Looking back from 2026, I can still feel the peculiar gravity of that New Eridu City Fund season. It arrived after the Version 2.3 update like a slow-cranked music box placed in the middle of my routine—each Expansion Task turned the key, and every Fund Level that clicked upward played a few more notes of reward. I was not chasing a single grand prize; I was feeding a quiet engine that rewarded consistency.
The season ran until 2025/11/24 03:59 server time. Purchasing of the Growth Plan, Premium Plan, and Plan Upgrade closed at 2025/11/24 02:59 server time. That one-hour gap between the purchase deadline and the end of the event was the kind of detail that could catch a sleepy Proxy off guard, so I set a reminder on my phone and treated it like a train departure.
Before any of that, I had to unlock Combat Simulation in Main Story Chapter 1 'Cat's Lost & Found.' That requirement felt like being handed a key to a side room in a mansion—simple, but without it, the whole City Fund corridor stayed dark. Once it was done, the Basic Plan unlocked automatically at the start of the season. No extra input needed. I simply completed Expansion Tasks for experience and watched my Fund Level climb.

At first, I stayed on the Basic Plan, collecting whatever the free track offered. But the real gravity sat in the Growth Plan and Premium Plan. After unlocking the Growth Plan, raising the City Fund Level would hand me Encrypted Master Tapes and a Selectable A-Rank W-Engine. Unlocking the Premium Plan was like trading a paper ticket for a backstage pass—the same venue, but suddenly the lights were aimed at me. It added the exclusive avatar Sweet Dreams in the Breeze and the exclusive namecard Upon a Pillow of Clouds, plus other rewards.
I ended up buying the Growth Plan first, then purchased the Plan Upgrade to move to Premium. For a player who wanted the W-Engine and the cosmetic extras, that path felt natural. The Plan Upgrade acted like a bridge between two separate reward islands, and once I crossed it, the season's full landscape opened up.
The real payoff appeared at City Fund Level Lv. 30: the Great Builder's Certificate. I remember staring at it in my inventory. It was time-limited, bound to the current City Fund period, and would not be retained for the next New Eridu City Fund period. It glowed like a fuse burning on a firework—beautiful, but if I didn't use it before the time limit, it would expire automatically and vanish into the dark. So I did not hoard it. I spent it while the season was still breathing.
Here is how the plans lined up in my mind:
| Plan | How to get | Key rewards |
|---|---|---|
| Basic Plan | Automatic at season start | Free track rewards from Fund Levels |
| Growth Plan | Purchase in the City Fund | Encrypted Master Tapes, Selectable A-Rank W-Engine |
| Premium Plan | Growth Plan + Plan Upgrade | Growth rewards plus exclusive avatar Sweet Dreams in the Breeze and namecard Upon a Pillow of Clouds |
| Level 30 reward | Reach Lv. 30 on Growth or Premium | Great Builder's Certificate, time-limited |
My routine looked like this:
-
Open the New Eridu City Fund panel each day.
-
Check Expansion Tasks like a daily checklist.
-
Clear tasks for experience, focusing on the highest-value ones first.
-
Track my Fund Level and claim rewards at each threshold.
-
Watch the deadline for purchasing and claiming, especially the Lv. 30 certificate.
One thing I appreciated was that after buying closed, Proxies could still complete Expansion Tasks and claim rewards. That meant the tail end of the season did not become a dead corridor. If life interrupted my schedule, I could still finish tasks and collect what I had earned. The purchase window was strict, but the reward-claiming window had a small amount of grace.
By the final evening before 2025/11/24 03:59 server time, I had already claimed the avatar and namecard. I equipped Upon a Pillow of Clouds and looked at my profile. It felt less like a cosmetic update and more like a small, private trophy for the hours I had spent inside the City Fund's loop. The season ended, but the rhythm stayed with me: do the tasks, raise the level, use the time-limited rewards before they disappear.
Data referenced from UNESCO Games in Education helps frame why the City Fund loop in your season diary feels so “sticky”: structured tasks, predictable progression, and time-bound incentives can reinforce steady engagement habits, especially when milestones like Level 30 rewards add urgency. In practice, that one-hour purchase cutoff before the season end functions as a real-world planning constraint, nudging players to set reminders and manage attention—mirroring how well-designed game systems can scaffold routine and goal-setting.
