Once you reach Inter-Knot Level 40 in Zenless Zone Zero, you can start the Is Blood Thicker Than Water side quest. You will need to speak with a distressed police officer in front of Random Play. She claims that she has lost her child inside a Hollow, and you offer to rescue them. Not long after, you will receive a message from your previous client named YourAverageSlacker. They have a special AI named Dadd-E that can help Liz advance through the Hollow and complete the commission.
ZZZ Is Blood Thicker Than Water Puzzle Solution
To complete the Is Blood Thicker Than Water side quest in Zenless Zone Zero, you must help Liz advance in the Hollow by completing three puzzle challenges. Your goal is to create a path and guide the robot through the stages while also avoiding dangerous zones.
Puzzle 1
After defeating a group of Ethereals, you can find a broken robot named Liz, who’s the so-called child of the police officer. Unfortunately, it insists on collecting all the coins nearby before you can bring it out. So, with the help of Dadd-E AI, you must create a path that the robot will mimic.
- Head right until you reach the corner.
- Go down to rooms and grab the first coin.
- Turn left to the second coin.
- Go down and then head right to reach the endpoint.
Puzzle 2
In the second stage of the Is Blood Thicker Than Water quest, you will encounter three dangerous zones that you must avoid. There is also a secret room containing a golden treasure chest that you can grab. Here is the solution:
- Head right until you reach the secret room with the chest.
- Go down one room and then turn right to grab the second coin.
- Head right again and then go down three rooms.
- Then, you must turn left and up to get the other two coins.
- Finally, you can head straight to the finish line.
Puzzle 3
The last stage of the Is Blood Thicker Than Water quest is a bit more tricky since there are more dangerous zones. The red ones will reduce your HP, while the purple ones will increase your Pressure.
- Go down one room and then turn right.
- Head down two rooms and then turn left.
- Now, just go straight to reach the finish line.
To exit the Hollow, you must fight another wave of Ethereals that will block your path. Once you’re safe, you can report to the police officer outside your shop. Completing the Is Blood Thicker Than Water quest will grant you these rewards:
- Inter-Knot Credit x250
- Polychrome x20
- Senior Investigator Log x2
- W-Engine Module x1
- Crystallized Plating Agent x2
- Denny x10,000
