Tiny Times 4 answered! How did that fire happen?
The fire in Tiny Times 4 happened at the end of the movie. The protagonist, Lin Xiao, returned to the modern world after completing his transmigration and found that the entire city had been destroyed. According to the description in the movie, the fire was caused by a person called " Shadow." The shadow was a mysterious figure. His identity and background had always been unclear. However, the movie hinted that the black shadow might be related to the fire. The shadow had already started planning this incident before the fire broke out, and his figure had left traces in the fire. These traces might be evidence that he had planned the fire. The movie also mentioned that the fuel used by the shadow might be a special material that could burn quickly and produce high temperatures in a fire. Therefore, the fire caused by the shadow could be a very dangerous fire that destroyed the city.
