Day two

Bibi was at the desert, her shot gone even further than I thought but luckily it was stopped by tank.I put my feet exactly on hers and when I got closer to her I heard a creak, the gun barrel of the tank is moving towards Bibi! I could hear my heart throbbing. Then I knew what was going on, when the tank was abandoned, they must have forgotten to put on the brakes.But when i was picking up the ball, i realized that the armor plating was vibrating, it's the throbbing of the tank's engine. I screamed at Bibi to run but she did not instead she was throwing rocks and yelling at the tank.
