You Tell Me I'm a Prince Right After I Graduate?

Tang Chen transmigrated to a dynasty unlike any he had ever seen. He had only wanted to make money in peace and live as an idle prince.

But seven days later, he unexpectedly transmigrated back. As a time traveler between two worlds, watch Tang Chen dominate both realms and roam wherever he pleases.

The ancient world has low productivity? I'll build a steam engine and haul supplies to the front lines.

Emperor: You rebellious brat, get back here! Keep this up and the people will rise in revolt!

Coach: Come on, man, did you just tell me you can bench-press 900?

Modern world: That kid just beat a bear to death with his bare hands. He's practically a god!
