Reiko fires a series of Flame Lances for good measure.
When the first shot lands, a huge Death Sea Serpent breaks the surface of the sea, and its scythe rises up.
"Flame Buster!"
At that moment, the advanced flame magic blasted the Death Serpent's head off.
"One!"
Perhaps sensing that the leader had been killed, three more Death Serpents emerged from the surface of the sea.
"Flame Buster! Flame Buster. Flame Buster!"
Reiko fires a series of flame magic at three of them. Two more are blown off their heads, exposing their wreckage to the waves.
That's three!
However, the other one sensed her presence and dove into the water, so the third flame buster was a missed shot.
Jin, who was watching this, said,
"You dove into the water. Watch me, I'll flush you out."
He then executes the tactic he had planned.
"Acoustic sonar!"
It is an engineering magic that uses ultrasonic waves to examine the internal defects of objects, etc. If the strength of the ultrasonic waves is increased, it can affect underwater creatures.
Jin fired ultrasonic waves at the maximum intensity into the sea ahead of him.
Immediately after that, more than ten Death Sea Serpents appeared as if they were fleeing from the sea. Fish large and small, stunned by the aftermath, also floated in the vicinity.
Five Death Sea Serpents were reduced to rubble by the continuous fire magic.
"Eight of them now..."
However, the escaped Death Serpents dive into the sea again.
Then Jin said..,
"Reiko, I'll flush them out again, this time attack them with lightning magic".
"Yes, sir.
"Okay, here we go. ...... acoustic sonar!"
The Death Sea Serpent is hit again with another ultrasonic shock, and it rises up out of the water,
"Thunder Rain!"
Reiko showered the Death Serpent with a thunderbolt-type superlative magic.
The Death Serpent was hit by the lightning, and it seemed to faint and floated on the sea with its belly showing.
"All right, I'll finish him off later! Again!"
Jin fired his acoustic sonar at full power. Reiko pelted the floating Death Sea Serpent with Thunder Rain.
More Death Serpents were knocked unconscious and floated away.
That's half of them.
But there are too many! Fall back!
Reiko is in danger, but Jin is not. Reiko retreats quickly.
Two Death Sea Serpents have realized that the small boat in front of them is the source of the danger.
The Death Serpent is superior in instantaneous force and closes the distance instantly.
Reiko was too occupied with the outer ring to intercept them.
When the jaws of a single Death Serpent was right in front of her.
"Water Jet!"
Jin unleashed his magic on the approaching Death Serpent. The blade of water, which exceeds the speed of sound, cuts off the Death Serpent's head without a second thought.
Jin and the others are drenched in the gushing blood. But in the meantime, another Death Sea Serpent was approaching.
"Water Jet!"
Once again, Jin swung his water jet. This time, he was a little farther away, so he was not splattered with blood.
"Father, what was that?"
Reiko asked in surprise.
"Oh, it's an engineering magic <>. It can even cut Adamantite!"
"As expected of your father!"
Reiko looks happy even at a time like this.
In the meantime, I was able to keep my distance from the Death Serpents. There are about 15 of them moving now.
"Is it not effective from this distance? Water Jet!
Jin's powerful water jet sliced through the bodies of two Death Sea Serpents, cutting them in half, but the remaining 13 serpents created a curtain of water to block it.
"d*mn, I guess they are strong against water."
The water current of the Water Jet could penetrate through the water curtain created by the Death Serpent, but its power was weakened considerably and it bounced off the Death Serpent's scales without damaging them.
The remaining thirteen serpents went berserk and shrank back to attack Jin and the others. Their movements stop for a moment. Then..,
"Mana Explosion!"
Reiko's most powerful offensive magic has exploded. This magic can annihilate only those who have magic power, but it is necessary to aim at the magic core with pinpoint accuracy in order to suppress the power of the magic.
Otherwise, the surrounding magic power will cause a detonation, and it will be a terrible thing.
Aside from that, eight Death Sea Serpents were blown up by a single "Mana Explosion".
The one that was floating unconscious was also caught up in the explosion, making a total of seventeen Death Serpents blown away. Now there are only five left alive.
"Whoa! It's shaking!"
The small boat was indeed rocked by the aftermath.
"Once again, ...... is a little too close."
Reiko refrains from another Mana Explosion.
For Jin's safety, she took precautions. Then the remaining Death Serpent approaches.
"Laser!"
This time Jin's magic was released.
An intense red light pierces through the Death Serpent's head. If it hit the water curtain, it evaporated instantly, and pierced through the hole in the Death Serpent.
In the blink of an eye, all five Death Serpents were vanquished. Reiko saw this,
"Father, is that engineering magic too?
"Yes, it was a spur-of-the-moment operation, but it worked. It was just an application of light magic.
Light. It is a magic used to illuminate your hand or to find something in a dark place.
"It's just that the light is amplified so intensely and the waves are aligned (coherent).
It is possible because it is magic, but in reality it would require a large apparatus. However, Jin had both the knowledge of modern Earth and the knowledge of a magical engineer, the MagiCraft Meister.
A fusion of science and magic. It is a path that leads to a higher level than that which the previous Magecraft Meister, Adriana Barbora Zetsi, had set out to achieve.
"You've done it, Father."
Reiko said as she put an end to the floating Death Sea Serpent.
"Well, I guess I'll have to put an end to it.
Reiko, who had no such feelings, took care of it as if she was working without any hesitation.
"Are you done?"
"Yes, I don't feel the magic anymore."
On the quiet sea, Jin washed away the returned blood with water magic. Like Reiko, his clothes are made of magical material, so they will be clean in no time.
"Well, shall we go back?"
"Yes, father."
Jin and the others began to return, slower than when they had arrived.
