Underwater Protection Module

★★★☆☆ 难度等级

延长水下呼吸时间。氯气+氧气在外骨骼升级站合成。

1. 概览

Underwater Protection Module 是一种 外骨骼 升级，可以大幅延长你在无人深空海洋中潜水的时间。

无人深空的水下环境是游戏中生物多样性最丰富、资源最丰富的区域之一。

除了资源，水下探索对于几个任务线和里程碑也是必需的。

Underwater Protection Module 有四个等级：C、B、A 和 S。

与大多数从空间站 Exosuit Technology Merchant 使用 Nanites 购买的 Exosuit 升级不同，Underwater Protection Modules 直接在 外骨骼 Upgrade Station 制作。

本指南涵盖了从精确配方到最高效的氯气和氧气 farming 路线，以及使用精炼器循环指数级增加氯气供应的高级技巧。

2. 配方与蓝图

Underwater Protection Module 在任何空间站的 外骨骼 Upgrade Station 制作。

Primary Recipe

Underwater Protection Module = 250x Chlorine + 100x Oxygen

在站点制作的每个模块在创建时会被分配一个随机等级（C、B、A 或 S）。

Recipe for a Single S-Class Set (Estimated)

要获得三个 S 级 Underwater Protection Module，平均需要制作约 15-20 个模块。

Full S-Class Set (3x S-Class) ≈ 3,750–5,000x Chlorine + 1,500–2,000x Oxygen

这听起来很多，但路线部分中描述的 Chlorine Expansion Loop 技术可以从少量起始原料生产数千 Chlorine。

外骨骼 Upgrade Station Location

外骨骼 Upgrade Station 位于每个空间站的左侧，当你下飞船并面对空间站核心时立即可以看到。

Adjacency Bonus Explained

无人深空为 外骨骼、飞船 和 多用途工具 升级模块使用了相邻加成系统。

  • No adjacency: Base timer only (e.g., 30s for S-class)
  • 2 adjacent modules: ~3% bonus to both adjacent modules
  • 3 adjacent modules: ~5% bonus to all three modules

为了最大化你的水下时间，将所有三个 Underwater Protection Module 垂直放置在 外骨骼 的技术插槽中。

3. 材料与获取方式

完整材料清单

🧪 Chlorine

Total needed: 3,750–5,000 (or ~100 with expansion loop)

来源 1: Refine Salt 2:1 in Medium/大型精炼机

来源 2: Mine Chlorine deposits on Toxic/Ocean planets

来源 3: Chlorine Expansion Loop (see Route section)

备注: Green-tinted mineral deposits. Salt is found in underwater minerals on ALL ocean planets.

💨 Oxygen

Total needed: 1,500–2,000

来源 1: Red flowering plants on most planets (Oxygen-Rich Plant)

来源 2: Purchase from Galactic Trade Terminals (~150 Units each)

来源 3: Refine Kelp Sac or Fungal Mould 1:2 in refiner

备注: The most reliable method is harvesting Oxygen-Rich Plants — they give 50–80 Oxygen each and respawn quickly.

🧂 Salt

Total needed: 7,500–10,000 (if not using expansion loop)

来源: Underwater mineral deposits on ALL ocean/water planets

工具: 采集光束 or 地形操纵器

备注: Salt deposits are the white/crystal underwater formations. Extremely abundant. Refine 2 Salt → 1 Chlorine.

🔄 有色金属 (Optional)

Total needed: 100 (for Oxygen refiner loop)

来源: Refine Copper, Cadmium, Emeril, or Indium

备注: Only needed if doing the advanced Chlorine Expansion Loop. Copper is found on most planets.

Farming Chlorine: The Three Methods

有三种可行的获取氯的方法，按效率从高到低排列。

  1. Chlorine Expansion Loop (BEST): Place 1 Chlorine + 2 Oxygen in a Medium or 大型精炼机. The output is 6 Chlorine. You created 5 extra Chlorine from nothing but Oxygen. Take those 5 Chlorine, add 10 more Oxygen, and get 30 Chlorine. Repeat. This exponential loop turns 1 Chlorine and sufficient Oxygen into thousands of Chlorine. Details in the Route section.
  2. Salt Refining: Dive to any ocean planet and mine Salt from underwater mineral deposits. 2 Salt refines into 1 Chlorine in any refiner. Salt is extremely abundant underwater — a 10-minute dive can yield 1,000+ Salt, which becomes 500+ Chlorine.
  3. Direct Mining: Some toxic and ocean planets have direct Chlorine deposits on land (green-tinted mineral formations). These are less common than Salt deposits but provide Chlorine without the refining step. Use your 分析面罩 to scan for them.

Farming Oxygen: The Two Best Spots

氧气是最容易大量获取的资源之一。

  1. Oxygen-Rich Plants: These red flowering plants are found on virtually every planet type. Use your scanner and look for red plant icons. Each plant yields 50–80 Oxygen when harvested with your 多用途工具. They respawn every few minutes. A single field of 10 plants can be farmed in a loop indefinitely. Mark a good spot with a 保存信标 for repeated farming.
  2. Purchase from Trade Terminals: Oxygen is sold at Galactic Trade Terminals on space stations and at minor settlements for approximately 150 Units each. If you have a solid income source (like selling Cobalt or 风暴水晶s), buying Oxygen is faster than farming. Trade terminals stock 500–2,000 Oxygen at a time.

4. 最优采集路线

这条路线针对想要尽快获得三个 S 级 Underwater Protection Module 的玩家进行了优化。

Phase 1: Initial Resource Gathering (15 minutes)

  1. Warp to an Ocean Planet — Use the 星系图 to find a system with at least one planet that shows 'Water' or 'Ocean' in its description. Paradise planets and Lush planets often have extensive oceans. The planet type does not matter as long as it has deep water.
  2. Land near the coast — Find a shoreline with easy access to both land and deep water. You want a flat area where you can place a portable refiner.
  3. Deploy a 便携精炼机 — Open the Build Menu (Z), navigate to Portable Technology, and place a 便携精炼机 on the shore. You will need 30 Oxygen + 1 Metal Plating to build it.
  4. Harvest Oxygen — While on land, scan for and harvest Oxygen-Rich Plants (red flowering plants) until you have at least 500 Oxygen. Mark this spot with a 保存信标 for later returns.
  5. Dive for Salt — Equip your 危险防护 modules, dive into the water, and mine Salt from the white crystalline underwater formations. Collect 200 Salt. Salt deposits are everywhere underwater — look for the glowing white pillars on the seafloor.
  6. Refine Salt into Chlorine — Return to shore, interact with your 便携精炼机, and refine 200 Salt into 100 Chlorine. This is your seed stock for the expansion loop.

Phase 2: Chlorine Expansion Loop (20 minutes)

这是使 farming Underwater Protection Module 变得轻而易举的核心技术。

Chlorine Expansion Loop: 1 Chlorine + 2 Oxygen → 6 Chlorine (Medium/大型精炼机)

  1. Build a 中型精炼机 — If you do not have one yet, craft it at your base (requires 100 有色金属 + 50 Di-hydrogen Jelly). Place it next to your 便携精炼机 on the shore.
  2. Start the Loop — Put your 100 Chlorine seed stock into the 中型精炼机 input. Add 200 Oxygen. The refiner will output 600 Chlorine.
  3. Expand — Take 100 of your new Chlorine, add 200 more Oxygen → 600 Chlorine output. You now have 1,100 Chlorine.
  4. Repeat — Continue the loop. Each cycle multiplies your Chlorine by approximately 5x (after subtracting the seed). After 4–5 cycles, you will have 5,000+ Chlorine — enough for your full S-class set.
  5. Replenish Oxygen as needed — If you run low on Oxygen, harvest more from nearby red plants or purchase from the local trade terminal/minor settlement.

数学原理有效，因为每个循环消耗 1 Chlorine + 2 Oxygen 并产生 6 Chlorine——每单位输入净赚 5 Chlorine。

Phase 3: Gather Additional Oxygen (10 minutes)

  1. Farm Oxygen-Rich Plants — While your Chlorine stock is building, spend time harvesting Oxygen. You need roughly 2,000 Oxygen for the full module crafting set.
  2. Alternative: Buy Oxygen — If you have excess Units, fly to a space station and purchase Oxygen from the Galactic Trade Terminal. Each terminal stocks 500–2,000 Oxygen at ~150 Units each.
  3. Alternative: Atmospheric Harvester — If you have unlocked the Atmospheric Harvester blueprint, place one at your base on a planet with Oxygen atmosphere. It passively generates Oxygen over time.

Phase 4: Craft at the 外骨骼 Upgrade Station (10 minutes)

  1. Warp to any Space Station — All stations have the 外骨骼 Upgrade Station.
  2. Locate the Upgrade Station — Left side of the station, blue holographic silhouette icon.
  3. Craft in batches — Open the crafting interface, navigate to 危险防护 → Underwater Protection Module. Craft 5 modules at a time. Check their classes — keep any S-class and A-class, discard C-class and B-class (or keep them as temporary placeholders).
  4. Repeat until three S-class — With 5,000 Chlorine and 2,000 Oxygen, you can craft 20 modules. Statistically, this should yield 1 S-class module. You may need to do a second farming run to get all three S-class modules — this is normal and expected.
  5. Install modules — Open your 外骨骼 inventory, switch to the Technology tab (rightmost slots), and place your best three Underwater Protection Modules in a vertical column for the adjacency bonus.

Phase 5: Test Your New Gear

  1. Find an ocean planet — Warp to any system with a water world.
  2. Dive deep — Jump in and watch your underwater timer. With three S-class modules, you should have 4–5 minutes of dive time.
  3. Farm Kelp Sac — While underwater, look for Kelp Sac (glowing green underwater plants). These are required for 停滞装置s and sell for 40,000 Units each raw. With your extended timer, you can now efficiently farm deep-ocean Kelp Sac patches.

5. 注意事项与技巧

⚠️ Random Class Rolls

你制作的每个 Underwater Protection Module 都有随机的等级分配。

⚠️ Technology Slot Limit

你的 外骨骼 有有限的技术插槽——通常 7-14 个，取决于你购买了多少。

⚠️ Cannot Be Repaired

如果你死亡并且 外骨骼 技术插槽损坏，Underwater Protection Module 可能损坏且必须重新制作。

⚠️ 生命维持 Still Drains on Land

Underwater Protection Module 只延长你的水下呼吸计时器。

⚠️ Does Not Stack With 生命维持 Gel

在水下使用 Life Support Gel 或 Oxygen 胶囊会补充你的 生命维持 条，但不会重置水下计时器。

💡 Pro Tip: The Nautilon Submarine Is Even Better

如果你发现自己在水下花费大量时间，建造 Nautilon Chamber 并召唤 Nautilon 潜艇 exocraft。

💡 Pro Tip: Mark Oxygen Farms

当你找到一片氧气丰富植物密集的星球时，放置一个 基地电脑 并在那里建立一个小基地。

💡 Pro Tip: Sell Excess Chlorine for Profit

如果你使用 Chlorine Expansion Loop，你可能会产生远多于模块所需的 Chlorine。

6. 额外收益与解锁内容

安装 Underwater Protection Module 开启了整个类别的游戏玩法，否则这些玩法会让人感到沮丧且有时间限制。

即时收益

  • Extended Dive Time: With three S-class modules, your underwater timer extends from ~45 seconds to nearly 5 minutes. This is enough to reach the ocean floor on most planets, explore underwater caves, and collect distant resources without frantic surfacing.
  • Stress-Free Exploration: No more watching the drowning countdown while frantically swimming toward the surface. With extended protection, underwater exploration becomes as relaxed as walking on land.
  • Deep Treasure Access: Submerged Relics, Salvageable Scrap, and sunken technology modules are often found in the deepest trenches. With proper underwater protection, you can reach these without taking damage.

解锁活动

  • Kelp Sac Farming: Kelp Sac is a key ingredient in the 停滞装置 and 聚变点火器 (15.6 million Units each). Kelp Sac only grows underwater and is most abundant in deep ocean trenches. With three S-class modules, you can efficiently farm enough Kelp Sac for multiple crafting runs. Each Kelp Sac sells for ~40,000 Units raw.
  • Dreams of the Deep Mission: This secondary questline requires extensive underwater exploration including swimming through submerged ruins, retrieving artifacts from the seafloor, and battling underwater creatures. Without adequate protection, this mission is extremely difficult. With three S-class modules, it becomes a relaxing sightseeing tour.
  • Abyssal Horror Hunting: Deep oceans are home to Abyssal Horrors — terrifying creatures that guard valuable resources. With extended dive time, you can lure them away from their hoards, grab the loot, and escape before your protection runs out. The resources they guard include 幼虫核心s (worth ~90,000 Units) and Hadal Cores (worth ~120,000 Units).
  • Underwater Base Building: Building bases underwater requires spending significant time submerged to place structures, run power lines, and install underwater glass tunnels. Extended protection makes this process far more enjoyable. Underwater bases are among the most visually stunning in the game, with glass corridors offering panoramic ocean views.
  • Fauna Discovery: Many planets require discovering underwater species to complete the Zoology milestone. These creatures are often deep-dwelling and require extended dive times to locate and scan.

经济收益

  • Chlorine Resale: As detailed in the Pro Tips, the Chlorine Expansion Loop used to farm for these modules generates massive quantities of Chlorine as a byproduct. Selling excess Chlorine to trade terminals is a reliable income stream.
  • Underwater Commodity Trading: Submerged Relics refine into valuable trade commodities. Salvageable Scrap becomes Scrap Metal (worth ~50,000 Units per stack). A dedicated underwater salvage run with proper protection can yield 2–3 million Units in an hour.
  • Nautilon Unlock Path: Building Underwater Protection Modules familiarizes you with ocean exploration, which is the prerequisite for unlocking the Nautilon submarine. The Nautilon in turn unlocks deep-sea exocraft missions from your freighter command room, which reward valuable items including 飞船 and 多用途工具 upgrade modules.
