The City of the Sky, also known as the Ring City, means the last trump card to defend the royal capital.

The Sky City is the masterpiece of the world's most famous alchemy, which can levitate up to three thousand meters in the sky, and the speed is very slow, but there is a magic legion resident in the Sky City, which is the ultimate weapon of the Seven Kingdoms.

In the ancient alchemy era, the masterpiece of the military competition of the Seven Kingdoms, when these things were made, it can be said that the materials of the whole country were exhausted, and for thousands of years, the Seven Kingdoms have been able to live in peace with each other, and it is precisely because of its existence.

Not only is there a legion of mage troops stationed in the Sky City, but there are also fifteen hundred magic cannons, and the city itself is a super magic array, and the magic array of the Sky City itself is engraved with two super spells, one is the forbidden spell-level Thunder Miles, and the other is the Land Sinking Technique.

However, the price of using these two forbidden spells is too great, and the current Seven Kingdoms simply don't have that opportunity to use them.

The blueprints for the production of the empty city are not a big secret, at least in the eyes of contemporary magicians, the city is not something that ordinary people can get at all, and even if the drawings are given to him, he does not have the financial resources to complete the construction.

A few kings still wish that someone could pay for the construction of one, and when the time comes, in the name of the kingdom defense war, just levy it, anyway, you won't use it to rebel, even if you rebel, you have to have a legion of mage troops to be able to activate the core energy in it.

No, the representative of our great aristocracy, Prince Palathu, is going to visit the empty city today, and he is also carrying a "thief", planning to come to a good show of a thief shouting to catch a thief.

But what he never expected was that when he and the magician who accompanied him casually mentioned the blueprints of the empty city, they looked at him as if they were looking at God, and said to him with adoring eyes and tones: "Does His Royal Highness want to build an empty city himself?" ”

His eyes lit up frighteningly, and the prince said a little weakly: "I, I just want to see the drawings, and if I can, I would be willing to get one out and contribute to the defense of the kingdom." ”

"Really?" The accompanying court mage raised his voice an octave, his hands folded, like a devout believer, looking at him with blank eyes.

"Ahem, of course, I know you might be struggling, so I'm just going to take a look." His Royal Highness took two steps back without a trace, but he couldn't help but wonder in his heart: Something is wrong with this guy's expression, what the hell is going on?

Glancing at the accompanying "steal", I felt that this guy was a little weird.

"Hahaha, Your Royal Highness, you are such a good person! I'm going to bring you the drawings, you wait for me, don't leave! "The court magician almost floated towards the empty city with the steps of a young girl, and Gao Xin seemed to have won millions of gold coins.

His Royal Highness the Prince and Mr. "Steal" glanced at each other, and suddenly there was a bad blessing

Sure enough, while he was waiting, it didn't take long for a large number of magicians to arrive, and the fanatical expression on their faces almost made him feel like an ancestor.

Even His Majesty the King, who heard the news, was much more enthusiastic about him, took his big hand, and said intimately: "Ouch, my brother Wang, your support is a shot in the arm, at the juncture of national crisis, if you support the construction of a new empty city, we will be more confident in resisting the attack of the invaders, come on, Brother Wang, let's have a good chat, let's have a good chat, I didn't expect that I have so many brothers, you, you are the most sensible, hey......"

His Royal Highness was dragged to the side hall by the king with a confused look and talked about it, His Majesty the King looked eager, after all, he knew that if his royal brother really wanted to invest in the construction of a new empty city, he would definitely not have enough manpower, so His Majesty the King began to sell the court mages under his hands.

babbled on and on to His Royal Highness the Prince with a large amount of data that he didn't understand, but every data had the word gold in it.

His Royal Highness resisted the urge to beat him, and waited patiently for the long-tongued mage to come over with the blueprints.

Finally, after the nagging in his ear, the big-mouthed court mage brought what he wanted.

The drawings were loaded into an ordinary box, and if His Royal Highness was not dazzled, there were still some traces of wiping on the box, which was the dust generated by how long it had been placed.

He complained frantically in his heart, His Royal Highness the Prince is actually still a young man, but he is just afraid of death, and now the drawings of this Zhenguo artifact have appeared in his hands, as if he is dreaming.

"Brother Wang, open it and take a look, this is our heritage." The king looked at his young brother with a smile, hoping that this guy would not be startled by the contents, otherwise it would be a little difficult for him to ask for money at that time.

However, His Royal Highness didn't think too much about it, anyway, this thing is ultimately going to be given to don't spare, just see for yourself, isn't it just money? For the sake of his own life, he is willing to give more money, and when the time comes, he will have an explanation for the other party, right?

Thinking of this, his mood suddenly became much better, he took out the drawings, handed the box to Mr. "Steal" next to him, and gently unfolded the drawings on the table.

The honest emperor himself saw the true face of the drawings for the first time, as if a world had been opened, and both of them looked at it with some trepidation.

I saw that the design on this drawing was really very complicated, and the countless annotations alone made people dizzy and in a trance.

Not to mention the various strange materials in the annotations, the drawings reveal the empty city in detail, and the secrets inside.

His Royal Highness was finally attracted by the core of the empty city, and he pointed to the core energy part and said, "This thing, with our current technology, can it really be made?" ”

Looking at his brother with suspicion, His Royal Highness was a little disappointed, the kingdom is really in decline.

The Emperor shook his head awkwardly and said, "I don't know, but we can try to mimic the existing energy core of the Empty City." ”

"Imitation one?" His Royal Highness sighed helplessly, and pretended to regret and said: "The drawings are temporarily borrowed from me to play, Brother Wang, I know that the domestic situation has been turbulent recently, so I will give you five million gold coins, I am not rich anymore, Brother Wang...... Ay. ”

The king was stunned, he didn't expect his royal brother to really give money, although he didn't mention the reconstruction of the empty city, he also knew that it was just a joke, but his younger brother would directly give him money and support him, which made him a little moved.

The drawings were also left to him to take with him.

Putting the drawings into the box, His Royal Highness's own heart was beating, he never expected that today's action would go smoothly, and the bad things planned before were completely useless.
