Qiu He led the way in front with a flashlight, and after walking for a long time, he came to an empty cave.

The first thing that catches your eye is a huge tree-like structure in the middle of the cave, which emits a dazzling white light that illuminates the entire cave.

"Boom!"

Jin seemed interested in the Light Tree and rushed towards the Light Tree.

Qiu He's hand quickly stretched out at this time, grabbed Xiao Jin's tail, and stopped it from moving.

The excitement from Xiao Jin, Qiu He had some guesses about the identity of this 'light tree', but he still told Xiao Jin not to move.

Everything, wait until the situation is clarified.

The rock walls around the cave are different from the rock walls of the previous passage, showing a bright red color, and there are some murals and ancient texts carved on the rock face, which may be a description of the blank 100 years.

Robin stepped forward, checked it a little, and then said quite firmly, "It's the same material as the historical text." ”

It is precisely because of this stone that the murals and texts engraved on it can survive 800 years and can still be preserved in good condition until now.

The rock wall is covered with a thick layer of ash, and it is still unclear what is painted on it, but the dust here is not worth mentioning compared to the dust in the passage outside, and it is thought that it was cleaned twenty years ago.

"Let's wipe it first."

Qiu He sighed and took out a bucket full of water and a towel.

With such a large rock wall, this cleaning work is not very easy.

Luckily, Robin's ability to grow flowers and fruits is perfect for cleaning, no matter where it is, even if it's a cliff at a 90-degree angle, she can grow hands.

Countless hands cooperated with the work, and the cleaning work was done quite smoothly and efficiently, and soon the place was completely cleared, and under the dazzling white light, the red rock wall took on a bright red color, just like the things it recorded.

The petroglyphs are not a single piece, but are arranged one by one in chronological order, and each painting is accompanied by some text descriptions, so that each painting is presented as an independent story.

First of all, the first one is a ball with a tree drawn on it, and the tree looks almost exactly like the 'light tree' in the middle of the cave.

Just looking at this mural, Qiu He roughly guessed the meaning of what the ancients wanted to express, but if you want to be sure, you still need to cooperate with the text explanation below the mural.

So Qiu He looked at Robin who was standing aside, ancient words, can only rely on Robin to translate.

However, at this time, Robin was staring at the ancient text under the mural, his mouth wide open, with a shocked look, unable to speak for a long time.

Seeing this, Qiu He stretched out his hand and shook it in front of Robin's eyes, and said, "What's wrong?" Don't be surprised, translate it, historian. ”

Robin closed his mouth, was silent for a moment, and said, "This sphere refers to another planet far away from the planet under our feet, and the tree above it is a sacred tree worshipped by the people of that planet, and this sacred tree can give people all kinds of magical powers. ”

Robin was shocked because she knew for the first time that there were other planets in the starry sky besides the planet beneath their feet.

And the sacred tree on the mural, it can be guessed from the ability that this should be the source of the devil fruit.

"What! There are other planets! ”

Perona, who was floating on the side, listened to Robin's explanation, couldn't help covering her mouth, and exclaimed in shock.

Only Qiu He did not show the slightest expression of surprise on his face, after all, he had a wealth of knowledge in his previous life, and he had personally experienced the crossing, Qiu He was not surprised by this.

Robin looked at Qiu He and asked with some confusion, "You don't seem to be surprised." ”

"No, I'm surprised, but I think it's true, so you might as well move on to what's next!"

It's just the beginning, Qiu He is already full of interest in this blank history, and he is eager to know the next story.

Robin didn't ask any more questions, and continued to translate the ancient text with the mural.

The next mural is a spaceship with a unique shape...... That's right, it's a spaceship, Qiu He is very sure, this is a spaceship.

"In order to compete for the Sacred Tree, they unrestrainedly used the power bestowed by the Divine Tree to wage war, and eventually their planet was destroyed by themselves, and the race was also on the verge of extinction. The survivors could only take the sealed sacred tree and take the ark away. ”

Robin pointed to the spaceship on the mural and gave a professional explanation.

It seems that in this group of aliens, the spaceship is called the Ark.

"Then they came to our planet and stayed on the moon."

Qiu He pointed to the small circles of the two spheres in the third mural, which obviously referred to the planet beneath their feet and the moon as a satellite, respectively.

This group of aliens, who took root on the moon and became the early moon people, were the ancestors of the Sky Island people.

The ancient ruins on the moon, as well as the technology that surpassed this era, have a very clear explanation.

"Yes, they reached the moon and took root on the moon to multiply."

Robin then pointed to the fourth mural, a large map of the world,...... This is quite different from the current world map, at least this world map does not look so fragmented, and almost the entire planet is covered by oceans.

"They also discovered this planet located under the moon, they called it the 'blue ocean', although the environment of the blue ocean is also suitable for their survival, but because of the existence of indigenous people on the blue sea, and the land area is too scarce, these aliens did not rush to the blue ocean."

"Of course, they didn't leave the blue ocean alone, after all, the moon is too small for long-term development, and they began to transform the blue ocean. And out of nostalgia for their hometown, when they transform the blue ocean, they also move it closer to their hometown. ”

What follows is also a huge map of the world, but it is very different from the previous one, and it is very similar to the current sea charts, but there are some minor differences.

"Among the survivors, there are no scientific researchers who are proficient in technology, but they have an ark, and they use the power of the ark to control the movement of the continental plates located under the sea, and raise the land under the sea to create a land that surrounds the entire planet, which is now the red earth continent."

"With the increase of land, the number of indigenous people on the blue sea, that is, human beings, began to increase rapidly, and soon covered the whole world."

"Next, the moonmen were divided."
