Ocean Master

From the attack on Sebastian by the enormous Octopus to the Lizard Lord substituting on his place to fend off the tentacle attack of the Octopus, to all of them preparing for battle, they all took only about 10 seconds.

Though at this short time, the Octopus was not able to do much, it was able to attack. Seeing everybody gang up on it, it no longer held back, it revealed everything.

Sebastian was not able to count them all immediately, but he was sure that over 30 tentacles were released as they lashed out wildly in the water like whips.

Once again, despite attacking everybody at the same time this time, Sebastian was given special attention as 5 tentacles were sent towards him.

Already experiencing the power and speed of the tentacles, Sebastian who was not willing to experience it again reacted before it touched him.

[You have activated unique skill: Water Transmutation.]

[You have created a magic manifestation: Heavy Armor!]

Immediately after the magic manifestation appeared, it wrapped around his huge body, fitting in like it was custom-made by an extremely precise machine.

Boom!

The tentacles finally hit with force, spreading a large sound through the surrounding. The Heavy Armor suffered a visible depression, but it held sturdily like the ancient walls of China.

Seeing this, Sebastian heaved a sigh of relief. This magic manifestation did not disappoint him, it proved itself as his strongest and most mana-draining magic manifestation.

He was able to tide through the first attack safely, but the same could not be said about the other sea creatures on the battlefield that were attacked.

The Lizard Lord and the Mystery Pryer Shark were able to defend themselves, but every other creature on the battlefield suffered.

Bam! Bam!

The Crocodiles that were famed for their thick skin exploded like balloons after one hit from the tentacles, the weapon that wrapped around the tentacles made sure that those that survived didn't survive for long.

Every creature that suffered a direct hit died, exploding into a rain of blood.

Before the enormous Octopus could attack again, the Lizard Lord and the Mystery Pryer Crocodile did. Both of them attacked in ways that they were familiar with, which was with fire.

The huge Draconic Lizard rapidly swam closer before opening its mouth wide, unleashing a wide breath of raging fire towards the Octopus.

The Mystery Pryer Crocodile while also breathing fire, her magic power wrath mischief. The rocks in the seamount stirred on her orders, trying to tie the Octopus and restrict its tentacle movements.

Combining her water and wind magic, she formed a sharp combination like knives that tried cutting through the wildly lashing tentacles but the weapon around it protected it perfectly.

  Seeing this, she quickly improvised and directed her magic skills towards the main body of the Octopus. Before they could hit, a blood-red magic shield appeared which kept all the attacks at bay.

With the 2 strongest powerhouses in the battle being restricted so perfectly, all the others were cannon-fodder who could only die.

No creature on the battlefield dared to get close to their opponent, they all tried attacking with their fire magic from range but the effects were limited.

Combining so much fire made the attack frightening, but nothing could breach the magic shield erected by the Octopus. It was like it was indomitable, nothing could stop its slaughter.

  Every second, a Mammoth Crocodile and a Draconic Lizard died with their leaders being unable to take revenge for them.

  For Sebastian, he was powerful but his most important asset, his mana points were already almost depleted. 

Using it to maintain his Heavy Armor magic manifestation was already a stretch, he didn't dare try to create another magic manifestation.

His health was a little over 500 points now after using his rejuvenation skill, but he didn't feel safe at all as every second his MP decreased more.

Seeing this, he knew that waiting for a miracle would not work this time. Instead of waiting hopelessly, he instead decided to direct his brain to do more analyzing work.

As he analyzed, he noticed despite the intensity of the battle, the enormous Octopus never left its position to enable its attack to reach even further. It was like it was restricted to that place alone which was weird.

He tried to analyze another thing, but he could not as the voice that he heard the next moment left him at the point of despair.

"B-big bro, I'm dying". Verni called out softly.

The Great White Shark was currently bleeding severely, having suffered a tentacle attack that tore through his body completely. The passive effects of the Octopus's weapons were slowly killing him.

Only his strong vitality as a Great White Shark and his self-preservation skills were the main reasons that were barely keeping it alive.

Seeing this sight, Sebastian felt a ripping sound going through his heart, he felt like tearing his hair apart if he had one. 

He didn't feel scared yet since his HP was still slightly abundant, but since evolving to become a Megalodon, this was the first time that he felt so helpless in a battle.

He felt an urge to create another Heavy Armor magic manifestation and cover Verni with it to protect him, but he didn't have that luxury.

[Warning! Your MP is now lower than 10%.]

"Noooo!" Sebastian felt despair grip his heart.

Right now, he started regretting his decision to attack the Crocodile kingdom. As he regretted, only one sentence reverberated in his mind, 'there's always a price to any decision taken'.

A distance away, the Lizard Lord fought with rage now clouding his features. Despite all the effort that he put in, the Octopus's shield still held while his family members died like chickens in Christmas.

He felt the temptation countless times to rush closer and deal real damage, but he knew that doing that was equivalent to committing suicide.

He had no doubts that if the Octopus really caught him, death was his only fate. Right now, only one thing dominated his mind. "Octumpedam recovered even further than the last time".

A few meters away, the Mystery Pryer Crocodile experienced the same. Pushed by despair, from attacking, she switched to defending with her omnipresent magic to help more Crocodiles survive the onslaught.

She already gave up winning, now all she focused on was delaying the inevitable. 

Sebastian observed the battle one more time and discovered that help was really coming from nowhere. "I thought I was a protagonist; I can't die like this. System, do something".

[There's nothing that can be done, host has full control of his destiny.]

Seeing this, Sebastian felt even more horrified and scared. Perhaps, due to his strength, he already gradually forgot that he was once a human but it was at this moment that he was brought back to reality.

He may be a powerful Megalodon now, but at the core of his heart, he was still a human. He had emotions, he knew fear, he knew despair.

Boom!

Another special attention attack from the enormous Octopus finally did it.

[Warning! Your MP has been depleted.]
