A moment later, Su Heng came to the most central part of the mini continent, where the massive building groups covered by the forbidden groups were located. This massive building community was extremely tall and located on the plain. Any building, portal or one floor was tens of meters high, often with 70, 80 or 100 floors. There were streets, squares and even landscape vegetation between the buildings.

At a glance, it is similar to the modern metropolis of the earth full of high-rise buildings.

However, this is an urban community that has been magnified many times. Most of human high-rise buildings have only about three meters on the first floor, and each floor here is tens of meters.

It's like a giant group of high-rise buildings and metropolises.

It is not surprising, for example, that in the present Tianyuan mainland, the dominant ethnic groups such as the Tianyin, Fuguang and Lingfeng ethnic groups, and the adult ethnic groups are often more than ten meters tall or 20 or 30 meters long. Other original intelligent ethnic groups in the Youying mainland also have different appearance and uncertain height and body shape.

Whether the Tianyuan continent or the Youying continent, the surviving intelligent ethnic groups are all members of the Federation of ancient civilizations left behind after the collapse of ancient civilizations. It is only because the inheritance of knowledge and other systems is broken that their respective clusters develop again.

The whole urban community was protected by a mottled layer of space. When Su Heng tried to enter, he found that he had just touched the layer of space and was thrown out.

Smiling and shaking his head, he grabbed the earth book to integrate the nearby world. After a few breaths, Su Heng smoothly entered the huge city.

Standing high in the air, Su Heng's perception spread. At the next moment, Su Heng stood in front of a huge building with more than 70 floors and more than 40 meters on each floor. The architectural style of this building is obviously different from that of human beings. Regardless of the style, he is most concerned about the plaque hanging on the first floor of the building, which is written with seven characters "Xinghe federal Civilization Museum".

After seeing it, he naturally understood the meaning of these words.

This is the ancient civilization, the civilization calling itself the star Federation, and its own library.

"Although the major intelligent ethnic groups have also found and collected a lot of data related to ancient civilization from various sites, how the ancient civilization was born, what changes and annihilations it encountered, and how the birth and origin of ethnic groups on the mainland appeared... All these are still very vague."

"If there are enough records in this Civilization Museum, it is estimated that we can find out everything. This is a great harvest."

A few thoughts flashed through his mind, and Su Heng escaped into the huge civilization hall.

……………………

A few hours passed by. On the seventh floor of the Civilization Museum, Su Heng was shocked when he put down a huge jade book.

The volumes of jade books on this floor record the historical records of the ancient civilization Xinghe Federation.

Ancient civilization originated on the planet where the Tianyuan continent was located. The original federal subject was led by the source family. They claimed that the planet under their feet was the source star and themselves were the source family.

Hundreds of thousands of abyss years ago, Yuanzu stepped into the space age and began to develop outward with the origin star as its base camp. They met life planets and different intelligent groups to see and conquer.

The process of seeing and conquering includes peaceful annexation and blood and fire killing.

Dozens of ethnic groups currently living in Tianyuan continent? No matter Tianyin clan, Lingfeng clan, Xiyun clan, Xingye clan and so on, they are all the younger brothers incorporated by the source clan when they conquered the starry sky.

Yuanzu conquered the road of space and created the star Federation. At its peak, it only talked about individual combat power. Yuanshi was everywhere, and annihilation was like a dog.

Their process of unifying the stars can be called smooth. After integrating different planets and civilizations, they will improve and develop themselves, and almost unify the galaxy.

By the way, when reading here, after several comparisons, Su Heng determined that the galaxy called by the source family is the Milky Way claimed by the earth people.

But when the original race swept the galaxy, on the other side of the earth? This is the era before hundreds of thousands of abyss years. The earth year is equivalent to millions of years ago. The earth millions of years ago is too primitive. Maybe the source family has found the earth in that process, but they don't bother to pay attention to it.

Based on the origin star, the source family formed a huge coalition with conquered intelligent groups on the planet, sweeping the peak of the galaxy, but suddenly encountered a devastating disaster, the star swallowing family.

According to the name, the star swallowing clan knows the horror of this clan. Each of them exists to devour all material bodies visible in space, stars, planets, satellites and all kinds of small celestial bodies. Whether there is aura fluctuation or life, the star swallowing clan is to see stars, destroy stars and swallow stars.

No matter whether the source race has killed a sea of blood when conquering the little brother race in the process of conquering the galaxy, their means are generally mild. Merging civilizations also allows the little brother race to exist and enter the Federation for development.

But swallowing the stars, see a planet destroy one, leave no room.

The final collapse of the Federation was caused by the war with the star swallowing clan. Until the end, the Star River Federation also lost countless territories and countless life planets. Finally, it retreated to the small galaxy where the origin star was located with all its main forces.

The origin star of the abyss continent, and various broken forbidden groups in inner and outer space, were left over from the war with the star swallowing clan, and so were the deep-sea natural disasters.

Blade wing family? The sabre wing clan is actually a biological weapon developed by the big brother of the federal endogenous clan. It is specially used to deal with the swallowing Xing clan. Their clan can be promoted and strengthened by swallowing life. The original purpose is to target the swallowing Xing clan and have a miraculous effect on the swallowing Xing clan

Unfortunately, there were successes and failures in scientific research. The first World War broke out before perfect results were developed.

At present, the sword wing clan, the civilization destroyer feared by the abyss alliance, was originally created to guard the union.

Therefore, the emergence of the Daoyi clan is so wonderful. It is the intelligent ethnic group in the Youying continent that was dug out and released from an ancient site, which led to the destruction of dozens of ethnic groups in the Youying continent.

That ancient site was where the Yuanzu scientific research site was.

In the final World War I, the origin star array prohibition defense system was torn apart, with countless deaths and injuries. All continents were isolated by broken prohibition groups. The three dominant ethnic groups in the mainland, such as Tianyin, Lingfeng and Fuguang, were only the blood left by the younger brother ethnic groups brought back by the source ethnic group.

In that war, almost all the adults and wise fell. They fought at the forefront, leaving behind groups of fiery children in the ethnic group, who were protected in various array forbidden groups.

Of course, since it is a fire, every array prohibition group protecting fire also has a complete knowledge system and growth resources for children's development. Unfortunately, similar array prohibition was also affected and damaged in the final World War I

After that war, the star swallowing clan seems to have been destroyed? Otherwise, the origin star should not exist?

The infants of Tianyin, Fuguang, Lingfeng and other ethnic groups have developed to the current situation one by one after more than 100000 years under the condition of incomplete knowledge system and many losses of resources.

Rebuild civilization from the ruins.

After reading all this, Su Heng suddenly realized why the planet where the abyss continent is located has such terrible and prosperous resources, and why there are so many different intelligent groups on a planet.

This is the era when the source nation conquered the galaxy and swept countless life planets. Before the last war, it gathered the resources and treasures of countless planets. Those who brought back the origin star also brought back countless ethnic groups.
