Fertility overhaul for House of Legacy (吾今有世家) — make conception easy, instant, and fully under your control.
Features
Fertility boost (automatic)
- Multiply the monthly pregnancy chance of your own family — wives/consorts, female clan members, and your people in the royal palace (default x10, configurable 1–100).
- Optional Family: always pregnant switch — every eligible spouse conceives on the next month tick.
- Separate multiplier for other clans, if you want the whole world breeding faster.
Affairs always succeed
- With Affairs: always pregnant ON (default), every affair / secret-liaison event in the game guarantees conception — including women of other clans you meet through outings and events. Father attribution works exactly like vanilla, because the mod routes through the game's own affair-conception code.
Bloodline secrets — the cuckoo ledger (NEW in 1.1.0)
- Every affair conception is secretly recorded: mother, her clan, the real father (when the game tracks him), the event that caused it, and the in-game date.
- When she gives birth, the ledger identifies the newborn - so you always know which children across rival clans (or inside your own house!) are secretly of your blood.
- Bloodline tab in the F6 menu: live pregnancy countdowns, born children by name, and a summary like "your blood runs in 3 rival clans".
- Stored per save-slot in
BepInEx/config/- never touches the game save; safe to remove.
Claim & real genetics (NEW in 1.2.0)
- Claim secret children (other clans) home from the Bloodline tab - correct generation/family tree via the game's own member factory, talents carried over, rival-clan records cleaned. Children below adult age only (v1).
- Real inheritance: when the real father is known, the newborn inherits his talent line (and sometimes skill).
- Birth notifications on screen, and a father picker in the menu header so conceptions record who the father is.
- Vietnamese/English interface (
Languageconfig, VI default).
Birth control — yours to command (NEW in 1.3.0)
- Gender select: newborns in your family are Natural / always boys / always girls / a custom % of boys (
GenderSelect,BoyPercent). Claimed children keep their real sex. - Twins & triplets: every family birth has a configurable chance of a second baby (
TwinsPercent, default 20%) and then a third (TripletsPercent, default 5%) — with an on-screen announcement. - Fast pregnancy:
PregnancyMonths(1–10) shortens every pregnancy, including ones already underway, in every pool. 10 = vanilla. - Give birth now: a button next to every pregnant woman in the F6 lists — she delivers on the next month tick through the game's normal birth flow.
- No postpartum rest (default ON): wives/consorts can conceive again immediately after childbirth.
Legacy - bloodline quality (NEW in 1.7.0)
- Eugenics: minimum talent/skill for every child born into your family, plus a talent picker driven by the game's own talent table.
- Child limit raised for your family, no jealousy, new marriages start devoted, seizing a bride costs no fame, palace tribute & consort selection always succeed, your exam candidates ace the imperial exam.
- Bloodline: descendants tracked by generation, incest warning on people who secretly carry your blood, rename claimed children, and export the whole bloodline to an HTML page.
Housing (NEW in 1.6.0)
- A Housing tab lists everyone in your family with no home, grouped by estate - with a button per person, per estate, and one for everybody.
- Works from anywhere: the estate you stand in is read live, the others read-only from their own save data.
- Only the homeless are listed, so nobody loses the home they already have. Uses the game's own residence data and headcount call.
Marital harmony & palace claims (NEW in 1.5.0)
- Marital relationship: a slider plus per-couple and bulk buttons in the My-family tab set the husband/wife relationship of your spouses (the game's own field, both directions).
- Claim from the palace: secret children born in the royal palace can now be brought home, not just children in rival clans. Royal safety locks apply to a child who has since become crown prince.
Proposal — marry anyone into your house (1.4.0, fixed in 1.6.1)
- The game's own propose button always succeeds as well (
ProposalAlwaysSucceeds) - no more "not interested". - A Proposal tab listing every eligible single adult: rival clans, royal kin, princes, princesses, consorts; a tick shows those who cannot be proposed to, with the reason.
- One click = the marriage always succeeds, through the game's own marriage routine. Royals are retired from the royal household the same way the game does it when a royal marries out.
- The Crown Prince is behind an explicit tick: he becomes an ordinary member of your family and loses the crown-prince title, so name a new heir afterwards.
- The Emperor is locked behind
AllowEmperorin the config: his row is what court events, edicts, impeachments, appointments and succession all look up. Removing it can break those systems. Back up your save. - Nothing is ever half-done: a refused or failed proposal changes nothing.
Instant pregnancy menu — press F6
- A clickable in-game menu listing, per tab:
- My family — your wives & consorts and your female clan members
- Royal palace — your women in the palace and royal consorts
- Other clans — every rival clan's women and wives
- Click Make pregnant on anyone → pregnant immediately (10 months, vanilla countdown).
- One button to impregnate all eligible family spouses at once.
- Live sliders/toggles in the menu header — no restart needed; settings persist to the BepInEx config.
Safety
- Uses the game's own conception routine (
HuaiYun_TouQing) for everything, so pregnancies, birth events and father attribution behave 100% like vanilla. - Never double-impregnates: "already pregnant" and adult-age guards stay active.
- Pure Harmony runtime patches — no game files modified. Works with existing saves; safe to remove any time (ongoing pregnancies simply continue).

Tiếng Việt (tóm tắt)
Mod tăng khả năng thụ thai: vợ/thiếp dễ mang thai (x10, chỉnh được), sự kiện tư thông luôn đậu thai (kể cả nữ nhân gia tộc khác), và menu F6 — bấm nút là mang thai ngay lập tức. Mới 1.3.0: chọn giới tính con (trai/gái/tỉ lệ %), song thai & sinh ba theo %, rút ngắn thai kỳ (1–10 tháng, áp cả thai đang có), nút Sinh ngay cạnh từng người đang mang thai, và bỏ ở cữ — sinh xong thụ thai lại liền. Tất cả chỉnh ngay trong menu F6. Mới 1.6.0: tab Nhà ở - liệt kê mọi người chưa có nhà theo từng phủ đệ, bấm nút xếp cho từng người / cả phủ đệ / tất cả, dùng được ở bất cứ đâu không cần đứng trong phủ đệ (không ai bị dời khỏi nhà đang ở). Mới 1.5.0: chỉnh quan hệ phu thê của thê thiếp (thanh kéo + nút từng cặp + nút áp cho tất cả), và Nhận về tộc giờ dùng được cho cả con sinh ra trong hoàng cung chứ không chỉ gia tộc khác. Mới 1.4.0: tab Cầu thân - cầu thân với bất kỳ ai (gia tộc khác, hoàng thân, hoàng tử, công chúa, phi tần) là luôn thành công và kéo người đó về gia tộc bạn. Thái tử phải tick riêng (anh ta sẽ mất tư cách thái tử - nhớ lập thái tử mới). Hoàng đế bị khoá cứng, chỉ mở trong file config vì dòng dữ liệu của ông là mỏ neo của sự kiện triều đình, thánh chỉ và việc kế vị. Mới 1.2.0: giao diện tiếng Việt, thông báo khi con bí mật chào đời, chọn cha trước khi bấm nút, con thừa hưởng thiên phú từ cha ruột, và nút Nhận về tộc — đưa đứa con bí mật ở gia tộc khác về với gia đình bạn (đúng thế hệ, đúng gia phả). 1.1.0: Sổ Huyết Mạch Bí Mật — ghi lại mọi lần tư thông thụ thai, khi đứa trẻ ra đời sẽ biết chính xác đứa con nào ở gia tộc khác mang dòng máu của bạn (tab Bloodline trong menu F6). Cài qua Thunderstore Mod Manager là xong.
Compatibility
Built and verified against the Steam build of House of Legacy (2026-04 update, Mono/BepInEx 5). If a future game update renames internal methods, the mod disables itself gracefully and logs an error instead of crashing.
