In front of Lu Yu was a huge and amazing crater, and when he looked up, he found that the vertical depth of this crater was at least a thousand meters!

There are also thousands of kilometers of craters on the moon?

At least the positive glossy surface of the moon has never been found on such a scale!

This crater is the largest crater ever discovered!

Suddenly, Lu Yu felt that he had stepped on a hard object, and when he looked down, he instantly broke out in a cold sweat!

Bones!

Miserable white bones!

Not the white bones of strange creatures, but ...... Human skulls!

The white and dusty human skull began to gurgle and roll forward as Lu Yu raised his feet in horror.

Slowly, it rolled into a continuous sea of white.

Lu Yu's pupils shrank suddenly, and he looked at the white sea in front of him in disbelief.

This white ocean is nothing else, it is a dense and endless white bone!

And all of them have the characteristics of human bones!

Human skull, human leg bone, human pelvic bone......

Even though some of the bones had bone spurs, some were pure black, and some looked strange, Lu Yu was sure that most of these sea of bones that covered the bottom of the entire circular valley were human bones!

Lu Yu frowned, slowly walked in the sea of white bones, holding a hint of expectation, and kept looking at the bones in all directions.

But when he walked to the other side of the canyon and crossed this sea of bones, his hopes were completely gone!

The bones here are all human bones!

There is no exception!

Here, it is a forbidden place of death for human beings, and it is a Shura field for human beings!

Lu Yu bent down with great effort, picked up the iron piece next to the white bone at his feet, wiped off the dust on the iron piece, and found that the iron piece was engraved with several words similar to Blue Star Kyushu, which were faintly recognizable.

"Blue Star Federation...... Shangri-La Empire...... Third Fleet...... Vanguard Fleet ......"

Lu Yu looked at these words as if he had been struck by lightning, and involuntarily took two steps back, looking at the sea of bones in front of him in shock.

Is it here...... Are they all people of Shangri-La civilization?

What really happened on the moon?

The black dragon, the bronze coffin, and the Shangri-La Shura Field here, made Lu Yu feel as if he had touched an indescribable horror, and he walked in the sea of bones again, finding more and more identity iron plates.

"Blue Star Federation...... Shangri-La Empire...... Third Fleet...... Members of the frigate. ”

"Blue Star Federation...... Shangri-La Empire...... Third Fleet...... Royal Guard. ”

All identity iron cards have a key message, that is, the Blue Star Federation!

Lu Yu had never heard this word, and the prophet of the Atlantean civilization had never mentioned it, could it be that in the history of the young planet Blue Star, there was a super civilization that stepped far away from the galaxy?

The Blue Star Federation, at the very least, must unite all the civilizations and forces of the Blue Star to create a force with the prefix of the planet's name!

However, even with such a planetary force, countless lives and blood were poured on the moon.

What is the past of Blue Star?

Lu Yu suddenly saw that in the southeast corner of the Sea of Bone, there was a slender object erected high.

When he got closer, he saw a flag quietly planted in the lunar soil, surrounded by human bones.

But the bones were all in the same position, and their hand bones were reaching out towards the flag, as if trying to keep it from falling.

Although they have all died on the vast and desolate lunar soil, their faith is as if they are not dead, so that this banner has gone through countless years and cosmic changes, and still stands tall and immortal, like an immortal giant or an indomitable ant.

Lu Yu's gaze slowly moved upward, and finally fixed on the flag.

This flag depicts a blue planet and a group of humans of different colors and appearances.

The Azure Planet is at the very center, and humans are dressed in all kinds of armor and weapons, piloting space warships around it.

At the bottom, there are also eight blue star characters, which are divided into four groups, each of which is a different font.

Two Kyushu fonts, two West Continent fonts, two ocean characters, and two Lie Continent characters.

Lu Yu guessed that this was the text of the four ancient civilizations, and when these eight words were combined, even his hands and feet trembled when he saw it.

Eight words, a piece of history, a history that may have disappeared.

Blue Star Federation, long live humanity.

These eight words, on the flag, face the vast starry sky with the flag.

Lu Yu took a deep breath, endured his passionate emotions, and slowly stretched out his hand to the flag, pulled it out and carried it on his back.

The moment the flag was pulled out, the surrounding bones who still wanted to keep the flag alive after the vast years fell to the ground one after another.

It's as if their mission has been accomplished and they can rest in peace.

"Blue Star Federation, long live the human race." Lu Yu carried the banner of the Blue Star Federation, and finally took a deep look at the white bones on the ground, and bent down slightly to whisper to these ancient humans: "Civilization is immortal, Blue Star is immortal, if I can live to the end, I want to see it...... The real world. ”

After Lu Yu did all this, he stood next to the crater, his knees slightly bent and jumped hard, and slowly rose to the outside of the crater.

After leaving the crater, he searched for a long time before he found the traces of the lunar module again, and then continued to track.

But now, Lu Yu has raised his vigilance to the highest point, it is too weird here, and he has to be cautious to the limit.

Two hours later, the traces of the lunar module finally came to an abrupt end, and Lu Yu also stopped there, he looked up at the glorious and vast ancient palace in front of him, especially the carved patterns at the gate of the main hall of the ancient palace, which deeply attracted his attention.

In this pattern, the mountains and rivers are the base, the sun, moon and stars are shrouded in it, and in the middle stands a huge mountain peak made up of multiple peaks.

The whole color of the pattern is bright yellow, and Lu Yu actually felt inexplicably friendly to this pattern.

It's as if I have a bond with this pattern that transcends time and space.

"That's what it is...... That Shangri-La base on the moon? ”

Lu Yu had seen the symbolic patterns of the four ancient civilizations in the Atlantis base at the bottom of the sea, and the pattern of mountains, rivers, sun and moon filled with bright yellow in front of him was the pattern of the Shangri-La civilization, one of the four ancient civilizations!

There is a heart to pick flowers and flowers do not bloom, and there is no intention to plant willows and willows.

Lu Yu landed on the moon this time to find the Shangri-La base, but he didn't expect to find it by mistake with the missing lunar module!

Song Yi said that there is only one Shangri-La base on the moon, so this one in front of him must be what Lu Yu is looking for!

But now standing next to the Shangri-La base, Lu Yu is in trouble.
