Adamus_Auguste

"In order to survive the future great war, we must take drastic measures. We need to summon warriors and train them before time runs out." 

Thus, millions of earthlings were reincarnated in an alien, medieval world governed by swords and magic to save its prophesied doom.

Among those individuals, one's situation inexplicably deviated from the others. 
Thrust into a rotting house in a ghostly body, Adam found himself bound to a wailing baby. With a heavily damaged soul and the snarky remarks of a system, he began his years-long quest to recover his body. 

Armed with his mind, he'll educate the baby and slowly watch him turn into a good youth. However, he would have to make a choice: suffer as a ghost until he finds an alternative that might not exist, or possess his body and reincarnate.

He was far from imagining how dangerous this world full of possibilities could be, prompting him to question everything he knew... Including himself and this world's intentionally blurred history.

I Refused To Be Reincarnated

Arun and Asha searched for Louise and Shiro, bringing them into the room.

"We didn't find much. Everything is centuries old and rotten." Louise revealed their exploration results, shaking her head in disappointment.

"We found a mysterious book, but it disappeared after Julius took a nap," Arun said truthfully, not realising he was exposing the duo's secrets.

"..." Asha and Julius gazed at him reproachfully while Adam shrugged dismissively. They already knew too much, anyway.

Using his mana, he wrote, conversing with Shiro directly. "Do you know how to operate magic circles? Does this one have enough power to carry everyone?"

"Mhh. let me check." She answered, approaching the circle without triggering the barrier. As if as soon as Adam took hold of the grimoire, the defensive mechanism ceased its functions.
