Thea uses the fourth-order natural magic of nature, and within a certain range, she can learn about her surroundings through plants, and she can also see through the eyes of animals or hear with her ears.

With Thea's current ability, this range is roughly ten kilometers, and further away it is required for animals and plants.

For example, the plant has to be planted by her, and the animal needs to be her spirit animal.

Little Bird's Whisper often acts as Thea's "microphone".

Thea didn't hide and run away during the days she was lurking in Cartagena, leaving behind some plant seeds wherever she passed.

Now the seed sprouts, and the plant breaks through the ground and becomes her eyes.

"Ken Lohag has been guarding the gate of the Holy Descent, and I have seen the swelling and the soul." Thea said.

As soon as she heard the name of the Silent Soul, Orfina's eyes lit up: "The Silent Soul is in front of the door, why didn't this person come out?" My Soul Exterminator One is ready!"

"Possessing soul sounds and soul eyes, the Silent Soul is best suited to be in the center to liaise with the conductor and monitor the situation in the city of Cartagena." Thea explained.

Philia asked, "Will you be caught using the language of nature?"

"No, I just use plants and animals, not possess the past, and there will be no soul fluctuations, and the soul will not be able to discover me."

"Hmm. What is the situation on the other three fronts?"

"The artillery on the dwarven side has saved some, and you provoked Malkaem just now, I believe he can break through the walls before the day after tomorrow."

"Widnina to the west is sleeping, and she told me not to disturb her during the day...... However, I think the advance speed of the undead army is not bad, and I guess it can catch up."

"The fighting is very fierce in the east of King Charles, and the situation is not very optimistic."

Filia straightened her clothes and armor and said, "The army of the Eastern Road has barely rested, and when it arrives at the position, it immediately attacks the city, and the warriors are all supported by one breath. And there is no siege machine that Nana has transformed, and the siege efficiency is definitely not as good as ours."

"Well, Gruul is there, and the morale of the orc warriors is much higher than ours, so it's really hard to fight."

"But I believe in the abilities of Emperor Charles and Marshal Edrash, and they will be able to break through the walls. Thea, is there still no news from the Sea Clan?"

Thea shook her head: "No, the extreme south abyss is still closed, and no one can enter or come out for so many days."

The two fell into a short silence, and when Orfina saw this, she pulled the two of them and said, "Don't think about it so much, Cartagena is going to fight anyway, let's go to my brother and see if he has lost the cutie I made!"

The three girls left the command room.

Cartagena's walls were much stronger than those on the periphery that had been built overnight, and a single shot of a heavy trebuchet could only leave a small pit in the wall.

If you want to use siege equipment to collapse a section of the city wall, you can only concentrate your fire and keep bombarding, but the accuracy of heavy catapults and trebuchets is limited, and concentrated bombardment cannot accurately hit the same point.

If you attack like this, it is tantamount to a lottery. Philia didn't like to do uncertain things, so she decided to have the trebuchets and trebuchets focus on bombarding the enemy's fortifications and the concentration of defenders, providing fire support for the besieging infantry.

With fire support, the warriors rushed from their positions to the section of the road under the walls of Cartagena, receiving significantly fewer attacks, and in many cases it was enough to focus on defending against the arrows of the orc archers.

In this section of the death zone, the casualties of the soldiers are reduced, and the morale can be kept high, and the battle will be more courageous.

However, under the walls of Cartagena, the grinding mode was still on, and casualties were being inflicted on both sides at every turn, and the corpses were piled up more and more inside and outside the city.

The large number of spikes on the walls of Cartagena did not cause much trouble to the emperor team as Filia expected, but under the trimming of high-level and king-level powerhouses, they became a focus point for climbing.

The soldiers climbed up along the spikes, which was equivalent to an additional way to siege the city, which accelerated the progress of the siege in disguise.

But the city of Cartagena

The wall is not so simple, its structure is different from the imperial wall, and the wall leaves many holes.

These holes are not reserved archery holes, but holes for long, slender and sharp spears to pierce and retract.

The design of the spear is extremely peculiar, the stabbing and retraction are neatly aligned, and according to a certain pattern, so that at a glance it is clear that it is not controlled by man.

Moreover, not all of the spears were stabbed and recovered together, according to Rogge's estimate, they should have been divided into four batches, and the interval between the stabbing and retraction was inconsistent.

This is designed so that the besieging side cannot find the law, so that it cannot be circumvented, and the damage rate is increased.

About 30% of the casualties of the Imperial soldiers were caused by spears, which is a very terrifying statistic that deserves to be dealt with with in a special way.

Rog Gang led the flying spirit beasts to eliminate an orc air force.

The scale of this orc air force is not large, with flying monsters as the main force, and there are not a few bipedal wyverns, which are obviously used to delay time.

But the value of the Air Force is high, and Rogge will have to take some time to eliminate them.

Rogge looked at the regular stabbing spear that was withdrawn and a little worried, and from the appearance, he couldn't tell what its principle was at all.

The young man was thinking about whether to let the eight dragons in the spirit beast army, plus Canxing and Hai Jin, cover the city wall with dragon breath, and see if they could be destroyed together with the spear mechanism while killing the enemy.

Orfina came to him.

"Brother, why are you useless, my little cutie? Use it quickly and let me see how it works, and there's still time to improve!"

"Just wiped out an air force, and it hasn't had time to use it yet. Nana, you've come just in time, what is the principle of the spear?"

"Let me be well."

Arcane Master Orfina is an expert at making complex arcane devices, and if she can't even see through the secrets of the spear, she will have to think about attacking.

Orfina stared at it with wide eyes for a moment, then crossed her waist and said, "It's kind of interesting."

"How?" Rogge asked.

"It's not like it's controlled by a magic array, it's supposed to be mechanically driven!" Orfina concluded.

"Mechanically driven......" Rogge's guess was the same, because orc magicians were extremely rare, and it was impossible to put up such a large magic array.

"Nana, is there a solution?"

Orfina said, "It can only destroy the driving core."

"Can you guess the location of the drive core?"

"Yes!" Orfina pointed to the largest tower in the wall, "It could be there!"

"A mechanism that can drive so many spears at the same time must be very large, and it certainly won't be in a wall. Besides, if the device were hidden in the wall, it wouldn't be so strong if it had a hollow structure."

"Of course, every castle tower has the potential to have a driving core. Not...... It could be the other way around." Orfina scratched her chin, "The drive core is underground!"

"Goblins are very familiar with the underground environment, so it's a good choice to hide the drive core underground, which is safe and doesn't take up too much space to defend the city!"

Orfina's analysis made perfect sense, and Rogge praised, "Nana, amazing!"

"Huhu, of course! But brother, whether the driving core is underground or in the castle tower, it's not easy to destroy."

"Yes."

While the two were talking, the lives taken by the spears increased by a few hundred, and this problem had to be solved as soon as possible.

Rogge thought for a while, and then said to Orfina, "Nana, tell Sister Filia what you just speculated, and let her command the army to attack the various towers first."

"Also, the length of this spear is about one meter, and it should be able to be broken, but the pattern of the spear is difficult to determine, so I don't know where to start. You come and find a pattern and let the warriors break as many spears as possible."

"Attention, warriors, I'm going to lose the cutie you made."

"Okay!" Orfina leaves.

If the driving core of the spear device is in the tower, it is definitely the best choice to break through the tower earlier

However, if the core is underground, the Empire has no choice but to reduce the number of spears to reduce their power.

Rogge arranged it this way, just to make preparations with both hands and keep the casualties to a minimum.

A few familiar figures appeared over the city of Cartagena, but Rogge was unpressed.

The Martial Saint-level archer Rick is exerting his extremely strong long-range containment power, so that Shiva, Jebacs, and Zhan Po dare not move.

Matilda called for a battle outside the city, and they didn't respond, after all, on the southeast front, the imperial side was the more high-end side.

Filia will definitely adjust her tactics when she learns the news of the spear, and at this time, Rogge can do something.

When the offensive of the emperor *** team slowed down, and the soldiers adjusted their formation and did not storm the city wall again, Rogge led the team to set off.

Without the opponent's air force to contain it, and the bed crossbow on the city wall was also suppressed by our siege equipment, then the tactic was very simple, and the dragon's breath opened the way.

The two Star Glory Dragons, the three Sun Flame Dragons, and the three Golden Huang Dragons, led by Canxing and Hai Jin, went up to the city wall and lined up.

Ten dragons hung in the air, and the oppressive force was not ordinarily strong, and even the warriors on the imperial side held their breath.

Seeing this, Jebacs was about to rush to fight when he was forced back by an arrow that was so fast that it was almost invisible.

Rick is in control, and no one can act rashly.

Ten dragons opened their mouths at the same time, and they spewed out dragon breath in tacit understanding!

The brilliant galactic breath, the golden golden breath, the blazing flame breath, and the deep torrent breath rushed down and blasted towards the castle tower!

"Boom!"

After a few loud bangs, both human soldiers and orc warriors were shocked by the power of the dragon's breath.

The difference is that the human soldiers are quite excited, and the orc warriors are terrified.

Under the washing of the dragon's breath, the castle tower seemed to be bombarded by a heavy stone thrower several times in succession, among which the dragon's breath, which was dominated by the energy impact of the galaxy's breath, was the most destructive.

The tower under the bombardment of the three galactic breaths soon appeared to be seriously damaged, and at this time, Canxing still had the strength to spare, and the other two dragons had stopped spitting.

Canxing puffed out his last breath and spewed out the last of his dragon breath.

"Boom!"

A tower collapsed in half, revealing its inner structure.
