I sold the system to the saints in the prehistoric times and I lost money.

The creatures of the ancient world, after experiencing the Long-Han Tribulation, the Lich Tribulation, and the Conferred God Tribulation, established a system based on class and hierarchy.
But something called a system has completely broken the ancient pattern. The saints are all greedy for the system. They have opened hundreds of millions of merits, but no usable system has been developed. The saint said that this wave of losses is numb.
