Zheng Qian had always worked hard to earn money, hoping to live off bank interest and achieve his dream of 'lying flat' (a relaxed, minimalist lifestyle).
When the apocalypse descended, he obtained a system called the "Myriad Exchange System".
For every day he survived, he would receive 1 survival point. If he accumulated 50 points, he would earn an additional 1 survival point as interest.
By exploiting the system's 'wool' (taking advantage of it), Zheng Qian survived the apocalypse with his system.
