Magika no Kenshi to Shoukan Maou - 3.1.1 — The Night of Beginning

Li Ran traversed to another world and became the Holy Son of a Demon Way Sect.

The system has awakened, and the first task released is actually to fall in love?

The Sect strictly forbids relationships between men and women.

Li Ran took the risk of being expelled from the Sect and wrote a love letter to his junior sister, but it was sent to the master by mistake!

Having a rough life growing up, Wang Tong had numerous dreams of living a better life. However, his alcoholic foster father sells him off as a space settler of the distant planet Norton for some pocket change. Soon after his arrival, the Zergs overran the planet and obliterated its defenses in a matter of minutes. What awaited Tong on Norton was more than just an unbearable environment – its gravity alone was five-times stronger than earth – there were also swarms of bugs, constant hunger, thirst, and desolation.

While he lives a year of total carnage and survival, humanity’s Confederation eventually overcomes the Zergs on Norton and the powerful survivor Wang Tong is given a recommendation to a once famous, but now dying military academy where he begins his life anew.

Penny has three brothers: one is a billionaire CEO, the second is the youngest military lieutenant, and the last is a successful actor.These three successful men had only one common ground: bullying Penny, their sore-eye of a little sister. The sister they never wished to have, and the one who claimed to be their real sister, while the sister they treasured all this time was a fake.After living a life of maltreatment in her aunt's home, some people of high standing came to Penny with news of her real parentage. She thought she was finally saved from her aunt’s clutches, unaware that what awaited her was worse.At 13, Penny only wished for one thing: for her brothers to love her and treat her like family, just as much as they loved their fake sister. She worked and studied ten times harder than anybody else just to be accepted by them. In her desperation, she foolishly fell into a trap set by a malicious person, not knowing her actions would result in the downfall of her brothers and her ending up in jail with a death sentence.On her execution day, Penny had only one thought in mind:If she ever got to go back in time, her brothers could pamper their fake sister for all she cared! She wanted nothing to do with them! And much to her surprise, Penny found herself back on the day it all began: the day she was born.As promised, this time, she wouldn’t foolishly try to earn her brothers' love and affection. Never mind family! She’d just make a lot of money, live in luxury, and make a family of her own!But wait, why is it now that she didn’t want anything to do with her brothers, they kept poking their noses into her business? Weren’t they supposed to pamper their fake sister? Why won’t they leave her alone?!And how on earth was she married in this lifetime? To make matters worse, this husband she never had in her first life was suddenly volunteering to be the father of her children?!
