I remember reading an isekai novel a year or two ago, I think it was here, but im not certain.
It started off with the kid being born, his mother gathered extremely poisonous roses with thick leather gloves for a living,like most of the village. I don't remember what happened, but the mother killed the father. She was also planning a murder suicide with the MC, who was still a toddler. So he carefully took a thorn from one of the roses and embedded it into a tool he knew his mother would grip, get pricked,and die. After that, I don't remember too well what happened, but he got close to a noble house as a servant or something, and tried training with the guards. Afterwards, some time passed,and he went to war, I don't remember why. He was still VERY young, but his accomplishments got him ranked relatively high. He had his own unit. Last I remember, he and/or his unit got cornered by ghouls or something in a giant hollow tree or stump. I read this about a year or two ago, so any one of these sections I think I can remember from this novel might be mixed in from others, so if any one of those scenarios rings a bell,but not the others, let me know anyways. Thanks in advance!
