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 year. (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
3.New Legacy Rule: [Template]:
Concept: [Template] allows the MC to temporarily mimic the fighting style and physical abilities of a legendary warrior (remaining logical).
[Template] Acquisition Cost:
First Template: 1000 Life Essence Second Template: 10,000 Life Essence (10x increase) Third Template: 100,000 Life Essence, and so on.
Activation: [Templates] are not permanently active. To use them, the MC must utilize a new resource: "Fury Essence."
-NEW SYSTEM: FURY SYSTEM
New Resource Point: Fury Essence (Death Essence)
How to Obtain: Unlike Life Essence, "Fury Essence" can only be acquired by killing opponents in combat.
Purpose: The sole purpose of "Fury Essence" is to activate acquired [Templates].
2. Template Activation Mechanism:
Activation Cost: It requires 1000 Fury Essence to activate one [Template] that is owned. Duration: This activation will last for 30 minutes.
Effect: While a [Template] is active, the MC will gain physical enhancements and combat expertise (strength still within human limits), corresponding to the style of the legendary warrior who serves as its "template" (e.g., [Template: Achilles] will grant him strength and dueling skills).
NEW STATUS DISPLAY AT THE END OF CHAPTERS
The status display will be updated to:
{Name: Tiberius Acilius Ulixes}
{Life Essence: [Amount]}
{Fury Essence: [Amount]}
{Active Legacy: [List of Talents/Knowledge]}
{Stored Templates: [List of owned Templates]}
"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."
