Dark Warlock in the Apocalypse - Chapter 104 Expansion II

I reincarnated as Luna, a supporting character who is accused of ruining the heroine and hero’s relationship, and is mu*dered. I’m not interested in someone else’s man, but the heroine’s friends bully me every day. “Why are you trying to get close to someone who’s already taken?” “That’s right, please stop! Why are you doing this?” “Stop doing such terrible things!” So Luna decides to announce it in front of everyone. “I don’t want someone like Fersen even if you beg me to take him so stop bothering me. I’d rather date Anthes Vincent, who’s rumored to be insane.” And soon she meets someone who she never expected to meet…… “I heard you have an interest in me? The truth is, I do too. Is it a coincidence?”

Kuramoto Daisuke, a freshman in High School was suddenly exposed to someone vanishing in front of him. Turns out he was admitted to a Special Class full of Isekai Heroes that were regularly summoned to Otherworlds since the start of their Middle School. He was told that he was to become their Support to prevent each of the Heroes' fate of dying in the world they were summoned into. Though mediocre, he realized that his ability has a great potential but it needs a lot of hard work on his part.

Unconvinced of being just the Support Character, he vowed to excavate his mediocre ability, all the while supporting the Heroes using it.

And maybe more.

A detective travels across the United States and becomes an agent of the Los Angeles Police Department.

[space + ancient times kingdom building + escaping from famine]

The big shot from the future, Bai Wutong, transmigrated to ancient times with her space pocket! Before she could feel happy, she found herself in a chaotic world! There was murder, robbery, schemes, sky-high prices, and many other things happening all around! The moment she arrived, she had killed two people. Then, she also kindly saved someone, but was deceived and stalked as the person insisted on following her. If that’s the case, then don’t blame her for using aggression in return!

After she finally managed to settle down, she was assigned to the frontier to develop the lands. The remote lands were out of anybody’s control, and there was nothing more that Bai Wutong could ask for. After a few years, Bai Wutong accidentally led the richest man of the previous dynasty, the prime minister, the commander of the secret guards, a great scholar of the dynasty, the holy maiden, as well as the divine doctor… and turned the barren land into a rich, noble town that everyone desired. When the emperor and his ministers came to admire the place, they were dumbfounded. That man who was pouring tea beside Bai Wutong… Wasn’t that the eldest son of the previous emperor, who had been dead for many years?!
