That was the target of this mission, Sylvie realized.

The scene in the center of the land was almost identical to the information provided by His Majesty Roland. The devils' city was built around the obelisk, but the obelisk was separated from the city by a chasm-like pit. Countless lesser devils clung to it, like worms parasitizing on the surface of a tree trunk, but upon closer inspection, they were constantly excavating the rock walls, further expanding the pit.

The red mist settled here, forming a red lake, and the towers near the pit wall would obviously fall into the lake in turn, becoming part of the giant pit.

It was rumored that the obelisk was not so huge at first. It broke out of the ground like a living thing and continued to grow, and the mine pit containing the red mist would continue to expand. Therefore, the age of a devil's city could be judged from these two points.

The city in front of her was undoubtedly astonishingly old.

Compared to the target, the silhouette of the biplane could only be described as insignificant. Not to mention the bombs it carried, even if it plunged into it entirely, it was hard to imagine that it could ignite the mist lake.

Suddenly, Sylvie let out a soft "Huh."

"What's wrong?" Wendy, who was attentive, asked immediately.

"Found a strange...devil."

A devil appearing on the top of the obelisk caught her attention. According to the devils' habit of worshiping the sky, those who could climb to the top of the tower must not be ordinary. Judging from its appearance, it was obviously not an ordinary devil. It was wearing a wide cloak that could cover three or four people, covered with dense ornaments. Zooming in, one could find everything from bone daggers to metal armor pieces. She even saw a few screws.

The enemy's head was also very special, shaped like a pillar, with many masks hanging on it, inexplicably making one's heart palpitate.

"Is its magic fluctuation very strong?"

"No...not strong." This was also the most confusing thing for Sylvie. Judging from its appearance, it was at least a high-level devil, but after appearing, it neither leaped up nor gathered magic to launch an ability. The only thing it did was focus its attention on the direction of the air knights' battle, with no intention of participating in the war at all.

Since it posed no threat to everyone, Sylvie didn't pay too much attention to it. Now, the two Fury Squads responsible for the bombing mission were about to approach the edge of the city, and she had to concentrate her mind to accurately judge the appropriate bombing position.

Two minutes later, she issued the bombing order via radio.

"Squad One, you may drop bombs."

"Gude, understood."

Even on a clear day, the clouds floating over the Impassable Mountains would not be too high. Coupled with the height of the fortress itself, the Fury, flying straight all the way, had not been detected by the enemy.

Five biplanes lined up in a column, dropping the one hundred and fifty kilogram aerial bombs hanging from their bellies at a steady speed.

At the moment the heavy bombs were unhooked, Gude felt the fuselage suddenly lift upwards, as if his body had become lighter.

Unfortunately, he could not witness the results of this operation with his own eyes.

Sylvie saw it very clearly.

Due to the center of gravity being in the front, the five aerial bombs quickly turned head down and fell towards the center of the city in a rapidly descending arc, relying on the inertia given to them by the aircraft. In the last five hundred meters, they were almost completely perpendicular to the ground.

And the devils also noticed these "uninvited guests" from the sky.

Another Terror Beast rose from the city and flew towards the clouds—but compared to the falling speed of the bombs, their movements were simply dwarfed.

Five black shadows successively darted into the city. The moment the bombs touched the ground, they turned into a ball of scorching fire, and the smoke and rubble they brought up were dozens of meters high, and their momentum far exceeded that of a 152mm howitzer! Even if she couldn't hear the sound, Sylvie could feel the earth-shaking shock from the surrounding violent blast wind and the splashing rubble.

At the same time, driven by the high-heat air currents, several distinct "holes" appeared in the red mist, like the air pockets formed in fluffy bread.

Looking down from high altitude, the slowly spreading gray-black smoke column was particularly conspicuous in the red mist—perhaps this city had rarely been attacked in the past few hundred years, but from the moment it broke into the Impassable Mountains to today, it had only been half a month, and the core area had been visited by humans twice.

However, Sylvie's heart sank to the bottom.

Affected by the wind, although the bombs had a rather large scattered landing point, they all fell into the city, which was much more accurate than the fortress guns. However, only two hit the mist lake, and neither of them made contact with the "lake surface" and exploded directly in the air.

At the moment when the fireball flashed, she captured a circle of rippling blue light waves—just like the barrier on the high-level devil!

"What happened?" Wendy noticed her strange expression.

"Around the obelisk...there is a magical barrier for protection," Sylvie murmured in a low voice, "The bombs failed to achieve any effect..."

"Hey, hey," Sylvie turned her head in disbelief, "Do you mean that the devil has expanded the barrier to the city level? How is that possible?"

She certainly knew that this was a bit absurd. The effect of the ability was often linked to the total amount of magic power. To make it effective in such a large area, even if all the witches were added together, it would not be possible. But the facts were in front of her, and she couldn't help but believe it.

That's right...that high-level devil located on the top of the tower!

At the same time as the thought emerged, Sylvie saw the other party again, but this glance almost made her hair stand on end, and an indescribable feeling surged into her heart—

She saw the latter stretching out seven or eight thin, withered arms at some point, taking off all the masks on its head, revealing the extremely distorted face below. More than a dozen overlapping heads looked into the air, among which there were devils and humans, and there were also those who did not know what kind of monsters they belonged to—the face of one of the women was particularly dazzling. They all showed different smiles, which could be described as extremely strange.

Sylvie couldn't bear it any longer, bent over and let out a burst of vomiting, and the ability was interrupted as well.

Wendy directly picked up the communicator when she saw this, "This is Seagull, Squad Two, immediately drop the bombs and turn back."

"Understood, did Squad One's bombing succeed?"

"No...there is a magic barrier around the obelisk, and the bombs failed to enter the pit."

"Barrier?" The other side was silent for a moment, "I see. But I want to try again."

"But there was an accident here, Sylvie may not be able to provide you with instructions for the time being, and the enemy's Terror Beasts are already approaching the clouds!"

"Don't worry, Squad One will cover us."

Wendy had no choice but to contact Tilly and report the general situation. The latter didn't care at all, "It doesn't matter, let Squad Two try, it's not time for us to collapse here yet."
