.

This is the first time Zhang Jun has heard rumors about the giant whale clan, because he has always thought that only land creatures can evolve intelligence, but this time it is the first time he has heard that a sea creature has also evolved wisdom, which makes him feel very shocked and has subverted his previous cognition.

Zhang Jun still didn't understand, in fact, all of this was caused by the explosion of the spacecraft, if they hadn't entered the space-time temple back then and opened too many space doors, the alien matter in the space would not have easily scattered on the earth.

As a result of that big bang, the genes of many animals have mutated, some of them have advanced and become wise, some of them have become stronger, and some of them have changed their body shape, which is why they have today's chaotic situation.

From the mouth of the black tiger, Zhang Jun also knows that there are more than 20 kinds of intelligent creatures in Central Asia, among which the sword tiger and humans are the two most powerful, and the wolf and pig tribes from Europe are trying to invade Central Asia, so the pattern of Central Asia is very chaotic, the competition is very fierce, and the living environment in the future will be even worse.

Therefore, the patriarch of the Sword Tiger living in Israel decided to send people across the great desert and into the southwest region to find more habitats, if they can find a vast land, then they can find a safe place to live, and they do not have to participate in the great strife in Central Asia, so that their children and grandchildren can have a more peaceful living environment.

But the sword tiger patriarch didn't think about it, in fact, in the northeast of Africa, there is also a powerful dinosaur race, which is breeding on the oasis and on both sides of the Nile River, and their civilization has surpassed that of any race in other regions, but their number is not comparable to that of humans and sword tigers.

Zhang Jun has learned that the scale of human beings and sword tigers has long exceeded the dinosaur family, human beings have lived in large-scale groups thousands of years ago, and human tribes are all over the country in Asia and Europe, but in Central Asia, it has always been the territory of the sword tiger, so Zhang Jun did not find more humans.

This encounter with the black tiger made Zhang Jun get more information, he knew that he had stayed in Egypt for the past hundred years, and he had become a little lonely, and the collision between civilizations was now inevitable, and it was impossible for him to be in a safe corner.

Zhang Jun secretly felt that the hundred years of peace and tranquility of the dinosaur race were coming to an end, and an unprecedented race competition was about to begin, and soon, other races would stretch their claws to the relatively quiet African region, and the threats they faced were unprecedentedly increased, and the world pattern was about to take shape.
