While everyone was shocked by Vicente's ability to make them all float in the air and show how strong he could be against them, Vicente used his powers to change the electromagnetic properties of the part of his city that had already been built.
As it was, the city was just an ordinary place made of a lot of metal. But as Vicente brought this amount of metal under his control, part of his powers began to appear in the city's surroundings.
He controlled it masterfully and felt no difficulty in controlling such a large amount of metal. Since he was close to the peak of the 4th stage, Vicente could control a ridiculous amount of metal simultaneously.
Because of this, he was able to levitate all the men and women representing the wealthy families in the province while using only a fraction of his power on them.
'Impressive!' The Duke of the Province thought to himself, imagining that if Vicente wanted to, he could crush all those people with a single thought.
Meanwhile, other people were interested in this and other aspects of Vicente's power.
Some couldn't help but imagine how strong he would be when he added his fourth pentagram, while others noted the monster that lived in the province and that many people still underestimated, comparing him to ordinary Sovereigns.
'He must be as strong as a Paragon by now.' Thought one of Millfall's nobles, quickly realizing that Vicente was Cesar and that this young man could certainly fight above his level.
Vicente was probably already as strong as a Low-level Paragon!
As people watched Vicente's powers and the way he made special phenomena appear around the built-up area of the Metal City, the place changed significantly.
A powerful electromagnetic force appeared on the outskirts of the place while stormy clouds rose above the city.
The wind intensified, and lightning appeared from the sky, striking the outskirts of the Metal City but not the inside of the city.
The mana around the city became denser while the temperature dropped, and a terrifying aura emanated from the metallic place.
It didn't take Vicente long to do what he wanted. In just 8 minutes, he had completed the whole process, giving the city its first defenses.
When he was done, he looked at his guests and said. "Come, attack my city. Try out the defenses that will protect the area's inhabitants from monsters."
"That's..." The people obviously hesitated.
But Vicente insisted. "If you don't test it yourself, you won't believe it. So just attack the city as you wish. Don't worry, nothing will happen."
The people there hesitated a bit after he repeated his request. But after a moment of silence, someone moved, activated their powers, and showed their pentagrams.
That person tried to launch a long-range attack on the main square of that small town, launching something capable of destroying 3rd-grade buildings.
However, just as their strike was flying toward the city, an opposing force arose with great intensity, causing the attack to quickly lose much of its speed and gradually stop in mid-air.
Meanwhile, the mana from that move strangely dispersed.
Vicente explained as the people around were surprised: "his attack is based on the element of lightning. Since I also have an affinity for lightning, the mana used in that attack fell under the control of the Metal City, causing it to lose its power.
But even if the attack were based on another element, it wouldn't hit the city because of the electromagnetic barrier around it.
Mana itself has electromagnetism. Don't ask me why. I'm not a scholar. But it's a fact that everything in our world has electromagnetic properties. So, if you keep attacking, you'll see something similar happen again and again."
With these words, other nobles felt brave enough to do what he had encouraged them to, and soon, several of them began to attack the Metal City.
They didn't just attack the place with some of their power. Some of them put all their mana into their strongest attacks to test what Vicente had built there.
But the result was the same. Their attacks would stop before they even threatened any of the city's buildings.
Even if their attacks contained elements that Vicente had no affinity for, the mana from their attacks would eventually dissipate. The mana of an attack did not remain unchanged throughout its path.
If we were to analyze the mana in a revolver bullet like the ones Vicente's family had, the mana in the bullet would continuously decrease with each passing moment. If it took too long for the bullet to hit its target, it would lose all its power and become an ordinary bullet.
The same thing happened with all the elemental attacks. The attacks would be potent in the first few moments of the attack, and then they would quickly lose their power as time passed.
When these attacks launched against the city were stopped in mid-air by the electromagnetic barrier defending the place, they gradually lost their mana until they disappeared.
Vicente then said. "If any of you tried to enter the city where you shouldn't, you would suffer something similar. But the city would throw you away instead of repelling you until your energy dissipates."
He sensed a 3rd-stage beast on the outskirts of the nearby forests and used his power to enter the creature's mind and make it attack the city.
The men and women floating on the city's outskirts saw this and soon watched as the creature jumped toward the city, only to be repelled as if it had crashed into an invisible elastic surface.
The creatures flew in the opposite direction at great speed in a few moments.
"What if a 4th stage creature appears here..." Vicente was about to say when the lightning bolts formed from the surrounding clouds and hit the places he had indicated.
"Those rays will appear and attack the enemies. The problem with this city's defense capacity is that there will always be stormy weather around here." He finished explaining how his city's defenses would work.
"Incredible!" Several people murmured at the same time, understanding why Vicente's city would be so different from any other city in the province or even the kingdom.
To create all these phenomena, one would need Vicente's skills and a large amount of metal. The more intelligent of those nobles and wealthy individuals there could see that every metal part of the Metal City stored mana and elements and served as a battery for the phenomena presented.
Without this large amount of metal, it would be difficult to maintain all these defenses.
Their cities couldn't function like this, so they couldn't help but imagine how valuable this place could be in the coming era of disaster.
