Ji Ran traveled to the Collapse World. In this world, which was extremely hostile to men... well, humans, Ji Ran felt a little panicked. However, after obtaining the [Dungeon System], he felt that his survival might be somewhat guaranteed. However, there were two options for the dungeon. The first was to clear the dungeon alone. This was too difficult, so he skipped it. Even if one person buffed the player, he still had to skip it! The second option, while the system's buffs would be weakened, would randomly match players with other players. So... Kiana: [Huh? This world actually has so many fun things?] Alicia: [Hehehe, it seems I'm popular elsewhere, too?] Bronya: [Is this a new game? Okay, Bronya accepts the challenge! Watch Bronya clear it with one life!] Raiden Mei: [I'd like to ask, this dungeon allows me to become stronger and control the power of the Herrscher Core by increasing my natural strength, right?] Mei Raiden: [What the hell is this Shenzhou home cooking 300-style dish? (╯‵□′)╯︵┻━┻]

After traveling to the world of anime, Hikage Miyauchi obtained a magical diary. As long as he wrote in it every day, he would get rewards.

But he had read diary online before traveling, and he knew that what he wrote would most likely be seen by the heroines of this world.

As a salted fish with no ambition, Hikage Miyauchi immediately decided to be a pure fun person in this world.

"What era is it? Who still writes traditional diaries?"

"No one is really willing to write their true feelings in a diary and then be watched by countless heroines, right?"

"My mother told me that this world is very dangerous. Boys must protect their privacy when they go out, so don't think about coming to me. After all, I am a man you will never get."

As Hikage Miyauchi continued to write in his diary, an "Avengers Alliance" composed of heroines who could see Hikage Miyauchi's diary was quietly born.

They gathered together for only one purpose, that is, to find the owner of this diary and ravage him inhumanely!

Illya: I lived with Saki for ten years! We slept together! We bathed together! What about you? Miyu: You did that? I lived with Subaru too! In those difficult days, we relied on each other. And I'm Subaru's older sister! Illya: Waaaaah~ So what if I'm your older sister? An adopted sister can get married! Can you do that? Miyu: We're not related by blood anymore, why can't we?! Chloe: Stop arguing! My first kiss wasn't with you, Illya, or you, Miyu, but with me, Chloe! Illya, Miyu: You're the enemy! All the girls: Wait! We haven't even said anything yet! Saki: This...this is scary. (Hides head and crouches down, trembling)

[Pokémon Eevee][Harem][Invincible][Decisive Killing][Fast-paced]

This book is also known as: "They all want to see my Eevee do a backflip"

Qin Feng traveled to the world of Versatile Mage.

After receiving an Eevee during a dimensional summon, Qin Feng was forced to become a glorious Eevee poop scooper.

At the same time, because of Ibrahimovic, he reached the peak of his life and married beautiful and wealthy women.

Mu Ningxue: "I heard your Eevee can do backflips. I'd like to visit your house tonight. Is that okay?"

Mu Nujiao: "I heard that your Eevee can dance. I want to go to your house tonight to see it. Is that okay?"

Mochizuki Chisaki: "I heard that your Eevee can walk on a tightrope. I want to go to your house tonight to see it. Is that okay?"

Irene: “…”

…

Ibrahimovic: "Ibrahimovic! Ibrahimovic! (I don't know any of these, don't come over here!!!)"

Qin Xiaonan accidentally traveled to the world of Versatile Mage and gained a powerful clone, the Desert Emperor in the League of Legends.

Then, in the Demon Empire of the Sahara Desert, the sun disc descended and thousands of powerful desert soldiers appeared, helping the Tsar to defeat the original Lord of the Sahara and become the new King of the Roof of the World.

However, who would have thought that one of the most powerful emperors in the world would be the incarnation of a magic apprentice who had just awakened his magic?

A child of an aristocratic family, backed by a powerful clan.

Qin Xiaonan has a clone, the Queen of the Sands, who gives him the support of a powerful demon empire and an inexhaustible supply of essence, making him the most heroic wizard.

At the same time, his main body breaks through, and he will gain another clone every time he adds a new system.

Break through the intermediate level, awaken healing magic, obtain the clone Soraka, the Son of the Stars, walk the world and heal all living beings.

Breaking through the high level, awakening the space magic, obtaining the clone of the Void Queen Belvis, appearing in the Alps, the "backbone of Europe", and creating a new demon empire.

Breaking through the super level,...

“I suddenly discovered that this world is dangerous today.” Bai Zhi looked grave as he typed out a line of text on his computer.

“When I went out today, I came across some poor guy getting bitten by another person. Luckily, a few brave guys rushed out to bring the criminal to justice, but when the person who was bitten struggled to stand up, he was immediately beaten to the ground by one of those who had supposedly saved him—and then, they called the police! I’ve watched more than enough modern movies to know what happened. The zombie was taken out before the virus could spread.”

“Last time, you told us about a few guys saving humanity from an alien invasion… This time, it’s a zombie outbreak?”

There was an exasperated response from the chat box.

“So how was that dangerous?”

“There are also several girls who are fighting tooth and nail for a piece of me! It’s totally Hell in here, don’t you think it’s dangerous!?”

“???”

Li Lin: I was dragged to the Fourth Holy Grail War, but I'm not a Master, and I'm not a cheater. How can I win? I'm waiting online, it's urgent. Aige: The Holy Grail War is so simple, but if it ends too quickly, the honeymoon will be ruined. How can I make them stronger? I'm waiting online, it's urgent. "The bread here is so cheap. Is there a discount because I'm the 100th customer?" "No, that's not the case." "Why?" "Because my name is Sajo Aige, and I—love you."

The fake Holy Grail War in Xueyuan City is about to begin.

Moran, who traveled to Type-Moon, is thinking about how to pass the level with one life!

Waiting online, urgent!

Ding! Successfully activated the life simulator!

[You expelled the foreign Olympus Twelve Mecha Gods, took the hand of the Earth Mother, and re-opened the country and mythology]

[You are the lord of the Millennium City named Brunstad, and the king of the earth that Zhu Yue loves]

[You are the last king of the end of the Age of Gods, who single-handedly prevented the Age of Gods from fading, and made the Age of Gods Britain continue to this day]

Behind the brilliant and dazzling life simulator.

Moran is facing -

Elquet: "Didn't you say that the Millennium City would pick me up? Why did you come to participate in the Holy Grail War!" Altria

: "Elbow! Come back to Britain with me!"

Elly: "Moran! What's wrong with these women!?"

Looking at the group of confidantes who are constantly approaching.

Moran feels that this will be the most difficult Kidney Cup War in the world.

After waking up, Lin Jiuan found himself traveling through time and space and became the sixth beast of Type-Moon.

In order to avoid the outcome of carelessly eating his own mother, Lin Jiuan cut off his connection with the underground Holy Grail and fled to Fuyuki overnight.

Although there was no mana supply, it didn't matter. As the sixth beast, Lin Jiuan converted his power into the system. As long as he could make those heroic spirits fall, he could get system rewards. From the time he was adopted by the Tosaka family, it was his turn to show his skills...

Rin? Sakura? Why are you two little brats looking at me in a weird way?

Orange, Altria, how come you guys with thick eyebrows and big eyes are so perverted?

No, Irisviel, Brunhilde, be reserved, you have families, right? !

What the hell is it about snatching my custody?

Meili: "Hehe, little guy, you don't want Ai Ge to know that you are surrounded by women here, right?"

Lin Jiuan: "???"

"You bad women stay away from me!!!"
