[Prime Minister Cao] + [No System] + [Not Brainless] + [Alternate Universe]

A top parenting expert travels through history to a dynasty where the mortality rate of royal heirs is extremely high.

With the world collapsing at the start, his first task was to help the imperial concubine with her milk!

The imperial harem had three thousand beauties, and none of them were easy to deal with.

Shen Yulou worked as a nanny during the day and a male postpartum caregiver at night. He originally thought that the palace would be easy to navigate, but he never expected that he could only survive in the cracks!

The Imperial Concubine needs to stimulate lactation, the Empress needs to prepare for pregnancy, and the Princess needs to learn a skill—Shen Yulou is finding it difficult to cope!

(Multiple women, multiple women, multiple women—I'll say it three times because it's important!) He traveled through Viserys and even gained Ghidorah's favor. Is this still Game of Thrones? No, I'm invincible, do as you please.

(Not a crossover anime/manga universe, but set in the Akatsuki/Akame ga Kill! universe) "Ichijo, I bestow upon you the Imperial Arm Murasame to commemorate your achievements." "No, too much killing intent, it will harm my health." "What about the Demon Possession?" "No, Lancer's luck is E, how many masters has this thing killed?" "Gaia Foundation?" "I don't want to be a cross-dresser!" "Then what do you want? Tell me, and I will grant it to you." "I want the Demon God Manifestation!" "But, this Imperial Arm is on Esdeath, if you want it, wouldn't you be taking Esdeath home with you?" "Your Majesty is wise, I thank Your Majesty for the marriage!"

I was thrown into countless hentai worlds, forced to walk the path of scum to survive. I seduced married women with the fragility of a young boy, coerced girls with my blond hair, or engaged in forbidden school romances as a teacher… Now I have a new identity: the evil spirit of Babel, the doctor of Rhodes Island… the harem king of Terra. I will use the abilities of the underworld to change this land filled with tragedy. I was once a quality inspector at Type-Moon Heavy Industries, and I conquered the world in the name of Lance; those powers came with me. “Believe me, my becoming a harem king is all the world’s fault!” “I will save this damned world! To undo those regrets!” “Come, witness me as a player, as the Fourth Calamity!” [Erotic and exciting, five chapters a day, quality guaranteed, plenty to satisfy]

(American police + daily life + gunfight + promotion + mature woman)

Arthur Morgan is reborn in Los Angeles and discovers he has a Red Dead Redemption system.

He was once the King of Fighters in the West, the King of Widows in the West, the King of Hunters in the West, the King of Hello in the West...

Now it possesses the Death Eye, Widow's Affinity, Tracking...

Having been given a second chance at life, I will not be a bandit but a policeman. My goal is redemption and to save as many widows as I can.

"Sister-in-law, the eldest brother is watching!"

"Treat him like he's dead!"

...

"Sister President, I'm not a driver."

"Now, he's my personal driver!"

...

At first, Ye Chen just wanted to work honestly as a waiter in a nightclub to earn money and pay off his debts. But the women in this world are too crazy, so he had no choice but to be even crazier.

Reborn into the Great Wu Dynasty, Li Changsheng becomes a (fake) eunuch in the imperial harem. He aspires to be like Lao Ai, but instead becomes the strongest eunuch on Earth.

In terms of political achievements, he established schools, implemented reforms, rectified official corruption, swept across the land, and brought peace to the world for generations to come!

He fought against powerful ministers, but in the end, he inexplicably became the most powerful minister and the most treacherous traitor!

When it comes to economic development, he transformed the once precarious Dawu into a prosperous and powerful nation, even surpassing Tao Zhugong!

In terms of talent, if all the talent in the world were equal to one bushel, he alone possessed twelve bushels, and the rest of the world would owe him two bushels!

A man of many talents, he wielded power over the world when awake, and rested his head on the lap of beauties when drunk. Princesses, imperial concubines, noble ladies, and chivalrous women all loved and admired him.

...

The stunningly beautiful empress later looked back and thought: "You dog of a man, I asked you to manage the harem, how could you have dug it all up?"

No system + Rebirth + Time travel from American TV series + The Big Bang Theory + Lighthearted and funny + Academic genius + Slice of life + Verbal banter

Chemistry PhD Dai Jun is unexpectedly reborn in 2007, becoming David Zhou, an Asian physicist in the American sitcom "The Big Bang Theory." Using his knowledge from both lives, he narrowly lands a job at Caltech, becoming a colleague and neighbor of Sheldon and Leonard.

As the plot unfolds, Leonard falls head over heels for his beautiful neighbor Penny, only to be humiliated by his ex-boyfriend with his pants pulled down. David, a reborn individual, has a brilliant but ultimately flawed idea: find out the model number, buy Penny a TV, and give it to her as a hero?

Sheldon: A logical dead end! Morally depraved!

Leonard: For love, this plan is perfect!

Thus, the Frankenstein's monsters embarked on a hilarious and absurd journey to "change the TV".

Lin Jin, who transmigrated into the world of Detective Conan, discovered something amiss with his dreams. In one dream, he unleashed a barrage of attacks on Ran, but the next day, she lost her match due to a muscle strain. He dreamt that Eri Kisaki was investigating a case of female assault, and he offered to help, cooperating in reenacting the case, which gave Eri a breakthrough the next day. He dreamt that he trained with Sun Wukong, and the next day he had eight-pack abs. "It's a pity dreams are random, otherwise…" Lin Jin felt quite regretful. If he could, this thing would be far more useful than time stop.

Chief of Special Agent No. 76: "I just made a plan a second ago, and you told me it would appear on the desk of the Military Intelligence Bureau chief in the blink of an eye?"

The head of the Special High Section said, "Yoshi, this plan is flawless! What? This flawless plan has been publicly announced in Shancheng?"

Military Police Captain: "The leak of the battle plans of the major war zones is the responsibility of Unit 76 and the Special High Police!"

Shancheng: "What, Xiaohu has been promoted to the director of special forces? Don't panic, we will double the amount the Japanese give you."

Red Party: "Super double!"
