"*Aish* That guy almost used my sealing array against me," Grey sighed before disabling the array.

The forest he was previously resting in was already in ruins.

"Damn it! Those morons killed my horse, do they know how much it cost me?!" He yelled in anger when he saw the bloodied horse.

From how it looked, he guessed it must have been pierced through by multiple spikes when the Water and Earth Elementalists were attacking him previously.

Whoosh!

"You're truly something," Diluc said as he appeared behind Grey.

Grey shrugged before opening up a hole on the ground and gently pushing the horse into it with his wind element.

"Such a shame you had to die because of me," He muttered after burying the horse.

"When will we be heading back?" He turned his attention to Diluc.

"I could sneak you back to the city now, but I think waiting till it gets dark isn't a bad idea," Diluc replied.

"Hmm," Grey nodded gently before heading towards one of the few trees that was still intact in the area.

'Since it's not even noon yet, I have a lot of time before it gets dark. I'll focus on comprehending the space element while I'm here.' He thought.

While he was leaving the city, he told Void to go and check out the Reiss family compound again. Since Alice's father confirmed she was still in the compound, it meant she would be under the room Void tracked the light dot to.

Void never saw the device anyway, they just assumed she left it since she wasn't there.

'Hey, have you been able to find her?' He asked Void who was currently in the Reiss villa.

'Not yet, but I should be getting to the secret passage soon, I think,' Void replied.

'Okay, don't make contact with her when you find her. After I come back to the city, I'll write a letter to her explaining what happened.' Grey ordered.

'Okay,'

After passing on what he wanted to Void, he immediately started cultivating.

Diluc glanced at him, seeing that Grey immediately started cultivating as soon as he was free, he decided to let him be.

Later that night.

"It's time, let's go," Diluc walked up to Grey and said.

Grey's closed eyes snapped open, he stood up and held onto Diluc's left hand.

Whoosh!

Diluc flew into the sky, with Grey in tow. After getting to a proper height, he shot straight for Frost City.

'So this is the speed of an Overlord Plane expert when they're flying?' Grey'l thought to himself.

He could barely see anything since they were moving too fast. When Brown took him to Red City the last time, he thought it was fast, but the griffin is no match for Diluc's current speed.

A minute later, he was able to see the outline of Frost City from a distance, but to his surprise, the city became bigger within the quarter of a second.

Frost City, Lenz villa.

"I'm afraid you're going to have to stay here, keep the communication device with you so you can contact me if you need anything," Gerald said after opening the door to a small room.

After Grey got to the villa, Gerald quietly brought him to a secret room in the villa. Each family naturally has something to hide, so must would rather build these secret rooms.

The only people who knew Grey was in the villa were Gerald and Diluc. To make it seem real, Grey told him to try and make sure only a few people knew of his presence in the city.

"It's okay, I don't plan on going out anyway," Grey stepped into the small room.

The room was barely ten meters wide, but it would do.

"Okay, contact me when you need anything," Gerald replied before turning around and leaving Grey alone.

After watching Gerald leave, Grey walked out of the room. He wouldn't only be researching on the communication device, but he would also be trying to comprehend the space element. It would be dangerous if someone were to walk in accidentally when he comprehends the element and sees him using it.

Therefore, he decided to made a detecting array on stairs that leads to the room. Once any one walks through it, then he would be instantly alerted about it.

Creak, Slam!

He closed the wooden door after he was done with the array.

"Come on out, how did it go?" He looked at the empty bed on the room.

Void suddenly appeared on the bed after hearing Grey's question.

'I found her, and she's alright.' Void replied lazily.

"Oh, that's good. I'll start writing a letter for you to take to her now," Grey brought out ink and brush, and immediately started writing a letter to Alice.

He told her the reason why the Emperor was searching for them, as well as what happened during the time they left him in the Academy.

Not only that, but he also told her about Reynolds, as well as his encounter with her father. Of course, he left out the part where her father threatened him, he also told her not to let him know he contacted her since he refused to take him to see her.

"Since I've confirmed Alice is okay, I need to get to work on the communication device."

"Hmm, now I'll need to head back to where Reynolds is located so I can give him the device when I've made it."

Grey thought out loud after Void left with the letter for Alice.

"Guess it time to get to work, I need to make this as soon as possible. Luckily, I took enough wood from that guy,"

With that, Grey brought out all the papers he had previously drawn the arrays on. He initially didn't think he would get to keep the device with him for this long.

After preparing everything, he immediately started working on the arrays. Once he gets the catch of it, he would implement it on a wooden item.

He planned to add the communication array to the same wooden disc he was using to locate the others.
