Herald of Steel - Chapter 1496: Meeting Vidiyan Again (Part-End)

The story is about a boy entering high school, who answers a strange call from a public phone one night. The caller challenges him to a bet: She’ll remove the birthmark which he sees as the cause of so many problems, and he’ll have fifty days to win the heart of a girl he’d considered far beyond his reach. And with this, a very strange summer begins.

When the system warned the world that it was coming a week in advance, Alex couldn’t have been more excited. In college for a degree he didn’t care about to get a job he didn’t want, the promise of a world where magic and challenge awaited — even at the potential cost of death — was the best news he possibly could have imagined. Alex was ready for a new life. He ready for his only friend to shove him through a portal into hell the moment the apocalypse started. Instead of getting to punt rabbits and farm wolves, Alex finds himself stranded in a warped world where even the bugs are stronger than he is. Even with a summoner class that gains the powers of its monsters, most people would have died. Alex didn’t get the memo. He might have liked challenge a little bit too much. Where others saw certain death, he found something else. Opportunity.

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 not yet met Jiang Yu: Oh, it’s a small star who wants to hug my thighs.

The after contact Jiang Yu: Really fragrant.
