Threat from the Sea (III)

Isaac looks at the monster in front of him with a frown on his face. With the Crystal Serpent's help, he knows that the wall they built will not survive the fight. He needs to take the Serpent away from the wall.

"Lucina! You will come with me. We will keep that serpent away from the wall."

"Yes!"

Isaac then looks at the captain he brought with him before saying.

"You! You will be the one leading the people here. Hold the wall as long as you can."

"Yes, my lord!"

Isaac jumps down from the wall and lands next to Lucina.

"Let's go."

"Right behind you."

Both Isaac and Lucina begin to run toward the serpent with their enchanted body. Isaac swung his spear right and left, killing the monster that was coming their way. When he saw Xherzul chanting in the distance, he activated his star rune.

"Twinkling Star!"

As the spell's name is being invoked, a beam of destruction rains down from the sky and kills the Xherzul that try to use their magic on him.

Next to him is Lucina, who is also killing the monster that is coming their way. However, unlike Isaac, who is running around, Lucina is flying above the ground using her mastery over the wind. While Isaac uses his Star Rune to destroy the enemy in the backline, Lucina uses Rage Rune's power.

"Explosion!"

As the name is invoked, a massive ball of flame appears on top of the Crystal Serpent and then drops on top of its head. As the ball of flame touches its head, the ball explodes. A few seconds later, as the dust vanished, they could see the Crystal Serpent's body has a burned mark on them, but overall it was fine.

The Crystal Serpent roars in anger and begins to charge at the couple who run toward it. Seeing the incoming serpent, Isaac activated his pale gate rune.

"Summon! Bull of Heaven!"

The sky begins to split, and coming from the sky is a massive bull with a blue skin descent from the sky. When the bull looks at the Crystal Serpent, it roars and charges at the serpent, like a bull seeing a red cloth.

The bullhead hit the serpent's head and threw it away back to the sea. However, instead of leaving it there, the bull charges a massive lightning bolt from its horn and fires it at the serpent. The lightning bolt hit the sea and created a massive lightning dome in the middle of the sea.

A second later, the lightning is gone, and the serpent nowhere to be found. The soldiers begin to cheer up, but Isaac deepens his frown. He knows that this is not finished.

True to his prediction, two Crystal Serpent appear from the sea and bite the Bull of Heaven. This is the special power of Crystal Snake. It can split itself every time it is killed. Each time it splits itself, it will double its strength and durability.

It needs to be killed after beating it four times. People can kill it after you beat all the sixteen of its split body. There is a reason why this monster has the title of 'Fake A-rank Monster.'

He can use his Final Bell spell and kill this monster, but he doesn't know if they will split once again. He wants to try it, but Isaac doesn't want to risk it. He really regrets using his True Death spell in his pocket dimension.

Isaac also already tried to use his Finger of Death to attack the Crystal Serpent, but it was not active, which means that this creature has an affinity toward death. For now, he needs to kill it until it reaches the stage where it splits itself into sixteen.

"Shredding!"

Isaac snaps from his thought when he hears Lucina activated her Cyclone Rune and creates a massive tornado under the serpent. The tornado strong enough to pick the Crystal Serpent up in the air. Seeing an opportunity, the Bull of Heaven releases a large amount of lightning from its body and electrocutes the serpent.

However, instead of making a wound on the serpent, it feeds the monster with power. Sadly for the monster, the lightning they can absorb has a limit, and when they feel they reach their limit, they release their fang and get thrown away by the tornado.

"Fire Storm!"

Seeing the serpent get taken away by the tornado, Lucina activates her Rage Rune and calls a massive fire from the ground. Combined with the tornado, it became a flame tornado of death. The fire burnt the Crystal serpent into ashes.

However, before they could even take a break, a dark light appeared where the serpent burned to death, and as the dark light shone, there was four Crystal Serpent ready to fight. This time, their size is doubling up from the original.

"Summon! White Serpent!"

The sky began to change once again, and this time it released a massive snowstorm on the area. A second later, an eastern-style dragon appeared from the sky. It has a light blue scale around its body. The scale around its head, on the other hand, colored dark blue. To its side, it has a white fin on top of its body.

However, Isaac did not stop there. He takes out two Pokeball from his inventory and throws them away. Coming from the Pokeball is Tyranitar and Steelix. It was King the Tyranitar and Laus the Steelix.

"King! Laus! Evolve!"

After releasing both King and Laus, Isaac takes out another item from his pocket dimension. It was a Mega Evolution stone. He then throws it at both King and Laus. Both of them begin to change in size and shape.

"Attack! Help the bull and the white serpent!"

After hearing his command, both King and Laus begin to attack the Crystal Serpent. While letting the summoned creature fight against the Crystal Serpent, Lucina and Isaac fight against the minion that keeps coming at them.

"Twinkling Star!" "Explosion!"

After casting their spell, Isaac raises his spear and begins to attack monsters that successfully dodge his spell attack. He thrust his spear, and when he saw his spear being blocked by a shield, he activated the rune on his spear, and suddenly it released lightning from the tip of its spear and drilled the shield hitting the Lasu-Valu right in the head.

Isaac then blocks the incoming attack from the right as Lasu-Valu jumps toward him with its pear in hand. While busy blocking and attacking the incoming attack from all the Lasu-Valu, Isaac did not see the Xherzul ready to cast their spell. A second later, they fired their spell.

However, before the spell could reach Isaac, a golden shield appeared in front of the spell and blocked the spell, protecting Isaac from it.

Isaac nods his head at Lucina before throwing one of the Lasu-Valu and creating a torrent of fire that burns the monster in front of him.

While both of them have massive stamina, they begin to feel their body exhausted, fighting all the monsters that keep coming at them. Their tiredness is gone when they hear a victorious shout coming from both King and Laus.

They are finished fighting against the Crystal Serpent, and Isaac can see the familiar dark light begin the descent from the sky and float above the Crystal Serpent's corpse. Isaac quickly calls back both King and Laus then stores their Pokeball inside the pocket dimension.

He also de-summon both the Bull of Heaven and White Serpent. He has a plan to fight against the Eight Crystal Serpent. When he sees the dark light begin to shine, he activates his Pale Gate Rune once again.

"Summon! Emperor Vessel!"

As eight Crystal Serpent appear from the dark light, Emperor Vessel appears from where Isaac stood. The Emperor's vessel is a massive pirate ship. Its length is around two hundred meters long, and its height is around fifty meters high.

"Fire!"

The ship's side begins to open up and reveals a massive amount of cannon being mounted on the ship. A second later, all of them begin to fire its shell at the Crystal Serpent. However, unlike any other ship where you need to reload, this ship did not reload, and its firing rate is like a Gatling gun.

The firework lasted for ten minutes, and when it stopped, there was nothing left of the Crystal Serpent. Once again, the ball of dark light appeared on top of where Isaac killed the Crystal Serpent.

Just like before, Isaac activated his Pale Gate Rune.

"Summon! Void Watcher!"

At the same time sixteen Crystal Serpent appear, there is a massive skull appearing beneath Isaac. Lucina, who knows the firepower of that skull, decides to run away from her current location. After she is far away from the beach, she creates a barrier around herself.

The skull opens its mouth and fires a beam of death. The attack lasted for fifteen seconds, but it was enough to kill all the Crystal Serpent at once. After doing its job, the skull went back to where it came from, the void.

Isaac takes a deep breath and feels that his mana reserve has been cut by half. The first time he cast that spell, he almost went unconscious. Seeing the big guy is done, he sees the battlefield is only filled with a C to B+ monster.

"Let's finish this."

Isaac takes another deep breath before activating his Pale Gate Rune once again.

"Summon Gate Guardian!"

After he says that, a thousand a massive centaur appear in front of him. Unlike the ten summon where he can keep them indefinitely, I can only maintain this type of summoning for three hours, but it was enough.

"Attack!"
