The Admiral of Hogwarts

"Count down five numbers, then start the action." Without Indomitable's guidance through the Admiral's network, Wisconsin and New Jersey quickly figured out how to use the core magic circle.

Then, while manipulating the magic circle according to Indomitable's instructions, they coordinated with all the action personnel through the Admiral's network and prepared to attack.

"5, 4, 3, 2, 1—Start!" As Wisconsin's last word fell, she and New Jersey simultaneously activated the magic circle according to the method they had previously figured out.

In an instant, a surge of magic power flowed from their hands into the magic circle, and then the defensive magic on the door of the hall dozens of meters below disappeared.

"Boom—" At this moment, Missouri, who was already prepared, suddenly kicked off the ground and jumped out of the corner with her ship gear activated, while simultaneously firing shells at the golden gate.

Compared to the ship girls who cooperated seamlessly through the Admiral's network, the reaction of the Night Hag was obviously more than a beat slower. By the time the shells roared and smashed open the gate, flying into the hall, the Night Hag guarding the door had just turned her head.

At the instant the shells flew into the hall, the two ship girls in the control room immediately switched their manipulation of magic power and activated the final defensive magic, teleporting the entire hall to a sub-dimension.

After a ripple like water waves, the magnificent hall that had been visible through the broken gate disappeared, leaving only a dark hole.

"Ah—Kill them quickly." Although they couldn't figure out what had happened for a moment, the two Night Hags guarding the cave entrance immediately charged towards Missouri along with the four ogres.

Missouri and Iowa, at this time, each took out a short spear from their ship gear space and threw it fiercely at the two Night Hags flying over on broomsticks, then took out their M2s and strafed.

The short spears made of fairy silver and injected with the venom of the Eight-Eyed Giant Spider had a powerful killing effect on magical creatures, including wizards, so these two Night Hags were undoubtedly sent flying more than ten meters away and nailed to the ground.

Then, bullets flew from the machine gun's muzzle and landed on the four charging ogres. The kinetic energy of these large-caliber bullets was so great that it even made them jump off the ground.

"Combat over, prepare to retreat and avoid the heat." After confirming that the last ogre in the corridor was dead, Missouri raised a fist to signal a ceasefire, and then entered her own sub-dimension according to the original plan.

Although the ship girls didn't have to worry about the shells causing large-scale geological disasters in the area because of the space transfer magic circle, it was still better to avoid the high temperature left after the explosion returned.

"It seems that weapons of the level of nuclear bombs can also cause a considerable degree of damage to magic." After waiting for five minutes in the sub-dimension, Missouri suddenly said.

Before leaving, she had placed many items for reconnaissance in the corridor, and found that in just five minutes, an extremely high temperature surged out of the previous cave.

According to what New Jersey and the others said before, although activating it once would drain all the magic power in the magic circle, the level of the final defensive magic as a trump card was not bad.

Of course, this was much worse than the genuine magic used by pure-blood families, which could last for an hour, but theoretically, it should be able to last for half an hour.

But according to the current situation, the magic that was theoretically able to last for half an hour had now completely failed after only five minutes.

"There is nothing wrong with the thing itself." Indomitable's voice came through the Admiral's network. "It's just that the energy impact brought about by the nuclear explosion has a stronger impact on magic than we initially imagined."

"I think that's quite reasonable." Hugo said through the Admiral's network. "Don't forget, we all know that dense magic can affect electronic instruments, so the reverse effect should also exist."

Hugo had thought about this aspect before. He believed that this kind of interference between energies should be mutual, that is to say, magic and the power mastered by ordinary people can interfere with each other.

However, relative to the characteristics of magic, there is very little energy in the ordinary human world that is powerful enough to change magic. Therefore, there is basically no interference of ordinary human world energy on magic.

But now, after a round of nuclear strikes, Hugo and the others observed for the first time the obvious influence of the power mastered by ordinary people in this world on magic.

Unfortunately, this observation result will not be of corresponding use for a while, after all, today it was only by chance that the use of mk23 shells did not affect the external environment, but on most battlefields they cannot do this.

This does not mean that this discovery is without any value. At least after confirming that the core principle of this world is energy rather than anything else, they will always find a way to develop equipment suitable for manufacturing based on this principle in the future.

"Alright, we should go out and take a look." After confirming that the situation outside had stabilized, Missouri and the others quickly left the sub-dimension and came to the cave they had just been in, only to see a scene like purgatory:

The magnificent cave that had been seen after the gate was smashed had completely disappeared, and everything inside was in a special reddish-red molten state.

The energy generated after the explosion of a 15,000-ton nuclear weapon was released all at once in a small space, resulting in extremely terrifying effects.

Although so many Night Hags gathered together were a very threatening target even to wizards, and also had a lot of defense, they almost all perished in this attack.

The reason for saying almost is because just before the ship girls came out, a black shadow rushed out of the gate that looked like purgatory, and then quickly flew along the passage towards the ground.

Obviously, the existence known as the Mother of Night Hags was much stronger than the other Night Hags, and could even use some means to leave her body and act in the state of a soul.

"You guys go and scout the cave just now. Leave the things here to us." After listening to the ship girls' report, Hugo immediately issued an order, and then activated the magic circle that had just been set up.

The power from those ancient runes was immediately activated, and a force was ready to be released throughout the cave entrance. And not long after this force was activated, a black shadow rushed up from the cave below.

This black shadow looked a bit like the gas-form Voldemort from the first grade, but her luck was obviously not as good as Voldemort's in the first grade.

Just as this cloud of black shadow was about to rush out of the cave entrance, a large net composed of blue and white electric currents directly enveloped it, and then completely wrapped the cloud of black mist.

The black mist seemed to want to struggle, but the large net composed of surrounding electric currents quickly emitted a large amount of electric current, illuminating the entire black gas, and causing the mist to emit a sharp sound like fingernails scraping a blackboard.
