[System + Reasoning to Solve Cases + Single Female Lead]

Deliveryman Su He accidentally got involved in a mu*der case, and at the same time bound a top-tier selection system! As long as he makes a choice, he will get a reward! With the help of the system, his life trajectory gradually deviates: Hey, I want to call the police, Mingjia Community, Building 2, Unit 603, someone committed mu*der… Yes, I’m safe now… Two people died… The mu*derer? Well, I locked him outside the door… I have no relationship with the deceased, I’m a deliveryman…

Officer Wen: Why do you, a deliveryman, always appear at the crime scene?…

Su He smiled and said, “If I say this is a coincidence, do you believe it?”

Lin You traveled to the Peerless Tang Sect period. Not only did he only have half-level soul power, but his martial soul was so tiny that it could not be distinguished by the naked eye. He was jokingly called an awakened air.

Air martial soul?

Wrong, it is the hydrogen element in the periodic table with an atomic number of one and a mass of approximately 1.660539040×10^-27 kilograms!

From simple human refining to complex planet reconstruction, the power of elements is endless, even the sun is in the bag!

As a parasite who wants to find a place to live and wait for death, and do scientific research at ease, Lin You doesn't want to provoke anyone.

But the God King doesn't agree. He wants to eliminate unstable factors for his ten thousand year plan.

Lin You: "Do you know how black holes are formed? Now, this star in my hand, which is formed by hydrogen, converts hydrogen into helium through nuclear fusion reaction. When the hydrogen fuel of the star is exhausted, the core of the star begins to shrink, and the outer layer expands, turning into a red giant."

"You don't understand because you haven't read books, right? After the red giant stage, the core will continue to shrink, reaching extreme temperature and pressure to form iron. When the fusion of iron no longer releases energy, the core will collapse, and the outer layer of matter will erupt in the form of a supernova. It's really good. You can hold on until now and face the supernova explosion. You are also very stubborn."

"But if it goes a step further and the mass exceeds the critical value, it will collapse in the core and form a black hole. Look, beautiful, isn't it?"

"Now, I'll give you this big treasure."

The God King is dead!

After traveling to the world of Star Dome Railway, the unique waste system of Cat Guest is unlocked. The more good deeds you do, the corresponding moral points you can get, and different abilities and skills can be extracted.

Bai Jun, who died suddenly at work in his previous life, thought he could live a peaceful life as he wished, but found that this system was not as simple as he imagined.

"Beautiful boy, Holy Judge of Heavenly Fire, Grace of the Sun, Reversal of the Art "He", Lightning of Platon Sanx..."

Oh, what did I do, is this still the system of Cat Guest?

Looking at the hidden Lu system of top students in front of him, Bai Jun felt that the ideal peaceful and beautiful life was gradually drifting away from him.

No, as a qualified social animal, as long as you learn to actively avoid all kinds of troubles and don't attack cute girls, maybe you can still keep a peaceful life.

However, as time went on, he suddenly found that there seemed to be a little more girls who took the initiative to approach him?

"No, why am I the one being attacked?"

In the book that travels through the catastrophe of all races, although the situation of the human race is in mourning, Chen Feng believes that with the protagonist, everything can be solved.

What's more, if you activate the eugenics and eugenics system by yourself, you still have to go home and give birth to a child.

In order to avoid competing with the male protagonist for a woman, she had to find her cousin first.

【Ding! You have successfully continued your bloodline, with 100 million bottles of top-grade essence-building liquid and one billion pieces of top-grade spiritual crystals. 】

【Ding! You successfully give birth to a son, and you will be rewarded with the secret magic Yuanling Holy Art, SSS power activation card, and the Law of Thunder...】

【Ding! You successfully gave birth to your second son...]

While the protagonist group went to the battlefield to kill the enemy bravely, Chen Feng was behind with his wife and children on the hot bed. Occasionally he would enter the battlefield of thousands of races and capture several saints from other races.

And the fate of the human race also ushered in a change on this day.

Chen Feng's children are all outstanding people.

The eighteen-year-old eldest son, on the day he entered the battlefield, he slaughtered the top ten demon generals with unparalleled blood!

The second son is in charge of thunder, and his powerful thunder shatters all enemies' illusions.

The third daughter mastered the power of light and melted countless alien nests.

Fourth son...

In another twenty years, the ten great emperors who will be the pillars of the human race on the battlefield will all be descendants of Chen Feng!

Half of the top one hundred geniuses in the human race are his descendants.

And Chen Feng is known as the light of the human race, the father of the great emperor, and the nightmare of all races!

At this time, Chen Feng discovered, why did the protagonist collapse?

I can't sign, I really can't sign!"

In the corner, Yin Lan was holding a roll of marriage registration forms from all over the world, squatting with her knees hugged and trembling.

"I once had a life that exuded the fragrance of being single, but I didn't cherish it. It's not until now that I'm entangled in love that I regret it."

"Signing one will mean a world war, not signing is a scumbag, signing both is a dead scumbag, if you delay for too long, you might even be divided into five equal parts by them."

He raised his eyes to look at the golden king in front of him, and under the urging of the desire to survive, the flame of gay love gradually ignited in his lifeless eyes.

"Ji, Jill, how about the two of us..."

"Get out!"

Where there is food, there is life.

Where there are music, chess, calligraphy, and painting—poetry and song—there is joy.

With a bit of wealth and fame, there is grandeur and ambition.

Gu Zhengyan transmigrated into an ancient world and, by a stroke of luck, won first place in a poetry competition and ended up marrying the proud and talented daughter of a marquis.

But their marriage enraged the Marquis so much that he kicked them both out.

Now back in his impoverished hometown with his new wife, Gu Zhengyan was feeling utterly defeated—until he realized his wife wasn’t like any ancient woman he’d imagined. She was incredibly talented... and incredibly proud.

Luo Shuyao:

“Gu Zhengyan! Don’t interrupt me while I’m talking! You must answer my question—no brushing it off, no pretending, no impatience...!”

Gu Zhengyan:

“…What do I do? I’m the one who transmigrated, and even I can barely keep it together…”

Note: The story begins with slice-of-life romance and gradually develops into action and intrigue.

Su Yian accidentally traveled to the world of immortal cultivation and became a professional stand-in

In a mission, Su Yian becomes the substitute of Chu Qingxian, the princess of the Xian Dynasty.

The attentive care and tenderness in every detail made Chu Qingxian the envy of all the female cultivators.

But Bai Yueguang always existed in the princess' heart until he came back one day...

Everyone thought that Su Yian, who was used as a substitute, would collapse, be angry, and be sad beyond control.

But he was unusually calm, like a different person

Until I saw the letter written by Su Yian and the sketch that was 80% similar to my own.

Chu Qingxian realized later that she had been used as a substitute for the past two years...

Later, Su Yian’s former “clients” all regretted it!

They all followed the traces and came here, even Su Yian and the others' white moonlight!

Princesses from other immortal dynasties are poaching his talents right in front of him!

The cold and aloof Fairy Qin turned into a yandere because of him!

The goddess of the immortal gate will not marry anyone else but him!

The Demon Sect Saint is madly in love and completely crazy about killing!

When peerless fairies appear one after another...

Chu Qingxian, who was used as a substitute, finally turned evil and mad, and suddenly woke up!

It turns out that Su Yian is her white moonlight treasure!

"He is my unique substitute, no one of you can take him away!"

Everyone is very curious, why are so many fairies crazy about Su Yian?

In response, Su Yian just smiled and said, "Because I am a professional as a stand-in, my record is verifiable."

Other 'male protagonists' appear and force him to leave?

Su Yian: "Cut off my source of income? I might as well become a professional villain."

After two and a half years of no contact, Yang Shu’s childhood friend suddenly returned, promising marriage the moment he paid the bride price.

He thought she had a change of heart—

But it turns out she was just looking for a gullible "nice guy."

Yang Shu cut his losses without hesitation:

Tired of this. Time to reset and start over.

And thus, the second playthrough begins—

Childhood Friend: "What kind of suitor acts like this? Where’s your attitude?"

Yang Shu: "Abnormal."

Childhood Friend: "You used to be so nice to me. Can’t we go back to how things were?"

Yang Shu: "Enlightenment."

Childhood Friend: "I already apologized. What more do you want?"

Yang Shu: "nice try."

Childhood Friend: "Last question—do you love me or not?"

Yang Shu: "I don’t’"

And so, she began to spiral into darkness…

Meanwhile, enter the socially anxious little rich girl:

Rich Girl: “Yang Shu, here’s 1 million for the summer. Friend subscription, one month.”

Yang Shu: “I’ll consider it a loan.”

Rich Girl: “Then I want interest. Hold my hand and walk me around.”

Yang Shu: “Deal.”

Rich Girl: “Yang Shu, in the animal world, friends can crawl into each other’s pouches.”

Yang Shu: “That’s a kangaroo.”

Rich Girl: “Yang Shu, the next payment for the friend subscription… might be late…”

Yang Shu: “??”
