Fallout Game Merchant 2.0 - Chapter 36: Powder Gangers go BOOM!

Arakawa Kouki is reincarnated to a Japan with a different history than the Japan he knows with the memories of his previous life still intact. Kouki was discouraged, “Aren’t reincarnation stories supposed to be at some fantasy world filled with swords, magic and elves?!”

Xiao Ran transmigrated to a fantasy world. As a dungeon guard in the Celestial Dungeon, with a special floor called the Purgatory meant for powerful demons and martial arts experts, he faced a huge challenge from the start. The Eldest Princess acquired a forbidden martial arts technique and was banished to the Purgatory. However, no one was powerful enough to restrain her. All the dungeon guards were defeated. Xiao Ran stepped up and declared, “Your Highness, it’s better for you to behave yourself on my territory” and effortlessly subdued the Eldest Princess.

He progressed from imprisoning the Eldest Princess to delivering the Great Xia Kingdom from the evil clutches of various demons and evil martial arts experts.

…

Xiao Ran was the mastermind behind the scenes.

Going against the heavens, Tuoba Ye reincarnated. Body concealing Divine Root, hands holding Divine Talisman, possessing previous life’s experiences, from childhood, began cultivating the most difficult body refining method: Mythical Nine Transformations.

“Do you like me?” “Yes...” “When did it start?” “A long time ago...” “Will you always like me?” “The fireworks...will always be with you...”Looking at her upturned face, the girl's timid hand was gently lifted up. The warmth in her palm has always been so familiar. “Want to go watch the fireworks together?” “Yes.”The summer fireworks blooming in the deep night are just like your touching and tender smile twelve years ago.----------------------------------PS: Youth daily life story, childhood friend single female protagonist.
