We start everything around 1am. 4 of us seperated in 2’s. 2 went up with extreme caution scared that the second floors floor give way. And 2 on the first floor. After 20 minutes of inside the building we decide to went out. We went out of the building with extreme sweat. Like we just went out of the swimming pool. And its already 2am+. So we take a break. Drink and eat some breads. After 1 hour break we went in again. The building again is full of smoke and debris. I take one nozzle and spray at the heated walls. And there extreme heat and smoke was getting out. So i let it unmaned and went to the other nozzle to adjust. Same as before. So around 4:30 we went out of the dark burnt place without any lights accept for our torchlights. Take a rest and we fell asleep until 6am.
