Naruto: Reborn as Neji Hyuga After Dying in One Piece - Chapter 3. Restoration

Eren Idril died as an old, decrepit, and piss-poor adventurer by the maws of a D-Rank monster. He had a lot of unfulfilled dreams and desires that couldn't see the light of the day after the light in his own eyes died down.

But fortunately for him and unfortunately for the world, that wasn't his end. Eren was somehow dived back in time when he was a mere teen, attending Lionheart Academy for adventurers.

When life gives him a second chance, Eren decides to exploit it to its fullest. Experience his vile deeds as he partakes in them without feeling the slightest bit of hesitation.

After an unfair life and death, Qin Hua was miraculously gifted with a second chance. But she was a dog now? And the world suddenly changed?

Terrifying beasts roamed the streets instead of cars and trucks. Plants turned deadly. Rifts to other realms opened in random street corners and more importantly, humans gained unimaginable abilities!

Earth entered a new beginning where mana was abundant and one's monetary wealth no longer determined their fate!

With the strong surviving and the weak perishing, will Qin Hua kill or be killed in this new world?

This is a story of the earth's spiritual awakening and a dog's rise to power!

Every novel has a slag character, the one who decides to abandon the protagonist at his lowest, most helpless point, either because he can’t stand the poor guy’s circumstances or for other reasons. But after the protagonist wins his way in life again, they’re the ones who beg with broken sobs to be taken back.

Still, water once spilled can’t be recovered again.

Yet the unlucky Shen Jiayan has been bound to a Water Recovery* System to do just that.

*water recovery – comes from an idiom that means “spilled water can’t be recovered” (English equivalent: there’s no use crying over spilt milk).
