Multiple female protagonist group chat system with few main storylines

Bai Feng arrived in the Honkai world and obtained a socialist blade. He arrived before the second Honkai, and everyone around him seemed to know him.

Otto: Long time no see, old friend.

Xilin: Brother~ I miss you.

Kiana: You stinky white wind! What are you doing now!

Good news, he's transmigrated to the world of anime! Bad news, no cheat codes! Su Mu transmigrates to a crossover anime world filled with slice-of-life stories, but all he gets is a broken Sword Saint System. The system can provide him with sword techniques from various worlds, but it can't teach him them immediately; he has to learn them through his own efforts. Su Mu practices diligently and eventually becomes a sword master, but the comfortable life of modern society troubles him. No one can challenge him, and he finds amusement in beating up thugs at Soubu High School. Until one day, he obtains an Infinite Flow System, allowing him to transmigrate to different worlds and challenge powerful figures from those worlds. Su Mu has completely opened the door to a new world! *The Failed Knight*, *Black Bullet*, *The Burial of Freeland*, *Ascendance of the Fearless*, *High School DxD*, *DanMachi*, *Type-Moon*, *Honkai Impact 3rd*... From then on, Su Mu's fame spreads throughout various worlds. (Main world mixed with Aoyama Gyoukai, randomly transmigrating to Infinite Flow worlds)

By chance, Li Bufan transmigrated to the mortal world, becoming a disciple of Qingyi Jushi on Hainan Crane Island in the Chaotic Star Sea, and simultaneously awakening a daily sign-in system. Watch as Li Bufan begins his journey from the Chaotic Star Sea to dominate the cultivation world!

Zhu Canglin was reborn as the eldest grandson of a non-existent emperor in the Ming Dynasty. He initially thought this was the historical Ming Dynasty, but it turned out to be a world of martial arts, or perhaps even a world of immortal martial arts. The Hongwu Emperor, Zhu Yuanzhang, possessed unparalleled martial prowess, and his crown prince, Zhu Biao, was skilled in both literature and martial arts, commanding the respect of all in the Ming court. The four great clans of the Sui Dynasty, the two demonic sects, and the six paths of the underworld! The Beggars' Sect, Shaolin Temple, the Power Sect, the World Society, and the Golden Wind and Fine Rain Pavilion of the Song Dynasty. In the north, there were Lei Family Fortress, Wangcheng Mountain, Tianwaitian, and Wushuang City! In the south, there were Longhu Mountain, Wudi City, Liangchan Temple, and Rotten Camel Mountain… The martial world, the imperial court, national destiny, fortune, and the Way of Heaven! In this era of great strife among the nations, who will rise and fall? Zhu Canglin awakens a cheat code: a sign-in system. He starts with the Innate Qiankun Skill and the Luo Wang assassin group, suppressing all dissent within and outside the court. Years later, after slaying immortals, treading the Heavenly Dao, and killing gods and demons…

Transmigrating to the Douluo Continent and becoming Huo Yuhao, he unexpectedly arrived in the Douluo Era 1 and even activated a diary system, earning rewards simply by writing in his diary each day. Originally, he planned to develop his strength discreetly, focusing solely on becoming stronger and building his career. However, as he wrote, Huo Yuhao noticed that all the female characters were acting strangely. Bibi Dong and Qian Renxue were openly and secretly vying for his attention. The Ice and Snow Emperors had transformed into human form, and the dormant Gu Yuena had prematurely awakened, bringing her auspicious beast to his door. Even the three beauties of Shrek Academy had abandoned Shrek Academy, revolving solely around him. Was it them who were acting strangely, or was it him? Xiao Wu: "Yuhao, I'm really not your mother-in-law, please don't call me that anymore!" Qian

Having traversed various anime worlds for over twenty years, Bai Ze suddenly became bound to a system that allows diaries to come true.

"Wait, are you going to publish my old cringey diary entries?!"

No!

The diary was published, and the whole world burst out laughing!

"Communicating with spirits and deducing fate? This kid isn't afraid of shortening his lifespan!"

"The author must have written it at night, because they're busy dreaming during the day, hahaha!"

"XX Hospital? There's a terminal case of chuunibyou here. Yes, hopeless!"

People just thought it was a child's delusional fantasy and ridiculed it.

When the relevant personnel verified everything, they were all shocked!

The Most Wicked Curse Master: "Holy crap! There really is a thousand-year-old brain?! Thank you so much, I'll follow you from now on!"

Vongola Special Forces: "Useless Tsuna is the disciple of the Great God? No wonder that bastard boss couldn't become the Tenth Boss!"

The Walking Grim Reaper: "What? I have the blessing of the Grim Reaper, which is why I die wherever I go?!"

The winery's model worker said, "No wonder Vermouth looked down on me. I admit defeat to him!"

Dragon Maid: "I want to be with you forever!"

As a transmigrator, Shirakawa Haruma naturally obtained a cheat system—a system formed from a wisp of divine power from an unknown deity. Just as he was preparing to drop out of school and embark on an extraordinary journey, he unexpectedly discovered that this was a crossover anime world!

Currently, the tentatively confirmed female leads are Kaguya-sama: Love Is War and Kasumigaoka.

In the new era, the city I live in is known as the safest place in the world... because I, who had become a demon, was caught.

Many young girls have heard an urban legend:

Legend has it that at a certain crossroads, there exists a pawn shop called No. 0, whose owner is a demon.

The devil will favor beautiful girls, granting their desires and tempting them to fall.

...

"Mr. Su Yun, what do you think of the comments above?" asked Eriri, the "loser," holding the microphone.

"Well..." Su Yun smiled slightly and put the clown mask on Eriri's face. "Is it possible that this isn't just a rumor?"

A cultivator accidentally enters a crossover anime world and embarks on a journey into the God's Space (not the original). (Multiple female leads, including Yukinoshita, Ryo Yamada, Ryougi Shiki, and Ai Hayasaka)

Mission worlds (Fate, Akame ga Kill!, Naruto...)

(I didn't get the pacing right. There will be a lot of Yukino's scenes at the beginning, so I can only finish it with Akame ga Kill! I'll revise it later.)

(The score will increase later after the initial release)

Minecraft, anime/manga crossover, multiple modules, equivalent exchange, electricity generation. Invincible protagonist (but will evolve), chaotic neutrality, interdimensional trade, a fun character, no female lead but has maids. I've read almost all the Minecraft books on Tomato, so I'm writing this one for fun.
