"Goo-goo, finally see the white clouds......"

"Daddy!"

Standing on the head of the tyrannosaurus dragon, the lightning chicken let out a sigh of emotion.

The trembling of Da Ya's whole body made Yang Kaibai mistakenly think that this was Da Ya's excitement after seeing the clouds.

The white clouds are misty and the sky is clear.

Breaking free from the volcanic ash above the Black Rock Mountain Range, this was also the first time Yang Kaibai had seen a blue sky in this world-

"It turns out that the sky can also be blue."

Yang Kaibai couldn't help but let out a sigh of emotion.

Wu Yuhan heard Yang Kaibai's sigh and nodded.

From the real elf world to the time and space of this past time and space, Yang Kaibai and Wu Yuhan have never seen the blue sky.

"Bo Li!"

"Saina!"

Through the thin clouds and mist, Shanaiduo and the fat ding she was holding in her arms saw a magnificent city that seemed to be surrounded by a dense atmosphere, and the huge land floating in the center of the world made the mouths of Shanaiduo and Fat Ding form an "O" shape due to shock.

"The castle in the sky at the center of the world!"

Yang Kaibai's eyes suddenly brightened, and the huge land floating in the air that he saw after clearing the clouds and mist was like the sect immortal land in the world of cultivating immortals, and the large number of flying elves flying around the Sky City even gave Yang Kaibai a feeling of traveling to other worlds-

The dungeon and the sky city, the underground and the sky, are like two worlds, but even if there is a world of difference, they are also like the robot Vali and Eva, their fates are connected.

Wu Yuhan had seen a model of the Sky City in the Suzuyama Mechanical University in the dungeon, but after being there, he was also shocked by the huge land city floating in the sky in front of him.

In the Sky City, there are not only orbital trains suspended in the air, but also countless large number of flying spirits shuttling between the orbits and the space of the tracks.

What shocked Wu Yuhan the most was the construction of the Sky City in front of him, just as he imagined as a researcher in the real elf world - this is a city where technology and elves are almost perfectly integrated.

In the face of Yang Kaibai and Wu Yuhan's shock and emotion, as the creator of Sky City, Steel Mewtwo did not show a trace of pride, on the contrary, its expression at the moment was extremely dignified.

"Steel Mewtwo, what's going on?"

As an emotional agent among the mechanical lifeform elves, Majiyana could feel the special fluctuations in Steel Mewtwo's body that no one else or other elves could detect.

Hearing Ma Ji Yana's words, Yang Kaibai and Wu Yuhan's shock when facing the main city of Sky City also restrained their minds a little.

Steel Mewtwo said in a deep voice: "Something is wrong, this disaster in the Black Rock Mountains...... The damage caused is much worse than I expected. ”

"We flew all the way and didn't see any other cities in the sky, which means that the environment in the sky is once again greatly polluted."

Yang Kaibai and Wu Yuhan felt a pang in their hearts.

Yang Kaibai gasped and said, "Yes, that's right, we came all the way...... The largest city in the sky at the center of the world is the only one we see. Since we can see the blue sky...... In terms of visibility here...... You should be able to see other castles in the sky along the way. ”

Wu Yuhan said in a solemn tone: "Steel, steel Mewtwo, volcanic ash in the sky...... Will it engulf the skies of Sky Castle? Isn't that the environment on the city in the sky......"

"Yes, yes!"

A picture of light shrouded in darkness came to the mind of Da Duck, and that picture ......

Duck Duck was taken aback instantly!

Don't ask how Duck Duck knows and feels, it's just ......

It feels familiar!

At this time, Mewtwo explained: "Every Sky City has a protective barrier to protect the city, and when there is a crisis similar to a volcanic eruption or acid rain in some areas, the protective barrier of the Sky City will be opened under the order of the city lord to protect the Sky City. ”

"It's just a volcanic eruption in the Black Rock Mountains this time...... Many Sky Castles are in an environment engulfed in volcanic ash, and it is okay for a short period of time, the protective barrier of Sky Castle has a maintenance period of 15 days, but if it exceeds 15 days, the harsh environment of the sky has not been improved...... Wait until the protective barrier loses power security, then ...... I'm afraid that the city in the sky will suffer a terrible incident of falling! ”

"Heavenly ...... Castle in the Sky Falling?! ”

Yang Kaibai and Wu Yuhan's eyes widened in shock at the same time.

The City in the Sky Falls......

What does this mean?

Yang Kaibai felt that his breathing had become extremely rapid.

This......

How many humans live in a city in the sky, how many elves live there, millions, tens of millions of memories, if you encounter the danger of the fall of the entire city in the sky......

Yang Kaibai couldn't imagine what kind of terrifying incident it would be!

"Boom, boom!"

Hearing Steel Mewtwo's words, even a ghostly elf like it who was as big as Kirbymon and didn't need to worry about lifespan, couldn't help but tremble a little.

Geng even felt like his ears were flat to airplane ears.

This......

This really makes the ghosts panic a little!

Yang Kaibai hurriedly asked, "Steel Mewtwo, this ...... How so? In the past, when the city in the sky encountered a crisis and opened the city's protective barrier...... There shouldn't be a chance that the castle in the sky will fall, right? ”

"Goo-goo-goo...... This, this is too scary! The lightning chicken was dumbfounded.

Steel Mewtwo was silent for a moment, his eyes seemed to be analyzing something, and then he said: "This world, after losing order and imbalance more than five hundred years ago, is like a candle, declining little by little, and finally running out of oil. ”

"The urban protective barrier of Sky City has indeed helped Sky City resist environmental crises from the outside world again and again, but every environmental crisis will cause irreversible damage to this world."

"The volcanic eruption of the Black Rock Mountains has made the world's already harsh air environment even worse."

"What's more, there are currently eleven Sky Cities affected by this crisis, and the energy consumption to maintain the protective barrier of the eleven Sky Cities is an immeasurable terrifying number! If the environment polluted by volcanic ash cannot be cleaned up to a certain threshold, the moment when the energy of the sky city is exhausted, it is the moment when the sky city falls into crisis! ”

Steel Mewtwo's words made Yang Kaibai and Wu Yuhan feel unprecedented pressure!

This......

Does it mean that the world has ushered in the countdown to destruction?! (End of chapter)
