Wuxia Crossover: Sign-In from the Start, Stealing the Lin Family Sword Manual

Reborn as a concubine-born son of Jiuding Manor, Lin Ye brings with him a martial arts sign-in System. From the start, he signs in to receive the Muscle-Tendon Transformation Scripture and reaches the third level of the acquired realm overnight. From the library to the pinnacle of the martial world, he grows stronger through daily sign-ins, snatches the Lin family sword manual, stands up to his legitimate elder brother, and stirs up the martial world of Great Xia.
