As a Magnate, I Started Checking in at a Convenience Store - Chapter 727 - : Is This a Sun Tzu Strategy? No, I’m Doing It for His Own Good (2)

Amakawa Haruto died before he’d the chance to reunite with his childhood friend who disappeared five years ago. Rio, a young boy living in the slums seeks revenge for his mother who was murdered in cold blood in front of him when he was only five years of age.

There exists the earth many knows of and there exists an alternate world. Two people, each with their own backgrounds and values. For odd reasons, the memories and personality of Haruto, one who should have died resurrects in Rio’s body. As the two are confused over their memories and personality fusing together, Rio (Haruto) decides to live in this new world.

Along with Haruto’s memories, Rio awakens an unknown but special power. If he’s to use it, it looks as if he can live a better life, but before that, Rio encountered a kidnapping which results in involving the two princesses of the Bertam Kingdom.

After saving the princesses, Rio is given a scholarship to attend the Royal Academy, a school for the rich and powerful. His background being a poor orphan who once lived in the slums, the school full of nobles was rather a detestable place to stay at.

After dying in an oddly anticlimactic vending machine accident, Kazuki Ren is reincarnated in the demon realm—not as a hero, not as a villain, but as the only human male student enrolled at the mysterious Academy of Ruin, a school where all the professors are demon lords and all the students are powerful, beautiful she-demons.Ren is told he has one task: survive.But there’s a catch. The Academy’s darkest secret is about to awaken, and Ren holds a hidden power that could either destroy the demon world... or rule it.Now surrounded by seductive demons with hidden motives, eldritch tomes, forbidden dungeons, and twisted exams, Ren must master his ability—or be consumed.Magic, mystery, danger, and temptation await in this dark academia harem fantasy.

She was stupidly in love with him. Because of him, she became rude and unreasonable, overbearing, jealous, insane. But he did not spare a glance to her. Married for two years, he didn’t favor her once, letting her become the laughing stock of the whole world. Eventually, she ended up in an affair, leading to her tragic death.

When her eyes opened again, it was a different person.

Since it’s an empress, then we absolutely must be virtuous, generous, correct the previous jealousy defect.

Thus begins the replacement empress’ harem life.

Taking the initiative to help the emperor look for beauties, sending them to serve in the bedroom, teaching the imperial concubines how to primp themselves to win the emperor’s favor, and even using the phoenix seal as a reward. Whoever can satisfy the emperor on the dragon bed, will have the opportunity to take the phoenix seal and sit on the phoenix seat, to experience the feeling of being the empress. Being this virtuous can really be called impeccable.

She was this virtuous, the emperor ought to be pleased in every aspect!

Hadn’t expected the emperor wouldn’t know good from bad. Not only reprimanded her, but also contradicted her everywhere. The beauties she’d sent were actually all driven away.

Since he didn’t like the beauties, apparently there’s a special interest. In that case, send over a group of beautiful men. Can top, can bottom, every option is there.

In the end, they were also driven away.

Thus the empress personally arrived to battle at the emperor’s bedroom-

“Your Majesty, do you have an unmentionable illness down there? If so, rest assured and tell me. I’ll let some people treat it in secret.” Take a look at her virtue, she could move herself to tears.

“Unmentionable illness?” The emperor’s sword-like eyebrows raised, the eyes suddenly looked dangerous. Approaching her slowly, unexpectedly ordered: “Tonight, the empress will serve me.”

“What?” Then, Mo Qiqi with lightning speed jabbed the hornet’s nest.

“Ah!” A miserable scream.

Mo Qiqi worriedly looked at the emperor to inquire: “Your Majesty. Are you alright!”

The emperor spoke with a pained expression: “Call the court physician!”

“You did have an unmentionable illness!”
