Hey there, fellow Proxy! I know you're itching to keep up with Zhu Yuan and Qingyi in that Hollow, and that Invisible Assistant quest in Chapter 2's Interlude is the ticket. Don't worry, I've been there too—those circuit puzzles can feel like a rogue Bangboo short-circuiting your plans. While the mission is straightforward, those puzzles are unavoidable gates you need to pass. It reminds me a lot of those brain-teasers we faced earlier, like hunting the "suspicious shadow" at Waterfall Soup. It's just another way Zenless Zone Zero feels like a slick, urban cousin to Genshin Impact, blending action with these neat little logic tests. The good news? Once you know the trick, these circuits are smoother to solve than a perfectly-tuned engine block.
Let's walk through it together. After the cutscene with our favorite Public Security agents, your job is simple: follow the target as directed. You'll be hopping across conveyor belts and hitting red buttons to reveal Denny pickups—always a welcome sight! Once you descend via the target TV screen and handle a quick skirmish, the real puzzle fun begins.
Here’s the core mechanic: you solve each puzzle by having your Bangboo hit the circuit components until they align into a complete, glowing pathway. Think of it like tuning an old radio—you keep twisting the dial until the static clears and the signal comes in crystal clear. When Fairy gives you the all-clear, you're set. Here are the step-by-step solutions:
Circuit Puzzle Solutions:
| Puzzle Number | Solution (From Starting Position) |
|---|---|
| First Puzzle | Press Right twice. |
| Second Puzzle | Press Right. |
| Third Puzzle | Press Right, Down, Right twice, Down, Right twice. |
Follow that sequence, and you'll have those circuits humming like a choir of perfectly synchronized machines.
⚔️ How To Defeat The Invisible Assistant Boss
The Best Agent To Use
Right after you fix the last circuit, the mission escalates. You'll face a wave of weaker Ethereals, culminating in a mini-boss fight against a brute. The game suggests using Ether or Ice-Attribute Agents for maximum efficiency. Here's my take:
-
Zhu Yuan is Your Star 🌟: This mission is a rare chance to play as her before trying your luck in the Signal Search. She's an Ether-Attack character, and her unique speed and style are an absolute blast. Using her here is like test-driving a prototype hypercar—a thrilling, exclusive experience.
-
The Speedrun Squad ⚡: If you're all about efficiency, pair Nicole (Ether) with Soukaku (Ice). Their combined Attribute buffs will shred the boss's health bar faster than a data-virus corrupting a hard drive. This combo is brutally effective.
🎁 The Invisible Assistant Rewards
Polychrome, Logs, And More
After the dust settles, there's a brief scene where Zhu Yuan and Qingyi wrap things up with their target, Carlo Maroon. Qingyi senses someone else was there (that's us!), but doesn't quite pin it on Phaethon. The agent banter alone might make you wish they were permanently on your squad!
Then comes the best part—the rewards. Completing the Invisible Assistant quest nets you a nice haul:
-
450 EXP
-
Polychrome 💎
-
Denny 💰
-
Bangboo Algorithm Modules
-
Official Investigator Logs 📄
For any Proxy running low on resources, this is a solid boost. Honestly, the puzzles were the trickiest part; the final fight, by comparison, is straightforward. If you follow this guide, the whole quest should take you 15 minutes tops. Now get out there and ace it!
