An Extra's Rise in an Eroge - Chapter 170: Footjob***

Fu Qian gracefully removed his skull, as if a gentleman were taking off his hat to pay respects.…Everything began with a transcended-dimension invitation.It’s a story of a high-quality Thug turning the impossible into the possible.Of course, on that day, the great being behind the invitation was still unaware of what it had done.

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?

Ren Zhouyuan, who loves to study Chinese culture since childhood, has never imagined that his own life would one day be subverted by a foreigner.

Not only do these foreign devils not love the Chinese, but they also scoff at him, looking at his eyes like watching a fool.

After getting drunk, Ren Zhouyuan is for no reason pregnant with a ball, and actually gave birth to a child as a man. This kid is blonde; almost do not have to verify who he is from the “handwriting.”

Ren Zhouyuan does not want to make that arrogant foreigner part of his life, but after fate tied them tightly together again, he found that there was a big difference between this man and the arrogant fighting nationality he imagined.

Leonid: Honey, what does ” Jijiwai Wai*” mean?
Ren Zhouyuan: Refers to people like you
Leonid: But I’m not chirping ah …

- Description from Novelupdates

A man was about to commit suicide and decided to search for a way to die on the internet, but then he found an odd site that asked a lot of questions and had a point based system that allows you to create skills for a character. He took interest in it, and when he was done setting his character, he was asked, “You will now be transported to a world with the settings you chose. Coming back is not possible. Do you still accept?” Without thinking much of it, he pressed YES and found himself in another world with the skills he chose to have.
