Buhou kids! I'm not human anymore!

Wait, what's with the evil spirits?!

"I originally thought I was just an ordinary person." "Suddenly one day, a beautiful woman stood behind me and asked me to pull out that damn sword." "At that moment, I suddenly realized something was wrong." "But this is no big deal. After reading Le Morte d'Arthur, I am invincible here. As long as I don't give birth to Mordred, don't marry Guinevere, and honestly be a king, there will be no problems." "But...?"

He is in Type- Moon , and his sister is Illya

When a boy who has traveled to countless places arrives in a world of trees and sea.

He chose to join in, to become a part of the story, to experience it, to experience this "healthy, sunny, and positive" story.

"I don't really like tragedies in my notebook."

"Even the worst author can't write a story using the tears of a beautiful girl."

"Since I'm not satisfied with your story, then I'll have to write it myself."

These are the words this young man spoke to a certain being.

As the story unfolds, only the boy himself knows whether it is the story itself or the characters within it that attract him.

If we were to rank the difficulty of a time travel, there's the Extremely Easy difficulty, where you're born a sage; the Easy difficulty, where you can become a second-generation immortal; the Medium difficulty, where you're mediocre, with cheats; and the Hard difficulty, where you start as an orphan and are deeply in debt. Misfortunes often come with blessings, and blessings often hide misfortunes. Luo Yu, who traveled to the Starry Sky Railway world, was unfortunate, as his starting difficulty was hellish—he was born in the women's restroom. But Luo Yu was also fortunate, as he immediately achieved the only achievement in the observed universe—being simultaneously observed by the three Star Gods. Star God of Joy! Star God of Wisdom! Star God of Memory! Please grant me strength! Climbing out of the women's restroom and regaining my life—this is just the beginning of Luo Yu's gaming universe. Watch how Luo Yu manipulates the world of Honkai Impact 3rd and turns the tide! The main world of Starry Sky Railway is interspersed with the sub-worlds of Genshin Impact and Honkai Impact 3rd.

Because of the gambling system, Sodium Chloride must play the villain in every world, drawing the hatred of the Children of Planes. He must also survive to earn points. The greater the hatred, the more points he earns. To achieve this, he must resort to any means necessary: ​​deception, ambush, and sneak attacks, fellow protagonists. Upon seeing Frost Star, wearing the protagonist symbol, he quickly stood up with a snap. He immediately exchanged for the strongest body, the Herrscher of the Void, and faced his new target with beeeeeeer. However, the protagonist symbol on the "protagonist" he encountered this time didn't light up... But that's okay. Who am I, Sodium Chloride? Many people may not understand what it means to win 8.78 million points by using a blank character with 200,000 points to become an Apostle of God. We generally describe this as artificial. Gambler, "One Ku, Frost Star! Ma You Lai, Yabule Road!!" [Shocked] As your sister, Frost Star, please don't blame me for being mean. P.S.: If you want to raise a loli Yelena, I've already put it in the book~ [Laughs]

Alicia: "Oh, Xiaochen, you are so cute. This pink skirt must suit you very well! Oh, don't run~"

Mei Lei: "Su Chen, I am willing to fall into darkness in exchange for you returning to the light, just like you once saved me."

Xilin: "Brother, you said you would stay with me forever. This time I won't let you leave my side again."

Lin Zhaoyu: "Big Brother, do you remember that you still owe me a promise? I am willing to spend my life with you."

The Herrster of Knowledge: "Traitor, come and take my sword!"

Kal'tsit: "Traveler, what brings you to this land this time?"

"As you can see, I have come to break that destiny."

I am no longer being driven forward.

I have found my love.

I have been reborn.

[It's a bit watery in the early stages, but better in the later stages. The tempo is a bit slow.]

I almost got taken away by a truck when I went out! ?

Fortunately, with his agility and luck, Chen Hao successfully returned to his home.

But no one could have imagined that there was a trap here.

He was forced to travel through time after stepping into an empty house.

When he woke up again...his body had shrunk!?

And he met Ji Zi and her mother when she was a child.

He was adopted by chance and grew up as Jizi's childhood sweetheart/brother.

I thought it was the world of Honkai Impact 3rd. After all, who wants to cut off their own hope of living?

He hoped to save the tragedy with the help of the seven rings that came with him.

But you tell me this is a world bubble! ?

The reason for identification is simple..

"Human..what are you thinking?"

The white-haired girl in his arms blinked her scarlet eyes in confusion.

But since I'm here now, it would be a waste of my time traveling if I don't do anything.

So he drove the Hyperion (controlled by Ai Yi) and began to save the tragedy he knew in the sea.

Looking back, he found himself surrounded by many beautiful women, and then he naturally turned his attention to the eigenworld.

I thought I could finally push through all the way, but who could have imagined that this place was actually a pre-civilization?!

I just arrived a few days ago and found a pink-haired girl falling from the sky..
