1. Every world must have an orthodox Son of Destiny (comes with World Favor, genuine system)
2. You only bind low-level passers-by with no luck, no background, and no future.
3. You give the host the authority, resources, combat power, and information gap to crush the genuine protagonist.
4. The only mission: subvert the destiny and kill the orthodox protagonist of this world
5. The moment the task is completed, the host's lifespan returns to zero and he will die without exception.
6. The stronger the host and the more thorough it is in killing the protagonist, the more universe origin you get.
7. You are immortal, travel infinitely, and watch generations of hosts fall from their peak.
8. Add that a is the original world system and b is ourselves.
