Quick Transmigration: From Snowpiercer to Warhammer 40k

[Quick transmigration + crossover of film, television, games, and anime + no romantic pairing + no male lead + pseudo-D&D + Warhammer 30k]

Having read so many stories about expensive adoptive fathers in Warhammer, I've hardly ever seen expensive adoptive mothers, so I'll write one myself.

You asked her what she did?

She only wanted to save her own little planet, but ended up dragging Cybertron to be her neighbor; she learned dragon shouts in the Elder Scrolls world, then devoured Smaug from Lord of the Rings; Night City was transformed under her rule, and she's a frequent visitor to the Warhammer world. Oh, and she even kidnapped the Primarch!

Reading reminder:

I'm a novice writer, so please be gentle with my writing!

The protagonist is a native of the wandering Earth, and his faction is of good order (commonly known as a great person).

The cheat code is huge (modified D&D spells), and it's not stingy.

The protagonist is being targeted by the Royal Pitts, and there will be more Warhammer elements starting in the mid-game.

He's alone in the early stages, but he'll cooperate with the country (the plot of The Wandering Earth unfolds rather slowly).

He doesn't believe in any particular method; he teaches students magic.

It's not a purely female-centric story; both male and female characters will appear.
