How about these new system rules? If they're suitable, I'll revise the plot slightly to fit the story and incorporate other characters who haven't joined the fanfic yet for essence purposes.
You can provide suggestions for reductions or additions.
-LEGACY SYSTEM
1.Partner Restriction: The MC can only gain "Life Essence" from the same woman once per Month. (To fill this gap, I will introduce new canon nobles into the fanfic.)
2.Legacy Cost Rules ([Talent] & [Knowledge]):
Progressive Cost Increase: The cost to unlock new [Talent] Legacy will increase by 100 Essence with each purchase.
[Knowledge] Cost by Tier:
Tier 1: 100 Essence Tier 2: 500 Essence Tier 3: 1000 Essence
"I have already seen the key points of Arc 2, and it's expected to conclude with Spartacus S3. This arc will end in a few days. I've watched the movies and TV series about Rome previously recommended by readers. So, to better plan Arc 3, I hope for input and suggestions from fellow readers. You can recommend movies or TV series that we can adapt or borrow storylines from to make this fanfic more vibrant and its future direction better. I plan to acquire all of Crassus's power when he dies later; this is the quickest path."
