The System Always Treats Immortal Lord as a Grassroots

Traveling through the world of immortality, Lin Xuan awakened to the "Low Martial Arts Achievement System". In this era of high-level magicians who move mountains and reclaim seas at every turn and wield swords for thousands of miles, the system solemnly awards such outrageous achievements as "a powerful fist", "flying on grass", and "a small achievement in internal strength". "Unlocking low-level martial arts achievements will give you generous rewards?" "But in this world, if I just throw a punch, it's over the limit, right?" "System, let me see how far your knowledge goes!" Since then, Lin Xuan has been constantly improving in the world of immortality. When he first introduced the air into his body—— [You have achieved the achievement of 'Internal Strength'! Reward: Root bone fine-tuning! When he was refining the third level of Qi—— Warning! Your energy reserves have surpassed those of the great masters of the low martial arts world! Unlock the title 'Martial Arts Master'! [Reward: The meridians are widened! When he wielded the flying sword for the first time—— [It has been detected that you have achieved the feat of 'Conquering Thousand Catties of Things'! This is the legendary 'controlling things with Qi' in the world of low martial arts! [Unlock the hidden achievement: 'Sword Immortal Lin Chen'! Many years later, Lin Xuan stood at the top of the immortal world and was respected by all races as the "Ancestor of Wuji Taoism". Faced with this title, Lin Xuan helplessly raised his forehead: "Dao Ancestor? The system was blocked when I was in the Qi Refining Stage..." (This book is also known as: "First Level of Qi Refining, Do You Say I'm the Taoist Ancestor?" "System, Please Stop Making Blind Judgments!")
