Last time we talked about preparing for adventure. Because of my concern, I hurried to greet them after eating. Come to the railway and prepare to cross. After my brother and Kun Kun passed through the culvert, I turned around and gave me a fright: the train roared by, but Binbin and Del were not seen. Oh, my God, did they cross the tracks? No ... I can't imagine. To be honest afterwards, when I saw this, the first thing that came to my mind was what I just thought, and I couldn't think of anything else at all. Soon, two little people came out of another small culvert hole. I calmed down and taught them a lesson. After this episode, we continue to explore this land. I ran to a small high slope inside and they followed me. Standing on it and looking again, I saw several tower-shaped things standing not far away, which should be used to store things. (Later, I found that it didn't look far, but it was far away, and it was still very big. ) We ran to a row of houses that looked close, and when we arrived, we found what seemed to be abandoned factories. After playing hide-and-seek for a while, I got bored and came out. Climbed up a slightly higher mound, looked again and found it was a cement wall. Just then, Binbin suddenly slipped. Haha, I saw that the grass slipped. That der 'der slipped on purpose, but it backfired and his big ass fell! We ran to the concrete wall. When I arrived, I found it was a square pit with a concrete bottom. There are many stones and water in it, and the water has turned into ice. Our stone smashed, smashed and ran away. Hehe, now that I think about it, I really can't do anything well. When I was running, I saw a deep pit with a mouth one meter square. Because the bottom is full of hay, you can't see how deep it is, and the pit wall is also full of hay. Like a natural bonfire pit. We are very excited and ready to light it. I found a stick, picked out a plastic bag, lit it with a lighter, and went deep into the pit. When the plastic bag burns, the plastic oil drips down and then ignites a hay. At first, the fire was very small, just a flame, which gradually increased several times, as if it were a roar, and the flame was off the ground 1 meter high. Boy, I was scared when I saw it: "Step on it!" ? "The der 'der not only didn't jump, but also held a pile of grass at a distance. I quickly thought, what can I do? There is no time to draw water, there is no one nearby, and it looks like grass everywhere. Once the fire spreads, it will be terrible. I quickly stepped on it with my foot. Whether there is a fire in the pit or not, put out the spreading flame first. I calculated the wind direction and stepped on it. Ha, that's really warm, but it makes me anxious. That Kun Kun didn't know the seriousness of the matter. When he saw me like that, he laughed loudly and asked me to put out the fire and give him a cynical meal. That derder is cute, too Seeing that I was in such a hurry (actually pretending), I lit a fire with a stick and spit in the pit. Binbin was smart enough to pull out all the unburned grass to prevent the fire from spreading. In fact, the fire is nothing at all, and it is impossible to spread, because to tell the truth, the grass around it looks dry, but it is actually wet, but it looks yellow outside. Later, the fire went out, and Binbin didn't burn as far as a circle of grass, but burned a circle of potholes. Smoke billowed from the pit after burning, and I knew that the moisture in the grass absorbed heat and became transpiration. Then I took the opportunity to say, derder, is this fire happy? Later, before I finished, derder interrupted me. The little black face smiled and said, "Happy." I pulled my face down: "Don't do this in the future." "oh"
