Chapter 334 - Monster Wave

*KYYAAKKKK* Then, a gigantic spider appeared in front of everyone's eyes. 

Looking at the gigantic spider, "Grade five Steel Broodmother!!" exclaimed Duke Jacob.

"That means there will be some other fourth-grade spider monsters." said Fosa.

Not long after that, many spiders in different colors followed the Steel Broodmother around them. These giant colored spiders are called elemental spiders. Although they are big compared to other spiders, they still look small compared to Steel Broodmother, who is a colossus monster.

None of these elemental spiders dare to be near Steel Broodmother since it eats any monster nearby it once in a while. Broodmother spider monsters are famous for their gluttony and large stomach. There is a rumor that it often eats half of its child after laying thousands of eggs. 

Seeing the colossus Broodmother, "Borkins, I will leave the Fortress to you." said Duke Jacob as he cast a flying spell to himself.

"Burned that bug to ash!!" replied Borkins.

Then, Jacob immediately flies towards the Steel Broodmother. A colossus monster like Steel Broodmother needs to be handled separately. Otherwise, they could break or damage the Fortress wall with its body. 

Moreover, as a fifth-grade monster, it also possesses some ability to use large-scale attacks such as Miasma Blast. With its large scale, its Miasma Blast could easily break the wall and half of the Fortress. Therefore, Jacob needed to fight the Steel Broodmother far from the Fortress.

Still, Jacob is not alone, like when he deals with the Corrupted Mother Treant. Seeing that the Duke is battling the Steel Broodmother, Anne and a few of the explosion squad combatants also immediately follow the Duke.

They had already planned this arrangement before. Anne and some fourth-grade combatants will help Duke Jacob fight the Fifth-grade monster in a separate area. 

Most of the fifth-grade monsters are surrounded by many other monsters. Therefore, fighting a fifth-grade monster alone is too dangerous.

Approaching the Steel Broodmother from the sky, Jacob immediately flared up his mana and scorched the nearby low-grade monster using his fire mana. A moment later, he cast a spell towards the gigantic Spider [4th Circle - Inferno].

*BOOMMM* Big fire explosion enveloped the entire Steel Broodmother, even killing all the nearby spiders or monsters. After the smoke cleared, the Steel Broodmother looks uninjured and only gets enraged but Jacob's attack.

Looking at this, Jacob knows it will be a hard battle. Like its name, Steel Broodmother's body is enveloped by a kind of hard exoskeleton similar to steel. However, this metallic thing is getting harder along with the grade of Steel Broodmother.

As a fifth grade monster, the Steel Broodmother exoskeleton is even harder than diamond. Steel Broodmother's specialty is not on its attack but its defense.

Seeing that his attack is ineffective, 'This will be a long battle. I hope the others can hold on for a while.' thought Jacob.

"Anne, buy me some time." said Jacob while moving around in the air, not letting the surrounding monster target him.

"Yes, sir!!" replied Anne while exterminating the nearby monster.

While Jacob and Anne handle the Steel Broodmother, many fourth-grade elemental spiders reach the Fortress wall and easily climb on it. 

Elemental spiders are monster spiders that could use an elemental. Some of the fast thunder elemental spiders even managed to climb the wall. Then, they start killing the soldiers and adventurers on the wall.

"Hold back!! Keep in the formation!!" shouted Borkins.

At the same time, Fosa and a few other fourth-grade combatants immediately fight off against the climbed elemental spider. Angus and the others also do not stay idle and help the others.

While the chaotic battle happens, more high-grade monsters from various species appear from the forest. Seeing this, Angus immediately triggers the hidden bomb rune on the field.

"Release!!" shouted Angus.

Suddenly, the many spots surrounding the field shine brightly, and a ball-sized bomb shoots out into the air. Less than a split second later, all these bombs flashed and exploded. *Flash* *BOM* *BOM* *BOM*

Along with the bomb, many small marbles scattered into the surrounding. Then, countless small explosions were triggered. *Bom* *Bom* *Bom* *Bom* *Bom* Soon, the explosion covered the whole area. Fortunately, the whole Black Fortress already deployed a strong barrier.

Still, the explosion managed to shake the whole Black Fortress and its surrounding. Even Jacob, that is quite far from the location, could feel its shockwave. Angus's rune bomb trap managed to kill all the monsters in the field completely. Even the survived one is on the brink of death.

This gives Fosa and the others some time and breather to eliminate the climbed elemental spiders. Still, the monster wave is far from over. After a while, more monsters from various kinds of species appeared from the forest.

Despite this, everyone is highly moral and not afraid of the incoming monster. They are even eager to kill this monster. Seeing Angus's bomb twice makes them feel that they could survive and win this battle.

On the contrary, the current approaching monster wave consists of third and fourth-grade monsters from various species.

"Artillery, shoot!! Keep firing as your life depends on it!!" shouted Borkins to remind everyone to keep firing.

However, these monsters are pretty fast and manage to reach the wall easily. Fortunately, there are no Barculos or wall-breaker monsters among these monsters. Otherwise, they need to confront the monsters directly.

Some of the monsters climbed the wall while some got killed under the wall. As more monster corpses piled under the wall, it created footing for the approaching monster. 

Explosions, shouting, howling, screaming, and many disturbing sounds were heard all over the place. Now, most of the soldiers and adventurers beside the artillery unit confront the climbing monster.

Some low-graded soldiers and adventurers already retreat to recover their mana. At the same time, the third-grade and high-grade combatants fought in a team while conserving their mana. Even Borkin also began to massacre the monster using his warhammer. 

Angus also didn't stay idle and kept spamming his spells nonstop. Suddenly, Angus smells a stinky smell from the forest.

"Urghh.. It's smelly?!!" said Anna, who also has a good nose like Angus.

Despite all the bloody smells in the field, this stinky smell still permeated the whole area. In the outskirts of Dark Forest, many giant bug monsters on four legs with red color and white polka dot color on their back appeared.

The insect monster is similar to Lady Bug on earth but many times bigger. Seeing this monster, Angus immediately feels horrified.

"Shit!! Kill them!! Hurry, Kill those red bugs!! Shoot them down!! Don't let it approach the wall!" shouted Angus.

In the meantime, seeing many prey in front of them, the red bug spread its wings and flew towards the fortress. Seeing that the red bug spread its wing, Angus immediately gathered and flared all his mana to the limit.

Just as the red stink bug almost reaches the fortress, Angus releases a large-scale Vulcan Shot to them. *Bam* *Bam* *Bam* *Bam* As soon as the Vulcan shot hit them, the red stink bug exploded and damaged the surrounding area.

The explosion is similar to a medium-size bomb. Unfortunately, the red stink bug is in the air and couldn't give too much damage to the surrounding monster. Still, this scene surprised everyone.

The red stinky bug is actually a rare monster called the Explosion Bug. The explosion bug releases some kind of stinky pheromone towards the surrounding area to deter the other monster from eating them. However, this pheromone is also highly combustible.

As someone who researches many things about explosion skills, Angus managed to read these rare monsters during his research. If it is not because of its relation to the explosion, Angus may not know these terrifying stinky bugs.

If they managed to reach the Fortress wall, countless people would easily die as soon as they exploded. Exhausted his mana, Angus immediately chucked a high-grade mana potion.

"Haa.. Haa.. I never thought I would still need mana potion despite my high regeneration." said Angus.

At this moment, everyone's face is distorted as they smell a very stinky smell from the forest. A house-size explosion bug slowly appeared on the forest outskirts. 

Seeing the gigantic size of the explosion bug, "Shoot it!! Magic Cannon shoots that bug!!" ordered Borkins.

Few Magic Cannons release their concentrated mana beam towards the slowly approaching Explosion Bug. *BAM* *BAM* *BAM* Contrary to everyone's expectation, the explosion bug is not exploded under the Magic cannon.

Instead, the explosion bug becomes angrier and releases massive pressure towards the surrounding area. Suddenly, the gigantic explosion bug shine brightly *Whooshh*

"T-This is… it's upgraded into a fifth grade!!" said Fosa.

Seeing that the explosion bug reached the fifth grade, Angus began to feel this was the worse situation. The explosion bug range will be more enormous and destructive along with its grade. 

The majority of the explosion bugs that Angus killed before are only third grade, and it is comparable with the medium size bomb. Angus didn't know about the fifth-grade exploded bug, but its explosion surely could cover the whole Black Fortress.

Seeing that the gigantic explosion bug turned into a fifth-grade monster, Angus immediately cast a spell towards the ground below the monster [2nd Circle - Ground Shrinking]. 

*Grrrt* The entire ground below the upgraded explosion bug immediately moves back towards the forest.
