The Great Era of Lost Navigation

Synopsis: Lost your bearings, eh? Because the star beacon is extinguished, and I did it.I have many titles too. I was once called "Useless small UP master" and "King of bad stories", but that was all before I transmigrated.Later, they called me "Navigator approaching the gods", "Lord of Time", "Great Swordsman", which were actually a bit exaggerated.My favorite title is still "The older brother Sonya, my sister, loves most"."Of course, she's my adopted sister".A work by a veteran author, who just completed a novel with two thousand subscriptions and three million words: 《I Teach Kendo in Tokyo》.
