(Two worlds, government involvement, reverse engineering)
After transmigrating to the world of Tailong for two years, he returns to Earth.
But now he's got a bunch of Tailong resistance fighters at his side, shouting that they'll eat him if he doesn't obey.
Come on, man!
Do you even know whose home turf this is?
Let's see if my rich dad's fifty thousand security guards don't beat you senseless.
That's just the protagonist's fantasy. Here's what really happens:
In the conference room, the top brass ask, "Who's going to take responsibility if Earth's first contact with another world goes south?"
Dad says, "Son, we'll put off rescuing you for now. Tell me, what does the other world need? Food? Fine, I'll buy up a few agricultural companies in advance."
A livestreamer cries, "Luo Xia! You're Luo Xia! Didn't you go missing two years ago? Why have you shown up now?"
Mu Sha, the resistance leader, happens to witness this and asks suspiciously:
"Luo Xia? How does anyone on this planet know you? Aren't you from our planet, Tailong?"
The title isn't flashy, and the livestream starts in Chapter Four.
P.S. There isn't much combat, and there's more dialogue and drama. There's no System either. The author believes that a truly challenging, compelling story doesn't solve everything with violence or cheat powers.
