Chrome Shelled Regios - Volume 9, Chapter 3 — Wish

Zavier met Cosmic Consciousness after his death. He was satisfied with every system that Cosmic Consciousness exhibited, so he wanted all of them. Surprisingly, the Cosmic Consciousness obliged him.

Zavier was reborn in an isekai full of magic and alchemy. Now, he had many routes to upgrade. Interestingly, to coordinate these systems, Cosmic Consciousness gave him the gift of being able to duplicate himself. He could clone a finite number of himself to manipulate these systems.

By the way, it wouldn't appear NTR or some bullshit harem of courtships. MC of course will have harem but not for cliches.

“Marry me under the conditions that we will divorce in 5 years.”

A prominent tech mogul from another world, Ye Zhuo, was reborn as the fake daughter of a wealthy family. In the past, the fake dog in the manger was loathed by everyone in her social circle and was notorious for her foul reputation. She was not only an illiterate deadbeat but also an illegitimate daughter who was mocked. “She is not even worthy of being the real daughter’s little finger!” “Illegitimate daughter! Shameless!” In response to that, Ye Zhuo simply chuckled. ‘Heh-heh… fake daughter? Illegitimate child?’ Despite being dealt a bad hand of cards, she could still shake up the world and stir up a storm!

She went from being the fake daughter of a wealthy family to the CEO of a renowned tech company and went from being a deadbeat to a talented girl that everyone envied – from having nothing to being at the top of the world!

Let’s feast our eyes upon how she put on the act of a lifetime!

The most famous deed of this princess was her words to her younger brother Liu Ziye.

When he became emperor, she told him, “Although your highness and I are of different sexes, we are the children of the same father. Why can you sleep with so many different women, while I must be only with my husband? This is so unfair!”

And after the Emperor Liu Ziye heard his elder sister’s words, he ridiculously thought it made sense. So he immediately corrected his “wrong ways” and painstakingly selected thirty handsome youths for her to enjoy.

Chu Yu awoke in the princess’s body and realized that she had obtained a male harem of three thousand; should she take just one to drink, or keep all of them?
