Dual tasks conflict. King Xie Mingyuan is responsible for the national destiny system. He must kill Queen Shen Zhiyi to continue the dynasty.
The fast-traveling girl Shen Zhiyi carries a strategy system. She needs to make the king fall in love with her and kill him before she can return home.
Special mechanism: Both of them can see some system prompts (but they don't know that the other party also has the system). Death triggers reincarnation reset, retaining some memories. Each reincarnation identity/time/place changes.
