Although the murals on the wall are intuitive, they may not be fully understood. Because Ian found some symbols with unknown meaning in these patterns, he could only look at them with a guess.

From the pattern, we can see some cloud like pictures. After abandoning their hometown "bilka", the lunar people came to the blue planet and stayed on these clouds. Below the cloud pattern, there are some water wave like patterns, which may refer to the ocean below. Because Ian saw that there are some sea king like animal patterns on the water wave pattern.

That is to say, the first choice of the lunar people after they came to this planet was to live on the empty island. Ian saw from the murals that they built various buildings on the empty island of the Balong terminal and propagated civilization.

However, the size of the empty island was still small, so the lunar people began to split up, and they took flying boats to other empty islands.

There is no doubt that the empty islanders are the descendants of the lunar people. However, Ian can see that the original lunar people are divided into three races. They all have wings behind them, but one of them has smaller wings and two antennae on his head, which reminds Ian of the empty Islanders in his memory.

The other race, which seems to have bigger wings, should be the empty islanders of the strange monk urki race.

As for the last race, which also has smaller wings, but wears different animal headwear, which reminds Ian of the golden city of shandora. This race, I'm afraid, is the shandora people, because Ian can see from the murals that they seem to be leaving, not to other empty islands, but to the blue ocean below!

Yes, this branch of the empty Island did not go to other empty islands, but went to the ground. Ian could see that they came down with balloons in their hands!

That group of xiangdora people, is also the descendant of the moon people unexpectedly!? Ian was surprised by this, but why didn't they know the empty islanders on Angel Island who had the same wings as them after their island was washed up to the sky by the current?

Ian pondered it for a while. It is estimated that it may be caused by too long time. He did not know when the diversion time on the mural was. Maybe it could have been more than a thousand years ago. If it was true, then those shandoras who fell to the ground and propagated civilization might have suffered a blank history of 100 years. That would be a disaster, As a result, their cultural heritage has been broken, so they don't know about their ancestors.

It's no wonder that Ian had wondered before why those people in xiangdora, the Golden City, clearly live on the ground and even have wings behind them. It turns out that the real reason is here!

Ian then looked down at the murals and found that after the diversion, the murals behind only recorded the empty island. From the murals, we can see that the empty islanders on the island were suddenly disturbed after living for a period of time.

It was the blue ocean people who intruded into the Blue Ocean from below. What's interesting is that the blue ocean people recorded in the mural were actually a pirate ship! Because Ian saw the design of the skull flag from the ship.

Although they were pirates, these empty islanders didn't care. Instead, they were very friendly to them, entertained them, and then sent them back to the blue sea.

From the murals, we can see that the technology level of the empty island people is very high. On the picture, Ian saw the round hollow ball instruments they saw above. These instruments are arranged on the empty Island, and they can use electricity to drive the windmill to drive the empty Island forward at will. In this way, they sail over the ocean of the world, Look around for islands on the sea, and have friendly communication with blue ocean people.

However, when Ian was enjoying it, the mural stopped suddenly!

what the fuck!? What about the back!?

Ian looked around, hoping to see something about the back in the hall. Unfortunately, there was no back. The hall clearly reserved enough space to depict the murals, but the back parts were smooth and blank!

Not to mention Ian, even bby-5 was stunned, and she was looking at it with a guess.

"Why is there no one painting murals behind?" Bhaby-5 asked Ian.

"There may have been some major change." Yi An can only guess: "generally speaking, this kind of sudden interruption of historical records can only be a serious disaster, so people have no mind to continue to portray."

"Is that why the people on this empty Island suddenly disappeared?" "There are signs of fighting on the island, indicating that they may have encountered a powerful enemy," said bhaby-5

Ian nodded and agreed with her. He thought it might be the same, otherwise he could not explain the sudden interruption.

In other words, after coming to this planet, the lunar man has gone through three stages: one is the stage when all the races live on this island, the other is the stage when they are separated from each other. After that, it is the stage of great changes. At present, it is very likely to be a serious war. There are not only traces of fighting, but also traces of looting on the island, This shows that they may have failed in the end, so they can only escape from the empty island.

Ian thought of the balloons at the bottom of the clouds. Maybe the original empty islanders left with those balloons. It's hard to guess who their enemy is, but it's obvious that their enemy is not interested in the empty island people's city. After they occupied here, they took everything they could take away, leaving only an empty city in ruins. After a long time, all the energy of the empty island was lost, Finally, it has evolved into an empty island that can only float with the high-altitude airflow... So, when did this disaster happen? If the empty islanders fled, did they not come back after the enemy left? The history is too long, so long that many things can't be verified, so that there are too many mysteries left. Ian turned his eyes to the dwarf mechanical soldiers standing in rows. It is obvious that these mechanical soldiers are unable to move any more because they have lost energy. However, because Ian can control electric energy himself, he thought that if these mechanical soldiers can inject new energy into action, maybe he can learn something from them, I just don't know if they can speak... Ian looked around in the hall, and finally found the same hollow sphere instrument in the distance, and also saw some transparent pipes connected from the instrument, which crossed the position above all the dwarf soldiers. I don't know if it's OK, but Ian still wants to try. So, he mobilizes his mind power again and releases the lightning gun at the hollow ball. When the plasma ball appeared again in the hollow sphere, the instrument finally started, and a large amount of blue current began to spread through the transparent pipes. Zizi's voice sounded. Above the positions of the dwarfs, there was a lightning rod like thing, which received the current from the pipe. With the start of the instrument, the current instantly injected into the soldiers' bodies. Yi'an and bby-5 are looking forward to the process of charging these soldiers. Yi'an even thinks that he can charge these soldiers and make them active again. I don't know if he can make use of them? There are at least 500 such mechanical soldiers in this hall. If their combat effectiveness is OK, then... However, before Yi'an's dream is finished, the small dwarf soldiers who crunch and act together turn their heads and look at Yi'an and bby-5. Bhaby-5 hid behind Ian, took him by the arm and whispered, "Captain, do I have a delusion? Why do I see these dwarfs with red eyes? "“ You're right. It's really red! " Yi An's heart is full of warning signs, and his intuition is not good. Sure enough, the next second, these dwarfs soldiers even raised their spears and aimed them at Yi'an“ intruder! Destroy blue ocean people! Guard the ruins An electronic sound came, and these dwarf mechanical soldiers attacked Yi'an“ what the fuck! There's a problem! " Yian called out and said quickly, "baby-5, don't keep your hands!"
