After that, Lydia led Lyrventh to learn a lot of things. This was the first time he saw everything, including the humans. So, she taught him all the body parts before moving to all the objects around them.

Since he couldn't see, she didn't let him do anything previously. But with this, he should know about the object around him.

It was a truly good experience for Lyrventh.

It truly made Lyrventh realize how important the deal was.

As expected, the next day, Lyrventh enthusiastically informed Theo about all the things in their surroundings. Even if it was something unnecessary, he would inform Theo.

Of course, Theo didn't mind listening to all the details. After all, he didn't know what kind of clue the God of Mischief had left behind.

Seeing how the two kids survived in this place even made him doubt their existence. He thought the two kids were the clues the God of Mischief had left behind. All he needed to do was to use these two kids to find the real clue.

At the same time, the two kids were simply worth too much to the point he couldn't ignore them. Lyrventh's enhanced hearing became even better because he was blind. That way, it made him rely on his hearing a lot.

And seeing how the kids grew up like this despite listening to all kinds of sounds, it was clear that Lyrventh had a strong heart and mind like his sister.

In the end, Theo decided to take them to his base when Maya opened the airline.

Lyrventh had also become grateful to Theo. Every night, he allowed him to see the world. Even though it was ruined, this was the first time he saw them.

All he could think was how beautiful it was. And due to the fact that all the people and monsters in the city were gone, it became quiet. It was perfect for him since he could rest his ears.

During that time, he learned a lot under the guidance of his sister. Lydia wanted to show him how beautiful the world was.

She didn't care about the apocalypse and all these ruined buildings, she just wanted to show her that they were living in this place, so they had to enjoy it.

This kind of positivity was hard to come by. If he left Lydia to Rea, she would surely grow up as a beautiful and energetic woman. All that remained was Lyrventh. He had to take care of Lyrventh personally due to the enhanced hearing.

There was no way his people wouldn't talk about him at all. Even if they didn't do it immediately, they would slip up sooner or later.

By keeping him with him, Theo could maintain his state of mind. However, it didn't seem he could make Lyrventh his disciple.

Although his enhanced hearing was useful, Lyrventh couldn't get stronger anymore. He might be able to upgrade his skill, but Lyrventh didn't have a skill and his level was still at the very bottom, so it was impossible to do it no matter what.

So, he would just take care of him for the time being and see what kind of position suited him.

It took them three days before they could find something.

Theo still carried them in the air while scanning the city with his Awareness and Magic Power. Lyrventh was listening to every sound in the area while Lydia remained quiet so as to not disturb them.

The situation changed when Lyrventh heard something.

"This.." Lyrventh suddenly frowned. "Can you stop for a moment?"

Theo glanced back before stopping. He let them levitate in the air so that they could see their surroundings.

"Is there something wrong?"

historical

"I'm not very sure, but I feel like I can hear a vibration coming from that direction." Lyrventh pointed at the west.

There should be no vibration left since the machine had stopped after the town didn't have any more electricity. So, it was quite surprising to know there was something like this.

There were only two possibilities for this vibration. One was a monster that was trying to lure them away. Still, they hadn't even met yet and there was no way a monster would continuously do it after finding no prey for a long time.

That meant it was the second possibility. It was the clue Theo was searching for.

"I'm going to check that area. I'm going to drop you in one of the buildings and you have to hide there for a while. I'll try to go back as soon as possible, but if something happens to me, you two should try to survive for as long as you can. I'll definitely come back."

Theo landed on top of a building. Before he left, Lydia grabbed his hand, looking at Theo worriedly.

She was thankful for everything Theo had done. The last few days were truly the happiest days, so she didn't want to leave Theo's side.

But at the same time, she was sensible enough that it wasn't her place to stop him.

Theo smiled and patted her head. He kneeled down so that he could look into her eyes from the same level. "Listen to me, Lydia. You have to protect your little brother, Okay? You two have been relying on each other this whole time, so I believe you can wait for me, right?"

"Mhm.." Lydia nodded with a sad expression.

"Don't worry. I'm going to clean up the entire area first before checking the vibration. I'll be back."

Although reluctant, Lydia released Theo's hand.

After looking at them for one last time, Theo turned around and jumped into the air. But before he left, Lyrventh's voice echoed in his ears.

"Be careful."

Theo was surprised to the point he stopped for a moment just to look at him. It was quite surprising to see Lyrventh, who had been suspicious of him, say those words.

Theo waved his hand while flying away. "I'll be back."
