This guide was made because its not very clear in the game on how to get started with the Black Crow / Night Crow / Assassin organization.
I'll be using "Black Crow" because I forgot it was supposed to be called "Night Crow" while making the picture for the guide.
Most of the information can also be found in Matchless Kungfu patch notes, but people don't usually go there to find things out, because of that I made this guide to help you out.

FYI Black Crow is not a sect, so you can be a part of a sect while being a part of the Black Crow too.
There are TWO WAYS of joining the Black Crow.

Get title 'Inhumane' by killing a Close Friend, Intimacy or someone from your Bloodline.
From my experience, this also includes taking the head of the person you killed.
After some time, an assassin from the Black Crow guild will interact with you and compliment you briefly before recruiting you to become one of them.

Side note: You get 10 negative stacks that reduce your spirit from doing this, to get rid of them you need to go to the City Guardian and worship the diseased
The City Guardian

After the first time the Black Crow introduce them selves, you become able to drop Blood colored cloth strip from defeating assassins sent to fight you.
Other than that there is a chance for them to appear in the Cargo Ships, so you can buy them from there too.
You can also find a bunch of them in the treasure chest of the current "one's ancestors" (explained later if interested)
Instructions on how to use it is shown in the item description.
You can check the time by holding T or looking at the moon/sun
After you use it at a high place, an assassin will meet you surprised that you know of the existence of their organization, and will ask you if you want to join.

Once you have become an assassin, you are supposed to take assassination quests which no one in the game really explains to you how to do (except the patch notes).
If someone requests an assassination on someone (visually represented by an NPC releasing a black crow), a well will get a blood cloth attached to the side of it. If there is a blood cloth attached to the well, a new option while interacting with it will show up, saying "Fishing Task", here you can see all people marked for assassination and by who they were marked (unless the person requesting the assassination is high rank in the assassin guild)
Other than fishing task there is Publish Assassination if you have a Blood Cloth, using it you can pay needed amount of Blood Coins to order an assassination on a target.

Some information on the target is given in the list, you'll have to figure out your self on how to find the target because the assassination order's do not ping the target on the map.

Accepting an assassination order gives you a status with a timer of 10 days.


Completing an assassination order gives you a status with the same icon informing you that you've completed it.


After completing the assassination you are supposed to use the Blood Cloth again to report your mission, the guy that appears will give you your reward, this is also one of the ways you can ask for promotions in the Assassin guild.

This is really all the information you need to get everything else figured out if you don't want to be spoilered to some extent.
I will still add all the other information in question like the "Mysterious Key" in the rest of the guide.

Black Crow Ridge is a map tile which serves as the main location for the Black Crow and where the "Blood List Stele" is located

Interacting with the Blood List Stele (if you are an assassin) lets you purchase rank promotions and access the assassin shop
This is the 2nd and last way to rank up in the Black Crow guild, and its the only way of accessing the shop.


The Blood List Stele is also a secret passage to the one's ancestors treasure (Fu Jun rank's treasure)
To access it you'll need a key item located in Dragon Fang Loch.

Dragon Fang Loch is a map tile that contains a chest located in an underwater cave guarded by a Black Serpent.

Once the player acquires "The key to Black Sparrow's Chamber of Secrets" or "Mysterious Key" and have it in their inventory they get another interactable option at the Blood List Stele which lets them open the secret passage.

The key changes his name depending if you are an assassin or not

Once the player has The Mysterious key and the map Black Crow Ridge, they can open the door to the secret location in Black Crow Ridge, you do not have to be an assassin to access this location.

The reason I'm calling it "One's Ancestors treasure" is because story vise, its where the current / previous assassin guild leader hid his treasure. You don't need to eliminate him to find it and take it.


There are two things that you can find inside:
-Mystery Stele
To my knowledge, it has absolutely no purpose except to look cool and menacing, it does nothing.

-Eight faced black sparrow box / Treasure
It contains a bunch of valuable loot that you can see in the picture below

I'll explain the Night killing method in the valuables section

In this section I'll put all the ranks of the Black Crow organization, how to get that rank, and what are the benefits you get from being that rank. The ranks are ordered lowest to highest.

-Automatically become Ghost soldier by joining the Black Crow, either by using Blood Cloth or by getting recruited while being inhuman.

-Benefits:
-You become able to take assassination quests from the well if any available.
-You get available items for purchase in Blood List Stele which are: [Astringent], [Anti-Poison Plaster], [Chi Refill Plaster], [Poison] (each 20 blood coins, 20BC)
-Purchasable weapons: [Zi Mu Mandarin Duck Sting] x300BC (pretty cool and fun weapon)

-Become by paying x1000BC (Blood coins) at the Blood List Stele or when using the Blood Cloth

-Benefits:
-New purchasable items which are: [Might Pellet](x50BC), [Vajra Pellet](x50BC), [Great Return Pill](x100BC), [Marrow Refining Pill](x200BC), [Smoke Grenade](x200BC), [San Ri Duan Chang San](x300BC), [Broken... cartilage powder](x300BC)
-Purchasable weapons: [Eighth grade lotus flowery] x500BC (very useful and strong)

-Become by paying x3000BC at the Blood List Stele or when using the Blood Cloth

-Benefits:
-New puchasable items which are: [Breaking Breath and Breaking Meridian Pill](x500BC), [Blood Sha Dan](x500BC), [[b]Eight sided Black Sparrow Flower Roaster[/b]](x100BC)
-Purchasable weapons: [Under the moon, a cold awn shines] x800BC (Meh...)
-The Eight sided Black Sparrow Flower Roaster is not consumable, and will show you all the members from the Black Crow organization except the last 2 ranks, they remain incognito.

-Become by paying x9000BC at the Blood List Stele or when using the Blood Cloth

-Benefits:
-New purchasable [Serpent Ganoderma](x1500BC)
-You get a new interaction (you access the Interaction menu by clicking C and going to Interaction) called "killer order", it allows you to mark any NPC on the map with a "Death Prediction"
Assuming you were not the one that marked the target, if you make the target hate you enough and then kill them, the maximum blood coins you can get from killing the target is x1000BC.
Other than that, when you mark someone with Death prediction, assassins will eventually attack the target in hope of killing him.

-This one is tricky, you are required to kill the current Black Crow leader to take away his rank, the issue is not killing him, the issue is finding out who he is, its next to impossible.
If you try using the Blood Cloth to ask, they will tell you to check the roaster, although their name is censored under [one's ancestors], they will still appear in one of the sections of the lower ranks. You still won't be able to know who exactly is the [one's ancestors] but at least you have a candidate list. (Thanks to ParagonYew for discovering this)

-Benefits: oh boy does it get good
-You get 2 new interactions "Kill Order" and "Death notice"
-Death notice allows you to mark anyone on the map, the target you mark gets listed on the assassination list in the well free of charge. So you can basically request assassinations for free and if you have a different character, you can do the assassinations and aquire blood coins.
-Kill Order Same as Death notice, but with this one you chose a sect, and once you do ALL MEMBERS OF THAT SECT get listed as targets on the assassination list.

Here I will try going over some of the items I deemed valuable and ones which I think require some clarification:

Acquired from one's ancestors treasure chest
You need to activate it first in your Meridians

To use it, you must sneak up to a target and go to interact and chose "raid", the move is instant, and if you can deal enough damage with it it will instantly knock out the target without the target ever knowing you did it, very useful skill, sometimes on targets that have a lot of Vigor it will only reduce their HP and they will instantly attack you.

I can't confirm what "Murderous energy" means but if I would have to guess, when you eliminate someone with a "Death prediction", as mentioned previously, and if you are not the one who set the Death prediction on that target, you get "Murderous look" stacks

These stacks do expire, and I will assume they mean the same thing as "Murderous energy", so in other words, this is kinda useless since the stacks expire, and I've never ran into an NPC that randomly had the Death Prediction, except for NPCs that I gave the death prediction to my self.

Same explanation as Crow shadow iron scales.

Acquired from the shop Equipment section 300BC
This can be really fun to play around with.

Acquired from the shop Equipment section 500BC
From my testing, this indeed works with all skills, borderline broken and mega useful! I even wear it if I don't use any Kunai skills.

Acquired from the shop Equipment section 800BC

Acquired from the shop Props section 200BC
Can be a lifesaver at times

Acquired from the shop Props section 100BC
It doesn't get consumed when using, it will show members of the Black Crow faction, except the ones that are high enough rank, but you will still find out how many of them are there.
