The Ambushes on Redwater River (PartⅡ)

Compared with Lotus who was watching from afar, Sylvie could see everything more clearly.

Through the walls of the mud hut, Sylvie could see that soldiers were busy repeating their single actions in good order. When a group of seven or eight worked together, they formed a whole body. Bags and iron balls piled up behind compartments were successively sent into a thick iron pipe and then they were ejected out like thunder.

Looking at it carefully, Sylvie noticed that the soldiers first lit a rope attached to the end of the iron pipe and then sparks jumped into the pipe to light the bags. The ensuing brightness was so luminous that Sylvie squinted. The firelights then instantly expanded themselves to an orange fireball which filled each pore of the pipes. The firelights expanded so much that they, together with the iron balls, were tossed out as if by a giant hand.
