After entering this room, Carl immediately saw the body of a mermaid.

The poor guy collapsed on the ground, and a large conch fell beside him. The blood stains on the clothes on her chest showed the cause of her death, and the compass in Karl's hand also pointed to the wound on her chest.

Knowing that this was where the clues were, Karl immediately went up to help the body, and then began to look at the wounds on her chest.

Regardless of her broken shell decoration, there was a wound of about five centimeters piercing through the mermaid's heart at the heart. Because she was in the sea, the area around the wound was different from the blood-stained clothes, but it was very clear.

He showed this fatal injury in front of Karl.

Based on the knowledge he had previously learned at the trial agency, Karl could directly determine that a sharp weapon had penetrated the mermaid's heart directly, and then the murderer quickly pulled out the weapon without further exacerbating her struggle before her death.

Wound.

Just as Karl was studying the corpse, Naia on the side also spoke:

"This should have been a stab wound with a sword, and the wound appeared earlier than the wound on the little guy's mother's body."

The little one in Naia's mouth refers to Iida, and the mother refers to the mermaid queen.

The evil god's judgment was naturally not wrong, so Karl also confirmed that the murderer was a guy who used a sword as a weapon, and at the same time, he should be the last one to make a move in the hall.

"Mr. Carl."

At this moment, a familiar voice suddenly came from the door of the room.

It was Ida who came over, and behind her was the red devil Barry as a guard.

At this time, the mermaid princess' eyes the color of the sea were full of determination. The sudden bad news did not knock the mermaid princess down, but made her awaken to something different.

Karl could feel Iida's emotions from this look. There was indeed something different in her spirit and will.

Looking at Karl who was inspecting the body, Iida continued:

"The shell in the previous hall was where we stored the [Sword of the King]. The murderer... the murderer's goal was probably this artifact."

When she said the word murderer, Iida's tone was obviously trembling, but she quickly suppressed this emotional fluctuation, took a deep breath and continued her words smoothly.

"I have also seen the wound on Mother's chest. Something penetrated her chest and then suddenly burst open."

"Although it can be seen from her movements and expressions that my mother was aware of the enemy's arrival, she had no chance to fight back. The opponent's movements were definitely very fast."

After hearing what Iida said and combining it with some previous information, Karl immediately had an unpleasant inference in his mind.

So he looked at the compass in his hand and immediately confirmed in his mind.

After asking the compass to point to different things three times, the pointer in front of me did not tremble at all and pointed steadily in the same direction.

Faced with this result, Yu Karl also made a rough inference in his mind.

What he was thinking about just now was:

The location of [King’s Sword];

The location of the murderer who attacked the mermaid home;

And the location of the third sword.

Because from the time judgment given by Naiya, Karl knew that the mermaid in front of him was killed before Iida's mother. The sword wound on her chest showed that the weapon used by the other party was a sword, and based on the size of the wound,

You can also know that the size of the opponent's weapon is similar to your own [Siren Sword].

The target is one of the seven swords, and with this weird ability to destroy cities, Karl has reason to suspect that the murderer is someone who is collecting the seven swords like them.

Then I tried it with a compass, and this is exactly the result.

That is to say, a man with a sword attacked the mermaids' home, and then took away the [Sword of the King] they owned.

Realizing the appearance of competitors, Karl's movements did not stop. He immediately began to ask the compass for the locations of the other swords.

Fortunately, the result this time was pretty good. In the remaining four times, the direction of the compass pointer changed to varying degrees. This at least meant that the other party was not that fast yet, and it was just a handful more than him.

After figuring out the problem, Karl looked at Iida in front of him again and said:

"Iida, can you tell me what power the swords of kings that you mermaids possess have?"

"We may have to fight each other next, so it's better to know in advance."

"No problem." Hearing Karl's question, the mermaid princess in front of her immediately nodded and replied: "As long as the [King's Sword] hits one part of the body twice, the injured person must complete the [King's Sword]

A request from the holder.”

…

It's really a simple and crude ability.

Compared to the [Sword of the Siren], which is forced to sleep as long as it hits, the [Sword of the King], apart from the requirement of hitting a location twice, has a unique ability that is much stronger than the [Sword of the Siren].

Although it may not be very effective for those who are agile or defensive, in this underwater world, as long as you chop twice in a row on a huge sea beast that is not very clever, you can immediately complete the enslavement behavior of controlling the other party.

Having mastered this level of power, it's no wonder it's called the "Sword of the King" by the mermaids.

"Mr. Karl, can you accompany me to continue searching?" In reply to Karl, Iida also made her own request.

"I want to see if I can find any survivors."

At this moment, the beautiful girl had a trace of hope on her face, obviously hoping that Karl would agree to her request.

"Of course, no problem." Karl replied immediately.

Although the situation outside the city may be hopeless, there is still a slim possibility inside this coral reef. After all, the people here were killed, not killed by that weird force.

There's no telling if we'll find the lucky one that the other party missed.

So accompanied by Iida, they began to search among the coral reefs.

The building that was supposed to be a charming building was now filled with the smell of death. Although Karl confirmed that there were no survivors here after using the compass, he still cooperated with Iida to conduct a search.

As a result, after they walked a full circle and returned to the hall where the body of the Mermaid Queen was located, Iida's eyes were brighter than before.

"Did you find anything?" Karl asked curiously.

"My sisters...my sisters!"

Looking at Karl's face, Iida showed a very excited expression.

"There are no bodies here, they are still alive!"

Upon hearing Iida's words, Karl immediately took out his compass and asked in his mind: "Where are Iida's sisters?"
Chapter completed!
