In Naruto with the Flame-Flame Fruit - Chapter 46: - : Victory

I came from hell, looking for redemption! –“Revelation”
…………
What is redemption?
I think it should be a process in which a good person becomes bad and then becomes good again.
It’s like our clean birth, contaminated by the dust of one life, and then clean death.
Well, this is just a story. …

They appeared in all major cities on the planet infecting millions by the day.Among them was Adrian, a college student who was about to go home after his class when suddenly zombies appeared out of nowhere. Of course like every human being who sensed danger, he ran and escaped. But minutes after he killed a zombie, an holographic interface appeared.[Modern Weapons Gacha activated!][Would you like to try out your luck in a modern weapon gacha system?]Adrian tested it since there’s nothing to lose.[Congratulations!

Even a tank or an attack helicopter!With his new power, he would use it to kill zombies and hostile survivors, and save the people who were dear to him.And just like that, Adrian suddenly has a weapon to fight in a new apocalyptic world.

Chen Lu Si finds a strange stone and meets a strange girl during his tomb sweeping.After the girl slashes him with a sword, he finds that he couldn't control his whole body but his mouth, and his hands are turning into swords.“I have no objections to the rest, but I think the danger sequence should be upgraded to A. His Transforming Blade ability is too dangerous for ordinary people... And I don't think recruiting him into Celestial Strategy is a good idea.”“C, you saw it earlier; his arm got dislocated cutting a bullet. Although it can barely handle modern weapons, it's uncertain against fully automatic weapons.”
