In the Solarian Empire, people were divided by their blood. The nobles enjoyed their life in wealth, with fine wine and amazing food. They reigned supreme over the commoners. The only reason they were able to do this was that they had knowledge of the most powerful force in the world - magic. The nobles controlled their knowledge from easily going to commoners, making it harder for them to learn magic.

Leo, a young orphan in Solaria, had an incredibly powerful affinity for magic. He didn't even know about it because he could never learn magic- he was too poor to try and learn from any magic academies. He was just trying to survive the streets of Solhaven until he found the lost tome of the Arcane Emperor.

"I can beat a 7th Circle Mage."

"Wow! You must have trained for many decades. How old are you?"

"17."

"..."

The world was going to be turned upside down.

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.

You Liangxing would never open the speech function in game.
That was because his voice was…
Particularly! Kittenish!

But there was one day, he queued up with a teammate who had so much to say that they may as well explode. Vexed to the point of no return, he contributed a voice that was capable of splitting heaven and earth, “Don’t BB.”
The other party who was being scolded stilled. In the ensuing silence, he suddenly let out a long, relishing… Moan.
You Liangxing: “…..”

Later —
He realised that the person was a great god,
Much later,
Without him realising,
He became the great god’s royal healer.
…. And also his boyfriend.
