Seria, a social outcast, has changed.
Seria Stern, the wicked woman who made everyone tremble with fear, was now calm.

In fact, she wasn’t just changed, she was a completely different person.

The moment she realized that she had possessed the body of the villain Seria, in a romance novel, she had a hunch about the future and decided to live low.

She would avoid kidnapping and harassing the original heroine, hence preventing her death by decapitation at the hands of Kalis, the second male lead.

In order to avoid that, she had to fix her bad relationship with Kalis and even healed his injured arm.

Thanks to that she got engaged with him, so it’s all worked out.
Finally, the original heroine returned, and her husband, Lesche, should be on good terms with her now.

“I’ve been waiting to escort her, so…”

Lesche asked, resolutely cutting off Kalis’ words.

“Miss Seria, it would be better for you to choose. With whom would you want to go with?”

Something was strange.
The original, wasn’t it perfectly fine?

Programmer Li Daochong desperately develops the game code, dying. After waking up, being born again in a ghost-invading future comprehension world, isn’t that a pothole?

However, Li Daochong brought his own ghost upgrade system, which made my green onion. Others are devilish and scared, and they rush to hell. Hey, isn’t this the tip of China? I want to eat, drool!

Eating is not the most important thing. The key can be upgraded. How many levels does it take to finish?
　　
“Li Daoyou please stay, people want to go to the edge of the magic field on the edge of the magic field, can you accompany others? People are afraid!” Hongyang fairy is dripping at Li Daochong.

“Li predecessor, can you please go with a younger generation to go to a ghost dragon?” A white-haired girl who is more than two hundred years old can look at Li Daochong helplessly.
