The Doted-Upon Crown Prince's Everyday Lie-Flat Life [Qing Dynasty Transmigration]

Upon transmigrating, Yonglian became Emperor Qianlong's white moonlight son, Duanhui Crown Prince, who died young at eight years old.

Six-year-old Yonglian, resting his chubby face, fell into contemplation. If he didn't try to survive, he would die in two years. If he tried to survive, he'd have to be the Crown Prince for over sixty years... His second grand-uncle was driven crazy after being Crown Prince for forty years; sixty years as Crown Prince...

Wait a minute? Secret succession is currently in practice. Besides Emperor Ama, no one knows he's the Crown Prince, including himself. Since that's the case, he'll just lie flat for now.

Now the pressure was on Qianlong. The little Crown Prince he chose was frail, mediocre in studies and archery, and his personality was as soft as dough. What could he do? This was the precious Crown Prince born to him by the Empress! At worst, the Emperor Ama would just work a bit harder.

Reject extravagance and waste, must save more money for Yonglian. Cannot close off the country, Yonglian likes Western things just like Emperor Shengzu. Purge corrupt officials, lest Yonglian be deceived by these old political foxes later. As for literary inquisitions, there's no time for that; who has the leisure to nitpick words when there's construction to do?

...

As Yonglian continued to lie flat, he discovered that the Qianlong era was no longer a false prosperous age. Excellent, he could continue lying flat. Until one day, he found that Emperor Ama had secretly taken down the imperial edict of succession from behind the plaque.

Yonglian: ? Has Emperor Ama finally had enough of him, this salted fish, and wants to change Crown Princes?

Qianlong: I can't keep striving anymore, what should I do if I want to abdicate early?
