I am, Flame-Chaser of Previous Era - Chapter 64: "Love"

A man reincarnates in the body of a boy who suffered a tragedy, only to realize that he is in the world of My Hero Academia. What's even stranger is that his quirk seems to have the abilities of Nen and Haki.

As I was writing a brutal review of a popular Nationalistic Superpower Light Novel, I was made to possess a character in it!I then joined an evil organization and was given one mission.To seduce the Heroine.“Oh, that’s not how you should use this power.”As I started to advise the heroines on how to wield their power, things began to go wrong.

Transmigration? A Chong Xi Marriage? Sickly husband? How worse can this get?

Mo Qian Xue now lives in a soddy, destitute, small house with broken furnitures. The grass had grown wild and unruly from lack of proper care. The rice pot in the kitchen, it’s left empty. Well, this mess seemed quite manageable, however, why is it they only have one quilt in the house?

Not only does she serve her husband food and refreshments during the day, does she need to make sure he’s well “fed” at night too?

“It’s getting late now… we should go to bed. Said the sickly husband. She simply closed the door, turned off the lights, and went straight to sleep.

“If you dare move, I’ll kick you out of the bed!” She threatened.

In the end, the man still managed to wrap himself around her no matter how she resisted. The sickly husband wasn’t as weak as he appeared to be!

Mo Qian Xue worked hard to become rich. She built workshops, opened factories, one aided by her sickly husband towards prosperity. Fortunately, she could live a peaceful life far from bickering relatives, but then, much to her dismay, she still had to deal with the villagers knocking on her door.

So they want her money? They want her position as a wife? Since when was she, Mo Xian Que easy to bully?! They want to make her lose face? Alright, let them come a little closer then… give them a…. slap!
