Not so Jobless Reincarnation

Core Setting: The story takes place in the world of Mushoku Tensei. The protagonist resides in the Velwolf Manor located inside Oakhaven, a bustling border city situated exactly a day's ride north of Buena Village.The Protagonist: Jaxson "Jax" Velwolf is an otherworldly reincarnate born with his adult memories fully intact. He is exactly the same age as Rudeus Greyrat; during the cosmic rift of the reincarnation incident, Jax's soul was violently grabbed alongside Rudeus's soul, anchoring them into the timeline simultaneously. Unbeknownst to Jax at birth, his unique genetic makeup is a flawless six-race Convergence (Demon muscle density, Dragon mana density, Beast kinetic reflexes), paired with a hyper-concentrated Laplace Factor that grants him unfathomable magic potential and an infant body naturally adept at automatically compressing Battle Aura (Touki). He is the second born son of Lord Reinhardt Velwolf and half-brother to the first-born son.Narrative Goal for Chapter 1: This chapter must fully cover the chronological timeline from Jaxson's birth up to age 3. For the first year, Jaxson believes he is in a generic, run-of-the-mill fantasy setting, exploring his massive physical potential as a smug, overpowered infant. Right around his first birthday, he accidentally overhears a visiting knight mention the name of a local swordsman named "Paul Greyrat" down in Buena Village, triggering an immediate, intense realization of exactly where he has been reborn. The remaining two years must detail his intense, silent toddler training, his mastery of early chantless magic and Touki, and his interactions with his father Reinhardt and his older half-brother within the Oakhaven manor. Written in an epic, dark fantasy light novel style with rich descriptive prose
