System PK: Who Can Monetize Better Than Bragging?

[Overhead + system + no heroine] During the graduation season, Zhou Yuanhao and several roommates were busy submitting resumes for interviews every day, but they never found a suitable job. Several people in the dormitory couldn't help but look up to the sky and sigh. The protagonists in the novel all have systems. It would be great if we could also give them systems. Unexpectedly, this wish actually came true. There are four people in the dormitory, and each one is bound to a system. However, the system is not permanent and requires a round of PK! Whoever makes the most money using the system within a month will be the final winner and will get the permanent right to use the system. The four people in the dormitory instantly felt as if they had been given a shot of chicken blood. They no longer wanted to find jobs. They were using the system rules to make money every day. Some people are bound to the goddess harvesting system, some are bound to the food system, and some are bound to the blind date system, but what Zhou Yuanhao gets is the bragging monetization system. As long as someone brags in front of him, they can get corresponding rewards. While several roommates were busy setting up stalls, chasing goddesses, and going on blind dates, Zhou Yuanhao found food stalls, bars and other crowded places every day to listen to others bragging. He wanted to see who could be better than the bragging monetization system.
