I'm a time traveler and a complete 2D otaku. My lifelong wish is to spend the rest of my life with a paper-faced wife, while also saying "no" to 3D women. Well, it seems half of my wish has come true. One day, I was pulled into a mysterious chat group. Glancing at the member list, I fell silent. [American Scythe]: Just blew up a building. If any jerk dares to say anything again, I'll be the next one to go. [Devil Kinniku Rin]: Damn it! I've spent all my gems this month! Anyone got a way to get some money? Urgent, waiting online! [Herrscher of the Rice]: Tonight's dinner is tempura, Kiana... Oh, sorry, I sent this to the wrong person. [Marin]: Ahhhh! Anyone got any new slimy girls? Such love! ...Looking at this group of friends, all with different styles, but all my wives from my past life, I fell into deep thought again. Wait, isn't this a "2D Beautiful Girls Chat Group"? Why was I, a man, dragged into this?

When a modern soul named Lin Mo awakens in despair, he discovers he has been transformed into Rengoku Hishin, the young adopted son of the Rengoku family, and finds himself in the world of Demon Slayer, where man-eating demons run rampant. Fate has bestowed upon him cruel trials, but also a unique gift: deep within his soul is the unbroken legacy of the legendary swordsman Kenshin Himura's "Hiten Miken-ryu" (Hiten Miken-ryu), along with a profound memory of the tragedy of the original story.

Holding the legacy in hand, yet burdened with regret, Fei Xin vowed: Never let those warm lights go out again! He combined the essence of Hiten Miken-ryu's "super speed" with the breathing techniques of the Demon Slayer Corps, forging his own path on the brink of life and death—**Fri no Breathing**! The crimson blade blazed like a meteor, piercing the darkness, imbued with the swiftness of thunder and the scorching heat of fire, and bearing the conviction to protect and not kill.

Starting from the arduous training in Narrow Mist Mountain, Fei Xin used the red blade in his hand to slash towards his predetermined tragic fate.

Thousands of years have passed, and the Invisible Empire has returned. But before them stand three insurmountable mountains. ——The invincible numerical monster, the super hybrid, the "All-Killing" Captain of the Thirteenth Division, Ichigo Kurosaki. ——The Touching and Inspirational Emperor, the Lord of the Soul King Palace, the "Dream Collapse" God King Aizen Sosuke. ——The veteran time traveler, the System's favorite son, the "Fighting God" Second Generation Captain Shinomiya Takashi. ... "...I see, a nightmare? What a good omen." "Your Majesty, what are you talking about?"

Having transmigrated into the world of Detective Conan, I gained access to the Daily Intelligence System and, incidentally, adopted the "Death God Elementary School Student," Conan Edogawa. [Daily Intelligence: Black Organization members Gin and Vodka will be heading to Dorobiga Park for a transaction. They are carrying a Beretta M92F, Browning, and a box of APTX4869. The car door can be opened by bending a coat hanger, and the engine can be manually started... as shown in the picture!] [Daily Intelligence: Kudo Yukiko has returned to Beika Town from Los Angeles to meet her 'second husband,' Conan's adoptive father, whom she has never met.] [Daily Intelligence: Eri Kisaki, having learned that you are mentoring her good-for-nothing husband and taking care of her daughter, decides to pay you a visit.] [Daily Intelligence: Amuro Tooru finds your interactions with Conan unusual and decides to come and work for you.] [Daily Intelligence: Vermouth is very interested in you and is preparing...]

As a time traveler from the Harry Potter universe, Vilan Costa always considered himself lucky. This was because in the timeline he traveled to, the infamous Voldemort had just reached the pinnacle of his power when he was assassinated by an unknown powerful wizard. He and Harry enrolled at Hogwarts at the same time, studying together in Gryffindor House. Harry lacked the lightning-shaped scar and the reputation of a savior, but he had both parents and a happy family. Vilan spent his first three years at Hogwarts uneventfully, until the summer vacation of his third year, when everything changed. His right eye developed a problem. After several days of unsuccessful treatment, it gained a unique ability—in short, it could accurately detect tiny marks on objects...

[Apocalypse Summoning Style, mainly based on the second game (including Genshin Impact: Collapse of Iron and Desolate Zone Zero) and anime]

Xie Yuhan traveled through time and space and became a dying scavenger, and was about to be devoured by wandering souls from the very beginning!

Little did they know that this was just the most insignificant appetizer of the end of the world!

In the moment of despair, the [Spirit Summoning System of Heroes from All Worlds] is activated!

While others are still contracting imps, my novice gift pack can directly summon the Sword Flag Lord Heatherin from "Starry Sky Railway"!

However, this is just the beginning!

What? The genius of the Ghost Control Association is still gloating over contracting a hundred-year-old vengeful spirit?

Sorry, my "Genshin Impact" Keqing, with one move of Tianjie Patrol, flattened the haunted department store!

My Geo Lord Zhongli, with one Sky Star shot, directly wiped out the D-level restricted area!

Saber's sworn holy sword, Nero's devilish right arm, the hail of bullets from the female wanderer...

Above the demons and gods, shadows called "Apostles" and "Gods" descend...

I will lead the heroic spirits of all realms and cut open the end of the world with one sword!
