When I wake up in my third day on this another world I went to the first floor to eat my breakfast and when I finished eating I went to the the Towns library to research some magic spells to learn I went to the third floor of the library and I finally see the magic spells section I went to that section to look some magic book to learn a magic spells when I get the magic book I borrowed the book to learn some magic.i went to the abandoned ruins to practice some magic "hmm let's see ice barrier huh it's creates a ice barrier to defend it's seems useful for incoming attacks like arrows I guess" i said. when I looked all the pages in the magic book I see some interesting magic that I found "regeneration magic it can regenerate the people who got loses some limbs huh let's try it" i said. I cast wind blade to cut my left arm and "ahhhh it hurts so much" I said with a loud pain voice.and I cast the regeneration magic into my left arm "regeneration" I said. and when I looked my cut left arm its rapidly regenerate and my left arm are back to normal it's a success and I continue searching some useful magic that I can use for battling some monsters and I want to practice some defensive magic spell to assist Sylvi if something happens to her so that I can support her when I keep looking some useful magic spells and there's something caught my eyes on the magic book and I see some magic buff spell and it's very useful for support Sylvi in battle that I can give her a buff for boosting her when she is fighting a monsters "yup it's very useful for fighting a monsters" I said.and I read all the magic buff spell "berserk magic buff it's said huh it's said when a caster target to an allies it will buff the target with berserk it will raise all physical attack and movements" it's said huh it's useful for Sylvi anyway she's a sword fighter anyway so it's very useful to her when I read all the magic spell it's began to sunset "it's sunset already" I said. when I read all the magic spell I went to the Library to to give the magic book that I borrowed and wen it's done I went to the inn and I remember "where's Sylvi" I said to the owner of the inn. "Sylvi you say she went to her room to take some rest" he said. so I went to my room to take some rest and ask Sylvi to take some mission to adventurer guild to try my magic spells on the monster and I went to sleep for the upcoming day.
