Yulia stood on top of the outer wall of the city and saw the swarm of Sea Creatures below her.

Currently, there are five types of sea creatures that have been trying to invade them. The first type is the weakest fishmen or humanoid fish and was very weak against Fire Elemental Attacks but incredibly resistant against water and ice elemental attacks for obvious reasons. These fishmen would normally use their sharp teeth and water bullets for their main attack. They would sometimes use spears and shells as a shield but there weren't many of them probably because of the scarcity of resources as well.

The second type is the humanoid seals which are incredibly tough and bulky. Piercing them with sharp weapons would be very difficult unless they are using an item at a Unique-Rank or above… These creatures also have slow movements but their punches, headbutts, and kicks would easily create a crack in the city walls that has been repaired numerous times.

Sending at least an ArchKnight to stop their advance is necessary.

The third type is the one that Yulia captured and brought to the interrogation room and is very dangerous because of its toxic fumes… Luckily, even the other sea creatures would die from these toxic fumes so they wouldn't normally use it unless they are in a dire situation.

The fourth type was the humanoid sharks… Their numbers weren't that huge compared to the first type but they were twice the size of an adult human so they can be easily seen. Their sharp fins and fangs were their main weapons aside from their powerful physical strength… It is a good thing that these creatures weren't adept at using water techniques and only uses their physical attributes in battles.

Apparently, Yulia was able to sense that these sharkmen have a huge amount of mana but they weren't capable of controlling it… which is obviously a good thing for their Mage Battalion.

The fifth type, on the other hand, was no longer a humanoid one but they are still an intelligent Sea Race, they were the large purple octopus that would normally be used as mounts of these sharkmen.

If Yulia can have a choice, she'd rather face the toxic fishmen than these large octopuses that can move on land.

"Tsk… There are more sharkmen than before… I heard that many ArchKnights were injured in the previous fight, are they all healed now?"

Yulia asked after noticing the alarming number of enemies this time. Their Mage Battalion can only work properly if the frontline composed of Archknights and Magic Knights can withstand the assault of the enemies.

As long as this line of defense is not broken, the Mage Battalion can bombard these Sea Creatures with their Elemental Arts and sweep through them.

"There's no need to worry about their troops, Yulia… I heard that they've been stockpiling the potions from our city… They should have more supplies of recovery potions than us…"

"Haha… Is that so? Then there's no holding back… Let's quickly end today's invasion using our new formation." Yulia said as she looked at the 20 squad leaders of their Mage Battalion.

Their faces showed a hint of excitement as they were about to use a high-level Fusion Art. Furthermore, this is not a simple fusion art like what the other talented magicians can do.

Fusing Earth and Fire Elements to summon a Blazing Meteor is called Fusion Art. It is the same with Wind and Water to create a Storm Burst. They were both Fusion Art and they are normally done by genius Mana Practitioners to create a stronger elemental art against opponents of similar level.

However, what they were about to do is a Fusion Art through the help of twenty or so Magicians led by Yulia!

This is only possible thanks to her mastery over the Darkness Mystic Eye!

The entire Tudor Kingdom has been very wary of this special Mystic Eyes before because of how it could grow stronger the more you cultivate it.

Yulia may just be categorized as an Elite Magician if she has only mastered two tiers of this technique. However, now that she mastered its fourth tier, she can easily go toe to toe against the older Grand Magus or those Penta-Casters and above.

Clang! Clang! Clang!

The sounds of battle at the front lines have finally started. They were no longer using the Barrier Formation since it will only be destroyed in just a matter of time… Instead, they would just save the energy used to create this barrier and use it to guide the sea creatures on their path to the fully-armored Archknights and Magic Knights waiting for them.

Boom! Boom!

Several bodies of sea creatures would fly all over the place as their limbs and weapons were easily destroyed by a Magic Knight's wave.

The sea creatures would scream in pain or shout in anger but the Knights would just ignore them. After so many battles, they learned how to properly save their energy… There were no wasted actions as they move steadily to cut them off.

However, this will only continue when dealing with the first and second types of Sea Creatures.

Once the Toxic Race and Shark Race come, they would have to depend on the Magicians while they hide behind their shields and armor.

Clack… Clack… Clack…

Soon, the sounds of moving octopuses can be heard as the second batch of invaders started moving forward.

It was at this point that Yulia gave her orders.

"Let's begin!"

Soon, ten Archmages with mastery over Fire Element and eleven Archmages with mastery over Earth Element worked together to cast elemental spells.

They formed a circle like they were in a ritual while Yulia stood at the center of it.

The Archmages did not release their Mana Arts and only formed it within their casting tools… Yulia stood there silently while her eyes were closed as she was preparing to activate her Mystic Eyes' fourth-tier ability…

After a few more seconds as the sharkmen are getting nearer to the Magic knights, she finally opened her eyes and gave another order…

"Now!"

As soon as she said this, her eyes turned completely black as the Mana Arts of the Archmages surrounding her were absorbed by her Mystic Eyes! It created strong Mana Fluctuations that scared even the Knights on their side!
