Su Yan was kicked out of her home by a wealthy family and was ridiculed by the entire Internet for three years. Everyone thought she was just a vase who caused trouble. It wasn't until a live broadcast between the two worlds suddenly started that the entire network discovered that she was actually "Biao Xiao", the top commander in China who had been missing for three years. Guarding the supernatural defense line at the age of nineteen, and guarding the abyss alone at the age of twenty-two, she has already become the last line of defense between the human world and the supernatural. Now Lu Wei starts a live broadcast at his own expense, making the truth and military exploits that were buried three years ago public. The people who scolded her in the past began to regret, and the people who framed her were exposed one after another, but Su Yan no longer cared about this. What she wants to do is to eliminate the inner ghosts, control the underworld, and then raise her sword to attack the divine realm outside the country - in this life, she will protect the human world and slay the gods.
