My B&B Can Be Upgraded: Guests from All over the World Give Crazy Rewards

[Upgrade flow]+[Brainless cool article]+[With system]+[No CP] Faced with the dilemma of being unemployed after graduation, Shen Xinglan returned home to inherit his grandfather's inheritance and transformed the farm into an ancient style B&B in an attempt to make a comeback. However, when the epidemic was banned, he lost all his pants. Just as he was about to sell his B&B to replenish his blood, Shen Xinglan found a jade pendant from his grandfather's relics. "Ding, the Wanjie B&B system is being activated!" So... Guests in ancient times stayed at her inn, called the bathtub with hot water "Fairy Bucket", took a sip of milk tea and shouted: "This kind of wine should only be found in heaven!" When a person from the future tasted steaming braised pork for the first time, his eyes were red and he cried with snot and tears: "It turns out that food from tens of thousands of years ago tasted like this!" After saying that, he turned around and filled up the B&B VIP with all the newly issued energy coins. Even the survivors of the apocalypse couldn't put it down holding the laser gun she sold, and asked her: "Boss, when will the last super rocket launcher arrive?" Seeing the piles of ancient antiques, the maxed-out cards with future star coins, the boxes full of apocalyptic crystal cores, and the string of zeros in bank card balances in the real world, Shen Xinglan almost burst out laughing. While other people work hard to make life-or-death mistakes, she wins by opening a B&B across dimensions!
