How to recharge Zenless Zone Zero most cost-effectively?

Zenless Zone Zero(CN) 3.1 "A Long Farewell" launched on July 29, 2026. The official announcement clearly stated: "The first-time double bonus for Monochrome purchases in the shop will be reset, with each Monochrome(CN) tier reset for 1 first-time double opportunity." This sentence determines the answer to all "how to top up most cost-effectively in Zenless Zone Zero(CN)" questions for the next two months — it's not about comparing which platform is a few yuan cheaper, but about comparing who stacks the three layers of dividends first: first-time double + Inter-Knot Membership (CN) + version free resources.

First, Recognize Two Kinds of "Money"

Zenless Zone Zero(CN) CN server top-up has only one chain: RMB → Monochrome(CN) → exchange 1:1 for Polychrome → gacha (160 Polychrome/pull). Inter-Knot Membership doesn't directly add to the Monochrome pool, but gives 300 Monochrome + 90 Polychrome × 30 days. So "how to top up most cost-effectively" breaks into two questions: How to allocate first-time doubles across Monochrome tiers? When to buy the membership?
 

Real Yield of 6 First-Time Double Tiers

CN server Monochrome tiers and first-time double amounts (after 3.1 reset, each tier only once):

During the double period, all 6 tiers have exactly the same "pulls per yuan" ratio (0.125 pulls/yuan). So "which tier is cost-effective" is a false proposition during the double period; what you really need to calculate is: how much is your budget, how many limited characters to pull, how many days left on membership.

Inter-Knot Membership is an Independent Layer of Dividend

30 yuan membership = 300 Monochrome + 2700 Polychrome = 3000 Polychrome equivalent = 18.75 pulls, cost per pull 1.6 yuan. It doesn't occupy a first-time double tier, doesn't conflict with Monochrome, and gives daily login freebies. In any top-up order, membership must rank first — open membership then eat first-time doubles, equals grabbing an extra 18.75 pulls layer on top of Monochrome doubles.

3.1 Version Recommended Top-Up Order (Total Budget in Three Tiers)

Budget within 100 yuan (micro-spender / student)
1. Inter-Knot Membership 30 yuan (18.75 pulls equivalent)
2. Monochrome 6 yuan first-time double (0.75 pull)
3. Monochrome 30 yuan first-time double (3.75 pulls)
4. Monochrome 98 yuan first-time double (12.25 pulls)
Total 164 yuan? No, if budget capped within 100, only do the first two steps: membership 30 + 30 Monochrome first-time double = 30 + 3.75 = 33.75 pulls equivalent for 60 yuan; remaining 40 yuan can't afford 98 first-time double so save for next version. Core principle: membership is mandatory, the 98 tier is the psychological anchor for first-time double cost-performance.

Budget 300–500 yuan (small monthly card advanced)
Membership 30 + 98 first-time double + 198 first-time double = 326 yuan, getting 18.75+12.25+24.75=55.75 pulls. Remiel is a full-version resident frequency band in 3.1 (no split into first/second half), 55 pulls plus version gift 1600 Polychrome (10 pulls) + 20 Master Tapes (20 pulls) = around 85 pulls, close to S-rank hard pity 90, suitable for players who "only pull Remiel, don't chase Sigrid".

Budget 1000 yuan+ (dual limited chaser)
Membership 30 + 6/30/98/198/328/648 six-tier first-time doubles all eaten = 1308 yuan, Monochrome doubles total 26160 Monochrome = 163.5 pulls, plus membership 18.75 = 182.25 pulls, plus version free 1600 Polychrome + 20 Master Tapes + preview 300 Polychrome + sign-in 480 Polychrome ≈ 35 pulls, total resources 217 pulls. Remiel + Sigrid two S-ranks each 90 pity secured, with 37 pulls left for 3.2.

Three Reverse Operations to Avoid

1. Don't rush 648 first then fill small tiers: During double period all tiers have same unit price; spending the whole budget on big tiers first wastes the small-tier first-time doubles (next reset waits for a version).
2. Don't renew membership when over 179 days remain: Rule is hard-coded ≥179 days cannot renew, forcing purchase only refunds 330 Monochrome (3.3 pulls), 30 yuan for 3.3 pulls is worse than non-first-time 648.
3. Don't use Monochrome to pull standard banner directly: Encrypted Master Tapes (limited) and original Master Tapes (standard) are separate; Polychrome from Monochrome should prioritize Remiel's "Paradise Lost" frequency band, Sigrid's "Until the Sky Falls" is second half, keep pulls don't all-in.

How Channel Price Difference Factors into "Most Cost-Effective"

Official in-game direct top-up is safest. CN server iOS using HoYoverse web top-up avoids Apple IAP tax; Android pays directly via HoYoverse Pass. Overseas players using Visa for global server is another USD pricing set, not merged into CN server discussion. 94LIVES as an aggregator top-up's meaning in CN server scenario: Monochrome all tiers and Inter-Knot Membership listed prices lower than official store discounted price, after submitting UID customer service manually processes via official payment channel arriving in 1 minute, first-time double and membership rules identical to official (platform only acts as intermediary, no password). For example, during 3.1 first-time double eating 98+198+648 three tiers, 94LIVES discount spread basically covers a fraction of another Inter-Knot Membership; if just buying a monthly card, in-game click is faster. Treat "channel discount" as a fourth minor dividend layer outside first-time double, don't reverse priorities to save a few yuan and give up first-time tiers.

One-Line Conclusion

How to top up most cost-effectively in Zenless Zone Zero(CN) = Open Inter-Knot Membership first → then eat first-time doubles from 98 tier upward by budget → eating all 6 tiers prioritized over repeating 648 → version free resources (1600 Polychrome + 20 Master Tapes + sign-in) counted last for total pulls. In a double-reset version like 3.1, what you miss is not a few yuan difference, but the once-per-lifetime double window of each tier.
