After opening the ancient well in his backyard, Li Yin’s life has changed since then!

Sixth Prince Li Yin? 21st century otaku Li Yin? He can travel freely between the two worlds, what kind of life should he choose?

Harem? Hegemony? trickery? Is that all?

No! With the advantages of modern technology, he wants to build his fiefdom into the economic center of the world, and the world map will be filled with his colonies…

PS: This is written about the Tang Dynasty, but it is a parallel time and space. There is no need for historical burdens, and it will be a little different from the real Tang Dynasty. Please don’t be serious about the textual research party, because some small details like titles are annoying. This is not what I wanted, thank you!

- Description from novelbuddy

At 18, Alex Kain is whisked away to Eryndor, a game-like realm where he gains 'Skill Synthesis', a talent to fuse skills into godlike powers. Battling monsters and conquering dungeons, he builds a harem of strong women drawn to his might and charm. With the power to return to Earth bearing incredible resources, Alex faces a growing threat that endangers both worlds in this epic of adventure, romance, and ambition.

The second prince has come of age. To celebrate the advent of such an occasion, the search for a suitable bride began. My younger sister was expected to go to the Royal Palace as a candidate. However, despite this, she eloped the day before her departure. I, the older sister she left behind, looked almost exactly like her – so much that we were often mistaken for twins…

One month, right? For just one month, shall I substitute in for my sister?
