People from the modern world transmigrating into the ancient Chinese fantasy world has become a common and everyday occurrence that the royal court in the latter has decided to moderate them. If you’re a transmigrator, you must report your existence to Lou Zhu, the master of Best Tower. Once you pass his test and prove that you are indeed a modern person, you can then be assigned to work in different areas of the government and be given a high salary.

Because of this promised benefit, many impostors have appeared before Lou Zhu. And one day, Zuo Yunqi takes this test as well. Is he an impostor, or is he an actual modern person?

But some transmigrators also choose to hide their existence out of distrust in the government. Where are they? And with their advanced knowledge on science and technology, what are they planning in the dark?

Elsewhere, other transmigrators find themselves in all sorts of situations—an art student is detained and forced to come up with a recipe for a poisonous meal, while another is stuck sharing a body with the original soul and fighting for its control. Meanwhile, unrest rises in the Jianghu and a storm brews in the palace. Can our transmigrators’ modern knowledge save the day? Or will their lack of understanding in the current world lead to their downfall?
