Yu’er is the first NPC that you come across in Phantom Blade Zero, as you are just beginning your journey, and getting your bearings in Weeping Creek Valley – the first area of the game. What starts as a simple fetch quest, though, develops into a multi-region quest line where you also start getting involved and interested to see how it all ends for her, and her father.
It also helps that there is a trophy linked to completing the questline, and that you get a pretty interesting Medicine on successfully finishing her quests. These quests also serve as good incentive to go into unexplored areas of the map and discover other side quests or upgrade materials.
Here is how to start, progress and finish all quests for Yu’er in Phantom Blade Zero. Needless to say, there are spoilers to how this ends for Yu’er and her father.
Step 1: Beginning the Flesh Lily quest

You first come across Yu’er as you are making your way across Weeping Creek Valley, and take a rope to slide down. She is bang on the main path, and is unmissable. She tells you that she has escaped Pangzhen, with her father left behind.
She has found a recipe, and stops at that. During the interaction, select ‘How to save her Father’ and she will then tell you about a Flesh Lily as a key ingredient for a recipe. requesting you to get one – as basic a fetch quest as you can think of. This starts the Flesh Lily side quest.
Step 2: Completing the Apprentice Healer side quest at the Outpost

The next area where you meet Yu’er is at the Outpost – your hub area equivalent for Weeping Creek Valley. She has heard of the plight of other soldiers, and wants to help by giving them medicine – but, that requires a few key ingredients from areas that are too dangerous for her to go to, and that’s where you come in the picture.
This quest has you collecting 3 ingredients from 3 different portions of the map. We have put up the detailed guide here on how to go about doing that, and completing the Apprentice Healer side quest.

Completing the quest, and returning to her with all the ingredients gets you the Medicine case accessory. This increases healing effectiveness by 20%, and is a pretty good accessory to work with in the early game period. Later on, you can also upgrade Medicines to further increase its effectiveness.
Step 3: Getting the Flesh Lily
This step can technically be completed anytime after getting the quest – but the boss you have to fight to get the Flesh Lily takes some doing – and hence it is best to come to this later when you are leveled up and more familiar with the combat mechanics in Phantom Blade Zero.
To reach to this boss, start from the Valley Sha-Chi First Floor bell, and go to your left, behind the factory. There will be a hole in the wall that you can jump down to.

Defeat the enemies here, and make your way up to face Hua. You will get the Flesh Lily on defeating her. Hand over the Flesh Lily to Yu’er, and you are done with this quest for now – the next stage on this happens much later.
Step 4 – Completing A Healer’s Mercy quest

The next interaction that you have with Yu’er will be at the Thieves’ Camp – the hub area for Crimson Forest. Speak to her, and she will request you to hand out life-saving pills that she has prepared to friends of the Silver-Tongued Thief who is now accompanying her.
Like the earlier one – this also has you exploring different parts of the map (including the one where you get a key to for the Thieves’ Camp locked door).
We have put up detailed guides on the locations for all 4 to complete A Healer’s Mercy quest here. On giving the pill to all 4 NPCs, return to Yu’er, and you will get the Calming Gourd Accessory. When equipped, you can use this Medicine to recover from guard break, and prevent Sha-Chi consumption for 3 seconds.
Step 5: Interacting with Old Man Gen to update Flesh Lily Quest

The next step happens when you make your way to the Village of Lu. As you begin this region, early on, you will come across this NPC – he will be actively shouting for help on the main path, so is very difficult to miss. He updates us that a girl made her way through here recently, rushing to Pangzhen to save her father. This, updates the Flesh Lily quest – cancelling out our objective of helping Yu’er and escorting her to Pangzhen, without anything else for us to do here, for now.
Step 6: Yu’ers’ Fate in the Game

When you finally enter Pangzhen, and progress through the South Gate Bridge bell, you will come up against Blaze – and the cutscene before this, shows Yu’er – killed by him. As you extract vengeance and eviscerate Blaze, at the end of the boss fight, another cutscene ensues, where the Herald ascends Yu’ers’ body, saying that he is claiming this vessel. and mocks you for failing to protect her.

There is a Crimson Flesh Lily – but of a different colour lying on the ground. Pick it up, and the main quest updates. So does the Flesh Lily one – asking us to go check on her father.
Step 7: Meeting her father
The route to Yu’er’s place is tied to the main quest, so you will eventually make your way there as you progress through the story. There will be an Ancient Shrine Square bell, followed by a boss fight against Chang Hong, which will then unlock the way to Yu’er’s House bell.

Once the main story cutscene plays out, Soul will use the White Flesh Lily, and this successfully awakens her father. He will ask you if Yu’er is alive – feel free to choose either option – it does not have a role in how the quest ends.

In the end, her father will hand over a pendant belonging to Yu’er’s mother to you. This completes the side quest, and the trophy for this will unlock. The pendant is the Blessed Jade Pendant accessory, which, on using Medicine, does a random roll to give you one of 4 effects – two debuffs on you and the enemy, 1 an enemy AoE damage, and 1 a buff for you.
This ends the Flesh Lily quest, and all quests for Yu’er in Phantom Blade Zero.
