"How could this happen?"
After his death, the moment he open his eyes, he's back at his village. He looked around to confirm if this is really his old village. After confirming that it is his village, he looked at his hand, his small childlike hand. Looks like he's back to the time when he's just reincarnated in this world, but when?
He rushed to his home. Even though it's been years since he visit, he still remember the way home.
Bursting through the door, out of breath and have an expression as if he was chased by a wolf, he found his sister with a basket in hand, he asked.
"How old am I?"
His sister give him a weird look, for obvious reason.
"Um... 9? If you're excited about your 10th birthday it's still a month away... Did something happen?"
She put down the basket and went to check on him, wondering if something bad happen.
"It's... Nothing"
"Well you looked like you got chased by someone... You're not stealing something from the neighborhood right?"
"What? No! I would never do that!"
"I see... Then what happen?"
Obviously, he can't just say that he's reincarnated again, so he catches his breath, looks around and gives a tired sight.
He then convinced his sister that he's not stealing shit from the neighborhood... Or trippin on some weird mushroom he might found in the woods.
He then decided to walk around the village to enjoy it. This is because once he turned 15, he will be joining the military since he got the body for it, and also because it's a honourable job for someone like him. It's also a not so dangerous job since the age of war has ended hundreds of years ago. All he had to do back then was guarding a carriage with his squad, dealing with bandits, patroling the capital and so on. It's really just a stupidly bad luck that a demon war happen while he's still serving and attacked by a demon in a relatively safe town.
Even with that in mind, he still decided to become a soldier. He got no choice since the condition on him being an adventurer is being able to use magic, which he got no idea how at the early age. Guess he will just get stronger to at least survive, or quit and become an adventurer before it happen, or even become strong enough to convince his parents and let him become an adventurer once he's 15.
There's no need to deal with monster and such for the military since the adventurers guild got that coverd. His parents doesn't want him to be an adventurer, and in truth, even he doesn't want to. Dealing with monster, something he never do, is kinda scary. There's other job not involving monster subjection for adventurer but it didn't pay as well as killing monsters. At least that's what he thought back then, now tho he probably could handle the low class monster.
He's still kinda surprised how he got big, who knew this tiny body will grow so tall. How tall? 172 cm when he was 15. When he was an adult, he grew even more, 182 cm. That doesn't effect his rank tho.
For this reason, he decided on getting ready for it. Back then, he learnd everything so late to the point he is stuck to just being a foot soldiers even tho he can use mana.
He then stop at a big tree near a river, where most of the villagers went to take waters. This way, his sister wont get made at him for going too far in the woods. He wasn't far from home, it's close but the walk is far from a short walk.
"Alright, how should i do this"
He recollect on his past life training to find what he should be focusing on. After sometime, he decided to work on his mana core, and get some endurance training in after that.
"Let's start with mana coating"
Mana coating is the basics of mana manipulation. Basically, just controling the mana from leaking out of his body. This, will result in mana shrouding his entire body.
He sits, silence himself and his thoughts, and focus to the sound of the river. And then...
Nothing... Obviously it isn't something he can achieve in his first day. Even with the memory of how he's doing it, his body doesn't remember it so it need to get used to it first.
He sits there with his eyes closed, like a monk trying to find enlightenment, for an hour. He couldn't muster his focus anymore and getting distracted by thought. So he got up, and started running to begin his endurance training. There isn't much he could do with this body so that's the best choice to avoid injuries.
He does this again and again, changing between them after getting tired of one of them, until the sky is turning a bit red.
"I guess that's it"
Out of energy, he head back home before it's dark, or he will get scolded for it. Something about this feel nostalgic for him.
Back in the military training, he missed his family from both world, his first life family and this life family, to the point he will let a little cry at night.
He's used to it now, but nothing is wrong from spoiling himself with family love, even tho he's a full grown adult on the inside. Or older than that.
