Mushoku Tensei - A Second Chance

***SPOILERS for Mushoku Tensei anime watchers*** This fan-fic will contain heavy spoilers for any anime-only fan of Mushoku Tensei. You have been warned. This story considers what may have happened if the Rudeus from the future had been successful in his attempt at time travel. What if Rudeus' attempt at time travel had resulted in him traveling back into the body of his younger self? After researching time travel with the help of Perugius and Nanahoshi, Rudeus makes his attempt only to find himself opening his eyes to see Paul and Zenith doting over their newborn son. Rudeus is essentially given a second chance at life in this world starting with all the knowledge he had accrued. Will he be able to protect his family this time around? Please note this is my first attempt at writing of any sort. I would honestly appreciate any critiques and advice. I don't mind criticism, but please be kind about it.
