A Brazilian social media influencer named Andre Luiz, who goes by the online name Ninja Flow, is constructing an underground bunker in Joinville, Brazil. The bunker is being built in a rural area, and Andre has been sharing updates with his over one million followers on social media. He emphasizes that keeping the location of such a shelter secret is a vital part of survival planning, especially in the event of extreme scenarios like natural disasters or emergencies. Andre has been working on the bunker by hand initially, but now uses a digger to speed up the process as the structure becomes more defined. He explains that while having a sturdy shelter is important, it’s not enough on its own. “Do not be seen,” he advises his followers. “It doesn’t matter whether you're going to make a bunker out of wood, brick or concrete. The most important thing is that it is well hidden and that you can store your supplies without anyone knowing where to find them.” Andre believes that people don’t need large amounts of money to start preparing for potential crises. He argues that a well-constructed shelter, regardless of its materials, can be life-saving. The bunker, which has been one of Andre’s most popular projects, has been featured in his videos for about two years. It is located underground in a secluded rural area and measures around 30 square meters. It is made of reinforced concrete and iron to ensure durability. To help hide the bunker from view, Andre plans to cover the area above it with vegetation, making it blend into the surrounding landscape and harder to detect from the air. Inside, he has installed lighting, stored food supplies, and placed a computer to access information if he needs to stay underground for an extended period. He claims the bunker contains enough supplies to last up to six months. In a recent video, he showed work on the bunker’s door, including sanding welds and applying a protective coat to prevent rust. He plans to weld armor plates over the entrance, comparing it to the reinforced plating of a battle tank, to make it impenetrable. Andre describes the bunker as a precautionary measure to increase his chances of survival during extreme events, rather than a guarantee of safety. His project highlights growing interest in personal preparedness and self-sufficiency, especially among those who follow his content online.
