Mr. CEO Wants to Renew Our Contract - Chapter 11 - : None of Your Business

Did I just get reincarnated to the old self and the old world? What the hell kind of reincarnation is this? And that too no system? Fine. I guess I will do things this time differently. But wait what is these two white bulbs inside my head that I can even internally see. Is that the system? Nope. It's better than I thought. Follow Aric has he gets access to two different universes, one based on magic and other based on technology. Now he can teleport to two different universes whenever he wishes. Hopping around seems fun!What to expect : * 1000 words per chapter at least with 4 5 chapters per week * No harem* Don't expect MC to be a genocidal maniac but he will be ambitious.

This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.

Reborn into an ancient world of hardship, Chen Qing became a scholar who toiled through ten years of cold study, finally achieving fame on the golden list. Just when he thought he'd join the ranks of the literati, marry a beauty, and reach the pinnacle of life, he suddenly found himself entangled in a bizarre and fantastical incident.It was also at that time that he discovered this world was far from simple—there were man-eating demons, heart-bewitching devils, and even the legendary immortals who could live forever but were exceptionally strange!What he found even more inconceivable was... these deadly things seemed... to all have been designed by himself!!!

To save a doomed fantasy world, I killed the main characters, then destroyed the game world, and fell into another timeline as the academy's top seat and rival to the protagonist.Now, I'm trying to save the world and steer it towards a better ending…But I'm the final boss.
