Gathering Wives with a System - Chapter 20: Genetic Catalyst

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Why is it “Hero” that “Savior” that? Why is it always the same happy ending? “Happy” “Good” “Perfect” endings? You know what? SCREW IT. I will give you all the worst possible ending possible? Why? Because I’m an asshole!

While watching an action movie, Ye Xuan suddenly died and came to the mutated Blue Star.However, he became a person with the lowest awakened attribute, a total loser in the eyes of others...“Ding! Congratulations to the host for successfully binding the invincible beast control system. The novice gift package has been automatically delivered!”“Ding! Congratulations to the host for obtaining the SSS-level spiritual attribute, with an affinity for all beasts!”Ye Xuan's body trembled suddenly.Did he just receive some powerful cheats?It was awesome!The genius campus belle said, “Is this the loser you guys were talking about? His beast is so big!”The mature mentor said, “Ye Xuan, controlling beasts starts with controlling people. Come to my room tonight and I'll teach you hands-on!”The ice-cold empress said, “God, he's too strong. He's the man I've been looking for!”A beautiful witch brought chaos to the Blue Star with evil magical creatures.Ye Xuan said, “Don't worry. I'll take care of it!”

I was left paralyzed with only a month to live, but that “9-inch” part of me was still hard as a rock. Even the sickly beautiful schoolgirl couldn't resist my “pecker,” and to fulfill my dying wish, my sister even dressed up as a lady in black stockings to teach me how to “drill.” What's more outrageous, the hospital nurses wanted to make a little movie with me, lining up with the head nurse at the front...Just after coming out of the emergency room, I saw the system panel:Name: Ethan JonesGender: MaleLength: 9 inchesSkill: Hard as a Rock LV1Note: Peak human hardnessDying Wish: To caress auntie's sheer black stockingsTask Reward Points: 1000 pointsDespite my strength and stamina attributes being only at 1, and my agility at 0, only my “pecker” could lift the heavy blanket while doing squats. My face was full of question marks—what kind of bug is this system? Just because I like looking at auntie's legs, did it give me such a special skill?Now, I have no choice. I must complete tasks to earn points and add attribute points.However, the story actually begins 12 hours earlier...
