The protagonist has a weak presence (he disappears later on), and the main and secondary plots are connected to the author's previous book, so it doesn't matter if you haven't read it.

Timeline: Collapse: The time is before the 2.0 main line and after the 1.6 main line

Collapse 3: In the third collapse, the three families were taken to Hyperion and returned to St. Freya Academy

(No female lead, no harem, the protagonist is a personified system that is only responsible for playing videos and performing functions, and will basically not appear.)

Lin Hai transmigrated into a system that requires him to collect emotional points in order to restore his body and obtain more of the rewards he has always dreamed of.

Driven by the power, a light screen suddenly appeared in front of many characters from Honkai Impact 3, Genshin Impact, and the Starry Sky Railway.

A series of videos began playing—

[Starry Sky Railway cutscene - "All or Nothing"]

The cry of "All for the King of Amber" resounded throughout the heavens and earth!

Sunday: Mr. Sand Gold, I think you should explain why you fought with others on the "family" territory.

Himeko: Mr. Sand Gold, I also need an explanation.

Huang Quan: Did I ever fight this person? I don't remember... I should probably touch the knife.

[Genshin Impact Cutscene - "The End of the Sinner"]

With a sword hanging over his head and his clothes fluttering, the sinner dances with swirling steps!

Navelette: Frynn...

Paimon: So this is the real water god... Waaah...

Zhongli: The title of Water God is well-deserved!

Lei Movie: This kind of spirit has reached a divine realm!

In addition, there are "Eternal Flame", "Flying Light", "A Story Because of You", etc.

Seeing the expressions on everyone's faces and the abundant emotional points he had gained, Lin Hai showed a satisfied expression.

A video recap system has arrived in Teyvat, showcasing tear-jerking moments and playing Frinna's storyline, including "The Sinner's Dance."

It brought tears to the eyes of both gods and men.

Ying: You have held on like this for five hundred years. Let me hug you.

Navilette: Thank you, I really enjoyed the five hundred years of the story.

Zhongli: I signed a contract with myself to save the country and kept it for five hundred years, which ultimately deceived the will of heaven. I respect all justice that needs to be practiced by myself. Even though the divine part has dissipated and the throne no longer exists, for the entire history of Fontaine, Funina is still a god of justice worthy of recognition.

Then the song "Broken Branches and Old Dreams" was played.

[The Great Compassion Tree King: Let the world completely forget me.]

Play [The Chapter of the Immortal Fox]

[Youlezhai, I was really happy, but now watching you leave, I still feel a little lonely.]

…

After all the tear-jerking PVs were played, everyone in Teyvat's eyes were swollen with pain!!!!!!

【Behind the scenes of the protagonist】

Su Yu traveled to the world of Xingtie and obtained the Mihoyo mobile game development system. His game therefore attracted attention from the entire universe.

When the player progresses to the Cocolia boss battle.

"Wildfire" sounded.

"Holy crap! This is too exciting! When the music started, I almost thought our opponent was a Star God!"

When the player progresses to the Immortal Boat.

Xianzhou players: Wherever the game is broadcast, there we will be caught in reality!

When the player progresses to the point where the firefly is pierced.

"Ah—the magic of dragon transformation is activated!"

"Danfeng, lead us in launching a Moon Drinking Rebellion!"

Before the plot

【Original God】+【Second Creation】+【Live Broadcast Room】+【Funny】+【Xie Ying】

(There is a protagonist, there is a protagonist, there is a protagonist, it’s important to say it three times!!!)

One day, Zhang Fan was doing a live broadcast in his rental house to help his fans play the 12th level of the Abyss in Genshin Impact. Suddenly, a bolt of lightning struck and he fell to the ground in front of his computer desk and lost consciousness.

After an unknown amount of time, Zhang Fan found himself transported to the continent of Teyvat, transformed into a baby. He was picked up by Ganyu, who happened to pass by and was adopted by the True Monarch Liuyun Jiefeng. However, due to his poor aptitude and incomprehension, he was unable to master the immortal arts, and without the divine eye, he could only cultivate martial arts. His combat effectiveness was only moderate, barely enough to defeat a few hillbillies. It wasn't until he awakened his video defense system at the age of 15 that everything changed.

Yingmei's crazy look: There is a flexible dog in the mountains

Keqing's eyelids twitched: "Traveler, I'm still very strong as a seven-star, T0 or something..."

Zhongli held the teacup in his shaking hands: Zhongli... the wear and tear has worsened.

Just when everyone in the Teyvat continent was still immersed in various secondary creation videos, the knife came quietly.

King of the Great Compassionate Tree: I am the one who proposes the question, and I am also the one who seeks the answer... Let the world completely forget me

Narcita: I...it's not me...

Ying: Shin, and everyone at Kitsaigugu...

Fernina covered her face and cried bitterly: Why, Fukaros...

So far, I have written "Asking the God", "Walking on the River", "Unawakened Dream", and "Glory of the Abyss".

Songs from the Ashes, The Road Not Taken, Footprints, We Will Meet Again. . .

"If You're Trapped in a Windless Land", "The World Forgot Me", "Sinner's Dance" . . .

On his way home, Xuan Yong, a social animal, was sent to the world of Collapse by the truck Dadi. He became the star god of destiny and obtained a live broadcast room to review the situation, causing the social death of each protagonist group (Honkai Impact 3, Genshin Impact, and Collapse Star Railway)

Su Hua accidentally connected the live broadcast system and was transported to ancient times, where the ancestors watched him.

When playing Star Dome Railway, everyone was amazed at the power of the star gods, and even exclaimed that there were real dragons in the world!

When playing FGO, the first emperor who ascended mechanically scared the emperors.

When playing Honkai Impact 3rd, the flawless Alysia made many literati write poems for her.

…………

The ancestors were dazzled by the games one after another.

How many worlds are there in this world?

[Movie Watch] + [Star Iron] + [Zero Zone] + [Genshin Impact] + [Joining Honkai Impact 3 after Chapter 100] + [Half-use Protagonist] As a college student, Yumo spends a lot of time playing the original Honkai Impact 3 game, Mijia San, and is fascinated by its characters and stories. So... "Ding," "You've connected to the Mihoyo Interdimensional Video Center. You can upload videos to earn points." ... Aha: This is so much fun! [Yellow Springs PV] [Eternal Rondo] [A Fable About the Starry Sky] [Pinocone] [...]

[Broken Iron] + [Live Broadcast] + [Comics] + [Challenge Monsters] A light curtain projects the story of Star Dome Railway to the heavens and the myriad worlds. The natives of each world are all amazed at the power of the star god, the vastness of the sea of stars, and the abstractness of the stars... Just when everyone can only see a novel story from the sky curtain, the opportunity to challenge monsters quietly comes. In addition to allowing them to better understand the world of Star Dome Railway, it also gives them the power to change their destiny. Regarding the strength of the monsters, Yingqiang, with trembling hands, smiled and said-very simple! (PS: The worlds I wrote are all those I have seen or played. I try not to be OOC, but it may be difficult to avoid. I hope you can understand. Finally, I wish you all a happy reading)
