The Duke's Youngest Son is a Regressor

Fake system: Check! good looks: Check! face slapping: Check! brains: Check! No-harem: Check! *** My name is Cassius Blackwood, I am the illegitimate son born between Lucas Blackwood, the greatest swordsman in the empire, and Aurora Nightingale, the master of the Magic Tower. The one people expected to be a 1-in-a-million genius. So, everyone treated me kindly despite being an illegitimate child. That is, until my 10th birthday when I undertook my awakening ceremony and nothing happened. After that, everyone treated me like dirt. My parents, who had high hopes for me, abandoned me. I trained hard for 10 years and managed to awaken as an F-rank, but even then I had no system to help me. I was a "systemless hunter" And in this world, how good of a system you have is what determines your success. right after awakening, I had to undertake 'The Trial', a test to see who would become the next head of House Blackwood. all Blackwoods, including me, had to participate. To nobody's surprise, I was the first to die. So why am I now back to when I was 10 years old right before my awakening ceremony? *** Tags: #transmigration (the MC isn't the transmigrator) #regression ( the MC is obviously the regressor) #reincarnation #no-harem #romance #singlefemalelead #revenge #evil #cruel #mage #swordsman #returnee #fantasy-empire #dungeons #system( Fake system) #cultivation (done differently) #rarebloodline #action #fantasy #secretidentity join my discord: https://dsc.gg/lotuspen
