Obtaining CDK In Blox Fruits

To get Cursed Dual Katana in Blox Fruits, you need to go to the third sea. Once you get there, you need to find an NPC named Cyrpt Master, who can be found behind the Turtle Mansion.
Once found, talk to the NPC and take his quest. When you do so, you will have the Puzzle door opened, which is located around the corner of the Mansion.

Once the door is opened, go inside of the Mansion. When you do so, you will find 2 Scrolls — Tushita and Yama. Each Scroll has three trials that you need to complete with the same sword.
Whenever you complete a scroll, you will be given 1 Alucard Fragment as a reward.

Here are all the Scroll trials and how to complete them:
Tushita Scroll Trials
1. Dock Legend
To complete the first Tushita trial, you must talk to 3 different boat dealers on three islands — Hydra, Castle and Turtle. When you are on the last page of boats, make sure to select ‘Pardon me’.
2. Sense Of Duty
To complete the second trial, kill a pirate in a Pirate Raid at the Castle.
3. Soulless
To complete Tushita’s last scroll, head to the Cake Queen and beat her before the song ends. Once it ends, you will be teleported to Heaven. Once you are teleported, you need to light three torches and defeat all enemies that spawn there.
Once you are done lighting up three torches, the door will be opened. When you get into that door, you will be teleported back to the Floating Turtle.
Yama Scroll Trials
To complete the first Yama scroll trial, you need to take damage from an NPC. While taking damage, make sure you have the Yama equipped. You will have to keep taking damage until a message appears on the screen that says ‘The scroll reacts to your achievements.‘
2. Haze Of Misery
To get this trial completed, you need to kill all NPCs having Purple marks. It is one of the hardest steps to complete in order to get CDK in Blox Fruits.
When you kill NPCS having purple marks, they will turn into different NPCs. Notably, you are required to Ghosts as well. Once you are done killing Purple Marks NPCs on all islands, you will get Alucard Fragment.
3. Fear The Reaper
To complete this trial, you need to summon Soul Reaper. Once summoned, let the Soul Reaper kill you. When you are killed by Soul Reaper, you will be teleported to Hell.
Once teleported, you will have to light up 3 torches and defeat all NPCs that spawn in the surrounding area. Apart from killing NPCs, you need to kill the Dark V2 boss.
When you do so, the door will be opened. Now, go into that door to teleport back to the Floating Turtle.

Once you are done completing these trials, you will have to interact with Alter located in front of the door. When you do so, you will have the door opened.
Once opened, go there and then kill the boss. When you do so, you will have Cursed Dual Katana obtained.
That’s all you need to know about how to get CDK in Blox Fruits.
