 As humans became more intelligent, they found new and more effective ways to kill. And as people began living in larger groups, they needed more powerful weapons to defend themselves and fight in wars.

I read "Weird Weapons". A long time ago, weapons were made to kill animals or humans. the weapons were very simple at first, but they developed stronger and more dangerous as humans became more intelligent. Inventors discovered gunpowder in China in the 10th century. this material was used to make strong weapons such as fire rockets, cannons, and bombs, and enabled to kill large numbers of people in wars. I would like to introduce one of the impressive weapons. It is trebuchet. This was used in wars as an effective machine around the sea between southern Europe and Africa in the 12th century. It could carry a heavy weight and its long arm threw rocks, burning oil, or other things that could hurt enemies. This machines was also used to throw the dead animals and people into the place where enemies were because the dead bodies might make the enemies sick and died. I did not know that even dead bodies are used in wars, and I thought it was cruel and ruthless. This book made me sad and panful. However, you should read this story to learn about the history of early people and mistakes of the past.
