Within two hundred meters of the outer walls of Cartagena, the ground cracked and collapsed rapidly, revealing an unfathomable ravine.

Filia immediately ordered a retreat after noticing the anomaly, but the ground fell quickly and rapidly, and more than half of the Imperial warriors still failed to escape and fell into the ravine.

At first, the crowd could still hear the roars of the warriors who had fallen into the ground, as if they were fighting some creature.

Then the roar grew quieter, the eerie rustle grew louder and louder, and finally, the underground fell silent, like the walls of Cartagena after being enveloped in poison gas for some time.

The warriors at the edge of the ravine could clearly see a pair of purple eyes lit up in the dark ravine, as if a group of hellish demons were staring at them.

Rogge also saw that these eyes were very special, and he immediately ruled out the eyes of goblins and orcs, and then looked closely, and also ruled out the common underground monsters.

What kind of creature is it? Could it be a monster from the Red Abyss?

The fall of the ground was undoubtedly a disaster for the emperor team who were attacking in groups, not only suffered heavy losses, but was also blocked by ravines and could not continue the attack.

The troops on the city walls had no support from follow-up troops, and could only resist the frantic attack of the orc army in the city under the cover of the air force.

Although the emperor's team guarded the stairs everywhere to occupy the high points, the difference in strength between the two sides was too great for them to hold the city wall.

Bright Star flew to Filia, who was observing from the edge of the ravine, and said to her, "It's the Abyssal Beast, I feel its breath."

Yaoxing and the Abyssal Beast had just fought, and it didn't take long for the Abyssal Beast to run away, and the injuries were not too serious, and they were fully capable of attacking again.

The Abyssal Beast should have also sensed that Yaoxing was nearby, and this time it didn't dare to show its head when it learned wisely, so it didn't give Yaoxing a chance to beat it.

The abyssal beast stays underground and doesn't come out, but the threat to the emperor *** team is even greater, this ravine is likely to be made by it, and no one knows if it can be made a few more times.

It is necessary to probe the underground situation in advance to avoid heavy casualties due to the recurrence of ground cracks.

Filia decisively adjusted her tactics: "Herald, notify the commander of the mage unit, send the earth mages to disperse among the armies, and report it immediately if there is any abnormality in the ground."

"Yes!" The herald took the order and departed.

"Bright Star, can you help us keep an eye on the Abyssal Beast?"

"No problem!" Yaoxing patted his chest, "As long as that big bug dares to show its head, I will be beaten up!"

"Thank you, only you can suppress the Abyssal Beast, and the key to the success or failure of this battle lies with you." Filia said something nice, and Bright Star was very useful, and let out a majestic dragon roar into the ground on the spot, killing the courage of the Abyssal Beast.

The abyssal beasts that can operate underground are really difficult and difficult to prevent, so the dazzling star can limit one or two.

"Nana ......"

Before Filia could finish speaking, Orfina took out a few flashbangs and threw them into the ravine, and there were a few muffled "bangs" and the ground lit up.

Taking advantage of the light, everyone looked at the probe and finally saw clearly what kind of creature those red-eyed owners were.

Their upper body is humanoid and the lower body is snake, like snake monsters that have not fully transformed.

They have a varying number of arms, ranging from two at the least to eight at the most. Monsters with two arms are in the majority, but these two arms are not located in the same position as humans, growing in the middle of the torso near the waist.

The weapons in the monsters' hands and the armor they wore looked strange, but the metallic sheen showed that they were well-equipped.

Obviously, this creature is not a magical beast, and no magical beast can be semi-transformed in a swarm. They also do not fit the characteristics of any of the intelligent races recorded in history, and can only come from other worlds.

"Wow, that's ugly!" Ofina patted her small chest and unleashed a blessing spell on herself to suppress the disgusting feeling.

The combination of the snake body and the human body is quite terrifying, and with the strange growth of the arms, the shape of the monster deserves the word "ugly".

"Thea, do you recognize you? It's a demon

Is it?" Filia asked.

"I haven't seen it." Thea stared at the monster underground, her eyes deep, "I'm not sure if it's a demon, but it must not be a native creature of the Heth world."

"Yoo!"

Yaoxing suddenly let out an angry dragon groan, and turned into a giant dragon flapping its wings, and spewed out a galaxy breath at the ravine!

The dragon breath of the soul heaven-level dragon burst incomparably, and even the imperial warriors on the edge of the ravine were shocked, and they felt the breath of death when they were too close to the dragon breath.

The galaxy's breath poured into the ravine, and the group of monsters suddenly screamed and scattered and fled into the depths of the earth, but the power of the breath was huge, and a large number of monsters were still annihilated by the dragon's breath.

Two eight-armed monster leaders suddenly rushed out of the monster group, and they looked like a male and a female, and joined forces to release a skill similar to a fifth-order large-scale position magic shadow curtain, blocking all the energy impacts spread by the dragon's breath.

Those who can resist the Shining Star Dragon Breath are definitely the strongest, even if they are resisting the residual power of the Dragon Breath, they are really resisting.

In this way, the more arms this monster has, the stronger it becomes.

Bright Star drove away the monsters in the ravine with a breath of dragon's breath, and there were no more pairs of red eyes peeping inside.

The width of the ravine, which is the width of the ground subsidence, is about two hundred meters, covering the entire front.

If you want to continue the attack, you have to find a way through the ravine.

The most powerful earth mage in the Emperor *** is a mage, and he alone cannot repair the ground in a short period of time.

Filia thought for a moment and decided, "The attack is suspended, and the surface is repaired first, and a way to cross the ravine."

"Miss, what about those warriors trapped on the city walls?" Myron, a knight loyal to Filia, asked.

"Rogge will have a way. Tell the equipment battalion to adjust the angle of fire and concentrate fire on the troops on the city wall to help them evacuate."

"Evacuate ......," Myron looked at the sky and realized.

You can't walk on the ground, but you can walk in the sky. The Imperial side firmly occupies the air superiority, and although there are not many flying spirit beast troops, it can still be done by helping the troops trapped on the city walls to retreat and flying a few more times.

Rogge and Philia glanced at each other, and the two understood each other's thoughts, and Rogge immediately led the air force reinforcements to retreat.

The follow-up archer units of the Orc Alliance also came to the front line, and the air force finally felt the pressure.

In terms of long-range forces alone, the Air Force has an absolute advantage.

There is such a saying in the emperor's ***: high fights low, and stupidity [silence].

The air force is much higher than the ground troops, whether it is bow and arrows or magic, the range and power from the sky to the ground are greater than the ground facing the sky.

But again, the problem is that there are too many enemies, and quantitative changes can cause qualitative changes.

A dense rain of arrows poured into the sky, hitting the dragon's scales like raindrops on the body, but Pegasus knights and the more fragile magical spirit beasts had to pull up the heights.

"Eleanor, drop the rest of the gas bombs!" Rog gives a loud order to Eleanor, the leader of the Hope Flame Pegasus Knights.

"Yes!" Eleanor gathered her team, flew to the right position, and threw a gas bomb.

This time it didn't need to be as precise as if it were dropped on a wall, so the height didn't have to be lowered too much, and the Pegasus knights could finish the throw in relative safety.

The poison gas bomb flew in an arc towards the orc army in the city, this time the orc warriors were not as flustered as before, several king-level powerhouses intercepted it, and the poison gas bomb exploded several times in mid-air.

However, as long as the poisonous gas is strong enough, it can also have the effect of blocking the line of sight when it explodes in the air, not to mention that the poisonous smoke will gradually sink, and it is not a big problem to be intercepted.

No sooner had the gas bomb exploded than the orc overseers whipped their whips and yelled at the troops to disperse.

The terrain in the city is relatively wide, and eighty percent of the orc troops within the poisonous smoke range can escape, and the lethality of this wave of throwing is far less than that of the city wall.

Rog had the Flame of Hope team throw the remaining gas bombs not to kill the enemy, but to cover it.

As soon as the poisonous gas spread, Rogge immediately led the air force into action, and the Pegasus knights with low load-bearing capacity and flying insects swooped down to kill, and the remaining spirit beasts grabbed the soldiers trapped on the city wall and retreated in an orderly manner.

The cover projection of the equipment battalion also arrived, and the flames and stones fell in the orc army, smashing countless orc warriors into pulp.

Thunder and lightning and flames poured down from the sky, dealing a fatal blow to the orc warriors who stormed the stairs, and the orc warriors fell in the magic of the spirit beasts, and the pressure on the imperial soldiers on the city walls was greatly reduced.

The spirit beast flew back and forth five times, and when the poisonous smoke just cleared, it rescued all the trapped soldiers.

The orcs reoccupied the city walls and planted the battle flag of the orc alliance on the tower.

The results of the Imperial side were not bad, although they failed to break through the city walls in one fell swoop, but destroyed the driving core of the spear defense device, and the difficulty of attacking the city was greatly reduced in the future.

What's more, this battle forced out the opponent's two hole cards, one is that the earth will fall, and the other is that there are monsters from another world underground.

Underground combat is something that the Emperor *** team is not good at, and it is necessary to let the earth magician monitor the underground situation at all times to avoid ground cracks.

With Filia's command ability, the impact of the ground crack can be minimized, and the estimated time of breaking the city remains unchanged, or tomorrow at the earliest, and the day after tomorrow at the latest.

The defenses of the Cartagena wall in the southeastern section were exhausted, and the southeastern route army had a short time to repair before the problem of fissures and ravines could be resolved.

The Eastern Army led by Charles and the Northern Dwarven Legion led by Malkaem entered the most intense stage of the battle.

Both armies advanced in front of the defense line of the third layer of fortresses, which could be supported by the city walls and was the most difficult layer of fortresses to breach.

The Eastern Route Army lacked improved siege equipment and air support, so it could only use its life to attack to the death.

Compared with the steady advance of the southeast road, the attack of the army on the east road was more violent and crazy, and it was completely a situation of disregard for losses.

Because the warriors rushed all the way to the position, lacking rest, they had to achieve the results with an invincible momentum, and at least advance to the city of Cartagena to have any hope of breaking the city in time.

The corpses of the Imperial warriors under the fortress were piled up in a thick layer, and the follow-up troops were completely stepping on the corpses of their comrades, similar to the situation when the orc army attacked the Hogaka Line.

The dwarven army was in a better situation, and the stimulated Malkaem did not directly let the army press, but sorted out the remaining artillery and continued to bombard the fortress.

However, the fortresses bombarded this time were screened, basically bombarded one by one, and the remaining fortresses could not form a coordinated defense, and they would be much easier to break.

When the third layer of the fortress was bombarded into a dog-tooth shape, Malkem finally ordered the whole army to attack.

The dwarves' heavy armor was completely unafraid of the orc's arrows, and the fire oil caused them a lot of trouble, but the dwarves' stubborn temper kept their morale high, and it was only a matter of time before they fought against the fire and conquered the fortress.

Compared to the difficult situation of the other three-way armies, the siege of the undead army on the western road seemed to be very calm.

Although Gnison promised Vidnina to let her into the city, the undead army did not stop.

Vidnina would love to kill some more orcs and recover their corpses, so she won't miss such a great opportunity.
