Gateway of Immortality - Chapter 156: The Fire Crow Array

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?

Good and bad luck has followed Zach ever since he was five. Poor guy. His life has been far from the sweet and peaceful paradise one might expect of the youngest son of one of only four dukes in a great Empire.But a little more excitement than expected doesn't stop him from pursuing his dreams of summoning, and perhaps his luck is finally turning once he manages to summon something great.Armed with maids, a scummy gift of luck, and a strong will, Zach sets out to live life as he pleases, even to the annoyance of those around him. First stop: The Academy.

Having found herself caught in a dispute between two goddesses, follow Olivia as she ends up being transmigrated to a strange new world called Khallasia as another species.

This world contains many different races, from humans to elves and gnomes to beast-kin, along with monsters such as goblins and ogres.

Starting anew in this world with no possessions, she will try to live her life in a world that vilifies the races that make up her species.

Her journey will include having to learn to fight in a world where death is frequent, wars are brewing, and slavery, while illegal, is a common occurrence.

She will face many foes, from wild animals to full-fledged monsters, as well as bandits and robbers to knights and adventures, while she tries to find a place to call home.

With only her appearance changing, her mentality to do good deeds remains the same.

Whether this can continue in this new and more violent world is another story, especially since the urges that plague her species will soon start to plague her.

Warning: This is a harem, yuri novel where the MC is also a futanari.
