Dropped into a World Full of Zombies

Li Yun traveled to the zombie world. He was chased by a zombie and looked for shelter. Finally found a "yard"... Zombies were rampant outside, and he had to find food. He had a gun, but he had to save bullets, so he could only make a machete out of stone and iron pieces. He walked out over the courtyard wall. A machete, hacked to death a few zombies, a chase, found a few raw potatoes... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
