I Really Just Want to Be Polite and Cultivate Immortality

This is a desperate world where monsters are rampant and people cannibalize people. Until Ye Xiao traveled through time and found that the monsters here were of extremely poor quality. Fortunately, he has the Kunlun Mirror: Reading papers on all methods is like getting started, and cultivating immortality is like copying homework. So... "I am Ye Xiao, a college student who knew the law and observed etiquette in his previous life." "The monsters in this world are so rude. They tried to attack me. They really lack education." "So, from now on, saying no to being rude starts with you." The polite young man Ye Xiao persuaded the dying demon at his feet, smiling like a spring breeze and saying: "Do you understand?" "Alas...." "I just want to be polite and cultivate immortality. If you insist on forcing me... I'll beat you to death." This book is also called: "I Really Just Want to Be Polite and Cultivation to Immortality, Don't Force Me to Beat You to Death" "Kunlun Mirror Forces Me to Become an Immortal"
