Naruto: Reborn as Orochimaru - Chapter 277

“Do females fly??”“What?!!! I've never seen one.” Parrick said with a frown.“Then why....” he said nonchalantly pointing to the sky where a female was descending at a super sonic speed with a loud scream on the top of her lungs.Parrick gaped at the sky in disbelief. The female clearly had no wings...so how come she was up there! Also...there were no flying beastmen settlements from where the female came from!!!“Ahhhhhhhhhh!!!!!!!” the female screamed falling from such a high altitude and her scream died down the next minute.“My Lord ...we didn't save her!!!!!” Parrick gaped in utter shock and disbelief.“Her scream surely attracted a number of other males.

There was bloodshed everywhere as some died meaningless deaths, while the strong tyrannized the weak and the truth was frequently hidden. Some of the citizens had completely lost their mind, while some died on their travels. Most importantly, the words of a certain youth caused much panic in the human world. It was a time of little warmth as nights in the capital were frequently accompanied by gusts of wind and rain, and it would be covered with snow during winter. Such were the days…
