Chapter 711 The Secret in the Long River of History (Please subscribe, collect, and vote)
According to the analysis, Ryan and others believe that the ancient Laputans must have discovered the method of making flying stone crystals by accident, and then created a prosperous civilization based on the flying stone crystals.

However, due to the mismatch in technology levels, many problems arose after the floating city was built. Finally, the Laputans had to abandon the floating city and choose to return to live on the ground.

One of the most important is the problem of magic radiation. Just as Ryan analyzed before, the ancient Laputans had a very low utilization rate of the floating stone crystal energy, so a large amount of magic energy was released into the surrounding environment in vain.

This high-intensity magical energy is quite harmful to the Laputans who cannot master magic. For those who live in the floating city, they will find that if they stay in the sky city for too long, some malignant diseases will appear in their bodies. Especially for the next generation born in the floating city, because they are exposed to more radiation, the malignant diseases in their bodies will become more and more serious.

Finally, the Laputans, unable to solve these problems, had no choice but to abandon their floating city, the crystallization of their wisdom, and put it back on the ground. At the same time, they consciously blocked all technologies related to the sky city and flying stone crystals to prevent future generations from repeating the same mistakes.

However, just like the vibrant environment around Chernobyl, this radiation, although harmful to humans, does not harm plants and may even promote their evolution. The small ecological cycle on the upper level of the Sky City, which is like a primitive jungle, and the huge tree are a good example of this.

In addition, after the tree wrapped the flying stone crystal with its roots, part of the energy was filtered by the tree and reached the upper layer of Laputa, the city in the sky, nourishing the growth of all things in the upper layer. This is the most important reason why the upper layer's small and imperfect ecosystem can last for a long 700 years.

After Ryan told everyone his analysis, the entire control room fell silent. After several minutes, Xida finally woke up from the shock of receiving the news.

"Now I understand why Laputa perished." Sheeta said with emotion, "In the valley of my hometown Kenya, there is an ancient ballad that has been popular for 700 years. The lyrics go like this: roots must be planted in the soil, survive with the wind, spend the winter with bamboo, and sing praises to spring with birds. I think this should be the warning from our ancestors to future generations."

"You're right. This tree has pointed out a great direction for the development of Sky City." Ryan gently patted a tree root thicker than himself and said, "High-intensity magic energy will indeed harm people nearby, but the magic energy filtered by this tree will not only not harm the surrounding creatures, but will even promote the benign evolution of the surrounding creatures."

"Yes, that's true." Hermione nodded and added that she had discovered a little secret about the special energy cycle formed by this huge flying stone crystal and the big tree through her own method. "I think if you adopt the plant filtration plan from the beginning, 700 years will be enough for you to evolve generation by generation and finally master the power of magic."

When saying this, Hermione thought of the differences between wizards and Muggles in her hometown world. She now had enough evidence to prove that the ancestors of wizards and many magical creatures happened to live in a magical environment, and then evolved the ability to use magic and passed it down through genes from generation to generation.

Hermione even suspected that the ancestors of goblins, giants, or veela were actually humans, but they were irradiated with different magic from their wizard ancestors and changed their appearance. This would explain why, although they looked very different from humans, they had no reproductive isolation from humans.

Of course, it would be better to do these important research topics in their spare time. Now they need to find a way to hide this sky city.

"At least Laputa's own power cannot hide this city." Ryan and Hermione were busy for five or six hours, and it was not until the evening that they said helplessly to the two little guys who were leaning against each other and almost asleep.

"Didn't we see a huge storm surrounding this sky city before we came?" Baru asked in confusion. "Can't we just summon that storm again?" "If only it were that simple." Ryan said helplessly. "You have to know that the energy and difficulty required to stir up a storm in a calm sky is completely different from maintaining a storm. Now that many systems of the sky city have been damaged, once the storm is stirred up again, we basically cannot control the size and direction of the storm. What if the storm turns to the land——"

"You're right." Xida nodded. "Even if all the mechanisms along the way we came in are working properly, think about how such thick tree roots can reach this supposedly sealed space. This sky city must have changed a lot compared to 700 years ago. I believe that many things in places we can't see may not work properly as before."

"We just found that the weapon system of the entire sky city can function normally. As the core floating city of ancient civilization, the overall condition of Laputa's purely military systems is much better than other systems. For example, we can use this city to launch destructive lightning or control nearly 10,000 war robots to sweep everything around." Hermione said, spreading her hands. "But this is meaningless to us, because our spacecraft is enough for the flying battleship to destroy it. Now no matter how much force we have, it is meaningless to us."

"So what should we do now?" Baru squatted down and scratched his hair with both hands in frustration. "It's not enough time to hide this sky city with magic, and the power of the sky city itself is not enough to hide itself like in the past."

"Brother Ryan, Sister Hermione." Sheida suddenly stood up and looked at Ryan and the others and said, "Did you say before that you have your own country in other worlds?"

"Yes." Ryan nodded. "To be precise, we have our own countries in many worlds. But all countries are not very peaceful and are always facing wars of one kind or another--"

After that, he and Hermione briefly introduced several worlds, and finally concluded: "So there is another purpose for us to search for information everywhere, which is to hope to obtain enough technology to defeat those enemies and provide a better life for those who follow us because of their faith."

"That's right!" Sheeta nodded and suddenly said something surprising. "Then can you bring this sky city to your world?"

"What?" Baru turned to look at Hida in surprise. "Why do you do this?"

"It's very simple." Sheeta looked at everyone and said, "On the one hand, we have no way to hide Laputa for the time being. Once this flying city falls into the hands of an ambitious person, our world will be filled with blood and fire, and peace will be gone forever."

"On the other hand, even if we hide Laputa this time, with the development of flight technology, I believe that this floating city will be discovered one day. In this case, the only way to ensure safety is to hide the city in the sky in another world."

"Okay, I think we can hide this sky city in another world. But what will you do then?" Ryan asked worriedly. "After all, your identity has been exposed now. Unless you can hide in a place where no one is around, those ambitious people will keep searching for you."
