Do you think the world you live in is normal?
In the corners you can't see, martial arts masters can break boulders with one punch, Feng Shui masters can decide life and death with a single word, and secret families that have been passed down for thousands of years compete in the shadows of the city.
And all these secrets are hidden in an ordinary municipal library.
As the only administrator, Lin Mo just wants to get off work on time.
Until he activated the sign-in system that connects all the worlds——
Read and you will gain strength!
Learn the magical acupuncture from "Treatise on Febrile Diseases and Miscellaneous Diseases", understand the meaning of the sword from Wang Xizhi's original works, and master the secret skills of organs from "Lu Ban Shu"...
When the world's order is about to collapse and everyone thinks the end is coming, light shines from the library.
It turns out that knowledge is really the strongest power!
