As a child, Lingfeng suddenly gained the ability to travel through the world and also obtained an exchange panel.

At the age of 7, he accidentally traveled through the fairy boat and became a disciple of Jingliu, where he learned Jingliu's true swordsmanship and embarked on a path of destruction. At the age of 17, he participated in the Third War of Plenty as a general.

After traveling again, he became a member of the Starry Sky Train.

Lingfeng suddenly disappeared from this world for a full thirty years.

Technology has developed rapidly in the past 30 years. Countries have joined forces to create a memory viewer. As long as you put the missing person's belongings on it, you can explore the missing person's experiences from the past to the present.

This machine is used in an entertainment program called "The Unknown Secret". Every time it is broadcast, tens of millions of people watch it. It has always been at the top of the entertainment charts and is the most talked about program.

Until one day, a woman placed a piece of her son's belongings who had disappeared more than 30 years ago on the instrument, and the whole Internet was immediately in an uproar.

It's no secret that he carries the world on his shoulders.

Everyone knows about his attack on the Void Number Tree.

Lingfeng placed one hand on a large golden tree (the Tree of Imaginary Numbers), and turned to walk towards the train that crossed the galaxy.

"This is... our way home!"

A few days later, several letters were suddenly found at home.

"Who is Fu Xuan? What does the Nameless Guest badge do?"

"Who is Hanabi-sama?"

[Day 1 of the time travel: Wearing Adi King's battle suit and dark red hair, is Emiya Shirou actually me?]

[Day 3: Confirmed, this isn't the UBW questline, no Red A experience packs, so I'll have to rely on myself to master Unlimited Bladework.]

[Day 20: Strengthened my magic proficiency and began practicing Projection. During this time, I met an alchemist who asked me where I got all these alchemical weapons made from recycled metal.]

What the hell is recycled metal?

[Day 90: Finally mastered my first Noble Phantasm, Projection. They exclaimed, "This is the Seven Kingdoms," an outstanding achievement in alchemy."]

Huh? I don't really understand you alchemists.

...

[Day xxx: Huh, I finally mastered Unlimited Bladework! Their expressions were fascinating, and they asked where the Nibelungen was.]

How come you don't even know about the inherent barrier? Isn't this... Type-Moon!?

After the Great Collapse, the year is 2029. The stargate opens wide, and the "Celestial Beings" draw ever closer. Welt and Void Archives pass through the stargate and arrive at the "Celestial Beings'" base. The base's data reveals information about another universe. Why does the person in the data look exactly like Himeko? Even though Himeko Murata is already...

After learning the information, Kiana decides to follow Welt to another universe to stop the "Celestials".

The timeline is from the end of the official comic, Away from Home, where Welt travels to the Star Iron Universe.

If, and I mean if, the monsters you kill in the game are actually real human lives, would you still enjoy hack-and-slash games? "What the hell? Getting all sentimental over a game." "If that day ever comes, I'll be the first to choose the blue pill and travel back in time to slap the OP." "I'll talk to you later, someone's checking the water meter at the door, wait two minutes."... An Yu transmigrated, has a beautiful boss Bronya, a fat older sister, and a job designing the world's lore—a happy and fulfilling life. But I just played a hack-and-slash game, and you insist I'm guilty of a heinous crime? An Yu points at her older sister: "You insist I kill ordinary people while hacking and slashing, then show me how to transform into a Herrscher of the Origin!" "Go ahead and transform!"
