Su Chen shook his head, all he knew about this planet came from the few exchanges he had with Maizi after arriving on this planet, as well as his cautious various observations.

"Senior Sister" couldn't hide her excitement, and said to Su Chen excitedly: "I'll give you a hint." Do you know where this planet once gave birth to the ancestor of the most powerful and mysterious civilization in the history of the Galactic Federation, the Sereva civilization? ”

Su Chen was a little confused when he heard this name at first, but then he suddenly remembered that when he was frantically absorbing all kinds of knowledge on a small spaceship, he had paid attention to this civilization.

The Sereva civilization is a very strange existence, and it has left a strong mark on the history of the Galactic Federation.

Today, among the dominant intelligent races on the seven main planets of the Star Federation Center, about a quarter to one-third of the races insist that their race is a descendant of the Sereva civilization. Some of them really have nothing to do with the direct descendants of the Sereva civilization, and they seem to have taken a great advantage when they get the name of the collateral descendants, and they often show off to others.

But there are many mysteries about this civilization, and the most mysterious of them is that, like its sudden rise without warning, it suddenly disappeared after two thousand years.

It disappeared so suddenly, that even on many of the planets it once ruled over, there was no trace of scientific research or archaeological discoveries for future generations.

It's as if all of a sudden, by the hand of some fate in the dark, it's as easy as erasing the wrong pencil handwriting with an eraser.

However, when it came to the ancestors of the Sereva civilization, Su Chen really had a black eye.

He hadn't read any records of this civilization.

The information he saw said that this civilization appeared and disappeared suddenly. It was because of this that he felt that this civilization was very similar to a short-lived city-state civilization that had appeared on the Blue Star. It was because of this intimacy that he made up a bunch of information about this civilization.

In my memory, this short-lived Sereva civilization was indeed an era of harmonious coexistence between industrial technology civilization and spiritual civilization.

But what do the ancestors of this civilization refer to?

"Senior sister" saw Su Chen pondering and recalling for a while, and finally shook his head, knowing that he really couldn't answer, so he simply didn't sell it:

"The ancestors of the Sereva civilization are the Kututro people!"

"Cool Tutro?"

"Yes, yes! Got an impression? ”

"No ......"

Su Chen was very ashamed, what he studied was actually very unsystematic, on the one hand, time did not allow, and on the other hand, he was actually a little lazy.

For subjects like "History of the Civilization of the Galaxy Federation", Su Chen felt that it was unlikely to be used immediately, so he just flipped through it casually and let it go.

In fact, as far as his current memory is concerned, as long as he reads it carefully, where is the "senior sister" still used to guide him so painstakingly?

Alas! Sure enough, the book is hated less when it is used!

Before Su Chen finished sighing, Senior Sister had already put a slender white finger on his forehead:

"You stupid! How much water did Master put in to let you get away with graduation! ”

From this sentence, Su Chen suddenly knew who the master in the mouth of the "senior sister" was.

However, this made him even more suspicious. As far as he knew, his grandfather, who directly taught him the "Rejuvenation Technique" and the talisman technique and the formation spell, did not accept any apprentices except himself.

And "Senior Sister" used the word "graduation" again, so the only candidate for the master in her mouth was the old-fashioned and old-fashioned, serious and demanding old man in the Yulong Mountain Martial Arts Hall!

And this point is also more consistent with the fact that he is called a "little junior brother".

Because, I grew up with my grandfather since I was a child, and my grandfather began to teach me some Taoist basics very early. If it's from my grandfather's side, I have to be a big brother!

Unless, this "senior sister" is actually a disciple of my grandfather's senior brother!

But looking at her remarks, it doesn't look like it at all!

But......

The old man of the Royal Dragon Mountain Martial Arts Hall is obviously an ordinary person. Although his skills are too strong to speak, there is no spiritual power fluctuation in his body at all!

And when the sleeping beast infiltrated the martial arts hall at that time, didn't the old man also take the illusion of the sleeping beast seriously, thinking that she was just an ordinary tabby cat? When the sleeping beast went to rub the pillar of light of Su Chen's Wood Spirit Bead every night, didn't the old man always sleep sweetly and always snore?

Could it be that the old man has always been a hidden spiritual cultivator?

If this guess is correct, then Su Chen at least doesn't have to worry about the old man's safety in the drastic changes in heaven and earth.

Regardless of the materials of the Imperial Dragon Mountain Martial Arts Hall, since the old man can teach an apprentice of the level of "Senior Sister", he can only be stronger, not weaker!

What's more, judging from the fact that the "senior sister" identified him as a "little junior brother" from the beginning, she should have met the old man! This shows that the old man is not only not in any danger, but is more likely to be in a safe place to taste the delicious food!

These things seemed to be a lot, but in Su Chen's mind, it was just like lightning, and he thought about these many thoughts in an instant, and also came to these conclusions, and then his mood instantly improved a lot, and the depression of being despised by the "senior sister" disappeared in an instant.

"I haven't learned this, but Master taught me for three months and learned some basic kung fu."

"Uh...... What a defeat for you! Even the people of Kututro don't know! Then you always know why the Galaxy Federation is called the Galaxy Federation, right? ”

"Well, the Galaxy Federation is called the Galaxy Federation, because the star fields of these planets are connected by the members of the Federation, and it is a magnificent galaxy!"

"At this level, you can barely pass it. In fact, there is a secret here that only a few people know. ”

"Oh?"

"Senior sister" smiled proudly, ready to sell a pass. Her smile was bright and fresh, like a flower with morning dew suddenly blooming in the morning light, turning her delicate face into brilliance in an instant.

Su Chen almost straightened his eyes, quickly shook his head, threw aside the messy thoughts, and looked at the eyes of the "senior sister" seriously, waiting to listen to her literacy class.

"Senior Sister" couldn't help but laugh again when she saw Su Chen's appearance, she felt that this little junior brother was simply too interesting, and with him, it seemed that she could inadvertently pick up a lot of jokes.

"Senior Sister" laughed for a while, finally calmed down, and explained to Su Chen in detail.

It turns out that the name of the Galaxy Federation is really not just due to the fact that many members of the Galaxy Federation form a magnificent galaxy.

In fact, it has a meaning that few people know about, but it is very significant.
