I oversee the harmony among the heroines?

*Sigh* Lei Kongming sighed in frustration.
He was not a native of this world but a traveller from Earth. When he first arrived here, he thought he would become the brightest star of his generation.
And in a way, he did become the brightest star of his generation, but this world also made him feel powerless.
One of his earliest companions was his cousin, Lei Longwei, who stood with him throughout the journey—blocking enemies, gathering intel, and sometimes even blocking the shura field of his wives.
However, Lei Longwei always lived in fear. The reason was his sister-in-law, who is Lei Longwei's wife.
She is notorious for her violent personality, and her infamous golden scissors could make men cry out in terror. Those scissors were specially designed to turn men into eunuchs, and what made them even more terrifying was that they ensured that these eunuchs could never regain their ‘weapons’.
Naturally, his cousin's situation wasn't the only reason which made him feel powerless.
His own wife, Su Zhiyuan, who was also the head of the harem, often leaves him frustrated. She had a special hobby of inventing new things, especially pills.
The last time, she invented a pill that was ‘supposed’ to eliminate the need for humans to breathe, but it turned out to be a complete failure.
It was fine until now but then she dumped those millions of pills in the ocean.
Well… he was still willing to pay the penalty for illegal dumping, but those stupid pills caused all the sea creatures to mutate.
Then a fish revolution began, as the fish could now survive on land without water.
After Knowing that his wife has caused such a big trouble, he rushed forward to calm the chaos, but then she created another pill, insisting that this was a solution.
While he wondered what kind of solution it could be, he received news that her new pills could make cultivators permanently grow gills on their necks.
When he asked her why she is causing another trouble, she responded, "What trouble? Now that humans have gills, they can easily live in the ocean. Everyone can migrate there, leaving the land for the fish."
