Don't Run! I Can Only Protect All of Humanity If You Take My Advice

Hao Jian transmigrates to a parallel world after spiritual qi revival. He gets a System that makes him stronger whenever someone takes his advice. From that moment on, whenever one enemy after another appears before him, Hao Jian offers advice before he even draws his sword. “Little beast, eating me will break your teeth and ruin your tail. I suggest you eat your own kind instead. Fewer of them means more food for everyone...” “Old doctor, you're teaching the wrong posture. If your lower body isn't steady, the earth will shake. Squat a little lower and you'll relieve that constipation...” “Crafty fellow, I hear you pass your skills on to men, but not women? I suggest doing more charity work at the hospital. Put your hands to work often, and you'll get results sooner.” “Old Wang next door, there's always a guest at home when your wife takes a bath. I suggest getting a DNA test right away and taking a good look at your family ties...” As one outrageous suggestion after another is taken to heart, years later, people gradually realize that Hao Jian, with his shameless streak that seems to embody all the world's paths, is humanity's true savior. When ferocious beasts and foreign powers try to devour humanity whole, Hao Jian holds a three-foot sword in his hand. At his call, the sword comes, and the gates of heaven open. One piece of advice, and the world is shaken. “Red-clad girl, stop! Don't be scared. I just killed a foreigner who wouldn't take my advice.” “...He's my man.” Hao Jian's eyes light up. “That's even better.”
