Sign-In: Thirty Days to Invincibility

Lin Xiuran transmigrated into a world of advanced martial arts and awakened a sign-in System. One month later, the world's mightiest expert had appeared.

Student at the Modu Martial Arts Academy: "That guy's a freak. We're not competing with him."

First-Rank Aristocratic Family: "Starting today, we will close our doors and refuse all visitors. No one in the clan is to cause trouble!"

Supreme Royal Clan: "This is outrageous! You actually... Since things have come to this, you two should pick a date and get married."

Imperial Clan: "Lin Xiuran, don't push your luck! You think our clan's forbidden grounds are your backyard, where you can come and go as you please?!"
