On the day Qin Mu was blocked by the landlord at the door asking for rent, a message suddenly popped up on his phone: After eight o'clock tonight, people in this building cannot lie. He thought someone was playing a prank, but the landlord revealed everything about rent collection in front of him. Before Qin Mu could react, the second rule was refreshed: Those who tell the truth will be rewarded one hundred yuan per sentence. He glanced at the balance on his phone and then at the landlord who was still breaking the news. This world seems to be starting to go wrong.
