Naruto: I'm Nine-Tails and My Host is Kushina - Chapter 151 : Changes in the Ninja World

Three years ago, to defeat the Demon God who was trying to destroy this world, thirteen Braves were summoned from another world. Each of them had varied ages and gender. Each of them was bestowed with cheat like powers not normal in this world.

He Yuan had accidentally caused his own death. He had no idea he was even dead until he suddenly woke up on the hard floor of an empty room.

As he tried to get his bearings right, a strange guy suddenly popped out of thin air and he was offered a job.

The job offer granted him eternal life with the alternative being reincarnation. Most would hastily choose to be reincarnated so they can start a new life but not He Yuan.

He was skeptical, why would anyone want reincarnation? Once you reincarnated 'you' cease to exist. He didn't care about what people said about starting afresh, gaining new memories and all that.

All he knew was that once a person reincarnated, they get thrown into a different environment, different family, meet new people and in short became a different person entirely.

What scared He Yuan the most was losing his own thoughts and hence, awareness of his current self and so, he chose to accept the job.

What did the job entail? He carried out tasks given to him by people who were called 'leasers.' They were called this because they leased out their bodies to 'taskers' for a period of time to help set their crooked lives straight.

What the leasers didn't know was that the taskers got into realms and helped them so they( taskers) could focus on their own main tasks which was world/realm balance.

These realms had 'special ones' who siphoned the luck out of it. Luck was the binding force of these realms so without it, the realms would begin to break apart and deteriorate into unlivable hells.

So in essence, leasers gave put their bodies and 'payment' in the form of soul energy, taskers helped out the leasers while balancing the realms and the realms become stable once more.

Pretty straightforward right? Yes.

But can someone tell He Yuan why these world was so full of hypocrites, Mary sue and Gary stu characters who thought it was excusable to do horrible things just because they were in love?

He Yuan grit his teeth. If you want to be in love, then be in love, was there any need to use others as stepping stones?!

He rolled up his sleeves and bounced forward. Just you wait as I teach you all a valuable lesson!

On her wedding day, she was humiliated; her status as the legitimate wife was instantly changed into that of a concubine.

“wh***! Marrying you is my life’s shame!” These were the hurtful words that came from her childhood sweetheart, now husband.

….

Jiejie, jiejie, thank you for your sacrifice. Jiejie, if you’re kind then go. Meimei will replace you and take good care of your husband, to help you enjoy the blessings that you are unable to enjoy!” these words spat out by her smiling cousin made her whole body feel cold.

….

“You are shameless! There is no need to say anything! From now on, our Shen family will not have you as our daughter! Someone! Throw out this shameless woman!” These were her relatives?

…

Becoming the target of criticisms, and being submerged in a small lake, she realized that all of this was the result of another person’s scheme – but it was already too late!

…

Instead of dying, she went back to the past, back to where both feelings were still alive and were loving towards each other; back to when she was not yet an orphan but the doted on Di daughter of the Shen family.

No matter what, in this life, she would never allow anyone to hurt the people she loved. And those people who harmed her in the previous life, she would make them pay the price!
