The check-in system made me rich overnight

"Ding! Qualified host detected, beginning binding process." "Binding successful! Check-in system 888 at your service." "Today's check-in task: Host, please proceed to Century Square for check-in. Check-in reward: To be unlocked." In the crowded subway, Ruan Qiqi listened to the sudden sound echoing in her mind, sending shivers down her spine. What was that sound? Could it be a ghost? In broad daylight, she couldn't be that unlucky, right? "This system is the 888th check-in system under the highest mainframe of the Atlantis civilization. All procedures are absolutely legal and legitimate. Host, please rest assured to check-in. After successful check-in, the system will provide rewards." Ruan Qiqi looked at the virtual screen that suddenly appeared in front of her, along with the string of text above. She felt nervous all of a sudden. What if people around her saw this bold display? "Host, please rest assured. The virtual screen of the system can only be seen by the host." Phew, that's a relief. Ruan Qiqi breathed a sigh of relief. She didn't know how to explain if others saw this. But wait, rewards for check-ins? What exactly constitutes a check-in? "Host, please proceed to the designated location within 24 hours to complete the check-in task." The designated location? Oh, Century Square, conveniently located across from her internship company. As the subway arrived at the station, Ruan Qiqi checked the time. She still had 20 minutes before her work started. Should she go to Century Square first? Century Square at 8:40 in the morning was relatively empty. Just as Ruan Qiqi stepped through the entrance gates of Century Square, the system notified her of successful check-in. "Ding! Congratulations, host, on successfully checking in for the first day. You are rewarded with full ownership of Century Square. Please pay attention to receive." Hearing the system's announcement, Ruan Qiqi was dumbfounded. Is this... is this real? Although novels feature various extravagant systems that shower protagonists with gifts every day, this was reality. How could she so easily obtain ownership of such a large shopping mall? Her phone rang at this moment, with no caller ID. But seeing the area code, Ruan Qiqi still answered. "Hello?" "Hello, is this Miss Ruan Qiqi?" "Yes, who is this?" Just by the voice, Ruan Qiqi couldn't tell who was on the other end. "Hello, Miss Ruan, I'm Wang Zhou, the property manager of Century Square. You can call me Xiao Zhou or Xiao Wang. First of all, congratulations on becoming the owner of Century Square. I'm calling to inquire whether you're willing to continue authorizing our company for property management." Wang Zhou was genuinely nervous. Century Square suddenly changing ownership caught him completely off guard. He had made this call based on the relationship with the previous owner, which took quite some effort. Ruan Qiqi was stunned by Wang Zhou's string of words. It's... it's real! Century Square had indeed become her property, and it wasn't the system deceiving her! "Miss Ruan? Miss Ruan? Are you still there?" The call hadn't ended, but there was no response from the other end, causing Wang Zhou's anxiety to rise again. "Ah! Ah, I'm here, about property management authorization, I'll call you back at noon. I don't have time this morning." Ruan Qiqi just came to her senses, suddenly realizing she had to go to work. She hurriedly ran out of Century Square towards the office building across the street. "Okay, Miss Ruan, feel free to call me anytime." Ruan Qiqi casually responded before hanging up the phone. Looking at her phone, she realized she had less than 10 minutes before 9 o'clock. Oh my goodness! She's going to be late for work!
