Orion was on his way back home from work.He was hurrying back home to take a nap while planning how he would spend his weekend as well, but while he was lost in thought, a truck suddenly appeared out of nowhere and the last thing he remembered was the truck barreling towards him before everything around him turned dark.However to his surprise, he didn’t feel any pain after having the accident. In fact, he couldn’t see anything.Everything around him seemed dark but when he opened his mouth to speak, he heard the gurgling sounds of a baby.Noticing that the one sounding like a baby was him, Orion tried to open his eyes to know exactly where he was, but when he did, the first thing his eyes fell upon was a stunning beautiful elf, holding him with the most tenderest of care.Not only was she his mother, she was also a queen as well and she had a beautiful sister who adored him just as much as his mother.Aside from this, Orion also noticed he had received a system which allowed him to grow and evolve faster than a normal High Elf but after finding out the huge role his mother played in eradicating the war between all races, Orion vowed to live a happy and fulfilling life with his mother, aunt and a few others he cared a lot about.

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!

The world that nurtured the civilization which reached the pinnacle of magic was on the verge of destruction.
