Martial Arts Have Mastery

"Shen Ling was transmigrated into another world where he became the sick eldest son of the Shen Family in Qi City. Just as his life was about to end, he activated the Golden Finger. ""You have completed one week's worth of Life Prolonging Arts. Mastery +1."" ""You have mastered the Mountain Splitting Sowrdstyle. Mastery +5."" It was then Shen Ling realized that cultivation was way easier than he had thought."
