Arad, Douluo Is the Strongest

This world is gradually merging with the Arad continent. This world is a world that was once a technological civilization. Twenty years ago, the plane of the Arad continent collided with this world, causing a space rift, which caused a large number of monsters to flood into the world and kill most of the human race. Humanity discovered the Terran civilization while exploring that space. It took only two years to use the Terran civilization to temporarily stabilize the status quo. The cracks were controlled and multiple walled cities were built around the world. The remaining humans survived inside, while outside the city walls there were only ruins and monsters from Arad. They hid and cracks appeared constantly to attack the city. The protagonist Lin Hao is a dnf tactics player. He was accidentally reincarnated into this world, and in this world he chose tactics to continue fighting. This novel and its characters are purely fictitious.
