The Trees Here Speak Elvish

Bai Wen, a military enthusiast, traveled through time and became an elf officer, but discovered this place and imagined the world of swords and magic in Central Africa. The orcs here have been equipped with breech-loading rifles and artillery. In the jungle, they defeated the elven army who were still using bows and arrows, and they retreated to the capital city. Bai Wen used the knowledge from his previous life to guide the elves in learning how to use captured thermal weapons, dig tunnels, lay traps, and fight guerrillas in the jungle to save the elven country from fire and water. The orcs were all under the influence of grass and trees, and even at night they would dream of the elven language coming from under the covers. "Boy, do you know how to tell whether there are enemy troops in the pointed-eared village? Shoot them. Those who run are enemies, and those who stand still are well-trained enemies." The orc veteran joked to the new recruit. "What, isn't it funny?" The recruit didn't smile. The trees on the roadside smiled.
