MTL - Great Slaughter System - v2 Chapter 708 Self-destruct

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

After being hit by a flower pot, Yu Wan woke up as a poor village girl with an unconscious and fragile mother and a little brother.

She was lost as she did not know this unknown ancient world. But she had to pull herself together, because her mother is still unconscious and her brother was starving.

So she plowed and sowed until she had a large piece of fertile land, rising to the peak of success ever since.

Just as life was getting comfortable, a man, widely feared and rumored to be a living Satan, forced his way through her door, declaring he would marry her!

Although she adored beautiful men, it was rumored that this prince…

“Your Grace, we don’t know each other well!” She said seriously.

“Heh!” The prince smiled meaningfully before grabbing three little toddlers with chubby cheeks from behind of him. “Greet your mother.”

Yu Wan was flabbergasted…

After being reborn in a sci-fi ABO world, Xi Wei became the newly born son of the Imperial King. He thought, as the emperor’s son he could live a carefree and imposing life, but unexpectedly the First Prince is actually an omega? What the hell is an Omega?
