Arknights Hengyuan Jinliang Crossover Guide: Lvgu Build and Vector Break #3 Wrap-up
this guide puts the three October jobs in order. Hengyuan Jinliang is a login sign-in that costs no sanity at all. Lvgu, the free 5-star Specialist Alchemist from the Yesterdays' Sea SideStory, is a control unit rather than a damage dealer. And Vector Break #3 needs its milestone finished before 19 October. Every date below is checked against official announcements; a fuller version lives on GameHub's mobile game guides hub.
Applicable version: as of the 2026-10-09 update (Arknights has no version numbering; the official announcement date is the time anchor)
Arknights Hengyuan Jinliang crossover overview: a zero-sanity login event
Hengyuan Jinliang extends the Arknights collaboration with the National Library of China, and the official framing is a login sign-in event that costs no sanity at any point.
What the crossover actually gives you
The cumulative sign-in rewards are limited furniture; the Hengyuan Jinliang collaboration skins and avatars go on sale separately and must be bought . That is the real difference from a SideStory, which ships a token shop and a free operator. A crossover ships a sign-in and a shop, nothing more.
Why it goes before Yesterdays' Sea
A sign-in event takes no sanity, so one login a day moves it forward, and a missed day is simply lost progress . It sits first only because it costs nothing and needs no farming plan built around it.
Arknights Lvgu build: the 5-star Specialist Alchemist
Lvgu is the free operator from the Yesterdays' Sea SideStory, a 5-star Specialist in the Alchemist subclass whose kit leans on control and debuffing.
Is the first talent worth investing in
Lvgu's first talent lowers the physical and arts accuracy of ground enemies inside the range of her alchemy unit, while both skills slow ground enemies and deal arts damage per second . That makes Arknights Lvgu build planning simple: she is not a carry, she is the unit that stretches enemies across your timeline.
Skill 1 versus Skill 2
Both skills slow and tick arts damage, so the choice comes down to coverage. My call is Skill 2 when you need a lane held for a long stretch, Skill 1 when you need a short interrupt window. The reason I would not rush a Mastery 3 is that her value swings with enemy placement, which makes her a situational pick rather than a default.
E2 order and materials
Plan Elite 2 around the standard 5-star material tier and stop once she can actually reach the field; there is no reason to empty your stockpile for a Mastery 3 .
Arknights October sanity plan: three events, one calendar
Yesterdays' Sea, the Hengyuan Jinliang sign-in and the Vector Break #3 wrap-up all overlap. At 240 sanity a day across a 21-day window you are looking at roughly 5,040 sanity for October .
| Window | Main job | Where sanity goes | Priority |
|---|---|---|---|
| Oct 11 to Oct 15 | Yesterdays' Sea part one | First-clear plus shop exclusives | High |
| Oct 16 to Oct 19 | Yesterdays' Sea part two and the crossover sign-in | Token re-farming plus daily login | High |
| Oct 20 to Oct 23 | Vector Break #3 wrap-up | Milestone catch-up | Medium |
| Oct 24 to Oct 30 | Yesterdays' Sea finale | Clear out tokens | Medium |
The Vector Break #3 closing window
The stages close on 20 October at 03:59 and tokens stop dropping; the milestone claim window runs three days longer, to 23 October at 03:59 . Practically, you want your score banked by the evening of 19 October.
Should you keep farming Yesterdays' Sea tokens
Yes, but only after the exclusives. The shop order is operator tokens, limited furniture, module materials, then standard materials, with LMD dead last . The most common mistake I see is players cashing tokens into LMD early and only noticing at the end that the limited furniture never got bought.
Arknights Vector Break #3 "Niche Ecology" wrap-up
Vector Break #3 opened on 29 September at 16:00 and closes on 20 October at 03:59.
Milestone tiers
The milestone track hands out progression materials and limited tier rewards unlocked by cumulative score. Check how far you are from the next tier, then decide whether buying sanity is worth it.
What you lose if you skip it
Skipping only costs you this event's milestone rewards; tokens do not carry over and never convert. The damage is contained, which is exactly why it sits behind actual content in priority.
Arknights crossover skins and furniture: should you buy
Furniture comes free from sign-in, skins cost money, and those are two separate decisions.
Free-to-play trade-offs
If you only want the free slice, sign-in already covers the furniture . Limited furniture is a permanent display item with a stable payoff.
What paying players are getting
Crossover skins are sold as a series, and whether to buy is a taste call; the official line is that they do not affect combat power . Treat them as optional, not mandatory. Full archive lives at gghubs.com guides.
