Oath of Sacrifice

There is a legend circulating in the fantasy world. It is said that people in the fantasy world can be reborn through the method of sacrifice, thereby changing their fate against the will of heaven. When the legend first emerged, countless people tried to change their destiny through sacrifices, but no one succeeded. Over time, it was completely forgotten. And the method of sacrifice also dissipated over time. However, no one expected that today, tens of millions of years later, an orphan would accidentally unlock the method of sacrifice.
