God Messed up so I got Reincarnated

Reunion

Port Sagaru is prosperous and also beautiful. The crystal-clear ocean waters are a must visit along with its exclusive fish cuisines. Buildings are made out of shining marble from a nearby gemstone mine where the whole city glistens in the sunlight. We find ships arriving from the far seas. Yui is seen standing on one of these with Nagi next to her. 

"We're not too far from Sagaru Yui. We'll be there by today's end." Nagi tells Yui.

"Good cause I'm tired of having to use healing spells on myself for this sea sickness." As the spell wares off we find Yui puking over the edge of the ship. 

She casts another spell on herself.

"I think well be within range now. Come Yui I want to show you something." Nagi makes his way to the captain's quarters.

"Huh?" Yui follows. 

They enter the ship.

As they walk, they see the villagers that came back with them exhausted from the month-long boat ride. They enter the captain's quarters. There lies a crystal on the table. 

"A Crystal?" She asks.

"It's a communication crystal. Though it only will work so far depending on the magic caster who's putting mana into it. The farther the distance the more mana that is required. Let me demonstrate but just watch I would like to surprise the person we're about to call." Nagi explains.

"Ok?" Yui nods.

Nagi places his hand towards the crystal and pours mana into it. 

"If the person you want to speak to has one of these attuned to them all you have to do is think of them."

The crystal starts to glow and pulse. Nothing happens at first but then an image appears with a voice responding. Yui is in shock.

"These must work like cell phones from my original world!" She thinks to herself.

"N-Nagi? I thought you couldn't reach me from the continent with this after you haven't called for a while." The familiar voice says.

Yui is trying to recognize the person from the crystal but can't.

"Yea I couldn't with this one. I'm actually at port Sagaru right now since we didn't think we would make the winter there. Before I go back, I will grab a better one. Though how many mages that can rebuild a city you think you can spare including you?"

"H-huh rebuild a city what do you mean?" The voice asks.

"We'll we've made two discoveries while we we're there. One which was an old city that we could actually repair rather than build one. Thats why I'm asking for mages."

"Ohhh!, That shouldn't be a problem then if it's that. I think it'll be a great opportunity for younger mages to geta rest from battle including me. What's the other discovery?"

Nagi waves for Yui to come closer.

Yui steps closer next to Nagi. She can see the person from the crystal much clearer now.

"We found this lady right here."

Yui and the lady in the crystal stare at one another for a moment......

"YUI?!" She screams.

"SHUNA!?" Yui screams back

They both jump up and down with excitement.

"You're alive! Where the HELL you've been for the last six years!?"

"Alone on the land Nagi came to discover. Though I guess I explored it first." She laughs.
