On earth, Felix is just a normal guy, a bit of a loner but otherwise normal. In the multiverse, under the rule of The System, he's a caster. Fascinated by magic and hungry to learn, grow and discover, this series follows Felix on his adventures through the integration and beyond.

In his past life, the beta Su Liang dared to seduce Lu Zhizhao, the future of the Lu family, and eloped.

In the end, after burning down all his boats with no hesitation, Su Liang realized that he was nothing but a big joke.

Su Liang gave up everything, and died silently on the day after Lu Zhizhao’s marriage to someone else.

Reliving a life, the courageous fool of that year finally learned to accept his fate.

This time, Su Liang honestly accepted that he was an unfavoured and mediocre beta, feeling that this bland and undemanding life was quite good.

After all, the way of the salted fish is the best way.

But after just a few peaceful days, he was sent into the forbidden area, in the depths of the noble’s compound.

Lu Taipan – who used to be a big boss, is now a big boss, who will always be the kind of sinister and ruthless big boss who would make everyone tremble with fear when he comes out.

However, it was this top-level alpha who single-handedly supported the Lu Family, but suffered from pheromone disorder.

And, the place where he rested, was a forbidden place in the eyes of everyone.

No matter how many things Su Liang thought about, he didn’t expect Lu Taipan to embrace him in the frenzy of his pheromone disorder.

Then, he bit the back of his neck with a single bite.

“Your pheromones…. smells good.”

The devil-like man, like a beast, scented the pheromones on his body, and muttered greedily.

Su Liang was horrified to discover that Lu Taipan and him became more and more intimate. He, who was supposed to be a beta, somehow began to develop unusual pheromone glands.

From a beta, he was now an omega.

Moreover, he was an omega who matched perfectly with Lu Taipan.
