I've Transmigrated into a Book, So Why Marry the Heroine Instead of the Villain?

[One Female Lead] + [Scheming Man Transmigrates into a Book vs. Reborn Assassin Woman] + [Automatic Leveling] + [Sex Before Love] + [Will Do Anything to Achieve His Goals]

Before transmigrating into a book, Xiao Ce had two wishes:

1. Become someone like the Sweeping Monk.

2. Marry a woman like Li Wei.

After transmigrating into Extraordinary Sorcerer, Xiao Ce still had two wishes:

1. Become an extraordinary sorcerer and protect humanity.

2. Marry Li Wei, then train her to become an extraordinary sorcerer too.

Unfortunately, Xiao Ce transmigrates into the body of an average nobody with no talent for sorcery whatsoever.

Fortunately, he has the original book's contents in his head, and he transmigrates exactly one year before the story begins.

At this point in time, Gu Xizhou hasn't become the male lead yet.

In other words, Xiao Ce can seize the opportunities that originally belonged to the male lead ahead of time.

And he succeeds!

When the "Spirit Core" merges with his inner spirit realm, Xiao Ce realizes that his first wish is bound to come true.

As for the second wish, he'll have to put in some work.

Setting

Spirit Core: Spiritual power increases automatically without any training.

Sorcerer ranks: Beginner, Intermediate, Advanced, Grandmaster, Extraordinary

Spirit beast ranks: Beginner, Intermediate, Advanced, Calamity, Taboo

For everything else, see the story.

Many years later, time reaches the end of the original book.

Xiao Ce, now humanity's protector, looks back and suddenly realizes that the final big bad is actually "himself"!
