MTL - Orc Empire [Future Beast World] - Chapter 29 holiday

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

The world was destroyed, torn to shreds by the war as it raged on. With the falling of nuclear bombs, the mutation strangely adapted and became an entirely new element.Those who couldn't withstand this mutation became beings tethering on the edge of life and death, becoming undead.Only a small population remains on the earth now.In this small population, some can adapt to the mutation and awaken unique powers in the apocalypse, while others are entirely unaffected, still like normal people.Ray was just a normal E-class awakener, but a faithful purple crystal changed everything.Through the purple crystal, a “system” activated inside him, which could allow him to get stronger the more he spreads his genes.Necromancer, wizard, martial artist to sorcerer - every single skill was possible as long as he spread his genes.From that moment, Ray walked the path of spreading his genes “for the sake of humanity.”#no ntr, yaoi or yuri

Twenty years ago, she was taken in as the Lin family’s young heiress through a twist of fate. But mistakes would eventually be corrected one day. When the real daughter of the family returned and her foster parents begged her to stay, she obliged. Unbeknownst to her, this was actually a scheme disguised as familial affection. They only kept her around to squeeze her dry of all her value!

Seria, a social outcast, has changed.
Seria Stern, the wicked woman who made everyone tremble with fear, was now calm.

In fact, she wasn’t just changed, she was a completely different person.

The moment she realized that she had possessed the body of the villain Seria, in a romance novel, she had a hunch about the future and decided to live low.

She would avoid kidnapping and harassing the original heroine, hence preventing her death by decapitation at the hands of Kalis, the second male lead.

In order to avoid that, she had to fix her bad relationship with Kalis and even healed his injured arm.

Thanks to that she got engaged with him, so it’s all worked out.
Finally, the original heroine returned, and her husband, Lesche, should be on good terms with her now.

“I’ve been waiting to escort her, so…”

Lesche asked, resolutely cutting off Kalis’ words.

“Miss Seria, it would be better for you to choose. With whom would you want to go with?”

Something was strange.
The original, wasn’t it perfectly fine?
