From the Start, I Became the Protagonist's Mother's Disciple and Was Rewarded with a Spurring System

My name is Cao Changfeng. I transmigrated into a book as the villain. Think I'll die at the protagonist's hands?

No. I awakened the [Apprenticeship System]!

[Every time you take a master, you unlock a new golden finger!]

From the start, I take the protagonist's peerlessly beautiful mother as my master.

Reward: [Discipline System]. Discipline your master in cultivation to earn rewards! Resets daily!

The protagonist's fairy-like cousin wants to cause trouble for me?

Then I'll take her as my master!

Taking the protagonist's fairy-like cousin as my master earns the [Book of Blame]: Write down a person's name and an event, and you can transfer the karmic consequences to them!

What? That old beggar by the roadside, whom the protagonist looks down on, is actually an unparalleled Great Sage with damaged foundations and a clouded Dao heart?

Master, accept this disciple's bow!

Reward: [Immortal Treasure Basin]. Put in a treasure and get back even more!

I also restore his Dao heart, and the unparalleled Great Sage becomes my guardian!

One master, one golden finger!

As my number of masters keeps growing, I become invincible without even realizing it.

When Cao Changfeng decides to deal with the protagonist blessed by fortune, he suddenly discovers:

Masters, why did you kill all the protagonists?

Leave one for me!
