Standing Next To You - Chapter 438: Invitation for the Royal Banquet

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?

PS. Cover not mine, I just found it on google.

Kyle woke up in a land of fantasy and magitech. The usual 'I died and woke up' bullshit, skip all that.

Except he used to be a crime lord, and society here is missing that extra kick.

The five different worlds of demons, demons, ghosts, monsters, and beasts descended on Blue Star in the form of dungeons.

Human beings will be randomly selected by the Heavenly Dao system and enter the dungeon in another world.

Su Qianqian, a cute baby in the senior class, was accidentally selected.

When Su Yang learned that her daughter was going to enter a dungeon in another world, she told her: “Don’t play for too long, and go home on time for dinner.”

Play? Do you think that the purgatory alien dungeon is a playground?

Just when the whole world thought that Su Qianqian was going to end, they were surprised to find that she really came to play.

In various dungeons of other worlds, the divine beast Qilin serves as her mount, a generation of demons kneel down and beg to be her full-time nanny, giant giants of the sky serve as her thugs, and the flower demon fairy goes too far, wanting to be her stepmother.

The whole world was shocked. Who is Su Qianqian’s father, Su Yang? ! !
