I, the Villain, Want to Save Myself, But the Yandere Heroines Disagree - Chapter 12 - Changing Opinions

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?

Human civilization expanded into space, and its territory spanned across galaxies.

During this great trend of interstellar migration, Zhou Qing accidentally awakened the power of traveling to various Astral Realms. He was able to create [Astral Realm Apostles] as vessels for his soul and project them onto different realms. This allowed him to travel through various worlds with different identities.

His unremarkable life was met with an unexpected twist of fate. Every time he created a new Apostle, it was like being reborn.

Yet, slowly, he realized that the Human civilization wasn’t completely ignorant about the existence of other realms…

——

Multiple-dimensional worlds, multi-dimensional factions. This is an clash of fate between realms!

And he is the only being who is able to travel amongst the realms in countless different shapes and forms — The Astral Apostle!

I am the master of a certain dark guild.

Including me, there are only 10 other consistent members in this guild. However, all of them are like daughters to me… is what I think.

Since this is a dark guild, we act without standing out too much. However, it seems like everyone has been acting a bit too weird recently.

They’re acting really weird… eh? What? [Presenting me the whole world]?
