Blox Fruits is a massive open-world adventure game divided into three seas. The moment you first spawn in the game, you start with the First Sea, and as you progress, you will unlock the next two as well. Most fans believe it’s the Second Sea where things get interesting. However, it can get difficult since you need to fulfill certain quests and basic requirements. Make your life easier as we teach you how to get to the Second Sea in Blox Fruits.
How to Get to Second Sea in Blox Fruits
Getting to the Second Sea in Blox Fruits will not be simple since you must grind to cross at least level 700. You can gain XP by completing quests and defeating the NPCs and bosses on various islands. You can consider redeeming the latest Blox Fruits codes to get twice the XP gain during your battles. With that said, follow these steps to get to the next area.
1. Talk to the Military Detective
Once you have crossed the level threshold, completing a simple quest will give you access to the Second Sea. For this, visit the Prison island located to the west of the Fountain City. If you haven’t discovered all the islands and have trouble finding the Prison, check out the Blox Fruits Map in our guide.

Having reached the Prison, talk to the MISC NPC called the Military Detective. He will assign you a quest to track down Don Swan, who is hiding with the Ice Admiral in the Frozen Village. He will also give you the secret key to a door that hides the Ice Admiral. Note that you won’t get this quest unless you are level 700 and above.
2. Defeat the Ice Admiral
Now, all you need to do is head to the Frozen Village and go inside the secret cave, where you learned Flash Step, Aura, and Air Jump techniques from the Ability Teacher NPC. Notice that there is a small brown door inside the cave. Behind this door lies the Ice Admiral NPC, a level 700 boss.

This boss will use the abilities of the Ice Fruit, including Ice Surge and Glacial Epoch. The former can be dodged by keeping distance, while the latter by using Air Jumps and Flash Steps.
Overall, you must use ranged attacks and instinct and equip yourself with high-damage-dealing fruit. Check out our Blox Fruits tier list to pick the best one. Remember these tips; you will be good enough to beat the Ice Admiral in no time.
3. Transport to the Second Sea
Having defeated the boss, you can now interact with the Experienced Captain located in the Middle Town. Finally, you will get transported to the Second Sea. The same NPC in the Second Sea will transport you to the Third Sea when you complete the requirements there.

And that’s how you get to the Second Sea in Blox Fruits. Were you able to defeat the Ice Admiral by following the tips we shared? Let us know in the comments below!
