(Because I wrote two chapters,So I'll update two chapters.,4000 words, don't complain that I take the setting to inject water.233The introduction of the dragon family is related to the plot later.,In fact, it's not a water injection setting)

Shi Leiyin is a person with a somewhat divergent thinking, and after inheriting his memory and seeing the powerful creatures of the ancient era, he instinctively carried out relevant memory retrieval.

Although the fruit of original sin is mainly based on the inheritance of memories, it still contains a lot of memories of ancient times, and the reason for this is because although there was an era of mass extinction in ancient times, there are still many creatures that have survived and lived to this day.

Among them, it can be said that the dragon clan has survived the most.

This dragon clan does not only refer to the dragon clan from Dragon Island on the mainland.

Strictly speaking, the dragons on Dragon Island are only descendants of a certain weak branch of the dragons in ancient times.

The dragons of antiquity were divided into two large groups, the wise dragons and the non-intelligent dragons.

The Wisdom Dragons are very similar to the Western Dragons that Shi Leiyin is familiar with, with thick hind limbs that walk upright like humans, and forelimbs that are more used to do hand-like work, although they can fly with pure wings, they use more magical elements to assist themselves in achieving flight goals. The use of magic and social settlements are a characteristic of the Wise Dragons.

The origin of the Wisdom Dragon Clan is not introduced in the inheritance of the Fruit of Original Sin, and at the same time, there is no inheritance memory of the Wisdom Dragon Clan in the Fruit of Original Sin, and it is known from the inheritance memory of other creatures of the same era, Shi Lei Yin, that is because the strength of the Wisdom Dragon Clan is too strong, and the Fruit of Original Sin cannot be copied to obtain even a deteriorated inheritance memory.

However, from the inheritance memory of other creatures, Shi Leiyin can still get the relevant introduction of the wisdom dragon family.

The Wisdom Dragons are divided into ten different small types according to the magic used, but due to the fertility problems caused by their strength, the total number of Wisdom Dragons did not exceed 1,000 even in the most glorious period when they almost ruled the entire world. And because of the wisdom dragon clan's participation in the Three Realms War that led to the advent of the mass extinction period. In the end, only seventeen wise dragons survived, and three of them, representing different kinds of last survivors, broke the boundaries of the world and left this world. As a result, there are only three male dragons and eleven female dragons in the wisdom dragon clan still living in this world. However, this inheritance memory is more than 300,000 years ago, and after such a long time has passed, it is unknown how many wise dragons still have them. Of course, according to the fact that there are no legends or news of the wisdom dragon clan on the continent now, the number of wisdom dragons has obviously not recovered enough to reign on the continent again.

It is worth mentioning that there is a very peculiar phenomenon of the wisdom dragon clan, that is, the strength of the female wisdom dragon clan is far stronger than that of the male, and the combat power of a female wisdom dragon clan is equivalent to at least a hundred male wisdom dragons. This is also why the number of females in the surviving intelligent dragons is much greater than the number of males.

Of course, even the weakest wisdom dragon clan also has a strength far beyond the current ninth order and twenty levels, there was no so-called hierarchy division in the world at that time, if you have to make a reference, that is, the weakest wisdom dragon clan at that time also had enough strength to fight and kill the other two realms - the god king or demon king level in the god realm and the demon realm alone. This is also the reason why the Wisdom Dragon Clan participated in the Three Realms War with less than 1,000 members, but the two worlds of gods and demons that could fight had to stop fighting and join forces to fight against the Wisdom Dragon Clan. Regarding the War of the Three Realms, there is not much mention in the inheritance memory, that is, the battle between the two worlds of gods and demons, and the result is that it hits this world. Then he accidentally affected a young dragon of the Wisdom Dragons. So under the leadership of a certain female dragon of the Wisdom Dragon Clan, the entire Wisdom Dragon Clan was dispatched, not only exterminating the power of the gods and demons in this world, but also turning the gods and demons upside down. In the end, the two races were forced to join forces to create the Age of Mass Extinction, and most of the intelligent dragons were exterminated. It's just that although the Wisdom Dragon Clan is almost wiped out, the strongest female dragons are safe and sound, which also makes the Protoss and the Demon Clan dare not easily stir up trouble in this world.

Although the wisdom dragon clan is strong, its fertility is also low, so even if there are survivors, it has nothing to do with the current dragon clan.

Related to the current dragon clan is another branch of the ancient dragon clan, the non-intelligent dragon clan.

Non-intelligent dragons are a collective term for the less intelligent dragons of the Elder Dragons. Not only are they very different in size, but they also have great differences in their habits and intelligence.

One of them, the Dixing Dragons, has similar group habits to the Wisdom Dragons, but this group life is similar to that of cattle and sheep, and only relies on a large number of groups to protect the population itself. This branch of the Earth Walking Dragons was fortunate to have escaped the mass extinction period and have multiplied to this day, and after survival and evolution, they formed the dragon population on the Dragon Island today. Among them, the atavistic dragon king of the earth, Terrifu, is the dragon king of the current Dragon Island. Other Earthwalkers have evolved into several other bipedal dragon species. The Gobit Earth Dragon and the Dimeter Wyvern are the dragons that appear the most on the continent.

In addition to this group of earth-walking dragons who evolved and bred a large number of groups, there are also some solitary non-intelligent dragons who have also survived.

Because of the mass extinction relationship, these solitary non-intelligent dragons are sometimes unable to find a mate of the same race, and they are sometimes driven by the urge to reproduce, and they sometimes have some special relationships with other creatures that survived the mass extinction, and the result of these circumstances is the emergence of the ancient wurms today. And those who have found a mate of the same race and maintained the purity of their bloodline to this day are called ancient dragons.

The dragons of Dragon Island only have four limbs, and that's because their ancestors, the Earth Walking Dragons, were low, non-intelligent dragons who walked on all fours. The current Dragon Island Dragon Clan is only about the fifth order and the fourteenth level when it reaches adulthood, and even the atavistic Dragon King Tai Ruifu has not broken through the limit of the ninth order and the twentieth level. This strength was a stronger prey in ancient times, while other Dragon Island dragons and food were basically the same.

Ancient wurms also only have four limbs, and although many of them have strong flying abilities, their wings are all evolved from forelimbs or simply extended from forelimbs like bats. That's because although the ancient wurm has some of the bloodline of other ancient dragons, the other half of the bloodline comes from other creatures, although these creatures may not be weaker than ancient dragons.

The most important feature of the ancient dragon is that it has four limbs and a pair of wings, which is the so-called six-limbed body, just like the intelligent dragons.

This peculiar six-limbed body structure is characteristic of the top creatures of antiquity. This means that the ancient dragon has a strength that is almost close to that of the ancient wisdom dragons. Moreover, because they are so intelligent that they cannot use magic, their physical bodies are stronger than those of the ancient wise dragons. However, also because of their low intelligence, ancient dragons are more likely to be hunted by creatures with lower strength than themselves and rely on their intelligence. The members of the gods and demons can easily hunt the former in the face of the ancient dragon and the wisdom dragon clan of the same strength, but they will definitely not be able to harm the latter, in fact, if they encounter the latter, they will not even be able to escape.
