How to build a hut in the wild?

Cut a small tree, the thickness can be at arm's length, be smart, don't cut foam materials such as kapok, it will break the load. Secondly, find two big trees that are not far away, but shorter than the length of the small trees just now. Then, peel off the skin of the small tree, twist it into a rope, and fix the two ends of the small tree on two big trees, so that you have a beam. Then, make purlins from the branches of small trees, fix the upper ends on the beams made of small trees, and put the lower ends on the ground. Note that the purlin is about the same length. Then, peel bark everywhere to make tiles. Tiles can be fixed on purlins with wooden sticks. Pay attention to pressing up and down to facilitate drainage. Finally, block both ends with branches with leaves to prevent wind. Dig a drain around the hut, and the mud will be pressed against the tile bottom of the hut to prevent the water from flowing back. By the way, new mud can prevent snakes. As for the engine room fire, this is more complicated. I think you have to use bricks, at least stones, and play with the chimney. This is a mason's job, so I won't say much if I'm not familiar with it.
