After Graduation, I Relied on the Heartbeat System to Achieve Financial Freedom

Heartbeat system: Level 1: 1 yuan/heartbeat 70 yuan per minute, 4,200 yuan in revenue per hour, 100,000 yuan in one day, and 3 million yuan in one month. Level 2: 2 yuan/heartbeat Level 3: 10 yuan/heartbeat Level 4: 100 yuan/heartbeat Level 5: 10,000 yuan/heartbeat ...(It can be upgraded to millions, tens of millions, billions or even higher in the future, and special currencies or concepts can be introduced) * Upgrade method: consume the current accumulated money to reach a certain proportion/amount + complete specific "heartbeat challenges" (such as experiencing strong emotional fluctuations, completing thrilling behaviors, achieving specific life goals, etc.).
