Ways to handle this little demon

For him, this world is the very definition of cruelty and hell, an existence that should be utterly devastated and wiped out once and for all. If he couldn't have peace, then no one was allowed to have it, just as his whole life was an absolute nightmare, each and every life of these humans had to be eternal nightmare. Demon King, Zhang Long wei, spent his whole life holding onto this so-called the world's most reasonable logic of his.

To the whole cultivational world, he was such a great calamity that was impossible and unimaginable to annihilate, the very fear of every single being.

But then, the news of the great Demon King getting slain by a group of young cultivators made the three realms ended up in uproar.

Everyone was gloating and celebrating for his decease when Zhang Long wei found himself waking up in a body of a fifteen-year-old boy named Li Zian, a disciple of the immortal Wang. And there, what intrigued him the most was that the person who was responsible for his downfall, the one who took his life and also the leader of that youths' group, had turned out to be that one and only genius son of the immortal Wang, the shizun of his current body.

What would be the first thing that came out of his mind? Revenge? Nope.

His life had been all about these kinds of malicious stuff, so he decided to enjoy this one with the life of a regular youth. Let give himself a try to be average and normal. Let give the world some time for peace.

Nevertheless, after a couple of confrontations with that son of his present shizun, his iron- like heart was melted and fell for this unruly youth somehow. The demon king started to chase after him with the mask of his aged fifteen body.

Even so, heaven was too vicious and parsimonious to let him adore these blessing moments for a longer while as the fate between him and the youth was reversed. He had become people's hero whom the youth once wished him to be, yet the youth was now converted into a demon who had gone crazy for a brutal fate his family and sect had encountered.

Let's see how the once powerful demon King would handle and tame this little demon and how these two would work together to find out and exterminate the real culprit behind the scenes
