After Fishing For 10 Years, I Became A Saint Without Knowing How To Raise Beasts - Chapter 468 - Two Wives

Rainer, an amateur arcanist and college student, sought to create a new spell far surpassing the magic of the few he inherited from his grandfather. Yet the interference of an unknown event during the casting of his spell led him to be thrown through space and time.

Yuan Luoyi felt like she was a little hamster in a pit of snakes, with her family full of crazy villains, yet as the fake heiress she still focused on slacking off.

Dad was an arms dealer, Mom an ace assassin.

Eldest brother, business world’s killing god, with proxy syndrome.

Second brother, cold-blooded lawyer, zero moral sense.

Third brother, addicted to killing, born with antisocial personality.

Fourth brother, evil celebrity, who trained fans into believers.

Fifth brother, genius scholar, loves those pure white bones.

Yuan Luoyi didn’t know that because of her birth, the world gained five more brothers, not five more lunatics.

Those greedy villains also didn’t know, the one they wanted to kill was not an ordinary girl, but the most beloved little sister of five crazy bastard brothers.

The female lead has 99 lifetimes of memories, a system, harem darling + suspense, happy ending.

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?

To take a dragon's hoard is to challenge death.The greatest of the sea-drakes wakes, curled on his silver throne; but there is no silver. His hoard is stolen. He rises, screaming, and chases the thief to the ends of the world—only to be shot from the sky.But dragons do not die easy, and never one with such festering hatred. A dungeon core rises from his corpse.If he intends to survive so near the cove of pirates that slew his past self, he'll need to master his powers—and quickly. For these pirates are dragonslayers; they won't be felled by mere mushrooms or spiders.Beneath the lawless Calarata, the young dungeon core will have to fight to survive; and one day, he will return death to the man who killed him.
