Under One Person: I Have Full Understanding and Am Going Crazy!

[Invincible + Cheap Tao + North China F4 + Humor + No CP] Zhao Xuanling traveled to a world under one person and was picked up as an adopted son by Zhao Fangxu. As a time traveler, he must have a system. But Zhao Xuanling's system is a little different. You can get learning points just by being mean. "Lao Deng, you asked me to fight the Heavenly Master, do you want the black-haired man to give away the white-haired man?" "Mom, Lao Deng had a foot massage at the bathing center. My sister-in-law ordered several of them. Yes, yes, yes, come quickly." "What? You have no money? No money, why are you still here?" "Come on, kneel down and serve me for free if you feel comfortable." The best sword in the world (cheap), Zhao Xuanling!
