Toaru Majutsu no Index: Genesis Testament - Volume 4, Chapter 2: Suspected and Alone – Los_Angeles.

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again. 

The once rich girl Shen Hanxing lost her mother when she was born. She was then dumped overseas by her own father when she was little to her own devices.

Legendary-Rank Blazing Sun Holy Physique Acquired!]He spent all his life caged in a hospital because he was born with something special. Within those thick walls of concrete, he yearned for freedom and love, but he only found freedom in his death.But that wasn't the end.Reborn as Aegon Valeria Augustus, he awakened not one, but two systems.A Sign-In System that rewards him depending on where he is.A 10x Rewards System that multiplies whatever he gains as rewards.One day it’s mythical techniques, the next it’s… bricks. But whether it’s legendary physiques or useless sandals, Aegon takes it all with a grin.Why?He finally had the freedom and love he had always wanted, and along with that came the desire to explore this fantasy world and its culture.But there were a lot of things he missed from Earth, so the system helped him with that too.[Ding! Skill: Master Chef Acquired!][Ding! Skill: Professional Author Acquired!][Ding! Skill: Barista Arts Acquired!][Ding! Skill: Modern Medicine Acquired!][Ding! Skill: Entrepreneur’s Insight Acquired!][Ding! Skill: Musician’s Touch Acquired!][Ding! Skill: Tech Crafter Acquired!]Each reward gave him the knowledge, instincts, and muscle memory of those professions. Suddenly, he could cook dishes no one in this world had ever tasted before, write stories in a style completely alien to their culture, brew strange drinks that hooked nobles with their unfamiliar taste, or even treat injuries with precision no healer had ever displayed.“Who cares about conquering the world when you can explore and enjoy it? Or even help it become something better?”Aegon wasn’t worried about his strength, because his systems were already making him invincible.He only wanted to enjoy the freedom his new life gave him and protect the love he had never experienced before....What to expectVery Slice of Life. Yes, it’s mostly focused on SoL, so if you want tension-filled battles, this isn’t the novel for you.Low stakes.Some drama.Good fights, but low stakes and fun in tone.Light-hearted story.Modern professions introduced in another world.Comedy mixed with character development (which means you need to give some time for MC to develop too before calling out names for him.)Slow paced

“The war is finally over?! Then, what am I going to do with my life?” Caedrel, a man who had spent his entire life fighting, had no idea what to do next. Fortunately, he was offered to become a teacher in the greatest academy in the world. However, he wouldn’t be a normal teacher but a spy for his country’s Emperor! Doesn’t sound too bad, right? Well, it would have been great, that is…until he learned that his class was for the most talented(weird) students in the entire world.
