When the Doctor Uses A Hack - Chapter 28 - : The Dragon of Mona Lisa

One morning, after being bound to the system, MC started his routine of always being captured/ attacked by the ML.

It doesn’t matter if he transmigrated into the ML’s little brother (TN: Here I think brother disciple) or master or opponent, but in the end he is still forcibly taken by the ML.

After transmigrating to many worlds:

MC: Come out system!!! The heck?! Why do these MLs not love their female goddesses, but insist on doing it with me! Aaaaahh!!!

System: …. __(:3」∠)_ Don’t ask me, I also don’t know.

From the outside, Nana’s life seemed simple. She had everything she had ever wanted: a cute but rascally pair of twin brothers, a best friend, and her own restaurant. Nana couldn’t ask for anything more; she was happy and content in her life.

During the day, she was his secretary, working very hard with excellent abilities. At night, she was his bedmate, trying her best to please him, and the two of them were very harmonious in bed. One day, this relationship was on the verge of ending. However, both of them had already become deeply involved and had grown accustomed to each other's presence, falling in love with each other. So...

He died in his first life, as an ordinary human inside an ordinary planet.

In his second life, he swore to live a life of supreme power, and so he did. He reached the apex and exterminated his enemies to oblivion.

Dying, he was reincarnated in a world which could use Chakra. He became The Overlord Of Every Being, Ruler Of 6 Universe.

Unfortunately, he died. Using a mysterious method, he was reincarnated once again inside the world of Tales of Demons and Gods.
