Versatile Mage: I was reborn as Mo Fan

However, this fierce tower defense battle did not last long.

"Rumble!!!"

Just when everyone breathed a sigh of relief, thinking that they could temporarily curb the Siren's crazy attack, the calm sea surface was suddenly stirred by an invisible giant hand, and the sea water rolled violently, forming huge whirlpools.

“Whoa whoa whoa!!!!”

Immediately afterwards, an extremely huge shadow broke out of the water, like a black mountain rising from the bottom of the deep sea, rushing towards the seawall with overwhelming momentum.

"boom!!!!"

"Boom!!!!"

There was a deafening noise, as if a massive thunder exploded in the ears, and the first seawall instantly exploded under the impact of the giant shadow.

Solid stones flew everywhere like cannonballs, with huge rocks hitting the mages directly. The mages couldn't dodge in time and were hit instantly, with blood splattering on the spot.

At the same time, huge waves were stirred up as high as tens of meters, like a wall of water, pressing towards the surrounding defense facilities and soldiers.

Most of the high-level mages on the seawall were not spared in this sudden attack.

Only a handful of people managed to escape thanks to their powerful magic and quick reactions.

When the smoke and mist dissipated a little, everyone finally saw the appearance of the mermaid.

It is huge, over a hundred meters long, with a streamlined body covered with a layer of dark purple scales. Each scale is the size of a millstone and sparkles with a metallic luster, like an indestructible armor.

On its head, a pair of huge eyes emitted a faint green light, like two will-o'-the-wisp fires, revealing endless cruelty and greed.

Its mouth was extremely large, taking up one-third of its head, and was filled with sharp fangs. Each fang was as tall as a person, arranged in a triangle, and extremely sharp. They were covered with sticky saliva and emitted a disgusting stench.

On its back stands a row of huge fins, the edges of which are like saw teeth, flashing with cold light.

Its tail is thick and powerful, like a huge shovel. A slight swing in the sea will stir up thousands of waves.

The most terrifying thing is that there are five thick tentacles extending from each side of it. Each tentacle is thicker than an adult's waist and is covered with basketball-sized suction cups with sharp serrations on the edges. These tentacles twist like giant pythons, emitting powerful demonic power fluctuations.

“Ah~~~!!!!”

The siren howled towards the sky, the sound waves were like surging air waves, wherever it went, huge waves of more than ten meters high were raised on the sea surface, even the birds in the sky were dizzy and fell down one after another.

With this roar, the inky black sea water surged violently, and more sirens of various shapes emerged from the water like a black tide, rushing towards the broken seawall with their fangs and claws.

“Evacuate the second line of defense!!!”

Just as everyone was still in shock, a powerful voice exploded in everyone's mind like a huge bell.

This voice, which carried the dual magic of sound and mind, not only gave clear instructions, but also was like a warm current, dispelling the fear spreading in the mages' hearts and quickly bringing them back to reality.

The surviving wizards woke up as if from a dream, and cast flying magic, rushing towards the rear.

Looking back, the broken seawall had been completely occupied by the sirens.

These sirens were like crazy destroyers. Some of them scratched madly with their sharp claws, while others sprayed corrosive venom. The hard seawall stones collapsed one after another under the rampage of the sirens.

Even though these rubbles were made of special materials, they were still no match for the massive sirens. In just a few minutes, the seawall completely disappeared, as if it had never existed on this coastline.

The Magic City Base City spent countless resources to carefully build three lines of defense, each of which was infused with the most advanced magic technology and was indestructible. But no one expected that the first line of defense would fall so quickly.

Above the second line of defense, the atmosphere was so heavy that water could be squeezed out of it.

Commander Su Lie stared at the sea with his hands behind his back, his knuckles turning white from the exertion.

Seeing the siren approaching, he decisively ordered: "Activate the defensive barrier! All mages, get ready and follow my command!"

As soon as he finished speaking, a transparent magic barrier slowly rose up and covered the second line of defense.

At the same time, the mages took their positions, with lights of various colors flashing around them, ready for battle.

The swarm of sea monsters swept in like a black storm and soon collided with the defensive barrier of the second line of defense.

In an instant, magical light and demonic power intertwined, and the explosion was deafening.

A gigantic crab-shaped sea monster waved its two huge claws and smashed hard into the barrier. Every attack caused the barrier to shake violently, creating ripples.

In the fierce battle, magical light and demonic power intertwined and collided, and the sound of explosions continued.

Su Lie's eyes were sharp as a torch, always paying close attention to the situation on the battlefield.

At this moment, he keenly noticed that the roaring giant siren was slowly approaching the second line of defense with heavy steps.

This mermaid is huge, like a moving black island. Wherever it passes, the sea water churns violently, forming huge whirlpools.

The surrounding sirens seemed to have received orders, and gathered around it like stars surrounding the moon, rushing towards the defense line with great momentum.

Su Lie's heart sank, and an ominous premonition came to his mind.

Ever since this siren easily destroyed the first line of defense, it became Su Lie's main target.

In the previous scene, the powerful impact of the Siren directly broke through the solid seawall and protective magic circle. Its power was so strong that it was terrifying.

Su Lie knew very well that this siren would be the biggest threat facing the second line of defense.

Once the magic circle is broken by it again, the seawall alone will not be able to stop it, and the demon city will be completely exposed to the iron hoof of the mermaid.

But he couldn't just charge out like Zhang Sen did. Regardless of whether he was the opponent or not, once he charged out, the command of the entire defense line would instantly fall into a passive state.

It’s not that Zhang Sen is irresponsible, it’s just that, given the situation just now, he had no choice but to stand up.

Even now, the power of the magic circle is still being exerted. It can be said that his contribution is not small.

The magic circle here does not need to do this, because the first line of defense magic circle has not been closed yet, which means that it is still outputting continuously.

So, as long as that huge monster was there, he couldn't move.

But it didn't take long for the Siren King to come here. Even the destruction array could cause little damage to it.

It was as if it was carrying dense firepower and moving straight forward with no obstruction at all!
