[Quick transmigration + not a strong female lead + fixed couple + sweet romance + both leads' first love + conquest + mutual salvation]
"Ding! Congratulations, Host. Your binding is complete. Quick Transmigration System No. 518 is at your service."
Host's mission: Quick transmigrate into the roles of cannon fodder in various small worlds, correct the path to success of each world's favored child of destiny, and ensure every world develops steadily and sustainably!
The all-powerful Commander-in-Chief: "What does this vast river matter? As long as you stay by my side, you can give it to anyone you like!"
The gloomy, cold-hearted domineering CEO: "You can't escape! Stay, and I'll do whatever you want!"
The abstinent, scheming, ruthless Demon Venerable: "You brought me back to life, so you're responsible for me to the end! Sob, sob, sob!!!"
??? What??? Demon Venerable, you're completely out of character. Get back on script and say that again...
