Soul Penetration: Why Does My System Have a Trial Period?

(Soul penetration + multiple female protagonists + decisive killing + invincibility + system + no procrastination + no leveling up) (Also known as: The Road to the Immortal King: Start by conquering the Saint) I had great luck at the beginning, but I didn't expect that my soul would be broken unexpectedly. The good news is that it comes with a system, but the bad news is that the system comes with a trial period. Chen Xuan: No, the system still has a trial period? You have to complete the task before you can draw a lottery, what a cow-horse system? To be honest, if this system is given to dogs, even dogs... "Ding, congratulations to the host for triggering the mission: capture the saint and become a Taoist companion with her." System: Come on, keep barking, this system, what's wrong with the dog? Chen Xuan: Give it to a dog. The dog will definitely not be able to use it, so let me do it.
