On your wedding night, stay with your godbrother; the Empress is practically throwing herself at you

This book is also known as: [You'll spend your wedding night with your godbrother, and your sister-in-law will spend it with me, okay?]
Wedding night.
The newlywed wife, Liu Ruyan, used the excuse that her father-in-law was sick.
In reality, she was heading to the hotel to meet her godbrother.
Lu Chuan was consumed by rage, but unexpectedly activated the Myth System!
Wait, something seems off about this system?
【Ding】
[Empress Fuyao has been detected near the host. Please immediately kowtow and become her disciple!]
Looking at his sister-in-law, who was only eighteen years old, Lu Chuan fell into deep thought.

[Host has successfully killed the Level 3 Star Beast, the Bloodthirsty Demon Mosquito. Reward: Ten years of cultivation!]
Lu Chuan opened his palm, looked at the mosquito that had been swatted flat when he was in a bad mood, and pondered again.
Ten years of cultivation.
It transformed him from an ordinary good-for-nothing who couldn't cultivate into a seven-star martial artist in a second!
The system may be a bit erratic, but the rewards are really tempting.
When the hotel room door was kicked open, the younger brother, who was only a five-star martial artist, still wanted to fight.
Lu Chuan then realized that the other party was actually the chosen one of destiny?
The chosen one?
I'm targeting the Chosen One.
He slapped his adopted brother away with a backhand slap, then looked at the dumbfounded Liu Ruyan:
"This marriage is definitely over!"
Liu Ruyan: Husband, let me explain. Su Yan is just my adopted brother. We are innocent.
Faced with Liu Ruyan's explanation, Lu Chuan pointed to the bed full of roses.
"Is this also considered innocence?"
Lu Chuan turned around.

[The host crushes the chosen one, gains invincible conviction, and is rewarded with an immortal body.]
Years later, Lu Chuan sat high on a divine throne, with the corpses of countless gods and demons beneath his feet.
His ex-wife, Liu Ruyan, was filled with remorse and begged for forgiveness in tears.
"Honey, I was wrong. Let's remarry!"
The younger sister-in-law, Liu Fuyao, her eyes turned cold as she slowly drew her longsword.
"sister."
"What are you talking about?"
