After eating Xin and Grayfia start planning for the future, after all, Xin will eventually leave.
The first problem that the House of Lucifuge need to faces is the lack of funds, because of the war the House of Lucifuge used all their money to fund the war. After all, war is a money-eating machine if they want to win a war they need to fund it.
But unfortunately, the Four Great Mao died, leaving all their household poor and penniless, some clan is much fortunate that they preserve some of their descendants.
But for House of Lucifuge, everyone dies except for a single widow and young devil.
For the first problem, Xin came up with an idea to let Melan do a treasured hunt on the battlefield, after all even trash can still be recycled.
Xin let Melan gathered all kinds of metal that she can find on the war field, from a broken sword to a last piece of silver, anything that can be recycled.
He passes new magic back to her and casts some spell for protection, and last is he cast an improved version of Invisibility to stealthily, a combination of presence removal and invisibility.
After Melan go out, the next problem of them is protection. Grayfia know that after she comes back, lots of Pure-Blooded Devils will try to use them as a scapegoat for this war.
The Four Great Mao dies and there should be one to carry this burthen after all lot of devil die from Four Great Clan, for sure that Grayfia will going to become the living target of them, she is the one of the most powerful frontline from war and they know that in future she will become a Great Mao so it much better to take down another competitor.
And the solution for this is to make Grayfia become strong. Strong enough to fend off all the devils that want to hurt her.
Xin said," If I'm not wrong, you're a good magician right?"
Grayfia nodded," I'm a Master Magician level, and I'm good in using void and space type attack"
Xin smiled and said," Your strong, I can't even use that kind of attack"
Xin browsed the System Storage to find a good magic book for her. After a few minutes he bought three types of books.
Void Magic Book
Space Magic Book
Time Magic Book
All this book is a fundamental technique in training this kind of magic, but not only that. This book also contains different types of skills that are not easy to master.
Xin gave it to her and said," You need to hide this properly, don't let anyone take this from you. And time to time you need to study this"
Grayfia took the three-book, she thought that it was only a normal magic book but after seeing the content she was shocked.
This book is a treasure type grimoire that contains detailed techniques and skills on how to use this difficult magic.
Xin said," If I'm not wrong, there's a Space-Time Manipulation Technique there, try to master it first before anything"
"Using that magic can fasten you training to other books"
Grayfia nodded, she knows that mastering Space-Time Manipulation magic is hard, but if you master it all other techniques can easily master in a small amount of time.
The next problem for her is protection, Xin cant protect her and her mother, after all, he will leave this timeline eventually.
And Grayfia cant master Space-Time Manipulation that fast, so Xin needs to find a solution on how to protect them while she is still in mastering the books.
Grayfia said," Protecting my mother and myself is easy, but the House of Lucifuge territory is hard.
"I can only let others take the territory of my family after all that is just a simple property"
Xin said," Then where are you and your mother going to stay?"
Grayfia said," We can both stay into the old mansion of our family, after all, there are Concealment and Magic Protection in that mansion"
Xin said," I will just make Grand Protection Magic for you, but I don't know how many years my magic can last"
"But I think before my magic is gone, you already master one of the books"
Grayfia hearing Xin's plan, she accepts his idea. Just a Grand Protection Magic can already cover almost 10 km of the territory of House of Lucifuge while the effect can withstand an all-out attack of Mao.
Just from the effect, Grayfia knowsthat she and her mom will be safe for any harm.
Xin stare at her and said," Lastly I want you to leave the Old Satan Faction and join Anti-Satan Faction"
Grayfia was confused," Why?"
Xin said," The Late Four Mai already die so staying to a faction without any leader is just waste of time"
"It is much better to join the other than staying there right? And after all Anti-Satan Faction is not that bad"
Grayfia said," But-"
Before she started to speak, Xin intercept her and said," You already know the reason right? Just like what I said. Late Satan die with god but not victorious"
"They defeat an opponent that in the weak state resulting from their death, and not only that"
"They kill the biggest benefactor of the 4 realms, just for this reason. Staying in the headless faction is stupidity"
Grayfia sigh and nodded," Okay, as you wish"
Grayfia is not an idiot, the thing that the Late Mao is not heroism but idiocy. They wage a war to their greatest benefactor just like that.
Xin walk closer to Grayfia and patted her head, he smiled and said," Onee-Sama is smart so you know that I'm doing this for your own safety"
For some reason Grayfia cant reject Xin to this kind of small intimate, she feels that this kid is not her clan leader and fiance but her little brother.
After that Grayfia starts reading the books, while Xin is making a magic scroll for her protection.
Meanwhile, Melan who already flipped the whole battlefield already acc.u.mulated a a large amount of scrap.
