Tomorrow is 515, the anniversary of the starting point, and the day with the most benefits. In addition to the gift bag and school bag, this time's "515 Red Envelope Flip" must be seen, how can there be a reason not to grab the red envelope, set the alarm clock high~

Gently taking the ancient parchment scroll handed over by Nilou, Wang Xu carefully spread it out, for fear that he would tear it apart with too much force, because the parchment was already covered with many strange little holes.

There were small holes with black, charred black edges that seemed to have been burned, some small holes with strange edges, as if they had been gnawed by rats, some small holes, with regular shapes, apparently poked out by dagger-like weapons, and some small holes......

After carefully observing the design diagram on this parchment scroll, Wang Xu tilted his head in confusion, because the thing depicted on the picture is a bit like a two-stroke diesel engine, and this thing is not a device designed by the dwarf at all, because, on this thing, there are also many energy transmission lines and power arrays.

"This should be the goblin clan's mechanical design drawing, how did you get into the dwarven clan's equipment design library? Wang Xu turned his head to look at Nilou, frowning slightly in confusion, "Don't tell me, dwarves also know machinery?"

"Although I only know about alchemy, and almost completely understand mechanics, I have seen the things drawn on this picture, so I know what it is?" Nilou said in a firm tone as she stared at the design in Wang Xu's hand.

After listening to the conversation between Wang Xu and Nilou, the two sisters Zhana and the succubus also came around, and Zhana, who was obsessed with studying the formation, raised her eyes to look at Wang Xu after taking a look at the formation drawn on the design drawing, and whispered: "Power Array?"

"Hmm," Zana replied. After nodding again, Wang Xu turned his head to look at Nilou on the other side of him, and asked in a low voice, "What is on this, it won't be another useless equipment like an airship, right?"

"You guessed it right, but I don't know if it's still useful in this day and age. Nilou looked up at Wang Xu. He replied, "This is part of the blueprint for the castle in the sky." ”

After listening to Nilou's words, Zana's eyes widened in shock, her cheeks puffed out, and she quickly snatched the design from Wang Xu's hand and looked at it carefully.

And the two succubus sisters were also surprised, although they didn't know a trace of formation knowledge, but they had heard about the legend of Sky City. I'm fascinated by the city where you can fly.

"Oh," Wang Xu replied indifferently, his expression seemed very calm, he didn't seem to have any interest in Sky City at all, "I've heard of Sky City for a long time, I didn't expect to see its design here, it seems." Not bad. ”

"It's okay, it's a great city built by the goblins and dwarves working together. In the years I lived, the Sky City was a miracle to dominate the sky!" Nilou shouted to Wang Xu, speaking quickly and urgently, obviously not satisfied with Wang Xu's silent attitude towards Sky City.

"It's not that I look down on Castle in the Sky. I just think it's outdated, do you know how Sky City fell?" asked Nilou in a low voice.

"What, the city in the sky has fallen, it can't be, there are tens of thousands of dwarves and goblins living on it. How could it have fallen?" Nilou asked Wang Xu in a loud voice, and when she asked, her eyes glared at Wang Xu, obviously, she did not believe that the Sky City had fallen.

"It's still a thousand years ago, it's still the goblin clan, or the more powerful anti-aircraft weapons they invented, which directly knocked down the city in the sky, I heard that tens of thousands of people died in the fall, even the king of the dwarf clan fell to death, don't believe it, you ask the dwarf named Alva." Wang Xu raised his eyebrows and replied indifferently.

"Alva!" Nilou still didn't believe the fact that the city in the sky had fallen, so she shouted to the dwarven princess Alva and beckoned to her, "Come here!"

The dwarven princess Alva jumped up and running towards Nilou, and since the equipment she was wearing was not her own, the "jingle bells...... and all around her kept waking up old Warren who had just fallen asleep.

Old Warren opened his wrinkled eyes in pain, and when he saw that the sound was coming from Alva, he closed his eyes again, but the expression on his face was rather agitated.

When Alva ran to her side, Nilou crouched down, touched the long pink hair on Alva's head, and asked Alva with a smile, "Princess, is your dwarven sky city still there?"

"It's long gone, it was beaten down, it was beaten down by the trolls, I heard my father say that the city in the sky was beaten down a thousand years ago, and a lot of people died!" "Alva scratched her head and looked at Nilou with a clear look in her eyes, no one would believe that Alva would lie.

"Oh, that's right, princess," Nilou took out the rosewood princess chair that Wang Xu had given her from her spatial ring, put it beside her, and then carried Alva to the chair, and then whispered to her, "Sister has something to ask you, you sit down for a while, and I'll talk to your brother before I ask you, okay?"

"Good. Alva replied with a word, looking pretty good.

Looking at Nilou who stood up silently and stared at her, Wang Xu whispered to her after laughing dryly: "That's right, what sky city is just garbage!"

"Hmph," looked at Wang Xu with some grievances, and Nilou asked Wang Xu softly, "What weapon took down the Sky City?"

"Well, it's just a kind of artillery, it's not too powerful, it's just that the attack distance is a little far," after a moment of silence, Wang Xu continued: "You have already seen the explosive power of my Extreme Explosion Talisman, that kind of artillery, the power of each shell, is equivalent to one of my Extreme Explosion Talismans, that's all." ”

"How is that possible, how can such a small force take down the city in the sky?" Nilou asked, shaking her head.

"Quantity, one artillery is not powerful enough, just ambush a thousand, anyway, Sky City flies so slowly, even if I am alone, I can easily knock it down, as long as half an hour, I can paste the Extreme Explosion Charm on the power system of Sky City, then, it will inevitably be blown down!" Wang Xu replied to Nilou very casually, from Wang Xu's tone, Nilou heard that Wang Xu didn't look down on Sky City at all.

"Uh-huh......" Nilou was a little annoyed, her cheeks puffed out in anger, and she didn't know what to ask.

Suddenly, a knight who was there packing boxes, holding a great sword in his hand, shouted, "Come and see, ......what is this?"
