With Fang Yu's lifespan, what can he trade? Fortunately, this is a two-way trading system. While Fang Yu trades his lifespan with the system, he can also use his own abilities to trade with other people's lifespans. What's the point of trading one to one? One to ten is almost the same, and he won't do any business that doesn't make money.
