After traveling through the world of Demon High School and wandering around in it for a thousand years, when Chen Eliog became the fifth demon king of the underworld, he received an invitation from a dimensional chat girl.

Out of boredom, Chen Eliog chose [Accept].

Cang Yue: Welcome newcomer! I am the strongest fighter among all the girls, let me know!

Esdeath: The person above is talking nonsense! I am the strongest fighter among all the girls, let me know!

Yukinoshita Yukino: Hello newcomer! As an ordinary person, I am trembling between two big guys!

Shinomiya Kaguya: +1!

"…………"

Chen Eliog: "Thank you for the invitation! I am in hell and have just become a demon king: I have official business to attend to, so I will hide for the time being."

Having transmigrated into various anime worlds, Yu Sheng Qiuzhe obtains a god-level choice system. While walking the streets at night, he encounters a unconscious Rem, who is leaning against a corner. Out of a helpful spirit, he picks her up. Just then, a fierce shout comes from behind: "Let go of that girl!" "Ding! Master is about to face Tatsumaki's pursuit. Please choose!" "Option 1: Throw Rem at me! Decisively throw Rem at Tatsumaki while shouting 'Throw Rem at me!' Reward: 'Mystic Eyes of Death Perception!'" "Option 2: Kneel and beg for mercy! A true man can bend and stretch, knows when to advance and retreat! Reward: One bottle of Body Extension Potion (one-hour effect)!" "Option 3: Fight to the death! Never compromise or admit defeat until the very last moment! Reward: ..."

Transmigrating into the world of the "Hakoniwa" (Little Garden) in the world of crossover anime, Izayoi Sakamaki, while waiting for her invitation to the Little Garden, was invited to the Multiverse Chat Group and became its strongest member. Esdeath: "Izayoi, I will definitely not let you leave me too far behind!" Rikka Takanashi: "My contractor, following the ancient oath..." Nagatsuki: "You are hundreds of times stronger than the True Ancestor!!!" Touhou Project: "Um... Boss, do you have any extra Third Star Particles? Can I borrow some?" Gilgamesh: "I, the King, declare you the strongest!" Brunhilde: "Lord Izayoi, please save humanity!" Izayoi Sakamaki: "Thanks for the invitation, just arrived in the Little Garden, challenging the Celestial Theory." With her absolute power, Izayoi Sakamaki also became the chat group's sole administrator...

Li Ke, a high school student who just finished the college entrance examination, accidentally obtained the Wanjie Anime Tracking System.

But when he was having a nightmare, he turned off the system sound, so Li Ke, who started to follow the anime, unknowingly pulled Wanjie to follow him.

As a result, different worlds have undergone different changes...

After traveling to the continent of Teyvat, I unexpectedly met General Thunder as soon as I arrived. But it doesn’t matter, she has the power of the God of Thunder, and I have the power of the Herrscher of Thunder!

General Thunder: "What kind of power is this? Why can you control the power of thunder that is more powerful than mine?"

Facing the incredulous look in General Lei Dian's eyes, Chen Ran smiled crookedly: "Can you be called the God of Thunder?"...

Kiana: "Yun Ling, this time... I won't be deceived by you again!" Mei: "Dear Mr. Yun Ling, have you forgotten that we're engaged?" Bronya: "Yun Ling... you must love yourself!" Yun Ling looked at the familiar yet unfamiliar Big Three and wiped the sweat from his forehead. A mad suffocation was spreading, but then he turned around... Alicia: "Ling, you've been naughty~, well, but for the sake of so many beautiful girls, I forgive you~♪, hehe..." Eden: "Little Ling, come into your arms. I'll sing you to sleep." Weiwei: "I finally found you, Ling. This time, don't even think about abandoning us..." Surrounded from both sides, Yun Ling panicked and tried to flee on his sword. Fu Hua: "Where are you going?" Li Sushang: "You can't escape this time." At that moment, a shadow appeared at his feet, completely engulfed by the suffocating feeling of a python's coils (Shi). (The main storyline is sweet and warm, but the simulator is annoying)

Kiana: "Yun Ling, this time... I will never be deceived by you again!"

Mei: "Dear Mr. Yun Ling, have you forgotten that we are engaged?"

Bronya: "Yun Ling... You must love yourself well!"

Yun Ling looked at the familiar yet unfamiliar three families, wiped the cold sweat from his head, and a Shura field was spreading madly, but when he turned his head...

Alicia: "Ling, you are not good~, well, but for the sake of so many beautiful girls, I forgive you~♪, hehe..."

Eden: "Little Ling, come to your sister's arms, and your sister will sing to you to sleep."

Wei Wei: "Finally found you, Ling, this time, don't think about leaving us again..."

Yun Ling, who was attacked from both sides, was a little panicked and was about to fly away on his sword.

Fu Hua: "Where do you want to go?"

Li Sushang: "You can't run away this time."

At this moment, a shadow appeared under his feet, and the suffocating feeling like a python wrapped around him completely swallowed him (history).

(The main storyline is warm and sweet, but the simulator is annoying)

Lin En traveled through the world of Soman and was reincarnated as a half-blood demon.

Fortunately, the awakening system allows him to recruit his own demon family.

Not only can he reincarnate his family into special demons, but he can also give them an upgrade system similar to the grace of Jicuo.

So...

'Secretary Demon' Kasumigaoka Utaha: I understand everything!

'Psychic Demon' Yotsuya Miko: Evil spirits, retreat!

'Sword Demon' Busujima Saeko: Only killing is the most enjoyable!

'Food Demon' Nakiri Erina: God's Tongue, let me see your limit!

In addition, Lin En also has the 'Devil's Contract' that can cross the world.

Good news: I became Enkidu. Bad news: I transmigrated to the world of Honkai Impact 3, and their eyes are all weird! In simulation: [Blocked a hit from the Herrscher of Death for Kevin, gained Death Resistance A+] [Mébius gave up his ideals for you, gained a handsome young man A+] [Became the only light in Otto's heart, gained Spark Prism (Petrification) EX]..... Otto: "Enough, Kallen! Get out of here with your pink donkey! Enkidu is mine!" Raiden Mei: "Enough! We are good sisters, that's true, but I am Enkidu's first girlfriend!" Bronya: "Hey~ Father, didn't you and Mother agree to go to the amusement park with Bronya and Seele today?" Alicia: "Sorry, Mei~ The battle for the main wife is always like this????~" Enkidu: "I am the zeroth seat of the Fire Chaser [Heavenly Lock], I came in response to your cry for help, that's right, I am your mast.

Himeko Murata has a recent problem. She thought waking up to find her entire class transformed into Herrschers was absurd enough, but... why did she wake up to find her entire class of aliens, with not a single native Earth life form in sight?! The whole class has become aliens! Kiana from Nebula M78, Bronya from Krypton, and Raiden Mei from Galife. Faced with the students' new ancestral origins, St. Freya, the Far Eastern Demon Cave, has earned a new title: the Cosmic Demon Cave. Rumor has it that even Headmistress Theresa is ecstatic.
