The Laws of Cultivation: Qi = MC^2 - Chapter 9: Experiments

Ye Xuan transmigrated back to when he was an infant cuddling in the embraces of his nine older sisters. He activated the God-tier Sign-in System.

[You are hugged by your eldest sister, who is the COO of a financial conglomerate. You signed in and obtained RMB100000000.]

[You are fed medicine by your second sister, who is crowned the God Hand. You signed in and acquired god-tier acupuncture skills.]

[You trained along with your third sister, who is a Martial Arts Grandmaster. You signed in and your overall physique improved.]

[You live-streamed with your fourth sister, who is the top news anchor in the country. You signed in and acquired extraordinary good looks.]

……

Ye Xuan could sign in daily!

After staying in the city and signing in for eight years, Ye Xuan had accumulated an astronomical amount of wealth and become a billionaire.

On his eighth birthday, his nine sisters were forced by the grand elder of their clan to get married. Just when everyone had lost hope of turning things around, Ye Xuan hopped down from his eldest sister’s embrace and said, “You’re marrying my sisters off against their wills. Have you consulted me about this?”

「Shimizu-san, you dyed your hair black.」「Ah, yes.」「Why did you dye it all of a sudden?」「Because…yesterday…」Shimizu-san, who sat next to me and had dyed her hair from blonde to black gradually lowered her voice, slightly blushed, and laid her face down on the desk.

“My dad just married the Queen of Hell… and now she’s cooking me breakfast in a bathrobe.”Kazuki Sakamoto was your average awkward university student—until his father remarried a stunning woman from a mysterious dating site. Now, he’s living with Lilith: a dangerously seductive, battle-hardened demon queen trying (and failing) to blend into modern Japanese suburbia.She torches toasters for fun. Summons eyeball familiars to spy on him at school. Wears his dad’s shirts like she owns the place (because she kinda does). And worst of all? She’s disturbingly good at playing the “loving stepmom” role… with a wink that says she knows exactly what she’s doing.Caught between sanity, seduction, and spontaneous hellfire, Kazuki must survive:• A stepmother who flirts like a villainess with a mission• A house full of demonic chaos• And the terrifying possibility that he’s starting to like it⸻A romantic comedy harem full of magic, mischief, misunderstandings—and one very dangerous MILF.If you like seductive demon queens, chaotic slice-of-life, and nonstop supernatural comedy, this is your next obsession.

In the end, war couldn’t be extinguished. But, there was a transformation. Even in the heart of a worthless accomplice in murder who was indifferently continuing his task, there was a transformation. The massive weapon “Object”.

This was a weapon that changed the whole definition of war. An exchange student named Quenser, who was dispatched to the battlefield, met at the base a girl with a strange aura. The girl, dubbed “Elite”, is the pilot of “Object”. The near future. This diminutive boy had come to take on the role of standing up against the strongest weapon “Object” for the sake of the girl. This was the motive for their first meeting.
