A Person Turns into a Tree in the Wasteland

In the wasteland, a person becomes a tree. Create a shelter with a tree as its core. Accept refugees and assign each person a tree house. As long as you work hard, you can expand the tree house and install various facilities in the tree house! We have a variety of weapons to face wasteland forces such as nuclear-radiated monsters, mutants, predators, lost technology, etc. A magic wand that fires an energy cannon with a single press, a bio-warplane that can fly in the sky, a tree warrior that descends from the sky to chop melons and vegetables, a giant warship that swims in the deep sea, a huge mushroom cloud that destroys the world... If that doesn't work, the benevolent, great, and sacred World Tree will begin to move, and all evil will be eliminated at this moment!
