The librarian Su Zifeng passed through time due to a fire. A beggar who was about to be killed was picked up by Miss Li, a wealthy businessman from the Qingzhou Prefecture of the Great Xia Dynasty. From his memory, he learned that there are powerful warriors in this world who can cut off rivers with a sword, open mountains with a punch, and cause the sky to collapse. Su Zifeng expressed panic, but fortunately the library came with him and mutated.
Ps This book belongs to the invincible stream, and there is only a very small part of the protagonist's growth line [the introduction is weak, please move to the main text]
