Martial Arts Check-In: from a Boy from a Mountain Village to a Martial Artist in Jiangcheng

Lin Chen is a descendant of a declining martial arts family in Qingwu Mountain Village. He has been practicing the family's inherited martial arts with his grandfather since he was a child. He uses his solid body to help the villagers resist monsters, but he is unable to improve since he does not have high-level skills. When his 18-year-old grandfather passed away, he asked him to go to the city to take the martial arts college entrance examination and be admitted to the Jiangcheng Martial Arts University. Before leaving, Lin Chen accidentally bound the martial arts global sign-in system, which can unlock rewards such as exercises and magic weapons at specific locations. When he first entered Jiangcheng, the plainly dressed Lin Chen was looked down upon by the urban martial arts disciples. He took advantage of the system to counterattack: he signed in at the station and received a body-tempering liquid to advance to his physical body. He signed in at the test center and gained mastery of fast boxing and complete knowledge of martial arts theory. He scored full marks in the written examination and KOed wealthy geniuses with one punch in actual combat. He was successfully admitted to Jiangcheng Martial Arts University. After enrolling in school, Lin Chen learned about the secrets of urban martial arts: ancient formations are buried in skyscrapers, monsters are hidden in many places, martial arts practitioners need to hunt monsters in exchange for resources, and large companies are mostly martial arts forces. He continued to become stronger by relying on the system. He unlocked high-level skills in the martial arts field, obtained the True Eye of Treasure Appraisal in the Antique City to earn training resources, learned the art of array pattern at the formation eye node, and unlocked the basic beast-controlling ability by the river. While completing hunting missions to earn credits, he also slapped the wealthy forces in the face, conquered his followers, and became a new leader. He sensed a crisis in Jiangcheng: high-level monsters wanted to break through the city formation, and degenerate martial arts forces colluded with the monsters to cause chaos. Lin Chen teamed up with his mentor and the hidden family, and relied on the "Demon Suppression Technique" unlocked by the system to quell chaos and strengthen the formation many times, and grew into the genius of Jiangcheng's martial arts. In the end, he signed in at the center of Jiangcheng's central square and gained the power of martial arts to reach the pinnacle of urban martial arts, becoming a martial master in Jiangcheng. When the tide of monsters comes, he fights the leader, suppresses the lair and protects the whole world.
