Seth spent the entire night pleasuring Jiang Yi and himself in a multitude of different forms. Actually, he prioritized his own pleasure, but it ended up making Jiang Yi feel even better, since he was going rough and hard at it, what made her love it even more.
When morning finally arrived, Seth was feeling refreshened. As a Mana Control peak-stage Realm cultivator, his stamina was already thousand times greater than a normal person's stamina; on top of that, Seth's body was modified once by the Seed of Tyranny and later on by when it turned into that Crimson Light, making him practically an unstoppable machine.
Unfortunately for Jiang Yi, she wasn't able to accompany Seth till the end, almost fainting from exhaustion. At least, she had a very happy expression while she was sleep.
He got out of the room, leaving the unconscious Jiang Yi behind. He expected that she would be gone when he arrives later at night.
