Quick answer
Picking up any one of them starts the quest Secrets at the Heart of the Lake, and collecting all six is the step that moves that quest forward toward Dusk and the four Acolyte masks.
Guide details
Reward: +10% maximum HP, permanent, when all 6 petals are collected. A partial set gives no health bonus.
Where: all 6 petals are in Village of Lu. No petal in this set sits in another region.
Quest: picking up any petal starts Secrets at the Heart of the Lake. Collecting all six moves it forward.
Order: collect in any order. The Roman numerals I to VI are story order, not pickup order.
How to spot them: look for patches of blue flowers on the ground. Each petal sits in one.
Quick answer
Start at the Old Man Gen's Hideout Bell for petal I, the Well of the Three Puppets Bell for petal II, the Covered Bridge Bell for petals III and V, the Engine Giant Remains Bell for petal IV, and the Temple of Blue Fireflies Bell for petal VI. Petal I is the one to grab first: it sits in the yard past Zhuo Bi the Gatekeeper, and picking it up starts the quest. The table below lists all six with their nearest Bell and the landmark to look for.

8. What you get for all 6 petals
1. Before you start: how the set works
Memory Flowers work as sets. A single petal gives nothing on its own: the +10% maximum HP arrives only when all six Firefly petals are collected. The petals are scattered across Village of Lu, and the village holds 16 Memory Flower pieces in total across five sets. Firefly's is the only six-petal set in the village, and the only one tied to a quest chain.
Each petal shows a memory card with a Roman numeral when you pick it up. The numeral is the chapter of Firefly's story that petal tells, so the numbers will come out of sequence as you collect them. That is normal. The walkthrough order below follows the numerals I to VI, but any order works.
Look for blue flower patches. Every petal sits in one, and the blue stands out against the village ground.
Some petals sit past fights you cannot skip: Zhuo Bi the Gatekeeper guards petal I, and the Village Auntie guards the house on the way to petal V.
Picking up any petal starts Secrets at the Heart of the Lake. The quest does not wait for a specific petal.
2. Petal I — Heart of the Lake
This is the natural first petal, and the one that starts the quest. From the Old Man Gen's Hideout Bell, go through the old house, the wooden door, and the stone courtyard. Defeat Zhuo Bi the Gatekeeper, then cross the arena to the far side and follow the small path. Pass the corpse by the roadside, with a Blackstone Shard chest behind it, and the ground turns blue. Two child puppets stand in the flower patch. Pick up the petal here and Secrets at the Heart of the Lake begins.
Bell: Old Man Gen's Hideout.
Fight: Zhuo Bi the Gatekeeper, in the courtyard past the old house.
Landmark: two child puppets standing in blue flowers, past the roadside corpse.
3. Petal II — Phantom Art Illusionists' Settlement
From the Well of the Three Puppets Bell, pass the small red shrine and follow the stone path along the cliff down the stone steps to the water. Wade into the shallow stream: the petal glows in the water beside a blue flower patch, among wooden crates near the waterfall. Watch for the Maskwalkers in the river as you cross.
Bell: Well of the Three Puppets.
Route: red shrine, cliffside stone path, stone steps down to the stream.
Landmark: blue flower patch in the water by the wooden crates near the waterfall.
4. Petal III — The Herald
From the Covered Bridge Bell, cross the grassy area with its enemies, pass between the wooden houses, and head down to the rocky main road. Where red threads cover the area, you are close. Clear the puppets around the red altar, and the petal is in the blue flower patch in front of the altar, in the shrine courtyard below the broken bridge.
Bell: Covered Bridge.
Route: grassy area, between the wooden houses, down to the rocky main road.
Landmark: red altar in the shrine courtyard below the broken bridge, puppets gathered around it.
5. Petal IV — The Source of Calamity
From the Engine Giant Remains Bell, step into the dark shrine beside the Bell. Go through the shrine room, past the purple chest, then through the dark room behind it to the doorway where daylight comes through. Follow the dirt road past the broken house and the wooden crates to the end, and the petal is in the blue flower patch under the tree there.
Bell: Engine Giant Remains.
Route: dark shrine, past the purple chest, through the dark room, out the daylight doorway, dirt road to the end.
Landmark: blue flower patch under the tree at the end of the dirt road.
6. Petal V — No Word
From the Covered Bridge Bell, cross the bridge and take the right fork uphill to the ridge. Go through the red-flower courtyard into the old wooden house, through the dark room to the gap where light comes through, then down the steps to the big tree. The petal is in the blue flower patch under the tree, at the cliff edge.
Bell: Covered Bridge.
Route: cross the bridge, right fork uphill to the ridge, red-flower courtyard, old wooden house, dark room, steps down.
Fight: the Village Auntie in the larger house across the bridge, on the way to the petal.
Landmark: big tree at the cliff edge, blue flower patch under it.
7. Petal VI — The Acolyte
From the Temple of Blue Fireflies Bell, go up the stone steps and into the candlelit dark temple. The petal floats above the rear altar, among the candles on the long carved altar table. All guides agree on this one: the temple, the candles, and the altar are the landmarks.
Bell: Temple of Blue Fireflies.
Route: stone steps up into the candlelit temple.
Landmark: rear altar, petal floating among the candles.
8. What you get for all 6 petals
Collecting the sixth petal completes Firefly's Memory Flower and raises Soul's maximum HP by 10% permanently. The bonus lands when the set is complete, not before. Three six-petal sets in the game are worth 10% each: Inanis' Memory Flower in the Crimson Forest, Yan'er's Memory Flower in Village of Lu, and Firefly's.
The set also moves Secrets at the Heart of the Lake forward. Walkthroughs note that Dusk's hidden boss arena cannot be reached until all six petals are collected. From there the quest continues through the four Acolyte bosses and their masks to the Four Guardians' Mirror on Meigu Lake, which is the path to the Perfect Ending. The Acolyte fights are covered in full in our Acolyte guide, linked below.
6 of 6 petals: +10% maximum HP, permanent.
Quest: Secrets at the Heart of the Lake moves forward; Dusk's hidden boss arena opens up.
Next step: the four Acolyte masks and the Four Guardians' Mirror, covered in our Acolyte guide.
FAQ
Do I have to collect the petals in order?
No. The Roman numerals are the story order of Firefly's memories, not the pickup order. Grab whichever petal you pass first; the set completes when you have all six.
Does one petal give any health?
No. The health bonus is paid only when the set is complete. A single petal gives the memory card and starts the quest, but no HP until all six are in.
Can I miss a petal?
No guide marks any Firefly petal missable. All six sit in Village of Lu, so if you pass one, walk back from its Bell and pick it up.
What happens after I collect all six?
Secrets at the Heart of the Lake moves on to the four Acolyte bosses. Each one drops a mask, and the four masks open the Four Guardians' Mirror on Meigu Lake. That chain is required for the Perfect Ending, and our Acolyte guide covers all four fights.
