Just became an evil god and was summoned by the saint.

Chapter 158 Objective: Complete Strategy

Celia manipulated the puppet to pick up the precious bead and bring it over here.

Upon closer inspection, it turned out to be not a bead, but an eyeball, an eyeball with a texture like a gemstone.

Ross said, "This is the Eye of the Siren. It has the ability to see far and wide and can also see through enemy moves. It is especially effective against water-type monsters. It can be used alone or embedded in a staff to increase magic power and the power of water and ice spells. Don't embed it in melee weapons, otherwise the Eye of the Siren will be corrupted."

Celia raised the Siren's Eye: 'Embedding an eye into a staff...it just feels so strange...'

"Idiot, why don't you use magical materials to cover the eyeball and make it look like a magic crystal?"

Celia: "..."

What a clever way to deceive oneself.

Everyone else crowded around to examine the Siren's Eye more closely.

Benovia pondered for a long time before saying uncertainly, "This might be the legendary Siren's Eye. It is said that the Siren, born in the deep sea, has eyes that can see through the weaknesses of all spells and can see ants thousands of miles away. It seems that it could be used as material for a staff, making water spells ten times more powerful."

Celia: "?"

She looked at Benovia, "Which ancient book did you read this from?"

“Let me think…” Benovia fell into deep thought, then said, “It’s an ancient book that’s been preserved for over a thousand years. I think the name is ‘The Little Mermaid’.”

Ross rolled his eyes: "That's a fairy tale, and a distorted one at that."

The version of "The Little Mermaid" in this world is different from the original fairy tale. According to the background story, it was created by a bard based on fragments of conversations with fishermen, portraying the siren as the daughter of the sea and a powerful creature comparable to a god.

After all, it's a fairy tale, so the more exaggerated the better.

After understanding the situation, Celia said, "If the Eye of the Siren possesses such powerful abilities, why were we able to kill it so easily?"

Benovia said apologetically, "The authenticity of ancient books can no longer be verified. The siren, as a monster that was active a thousand years ago, has now disappeared without a trace and is unknown to people. I also find it difficult to identify the purpose of its eyes. It needs to be taken to the school for authentication."

Celia smiled and relayed Ross's words, letting them understand the function of the Siren's Eye.

The Eye of the Siren will remain with Celia for now. Once we return, we'll have it appraised by our mentor to confirm its value before redistributing it.

They would never hand over something so precious.

“The leader has finished fighting, and we should go back now, but it’s not morning yet, and there are still unpredictable dangers outside. How about we stay here until sunrise and then go back?” Celia asked for everyone’s opinion.

The three shook their heads, indicating that they had no objection.

After defeating Terksi, it was already past midnight, and there wasn't much time left before sunrise.

After such a difficult battle, especially after being repeatedly assaulted by the screams of Telkis, their condition was not good, and with their limited vision, they were no longer able to withstand the onslaught of a large number of monsters.

“However, this cave isn’t safe either. If the monsters are controlled by the owner of the lighthouse and block the entrance, we’ll be trapped like turtles in a jar,” Anke said.

Celia nodded: "That's a possibility. I'll go to the cave entrance to prepare and set up some magic arrays to block the monsters from detecting us."

After saying that, she walked towards the cave entrance.

Under Ross's guidance, Celia used whatever materials were available to collect the scattered magic crystals and other materials outside, engraved runes on them, and placed them around the entrance of the cave.

"This magic circle is a concealment magic circle specifically designed for the entire ruins. All the materials used come from the monsters themselves, so other monsters, including the lighthouse owner, will regard it as one of their own, thus preventing the monsters from blocking the entrance."

"We're setting this up right under the lighthouse owner's nose, won't it find out?"

“No, its eyes are only on the navigation light. As long as the navigation light doesn’t shine on it, it won’t be detected,” Ross said with absolute certainty.

He didn't leave empty-handed when he entered the lighthouse.

Although it is still uncertain which 'old friend' the lighthouse controller is, they have already learned a great deal about him.

This includes its method of observing its surroundings from the top of the tower, where only the lighthouse's navigation light has become its eyes.

However, simply spotting it is not enough. To influence others, they need to look directly at the beacon light in order to cast a spell through their eyes and affect them.

Yes, it's utterly useless.

This is probably a sacrifice that had to be made in order to limit high-level mages.

If it weren't for this, the Lost Lighthouse wouldn't be an ancient ruin that's constantly being attacked by mercenaries, yet it hasn't been breached to this day.

After setting up the concealment array, Celia returned to the cave and saw Benovia and the others looking at the demon eggs on the mountaintop, discussing whether or not to shoot them down.

Celia couldn't help but ask, "Don't you guys get any rest?"

Benovia said, "How can we possibly rest peacefully in a place like this? There's not much time left until dawn. Let's wait a bit longer and go back to rest."

Anke nodded and said, "That's right. Although coming in was an accident, we just happened to complete the trial task assigned by the school. We can arrange things however we want from now on. It doesn't matter if we take a little more time."

After investigating the cave and observing Phil's state after purification, they determined that the siren named Telkis was the core of the pollution spread, producing monsters for the lighthouse.

Every night, these monsters are released to ravage the world outside the lighthouse with pollution, thereby influencing the outside world and gradually drawing it into the lighthouse's territory.

Celia pouted: "Are you really satisfied with this?"

Benovia and Anko exchanged a glance and immediately understood what Celia meant.

"Celia, do you mean to..."

“Yes! We’ve solved the source of the pollution spread so quickly, and it’s only the second day. There are still 58 days left in the two-month trial period. We can’t just go home in 58 days, can we? We might as well try to see if we can clear the Lost Lighthouse.”

"Although I also have the idea of ​​clearing the Lost Lighthouse, the boss outside the lighthouse almost wiped us out. I don't think we are currently capable of going deep into the lighthouse."

"That's easy. Use a month to prepare and improve your strength. Then come back to conquer the enemy. A month should be enough time to improve your strength, right?"

The two exchanged a glance and nodded. Benovia said, "That's enough, but we need to consult Phil and Doris. Let's wait until they wake up."

Phil was still meditating with his eyes closed, trying to purify the impurities in his body.

“Alright.” Celia found an open space to sit down and entered a meditative state as well.

The cave fell silent as people waited for time to pass.

Meanwhile, inside the school camp.

Many of the mentors leading the teams were extremely anxious.

"Haven't they found them yet?"

　I'll take a nap first, and write more when I wake up.
