Stepping on the Demoness to become the strongest

In my previous life, I was half a move short and ultimately failed to reach the summit.
Having traveled back to the past, this time... I want to become the strongest in this world!
To become the strongest in this world, one only needs three simple steps:
1. Pick up a newly-transferred Demonic Sect Enchantress off the streets.
2. Subdue and vanquish the demon.
3. Take her cultivation technique for myself.
Awesome! I'm already invincible!

Years later, Yan Yu, who had earned the title of "the strongest," was interviewed on television:
Host: To whom do you want to give thanks for your success today?
Yan Yu: I'd like to thank a very important woman to me.
Host (eyes lighting up): Oh, is she your wise and virtuous wife?
Yan Yu: No, consider her a stepping stone, I suppose.
Host (wiping sweat): Then... what about the other members of your team? They must have helped you as well, right?
Yan Yu: ... How could there possibly be only one stepping stone on the path to godhood?
