Lin Jin is a mediocre, laid-back junior at Jiangcheng University, with rock-bottom grades. He scrapes by working odd jobs and supports his adorable little sister. No one knows he is "Ash," a mercenary king who survived battlefields overseas. Even fewer know he is the specially appointed chief instructor of Zhenhai, China's special forces unit for people with extraordinary abilities: "Number 001," who refuses a rank and doesn't appear on the rankings. A rich bully picks a fight? He gets a face-slapping without a second thought. A criminal syndicate? Wiped out overnight. Then a rift to Another World tears open the sky, and his former classmates become soldiers defending the city. Only then does the unassuming slacker finally draw the blade that once burned whole worlds to ash. Above the rankings, there is still one person. He is flipping skewers behind a barbecue shop. His name is Lin Jin.
I like to read novels where the protagonist is low-key and pretends to be a villain but slaps the villain in the face. Come on, author!
