The explosive power of this explosion was immense, but due to the confined nature of the underground space, the aftershocks of the explosion dispersed very quickly. In just a short time, the impact of the explosion had completely passed, and the turmoil in the oil lakes had also vanished, restoring calm to the drone.
However, Yan Fei immediately noticed that the flow of oil in the oil lake where the drone was located had changed. The viscosity of underground oil is very high, making rapid movement difficult, but this location is thousands of meters deep underground where the pressure is immense. Once a vacuum-like gap appears underground, the oil will rush toward the direction of the gap at an extraordinary speed.
