On his way home, Robos was killed on the spot by a security door blown by a typhoon, and his brains splattered as he traveled through time. The good news is that the Robos who traveled through time was not a Muggle, but a natural mutant. He was able to summon the security door that crushed him to death. The bad news is that because he was a natural mutant, his soul was mutated, which made most of the cultivation techniques incompatible with his innate supernatural powers. The good news is that he successfully arrived at Biyou Village and successfully learned the Divine Machine Hundred Refinements, which allowed him to change his fate and began to practice with great concentration. The bad news is that after only one year of practice, the story of Luotian Dajiao is about to begin. The good news is that the security door can travel to another world. The bad news is that the door will not tell you where the other world is, so you can only go there yourself...

[Various Anime][Chat Group][Slice of Life][Tokisaki Kurumi][Gradual Transformation (Completely becomes a woman in Chapter 40!)][Single Female Lead]

Transmigrated to a crossover anime world.

Li Yuan actually gained Tokisaki Kurumi's abilities!

The Zafkiel is unleashed: the First Bullet accelerates time, the Fifth Bullet foretells the future, and the Eighth Bullet creates clones of the past!

In this world of ordinary people, Li Yuan, who possesses the abilities of Tokisaki Kurumi, is almost invincible!

What Li Yuan didn't expect was that after obtaining Tokisaki Kurumi's abilities, his body also became the same as Tokisaki Kurumi's, but he was still a man!

Perhaps because her physical transformation was not complete, Li Yuan was unable to use some of the Zafkiel abilities she possessed.

Just as Li Yuan was pondering how to solve the problem of her ability being unusable...

In high school, students learn swordsmanship and other combat techniques. Quantitative indicators of physical fitness are an important criterion for university admission. Combat ability is a key subject. These are clearly standard urban martial arts styles. But can anyone tell me what the heck is that giant roadside advertisement for a mixed-race potion? Is the swordsmanship teacher from the Demon Slayer world, or the Pirate World? A new, incredibly popular restaurant has opened next door, and rumor has it that the chef is one of the ten most talented graduates from Totsuki. I turned on the TV, and it was broadcasting news about a meeting between the mayor and the head of Konoha Village. Celebrating the tenth anniversary of diplomatic relations between our city and Konoha. Something's a bit off about the style of this martial arts world.

[Quick Transmigration * Obsessive Villain * Frail and Clinging Flower * Male Lead's Unwavering Destiny * Sweet and Pampered Happy Ending * Slightly Popular * Directly Switches to the Villain's Arms at the Start] Can love that changes its heart still be called love? In this small world, the cannon fodder female supporting characters who were once favored by the male lead not only never received any recognition but were also arbitrarily controlled by their fates, ultimately dying tragically. The clinging flower Yu Xi arrives, fulfilling their wishes. The male lead hands her over to someone else, believing she still loves him. Little does he know, the person he pushed her towards is the perfect host of the clinging flower, possessing the most ardent and devoted love. As time goes by, Yu Xi is pampered by the rumoredly cold and cruel villain. How can the male lead, who has lost everything, regret it? Regret is useless; the frail and clinging flower is destined to be locked with the obsessive villain! And the frail physical characteristics in each world—[blindness], [aphasia], [immobility], [excessive sleepiness], [mimosis], [intermittent amnesia]...—will all become her weapons, not flaws. * [Note: The female lead's flaws will be resolved; standard happy ending] Tentative worlds (order not fixed): [A blind parasitic flower sent to a business marriage by her childhood sweetheart who changed his mind] [A melancholic courtesan given to her brother by her beloved] [A skin-thirsty noblewoman bestowed upon a powerful minister by a heartless emperor] [A young lady with intermittent amnesia manipulated by a playboy to toy with impoverished students] ... and so on.

Jock traveled through time, but unfortunately, to the wrong place. After achieving the three major accomplishments of time traveler, homeless person, and high school student, he still had to constantly evade the nagging of the One Who Returns All Things to One. Along the way, he encountered a resurrected fox, a famous detective who vowed to put him in jail, and a variety of other people. Armed with an axe, a greatsword, and a smoldering shotgun, he took a determined step through the neon-lit streets of Tokyo. "You little bitches, don't even think about getting in my way! Kill me!"

The bad news is that Ximen Huan traveled through time, but the good news is that the Marvel world has cheats, and as long as you sacrifice enough life energy, you can gain the ability to refine everything in the universe.

As Ximen Daguanren became more and more powerful, all the superheroes and super criminals in the American comic world were wailing.

You are aloof, you are great, you sacrifice us as stepping stones, please go and stun other worlds!

Ximen Daguanren: "Then I will show some kindness?"

In the basement, Lin Qing'an, shackled and bound, was writing a confession. "I was wrong, I was really wrong." "I shouldn't have used hypnosis to do whatever I wanted to the lovely Yukinoshita and my dear classmates." "I shouldn't have used force to enslave the noble Shinomiya and Nakiri." "I shouldn't have lured Emilia to destroy the world." "I shouldn't have..." As he wrote, Lin Qing'an was overwhelmed with sorrow, unable to stop. He was a good man, and now he had fallen to this state, all because of that damn simulator. [Note: This simulator aims to showcase the infinite possibilities of the future and does not reflect reality. Please play with peace of mind.] "If it doesn't reflect reality, then it's just a game, right?" That's what he thought, and that's how he played. But who knew that the stupid simulator would actually drag him into the simulation too! "Click—" Just as I was pondering, the basement door opened...
