Logically speaking, siege warfare is a very difficult and time-consuming affair.

But for Kryolev, he knew that he had only four days!

That's right, in four days, the Iron Giant will arrive at the Bonn Fortress, and at that time, with the powerful firepower displayed by the Iron Giant, it is impossible for him to break through the Bonn Fortress, so this four-sky window period is the only chance!

Cleorev didn't have a good way to deal with this, fortunately, although the Bonn fortress had the location of the Tiger Pass, it did not have the strength of the Tiger Pass. It was just an ordinary transit military fortress in Hermann, so the original defense facilities were not sufficient, and the walls were not too high, let alone heavy.

To put it simply, the Bonn fortress is more of a fortified version of a copycat, but it still lacks compared to the border fortress. Originally, in the eyes of Kriolev, it was the biggest weakness, but now, it has become his only advantage.

If only the Bonn fortress had been more formal......... Then he will only despair.

But now, there's still a chance.

"Inform everyone to prepare, and from now on I ask all the units of the First Army to launch a continuous attack on the Bonn fortress, and be sure not to give them time to rest. At the same time, I want you to divide three thousand men over the Cliff Mountains, interspersed from behind, and attack their supply forces! At the same time, send people to the rear fortress and put their ........."

At this, Kryolev lowered his voice and whispered a few words to Karl, who was stunned for a moment, and then nodded.

"I see, sir."

"Alright, let's do it."

Time is tight, the task is urgent, but if Kriolev wants to say that there is no way to do it, it is not so.

After all, before coming here, Kriolev had conducted a very detailed study of the Bonn Fortress, and at that time he originally hoped to rebuild the Bonn Fortress to resist the Inquisition. But now the exchange of offense and defense does not mean that the information that Kriolev learned before is useless.

First of all, the Bonn Fortress itself is not large, and it can only accommodate 3,000 soldiers at most, and none of the scouts he sent to the front line during this time have received information that the Fourth Army has mobilized a large number of personnel to the Bonn Fortress, so it means that the other party is likely to suddenly attack the Bonn Fortress in the form of a small number of elites in some way that he can't imagine. Of course, considering that the Bonn fortress was killed before it even had time to warn, it shows that this group of attackers is highly powerful, but there must not be many of them!

Since this is the case, then use the tactics of the sea of people to bombard them with fatigue!

The walls of the Bonn fortress are not high, as long as you use rockets to storm it, you can directly point this fortress!

Soon, the First Army also began to act, and the first to be dispatched, naturally, thousands of archers, holding lit rockets, shot at the Bonn Fortress in front of them, and then saw a series of fires piercing the sky and shooting towards the Bonn Fortress!

I have to say that Kryolev's idea is really good, the walls of the Bonn fortress are no more than three meters high, and they can't stop a large-scale attack at all, if these rockets are fired into the fortress and cause a fire, no matter how strong the other party is, there is only one way to escape. He didn't think anyone could stop such an attack!

But............... Next, a scene that stunned Kryolev appeared.

He watched as those rockets shot into the sky, and then fell towards the Bonn Fortress under the influence of gravity, and then ——— just as these rockets fell, suddenly a colorful barrier like a huge arc-shaped glass appeared above the Bonn Fortress, directly blocking these rockets!

“…………………？？？”

Seeing this scene, Kriolev looked confused, and he turned his head in surprise and looked at the adjutant beside him.

"What's that?"

"I want to ......... Probably magic? ”

"Can magic do this?"

As Herman's general, Kriolev certainly understands magic, and magicians do have barrier magic, but the scope of barrier magic is very limited, and it must be used by powerful magicians, otherwise it is useless.

Enchantment magic that can envelop an entire fortress?

What a joke!

"I've heard that the Seth Kingdom has sent people to join the ranks of the Inquisition, maybe it's their ability?"

"This ......... Unlikely, right? If Seth had this ability, he wouldn't have been forced by the demon army to almost wipe out the race. ”

Kriolev shook his head, he naturally paid attention to the fall of Seth a year ago, after all, everyone is a country that is facing the demons head-on, and the invasion of Seth by the demons, of course, it is impossible for Kriolev not to care. But he was sure that Seth didn't have this kind of ability at that time, and if he had this ability, Seth wouldn't have been beaten so badly.

In fact, as Kriolev thought, Seth really didn't have the ability to do this.

But ——— Manalia has it!

Also as a magical power, Manalia is several notches higher. Indeed, as Kriolev knew, the average magician, even if he could use a barrier, was not very large, and it would cost a lot of mana. But that's just a mage that limits this world, and for the mages of Manalia, this kind of protective enchantment is a basic operation.

You must know that when the royal city of Manalia was attacked by the evil dragon Fafna, and the latter hit his head on the city wall and was blocked by the enchantment, you can see how high Manalia's attainments in magic are.

To put it mildly, the gap between Manalia and Seth is basically equal to the gap between a full professor and a junior high school student.

Like this magic barrier, Seth's magicians couldn't make it even if they wanted to break their heads, and Ann and Gruya took Hannah and a few graduates to do it casually, and they just made it.

Anyway, it's just for temporary use, and it's not meant to be permanent.

For them, this is the difficulty of a midterm exam.

But for the people of this world, it is unthinkable.

"I can't imagine that magic can do such a thing........."

Standing on the city wall in a daze, looking at the barrier shining with multicolored brilliance above his head, and the flaming arrows that were blocked out, Uruzer couldn't help but sigh. Although she doesn't know magic, as a person from Seth, Uruze still knows a lot about magic, at least in the kingdom of Seth, although magicians are strong, they also have their weaknesses.

For example, with the exception of a very few level 3 mages who can use powerful group attack magic, the rest of the mages use some spells that can only attack people, and they are all very common spells.

But the magicians of Manalia completely subverted Uruzze's impression of magicians, and in their hands, magic is truly ever-changing, giving people the feeling of an incredible miraculous existence.

And......... How so...............

Thinking of this, Uruze couldn't help but look at Manalia and his party who were standing not far away.

These magicians ......... Well, it's all quite personal.

"This, this, this enchantment......... Is it really okay? Do you want to strengthen one, one, one ......... at a time? ”

A girl with brown-red hair wearing a huge witch hat that could almost wrap half of her body into it grabbed the broom in her hand uneasily, stared at the battlefield in front of her, and muttered to herself.

"Don't worry, Anna."

Soon, another girl beside her, dressed like a magician and holding a top hat and cane, smiled and comforted.

"This was designed by the two princesses themselves, and there will definitely be no problem."

As he spoke, he saw the top hat in the girl's hand flipped, and suddenly a cluster of flowers flashed from it and was sent to the red-haired witch.

"Come on, don't be so nervous, don't worry, we won't lose!"

"Ah............... Hmmm..............."

Hearing the magician girl's comfort, the red-haired girl also nodded as if relieved.

"Don't worry!"

At this moment, another blonde girl dressed like a nobleman proudly raised the staff in her hand and pointed forward.

"There's my genius magician Elsa! These enemies are not Miss Ben's opponents at all! As long as they dare to call, Miss Ben will let them know how powerful Miss Ben is! ”

"Alright, alright."

Just as the graduates of Manalia were excited, they stood behind them with blonde hair and clapped their hands with a smile on their faces.

"This is just the beginning, don't take the enemy lightly, right? Don't forget that your battle was not very successful the other day, so don't make similar mistakes again? ”

"Uh......... Got it, Milan teacher ........."

At the same time, Kryolev also found out that the bow and arrow did not work against the other side, and this time was only .........

"Attack!"

Soon, with the order of the veteran, under the cover of bows and arrows, the soldiers of the 1st Legion raised their shields and rushed towards the fortress in front of them.

And the people on the city wall naturally saw this scene.

"Okay, then then, it depends on how long you can resist each other, who will come first?"

"Of course it's Miss Ben, the genius magician Elsa!"

"Why should you be the first, you should let me, the flower of the sky——— Elena. Come on Gurolia, let these people see my strength! Let them know that flowers don't just bloom in the heavens and the earth, but can also shine in other places! ”

It's no wonder that the girls are so excited, after all, this time for them to go out to participate in the war is to be written in the graduation assessment, who doesn't want to get a good one?

Watching everyone's quarrel, another girl next to her who held a hand similar to a steel meteor hammer sighed silently.

"It's good anyway, please don't destroy the fortress anymore, it's very troublesome to repair........."

Beside her, several square robots on wheels were running around, mending holes in the walls of the fortress.

"Hey..............."

Milan sighed helplessly at these troublesome students, and then she looked at the blonde girl standing quietly next to her, wearing a silver-gray robe and hood.

"So, let's give everyone a demonstration first."

"Okay, teacher."

Hearing Milan's words, the blonde girl nodded, and then she came to the edge of the wall, looking at the Herman soldiers who were already close to the wall not far below. Then the girl reached out and took out a box of strange-looking matches from the basket she was holding in her arm.

These matchboxes are rectangular, but on the matchboxes, they are inlaid with gemstones of different colors. The girl reached out, took out a match, stared at the battlefield in front of her, and took a deep breath.

"The phantom of perfection will also prevail over the real......... Phantoms are also alive. ”

As she spoke, the girl swiped the match lightly.

With the flash of fire, the next moment, I saw countless pitch-black figures suddenly appear in the Herman army advancing below!
