The Library of Ten Thousand Dynasties

The Hardcore Guide to Protecting the Nation, Courtesy of a Couch Potato

Chen Zhixian only wanted to be a couch potato, living off others until the end of her days. Who knew her family library would get a cheat, transporting her and all its books to the Great Qin dynasty more than two thousand years ago, where she met the adorable and captivating ancestors of old!

As soon as Chen Zhixian returned home, she promptly handed the System over.

After the Library of Ten Thousand Dynasties was built, emperors and famous figures from every dynasty gathered there, setting off on all kinds of adventures.

When the ancestors learned how much the children had been bullied, they said, "Just what have these kids been through?"

Later, after they had pushed themselves harder and harder, the people of the Western nations watched as the Chinese, who had always loved farming and peace, suddenly became mighty warriors. "What the heck! Has China got a cheat or something? ... Why can everyone fight?"

Chen Zhixian: "Ancestors, look, the whole world has been unified. Maybe it's time to look beyond our borders."

Ying Zheng and the ancestors of every generation: "...So you don't want to suffer even a little, is that it?"
