(Urban daily life + apocalyptic system + superpowers + no female lead + brains online + I'm only eight years old + martial arts + apocalyptic survival mission + space + pets)

Life is like a multiple-choice question; every choice you make determines your future.

Xiao Chen transmigrated from Earth to Blue Star eight years ago and finally awakened the system, only to discover that the Doomsday Selection System was fifty years ahead of schedule, and the spiritual energy revival and doomsday would not arrive until fifty years later.

An eight-year-old child, equipped with a system that arrives fifty years in advance, can level up by swatting a fly and save his system friend from fifty years in the future by burying something, becoming the man no one has ever seen in the apocalypse.

As his strength grew, Xiao Chen discovered that the apocalypse fifty years later was actually caused by human intervention. In this time and space, there were also ghosts, blood corpses, and monsters.

I traveled through time and space and became a young master and got a supporting role system. Forget it, it's just a supporting role. I eat and drink as I should, and occasionally I can help the protagonist and get some benefits. But what's the situation now? I say, protagonists, why are you all fighting for me? Hey, hey, wife, they don't mean to rob me, don't just come at me with a knife!

Mo Chen traveled to the interstellar era thousands of years later, and thought he would live a dull life. But when the system he carried with him woke up, he found that everything had changed! System, you let me use the game plug-in to travel through the heavens and myriad worlds, and it would be fine if I was invincible from the beginning! But, what the hell is this festival activity of yours? Qingming Festival, a hundred ghosts parade at night! Nie Xiaoqian, Sadako, and all kinds of ghosts from the heavens and myriad worlds appeared in the magic city of the interstellar era! Dragon Boat Festival, the Dragon Emperor appeared! The legendary Qin Shihuang resurrected and returned, and the immortal terracotta army reappeared on the earth! Double Ninth Festival, nine dragons pulled the coffin on the top of Mount Tai; on New Year's Eve, water monsters ravaged the Pacific Ocean. When the strong men of the heavens and myriad worlds...

PS: A relaxed, everyday life with a slow pace, no babysitting, and no need to chant spells to follow the plot—all wizards agree. However, Miss Loira Hamilton, a Veela half-blood from Durmstrang Academy, broke all that. At a young age, she was recognized as a member of the Wizengamot Wizarding Council, renowned as a master of magic circles, an expert in ancient runes, and known as the "Silent Witch" for her mastery of silent spells. "Ms. Hamilton is the finest professor at Hogwarts." — Hermione Granger's memoirs. "Miss Hamilton could very well become the next Chief Witch of the Wizengamot." — Dumbledore in The Prophet. But few know that Miss Loira Hamilton is actually a socially anxious person, so timid she can't even interact with others. Only the few of us, her close friends, know all this...

Lan Feng was summoned to a strange world by a terminally ill little girl's wish. Forced to accept a bargain, he must live on in her place.

She was reborn, but the price was to fulfill the girl's last wish. She experienced new things the girl hadn't experienced before, like making friends.

But she was first approached by a pink-haired, yandere little girl.

"Lan Feng, be my only one, okay?"

She then made many friends, but they didn't seem human.

Loli Mom: Mom doesn't approve. Want a hug?

Dark Loli: Lan Feng, fight me for five hundred rounds!

Being treated as a flower thief at the beginning, the golden-eyed fairy picked up the sword and chopped him? Xu Pingqiu said he was not panicking, and showed his extraordinary talent. He entered the top holy land Tianxu, thinking that the immortal path was open and magnanimous, but who would have thought that the style here was strange! The righteous way was full of life, and the devil's way was abstract. It turned out that the purpose of cultivating immortals was to make trouble? ! What's more terrible is that the master and the sisters are too tempting! The cold Taoist master not only has white silk, but also indulges me; the cute sister is always close to me and asks for hugs; the arrogant sister is even more happy to tease me... Xu Pingqiu covered his heart of Taoism that was about to break: Master and sister, please let me go, this pure yang body can't stand it! In this world of cultivating immortals where there are constant activities, Xu Pingqiu decided to whip the world in his own way! Welcome to watch the large-scale documentary "The Things I Did When I Defrauded My Master and Destroyed My Ancestors in Tianxu"!

Chu Feng transmigrated to the world of cultivation and became a menial servant in the Xuanjian Sect.

They happened to be caught in the great war between good and evil, with countless righteous sects besieging the evil path.

When gods fight, mortals suffer. In order to replenish their forces, the sect also issued a mount to each of its servants.

Chu Feng's acquisition of the lowest-level demonic beast made him the laughingstock of the entire sect.

Unexpectedly, that monstrous beast was actually the transformed form of the defeated demon empress...

He looked at his fellow Daoists who were riding their respective mounts to the battlefield.

Chu Feng rode the demon empress onto the battlefield of the war between good and evil.

When the demon empress came to her senses, she turned around and was about to take his life!

"How dare you humiliate me—you shall die!!!"

Unfortunately, the two had long been cursed by the sect with a life-locking curse; if one of them died, the other two would also die.

Chu Feng immediately hardened his stance: "I'll give you two choices! Become my mount or..."

Finding Kiana and Bronya during my travels should have been a happy thing, but, Your Excellency, what's wrong with you?

The captain was dumbfounded when he saw the blonde girl in front of him.

Kiana and Bronya also seem off.

One day, the captain in the basement regretted his actions, saying, "I was so stupid. What kind of girl is so overly familiar, and only with you? Besides, Kiana even has a love interest in the story."
