As they went furthur into the forest, they spot a lot monster who was coming toward them, but before they could even touch a single hair of the archduchess stella use her sword and slice the monster into pieces.
'I know from the report that i got from philif she is strong, but to this extend,' though the archduchess who suprised by stella power, she wonder if this really the same girl she use to tease everytime she come to their estate.
If her progress is this fast, she will without a doubt, surpass the lancer in no time.
After a few hour they decide to rest since it was night, though stella herself can protect herself but she can't take a risk since she was with someone.
So in a flash stella quikcly make a tend for the archduchess to sleep with the help of the archduchess who suprisingly know how to make a tend.
"I make dinner, what do you want to have, ?" Ask stella to her in law, as she brought a few cooking equipment though not as good cooking it in the real kitchen, but it will still do the trick.
"Make me a suprise," say the archduchess as stella begin to cook their meal while the archduchess herself only look toward the beautiful sky which decorated by the star, after a while, stella give the archduchess her meal as they enjoy their time while having what they girl night out in the wild.
After a quick breakfast in the morning, stella and the archduchess continue their travel to find a new mine, though they having a hard time to find something like that, since they need to find a mine that was full resourses that can be exploited for over a few generations.
3 days later, stella and the archduchess continue their travel inside the forest, as they meet with a lot of monster who stella easily kill before continue their search for the mine.
They continue their walk for a few hour until they spot some big cave entrance that caught their attention.
"wow, is a big cave," say stella who look at the cave infront of her, as well looking of what inside the cave with her eye.
"yes it is," say the archduchess who look at the entrance of cave, and saw a shiny thing on the inside.
'is that,' though the archduchess who was walking toward the entrance but was held by stella.
"stella, ?" say the archduchess who look st the brown fox girl who was holding her hand.
"i take the lead, i got a better eyesight than you," say stella as the archduchess nod her head while stella walk infront.
as they walk they stumble upon something that caught their eye.
"this is a magic stone right, ?" say stella as she giving it to the archduchess.
"yes it is, but i never though that there a lot of this thing in here," say the archduchess who look around and found a lot of magic stone in this cave, even in the mine that was owned by the the dwarf itself has nowhere this much of magic stone.
'it could even be more in the bottom floor, but we need to make sure of it,' though the archduchess to stella who nod since she know what the archduchess want as they continue to explore the cave even furthur.
as they went even furthur they found a lot of tunnel that lead other place that contain a lot of gem and mineral, but they ignore all of that since they need to explore all of the tunnel in this cave to make the decision.
'we been walking for an hour, just how long this tunnel is, i bet that even the archduchess is also tired,' though stella as they continue to walk for a few minute until they saw a different room infront, as they walk in their eye widen of what they actually saw.
after that stella and archduchess decide to go back on the surface while they had a lot of mind of what are they gonna do for now.
"stella, i think is best if we keep this place a secret for a while, this teritory is under archduke vincent property so there won't be any people who stumble this place by coincidence, if that person is not have the archduke permission," say the archduchess who look at the entrance of the cave that was really big.
"But in case if someone found it by accident, we need to make sure that will never happen," say the archduchess as she look at stella who just nod her head as she activate her magic and make a gigantic wall made of stone to cover the cave entrance.
"and the finishing touch," say stella as she pull her sword and swing to the wall before she make it the wall and destroy it once again, to make the cave was block by a narutal disaster of something like that.
"alright, now let's go home," say stella to the archduchess who smile as they go back to naval kingdom.
after stella accompany the archduchess safely to her home, stella went straight to the duke estate where she silently went to her room, and to her suprise, her little sister was sleeping in her bed with a blanket on it.
'look like i need to thank the head maid for taking care of her,' though stella who at that time change her clothes as she sleep beside her sister.
in the morning, stella decide to take a break from all the adventure and training that she do, and spend more time with her little adopted sister who was playing with her tail.
"stella, are you in here, ?" ask someone in the door.
'the heas butler huh, what is it now,' though stella as she open the door who reveal the head butler.
"the duke ask me to inform you to come to his office," say the head butler as he leave after infrom stella.
"alright, why don't we go together eve," say stella as she happily let herself got hug by her older sister as stella quickly walk toward the duke office where the duke was in the room along with the other 3 knight in there.
"i'm sorry that i late," say stella to the duke who just nod before stella line up with the other knight whike facong the duke with hed litlle siter on her arm.
"in a few days the royal family will held a party for their son birthday, i want you guys to take part of the party as a bodyguard," say the duke as the head butler come and give them a bag of suitcast for each of them, except sfella who was given a dress.
"alright that all, you guys can go," say the duke as they leave the duke office, and do their usual activities.
