A Handbook for Growing Up [Crossover]

[This story has been serialized for a long time and covers a broad span. The first two worlds have both been thoroughly revised, though the main changes were to the writing style. Please forgive the plot's rough edges.]

[The third world has not yet been polished, so the style may differ quite a bit.]

[The story was originally titled "Want a Hug? [Crossover]", then renamed "The Zha Gong Growth Manual [Crossover]", and is now titled "Growth Manual [Crossover]".]

Lu Zhiqiu dies unexpectedly, gets bound to a System named 027, and travels to various worlds.

The F4 of an elite academy; a long-lived vampire family with a demon king and young masters; spirited boys in a swimming club; Tokyo's celebrated great detective and phantom thief...

His stories with them may have only just begun.

Reader's Guide:

1. The protagonist is the pursuer, with no role reversal. He's probably a gentle, growing type who charms everyone (?)

2. The style is quite old-school, so readers with strict preferences are advised to avoid it.

3. There are love triangles and OOC. The ending has no pairing.

The complete story is free to read. The sequel, "I Make a Living as a Virtual Boyfriend [Crossover]", is also available in my author profile. Don't miss it as you pass by!

Here's the blurb:

When Lu Zhiqiu opens his eyes again, he's surrounded by several handsome young men.

They tell him this place is a honmaru, and he's its new Saniwa.

The place called a honmaru is rundown, and the dust and cobwebs in the corners could be used to weave a blanket.

The young men chatter away about things Lu Zhiqiu can't understand. At last, they send forward a teary-eyed boy to ask him, "Saniwa, you'll make the honmaru better, won't you?"

Lu Zhiqiu: "..."

After living here for a while, Lu Zhiqiu discovers that the honmaru lies in a rift in time and space. Standing in the courtyard, he can talk to people outside.

A pure-blooded young wizard from a noble family, a billionaire playboy from New York, a rich kid from Gotham... Ha, they've really hit the mark with his poverty.

Then there are Japanese high schoolers with all kinds of strange abilities, who leave Lu Zhiqiu feeling guilty, as if he's scamming children out of their pocket money.

...What else can he do? Grow crops and sell goods. There's nothing else to this ramshackle honmaru.

At most, he can also help the people on the other side with their life or relationship problems.

Until one day, someone asks him, "What does a date mean? Can you come meet me?"

Lu Zhiqiu: Oh, so I'm not just taking their money.

...I'm selling my charms, too.

Later, Lu Zhiqiu travels back and forth between the honmaru and the real world, bringing his blades with him.

He stays in Tokyo for a while. Tiny Tokyo, where the world ends every few days.

He goes on a trip to New York. Vast New York, with an alien spaceship even bigger than the city.

He flees to London. High above Europe, someone rides a broomstick outside the plane window, while a magical duel shakes the skies.

Hey, you're going to hit the plane!

What kind of world is this!?

Being forced to work, forced to sell his charms, and chased by creditors over money and romance would be bad enough. But why does disaster strike everywhere he goes?

...Is he going to be forced to save the world, too!?

Theme: No matter what, live with effort, passion, and sincerity.
